  社會實踐和學習同樣重要

  There is a growing awareness of the equal importance ofsocial practice and academic learning in todays world.Some believe that social practice is thekey to success,whileothers arguethat it is not compulsory for everyone toengage in.Personally,I find the former view morereason-able.

  Firstly,social practice is essential for students.It allows themto apply what they have learned in the classroom to real-lifescenarios,enhancing their understanding and reinforcingtheir knowledge.For example,participating in internships orvolunteer work can provide students with valuable insightsinto their chosen field and help them develop practical skillsthat cannot be learned from textbooks.Secondly,in theworkplace,employers value individuals who can effectivelycollaborate,communicate,and adapt to different situations.Lastly,in daily life,social practice enables individuals to in-teract effectively with others,resolve conflicts,and make in-formed decisions.

  In conclusion,social practice and academic learning are ofequal importance in todays world.By recognizing and em-bracing the value of both,we can foster a society thatvaluesknowledge,practical skills,and social responsibility.

  六級聽力第一套

  Conversation one.

  ive just bought a new blender.

  Whats that a blender?

  A machine that blends food.

  the electric kitchen appliance, exactly.

  This one is state of the art. Ive been meaning to buy one for a while. I did thorough research on which specific model to get. I read through maybe hundreds of online user reviews. Anyway.

  its amazing really what could be so special about it. I its just a blender.

  Basically its just a very good one. It feels heavy and sturdy and well made. It also has lots of power and can easily cut and crush practically anything. This way. The soups and juices I make come out really fine and smooth with no lumpy bits.

  I see I have never thought of getting one myself. It sounds like the kind of thing that for me personally I would rarely use.

  Ive never had one before now that I do, I use it all the time. I make a fresh fruit juice in the morning, maybe not every morning but 3 or 4 times a week and it feels fantastic. Its a really healthy habit.

  I can imagine that must feel quite satisfying. I can picture you getting all creative in the kitchen and trying out a multitude of different ingredients. Its obviously going to be healthier than buying packaged juice from a supermarket.

  Its so much healthier. Its not even close did you know that store bought juice is like 10% sugar, right?

  Then you bought it for the health benefits, mostly yes.

  Basically, it allows me to have a more varied diet with a far wider assortment of nutrients, because its not only fruit in my morning juices. You see. I can also throw in vegetables, nuts, yogurt, cereals, anything that tickled my fancy.

  Questions. 1 to 4 are based on the conversation you have just heard.

  Question 1, what does the man say he did before buying the blender?

  Question 2, what does the woman say she has never thought of doing?

  Question 3, what does the man say is a really healthy habit?

  Question 4, what do we learn about store bought juice from the conversation two?

  Today we have a very interesting guest, mister thomas benjamin grimm, the mayor of burkington is here to talk about his job and responsibilities overseeing this charming village. Mr. Grimm, thank you for being here.

  Thank you for having me.

  Id like to start by stating the obvious burketon has become one of the most popular tourist destinations in the country and this has happened under your watch. Just how did you achieve this?

  The achievements belongs to all the residents of burton. It was a shared effort where everybody pitched in for the communal good.

  But how did this change happen? In about 10 years, burkton has gone from a relatively unheard of sleepy village to a must see destination.

  Yes, the change has truly been remarkable. Burkton was always fortunate to be endowed with such a beautiful natural allure. The anbury hills above the village remain untouched by human development. The sonora valley just below it is equally stunning. The transformation commenced in a town hall meeting in spring 2008 over 10 years ago. Now when an overwhelming majority of neighbors voted in favor of motion, 836, this legislative proposal essentially set out to harmonize the aesthetic appearance of all the houses in berkton. The idea was that if all the properties looked a certain way with shared design features, then the village as a whole would look more beautiful. It worked, it certainly did.

  Im looking now at a before and after photo and the change is truly remarkable. Its hard to believe its the same place. How do the neighbours feel now? Great pride.

  I would say.

  But what about the multitudes of visitors now crowding the streets? Is everyone happy about that?

  The tourists we receive are a blessing as they have completely revitalized our local economy. Every visitor is warmly welcome.

  Questions 5 to 8 are based on the conversation you have just heard.

  Question 5, what is the question the woman asked mister grimm after the introduction?

  Question 6, what do we learn about burkton of 10 years ago?

  Question 7, what resulted from the passing of the legislative proposal motion 836.

  Question 8, why does the man say the tourists are a blessing to bergen? Passage one,

  researchers in the us have created a remote controlled robot that is so small. It can walk on the top of aus penny in research published in the journal science, robotics. A team at northwestern university said the crab like robot is 0.5 millimeters wide. Researchers described it as the smallest ever remote controlled walking robot. The tiny robot can bend, twist, crawl, walk, turn and even jump without the use of complex hardware or special power. The engineers said this is because the robot is powered by the elastic property of its body. To construct the robot, the researchers used a shape memory alloy material that transforms to its remembered shape when heated using a laser, the team is able to heat the robot at specific parts of its body, causing it to change shape as the robot deforms and goes back to its original shape. It creates movement from one place to another, because these structures are so tiny, the rate of cooling is very fast. Project lee, professor john a rogers said, in fact, reducing the sizes of these robots allows them to run faster. While the research is still in the exploratory phase, the team believes that technology could lead to micro sized robots that can perform practical tasks. In tightly confined spaces, you might imagine micro robots as agents to repair or assemble small structures or machines in industry or a surgical assistance to clear clogged arteries to stop internal bleeding or to eliminate cancerous tumors all in minimally invasive procedures. Rogers said.

  Questions 9 to 11 are based on the passage you have just heard.

  Question 9, what does the passage say about a team of researchers at northwestern university?

  Question 10, what did the researchers say about the robot they created?

  Question 11, what do the researchers expect their robots to do in the future?

  Passage two, I dont want to boast or anything, but I have always considered myself something of an elite sleeper given the opportunity, I will sleep for marathon stretches and condose through the most extreme situations on one very rough ferry crossing on the route to the isles of silly. For example, my traveling companion spent the entire 3 hour ride throwing up in the bathroom while I dozed happily on a plastic chair. Unfortunately, it has come to my attention that I am not an elite sleeper. After all. It seems I am just lazy because elite sleepers are defined as the approximately 3% of the population who are biologically programmed to need less sleep than the rest of us. According to a study that came out in march, elite sleepers have rare genetic changes, which means they can sleep fewer hours than mere mortals without any risk of cognitive decline, it may not be possible to change your own genes, but can you train yourself to need less sleep? Is there a non biological way to reach elite sleeper status? I have spent the past year trying to answer that question, not for fun, I should add because having a baby has severely disrupted my sleep for which I still have a great passion for a while. I assumed id be forced to become one of those people who jump out of bed at the crack of dawn. After a year of tough scientific study, however, I have discovered being forced to get up early in the morning is very different from being an early bird.

