    B
    　　Fever has usually been regarded as a threat to health.However,no one has actually proved that fever is dangerous.This fact attracted the attention of Matthew J.Kluger.Imagining that fever might not be as harmful as it had been supposed,Kluger set up a series of experiments with lizards(蜥蜴).
    　　What Kluger and his team did his team did in their first experiment was simple.They put some lizards in a sand-box,one end of which was heated to 44℃,while the other was at a room temperature.It was found that the lizards moved form one part of the box to the other in order to keep a constant temperature of about 38℃.Having shown that normal lizards regulate(调节) their own temperature,Kuger,in a second experiment,then set out to show that lizards,like most other animals,develop fever when infected.This was done by making lizards infected with bacteria (细菌) that were known to cause disease.As the team expected,the infected lizards remained longer in the heated part of the box,until they had raised their body temperatures to two or three degrees above normal.In other words,the sick lizards gave themselves fever.
    　　In a third experiment,the team observed the effect of temperature on the survival of the lizards.One group of infected lizards was given a fever - suppressing(退烧) drug.The other group was given no drug and ran a fever,that is to say,they kept a highter temperature for four or five days before seeking a cooler environment.The results were impressive.Of those which raised their body temperature,all but one remained alive.Of those given the fever - suppressing drug,more than half died.Similar results have since been produced in other animals.For example,infeced fish swim to warmer water,and will die if not allowed to do so.
    　　An important conclusion can be drawn from these experiments.As Kluger points out,lizards have been on earth for hundreds of millions of years.It is reasonable to suppose that a response that is so old has been kept by nature for some purpose.It would appear, therefore, that fever does not make disease worse.Rather it its part of the mechanism(机能) by which infection is controlled.
    　　60.In his experiments,Kluger was hoping to prove that fever ________.
    　　　A.is not harmful to lizards
    　　　B.is not necessarily bad
    　　　C.is necessary for both humans and animals
    　　　D.has the same effect on humans and animals
    　　61.The lizards put in the sand - box in the first experiment _____.
    　　　A.had a fever B.were not sick C.recovered from disease D.died of heat
    　　62.In the third experiment,the lizards given a fever - suppressing drug died because _____.
    　　　A.they had no more fever that they needed
    　　　B.they were normal ones and had no fever
    　　　C.the drug had no iffect on sick lizards
    　　　D.the drug made their body temperature too low
    　　63.How would you understand the underlined words"a response" in the last paragraph?
    　　　A.Gause of disease. B.Recovery from disease.
    　　　C.Relationship between living D.Natural defense in the body against disease.

    My 8-year-old daughter is making an experiment. She has been making her own colorful smile cards and often takes them with her everywhere.
    Last Sunday, I took my kid to go shopping with me. She was hoping to see John, who is an elderly man and gives out samples. We see him from time to time and he is so happy and friendly. John wasn’t at the store on Sunday, so my daughter decided that it would be a good idea to distribute her smile cards to the store’s other employees.
    So she did. In the produce department, she gave a card to a young man and she hoped it would make him smile. And he smiled at her and thanked her. Then she came across an older gentleman who looked rather impatient. And she snuck a card into his cart on top of his groceries, remarking to me later that he looked at her suspiciously as if she was dumping trash in his cart. But I thought he would be happy later.
    When we got back from our shopping trip, she had run out of cards. She was walking by a woman with two babies in her cart. My daughter smiled at her and the young mother smiled back. My daughter came to me and said excitedly, “Mom, I just realized something. You don’t need cards to make someone smile. All you need to do is make eye contact and smile into their eyes and they will smile back.” 
    What a beautiful lesson my daughter reminded me of. You are never too young or too old to experiment with kindness and smiles.
    【小题1】At first, the writer’s daughter made an experiment by ______.

    A．giving smile cardsB．giving samples
    C．making eye contactD．giving groceries
    【小题2】According to the text, John was a man ______.
    A．who is very young and livelyB．who may be a salesman
    C．who is in trouble and needs smilesD．who is never seen to smile
    【小题3】The underlined word “distribute” in paragraph 2 probably means ______.
    A．make upB．tear upC．give outD．sell out
    【小题4】From the text, we can learn that ______.
    A．John got a smile card from the writer’s daughter
    B．the older gentleman would smile later after he got the smile card
    C．we could make others smile only by giving them what they wanted
    D．the mother with two babies smiled because she got a smile card

    American magician David Blaine left the glass box in which he had lived for 44 days without food on October 19, 2003. Hundreds of people came to watch the end of his starvation experiment, which has become one of London’s main tourist attractions.
    Looking thinner and darker, 30-year-old Blaine was taken out of his box over the River Thames and immediately went to hospital. He was then slowly reintroduced to food, a process doctors say could be life threatening. He had been drinking only water since September 5.
    A native of Brooklyn, New York, Blaine first became known as a street magician in the early 1990s. He soon found himself doing magic tricks in bars for the likes of American actor Leonardo DiCaprio and his super model friends.
    Over the last decade Blaine has become famous with a combination of breathtaking magic and clever tricks aimed at getting a lot of attention. In 1999, he was buried in a coffin (棺材) for one week and, in 2000, he spent 62 hours in a giant block of ice. Last year he stood on top of a 25-meter pillar (柱子) in the center of New York for 35 hours before jumping into a pile of boxes.
    “I think a lot of people are unable to accept that they’re able to do what they can do,” he said. “They don’t realize we can survive. The human being is an amazing creation.”
    But he seems to have suffered from spending so long in the glass box. He said that at times he was unable to see, had serious back pains and lost his sense of taste.
    【小题1】It is         for David Blaine to eat food after such a long starvation.

    A．pleasantB．deliciousC．dangerousD．important
    【小题2】Having spent such a long time in the glass box, he suffered the following EXCEPT that         .
    A．he had become blindB．he had serious back pains
    C．he lost his sense of tasteD．he was in weak health
    【小题3】Which of the following can best describe David Blaine?
    A．Serious.B．Adventurous.C．Smart.D．Crazy.
    【小题4】Which of the following is NOT true about David Blaine?
    A．Blaine immediately went to hospital after he was taken out of his box.
    B．Blaine was born and brought up in England.
    C．In Blaine’s opinion, people can create a wonder.
    D．Blaine didn’t have any food for 44 days.

    阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项
    A
    No one is glad to hear that his body has to be cut open by a surgeon（外科医生） and part of it taken out． Today， however， we needn't worry about feeling pain during the operation． The sick person falls into a kind of sleep， and when he awakes， the operation is finished． But these happy conditions are fairly new． It is not many years since a man who had to have operation felt all its pain．

    Soon after 1770， Josept Priestley discovered a gas which is now called “laughing gas”．Laughing gas became known in America．Young men and women went to parties to try it． Most of them spent their time laughing，but one man at a party，Horace Wells，noticed that people didn't seem to feel pain when they were using this gas．He decided to make an experiment on himself．He asked a friend to help him．
    Wells took some of the gas，and his friend pulled out one of Well’s teeth．Wells felt no pain at all．
    As he didn't know enough about laughing gas， he gave a man less gas than he should have． The man cried out with pain when his tooth was being pulled out．
    Wells tried again，but this time he gave too much of the gas，and the man died．Wells never forgot this terrible event．
    56.It is ___________since a man being operated felt all the pain.
    A.a few more years           B.not long       C.few years       D.two thousand years
    57. Long ago, when the sick man was operated on, he___________.
