Unit 2 Working the land
Part One: Teaching Design (第一部分：教學設計)
1． A sample lesson plan for reading
(Working the land)
Aims
To help students develop their reading ability.
To help students learn about working the land.
Procedures
I. Warming up
Warming up by questioning
Hello, everyone. We shall read about man who works the land today. Have you ever grown any plants? If not, what kind of plant would you like to grow? How will you grow it?
(For reference: Mr. Li, I worked with my father in the rice field last year. We grow hybrid rice and use animal wastes to make the soil rich.)
Has anyone of you ever been to the countryside? What did you do there?
(For reference: I went to Chuankou the day before yesterday. It is a small mountain village 75 li north of Beijing. I went there to visit my uncle’s family. I like that small beautiful village very much. )
Who are from a farmer’s family? What do you know about farming?
(For reference: Mr. Li, Dou Jun and I are from a farmer’s family in our class. We grow wheat and raise pigs on our farms. And both of our family are going to expand the area of fields this year. )
Warming up seeing and listening
Boys and girls, I shall show you some photos of farming first. Look at this one. What are these ppeople doing in the fields? Yes, it is spring and they are planting rice. Lots of people in the world live on rice. I think you like eating rice, too.
Planting rice
Here is another photo about farming. The man driving the tractor in the photo is plowing the land to prepare for the planting. He does not grow rice there. What kind of crop is he going to plant here?
Plowing the land
This photo is interesting. The woman farmer from Tibet is harvesting her crops not in the open field but in a plastic house. For generations, the people in Tibet Autonomous Region, have farmed the land using traditional methods. But in recent years, things have begun to change. All the farmers admitt the new ways are better.
Indoor harvesting
II. Pre-reading
1. Questioning and answering
Rice is main food in South China. What do you think would happen if tomorrow there was suddenly no rice to eat?
(For reference: Then the south people would have to change their eating habit. They could turn to potatoes, wheat flour, cow and sheep cheese, cabbage, onions and garlic for food. They are the bases of the traditional food in North China. )
If you had the chance to do one thing to help end hunger in the world, what would you do?
(For reference: I would try to end hunger by popularizing the advanced farming techniques. Modern techniques could be introduced to increase the rice output, and expand the area of fields.)
2. Giving background information about Professor Yuan Longping
Have you ever heard of a man called Professor Yuan Longping? Would anyone of you tell the class something about him?
(For reference: Professor Yuan Longping is a Chinese agricultural scientist. Professor Yuan's breakthrough scientific achievement led to the world's first successful and widely grown hybrid rice varieties, revolutionizing rice cultivation in China and tripling production over a generation. His approach to rice breeding then spread internationally throughout Asia and to Africa and the Americas, providing food for tens of millions and leading to his becoming known as the "Father of Hybrid Rice."
III. Reading
1. Reading aloud to the recording
Comprehension-understanding what you are reading-is important. To read in thought groups is an easy, yet effective, way of improving reading comprehension. Now turn to page 9 and read aloud to the recording of the text A PIONEER FOR ALL PEOPLE. Pay attention to the thought groups in the sentences while listening and reading aloud.
2. Reading and underlining
Read the text again and underline all the collocations in the passage. You are asked to copy them to your notebook after class as homework.

IV. Closing down
Closing down by doing exercises
In the last five minutes let’s do the comprehension exercises on page 10. Check your answers against your neighbour’s when you have finished.
Closing down by having a dictation
To end the period you will take a dictation. It is about Yuan Longping, “Father of Super hybrid rice”.
Yuan Longping, China's Most Famous "Farmer"
Yuan came up with the idea of hybridizing rice for the first time in the world in 1960s.
Since then, 50 percent of China's total rice cultivation fields have grown such rice,
which added some 300 billion kilograms to the country's grain output. Furrows grown on his sunburnt face, a slim figure and coiled-up trousers legs would confuse foreign reporters who came to interview the most famous
scientist in China, who would rather be called "a farmer."Indeed, like many Chinese
farmers, Yuan in his 70s and has devoted most of his life growing rice in paddyfields,
but unlike those farmers, he reaps the seed from experimental fields only
for hybridizing rice.