  Questions 12 to 15 are based on the passage you have just heard.

  Question 12. What does the speaker say she did on her ride to the isles of silly

  Question 13. What do we learn from the passage about elite sleepers?

  Question 14, what has the speaker been trying to find out over the past year?

  Question 15, what has the speaker discovered after a year of tough scientific study?

  Recording one if you read an article about a controversial issue, do you think youd realize if it had changed your beliefs? No one knows your own mind like you do. It seems obvious that you would know if your beliefs had shifted. And yet a new paper in the quarterly journal of experimental psychology suggests that we actually have very poor awareness of our own belief change, meaning that we will tend to underestimate how much weve been swayed. By a convincing article, the researchers recruited over 200 undergraduates across two studies and focused on their beliefs about whether physical punishment of kids is an effective form of discipline. The students reported their initial beliefs about whether physical punishment is an effective way to discipline a child on a scale from one completely disbelief to nine completely believe. Several weeks later, they were given one of two research based text to read. Each was several pages long and either presented the arguments and data in favor of physical punishments or against it. After this, the students answered some questions to test their comprehension and memory of the text. Then the students again scored their belief in whether physical punishment is effective or not. Finally, the researchers asked them to recall what their belief had been at the start of the study. The students belief about physical punishment changed when they read a text that argued against their own initial position. Crucially, the memory of their initial belief was shifted in the direction of their new belief. In fact, their memory was closer to their current belief than their original belief. The more their belief had changed, the larger this memory bias tended to be suggesting the students were relying on their current belief to deduce their initial belief, the memory bias was unrelated to the measures of how well theyd understood or recalled the text, suggesting these factors didnt play a role in memory of initial belief or awareness of belief change. The researchers concede that this research was about changes to mostly moderate beliefs. Its likely the findings would be different in the context of changes to extreme or deeply held beliefs. However, our beliefs on most topics are in the moderate range. And as we go about our daily lives reading informative material, these intriguing findings suggest we are mostly ignorance of what we just read has updated and altered our own position. Questions.

  16 to 18 are based on the recording you have just heard.

  Question 16. What does a new paper in the quarterly journal of experimental psychology suggest?

  Question 17, what happened when the students read a text that argued against their own initial position?

  Question 18, what did the researchers concede concerning their findings according to as the american population grows?

  So does the number of american moms recording to as the american population grows? So does the number of american moms, but more than a century after mothers day became an official holiday. Even as that number increases, the share of the american population who are mothers is at the lowest point in 1/4 century. Its frequently noted that fertility rates are falling sharply in richer countries, but the less observed consequence of this trend is that a decline in births can also mean a decline in motherhood in general. According to my analysis of data from the census bureau, the decline of american motherhood is real occurring very quickly and may continue for some time yet. Not only are moms making up less of the population, but their characteristics are changing too. And in a way that might be linked to their proportional decline, moms today tend to be older than in the past. Just looking at recent years, the change in age specific birth rates has been drastic. In just the past few years, the peak childbearing age range for american women has advanced from that of 25 to 29 that To 34. Meanwhile childbearing among women under 20 has fallen by half or more. While childbearing among women 35 and older is rising. One positive consequence of this age shift is that a larger proportion of new mothers are economically prepared to raise children less positively. However, many women find that as they age, they cant have as many kids as they would like. Plus having children later in life can increase the risk of health complications. These finer points aside, one major consequence of the older moms trend is that fewer years of a womans life are spent as a mother. This means that at any given time, a larger share of women and thus of the whole population will report not having children in government surveys. In other words, later motherhood means less motherhood, even as motherhood rates decline, mothers day will endure. In fact, despite the demographic shift, retail spending on the holiday appears to be rising. It is hard to say if mothers day spending is rising more than one would expect, given that the american population keeps growing. But one factor might be that the proportion of women who are the mothers of adult children is rising. Those adult children may spend more generously when it comes to celebrating the moms. They no longer live with.

  Questions, 19 to 21 are based on the recording. You have just heard.

  Question 19. What does the speaker conclude from her analysis of the census bureaus data?

  Question 20. What does the speaker say is a positive consequence of the age shift in childbearing?

  Question 21. What might be one explanation for the rise in retail spending on mothers day?

  Recording three. Since nasa published a paper in 1989, claiming that house plants can soak up pollution and toxic chemicals, businesses and homeowners have increasingly invested in greenery to help clean their air. But a new analysis suggests it could actually take more than 1,000 plants per square meter to gain a benefit any greater than simply opening a couple of windows. The problem lies in the fact that NASA conducted their tests in sealed containers that do not simulate the conditions in most peoples homes or offices. The space agency was primarily concerned about keeping the air fresh for astronauts cut off in biosphere or space stations and helping to combat sick building syndrome, which had become a problem due to the super insulated and energy efficient officers of the late 1970s. By the early 1980s, workers regularly complained of skin rashes, sleepiness, headaches and allergies as they breathed in toxic chemicals from paints and plastics. Nasa found that certain plants could remove chemicals from the air. And even today, garden centers recommend the plants for air cleaning properties. However, a new evaluation of dozens of studies spanning 30 years found that house plants in a normal environment have little impact. In fact, natural ventilation is far better at cleaning the air. The researchers also calculated the clean air delivery rates for plants in the studies they analyzed and found that the rate at which plants dispersed the compounds was well below the usual rates of air exchange in a normal building caused by the movements of people coming and going opening doors and windows. Many of the studies did show a reduction in the concentration of volatile organic compounds over time, which is likely why people have seized on them to praise the air purifying virtues of plants. But the researchers calculation showed it would take 10 to 1,000 plants per square meter of floor space to compete with the air cleaning capacity of a buildings, air handling system, or even just a couple of open windows in a house. In contrast, NASA sealed experiment recommended one pot plants per 100 square feet. This is certainly an example of how scientific findings can be misleading or misinterpreted over time. But its also a great example of how scientific research should continually re examine and question findings to get closer to the ground truth of understanding whats actually happening.

