Many people believe that they deserve success simply because they believe that they deserve success.But there is a widespread belief that people who get on in life may be successful not because they deserve it, but because of influential (有影响的)& friends or the right background. Sometimes it may just be a comforting and harmless belief, while at the other extreme it can be very destructive. I once met a brilliant young engineer who worked in a chemical plant. Because of her knowledge and experience, she should have been promoted to Production Manager. Instead, the job went to a man who was totally unsuited for the post. Everyone knew that he only got it because he was politically acceptable to his superiors (上司). This injustice discouraged the young engineer and many of her colleagues. It also meant that the factory was much less efficient than it could have been.At the same, we should not be pessimistic (悲观的). More and more then modern world depends on having people who are in the job because they are good enough, not just because their faces fit. There is a story of a factory owner who sent for an engineer to see to a machine which would not go. He examined it, then took out a hammer and tapped, once. The machine started up immediately. When he presented his bill, the owner protested, “This can't be right! $ 100 just for tapping a machine with a hammer?” The engineer wrote out a new bill: “For tapping a machine, $1; for knowing where to tap. $99.”56. The engineer at the chemical plant was not promoted because _____.A. it was politically less good for the boss to accept her than the manB. her boss did not think she had the fight qualifications for the jobC. the man who got the promotion was more experienced than she wasD. it is more difficult for a woman to get a promotion than for her male colleague57. The engineer who repaired the machine was right in charging $ 100 because____.A. he hit the machine to get it started againB. the factory owner could not have repaired it himselfC. he was charging for his knowledge and expert skillsD. he was the only person who could find out what was wrong with it58. What can we learn about the author's attitude toward the widespread belief that “people get on in life may be successful not because they deserve it”?A. He quite agrees with it.&&&&&&&& B. He doesn't express his opinion his opinion at it.C. He completely disagrees with it.&&&&&&&&& D. He doesn't quite agree with it.59. According to the text, which of the following is NOT true?A. Having influential friends or right background seems helpful sometimes.B. The engineer had good reason to overcharge the factory owner.C. Not all those who are good in their jobs have the chance to be promoted.D. Those who are good in their jobs are still largely needed by the modern society.BArt Lecture:Artist Zhang Xiaogang from Tsinghua Academy of Fine Arts will give a lecture on Chinese contemporary culture and art on Saturday afternoon.A painter himself, Zhang will mainly talk about the past twenty years.Tickets: 50 Yuan (US$6)Time/ Date: 8:00 to 10:00 pm, March 8 (Sat.)Lee’s Antique Carpet, in the Kent Centre,Liangmaqiao Lu, Chaoyang DistrictTel: Make-up FunLearn to paint Peking Opera masks (脸谱) with artists on Sunday.The artists will explain the basic meaning of each type.

If you're a fan of Rolling Stones and want to go to their concert, which telephone number will you call?& A. &&&&&&&& B. &&&&&&& C. &&&&&& D. CLike business and industry, the academic world is changing with technology Advancing. A library is one place where we can see changes. Many innovative(革新的) things are happening in both public and university libraries. Libraries using new equipment and techniques for research, and librarians are teaching students the new techniques.One service that some university libraries are now providing is a computer search of materials for students doing research. Before starting a research project, students may check with their library to see if a computer search is worthwhile. This kind of search cannot help with all research projects, but it can save time if the topic is in the computer's database(数据库). When you are doing a manual (人工的) search for a research paper, you look at all the indexes(索引) suitable for the research topic. You look up the words related to the topic in the indexes. It takes many hours to look up this information and write down the references. A computer search is faster and easier. You and a librarian decide on the words to enter the computer. The computer looks for these words in this database and gives you a list of reference for your topic. A computer can take two or more ideas and produce references that combine those ideas. A computer search can also be more complete than a manual search.College and university libraries are providing other technological services as well. Another change is the frequent use of microfilm. Libraries are able to collect building by having newspapers, magazines, and other documents on microfilm. Students use microfilm readers in the library for these materials.These innovations in libraries are helpful to library users, but they are also expensive. Many libraries are facing budget