This is what many scientists are doing as they work on the Human Genome Project. The aim of the project is to decode (破译) all of the some 100,000 genes in the human body. Scientists are using DNA fingerprinting techniques to do the decoding.2.DNA.is the substance found in the chromosomes (染色体) of a cell. A chromosome is a chain of genes. Each gene carries a piece of genetic information. At any one moment in a cell, thousands of genes are turned on and off to produce proteins (蛋白质). The challenge for scientists is to find out what role each gene plays in protein production. At some point this decoding will be complete. Then scientists will have a map of an ideal genome, or a picture of the total genetic nature of a human being. The ideal genome is called a consensus (交感) genome. Everything works well in a consensus genome.3.But no one in the world has a consensus genome. Everyone's genome is different from the ideal. These differences are referred to as genetic mutations (突变). Genetic mutations in a person's genome mean that the person has a greater than average chance of suffering from health problems. Some problems are not life-threatening. These would include things like colorblindness, or mild headaches. Other problems are serious, such as heart disease, or cancer.4.It will take years to identify the role of each of the 100,000 genes. The short-term goal of the project is to find the physical and mental health problems a person is likely to encounter during his or her lifetime. The long-term goal is to have each person live a longer, healthier life.(分数:24.96)(1).A.How does DNA work?B.What is the Human Genome Project about?C.How are the DNA samples collected?D.What are the goals of the Human Genome Project?E.What is the role of each gene?F.What are the consequences of genetic mutations?Paragraph 1 ______(分数:3.12)填空项1:__________________ (正确答案:B)解析:(2).Paragraph 2 ______(分数:3.12)填空项1:__________________ (正确答案:E)解析:(3).Paragraph 3 ______(分数:3.12)填空项1:__________________ (正确答案:F)解析:(4).Paragraph 4 ______(分数:3.12)填空项1:__________________ (正确答案:D)解析:(5).A.that person's healthB.a scientific answerC.scientific researchersD.the genesE.the functionF.the sizeThe Human Genome Project is trying to map all ______ that make us human.(分数:3.12)填空项1:__________________ (正确答案:D)解析:(6).Decoding the human genome is a challenge to ______.(分数:3.12)填空项1:__________________ (正确答案:C)解析:(7).Genetic mutations in a person's genome may affect ______.(分数:3.12)填空项1:__________________ (正确答案:A)解析:(8).Scientists are trying hard to discover ______ of each of the genes in our body.(分数:3.12)填空项1:__________________ (正确答案:E)解析:Early Ideas about the Universe1.Early man got his ideas about the universe by looking at the stars as you do. He observed carefully, and learned many things about the sun, the moon, and the stars.2.Suppose you were asked to collect evidence about the sun as early man did. You might go out morning after morning and see it come up in the east. Even on cloudy mornings, you would observe that the darkness goes away and the world becomes light. You might not see the sun but would be sure it is there, because you notice that the earth warms up. As you continued, the sun climbs higher in the sky each day during part of the year. It stays in the sky longer. The earth gets warmer. Things begin to grow. It is spring and then summer.3.After a while the sun stays in the sky for shorter and shorter periods. Many plants begin to die. Leaves fall. Winter comes. Year after year this is repeated and you cannot tell exactly why it happens. But you realize that the sun seems to make the difference. Primitive (原始的) man felt that since the sun was so powerful it must be a god. It may seem silly to us now to worship (崇拜) a sun-god, but primitive man was right about the importance of the sun to life on earth. 4.You have been told that the world is round. But suppose no one had ever taught you that the world was like a huge ball. Would you have ever thought of it yourself? You cannot see the curve (曲线) of the earth at once. You would have no idea of how big it was. That's why early man believed that the earth was small and flat. Such ideas appeared from the evidence they had.5.If you watch the stars night after night, you will see them rise and set. As you look at the sky, it is not difficult to imagine that you are in the center of a vast collection of twinkling (闪烁) lights. Some early astronomers (天文学家) believed the sky was a crystal shell or series of crystal shells, one inside the other. They believed this because that is what the night sky looked like. For many centuries, men believed that the earth was the center of the universe and that the sun, the moon, and the stars circled around it.