  Questions 22 to 25 are based on the recording. You have just heard question 22. What does nas as 1989 paper? Claim house plants can do.

  Question 23. What is said to be the problem with nas as study reported in its 1989 paper?

  Question 24. What is the finding of a new evaluation of dozens of studies spanning 30 years?

  Question 25. What does NASA sealed experiment recommendation exemplify in scientists pursuit of truth?

  Thank you for meeting with me,steven at such short notice。

  not a problem,margaret。Now please give me some good news。Have you agreed to my last proposal?

  I have indeed and I wish to sign the agreement pending one small change to be made to the contract。

  Margaret,we have been through this for almost a year now back and forth making alterations。Are you sure you want to make a sponsorship deal for your clients or not?I ask this because frankly,some people at my end are running out of patience。I understand your concerns。

  but as im sure you understand,we hold our clients best interests to be of the utmost concern。We therefore comb through the fine details of all contracts。Rest assured we all appreciate your firms patience。

  Fine。So what changes do you wish to make?

  Essentially,we would like the new deal to exclude the middle east。

  Thats all the middle east。

  Why my client has a couple of other perspective marketing deals from companies in the middle east。Those offers should they materialize would exclusively employ my clients image in the middle east only。Therefore,in order to avoid any conflict,we would need to ensure that both marketing campaigns do not overlap geographically。

  What business sector in the middle east are we talking about here?

  Real estate.

  that should be okay then so long as the product is very different from our food and beverage market,there should be no conflict of interest。Nevertheless,I will have to run this through my people。I dont foresee any problem though,the middle east is a negligible market for us,but I still need to check this with a couple of departments。

  Questions 1to4 are based on the conversation you have just heard。

  Question 1,what does the woman say she will do?

  Question 2,what does the man say about some people he represents?

  Question 3,what reason does the woman give for the new deal to exclude the middle east?

  Question 4,what does the man say about the middle east?

  Next,we have a special science related news story。Paula hancock is at the denver observatory。Paula,what is the big story over there?Hi.john.All the astronomers on site here are very excited。In fact,space enthusiasts all across north america and the rest of the northern hemisphere will be congregated on mountain tops tonight to watch the night sky。

  Whats the big event?Is there an eclipse happening soon?

  Tonight the earth will come into close proximity with the oppenheimer comet。It is the closest our planet has been to such a phenomenon in over 100years。For this reason。It is expected that thousands of people will gaze up at the sky tonight in order to see this formidable object。

  How far away is this common?Will people be able to see it with the naked eye?

  The oppenheimer comet will still be millions of miles away on the edge of our galaxy。But nevertheless,this is a relatively close distance,close enough for people to observe in good detail through a telescope。People will only see a blur without one。However that does not mean one needs professional equipment。Even the most ordinary of telescopes should be conducive for people to observe and wonder at this flying object。

  Many of our viewers will be wondering how they too can take part in this once in a lifetime event。Where will this comment be in the sky?How can people find it?

  The comet will be almost exactly due north at60°above the equator。However,finding the comet is indeed very tricky and scientists here have told me there are plenty of phone apps that will facilitate this。

  How fantastic?Thank you,paula for the information。

  Questions 5to8 are based on the conversation you have just heard。Question five,what does the woman say about all the astronomers at the denver observatory?

  Question 6,what do we learn from the conversation about the oppenheimer comment?

  Question 7,what does the woman say?People will only see in the sky without a telescope?

  Question 8,what do scientists at the denver observatory advise amateurs do to facilitate their observation。

  single line through the center。Passage one,

  dietary guidelines form the basis for nutrition advice and regulations around the world。While there is strong scientific consensus around most existing guidelines。One question has recently stirred debate。Should consumers be warned to avoid ultra processed foods?Two papers published today in the american journal of clinical nutrition outline the case for and against using the concept of ultra processed foods to help inform dietary guidelines beyond conventional food classification systems。The authors,carlos monteiro of the university of sao paulo and arna ostrich of novo nordisk foundation。Well discuss the issue in a live virtual debate。August14th,during nutrition,2024live online。The debate centers around a system developed by monteiro and colleagues that classifies foods by their degree of industrial processing,ranging from unprocessed to ultra processed。The system defines ultra processed foods as those made using sequences of processes that extract substances from foods and alter them with chemicals。In order to formulate the final product,ultra processed foods are characteristically designed to be cheap,tasty and convenient。Examples include soft drinks and candy,package snacks and pastries,ready to heat products and reconstituted meat products。Studies have linked consumption of ultra processed foods which are often high in salt,sugar and fat weight gain and an increased risk of chronic diseases,even after adjusting for the amount of salt,sugar and fat in the diet,while the mechanisms behind these associations are not fully understood,montero argues that the existing evidence is sufficient to justify discouraging consumption of ultra processed foods in dietary recommendations and government policies。

  Questions 9to11 are based on the passage you have just heard。

  Question 9,what question is said to have recently stirred debate?

  Question 10,how does the system developed by montero and colleagues classify foods?

  Human creativity benefits from constraints。According to psychologists,when you have less to work with,you actually begin to see the world differently。It constraints。You dedicate your mental energy acting more resourcefully when challenged you figure out new ways to be better the most successful creative people know that constraints give their minds the impetus to leap higher。People who invent new products are not limited by what they dont have or cant do。They leverage their limitations to push themselves even further。Many products and services are created because the founders saw a limitation in what they use。They created innovation based on what was not working for them at the moment。Innovation is a creative persons response to limitation in a 2015study which examined how thinking about scarcity or abundance influences how creatively people use their resources。Ravi matter at the university of illinois and meng zhu at johns hopkins university found that people simply have no incentive to use whats available to them in novel ways。When people face scarcity,they give themselves the freedom to use resources in less conventional ways because they have to obstacles can broaden your perception and open up your thinking processes,consistent constraints,help you improve at connecting unrelated ideas and concepts。Marissa meyer,former vice president for search products and user experience at google。Once wrote in a publication on bloomberg constraints,shape and focus problems and provide clear challenges to overcome。Creativity thrives best and constraint。

