解析　考查词组，故选B项。

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.

   Mrs Leonard was round and pretty, with shining brown hair and warm, dark,   7   eyes. Everyone adored (敬重) her. But   8   came to love her more than I did. And for a   9   reason.

   The time came for the   10   tests given at our school. I could only just hear out of one ear, and was not   11  to reveal something else that would single   12   out as different. So I cheated.

   As  17   I was the last. But all through the testing I   18   what Mrs Leonard might say to me. I knew from previous years that the teacher   19   things like “The sky is blue.” Or “Do you have new shoes?”

   My   20   came. I turned my bad ear toward her,   21   the other just enough to be able to hear. I waited and then came the words that God had surely put into her mouth,   22   words that changed my life   23   .

EAT YOUR VEGETABLES.　Wash your hands.　Always say "please"　and　"thank you　".We are full of advice for our children,　but when it comes to money,　we often have little to say.　As a result,　our children may grow up with clean hands and good manners,　but without any idea how to　manage their money.Here are some basics that will help guide them their entire lives：
Show them the future.　If your 13-year-old girl were to save $1.000,invest(投资)it at 8% and add $100 every month,　by the time she's 65,she would have $980,983!zxxk
Be careful of credit(信用).Credit cards can help you buy necessary things and build a credit history,　but they must be used responsibly,　which means paying off your debt in time.　Explain to your children that when you buy something using a credit card,　you can easily end up paying two or three times what you would have paid if you used cash.
Teach patience.　Suppose your child wants a new bicycle that costs $150.Rather than paying the cash,　give him some regular pocket money and explain that by putting aside,say,$15 each week,　he will be able to buy it for himself in only ten weeks.
Provide incentive.　Tell your children the importance of saving.　"For every dollar he or she agrees to save and invest rather than spend,　you agree to add another dollar to the pot,　"says Cathy Pareto,　expert in money planning.
Explain your values.　Values and money are deeply intertwined(缠结在一起),　says 　Eilleen 　Gallo,　co-author of The Financially Intelligent Parent.　When your child demands that you buy something,　explain why you really don't want to buy it.　"You might say, 'I'd rather save that money for your education,'"　advises Gallo.　Every time you spend or don't spend money,　you have a chance to share your values.
【小题1】The writer gives some basics to help ____ in a proper way.

James Cleveland Owens was the son of a farmer and the grandson of black slaves. His family moved to Cleveland when he was 9.There, a school teacher asked the youth his name.
"J.C., "he replied.
She thought he had said "Jesse", and he had a new name.
Owens ran his first race at age 13.After high school, he went to Ohio State University. He had to work part time so as to pay for his education. As a second?  year student in the Big Ten games in 1935, he set even more records than he would in the Olympic Games a year later.
A week before the Big Ten meet, Owens accidentally fell down a flight of stairs. His back hurt so much that he could not exercise all week, and he had to be helped in and out of the car that drove him to the meet. He refused to listen to the suggestions that he give up and said he would try, event by event. He did try, and the results are in the record book.
The stage was set for Owens victory at the Olympic Games  in Berlin the next year,  and his success would come to be regarded as not only athletic but also political. Hitler did not congratulate any of the African?American winners.
"It was all right with me, "he said years later."I didn’t go to Berlin to shake hands with him, anyway."
Having returned from Berlin,  he received no telephone calls from the president of his own country,  either. In fact, he was not honored by the United States until 1976, four years before his death.
Owens? Olympic victories  made little difference to him. He earned his living by looking after a school playground, and accepted money to race against cars, trucks,  motorcycles and dogs.
"Sure, it bothered me, "he said later." But at least it was an honest living. I had to eat."
In time,  however,  his gold medals changed his life."They have kept me alive over the years, "he once said. "Time has stood still for me. That golden moment dies hard."