(分数:24.96)(1).A.Early Ideas about the Sky and the StarsB.The Importance of the Sun to Life on EarthC.Primitive Knowledge of the MoonD.The Sun in Autumn and WinterE.Early Ideas about the EarthF.Collecting Evidence about the SunParagraph 2 ______(分数:3.12)填空项1:__________________ (正确答案:F)解析:(2).Paragraph 3 ______(分数:3.12)填空项1:__________________ (正确答案:B)解析:(3).Paragraph 4 ______(分数:3.12)填空项1:__________________ (正确答案:E)解析:(4).Paragraph 5 ______(分数:3.12)填空项1:__________________ (正确答案:A)解析:(5).A.he did not observe the sun carefully enoughB.he could not see its curveC.the sun, the moon and the stars seemed to move around itD.the earth circles around the sunE.it looked like that at nightF.it has power over life on earthEarly man thought the earth was small and flat because ______.(分数:3.12)填空项1:__________________ (正确答案:B)解析:(6).Primitive man believed the sun was a god because ______.(分数:3.12)填空项1:__________________ (正确答案:F)解析:(7).Early man thought the earth was the center of the universe because ______.(分数:3.12)填空项1:__________________ (正确答案:C)解析:(8).Early astronomers believed that the sky was a crystal shell or series of crystal shells because ______.(分数:3.12)填空项1:__________________ (正确答案:E)解析:A.Star Is Born1.The VLT (Very Large Telescope) is the world's largest telescope (望远镜) and is taking astronomers (天文学家) further back to the Big Bang than they ever thought possible. Located 2,600 metres up in the Chilean Andes, it has four huge mirrors, each about the size of a London bus. The VLT is so powerful it can spot a burning match 10,000 kilometres away.2.This astonishing power will allow astronomers to see events in space from the birth of stars to the collision (碰撞) of galaxies (星系) on the edge of the cosmos (宇宙). The VLT is giving astronomers their best-ever view of the cosmos. The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed.3.Take the case of Eta Carinae, one of the most explosive stars in the universe. This star produces ultraviolet laser rays (紫外线) and it will destroy itself in a few million years' time. It is five times brighter than the sun and when it explodes it is going to be a sight worth waiting for!4.But it is at distances of millions, even billions, of light years that the VLT really shows its power. The VLT can detect light that set out on its journey before the earth even existed. This gives astronomers their first-ever detailed views of events that took place in the earliestdays of the cosmos.5.In other words, the VLT is a kind of a time machine. It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisions can now be seen by scientists, and astronomers believe the telescope will reveal more about these exciting events in the years to come. One day, we might be able to say we have traveled back to the beginning of time, and we will have a much clearer picture of how our planet was born.(分数:24.96)(1).A.Events that took place before the earth existedB.Power of the telescopeC.Details of Eta CarinaeD.Invention of a time machineE.Biggest telescopeF.Birth of the new worldsParagraph 1 ______(分数:3.12)填空项1:__________________ (正确答案:E)解析:(2).Paragraph 2 ______(分数:3.12)填空项1:__________________ (正确答案:B)解析:(3).Paragraph 3 ______(分数:3.12)填空项1:__________________ (正确答案:C)解析:(4).Paragraph 4 ______(分数:3.12)填空项1:__________________ (正确答案:A)解析:(5).A.its detecting powerB.millions of light years away in spaceC.the location of the VLTD.as an exampleE.the birth of the earthF.the rotation of the earthThe VLT will allow scientists to see events ______.(分数:3.12)填空项1:__________________ (正确答案:B)解析:(6).The designers of the VLT are surprised at ______.(分数:3.12)填空项1:__________________ (正确答案:A)解析:(7).Eta Carinae is taken ______.(分数:3.12)填空项1:__________________ (正确答案:D)解析:(8).Scientists believe the VLT will tell us more about ______.(分数:3.12)填空项1:__________________ (正确答案:E)解析:Ford1.Ford's great strength was the manufacturing process—not invention. Long before he started a car company, he was a worker, known for picking up pieces of metal and wire and turning them into machines. He started putting cars together in 1891. Although it was by no means the firstpopular automobile, the Model T showed the world just how creative Ford was at combining technology and market.2.The company's assembly line alone threw America's Industrial Revolution into overdrive (高速运转). Instead of having workers put together the entire car, Ford's friends, who were great toolmakers from Scotland, organized teams that added parts to each Model T as it moved down a line. By the time Ford's Highland Park plant was humming (嗡嗡作响) along in 1914, the world's first automatic conveyor belt could turn out a car every 93 minutes.3.The same year Henry Ford shocked the world with the $5-a-day minimum wage scheme, the greatest contribution he had ever made. The average wage in the auto industry then was $2.34 for a 9-hour shift. Ford not only doubled that, he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much for doing something that didn't involve an awful lot of training or education. The Wall Street Journal called the plan "an economic crime", and critics everywhere laughed at Ford.4.But as the wage increased later to daily $10, it proved a critical component of Ford's dream to make the automobile accessible (可及的) to all. The critics were too stupid to understand that because Ford had lowered his costs per car, the higher wages didn't matter—except for making it possible for more people to buy cars.