  Recording one different people use different strategies for managing conflicts。These strategies are learned in childhood。Usually we are not aware of how we act in conflict situations。We just do whatever seems to come naturally,but we do have a personal strategy and because it is learned,we can always change it by learning new and more effective ways of managing conflicts。When you get involved in a conflict,there are two major concerns you have to take into account,achieving your personal goals and keeping a good relationship with the other person,how important your personal goals are, how important the relationship is to you affect how you act in a conflict。Given these two concerns,five styles of managing conflicts can be identified when the turtle turtles withdraw into their shells to avoid conflicts。They give up their personal goals and relationships。They believe it is easier to withdraw from a conflict than to face it。Two,the shark sharks try to overpower opponents by forcing them to accept their solution to the conflict they seek to achieve their goals at all costs。Sharks assume that conflicts are settled by one person winning and one person losing。Winning gives sharks a sense of pride and achievement losing gives them a sense of weakness,inadequacy and failure。Three,the teddy bear。Teddy bears want to be accepted and liked by other people。They think that conflict should be avoided in favor of harmony and believe that conflicts cannot be discussed without damaging relationships。They give up their goals to preserve the relationship for the fox foxes are moderately concerned with their own goals and about their relationships,with other people。They give up part of their goals and persuade the other person in a conflict to give up part of his goals。They seek a solution to conflicts where both sides gain something5,the owl owls view conflicts as problems to be solved。They see conflicts as improving relationships by reducing tension between two people。They try to begin a discussion that identifies the conflict as a problem by seeking solutions that satisfy both themselves and the other person。Owls maintain the relationship。Owls are not satisfied until a solution is found that achieves their own goals and the other persons goals。And they are not satisfied until the tensions and negative feelings have been fully resolved。

  Questions 16to18 are based on the recording you have just heard。

  Question 16。Why does the speaker say strategies for managing conflicts can always be changed?

  Question 17,what is said to affect the way one acts in a conflict?

  Question 18 of the five styles the speaker discusses which views conflicts as problems to be solved?

  Recording two,the genetic code of all1.5million known species of animals and plants living on earth will be mapped to help save species from extinction and boost human health。Scientists hope that cracking the genetic code of plants and animals could help uncover new treatments for infectious diseases。Slow aging improve crops in agriculture create new bio materials in britain,organizations including the natural history museum,the royal botanic gardens,a queue and the welcome sanger institute have joined forces to sequence britains 66,000 species of animals and plants dubbed the darwin tree of life project。It is expected to take 10 years and cost£100 million once completed。All the information will be publicly available to researchers。Many scientists believe that earth has now entered the 6th mass extinction with humans creating a toxic mix of habitat loss,pollution and climate change,which has already led to the loss of at least 77 species of mammals and 140 types of birds。Since1500,it is the biggest loss of species since the dinosaurs were wiped out 66 million years ago。Scientists say that sequencing every species will revolutionize the understanding of biology and evolution,bolster efforts to conserve as well as protect and restore biodiversity。Doctor tim littlewood,head of life sciences department at the natural history museum said whether you are interested in food or disease,the history of how every organism on the planet has adapted to its environment is recorded in its genetic makeup,how you then harness that is dependent on your ability to understand it。We will be using modern methods to get a really good window on the present and the past。And course,a window on the past gives you a prospective model on the future。Sir jim smith,director of science at welcome said,try as I I cant think of a more exciting,more relevant,more timely or more internationally inspirational project。Since1970,humanity has wiped out60%of animal populations about 23,000of80,000 species surveyed are approaching extinction。We are in the midst of the 6th great extinction events of life on our planet which not only threatens wildlife species,but also imperils the global food supply。As scientists,we all realise we desperately need to catalogue life on a fragile planet。Now I think were making history。

  Questions19to21 are based on the recording you have just heard

  question 19.what do scientists hope to do by cracking the genetic code of plants and animals?

  Question 20,what do many scientists believe with regard to earth?

  How does sir jim smith,director of science at welcome describe the darwin tree of life project。John dunn,the english poet wrote in the 17th century,no man is an island entire of itself。Every man is a piece of the continent,a part of the main。Now a british academic has claimed that human individuality is indeed just an illusion,because societies are far more interconnected at a mental,physical and cultural level than people realize。In his new book,the self delusion。Professor tom oliver,a researcher in the ecology and evolution group at the university of reading argues there is no such thing as self。 And not even our bodies are truly us.

The sonora valley just below it is equally stunning. The transformation commenced in a town hall meeting in spring 2008 over 10 years ago. Now when an overwhelming majority of neighbors voted in favor of motion, 836, this legislative proposal essentially set out to harmonize the aesthetic appearance of all the houses in berkton. The idea was that if all the properties looked a certain way with shared design features, then the village as a whole would look more beautiful. It worked, it certainly did.

  Im looking now at a before and after photo and the change is truly remarkable. Its hard to believe its the same place. How do the neighbours feel now? Great pride.

  I would say.

  But what about the multitudes of visitors now crowding the streets? Is everyone happy about that?

  The tourists we receive are a blessing as they have completely revitalized our local economy. Every visitor is warmly welcome.

  Questions 5 to 8 are based on the conversation you have just heard.

  Question 5, what is the question the woman asked mister grimm after the introduction?

  Question 6, what do we learn about burkton of 10 years ago?

  Question 7, what resulted from the passing of the legislative proposal motion 836.

  Question 8, why does the man say the tourists are a blessing to bergen? Passage one,

  researchers in the us have created a remote controlled robot that is so small. It can walk on the top of aus penny in research published in the journal science, robotics. A team at northwestern university said the crab like robot is 0.5 millimeters wide. Researchers described it as the smallest ever remote controlled walking robot. The tiny robot can bend, twist, crawl, walk, turn and even jump without the use of complex hardware or special power. The engineers said this is because the robot is powered by the elastic property of its body. To construct the robot, the researchers used a shape memory alloy material that transforms to its remembered shape when heated using a laser, the team is able to heat the robot at specific parts of its body, causing it to change shape as the robot deforms and goes back to its original shape. It creates movement from one place to another, because these structures are so tiny, the rate of cooling is very fast. Project lee, professor john a rogers said, in fact, reducing the sizes of these robots allows them to run faster. While the research is still in the exploratory phase, the team believes that technology could lead to micro sized robots that can perform practical tasks. In tightly confined spaces, you might imagine micro robots as agents to repair or assemble small structures or machines in industry or a surgical assistance to clear clogged arteries to stop internal bleeding or to eliminate cancerous tumors all in minimally invasive procedures. Rogers said.