problems. There is more techno as a result, libraries are facing budget problem. There is more techno as a result, libraries are paying higher costs for the equipment that makes researches easier.64. Before a research begins, students may find out in the library_____.A. if librarians are helpful to them&&&&&&& B. if a computer search will be usefulC. if a computer writes out a list of the words they enteredD. if the computer looks through its database to choose their topic65. When the computer's database includes the research topic_____.A. computer searches can save timeB. computer searches are useless for most kinds of researchC. computer searches are not helpful before the research projectD. a computer search for materials is the best way to begin any type of research66. Libraries can keep larger amounts of materials by _____.A. buying a lot of newspapersB. using different indexes from other university librariesC. collecting more information on other university buildingD. having microfilm copies of newspapers and other documents67. What can be concluded from the last paragraph?A. Technological innovations are helpful but expensive.B. Libraries have budget problems because it is easier to use newspapers.C. Libraries have budget problems because of the many library users.D. Technological equipment makes research easier for the library &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& DMany people like the feeling of the gentle wind in spring. Many like to see the falling leaves dancing in the wind in autumn. But sometimes, when the wind becomes a storm, it can be very destructive (毁灭性的).A series of such storms struck the US last month and caused very serious damage and human pain.Every year, major storms cause many problems around the world. There is nothing people can do to stop these powerful forces of nature. But new techniques are helping scientists to predict(预测) how, when, and where big storms will happen. The more exact scientists’ warnings are, the better people can prepare for the storms.Predictions are improving. “We’ve gotten better over the years, especially the last few years,” says Phil Klotzback, a scientist at an American university. How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the storm to a new direction. “For a hurricane to happen, conditions have to be just right,” Klotzback says.&&& First, the ocean water needs to be warm enough so that it evaporates and rises into the air. As it rises, the vapor(水蒸气) cools and turns back into liquid. This process gives off heat. This produces energy like an engine that causes winds to increase. It drives the formation of a hurricane.If wind speeds reach 40 miles per hour, the system is called a “ tropical storm”, and it gets a name. At 75 miles per hour, it becomes a hurricane.Hurricanes that hit the US start when a thunderstorm forms off the coast Africa. Storms also develop over tropical waters in other parts of the world.On average, 60 or 70 storms form off Africa every year. About 10 of them get names. There are usually about six hurricanes.

For example, whole grains, dried beans, and corn oil are health foods. A narrower classification of health food is natural food. This is used to distinguish between types of the same food. Raw honey is a natural sweetener,(甜味佐料) whereas refined sugar is not. Fresh fruit is a natural food, but canned food, with sugars and other additives(添加剂)， is not. The most precise term of all and the narrowest classification within health foods is organic food, used to describe food that has been grown on particular kind of farm. Fruits and vegetables that are grown in gardens that are treated only with organic fertilizers, that are not sprayed with poisonous insecticides(杀虫剂), and that are not refined after harvest, are organic foods. Meats, fish, dairy and poultry products from animals that are fed only organically-grown feed and that are not injected with hormones（激素） are organic foods.&&&&& In choosing the type of food you eat, then, you have basically two choices: inorganic, processed foods, or organic, unprocessed foods. A wise decision should include investigation of the reason why processed foods contain chemicals, some of which are proved to be toxic and why vitamin content is greatly reduced in processed foods.&&&&& Bread is typically used by health food advocates as an example of a processed food. First, the seeds form which the grain is grown are treated with a chemical which is extremely toxic. Later the grain is sprayed with a number of very toxic insecticides. After the food has been made into flour, it is made white with another chemical which is also toxic. Next, a dough conditioner is added along with a softener. The conditioner and softener are poisonous, and in fact, the softener has sickened and killed experimental animals.&&&&& A very toxic anti-fungal (抗真菌的)compound is added to keep the bread from getting moldy.&&&&& Other foods from the supermarket would show a similar pattern of processing and preserving. You see, we buy our food on the basis of smell, color, and texture, instead of vitamin content, and manufacturers give us what we want-even if is poisonous. The alternative? Eat health foods!72.
