2. Passage 5 Today anyone will accept money in exchange for goods and services. People use money to buy food， furniture， books， bicycles and hundreds of others they need or want. When they work， they usually get paid in money. Most of the money today is made of metal paper. But people used to use all kinds of things as money. One of the first kinds of money was shells. Shells were not the only things used as money. In China， cloth and knives were used. In the Philippine Islands， rice was used as money. In parts of Africa， cattle were one of the earliest money. Other animals were used as money too. The first metal coins were made in China. They were round and had a square hole in the center. People strung them together and carried them from place to place. Different countries have used different metals and designs for their money. The first coins in England were made of tin. Sweden and Russia used copper to make their money. Later， other countries began to make coins of gold and silver. But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper money looked more like a note from one person to another than paper money used today. Money has had an interesting history from the days of shell money until today. Where were shells used as money in history?

3. Passage 3 Dieting to lose weight has become very popular in recent years. People have become more health conscious and try to take better care of their bodies by eating more nutritiously and exercising more regularly to lose any unnecessary fat that they may have. Not only are people being more careful about what they eat， they are also concerned with how they eat and how their meals are prepared. People are taking more time for each meal. Many avoid the so called ―plastic‖ fast-food hamburgers and choose to eat a salad or a sandwich of more healthful ingredients(成分) in a quiet restaurant with a more leisurely atmosphere. At home， they also try to take enough time to eat a relaxing dinner without phone or TV interruptions. While dieting may be viewed as beneficial， it has also become a serious problem for Americans， particularly for young women. Dieting for them has actually become a psychological addiction( 依 赖 ). They eat so little that they can lose as much as fifty percent of their total body weight， and although they look like skeletons， they still insist that they are fat. The current waves of exercising， dieting and the problems produced have caused many organizations to begin educating the public. Many schools， hospitals， health organizations， newspapers and magazines， for example， are offering classes， printing booklet articles， etc. to inform the public of the way to exercise and diet， of the dangers of dieting too rapidly， and of the places people can go for medical help if they find themselves on the road to ―diet addiction‖.―They look like skeletons‖ in the third paragraph most probably means( ).

2、Translation 2 19(2)Everybody knows that women and men communicate differently. Women are more able to manipulate their facial expressions than men. However， the results are reversed when it comes to expressing anger. Women have a tendency to catch others‘ emotions， although men can hide their expressions better than females. Women are more inclined to face each other and make eye contact when talking. Men are more likely to look away from each other. When in a discussion， men are likely to debate and talk about a range of topics while the ladies may talk at length about one topic. Understanding the difference in communication between men and women might help us communicate with each other in a better way.

5. Passage 20 Clifford Stoll ran a computer system in Berkelely， California. As a system administrator， he kept a close eye on the records. One day， Stoll found something strange in the payment record. There was a 75 cents mistake. One of the thousands of users had used the system for 75 worth of time and not paid for it. It might sound like very little money to worry about. But that 75 cents was the first clue Stoll had to a much bigger problem — that a hacker(黑客)had broken into Stoll‘s computer system. Who was it? Stoll spent the next year trying to find out. During that time the hacker used the system in Berkelely as a starting point to break into military computer systems all over the United States. Stoll had to keep track of the hacker‘s activities on the computer without the hacker‘s knowing someone was watching him. Stoll even made up huge files of false information so the hacker would have lots to read. When the hacker spent long time reading， the telephone company was able to trace the lines. After a year， the hacker was traced back to his computer — in Germany. He was later caught by the German police. Why did Stoll make up huge files of false information?

A. 　He wanted to give the hacker a lesson.

B. 　It would help the telephone company trace the line.

C. 　It would give the police more time to find out the hacker.

D. 　He could watch the hacker‘s activities more closely.
