As recently as three decades ago, many Americans believed that using credit was an unwise and dangerous way to pay for what they bought. Some even thought that owing money to a store or a credit company was something to be ashamed of. Good citizens, they believed, always bought what they wanted with real money and they paid the full

price immediately.

Today, however, all that has changed. Credit, as some observers have noted, has become a way of life in the United States. More and more Americans now are depending on those small pieces of plastic, credit cards, to pay for large purchases such as televisions, record players or furniture. Many people today would consider it unusual not to use a credit card to pay for a costly restaurant dinner, a hotel room or an airline trip. And there are some situations in which

Americans must have credit cards. If they want the temporary use of a car, for example, they first must give the car rental company the number of their credit card. That number is considered a guarantee that they will return the car and pay for using it.

Credit cards offer two major services to Americans. First of all, they are easier and safer to carry than large amounts of money. Second, they permit people to borrow, to have the immediate pleasure of owning something, even if they do not have enough money to pay for it at the time. With credit cards people pay for goods or services at the end of each month instead of when they buy them. And when the time does come to pay, most credit cards offer people a

choice. They can pay all of what they owe for the month or they can just pay usually between 5 and 10 percent of what they owe.Why does the car rental company ask for the credit card number?

12.根据以下资料，回答82-85题。 　　Can animals be made to work for us? Some scientists think that one day animals may be trained to do a number of simple jobs that are now done by human beings. 　　They point out that at a circus, for example, we may see elephants, monkeys, dogs and other animals doing quite skillful things．Perhaps you have seen them on the television or in a film．If you watch closely, you may notice that the trainer always gives the animal a piece of candy or a piece of fruit as a reward．The scientists say that many different animals may be trained to do a number of simple jobs if they know they will get a reward for doing them. 　　Of course, as we know, dogs can be used to guard a house, and soldiers in both old and modem times have used geese to give warning by making a lot of noise when a stranger or an enemy comes near．But it may be possible to train animals to work in factories．In Russia, for example, pigeons which are birds with good eyesight, are being used to watch out for faults in small steel balls that are being made in one factory．When the pigeon sees a ball which looks different from others, it touches a steel plate with its beak．This turns on a light to warn people in the factory．At the same time a few seeds are given as a reward．It takes three to five weeks to train a pigeon to do this and one pigeon can inspect 3 000 to 4 000 balls an hour. 　　Apes have been used in America in helping to make cars, and scientists believe that these large monkeys may be one day gather crops and even drive trains.85 Which of the following is not true?

It was sunrise on an August morning when the captainand his crew cast their netssome 50 miles south of Louisiana in the Gulf of Mexico.As the net was pulled over,thecontents poured out followed by excited cries of"Coins!Coins!"The fishermen quickly realized they had realized a fisherman's dream:sunken treasure!And not just any treasure,but early American silver dollars that had gone down 210 years earlier.

In 1784,at the end of the American Revolutionary War,a heavily armed ship wasbound for the port of New Orleans.On board was a fortune in Spanish Silver Dollars.Hundreds of thousands of them were loaded for the trip to New Orleans,yet not a singleone arrived.With no survivors from the ill-fated voyage,historians can only guess at whathappened.Some say powerful storms took her down while others speculate it was treasurehungry pirates(海盗）。Whatever happened,the secret-along with a treasure valued near＄100,000,000 in today's dollars-was sent to a watery gravesome 300 feet below theocean's surface.

Spanish Silver Dollars were the favorite coins of colonial Americans.Widely used andaccepted as payment in the thirteen colonies,the United States government gave them thestatus of official legal tender.Unfortunately,even though they were struck in large quantities,not many of them survive today.After the Civil War,the government withdrew themfrom circulation and they were melted down.Due to the historic discovery of this treasure,GovMint.com is releasing these coins tothe public for an amazingly low price.For a limited time,those authentic silver dollars arepriced at$49 plus shipping and handling-a dramatic reduction from the market price ofthis coin anywhere else worldwide.4.In which section of a magazine would you probably find this article? （）

17.根据以下资料，回答62-65题。 　　If you are like most people, your intelligence varies from season to season．You are probably a lot sharper in the spring than you are at any other time of the year．A noted scientist, Ellsworth Huntington (1876-1947), concluded from other men's work and his own among peoples in different climates that climate and temperature have a definite effect on our mental abilities. 　　He found that cool weather is much more favorable for creative thinking than is summer heat．This does not mean that all people are less intelligent in the summer than they are during the rest of the year．It does mean, however, that the mental abilities of large numbers of people tend to be lowest in the summer. 　　Spring appears to be the best period of the year for thinking．One reason may be that in the spring man's mental abilities are affected by the same factors that bring about great changes in all nature. 　　Fall is the next-best season, then winter．As for summer, it seems to be a good time to take a long vacation from thinking!62 Ellsworth Huntington decided that climate and temperature have __.

18.Whatever you do, don’t challenge a chimpanzee named Ayumu to a number memory game. In 2007, Ayumu became famous for his lightning speed at a game that goes like this: A player views a computer screen where the numbers 1 through 9 appear briefly at once and then turn to white squares.The player then taps the squares where the numbers had been, in order from 1 to 9.People can do it.But no human competitor has ever completed the game faster or more accurately thanAyumu the chimp.For almost five years Ayumu remains undefeated.Psychologist Nicholas Humphrey of Darwin College at Cambridge University in England now thinks he knows the secret behind the chimp’s ability.Humphrey suspects Ayumu’s brain may have a condition that allows the chimp to see numbers as colors.This would mean that Ayumu may see a color glow after the numbers disappears.Then, instead of remembering the numbers, he remembers a sequence of colors, each associated with a number.The condition that Humphrey believes Ayumu may have is called synesthesia.Humans withsynesthesia may associate numbers and letters with colors.For example, a person may see thenumber “5” as the color blue.Until now, scientists had assumed only humans could havesynesthesia.Humphrey found the inspiration for his idea at a 2011 scientific conference.There, he heard apresentation about Ayumu’s memory abilities and another talk about synesthesia.He then put the two ideas together.Not everyone is convinced that Humphrey is correct.Primatologist Tetsuro Matsuzawa of thePrimate Research Institute at Kyoto University in Japan has spent decades studying the amazingmemories of chimpanzees, including Ayumu.He maintains that chimps simply have faster memory recall than people.Which of the following is true of Nicholas Humphrey?