(分数:24.96)(1).A.Ford's opponentsB.The assembly lineC.Ford's great dreamD.The establishment of the companyE.Ford's biggest contributionF.Ford's great talentParagraph 1 ______(分数:3.12)填空项1:__________________ (正确答案:F)解析:(2).Paragraph 2 ______(分数:3.12)填空项1:__________________ (正确答案:B)解析:(3).Paragraph 3 ______(分数:3.12)填空项1:__________________ (正确答案:E)解析:(4).Paragraph 4 ______(分数:3.12)填空项1:__________________ (正确答案:C)解析:(5).A.criticized by the mediaB.the low wage in the auto industryC.their lower prices and the higher wagesD.produce cars in large numbersE.the 8-hour shiftF.supported by his friendsThe assembly line made it possible to ______.(分数:3.12)填空项1:__________________ (正确答案:D)解析:(6).Ford was the first to adopt ______.(分数:3.12)填空项1:__________________ (正确答案:E)解析:(7).Ford's cars became available to ordinary people thanks to ______.(分数:3.12)填空项1:__________________ (正确答案:C)解析:(8).Ford's higher-wage and lower-cost strategy was strongly ______.(分数:3.12)填空项1:__________________ (正确答案:A)解析:。

第一篇More Than 8 Hours Sleep Too Much of a Good Thing1Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences.2Investigators at the University of California in San Diego found that people who clock up1 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night‘s sleep than 8-hour sleepers.23These findings, which Dr Daniel Kripke reported in the journal Psychosomatic Medicine3, demonstrate that people who want to get a good ni ght‘s rest may not need to set aside4 more than 8 hours a night He added that ―it might be a good idea‖ for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this.4Previous studies have shown the potential dangers of chronic shortages of sleep — for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.5For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how much they slept during the week and whether they experienced any sleep problems Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall back to sleep, and having fatigue interfere with day-to- day functioning5.6Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed As evidence, he added that one way to help insomnia is to spend less time in bed―It stands to reason6 that if a person spends too long a time in bed, then they‘ll spend a higher percentage of time awake,‖ he said.词汇:refresh / r?‘fre?/ v.(使)精力恢复questionnaire / ,kwest??‘ne?(r)/ n.问卷psych osomatic / ,sa?k??s?‘m?t?k / adj.(指疾病)由精神压力引起的fatigue / f?‘ti:g / n.疲劳caution / ‘k?:??n/ v.警告insomnia / ?n‘s?mn??/ n.失眠habitually / h?‘b?tj??l?, - t??-/ adv.习惯地注释:1.clock up:时间达到2.they had more trouble falling asleep and feeling refr eshed after a night‘s sleep than 8-hour sleepers:falling和feeling都是说明trouble的。

第三部分概括大意和完成句子A Strong Greenhouse Gas1. Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmosphere, it absorbs heat radiating from Earth’s surface.2. With 13 billion cows belching almost constantly around the world, it’s no surprise that methane released by livestock is one of the chief global sources of the gas.3. Greenhouse gases like methane and carbon dioxide make up only a small part of Earth’s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen.4. Atmospheric concentrations of methane have more than double in the last two centuries.5. Cows munch mostly grasses and hay- yet they grow big and hefty.6. That’s why we say livestock gas is also a major factor of causing the global warming.1. paragraph 1 E Methane as a Strong Greenhouse Gas2. Paragraph 2 F Livestock as a Prime Factor of the Greenhouse Effect3. Paragraph 4 C Agriculture Also Contributes to Increased Concentrations of Methane in the Atmosphere4. Paragraph 5 D Why Livestock Releases Methane5. Methane is A one of the major contributors to the intensifying greenhouse effect.6. Greenhouse gases are indispensable to mankind ,but the problem mankind is faced with is B the ever-increasing atmospheric concentrations of greenhouse gases.7. Generally people heap criticism on F big industries and gas-guzzling vehicles for the planet’s temperature rise.8. Nothing has been mentioned in the passage about E how to cut down the cattle populations.Compact Disks1.If someone