1. Passage 3 Dieting to lose weight has become very popular in recent years. People have become more health conscious and try to take better care of their bodies by eating more nutritiously and exercising more regularly to lose any unnecessary fat that they may have. Not only are people being more careful about what they eat， they are also concerned with how they eat and how their meals are prepared. People are taking more time for each meal. Many avoid the so called ―plastic‖ fast-food hamburgers and choose to eat a salad or a sandwich of more healthful ingredients(成分) in a quiet restaurant with a more leisurely atmosphere. At home， they also try to take enough time to eat a relaxing dinner without phone or TV interruptions. While dieting may be viewed as beneficial， it has also become a serious problem for Americans， particularly for young women. Dieting for them has actually become a psychological addiction( 依 赖 ). They eat so little that they can lose as much as fifty percent of their total body weight， and although they look like skeletons， they still insist that they are fat. The current waves of exercising， dieting and the problems produced have caused many organizations to begin educating the public. Many schools， hospitals， health organizations， newspapers and magazines， for example， are offering classes， printing booklet articles， etc. to inform the public of the way to exercise and diet， of the dangers of dieting too rapidly， and of the places people can go for medical help if they find themselves on the road to ―diet addiction‖. These days people are dieting more because( ).

A. 　they have become fatter and fatter

B. 　they have realized the danger of eating

C. 　they have become more health conscious

D. 　they have taken better care of themselves

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.

D. 　It proved an idea that remained unclear for over 2000 years.

1. Passage 16 Many a young person tells me he wants to be a writer. I always encourage such people， but I also explain that there‘s a big difference between ―being a writer‖， and writing. In most cases these individuals are dreaming of wealth and fame， not the long hours alone at a typewriter. ―You‘ve got to want to write，‖ I say to them， ―not want to be a writer.‖ The reality is that writing is a lonely， private and poor-paying affair. For every writer kissed by fortune， there are thousands more whose longing is never rewarded. When I left a 20-year career in the U.S. Coast Guard to become a freelance writer， I had no prospects at all. What I did have was a friend who found me a place in a New York apartment building. It didn‘t even matter that it was cold and had no bathroom. I immediately bought a used manual typewriter and felt like a genuine writer. After a year or so， however， I still hadn‘t gotten a break and began to doubt myself. It was so hard to sell a story that barely made enough to eat. But I knew I wanted to write. I had dreamed about it for years. I wasn‘t going to be one of those people who die wondering – what if I would keep putting my dream to the last even though it meant living with uncertainty and fear of failure. This is the Shadowland of hope， and anyone with a dream must learn to live there. The passage is meant to .

A. 　 warn young people of the hardships that a successful writer has to experience

B. 　 advise young people to give up their idea of becoming a professional writer

C. 　 show young people it‘s unrealistic for a writer to pursue wealth and fame

D. 　 encourage young people to pursue a writing career

2. Passage 18 Students can travel in the United States without spending too much money if they follow these suggestions. A travel agent can give you information on special economy fares for trains， buses and planes. Think about hiking or biking for a part of your trip， too. You‘ll not only save money， but you‘ll also see a lot more of the country. Some students may want to travel by car. Be sure to think about going with other students — many colleges have ―ride boards‖ that list when and where other students plan to travel. Many radio stations provide the same sort of service — they announce who‘s driving where， when， how many riders they will take and what the expenses will be. There are many inexpensive， older hotels near bus or train stations. Check your travel guide for names of the best. Many parts of the country also have youth hostels where young people can stay for only a few dollars a night. You don‘t have to eat in restaurants all the time， but we don‘t recommend a diet of candy and cola， either. You can usually get a healthy， cheap breakfast in a restaurant. If the weather is warm， you can buy food in supermarkets or at roadside stands and have a picnic for lunch. For dinner you can get the names of good， cheap restaurants from travel guides or friends. To see more of the country， you‘d better travel( ).

5、Translation 5 With awareness of increasing dishonesty in today‘s society， it‘s sometimes implied that in ―the good old days‖ people were better， happier， and more honest. Were they more honest? Maybe yes， maybe no. Long ago， all American schoolchildren knew the historical story of how Abraham Lincoln walked five miles to return a penny he had overcharged a customer. It‘s the kind of story that we think of as myth. But in the case of Lincoln， the story is true. Every society has stories stressing the absolute value of honesty. It‘s these stories that students need to remember when temptation induces them to cheat.
