COne day when some government officials were rebuilding a barn（谷仓），they found a mouse hole in a corner and used smoke to force the mice inside the hole to come out.A while later they indeed saw mice running out,one after another.Then,everyone thought that all the mice had escapde.But just as they began to clean up,they saw two micesqueezing（挤）out at the mouth of the hole. With some efforts,the mice finally got out. However,it was strange that after they cameout of the hole,they did not run away immediately.Instead,ome chased after the other near the mouth of the hole.It seemed that onewas trying to bite（咬）the tail of the other.Everyone was puzzled,so they stepped nearer to take a look.They realizde that one of the mice was blind and could not see anything,and the other was trying to allow the blind mouse to bite on his tail so that hecould pull the blind one with him to escape.After seeing what happened,everyone was speechless and lost in thought.During the meal time,the group of people sat down in a circle and started to chat about what happened tothe two mice.One serious American official said： “I think the relationship between those two mice was that of king and guard.”The others thought for a while and said：“That was why!”A smart French said： “I think the relationship between those two mice was thatof husband and wife.”Again the others thought for a while,and all felt it made sense.A Japanese said： “I think the relationship between those two mice was that of mother and son.”Once again the others thought for a while,and felt this was more reasonable. So they expressed agreement another time.At that moment,one Chinese asked：“Why did those two mice have to have a certain relationship？ ”Suddenly,the group looked back at the Chinese and remained speechless.The American official,the French and the Japanese who hadspoken earlier all lowered their heads in shame,and did not dare to answer.In fact,the true love is not built on friendship,loyalty or blood relationship.Instead,itis based on no relationship.76.Neither of the two mice ran away immediately because ______.A. one was biting the otherB. the mouth of the hole was too smallC. they were not afraid of smokeD. one was trying to help the blind one
考题
It is clear that ______.A.all the mice came out of the hole easilyB.each of the people understood the relationship differentlyC.the people wanted to kill the mice with smokeD.the people knew one of the mice was blind at first sight
考题
The experiment involves _____ on some mice.
A.to operatingB.operatingC.to be operatingD.in operating

Passage 1
It's one of our common beliefs that mice are afraid of cats. Scientists have long known that even if a mouse has never seen a cat before, it is still able to detect chemical signals released from it and run away in fear. This has always been thought to be something that is hard-wired into a mouse s brain.
But now Wendy Ingram, a graduate student at the University of California, Berkeley, has challenged this common sense. She has found a way to"cure" mice of their inborn fear of cats by infecting them with a parasite, reported the science journal Nature.
The parasite, called Toxoplasma gondii, might sound unfamiliar to you, but the shocking fact is that up to one-third of people around the world are infected by it. This parasite can cause different diseases among humans, especially pregnant women--it is linked to blindness and the death of unborn babies.
However, the parasite's effects on mice are unique. Ingram and her team measured how mice reacted to a cat's urine(尿) before and after it was infected by the parasite. They noted that normal mice stayed far away from the urine while mice that were infected with the parasite walked freely around the test area.
But that's not all. The parasite was found to be more powerful than originally thought—even after researchers cured the mice of the infection. They no longer reacted with fear to a cat's smell,which could indicate that the infection has caused a permanent change in mice's brains.
Why does a parasite change a mouse's brain instead of making it sick like it does to humans?
The answer lies in evolution.
"It's exciting scary to know how a parasite can manipulate a mouse's brain this way," Ingram said. But she also finds it inspiring."Typically if you have a bacterial infection, you go to a doctor and take antibiotics and the infection is cleared and you expect all the symptoms to also go away."
She said, but this study has proven that wrong."This may have huge implications for infectious disease medicine."
The passage is mainly about__________.

Eat to LiveA meager diet may give you health and long life,but it's not much fun-and it might not even be necessary.We may be able to hang on to most of that youthful vigor even if we don't start to diet until old age.Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks.The genetic rejuvenation won't reverse other damage caused by time for the mouse,but could help its liver metabolize drugs or get rid of toxins.Spindler's team fed three mice a normal diet for their whole lives,and fed another three on half-rations.Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old-equivalent to about 70 human years.The researchers checked the activity of 11,000 genes from the mouse livers,and found that-46 changed with age in the normally fed mice.The changes were associated with things like inflammation and free radical production-probably bad news for mouse health .In the mice that had dieted all their lives,27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes."This is the first indication that these effects kick in pretty quickly,"says Huber Warner from the National Institute on Aging near Washington D.C.No one yet knows if calorie restriction works in people as it does in mice,but Spindler is hopeful."There's attracting and tempting evidence out there that it will work,"he says.If it does work in people,there might be good reasons for rejuvenating the liver. As we get ol- der,our bodies are less efficient at metabolizing drugs,for example.A brief period of time of die- ting,says Spindler,could be enough to make sure a drug is effective.But Spindler isn't sure the trade-off is worth it."The mice get less disease,they live longer,but they're hungry,"he says."Even seeing what a diet does,it's still hard to go to a restaurant and say:‘I can only eat half of that.’"Spindler hopes we soon won't need to diet at all.His company,Lifespan Genetics in California,is looking for drugs that have the effects of calorie restriction. Why does the author mention an elderly mouse in paragraph 2?A: To describe the influence of old age on mice.B: To illustrate the effect of meager food on mice.C: To tell us how mice's liver genes behave.D: To inform us of the process of metabolizing drugs.