says to you your music CDs don’t really hold any music on them, andthey only have numbers recorded on them,you may not belive it.2. A small laser beam shines onto the bumps as the CD turns.3.Digital codes are used with many technologies.4.There are many types of compact disks.5.CDs were first sold to the public in 1982.6.Science Keeps on developing.1.paragraph 1&2 D CD’sWorking Principle Is Explained2.paragraph 3 A Digital Code Has Wide Applications3.paragraph 4 F CDs Are of Many Formats4.paragraph 5 C CDs Are Durable5.One advantage of CD-RWs is that they can E be written on and rewritten on likefloppy disks.6.The author predicts it will nor B take many more years before a new technologe isinvented for music recording.7.The laser beam-emitting device and the receiver are considerd to C be the keyparts.8.Space probes could not F keep contact with their ground station efficiently.How We Form First Impression1.We all have first impression of someone we just met.2.The answer is related to how your brain allows you to be aware of the world.3.If you see someone you know and like at school3 ,your brain says “familiar andsafe.”4.When we stereotype people,we use a less mature form of thinkingthat makessimplistic and categorical impressions of others.5.However,if we resist initial stereotypical impressions,we have a chance to beaware of what a person is truly like.1.paragraph 2 D Comparing Incoming Sensory Information Against Memories2.paragraph 3 C IIIustration of First Impression3.paragraph 4 B Comment on First Impression4.paragraph 5 A Ways of Departure from Immature and Simplistic Impressions5.Sensory information is one that is perceived througe E the sights and sounds of theworld6.You interpret D the meaning of incoming sensory information by comparing itagainst the memories already stored in your brain.7.The way we stereotype people is a less mature form of thinking,which is similar toC the immature form of thinking of a cery young child8.We can use our more mature style of thinking thanks to B the most complex areasof our coriex.Icy Microbes1.In ice that has sealed a salty Antarctic lake for more than 2,800 years,scientistshave found frozen bacteria and algae that returned to life after thawing.2. A research team Ied by Peter Doran of the University of lllinots at Chicago drilledthrough more than 39 feet of ice to collect samples of bacteria and algae.3.Doran said the microbes have been age-dated at 2,800 years old,but even oldermicrobes may live deeper in the ice sheet sealing the lake, and in the briny water below the ice.4.Called Lake Vida,the 4.5-square-kilometer body is one of a series of lakes locatedin the McMurdo Dry Valleys of Antarctica,some 2,200kilometers due south2 of New Zealand.5.That prompted the researchers to return in 1996 with equipment to drill a holedown to within a few feet of the water layer.6.The researchers will return in 2004 equipped with instruments that are sterilized.1.paragraph 2 E Antarctic Frozen Life Sampled and Revived.2.paragraph 3 A Significance of Testing Techniques for Sampling Microbes in theDeep Ice Sheet.3.paragraph 4 F Accidental Discovery of Ice-sealed Lake Water in Antarctica.4.paragraph 6 D 2004 Revisit Planned for Collecting Lake Water Specimens.5.Scientists ignored Lake Vide because they thought that a lake of ice B was of littlescientific value.6.Scientists expect that the life, if found in deeper water below the ice sheet,C maybe older than that collected below 39 feet of ice.7.What the scientists will do in 2004 E is to collect some briny lake water foranalysis.8.The salt concentration in the liquid water of Lake Vida A is found to be a greatdeal higher than that of seawater..LED Lighting1 An accidental discovery announced recently has taken LED lighting to a new level, suggesting it could soon offer a cheaper,longer-lasting alternative to the traditional light bulb.2.Michael Bowers,a graduate student2 ai Vanderbilt University,was just trying to make really small quanturn dots,which are crystals generally only a few nanometets big.3.When you shine a light on quanturn dots or apply electricity to them,they react by producing their own light,normally a bright,vibrant color.4.Then Bowers and another student got the idea to stir the dots into polyurethane and coat a blue LED light bulb with the mix.5.LEDsproduce twice as much light as a regular 60 watt bulb and burn fou over 50,000 hours.6.Quanturn dot mixtures could be painted on just about anything5 and electrically excited to produce a rainbow of colors,including white.1. paragraph 1 B LED Lighting WillPeplace Traditional Lighting2. paragraph 3 E Bowers Made an Unexpected Discovery3. paragraph 5 D LED Lighting Has Many Advantages4. paragraph 6 C Almost Everything Could Be the