The mystery of the homing pigeon is on how it navigates and how it finds home. We now know that there are two ways that pigeons tell directions. First, they use the sun. Just getting rough directions from the sun is easy. However, getting accurate directions from the sun takes more care. To tell direction accurately from the sun, one needs to know the exact time.All plants and animals seem to have built-in clocks. Usually these biological clocks are not quite exact in measuring time. However, they work pretty well, because they are“reset”every day, maybe when the sun gets up.Do pigeons use their biological clocks to help them find direction from the sun? We can experiment to find out. We can keep pigeons in a room lighted only by lamps. And we can time the lighting to make their artificial“days”start at some different time from the re outside day. After a while we have shifted their clocks. Now we take them far away from home and let them go on a sunny day. Most of them start out as if they know just which way to go, but choose a wrong direction. They have picked a direction that would be correct for the position of the sun and the time of day according to their shifted clocks.The above experiment shows that homing pigeons can tell directions by the sun. What happens when the sky is darkly overcast by clouds and no one can see where the sun is? The pigeons still find their way home. So it seems that pigeons also have some extra sense of direction from the earth’s magnetic field when they cannot see the sun.1. Pigeons have been used as messengers, for they have special ability ______B_______.A. to send lettersB. to find homeC. to carry food for menD. to lead the way for people2. The secret of the homing pigeons is ________B_____.A. how they find foodB. how they find homeC. how they take a letterD. how they take care of children3. All plants and animals reset their biological clocks when ________A______.A. the sun risesB. the sun setsC. the moon risesD. the moon sets4. The experiment tells us that the pigeons fly ____C__ because of the shifted biological clocks.A. in a wrong direction C. in all directionsB. in a correct direction D. in a circle5. Pigeons have ___C___ to tell the direction when it is cloudy by using the earth’s magnetic fiel d.A. sharp eyesB. sensitive hearingC. sense of directionD. brain wavesPassage 2The speaker, a teacher from a community college, addressed a sympathetic audience. Heads nodded in agreement when he said, "High school English teachers are not doing their jobs." He described the inadequacies of his students, all high school graduates who can use language only at a grade 9 level. I was unable to determine from his answers to my questions how this grade 9 level had been established.My topic is not standards nor its decline (降低). What the speaker was really saying is that he is no longer young; he has been teaching for sixteen years, and is able to think and speak like a mature adult.My point is that the frequent complaint of one generation about the one immediately following it is inevitable. It is also human nature to look for the reasons for our dissatisfaction. Before English became a school subject in the late nineteenth century, it was difficult to find the target of the blame for language deficiencies ( 缺陷). But since then, English teachers have been under constant attack.The complainers think they have hit upon an original idea. As their own command of the language improves, they notice that young people do not have this same ability. Unaware that their own ability has developed through the years, they assume the new generation of young people must be hopeless in this respect. To the eyes and ears of sensitive adults the language of the young always seems inadequate.Since this concern about the decline and fall of the English language is not perceived as a generational phenomenon but rather as something new and peculiar to today's young people, it naturally follows that today's English teachers cannot be doing their jobs. Otherwise, young people would not commit offenses against the language.6. The speaker the author mentioned in the passage believed that __ D___.A. the language of the younger generation is usually inferior to that of the older generationB. the students had a poor command of English because they didn't work hard enoughC. he was an excellent language teacher because he had been teaching English for sixteen yearsD. English teachers should be held responsible for the students' poor command of English7. In the author's opinion, the speaker ___B___.A. gave a correct judgment of the English level of the studentsB. had exaggerated the language problems of the studentsC. was right in saying that English teachers were not doing their jobsD. could think and speak intelligently8. The author's attitude towards the speaker's remarks is ___C___.A. neutralB. positiveC. criticalD. compromising9. It can be concluded from the passage that ___D___.A. it is justifiable to include English as a school subjectB. the author disagrees with the speaker over the stadard of English at Grade 9 levelC. English language teaching is by no means an easy jobD. Language improvement needs time and effort10. In the passage the author argues that ___A___.A. it is unfair to blame the English teachers for the language deficiencies of the studentsB. young people would not commit offences against the language if the teachers did their jobs properlyC. to eliminate language deficiencies one must have sensitive eyes and earsD. to improve the standard of English requires the effort of several generationsPassage 3Is there a “success personality”— some winning combination of qualities that leads almost inevitably to achievement? If so, exactly what is that secret success formula, and can anyone cultivate it?At the Gallup Organization we recently focused in depth on success, probing the attitudes and