The ability for some elements to give off radiations is referred as theradioactivity.Part three:Read this article, translate the underlined sentences(15%), answer the questions (15%)and then summarize this article within 100 words (10%).The Dazzle of Lasers(激光)The acronym（首字母缩写词）"laser," describes how the device works: Light Amplification by Stimulated Emission of Radiation. In 1916 Einstein predicted that electrons(电子) in an atom could be deliberately stimulated to emit photons（光子） (light energy) of a certain wavelength. He was right. The laser must first be "pumped" with energy in a variety of ways so that the electrons are excited into higher energy states. But these high energy electrons are unstable--and fall back to a lower energy level. On the way down, their extra energy is released（释放）as light. That light is captured inside the laser and amplified by bouncing it back and forth between mirrors. The laser beam that emerges is amplified, monochromatic （单色的）, coherent light --and it shines with an unearthly power.Not until 1960 did Theodore Maiman, a 33-year-old engineer at Hughes Research Laboratories, build a homely four-inch cylinder containing a ruby rod encircled by a flash tube: the world's first working laser.More than two decades later, the laser has wrought a technological revolution. Lasers are an indispensable tool for delicate eye surgery, and doctors are using lasers experimentally to destroy cancerous tumors(肿瘤), unclog（使畅通） diseased arteries （动脉） and even treat herpes（疱疹）. Just as they provide new tools for health care, however, they also make possible new engines of destruction: recently Dr. Edward Teller, the father of the hydrogen bomb（氢弹）, called on President Reagon to urge that the United States build a space-based laser-weapon system that would use a nuclear bomb to fire brutally intense laser X-rays against enemy missiles in flight.Today pilots flying the new Boeing 767 and 757 aircraft navigate with the aid of new laser gyroscopes（陀螺仪）. Supermarket clerks use lasers to ring up prices at the checkout counter by "reading" universal bar-codes（条形码） printed on packages and canned goods. Powerful lasers cut and weld（焊） steel in factories from Detroit to Tokyo. Artists and filmmakers are beginning to use lasers for animation（动画）: at Lucasfilm, George Lucas has a team of computer wizards（奇才） developing a machinethat uses a computer-driven laser to draw animated images on film; a second film, with human actors, is then merged by laser with the graphics into a single seamless （无缝的） whole.How does the laser work? Anyone who has ever focused sunlight through a magnifying glass and watched paper or dry leaves snap into flames understands the power of concentrated light. Laser light is intense, concentrated light, too, but it works on a different principle. Shine sunlight through a prism（棱镜） and it breaks into the glorious colors of the rainbow. In the scientists' vocabulary, sunlight is "incoherent" --it is made up of a mix of wavelengths spanning the spectrum（光谱）from infrared（红外线） to ultraviolet（紫外线）. Laser light, on the other hand, is monochromatic and coherent－it shines at a single wavelength, and all the light waves march together in step like soldiers on parade（游行）.In the two decades since its invention, the laser has undergone a dramatic transformation: a wide variety of gas, solid-state, diode（二极管） and other lasers has been created. Each shines at a different wavelength; some pulse on and off, others operate continuously.When the laser moved out of the laboratory, one of its first and most significant applications was as a medical tool. Lasers are commonly used for delicate surgery inside the eye. In treating blood-vessel disorders resulting from complications(并发症) of diabetes（糖尿病）, doctors aim a fine beam of argon laser light（氩激光） through the pupil（瞳孔） of the eye and place up to 2000 tiny laser burns very closely around the back portion of the retina（视网膜）. These laser "welds" prevent harmful growth or rupture（断裂） of new, unwanted blood vessels.The very properties that make lasers dangerous --power and heat--are also being put to use to destroy some kinds of brain and spinal（脊髓的） tumors. Lasers have brought a new frontier to neurosurgery（神经外科）. They have made some inoperable tumors operable and high-risk tumors less high risk.Warfare is also changing as laser technology advances. Laser guidance systems have brought once unimaginable accuracy to artillery（炮）. In the near future, higher-intensity lasers may be used to blind the electronic sensory systems of aircraft, missiles, tanks and ships. And ultimately, some visionaries insists, the globe could be surrounded by a platoon（排） of orbiting battle stations armed with lasers capable of destroying planes and missiles within seconds of their beinglaunched.Just as they are opening new doors to medicine and military practices, lasers are also having a profound impact on communications. Instead of sunbeams, today's light-wave communication systems use laser light ricocheting through tiny glass fibers. Lasers generate light waves at extraordinarily high frequencies--in the range of trillions of cycles per second --which makes it possible to transmit enormous quantities of information. In addition, fiber-optic cables are cheaper than copper wire and are not subject to electromagnetic interference, or the annoying cross talk（串话） and static that plague（折磨） current systems. The big breakthrough was the semiconductor laser.Someday laser light may be piped through giant optic cables into deep ocean waters to create undersea farms; it may be beamed into space to talk to orbiting space stations. Lasers also may be used to fire extremely precise light pulses at DNA molecules, altering the structure of chromosomes（染色体） and thereby repairing defective genes --or even creating new forms of life. And eventually billions of lasers will link the world in a vast information network, a global village of light.1.How does the laser work?2.What is the difference between sunlight and the laser?3.Is the laser absolutely safe? If not, please explain.4.What are the advantages of the semiconductor laser in the communications field?5.In what fields is the laser applied?Part one:1.For this purpose, it is necessary to have a good understanding of the fundamentals of thecircuit.2.This coefficient remains to be determined.3.None of the textbook available mentions this point.4.Since feedback plays an important role in the electronic circuit, its study is very important.5.There is an indication that the price of computers will fall further.6.This method does work, but it is not clear in what condition it is that it should be used.7.The output of this factory 10 years ago is 6 times what it is now.8. A new technology introduced in the 1960s, laser can pierce very hard substances.9.For the transistor to work normally, it is necessary to apply a proper voltage across theelectrode.10.The magnetic lines of force representing the magnetic field are some concentric circlessurrounding the wire.11.What is called a robot is a tool which can do work for the human being.12.This type of antenna has the advantages over that one of simple structure and high efficiency.13.Semiconductors are sensitive to light and hear, both of which have a great impact onconductivity.14.Only through a study of the system’s performance is it possible to know its advantages anddisadvantages.15.This book discusses both practical design method and theoretical problems with emphasis onthe basic concept.Part two:1.It is easy to determine the effect of the new drug on the patient.2.The direction of the electric current had been decided before electrons were discovered.3.Sound travels much more slowly that light does.4.This instrument is expensive.5.There are a few exceptions to this rule.6.The hotter the body is, the more energy it radiates.7.This device is small and light.8.That professor is much interested in this topic.9.Our semiconductor industry came into being at the end of the 1950s.10.Both the engineers are busy designing a new type of computer.11.Work equals force multiplied by distance.12.The newly designed instrument is good in quality.13.The ability of some elements ot give off radiations is referred as the radioactivity.Part three:Translation:1. 20多年前，激光引发了一场技术革命。

