　　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.

People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a 36 problem. They often accept the opinions or ideas of other people. Other times they begin to act without 37 ; they try to find a solution by trial and error(反复试验). 　38 , when all of these methods 39 , the person with a problem has to start analyzing. There are six 40 in analyzing a problem.

41 ，the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must 42 that there is a problem with the bicycle.

Next, the person must find out the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 43 the parts that are wrong.

Now the person must look for 44 that will make the problem clearer and lead to 45 solutions. For example, suppose Sam decides that his bicycle does not work because there is something wrong with the brakes. 　46 , he can look into his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.

After 47 the problem, the person should have 48 suggestions for a possible solution. Take Sam as an example 49 , his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.

In the end, one 50 seems to be the solution to the problem. Sometimes the

51 idea comes quite 52 because the thinker suddenly sees something new or sees something in a different way. Sam, for example, suddenly sees there is a piece of chewing gum (口香糖) stuck to a brake. He 53 hits on the solution to his problem: he must 54 the brake.

Finally the solution is 55 . Sam does it and finds his bicycle works perfectly. In short he has solved the problem.
