　　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.

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."

　　The Centers for Disease Control and Prevention says that over 50,000 people every year sustain some sort of winter-related back injury, and 5,800 of those are holiday decorating-related. These aches and pains can __41__ bring trouble to people’s life. It is said that people’s back could sustain all sorts of strain from carrying heavy __42__ , and from the increased stress of lugging suitcases, decorations and gifts. Dr. Alanna Levine spoke to Debbye Turner Bell on “The Early Show” about how to protect the back for the holiday season.

　　The first tip Dr. Levine gave was about carrying heavy shopping bags. Smaller bags, she said, are better. “You don’t want to load everything up into one bag and lug it around,” Dr. Levine explained. “You want to __43__ the weight on your body.” She also recommended putting heavier items towards the bottom in those bags and lighter items on top. Also, if you can, make    __44__ trips to the car to drop off purchases.

　　Travel can be another pain in the back — from carrying heavy luggage. Again, Dr. Levine    __45__ not to pack everything into one bag. Even though it may cost more, she said that packing two smaller bags is safer than packing one heavy one. Also, choose a light-weight bag, so that the only weight you’re carrying is the __46__ inside the suitcase.

　　When __47__ bags from an airport carousel, Dr. Levine suggests standing close to the carousel and bending your knees to lift it up. “You want to avoid that reach-and-lift. It puts a lot of    __48__ on your lower back,” she said.

　　When it comes to holiday decorating, people can get __49__. Dr. Levine suggests decorating in pairs, so one person can hand the lights and ornaments to the other person to hang, as to avoid reaching or twisting to get what you need.
