3. 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. Stoll was concerned about a 75 cents mistake because( ).

5. 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. What is the best title for the passage?

A. 　Luck is Something Born

B. 　Luck is Not All Down to Chance

C. 　Luck is a Matter of Blind Chance

D. 　Luck and Age

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.

1. Passage 17 Since we are social beings， the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human conditions is our tendency to give and receive support from one another under stressful circumstances. Social support consists of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to cope with life changes and daily hassles. People with strong social ties live longer and have better health than those without such ties. Studies over a range of illnesses， from depression to heart disease， reveal that the presence of social support helps people fend off illness， and the absence of such support makes poor health likely. Social support cushions stress in a number of ways. First， friends， relatives， and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted by others despite our faults and difficulties. Second， other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third， we typically find social companionship supportive. Engaging in leisure-time activities with others helps us to meet our social needs while at the same time distracting us from our worries and troubles. Finally， other people may give us instrumental support ― financial aid， material resources and needed services — that reduces stress by helping us resolve and cope with our problems. Interpersonal relationships are important because( ).

A. 　they can cure a range of illnesses such as heart disease， etc.

B. 　they help people to cope with life in the information era

C. 　they awaken people‘s desire to exchange resources

D. 　they are indispensable to people‘s social well-being

3. Passage 6 Community service is an important component of education here at our university. We encourage all students to volunteer for at least one community activity before they graduate. A new community program called ―One On One‖ helps elementary students who‘ve fallen behind. Your education majors might be especially interested in it because it offers the opportunity to do some teaching， that is， tutoring in Math and English. You‘d have to volunteer two hours a week for one semester. You can choose help a child with Math， English， or both. Half-hour lesson are fine， so you could do a half hour of each subject two days a week. Professor Dodge will act as a mentor to the tutors ---- he‘ll be available to help you with lesson plans or to offer suggestions for activities. He has office hours every Tuesday and Thursday afternoon. You can sign up for the program with him and begin the tutoring next week. I‘m sure you will enjoy this community service and you‘ll gain valuable experience at the same time. It looks good on your resume， too， showing that you‘ve had experience with children and that you care about your community. If you‘d like to sign up， or if you have any questions， stop by Professor Dodge‘s office this week. What does Professor Dodge do?