  Questions 9 to 11 are based on the passage you have just heard.

  Question 9, what does the passage say about a team of researchers at northwestern university?

  Question 10, what did the researchers say about the robot they created?

  Question 11, what do the researchers expect their robots to do in the future?

  Passage two, I dont want to boast or anything, but I have always considered myself something of an elite sleeper given the opportunity, I will sleep for marathon stretches and condose through the most extreme situations on one very rough ferry crossing on the route to the isles of silly. For example, my traveling companion spent the entire 3 hour ride throwing up in the bathroom while I dozed happily on a plastic chair. Unfortunately, it has come to my attention that I am not an elite sleeper. After all. It seems I am just lazy because elite sleepers are defined as the approximately 3% of the population who are biologically programmed to need less sleep than the rest of us. According to a study that came out in march, elite sleepers have rare genetic changes, which means they can sleep fewer hours than mere mortals without any risk of cognitive decline, it may not be possible to change your own genes, but can you train yourself to need less sleep? Is there a non biological way to reach elite sleeper status? I have spent the past year trying to answer that question, not for fun, I should add because having a baby has severely disrupted my sleep for which I still have a great passion for a while. I assumed id be forced to become one of those people who jump out of bed at the crack of dawn. After a year of tough scientific study, however, I have discovered being forced to get up early in the morning is very different from being an early bird.

  Questions 12 to 15 are based on the passage you have just heard.

  Question 12. What does the speaker say she did on her ride to the isles of silly

  Question 13. What do we learn from the passage about elite sleepers?

  Question 14, what has the speaker been trying to find out over the past year?

  Question 15, what has the speaker discovered after a year of tough scientific study?

  Recording one if you read an article about a controversial issue, do you think youd realize if it had changed your beliefs? No one knows your own mind like you do. It seems obvious that you would know if your beliefs had shifted. And yet a new paper in the quarterly journal of experimental psychology suggests that we actually have very poor awareness of our own belief change, meaning that we will tend to underestimate how much weve been swayed. By a convincing article, the researchers recruited over 200 undergraduates across two studies and focused on their beliefs about whether physical punishment of kids is an effective form of discipline. The students reported their initial beliefs about whether physical punishment is an effective way to discipline a child on a scale from one completely disbelief to nine completely believe. Several weeks later, they were given one of two research based text to read. Each was several pages long and either presented the arguments and data in favor of physical punishments or against it. After this, the students answered some questions to test their comprehension and memory of the text. Then the students again scored their belief in whether physical punishment is effective or not. Finally, the researchers asked them to recall what their belief had been at the start of the study. The students belief about physical punishment changed when they read a text that argued against their own initial position. Crucially, the memory of their initial belief was shifted in the direction of their new belief. In fact, their memory was closer to their current belief than their original belief. The more their belief had changed, the larger this memory bias tended to be suggesting the students were relying on their current belief to deduce their initial belief, the memory bias was unrelated to the measures of how well theyd understood or recalled the text, suggesting these factors didnt play a role in memory of initial belief or awareness of belief change. The researchers concede that this research was about changes to mostly moderate beliefs. Its likely the findings would be different in the context of changes to extreme or deeply held beliefs. However, our beliefs on most topics are in the moderate range. And as we go about our daily lives reading informative material, these intriguing findings suggest we are mostly ignorance of what we just read has updated and altered our own position. Questions.

  16 to 18 are based on the recording you have just heard.

  Question 16. What does a new paper in the quarterly journal of experimental psychology suggest?

  Question 17, what happened when the students read a text that argued against their own initial position?

  Question 18, what did the researchers concede concerning their findings according to as the american population grows?

  So does the number of american moms recording to as the american population grows? So does the number of american moms, but more than a century after mothers day became an official holiday. Even as that number increases, the share of the american population who are mothers is at the lowest point in 1/4 century. Its frequently noted that fertility rates are falling sharply in richer countries, but the less observed consequence of this trend is that a decline in births can also mean a decline in motherhood in general. According to my analysis of data from the census bureau, the decline of american motherhood is real occurring very quickly and may continue for some time yet. Not only are moms making up less of the population, but their characteristics are changing too. And in a way that might be linked to their proportional decline, moms today tend to be older than in the past. Just looking at recent years, the change in age specific birth rates has been drastic. In just the past few years, the peak childbearing age range for american women has advanced from that of 25 to 29 that To 34. Meanwhile childbearing among women under 20 has fallen by half or more. While childbearing among women 35 and older is rising. One positive consequence of this age shift is that a larger proportion of new mothers are economically prepared to raise children less positively. However, many women find that as they age, they cant have as many kids as they would like. Plus having children later in life can increase the risk of health complications. These finer points aside, one major consequence of the older moms trend is that fewer years of a womans life are spent as a mother. This means that at any given time, a larger share of women and thus of the whole population will report not having children in government surveys. In other words, later motherhood means less motherhood, even as motherhood rates decline, mothers day will endure. In fact, despite the demographic shift, retail spending on the holiday appears to be rising. It is hard to say if mothers day spending is rising more than one would expect, given that the american population keeps growing. But one factor might be that the proportion of women who are the mothers of adult children is rising. Those adult children may spend more generously when it comes to celebrating the moms. They no longer live with.

  Questions, 19 to 21 are based on the recording. You have just heard.

  Question 19. What does the speaker conclude from her analysis of the census bureaus data?

  Question 20. What does the speaker say is a positive consequence of the age shift in childbearing?

  Question 21. What might be one explanation for the rise in retail spending on mothers day?

