3. 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. Why did ancient Chinese coins have a square hole in the center?

2. 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. The expression ―keep a close eye on‖ in paragraph 1 most probably means ( ).

4. Passage 13 The favorite food in the United States is hamburger. The favorite place to buy a hamburger is a fast food restaurant. At a fast food restaurant， people order their food， wait a few minutes， and carry it to their tables themselves. People also take their food out of the restaurant and eat it in their cars or in their homes. At some fast food restaurants， people can order their food， pay for it and pick it up without leaving their cars. There are many kinds of fast food restaurants in the United States. The greatest in number sell hamburgers， French fries and so on. They are popular food among Americans. Besides， Italian food， chicken， seafood and ice-cream are very popular， too. The idea of a fast food restaurant is so popular that nearly every kind of food can be found in one. Fast food restaurants are popular because they reflect American life style. Customers can wear any type of dress when they go to a fast food place. Second， they are fast. People who are busy do not want to spend time preparing their own food or waiting while someone prepares it. In fast food restaurants the food is usually ready before the customer even orders it. Finally most food in a fast food restaurant is not expensive. Therefore people are able to buy and eat at a fast food restaurant often， while they may not be able to go to a more expensive restaurant very often. Is the food in fast food restaurants always ready before the customers order it?

A. 　Yes， it is.

B. 　 No， it is seldom ready.

C. 　 Yes， it is cooked to order.

2. Passage 19 Throughout her working life， a ship — like a motorcar — must be serviced regularly if she is to remain efficient. After a period at sea she must be overall checked and any necessary repairs must be made. There are also instances when a ship must be converted from being one kind of carrier to another. Most of today‘s oil， for example， is carried by huge super-tankers. The smaller tankers， many of which are still in good condition， can be converted into bulk carriers(散货船) for the transport of sugar， coal or ore. Conversion or repair work is carried out in a dry dock， a huge hole cut into the ground and lined with concrete. At one end are large gates separating the dock from the river or sea. When these gates are opened， water pours into the dock and fills it. A ship can then enter the dock， where it is carefully fastened in an upright position. When the ship is positioned inside the dock， the gates are closed and the water is pumped out. The vessel slowly settles on to wooden blocks. Wooden supporters are put in position between the ship and the sides of the dock to prevent her from rolling over. Great care is taken to make sure that the ship rests evenly on the keel(龙骨)blocks to prevent damage being done. As soon as the ship is firmly positioned， repair or conversion work can begin on her body or superstructure. Many smaller tankers have been converted into bulk carriers because( ).

A. 　there is a shortage of oil in the world

B. 　large amounts of sugar， coal and ore is needed in the world market

C. 　most of today‘s oil is carried by huge super-tankers

4. Passage 1 The secret of being born lucky is a summer birthday， with May babies most likely to enjoy a lifetime‘s good fortune， according to a study of more than 40，000 people. The time of year at which you are born has an enduring influence on levels of optimism and self-reported luck， according to a research by British and Swedish scientists. May was the luckiest month in which to be born， with 50 percent of those born then considering themselves lucky， while October was the least lucky month， with just 43 percent claiming good fortune. The findings add to growing evidence that the phenomenon of luck is not all down to chance， but is affected by a person‘s general disposition. Other research has shown that whether people think themselves fortunate depends less on objective success than on having a ―glass half-full‖ or ―half-empty‖ approach to life. ―What we are seeing suggests that something is influencing how people perceive their luckiness. My hypothesis is that people create their own luck by traits such as optimism， that luck is a psychological phenomenon rather than a matter of blind chance，‖ said Professor Richard Wiseman， who led the research. The pattern of the result， with those born in spring and in summer reporting themselves luckier than those born in autumn or winter， could have two potential explanations， Professor Wiseman said. Which of the following words can be best replace the word ―trait‖ (Line 7， Para. 2)?

A. 　Quality.

B. 　 Expectation.

C. 　 Belief.

D. 　 Idea
