3. Passage 15 There is a commonly held myth that Einstein was an underachiever at school， but it really isn＇t true. While he may have had difficulties with languages， Einstein excelled in physics， mathematics and music. Einstein held many patents and was a keen inventor. While working at Swiss patent office in Bern he took it upon himself to write his own scientific papers in his spare time， mostly at weekends and in the evenings after work. 1905 was Einstein＇s miracle year. During this year he wrote three fundamental papers， any of which would have guaranteed him immortality in the world of physics. His first was on a new understanding of the structure of light. Einstein argued that light is composed of small particles of energy， called photons， as well as oscillating waves. The second paper built upon the theory of kinetics. Einstein explained how atoms were responsible for the buffeting of particles of material in suspension， like cigarette smoke suspended in air. This paper presented the first direct evidence for the existence of atoms， vindicating an idea that had been around for over 2000 years. His third paper of 1905 was ―On the Electrodynamics of Moving Bodies‖. Here Einstein derived the theory of ―special relativity‖. In a supplementary paper four months later， he formulated the famous equation， E=mc2， where mass and energy are equivalent， showing that a very small amount of mass converts to a huge amount of energy. This is the driving force behind atomic bombs， and all the stars in the Universe. What effect did Einstein‘s second paper have?

A. 　It explained how light was composed of.

B. 　It explained how cigarette smoke suspended in air.

C. 　It provided direct evidence to oppose the existence of atoms.

4. Passage 2 Man has always wanted to fly. Some of the greatest men in history had thought about the problem. One of them， for example， was the great Italian artist， Leonardo Da Vinci. In the 16th century he made designs for machines that would fly， but they were never built. Throughout history， other less famous men had wanted to fly. An example was a man in England 800 years ago. He made a pair of wings from chicken feathers. Then he fixed them to his body and jumped into air from a tall building. He did not fly very far. Instead， he fell to the ground and broke every bone of his body and rested in peace. The first real step took place in France， in 1783. Two brothers， the Montgolfiers， made a very large ―hot air balloon‖. They knew that hot air rises. Why not fill a balloon with it? The balloon was made of cloth and paper. In September of that year， the King and Queen of France came to see the balloon. They watched it carry the very first air passengers into the sky. The passengers were a sheep and a chicken. We do not know how they felt about the trip. But we do know that the trip lasted eight minutes and that the animals landed safely. Two months later， two men did the same thing. They rose above Paris in a balloon of the same kind. Their trip lasted twenty-five minutes and they traveled about. The very first air passengers in the balloon were.

A. 　two animals

B. 　 the Montgolfiers

C. 　 two Frenchmen

D. 　 the King and Queen

3. Passage 11 Many children use the Internet to get useful knowledge and information， and to relax in their free time. But some of them are not using in a good way. Here are some rules to make sure you are safe and have fun on the Internet. Make rules for Internet use with your parents. For example， when you can go online， for how long and what activities you can go online. Don‘t give your password to anyone else， and never leak out the following information---your real name， home address， age， school， phone number or other personal information. Check with your parents before giving out a credit card number. Never send a photo of yourself to someone in e-mail unless your parents say it‘s OK. Check with your parents before going into a chat room. Different chat rooms have different rules and attract different kinds of people. You and your parents must make sure it‘s a right place for you. Never agree to meet someone you met on the Internet without your parent‘s permission. Never meet anyone you met on line alone. Always remember that people online may not be who they say they are. Treat everyone online as strangers. If something you see or read online makes you uncomfortable， leave the site. Tell a parent or teacher right away. Treat other people as you‗d like to be treated. Never use bad language. Remember—not everything you read on the Internet is true. The underlined phrase ―leak out‖ in the third paragraph may mean ―( ).

A. 　give away

B. 　 leave out

C. 　 give out

2. 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. Research shows that people‘s physical and mental health( ).

A. 　depends on their ability to deal with daily worries and troubles

B. 　relies on the social welfare systems which support them

C. 　has much to do with the amount of support they get from others

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( ).

A. 　every cent was important to the company

B. 　it might lead to a greater loss for the company

C. 　he was afraid the computer system might break down some day

D. 　he realized someone had broken into the computer system
