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.

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
D. many of them are still in good condition

4. 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 does the author say that even gold and silver were inconvenient if you had to buy something expensive?
A. Because they are difficult for people to obtain.
B. Because they themselves are expensive, too.
C. Because they are not easy to carry around.
D. Because they are easy to steal.