  Recording three. Since nasa published a paper in 1989, claiming that house plants can soak up pollution and toxic chemicals, businesses and homeowners have increasingly invested in greenery to help clean their air. But a new analysis suggests it could actually take more than 1,000 plants per square meter to gain a benefit any greater than simply opening a couple of windows. The problem lies in the fact that NASA conducted their tests in sealed containers that do not simulate the conditions in most peoples homes or offices. The space agency was primarily concerned about keeping the air fresh for astronauts cut off in biosphere or space stations and helping to combat sick building syndrome, which had become a problem due to the super insulated and energy efficient officers of the late 1970s. By the early 1980s, workers regularly complained of skin rashes, sleepiness, headaches and allergies as they breathed in toxic chemicals from paints and plastics. Nasa found that certain plants could remove chemicals from the air. And even today, garden centers recommend the plants for air cleaning properties. However, a new evaluation of dozens of studies spanning 30 years found that house plants in a normal environment have little impact. In fact, natural ventilation is far better at cleaning the air. The researchers also calculated the clean air delivery rates for plants in the studies they analyzed and found that the rate at which plants dispersed the compounds was well below the usual rates of air exchange in a normal building caused by the movements of people coming and going opening doors and windows. Many of the studies did show a reduction in the concentration of volatile organic compounds over time, which is likely why people have seized on them to praise the air purifying virtues of plants. But the researchers calculation showed it would take 10 to 1,000 plants per square meter of floor space to compete with the air cleaning capacity of a buildings, air handling system, or even just a couple of open windows in a house. In contrast, NASA sealed experiment recommended one pot plants per 100 square feet. This is certainly an example of how scientific findings can be misleading or misinterpreted over time. But its also a great example of how scientific research should continually re examine and question findings to get closer to the ground truth of understanding whats actually happening.

  Questions 22 to 25 are based on the recording. You have just heard question 22. What does nas as 1989 paper? Claim house plants can do.

  Question 23. What is said to be the problem with nas as study reported in its 1989 paper?

  Question 24. What is the finding of a new evaluation of dozens of studies spanning 30 years?

  Question 25. What does NASA sealed experiment recommendation exemplify in scientists pursuit of truth?

  Thank you for meeting with me,steven at such short notice。

  not a problem,margaret。Now please give me some good news。Have you agreed to my last proposal?

  I have indeed and I wish to sign the agreement pending one small change to be made to the contract。

  Margaret,we have been through this for almost a year now back and forth making alterations。Are you sure you want to make a sponsorship deal for your clients or not?I ask this because frankly,some people at my end are running out of patience。I understand your concerns。

  but as im sure you understand,we hold our clients best interests to be of the utmost concern。We therefore comb through the fine details of all contracts。Rest assured we all appreciate your firms patience。

  Fine。So what changes do you wish to make?

  Essentially,we would like the new deal to exclude the middle east。

  Thats all the middle east。

  Why my client has a couple of other perspective marketing deals from companies in the middle east。Those offers should they materialize would exclusively employ my clients image in the middle east only。Therefore,in order to avoid any conflict,we would need to ensure that both marketing campaigns do not overlap geographically。

  What business sector in the middle east are we talking about here?

  Real estate.

  that should be okay then so long as the product is very different from our food and beverage market,there should be no conflict of interest。Nevertheless,I will have to run this through my people。I dont foresee any problem though,the middle east is a negligible market for us,but I still need to check this with a couple of departments。

  Next,we have a special science related news story。Paula hancock is at the denver observatory。Paula,what is the big story over there?Hi.john.All the astronomers on site here are very excited。In fact,space enthusiasts all across north america and the rest of the northern hemisphere will be congregated on mountain tops tonight to watch the night sky。

  Whats the big event?Is there an eclipse happening soon?

  Tonight the earth will come into close proximity with the oppenheimer comet。It is the closest our planet has been to such a phenomenon in over 100years。For this reason。It is expected that thousands of people will gaze up at the sky tonight in order to see this formidable object。

  How far away is this common?Will people be able to see it with the naked eye?

  The oppenheimer comet will still be millions of miles away on the edge of our galaxy。But nevertheless,this is a relatively close distance,close enough for people to observe in good detail through a telescope。People will only see a blur without one。However that does not mean one needs professional equipment。Even the most ordinary of telescopes should be conducive for people to observe and wonder at this flying object。

  Many of our viewers will be wondering how they too can take part in this once in a lifetime event。Where will this comment be in the sky?How can people find it?

  The comet will be almost exactly due north at60°above the equator。However,finding the comet is indeed very tricky and scientists here have told me there are plenty of phone apps that will facilitate this。

  dietary guidelines form the basis for nutrition advice and regulations around the world。While there is strong scientific consensus around most existing guidelines。One question has recently stirred debate。Should consumers be warned to avoid ultra processed foods?Two papers published today in the american journal of clinical nutrition outline the case for and against using the concept of ultra processed foods to help inform dietary guidelines beyond conventional food classification systems。The authors,carlos monteiro of the university of sao paulo and arna ostrich of novo nordisk foundation。Well discuss the issue in a live virtual debate。August14th,during nutrition,2024live online。The debate centers around a system developed by monteiro and colleagues that classifies foods by their degree of industrial processing,ranging from unprocessed to ultra processed。The system defines ultra processed foods as those made using sequences of processes that extract substances from foods and alter them with chemicals。In order to formulate the final product,ultra processed foods are characteristically designed to be cheap,tasty and convenient。Examples include soft drinks and candy,package snacks and pastries,ready to heat products and reconstituted meat products。Studies have linked consumption of ultra processed foods which are often high in salt,sugar and fat weight gain and an increased risk of chronic diseases,even after adjusting for the amount of salt,sugar and fat in the diet,while the mechanisms behind these associations are not fully understood,montero argues that the existing evidence is sufficient to justify discouraging consumption of ultra processed foods in dietary recommendations and government policies。

  Recording one different people use different strategies for managing conflicts。These strategies are learned in childhood。Usually we are not aware of how we act in conflict situations。We just do whatever seems to come naturally,but we do have a personal strategy and because it is learned,we can always change it by learning new and more effective ways of managing conflicts。When you get involved in a conflict,there are two major concerns you have to take into account,achieving your personal goals and keeping a good relationship with the other person,how important your personal goals are, how important the relationship is to you affect how you act in a conflict。Given these two concerns,five styles of managing conflicts can be identified when the turtle turtles withdraw into their shells to avoid conflicts。They give up their personal goals and relationships。They believe it is easier to withdraw from a conflict than to face it。Two,the shark sharks try to overpower opponents by forcing them to accept their solution to the conflict they seek to achieve their goals at all costs。Sharks assume that conflicts are settled by one person winning and one person losing。Winning gives sharks a sense of pride and achievement losing gives them a sense of weakness,inadequacy and failure。Three,the teddy bear。Teddy bears want to be accepted and liked by other people。They think that conflict should be avoided in favor of harmony and believe that conflicts cannot be discussed without damaging relationships。They give up their goals to preserve the relationship for the fox foxes are moderately concerned with their own goals and about their relationships,with other people。They give up part of their goals and persuade the other person in a conflict to give up part of his goals。They seek a solution to conflicts where both sides gain something5,the owl owls view conflicts as problems to be solved。They see conflicts as improving relationships by reducing tension between two people。They try to begin a discussion that identifies the conflict as a problem by seeking solutions that satisfy both themselves and the other person。Owls maintain the relationship。Owls are not satisfied until a solution is found that achieves their own goals and the other persons goals。And they are not satisfied until the tensions and negative feelings have been fully resolved。

