（3）The Biochemistry of Hibernation
The biochemistry of hibernation may help save human lives．During the long cold winter many of us struggle to keep warm while we wait for the warmth of spring．But there are some animal going into a deep sleep during winter． When an animal is hibernating in this way，its body temperature falls to nearly freezing．The organs（器官）of the animal's body almost stop working．The heart beats only a few times a minute．For example，the ground squirrel's heartbeat during hibernation slows from its normal 350 beats each minute to only 3 or 4． Hibernating animals can lose as much as one half of their body weight during the sleep，and the body's need for food is sharply reduced．No hibernating animal sleeps all winter without waking from time to time．Hibernating squirrels awaken about 15 days．Bats awaken every 30-40 days．Scientists believe that these periods of waking and sleeping are controlled by a substance（物質(zhì)）in the blood called HIT（hibernation inducing trigger冬眠誘發(fā)劑）．Scientists have found that by putting small amounts of this substance into the brain of an animal，the animal's heartbeat begins to slow and the body temperature begins to fall．This was true even for animal that do not hibernate，such as monkeys．When HIT was put into a monkey's brain，its heartbeat slowed as much as 50 ％． The body temperature fell several degrees，and its interest in food disappeared．Doctors believe that HIT，when it is better understood，might be used during operations on the heart or other parts of the body．It could reduced the body'stemperature and slow the heartbeat to reduce bleeding．The effect of HIT on a person'sinterest in food also might be used in helping those who want to lose weight．And HIT might be used in space travel．An astronaut sent to a distant planet or star might be able to hibernate for most of the trip，waking only when necessary．（Words：330 Minutes：5．5）1．During hibernation the ground squirrels heart beat鷂___ ．
A．falls several times鶥．slows from 350 to 120 beats a minute
C．goes up from 3 or 4 to 350 beats a minute鶧．reduces from its normal 350to 3or 4 beats a minute
2．During the winter sleep，hibernating animals can lose鷂___ of their body weight．
A．1／2鶥．1／3 C．2／3鶧．1／4
3．What effect does the substance HIT have on hibernating animals？
A．It has a chemical effect on them．鶥．It has a bad effect on them．
C．It has an effect on the rising of their body temperature．
D．It can control the periods of their waking and sleeping．
4．Doctors believe that HIT might be used during operations because鷂___ ．
A．it could make the patient sleep
B．it could reduce the body's temperature and heartbeats to reduce bleeding
C．it could make the sick feel less pain D．it could keep the sick awake during the operation
5．HIT might be used in space travel ____ ．
A．to make the travel faster鶥．to make the astronaut hibernate for most of the trip
C．to save fuel（燃料）鶧．to make the spaceship come back on time
