Banks are not ordinarily prepared to pay out all accounts(账，账户); they rely on depositors (储户) not to demand payment all at the same time. If depositors should come to fear that a bank is not safe, that it cannot pay off all its depositors, then that fear might cause all the depositors to appear on the same day. If they did, the bank could not pay all accounts. However, if they did not all appear at once, then there would always be enough money to pay those who wanted their money when they wanted it. Mrs. Elsie Vaught has told us of a terrifying bank run that she experienced. One day in December of 1925 several banks failed to open in a city where Mrs. Vaught lived. The other banks expected a run the next day, and so the officers of the bank in which Mrs Vaught worked as a teller had enough money on hand to pay off their depositors. The officers simply told the tellers to pay on demand. The next morning a crowd gathered in the bank and on the sidewalk outside. The length of the line made many think that the bank could not possibly pay off everyone. People began to push and then to fight for places near the tellers’ windows. The power of the panic atmosphere was such that two tellers, though they knew that the bank was quite all right and could pay all depositors, drew their own money from the bank. Mrs Vaught says that she had difficulty keeping herself from doing the same.

　　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.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有一项为多余选项。
A.　Goods for auction (拍卖) sales
　　B.　Definition of bidding
　　C.　Way to sell more goods by auction
　　D.　Auction sales in history
　　E.　Brief introduction to auctions
　　F.　Making a larger profit as an auctioneer
【小题1】______
Auctions are public sales of goods, conducted by an officially approved auctioneer. He asks the crowd assembled in the auction-room to make offers, or “bids”, for the various items on sale. He encourages buyers to bid higher figures, and finally names the highest bidder as the buyer of the goods. This is called “knocking down” the goods, for the bidding ends when the auctioneer strikes a small hammer on a table at which he stands.
【小题2】 ______
The ancient Roman probably invented sales by auction, and the English word comes from the Latin auction, meaning “increasing”. The Romans usually sold in this way the goods taken in war. In England in the eighteenth centuries, goods were often sold “by the candle”: a short candle was lit by the auctioneer, and bids could be made while it stayed alight.
【小题3】 ______
Practically all goods whose qualities vary are sold by auction. Among these are coffee, skins, wool, tea, furs, silk and wines. Auction sales are also usual for land and property, furniture, pictures, rare books, old china and similar works of art.
【小题4】 ______
An auction is usually advertised beforehand with full particulars of the articles to be sold and where and when they can be viewed by potential buyers. If the advertisement cannot give full details, catalogues are printed, and each group of goods to be sold together, called a “lot”, is usually given a number. The auctioneer need not begin with Lot 1 and continue in the order of numbers: he may wait until he notices the fact that certain buyers are in the room and then produce the lots they are likely to be interested in.
【小题5】 ______
The auctioneer’s services are paid for in the form of a percentage of the price the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding as high as possible. He will not waste time by starting the bidding too low. He will also play on the opponents among his buyers and succeed in getting a high price by encouraging two business competitors to bid against each other.

Remind children that bad things don’t last. It may sound simple, but the message is extremely important. “Children often don’t have the experience to know that when something bad happens—they lose an important game or their best friends lets them down—it’s not the end of the world,” explains Nancy Leffert, a senior research scientist with the Research Institute, an American adolescents’(青少年) and children’s research group. “They think their bad feelings will last for ever， or that one failure will ruin everything.”
Unfortunately, that kind of thinking discourages motivation(动机).“If a child believes that the cause of her upset is lasting, or that nothing she does will make a difference, it decreases her ability to keep on trying,” says Dorothy Rich, president of the Mega Skills Education Center of the Home and School Institute, based in Washington. Any time you can help your child see that a situation is not lasting, that a result can be changed, or that one opinion does not reflect reality, you give her reason to hope.
Case in point: “When my daughter Kathy was eight，art was one of her favorite subjects，”says Beth，a mother of two. “Then she got an art teacher who gave a great deal of praise to one student and barely noticed the rest．Kathy was ready to give up until I explained to her，‘Never stop doing your best just because one person doesn’t give you praise.’” Beth had to repeat the advice often，and finally her daughter got the message．“Kathy is twelve now, and art is still one of her strongest subjects.”

A. “If you call your friend and apologize，he won’t stay mad at you.”
B.　“That may be what your teacher thinks, but I see it differently.”
C.　“You have lost today, but you can try again tomorrow.”
D.　“Go ahead. Don’t care what other people think.”
