9.It is difficult for doctors to help a person with a damaged brain.Without enough blood,the brain lives for only three to five minute.More often the doctors can't fix the damage.Sometimes they are afraid to try something to help because it is dangerous to work on the brain.The doctors might make the person worse if he operates on the brain.Dr.Robert White,a famous professor and doctor,thinks he knows a way to help.He thinks doctors should make the brain very cold.If it is very cold,the brain can live without blood for 30 minutes.This gives the doctor a longer time to do something for the brain.
Dr.White tried his idea on 13 monkeys.First he taught them to do different jobs,then he operated on them.He made the monkeys'blood go through a machine.The machine cooled the blood.Then the machine sent the blood back to the monkeys'brains.When the brain's temperature was 10 C,Dr.White stopped the blood to the brain.After 30 minutes he turned the blood back on.He warmed the blood again.After their operations the monkeys were like they had been before.They were healthy and busy.Each one could still do the jobs the doctor had taught them.
28.The biggest difficulty in operating on the damaged brain is thatA.
A.the time is too short for doctors
B.the patients are often too nervous
C.the damage is extremely hard to fix
D.the blood-cooling machine might break down
29.The brain operation was made possible mainly byC.

B.trying the operation on monkeys first
C.lowering the brain's temperature
D.having the blood go through a machine
30.What is the right order of the steps in the operation?B

解答 28-31 ACBA
28.A.细节理解题.根据"It is difficult for doctors to help a person with a damaged brain.Without enough blood,the brain lives for only three to five minute."可知脑部手术的难度在于它的时间必须很短.故选A.
29.C.细节理解题.根据"If it is very cold,the brain can live without blood for 30 minutes."可知大脑可以在温度很低的情况下存活三十分钟.所以脑部手术通常在温度较低的情况下进行.故选C.
30.B推理判断题.由最后一段"He made the monkeys'blood go through a machine.The machine cooled the blood.Then the machine sent the blood back to the monkeys'brains.When the brain's temperature was 10 C,Dr.White stopped the blood to the brain.After 30 minutes he turned the blood back on.He warmed the blood again.After their operations the monkeys were like they had been before."可知首先要冷却血液,然后将冷却的血液输送回大脑,再防止血液流回大脑,最后实施脑部手术.故选B.
31.A.细节理解题.根据"If it is very cold,the brain can live without blood for 30 minutes.This gives the doctor a longer time to do something for the brain."可知把大脑冷却可以延长手术时间,使手术时间延长到三十分钟.故选A.
