3. 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. He became famous at the age of 22 because of.

2. Passage 9 What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage. Escaping a fire is a serious matter. Knowing what to do during a fire can save your life. It is important to know the ways you can use and show them to everyone in the family， such as stairways and fire escapes， but not lifts. From the lower floors of the buildings， escaping through windows is possible， learn the best way of leaving by windows with the last chance of serious injury. The second floor window is usually not very high from the ground. An average person， hanging by the finger-tips will have a drop of about six feet to the ground. It is about the height of an average man. Of course， it is safer to jump a short way than to stay in a burning building. Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may leak into the room. On a second or third floor， the best windows for escape are those that open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and grass can help to break a fall. It is possible to escape through the windows( ).

A. 　if there are some bushes on the ground

B. 　if you are strong enough

C. 　if you live on a lower floor

D. 　if you have a long rope

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

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.