  Recording two,the genetic code of all1.5million known species of animals and plants living on earth will be mapped to help save species from extinction and boost human health。Scientists hope that cracking the genetic code of plants and animals could help uncover new treatments for infectious diseases。Slow aging improve crops in agriculture create new bio materials in britain,organizations including the natural history museum,the royal botanic gardens,a queue and the welcome sanger institute have joined forces to sequence britains 66,000 species of animals and plants dubbed the darwin tree of life project。It is expected to take 10 years and cost£100 million once completed。All the information will be publicly available to researchers。Many scientists believe that earth has now entered the 6th mass extinction with humans creating a toxic mix of habitat loss,pollution and climate change,which has already led to the loss of at least 77 species of mammals and 140 types of birds。Since1500,it is the biggest loss of species since the dinosaurs were wiped out 66 million years ago。Scientists say that sequencing every species will revolutionize the understanding of biology and evolution,bolster efforts to conserve as well as protect and restore biodiversity。Doctor tim littlewood,head of life sciences department at the natural history museum said whether you are interested in food or disease,the history of how every organism on the planet has adapted to its environment is recorded in its genetic makeup,how you then harness that is dependent on your ability to understand it。We will be using modern methods to get a really good window on the present and the past。And course,a window on the past gives you a prospective model on the future。Sir jim smith,director of science at welcome said,try as I I cant think of a more exciting,more relevant,more timely or more internationally inspirational project。Since1970,humanity has wiped out60%of animal populations about 23,000of80,000 species surveyed are approaching extinction。We are in the midst of the 6th great extinction events of life on our planet which not only threatens wildlife species,but also imperils the global food supply。As scientists,we all realise we desperately need to catalogue life on a fragile planet。Now I think were making history。

  Questions19to21 are based on the recording you have just heard

  question 19.what do scientists hope to do by cracking the genetic code of plants and animals?

  Question 20,what do many scientists believe with regard to earth?

  How does sir jim smith,director of science at welcome describe the darwin tree of life project。John dunn,the english poet wrote in the 17th century,no man is an island entire of itself。Every man is a piece of the continent,a part of the main。Now a british academic has claimed that human individuality is indeed just an illusion,because societies are far more interconnected at a mental,physical and cultural level than people realize。In his new book,the self delusion。Professor tom oliver,a researcher in the ecology and evolution group at the university of reading argues there is no such thing as self。 And not even our bodies are truly us. Just as Copernicus realized, the earth is not the center of the universe. Professor Oliver said society urgently needs a Copernican like revolution to understand people are not detached beings, but rather part of one connected identity, a significant milestone in the cultural evolution of human minds was the acceptance that the earth is not the center of the universe, the so called Copernican revolution, he writes, however, we have one more big myth to dispose of that we exist as independent selves at the center of a subjective universe. You may feel as if you are an independent individual acting autonomously in the world that you have unchanging inner self that persists throughout your lifetime, acting as a central anchor point with the world changing around you. This is the illusion I seek to tackle. We are intimately connected to the world around us. Professor Oliver argues there are around 37 trillion cells in the body, but most have a lifespan of just a few days or weeks. So the material us is constantly changing. In fact, there is no part of your body that has existed for more than 10 years. Since our bodies are essentially made anew every few weeks, the material in them alone is clearly insufficient to explain the persistent thread of an identity. Professor Oliver claims that individualism is actually bad for society only by realizing we are part of a bigger Entity. Can we solve pressing environmental and societal problems through selfish over consumption? We are destroying the natural world and using non renewable resources at an accelerating rate. We are at a critical crossroads as a species where we must rapidly reform our mindset and behavior to act in less selfish ways. He said so lets open our eyes to the hidden connections all around us.

  Questions, 22 to 25 are based on the recording you have just heard.

  Question 22. What is indeed just an illusion according to professor Tom Oliver?

  Question 23. What does professor Tom Oliver think of the idea that we exist as independent selves at the center of a subjective universe?

  Question 24. Why does professor Tom Oliver claim that the material us is constantly changing?

  Question 25. How can we solve pressing environmental and societal problems? According to professor Tom Oliver.

  社會實踐和學習同樣重要

  There is a growing awareness of the equal importance ofsocial practice and academic learning in todays world.Some believe that social practice is thekey to success,whileothers arguethat it is not compulsory for everyone toengage in.Personally,I find the former view morereason-able.

  Firstly,social practice is essential for students.It allows themto apply what they have learned in the classroom to real-lifescenarios,enhancing their understanding and reinforcingtheir knowledge.For example,participating in internships orvolunteer work can provide students with valuable insightsinto their chosen field and help them develop practical skillsthat cannot be learned from textbooks.Secondly,in theworkplace,employers value individuals who can effectivelycollaborate,communicate,and adapt to different situations.Lastly,in daily life,social practice enables individuals to in-teract effectively with others,resolve conflicts,and make in-formed decisions.

  In conclusion,social practice and academic learning are ofequal importance in todays world.By recognizing and em-bracing the value of both,we can foster a society thatvaluesknowledge,practical skills,and social responsibility.

  The importance of acquiring the basic knowledge

  As we all know,mastering good basic knowledge is an important step that every student must go through in the learning process,and it is crucial for students to master any subject.Therefore,we should fully realize the importance of mastering basic knowledge.Heres why.

  First of all,without a solid foundation,it is impossible to understand more profound theories of knowledge,and it is impossible to advance to a higher level.Take English learning as an example,if we do not have a solid grasp of English grammar and vocabulary,we will not be able to effectively understand literary works and understand higher-level English concepts.Second,just as a building needs a solid foundation to support its structure,our academic success requires a solid grasp of the basics.From personal experience,I clearly remember a deep understanding of foundatiohaf concepts paving the way for my success in challenging courses.Finally,no foundation,no progress.For the system of knowledge is interlinked,without a solid foundation,the knowledge systemwill be full of holes.

