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。

Psychiatrists ( 精神病专家) who work with older parents say that maturity can be an asset inchild rearing - older parents are more thoughtful, use less physical discipline and spend more time with their children. But raising kids takes money and energy. Many older parents find themselves balancing their limited financial resources, declining energy and failing health against the growing demands of an active child. Dying and leaving young children is probably the older parents'biggest, and often unspoken, fear. Having late-life children, says an economics professor, often means parents, particularly fathers, "end up retiring much later." For many, retirement becomes an unobtainable dream.Henry Metcalf, a 54-year-old journalist, knows it takes money to raise kids. But he's also worried that his energy will give out first. Sure, he can still ride bikes with his athletic fifth grader, but he's learned that young at heart doesn't mean young. Lately he's been taking afternoon naps (午睡) to keep up his energy. "My body is aging," says Metcalf. "You can't get away from that."Often, older parents hear the ticking of another kind of biological clock. Therapists who work with middle-aged and older parents say fears about aging are nothing to laugh at. "They worry they'll be mistaken for grandparents, or that they'll need help getting up out of those little chairs in nursery school," says Joann Galst, a New York psychologist. But at the core of those little fears there is often a much bigger one: "that they won't be alive long enough to support and protect their child," she says.Many late-life parents, though, say their children came at just the right time. After marrying late and undergoing years of fertility (受孕) treatment, Marilyn Nolen and her husband. Randy,had twins. "We both wanted children," says Marilyn, who was 55 whenshe gave birth. The twins have given the couple what they desired for years, "a sense of family."Kids of older dads are often smarter, happier and more sociable because their fathers are more involved in their lives. 'The dads are older, more mature," says Dr. Silber, "and more ready to focus on parenting."(1).Why do psychiatrists regard maturity as an asset in child rearing?A、Older parents can better balance their resources against children's demands.B、Older parents are usually more experienced in bringing up their children.C、Older parents are often better prepared financially.D、Older parents can take better care of their children.答案： D(2).What does the author mean by saying "For many, retirement becomes an unobtainable dream" (Lines 7-8, Para.1)?A、They have to go on working beyond their retirement age.B、They can't get full pension unless they work some extra years.C、They can't obtain the retirement benefits they have dreamed of.D、They are reluctant to retire when they reach their retirement age.答案： A(3).The author gives the example of Henry Metcalf to show that ____.A、many people are young in spirit despite their advanced ageB、taking afternoon naps is a good way to maintain energyC、older parents tend to be concerned about their aging bodiesD、older parents should exercise more to keep up with their athletic children答案： C(4).What's the biggest fear of older parents according to New York psychologist Joan Galst?A、Being laughed at by other people.B、Slowing down of their pace of life.C、Being mistaken for grandparents.D、Approaching of death.答案： D(5).What do we learn about Marilyn and Randy Nolen?A、They thought they were an example of successful fertility treatment.B、Not until they had the twins did they feel they had formed a family.C、They believed that children born of older parents would be smarter.D、Not until they reached middle age did they think of having children.答案： B2. As evidence that the Earth’s atmosphere is warming continues to accumulate, scientists are making slow progress toward an answer to the big question raised by the evidence: How much of the warming is due to human activity and how much to natural causes?The UN Intergovernmental Panel on Climate Change, the group of scientists widely considered the most authoritative voice on the subject, has already concluded that there is a “discernible human influence” on the global climate. Now the panel is deep into another of its periodic full-scale scientific assessments of global climate change.Some experts on the problem say the human imprint on climate is becoming clearer, and may even have been the dominant factor in the global warming of recent decades. Not everyone agrees and virtually all experts say that in any case, a reliable estimate of the human imprint’s magnitude still remains some distance off.A number of influences, both natural and man-made, cause the planet’s temperature to vary. The natural ones include changes in solar radiation, and sulfate droplets called aerosols cast aloftby erupting volcanoes, which cools the atmosphere by reflecting sunlight.The human influence stems mostly from emissions of waste industrial gases like carbon dioxide, which trap heat in the atmosphere, and sulfate aerosols from industrial smokestacks.Human factors appeared to be playing a part, but no judgment has been made on whether that part was big, small or in between.One recent piece of evidence suggesting a strong human influence, which seems likely to carry some weight with the intergovernmental panel, appeared recently in the journal Nature. Scientists analyzed the global climate record of the last century in an effortto isolate and quantify the major factors producing the century’s rise of about 1 degree Fahrenheit in the Earth’s average surface temperature.The research team found that in the earlier part of the century, the rise could be explained either by an increase in solar radiation or a combination of stronger solar radiation and heat-trapping greenhouse gases emitted by industrial economies. But they found that after the mid-1970s, when about half the century’s warming took place, the warming resulted largely from the greenhouse gases.Meanwhile, evidence of warming and its effects continues to mount. Earlier this year, scientists at the University of Massachusetts and the University of Arizona reconstructed the average annual surface temperature trend of the Northern Hemisphere for the last 1000 years. They found that the 20th century was the warmest of the millennium and that the warmest years of all occurred in the 1990s, with 1998 the warmest on record.(1).The earth’s atmosphere is warming, ______.A、mainly because of human factorB、mainly because of natural causesC、the reason of which is unknownD、which is being studied by scientists答案： D(2).Maybe sulfate aerosols are all caused by ______.A、erupting volcanoesB、industrial smokestacksC、both A and BD、none of the above答案： C(3).In the 20th century the global climate has risen by ______.A、20%B、about 1 degree FahrenheitC、1 degree centigradeD、We have no idea about this.