5. Passage 4 Do you know who Benjamin Banneker was and what he did? Benjamin Banneker was a self-educated scientist at a time when most African Americans were slaves. Born a free black man in the British Colony of Maryland in 1731， he received some formal education， but he mostly borrowed books and taught himself science and mathematics. At 22， he borrowed a pocket watch， and without any training， figured out how to carve a working wooden clock that chimed each hour. Because of this clock， he became well known and people would visit him just to see his creation. Banneker ran his family farm from many years， but when he was in his late 50s， a neighbor‘s son lent him a telescope. He became interested in astronomy， the study of the planets and stars， and again taught himself a new science. He made calculations of tides， sunrises and sunsets， and even predicted an eclipse. For several years he published an almanac of these calculations. Today， he is best known for publishing six almanacs， called ―Benjamin Banneker‘s Almanac‖ between 1792 and 1797. In the 1790s， Banneker also helped survey and lay out the land for Washington， D. C.， which became the nation‘s capital. For a look at Banneker‘s amazing life， visit the Benjamin Banneker Historical Park & Museum in Ellicott City， Maryland. Which of Mr. Banneker‘s works is best known?

A. 　Eclipse prediction.

B. 　Helping surveying the capital.

C. 　Benjamin Banneker‘s Almanac.

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 ( ).

A. 　to watch carefully

B. 　 to notice unexpectedly

C. 　 to study closely

D. 　 to observe at a short distance

4. 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. What do you think will happen to a dry dock when the repairs to a ship are completed?

A. 　The water is pumped into it again.

B. 　The gates are opened and the water pours in.

C. 　It is floated out to sea.

D. 　It is converted to another kind of dock.

8、Translation 8 Air pollution can spread from city to city. It even spreads from one country to another. So air pollution is really a global problem. Air pollution may kill people， especially babies， older people， and those who have diseases with their breath. Air pollution increases the risks of certain lung diseases. There are other possible health dangers from air pollution that we don‘t know much about. For example， scientists are trying to find out whether chemicals that reach us from the air may cause changes in our cells. These changes might cause babies to be born with serious birth defects. Scientists are trying to learn how all the chemicals we are apt to take into our body work.