  Therefore,I think it is very important for students to get a good basic knowledge.

  With their valuable skills and experiences,elderly people can continue to make significant contributions to society.This view is accepted by more and more citizens as they wit-ness firsthand the capabilities of these experienced individ-uals.

  First of all,the older generation,especially highly skilled workers,is still irreplaceable for jobs that require extensive skills and expertise.Without them,it is highly possible that work quality and efficiency will be seriously affected.In ad-dition,these senior citizens play a significant role in trainingor cultivating the young generation by passing down their valuable skills and experiences.Young people,benefiting from this mentorship,can directly contribute to their organi-zations and country.Finally,the elderly can even be part of think tanks,offering precious advice or suggestions to the management teams of firms or to the government,thus pro-moting development.

  Therefore,recognizing the significance of elderly people and encouraging their active participation in society is cru-cial,rather than merely viewing them as individuals who should retire from active life.

  憑借他們寶貴的技能和經驗,老年人可以繼續為社會做出重大貢獻。這一觀點被越來越多的公民所接受,因為他們親眼目睹了這些有經驗的人的能力。

  首先,對于需要廣泛技能和專業知識的工作,老一代,特別是高技能工人,仍然是不可替代的。沒有他們,工作質量和效率很可能會受到嚴重影響。此外,這些老年人通過傳遞寶貴的技能和經驗,在培訓或培養年輕一代方面發揮著重要作用。受益于這種指導的年輕人可以直接為他們的組織和國家做出貢獻。最后,老年人甚至可以成為智庫的.一員,為企業的管理團隊或政府提供寶貴的意見或建議,從而促進發展。

  因此,認識到老年人的重要性并鼓勵他們積極參與社會是至關重要的,而不是僅僅把他們視為應該退出積極生活的個人。

  Nowadays,parents are increasingly aware that allowing kids more freedom to explore and learn on their own helps foster their independence and boost their confidence.On social media,it is common to see many youngsters who are independent and confident,a trait often attributed to auton-omy in their childhood development.

  The importance of autonomy can be explained as follows.Firstly,children who are given more freedom can cultivate critical thinking skills,problem-solving abilities,and resil-ience.As they navigate challenges and learn from their mis-takes,children become more self-reliant and resourceful,which in turn bolsters their confidence and self-esteem.Second,granting autonomy to children nurtures their cre-ativity and curiosity.When children are allowed to pursue their passions,they are more likely to discover new talents and develop a lifelong love of learning.If they graduate and enter the workplace in the future,they are more likely to create a good impression on their boss and thus are more likely to receive a pay raise or a promotion quickly.

  To sum up,the increasing awareness of the importance ofautonomy in childhood development is crucial.It not onlyhelps foster childrens independence and confidence but also contributes to their overall well-being and future careersuccess.

  自主性的重要性可以解釋如下。首先,給予更多自由的孩子可以培養批判性思維能力、解決問題的能力和應變能力。當他們應對挑戰并從錯誤中吸取教訓時,孩子們變得更加自立和足智多謀,這反過來又增強了他們的信心和自尊。第二,給予孩子自主權可以培養他們的創造力和好奇心。當孩子們被允許去追求他們的激情時,他們更有可能發現新的才能,并培養對學習的終身熱愛。如果他們將來畢業并進入職場,他們更有可能給老板留下好印象,從而更有可能迅速獲得加薪或晉升。

  總之,越來越多的人意識到自主在兒童發展中的重要性是至關重要的。它不僅有助于培養孩子的獨立性和自信心,而且有助于他們的整體福祉和未來的事業成功。

  作文1:

  The importance of acquiring the basic knowledge

  As we all know,mastering good basic knowledge is an important step that every student must go through in the learning process,and it is crucial for students to master any subject.Therefore,we should fully realize the importance of mastering basic knowledge.Heres why.

  First of all,without a solid foundation,it is impossible to understand more profound theories of knowledge,and it is impossible to advance to a higher level.Take English learning as an example,if we do not have a solid grasp of English grammar and vocabulary,we will not be able to effectively understand literary works and understand higher-level English concepts.Second,just as a building needs a solid foundation to support its structure,our academic success requires a solid grasp of the basics.From personal experience,I clearly remember a deep understanding of foundatiohaf concepts paving the way for my success in challenging courses.Finally,no foundation,no progress.For the system of knowledge is interlinked,without a solid foundation,the knowledge systemwill be full of holes.

  Therefore,I think it is very important for students to get a good basic knowledge.

  With their valuable skills and experiences,elderly people can continue to make significant contributions to society.This view is accepted by more and more citizens as they wit-ness firsthand the capabilities of these experienced individ-uals.

  First of all,the older generation,especially highly skilled workers,is still irreplaceable for jobs that require extensive skills and expertise.Without them,it is highly possible that work quality and efficiency will be seriously affected.In ad-dition,these senior citizens play a significant role in trainingor cultivating the young generation by passing down their valuable skills and experiences.Young people,benefiting from this mentorship,can directly contribute to their organi-zations and country.Finally,the elderly can even be part of think tanks,offering precious advice or suggestions to the management teams of firms or to the government,thus pro-moting development.

  Therefore,recognizing the significance of elderly people and encouraging their active participation in society is cru-cial,rather than merely viewing them as individuals who should retire from active life.

  憑借他們寶貴的技能和經驗,老年人可以繼續為社會做出重大貢獻。這一觀點被越來越多的公民所接受,因為他們親眼目睹了這些有經驗的人的能力。

  首先,對于需要廣泛技能和專業知識的工作,老一代,特別是高技能工人,仍然是不可替代的。沒有他們,工作質量和效率很可能會受到嚴重影響。此外,這些老年人通過傳遞寶貴的技能和經驗,在培訓或培養年輕一代方面發揮著重要作用。受益于這種指導的年輕人可以直接為他們的組織和國家做出貢獻。最后,老年人甚至可以成為智庫的一員,為企業的管理團隊或政府提供寶貴的意見或建議,從而促進發展。

  因此,認識到老年人的重要性并鼓勵他們積極參與社會是至關重要的,而不是僅僅把他們視為應該退出積極生活的個人。
