Otherwise, I ________ part in the seminar onthe WTO.A. would takeB. tookC. would have takenD. had takenDuring the long vacation I was accepted as a bus conductor. I lasted about three weeks. The routes through town were more than the mind could stand even in the off-peak hours. All the buses from our station and every other station would be crawling nose to tail through the town while the entire working population of Sydney fought to get aboard. It was hot that summer: 100° Fahrenheit (华氏) every day. Inside the bus it was 30° hotter still. It was so jammed inside that my feet weren't touching the floor. There was no hope of collecting any fares. At each stop it was all I could do to reach the bell that signaled the driver to close the automatic doors and get going. I had no way of telling whether anybody had managed to get on or off. My one object was to get that bus up Pitt Street.In these circumstances I was scarcely to blame. I didn't even know where we were, but I guessed we were at the top just before Market Street. I pressed the bell, the doors closed, and the bus surged forward. There were shouts and yells from down the back, but I thought they were the angry cries of passengers who had not got on. Too late I realized that they were emanating (来自) from within the bus. The back set of automatic doors had closed around an old lady's neck as she was getting on. Her head was inside the bus. The rest of her, carrying a shopping bag was outside. I knew none of this at the time.When I at last caught on to the fact that something was happening and signaled the driver to stop, he crashed to a halt and opened the automatic doors, whereupon the woman dropped to the road.1.When did the author work as a bus conductor?A.

She got her head caught in the bus doors.D. She signaled the bus driver to stop.Questions 6 to 10 are based on the same passage or dialog. Since the dawn of human ingenuity (独创性), people have devised greater and greater tools to cope with work that is dangerous, boring, burdensome, or just plain nasty. That compulsion (强制) has resulted in attempts to make robots, machines with human capabilities. And if scientists have yet to create the mechanical version of science fiction, they have begun to come close.As a result, the modern world is increasingly full of intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum (忙碌) to the rhythm of robot assembly arms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction. Our subway trains are controlled by tireless robot drivers. And thanks to the continual miniaturization (小型化) of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with perfect accuracy—far greater precision than highly skilled physicians can achieve with their hands alone.But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves-goals that pose a real challenge. "While we know how to tell a robot to handle a specific error," says Dave Lavery, manager of a program at NASA, "we can't yet give a robot enough 'common sense' to reliably interact with a dynamic world."Indeed the quest for true artificial intelligence has produced very mixed results. Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transistor (晶体管) circuits might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries.6.Human ingenuity was initially demonstrated in ________.A. the use of machines to produce science fictionB. the wide use of machines in manufacturing industryC. the invention of tools for difficult and dangerous workD. the clever tackling of dangerous and boring work7.The word "gizmos" (paragraph 2) most probably means________.A. programsB. expertsC. devicesD. creatures8.According to the text, what is beyond man's ability now is todesign a robot that can ________.A. fulfill delicate tasks like performing brain surgeryB. interact with human beings orallyC. have a little common senseD. respond independently to a changing world9.What does the author think?A. Robots will always require supervision.B. People have both successes and failures with robots.C. The making of robots will always meet mixed successes.D. Robots and people should never be mixed.10.What made people optimistic about robots?A. Transistor circuits.B. The 60s and 70s.C. Researchers.D. The human brain.Questions 11 to 15 are based on the same passage or dialog.One phase of the business cycle is the expansion phase. This phase is a two-fold one, including recovery and prosperity. During the recovery period there is ever-growing expansion of existing facilities, and new facilities for production are created. More businesses are created and older ones expanded. Improvements of various kinds are made. There is an ever increasing optimism about the future of economic growth. Much capital is invested in machinery or heavy industry. More labor is employed. More raw materials are required. As one part of the economy develops, other parts are affected. For example, a large expansion in automobiles results in an expansion of the steel, glass, and rubber industries. Roads are required; thus the cement and machinery industries are stimulated. Demand for labor and materials results in greater prosperity for workers and farmers from increased demand for supplies of raw materials. This increases purchasing power and the volume of goods bought and sold. Thus prosperity is diffused (扩散) among the various segments of the population. This prosperity period may continue to rise and rise without an apparent end. However, a time comes when this phase reaches a peak and stops spiraling (盘旋上升) upwards. This is the end of the expansion phase.11.We may assume that in the next paragraph the writer willdiscuss ________.A. the expansion phaseB. the status of the farmerC. the higher cost of livingD. the recession period12.The title below that best expresses the ideas of this passageis ________.A. Attaining Prosperity in One IndustryB. The Recovery StageC. An Expanding SocietyD. A Period of Growth13.Prosperity in one industry ________.A. reflects itself in many other industriesB. will affect the steel industryC. will spiral upwardsD. will end abruptly14.Which of the following industries will probably be a goodindicator of a period of expansion?A. Toys.B. Machine tools.C. Foodstuffs.D. Materials.15.During the period of prosperity, people regard the future________.B. in a confident mannerC. in a careful wayD. indifferently Questions 16 to 20 are based on the same passage or dialog.Are organically grown foods the best food choices? The advantages claimed for such foods over conventionally grown and marketed food products are now being debated. Advocates of organic foods —a term whose meaning varies greatly —frequently proclaim that such products are safer and more nutritious than others.The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the great number of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically-grown foods prevents or cures disease or provides other benefits to health have become widely publicized and popular among customers.Almost daily the public is surrounded by claims for "no-aging" diets, new vitamins, and other wonder foods. There are numerous unsubstantiated (无确实根据的) reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fertilized grains, and the like.One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality thanconventionally grown foods. So there is real cause for concern if consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.16.The word "Advocates" (Para. 1) is closest in meaning to which of the following?A. Supporters.B. Merchants.D. Consumers.17.What does the word "others" (Para. 1) refer to?A. Advantages.B. Advocates.C. Organic foods.D. Nonorganically-grown products.18. The author implies that there is cause for concern if consumers with limited incomes buyorganic foods instead of conventionally grown foods because ________.A. organic foods can be more expensive but are often no better thanconventionally-grown foodsB. many organic foods are actually less nutritious than similar conventionally-grown foodsC. conventionally-grown foods are more readily available than organic foodsD. too many farmers will stop using conventional methods to grow food crops19. According to the last paragraph, consumers who believe that organic foods are betterthan conventionally-grown foods are often ________.A. carelessB. mistakenC. mistakingD. wealthy20.What is the author's attitude toward the claims made by advocates of health foods?A. Very enthusiastic.B. Somewhat favorable.C. Neutral.D. Doubtful.。