答案： B(4).Which of the following is TRUE according to the passage?A、About half of the 20th century’s rise in average global climate resulted mostly from the greenhouse gases.B、Half of the 20th century’s warming took place in the last thirty years.C、The 20th century is the warmest in the last 1000 years.D、All of the above.答案： D(5).The global climate rise in the earlier part of the 20th century is due to ______.A、an increase in solar radiation onlyB、greenhouse gasesC、eruption of volcanoesD、either an increase in solar radiation or a combination of stronger solar radiation and greenhouse gases答案： D3.Our environment is getting worse and worse with the increase of the world population, which affects the environment in two ways. Firstly, the limited energy resources will be used up much faster. Secondly, the increasing population creates more pollution, another severe problem that needs to be solved. Both problems are long-term ones because actions taken now show their results slowly over many years. They are also urgent because delays in action can lead to great suffering and social problems. The question seems to be difficult to handle for most people. However, a person can be a protector of environment in everyday life if he takes actions to save the environment right now. With the development of technology, cars make transportation easier and quicker than before, but we can’t ignore the disadvantages brought to us by more and more cars in use. For example, we are consuming gasoline（汽油）, which is a non-renewable(无法更新的) resource, and will soon be gone. Moreover, the exhausted gas from cars pollutes our air, and our health is therefore threatened by air pollution, which has a big potential effect on our daily life. So we can consider walking, taking buses, carpooling (合用汽车), instead of driving cars alone. This seems to be a very slow process that can’t be so effective if it’s taken by a single person. But when more and more people become aware of the importance and positively take it as their personal responsibilities, the condition of the air will be improved to a great extent.(1).According to the writer, the main problem to our environment today is_____.A、the increase of populationB、the limited energy resourcesC、the more serious air pollutionD、the development of technology答案： A(2).From the passage, we can know that_____.A、effective measures can be taken mainly by the governmentB、taking measures now can soon improve the environmentC、immediate measures can cause great suffering and social problemsD、every single person’s action has some effect on environment protection答案： D(3).The author’s main purpose in writing this passage is most probably to_______.A、complain about people’s slow actions to protect the environmentB、advise people to take actions to protect the environmentC、show himself to be an active environment protectorD、point out the bad effects of technologies in protecting environment答案： B(4).The author believes that carpooling_____.A、can give help to those without carsB、can save people money and timeC、can save energy resources and reduce air pollutionD、can promote friendship among drivers答案： C(5).The passage is mainly about______.A、environment protectionB、energy crisisC、pollution problemsD、social problems答案： A4. Ironically in theUnited States, a country of immigrants, prejudice and discrimination continue to be serious problems. There was often tension between each established group of immigrants and each succeeding group. As each group became more financially successful, and more powerful, they excluded newcomers from full participation in the society. Prejudice and discrimination are part of American history; however, this prejudicial treatment of different groups is nowhere more unjust than with black Americans.Blacks had distinct disadvantages. For the most part, they came to the “land of opportunity”as slaves and they were not free to keep their heritage and cultural traditions. Unlike most European immigrants, blacks did not have the protection of a support group; sometimes slave owners separated members of the same family. They could not mix easily with the established society either because of their skin color. It was difficult for them to adapt to the American culture. Even after they became free people, they still experienced discrimination in employment, housing and education.Until the twentieth century, the majority of the black population lived in the southern part of theUnited States. Then there was a population shift to the large cities in the North. Prejudice against blacks is often associated with the South. Slavery was more common there and discrimination was usually easier to see.In the 1950s and 1960s, blacks fought to gain fair treatment, and they now have legal protection in housing, education, and employment. Because their neighborhoods are segregated(隔离), many blacks feel that educational opportunities are not adequate for their children. Busing children from one neighborhood to another is one solution to inequality in education. Naturally, all parents want the best possible education for their children.The situation of blacks is better today than it was in the 1950s, but racial tension persists. Time will be the real solution to the problem of race.(1).What is the main subject of the passage?A、Prejudice and discrimination in theUnited States.B、Education in theUnited States.C、Prejudice against American blacks.D、Unemployment in theUnited States.答案： A(2).When a group of immigrants became strong in its economy, they were likely to _____.A、prevent new settlers from being greatly involved in social activitiesB、show prejudice and discrimination against newcomersC、fight with the natives to gain more landD、fight among themselves to establish a more dominating role答案： A(3).According to the passage, which of the following is NOT true?A、Blacks in theUnited Stateswere among those who were worst discriminated.B、Prejudice and discrimination are part of theUnited States.C、It was not easy for blacks to get accustomed to the American culture.D、The problem of prejudice and discrimination in theUnited Stateswon’t be solved before long.答案： A(4).It can be inferred from the passage that_____.A、blacks are free people now， so they can enjoy equal rights as whites.B、the government of theUnited Statesis not attaching great attention to the education of blacks.C、now there are more blacks living in the North than in the SouthD、prejudice and discrimination are more severe in the South than in the North答案： D(5).By “busing children from one neighborhood to another is one solution to inequality in education”, the authorimplies that ____.A、black children are slow in learning in their own neighborhoodB、black children can’t enjoy adequate education if they don’t go farC、black children are severely discriminated in their own neighborhoodD、black children are required to receive an education of a different culture答案： B。