A possible version
Yuan Longping is a man who works the land, does his research and grows hybrid rice. He is an agricultural pioneer to have a high output of rice without expanding the area of fields. He devotes his whole life to finding ways to increase the rice output, to feed both the Chinese and the world people. He is circulating his knowledge so that more farmers can be free from hunger and satisfied with their lives. Yuan cares little about his money and fame. He keeps his time for teaching farmers and growing rice. He wish for more cheep rice for all the people. Yuan Long ping is a great person.
2．Background information on Women of achievement
I. Yuan Longping, China's Most Famous "Farmer"
(2001.02.19 21:59:30 Xin Hua News Service)
CHANGSHA, February 19 (Xinhuanet) -- It says every scientist cherishes a childhood dream indicating his or her future success, but for Yuan Longping, dubbed as "father of hybrid rice," the dream is that he cultivates rice as plump as peanuts, and farmers can relax in the cool shadow of big rice plants.
Yuan, 71, won a 5 million yuan State Supreme Science and Technology Award today, known as the Nobel Prize in China, for his outstanding achievements in breeding high-yield hybrid rice, which has substantially increased China's grain output.
Yuan came up with the idea of hybridizing rice for the first time in the world in 1960s. Since then, 50 percent of China's total rice cultivation fields have grown such rice, which added some 300 billion kilograms to the country's grain output.
Furrows grown on his sunburnt face, a slim figure and coiled-up trousers legs would confuse foreign reporters who came to interview the most famous scientist in China, who would rather be called "a farmer."
Indeed, like many Chinese farmers, Yuan in his 70s and has devoted most of his life growing rice in paddy fields, but unlike those farmers, he reaps the seed from experimental fields only for hybridizing rice.
The urbanite-turned-farmer graduated from Southwest Agriculture College in 1953 has his name related to the world's most advanced agricultural technology. Four minor planets, a listed seed company 's and a science college in China were named after him, which were the first time that a Chinese scientist's name is valued for its intellectual assets.
Is organic food safe?
Yes. Organic food is as safe to consume as any other kind of food. Just as with any kind of produce, consumers should wash before consuming to ensure maximum cleanliness. As cited above, organic produce contains significantly lower levels of pesticide residues than conventional produce. It is a common misconception that organic food could be at greater risk of E. coli contamination because of raw manure application although conventional farmers commonly apply tons of raw manure as well with no regulation whatsoever. Organic standards set strict guidelines on manure use in organic farming: either it must be first composted, or it must be applied at least 90 days before harvest, which allows ample time for microbial breakdown of any pathogens.
By lending his name to the Longping High-tech, a seed company, Yuan obtained a 5 per cent stake, or 2.5 million shares worth 2 million yuan, in the firm.
However, Yuan said his research requires the lifestyle of a farmer, or rather a migrating farmer, as he has conducted extensive research related to the cultivation of new strains of hybrid rice "Super Hybrid Rice" in some 10 provinces.
In the year 1999, more than 300 billion kilograms of grain were increased from about 240 million hectares of hybrid rice, which signified the success of his research. And this made Yuan firmly believe that China can surely feed her 1.2 billion population with her limited cultivated land.
The "Super Rice" yields are 30 percent higher than those of common rice. The record yield of 17,055 kilograms per hectare was registered in Yongsheng County in Yunnan in 1999.
But even after that achievement Yuan won't take a break. He has a dream, more realistic than that of his young age, that popularizing new strains of grain with higher yields around the world, can eliminate starvation on earth.
The UN Food and Agriculture Organization (FAO) has vowed to get involved in the work of spreading the coverage of Yuan's high- yield hybrid rice, which it considers the best way to increase the world's grain output.
How do organic farmers fertilize crops? How do they control pests, diseases, and weeds?
Organic farmers build healthy soils by nourishing the living component of the soil, the microbial inhabitants that release, transform, and transfer nutrients. Soil organic matter contributes to good soil structure and water-holding capacity. Organic farmers feed soil biota and build soil structure and water-holding capacity. Organic farmers feed soil biota and build soil organic matter with cover crops, compost, and biologically based soil amendments. These produce healthy plants that are better able to resist disease and insect predation. Organic farmers' primary strategy in controlling pests and diseases is prevention through good plant nutrition and management. Organic farmers use cover crops and sophisticated crop rotations to change the field ecology, effectively disrupting habitat for weeds, insects, and disease organisms. Weeds are controlled through crop rotation, mechanical tillage, and hand-weeding, as well as through cover crops, mulches, flame weeding, and other management methods. Organic farmers rely on a diverse population of soil organisms, beneficial insects, and birds to keep pests in check. When pest populations get out of balance, growers implement a variety of strategies such as the use of insect predators, mating disruption, traps and barriers. Under the National Organic Rule, growers are required to use sanitation and cultural practices first before they can resort to applying a material to control a weed, pest or disease problem. Use of these materials in organic production is regulated, strictly monitored, and documented. As a last resort, certain botanical or other non-synthetic pesticides may be applied.
The FAO's 1991 statistics show that 20 percent of the world's rice output was yielded from 10 percent of the world's rice fields, which grow hybrid rice.
"If the new strain was sown in the rest of the rice acreage, the present grain output around the world can be more than doubled. This can be a solution to the grain shortage," said the unselfish scientist.
In 1980, Yuan went to the United States at the invitation of the International Rice Research Institute to share his knowledge about the cultivation technology of hybrid rice. He was also employed in 1991 as the chief consultant of FAO to bring his research methods to other countries.
With the help of Chinese scientists, the acreage of hybrid rice in Viet Nam and India increased to 200,000 hectares and 150,000 hectares in 1999, respectively.
The rice research costs time to prove its value. At the age of 43, Yuan cultivated the world's first hybrid rice. At that time the country's grain yield was about 4,500 kilogram per hectare.
"The natural disaster and policy miscarriage further deteriorated starvation in China by then," Yuan recalled tearfully.
This is his motivation to stimulate his research. Largely due to his scientific progress, China's total rice output rose from 5. 69 billion tons in 1950 to 19.47 billion tons last year. The growth rate of rice output far exceeded the population growth speed.
Some people estimate Yuan's actual fortune might amount to more than 100 million yuan (12 million U.S. dollars), making him one of the richest people in China. But he doesn't know for sure himself, for he seems not to care about his own assets than the rice harvest.
Some people asked him to move the focus of his research from improving amounts of hybrid rice to the quality and taste, which would be easier to do. But, the stubborn academician insisted that the amount of hybrid rice's per unit yield still outweighs the quality, for his foremost task is to improve the grain reserve in developing countries.

What is organic farming?
Organic refers to agricultural production systems used to produce food and fiber. All kinds of agricultural products are produced organically, including produce, grains, meat, dairy, eggs, fibers such as cotton, flowers, and processed food products. Organic farming management relies on developing biological diversity in the field to disrupt habitat for pest organisms, and the purposeful maintenance and replenishment of soil fertility. Organic farmers are not allowed to use synthetic pesticides or fertilizers. Some of the essential characteristics of organic systems include: design and implementation of an "organic system plan" that describes the practices used in producing crops and livestock products; a detailed recordkeeping system that tracks all products from the field to point of sale; and maintenance of buffer zones to prevent inadvertent contamination from adjacent conventional fields.