）V 1.People can be addicted to different things ─e.g., alcohol, drugs, certain foods, or even television. People who have such an addiction are compulsive, i.e., they have a very powerful psychological need that they feel they must satisfy. According to psychologists, many people are compulsive spenders; They feel that they must spend money. This compulsion, like most others, is irrational ─impossible to explain reasonably. For compulsive spenders who buy on credit, charge accounts are even more exciting than money. In other words, compulsive spenders feel that with credit, they can do anything. Their pleasure in spending enormous amounts is actually greater than the pleasure that they get from the things they buy.There is even a special psychology of bargain-hunting. To save money, of course, most people look for sales, low prices, and discounts. Compulsive bargain hunters, however, often buy things that they don’t need just because they are cheap. They want to believe that they are helping their budgets, but they are really playing an exciting game; when they can buy something for less than other people, they feel that they are winning. Most people, experts claim, have two reasons for their behavior: a good reason for the things that they do and the real reason.It is not only scientists, of course, who understand the psychology of spending habits, but also business people. Stores, companies, andadvertisers use psychology to increase business. They co nsider people’s needs for love, power, or influence, their basic values, their beliefs and opinions, and so on in their advertising and sales methods.Psychologists often use a method called ―behavior therapy‖ to help individuals solve their personality problems. In the same way, they can help people who feel that they have problems with money.1). According to the psychologists a compulsive spender is one who spends large amounts of money （）.A. and takes great pleasure from what he or she buysB. in order to satisfy his or her basic needs in lifeC. just to meet his or her strong psychological needD. entirely with an irrational eagerness满分：2 分 C2). According to the writer, compulsive bargain hunters are in constant search of the lowest possible prices （）.A. because they want to save money to help their budgetsB. because they can openly boast of their triumph over others in getting things for lessC. and will not have money problems if they can keep to their budgetsD. but they seldom admit they feel satisfied if they can get things for less than others满分：2 分 A3). Which of the following is TRUE?A. All people spend money for exactly the same reason that they need to buy things.B.Business people and advertisers can use the psychology of money to increase salesC. Business people understand the psychology of compulsive buying better than scientists doD. compulsive bargain hunters do not have problems with money.满分：2 分 B4). The article is mainly about（）.A. the psychology of money – spending habitsB. the purchasing habits of compulsive spendersC. a special psychology of bargain huntingD. the use of the psychology of spending habits in business满分：2 分 A5). From the passage we may safely conclude that compulsive spenders or compulsive bargain hunters（）A. are really unreasonableB. need special treatmentC. are really beyond remediesD. can never get any help to solve their problems with money满分：2 分 B三、阅读理解（共1 道试题，共10 分。

Where is he?Pigeons have been used as messengers for 500 years, because of their special ability to find home. 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 da y, 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 rea l 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 directionB. in a correct directionC. in all directionsD. in a circle5.Pigeons have _____ C ____ to tell the direction when it is cloudy by using the earth,s magnetic field.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 teachersare 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 jobnguage 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 success is simp lifying. In conducting meetings and dealing with industry, reducing a complex problem to the simplest terms is h ighly important.”Is common sense a quality a person is born with, or can you do something to increase it? Th e 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 _____ .anizational 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, c onformist（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 patien ts categorized as manic（疯人）.The “long sleepers” were quite different ind eed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemedto 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 better 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 should ask a question if they can,t think of an answerB.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 manager 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.

Reading Comprehension. 阅读理解（15×2分=15分）Venus(金星)At first, scientists thought that Venus was the planet most likely to have other living creatures. They made some discoveries which made them think this. Venus is the closest in size to the Earth(地球). It seemed to be made in a similar way. It was covered by a layer of "cloud".Later, scientists made more discoveries, which made them think there has never been life on the planet. The layer of cloud is made from sulphuric acid droplets. The surface of the planet is so hot it can melt metal. Any water on the surface would boil away in the heat.Now, once again scientists are beginning to think that there was once life on Venus, and that maybe some still exists. About 50km above the surface of the planet, it is cooler and there is some evidence of water droplets in the clouds, as well as acid. The chemicals in the atmosphere of the planet are different from what scientists had expected. Some scientists say the difference can only be explained by living things changing the atmosphere. Other scientists are less certain. They say it is too soon to understand chemical reactions on another planet.So, is there life on other planets We still don't know.1.Words and its explanations match.