qualities of 1 500 prominent people selected at random from Who’s Who in America. Our research finds out a number of qualities that occur regularly among top achievers. Here is one of the most important, that is, common sense.Common sense is the most prevailing quality possessed by our respondents( 回答者). Seventy-nine percent award themselves a top score in this category. And 61 percent say that common sense was very important in contributing to their success.To most, common sense means the ability to present sound, practical judgments on everyday affairs. To do this, one has to sweep aside extraneous ideas and get right to the core of what matters. A Texas oil and gas businessman puts it this way:“The key ability for su ccess is simplifying. In conducting meetings and dealing with industry, reducing a complex problem to the simplest terms is highly imp ortant.”Is common sense a quality a person is born with, or can you do something to increase it? T oil man’s answer is that common sense can definitely be developed. He attributes his to learning how to debate in school. Another way to increase your store of common sense is to observe it in others, learning from their — and your own — mistakes.Besides common sense, there are many other factors that influence success: knowing your field, self-reliance, intelligence, the ability to get things done, leadership, creativity, relationships with others, and of course, luck. But common sense stands out. If yo u cultivate these qualities, you’ll succeed. And you might even find yourself listed in Who’s Who someday.11. It can be known from the passage that Who’s Who___C___.A. is a very useful book telling us how to succeedB. is a book providing us with the information about the family life of some famous peopleC. is a book providing us with the names and brief biographies of the top successful peopleD. is a book from which we can find out the names of different peoples in the world12. According to the author, common sense____B__.A. is something that common people like bestB. is something that enables one to form correct opinionsC. is a popular quality a person is born withD. is a quality that is possessed by common people13. The word “extraneous”in Paragraph 4 most probably means__D____.A. rightB. extraordinaryC. clearD. not related14. Which of the following is NOT mentioned as a factor for success? BA. Intelligence.B. Modesty.C. Creativity.D. Good luck.15. The passage is mainly concerned with___D___.A. organizational ability and good work habitsB. the way to obtain big profits and achieve fame and successC. knowledge and interest which are primary to successD. what successful people have in commonPassage 4Baekeland and Hartmann report that the“short sleepers”had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.In general, these“short sleeps”appeared ambitious, active, energetic, cheerful, conformist( 不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or workers full-or part-time while going to school. And many of them had a strong urge to appear“normal”or“acceptable”to their friends and associates.When asked to recall their dreams, the“short sleepers”did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.The sleep patterns of the“short sleepers”were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic(疯人).The“long sleepers”were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much bet ter than did the“short sleepers.”Many of the“long sleepers ”were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly states that sleep was an escape from their daily problems.16. According to the report,___ D___.A. many short sleepers need less sleep by natureB. many short sleepers are obliged to reduce their nightly sleep time because they are busy with their workC. long sleepers sleep a longer period of time during the dayD. many long sleepers preserve their sleeping habit formed during their childhood17. Many “short sleepers” are likely to hold the view that __C___.A. sleep is a withdrawal from the realityB. sleep interferes with their sound judgementC. sleep is the least expensive item on their routine programD. sleep is the best way to deal with psychological troubles18. It is stated in the third paragraph that short sleepers __B___.A. are ideally vigorous even under the pressures of lifeB. often neglect the consequences of inadequate sleepC. do not know how to relax properlyD. are more unlikely to run into mental problems19. When sometimes they cannot enjoy adequate sleep, the long sleepers might __A__.A. appear disturbedB. become energeticC. feel dissatisfiedD. be extremely depressed20. Which of the following is Not included in the passage? BA. If one sleeps inadequately, his performance suffers and his memory is weakenedB. The sleep patterns of short sleepers are exactly the sane as those shown by many mental patientsC. Long and short sleepers differ in their attitudes towards sleepD. Short sleepers would be better off with more restPassage 5Not so long ago almost any student who successfully completes a university degree or diploma course could find a good career quite easily. However, those days are gone, even in Hong Kong, and nowadays graduates often face strong competition in the search for jobs.Job seekers first have to make a careful assessment of their own abilities. One area of assessment should be of their academic qualifications, which would include special skills within their subject area. Graduates should also consider their own personal values and attitudes, or the relative importance to themselves of such matters as money, security, leadership and caring for others.The second stage is to study the opportunities available for employment and to think about how the general employment situation is likely to develop in the future. After studying all the various options, they should be in a position to make informed comparisons between various careers.Job application forms and letters should, of course, be filled in carefully and correctly, without grammar or spelling errors.When graduates are asked to attend for interview, they should prepare properly by finding out all they can about the prospective employer. Dressing suitably and arriving for the interview on time are also obviously important. Interviewees should try to give positive and helpful answers and should not be afraid to ask questions about anything they are unsure about. This is much better than pretending to understand a question and giving an unsuitable answer.There will always be good career opportunities for people with ability, skills and determination; the secret to securing a good job to be one of them.21. In Paragraph 1, the sentence“ … those days are gone, even in Hong Kong …”suggest that ___D___.A. Hong Kong is no longer the good place for finding jobsB. nowadays, everyone in Hong Kong has an equal chance of finding a good careerC. it used to be harder to find a good job in Hong Kong than in other countries.D. in the past, finding a good career was easier in Hong Kong than elsewhere22. The word“relative”in Paragraph 2 could best be replaced by“______B____”.A. familyB. comparativeC. considerateD. slight23. The advice given in the first sentence of Paragraph 3 is to ______B_____.A. find out what jobs are available and the opportunities for future promotionB. examine the careers available and how these will be affected in the futureC. look at the information on and probable future location of various careersD. study the opportunities and the kinds of training that will be available24. The word“prospective”in Paragraph 5 is closest in meaning to“___C____”.A. generousB. reasonableC. futureD. ambitious25. In paragraph 5, the writer seems to suggest that _____C___.A. interviewees shou ld ask a question if they can ’t think of an answe rB. pretending to understand a question is better than giving an unsuitable answerC. it is better for interviewees to be honest than to pretend to understandD. it is not a good idea for interviewees to be completely honest in their answersPassage 6Some people believe that international sport creates goodwill between the nations and that if countries play games together they will learn to live together. Others say that the opposite is true: those international contests encourage false national pride and lead to misunderstanding and hatred. There is probably some truth in both arguments, but in recent years the Olympic Games have done little to support the view that sports encourage international brotherhood. Not only was there the tragic incident involving the murder of athletes, but the Games were also ruined by lesser incidents caused principally by minor national contests.One country received its second-place medals with visible indignation after the hockey final. There had been noisy scenes at the end of the hockey match, the losers objecting to final decisions. They were convinced that one of their goals should not have been disallowed and that their opponents’victory was unfair. Their mana ger was in a rage when he said,“This wasn’t hockey. Hockey and the International Ho ckey Federation are finished.”The president of the Federation said later that such behavior could result in the suspension of the team for at le ast two years.The American basketball team announced that they would not yield first place to Russia, after a disputable end to their contest. The game had ended in disturbance. It was thought at first that the United States had won, by a single point, but it was announced that there were three seconds still to play. A Russian player then threw the ball from one end of the court to the other, and another player popped it into basket. It was the first time the USA had ever lost an Olympic basketball match. An appeal jury debated the matter for four and a half hours before announcing that the result would stand. The American players then voted for not to receive the silver medals.Incidents of this kind will continue as long as sport is played competitively rather than for the love of the game. The suggestion that athletes should compete as individuals, or in non-national team, might be too much to hope for. But in the present organization of the Olympics there is far too much that encourages aggressive patriotism.26. According to the author, recent Olympic Games have _____ C_____.A. created good will between the nationsB. bred only false national prideC. barely showed any international friendshipD. led to more and more misunderstanding and hatred27. What did the manager mean by saying“… Hockey and the International Hockey Federation are finished.”BA. His team would no longer take part in the international games.B. Hockey and the Federation are both ruined by the unfair decisions.C. There should be no more hockey matches organized by the Federation.D. The Federation should be dissolved.28. The basketball example implied that ______A_____.A. too much patriotism was displayed in the incident.B. the announcement to prolong the match was wrongC. The appeal jury was too hesitant in making the decisionD. the American team was right in rejecting the silver medals29. The author gives the two examples in Paragraph 2 and 3 to show ____C____.A. how false national pride led to undesirable incidents in international gamesB. that sportsmen have been more obedient than they used to beC. that competitiveness in the games discourages international friendshipD. that unfair decisions are common in Olympic Games30. What conclusion can be drawn from the passage? DA. International contests are liable for misunderstanding between nations.B. Athletes should compete as individuals in the Olympic Games.C. Sport should be played competitively rather than for the love of the game.D. The organization of the Olympic Games must be improved.III. Vocabulary and Structure1.