Main Light Source in the Future5.Unlike traditional lighting , LEDs do not give out heat so F LED Light Bulbs Look Lumpy.6.Edison’s bright invention is likely to be outdated because A traditional lighting is less durable and dearer.7.Something unexpected happened during Bower’s experiment when B a laser excited the quantum dots8.Over one quarter of energy consumption for lighting could be saved by 2025 if C America adopted LKEDs.More Than 8 Hours Sleep Too Much of a Good Thing1 Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.2 Investigators at the University of California in San Diego found that people who clock up’9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night.3.These findings,which Dr.Daniel Kripke reported in the journal psychosomatic Medicine3,demonstrate that people who want to get a good night’s rest may not need to set aside4 more than 8 hours a night.4.Previous studies have shown the potential dangers of chronic shortages of sleep-for instance,one report demonstrated that people who habitually sleep less than 7 hourseach night have a higher risk of dying within a fixed period than people who sleep more.5.For the current report,Kripke reviewed the responses of 1,004 adults to sleep question-naires,in which participants indicated how much they slept during the week and whether they experienced any sleep problem.6.Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours.1. paragraph 2 :E.Sleep Problems of Long and Short Sleepers.2. paragraph 4:B.Dangers of Habitual Shoriages of Sleep.3. paragraph 5:A.Kripke’s Research Tool.4. paragraph 6:D.A Way of Overcoming Insomnia.5.To get a good night’s rest,people may not need to F.sleep more than 8 hours.6.Long sleepers are reporied to be more likely to E.suffer sleep problems.7.One of the sleep problems is waking in the middle of the night, unable to A.fall asleep again.8.One survey showed that people who habitually C.sleep less than 7 hours each night have a higher risk of dying.More Rural Research Is Needed1.Agricultural research funding is vital if the world is to feed itself better than itdoes now.2.“The global decline in investment in international agricultural research must bereversed if significant progress is to be made towards reducing malnutrition and poverty , ” he said.3.Research is needed to solve food production, land degradation2 and environmentalproblems.4.The developing world was investing about 0.5%,or $8 billion a year , of itsagricultural gross domestic product(GDP) on5 research, and the developed world was spending 2.5%of its GDP .5.He said crop research could produce technologies that spread across manycountries, such as wheat production research having spin-offs Mexico, China or India6 .6.“Technologies still need to be refined for the local conditions but a lot of thestrategic research can have global application, so that money can be used very efficiently, ” Dr. Fischer said.7.Yields of rice, wheat and maize have grown impressively in the past 30 years,especially in developing countries.1.paragraph 1 E Increase in Investment on Agricultural

research from NASA scientists suggests emissions of black soot alter the way sunlight reflects off snow.2.Soot in the higher latitudes of the Earth,where ice is more common,absorbs more of the sun’s energy and warmth than an icy,white background.3.Soot in areas with snow and ice may play an important role in climate change.4.Hansen found soot’s effect on snow albedo(solar energy reflected back to space),which1may be contributing to trends toward early springs in the Northen Hemisphere,such as thinning Arctic sea ice,melting glaciers and permafrost.5.”Black carbon reduces the amount of energy reflected by snow back into space,thus hesting the snow furface more than if there were no black carbon2,”Hansen said.6.Hansen cautioned,although the role of soot in altering global climate is substantial,it does not alter the fact that greenhouse gases are the primary cause of climate warming during the past century.7.The researchers found that observed warming in the Northern Hemisphere was large in the winter and spring at middle and high latitudes.1. paragraph 3:C Explanation of Increased Warming Effect Caused by Soot.2. paragraph 4:A Soot’s Role in Changes in the Climate and the Atmosphere.3. paragraph 6:F Greenhouse Gases as the Main Factor of Global Warming.4. paragraph 7:B Observations of Warming in the Climate and the Atmosphere.5. In the twentieth century, soot B contributed to 25 percent of observed global warming.6. Hansen cautioned that greenhouse gases E still surpass soot in warming the world’s climate during the last century.7. Black soot covered snow and ice D absorb more of sun’s energy and warmth than white background.8.A soot forcing is unusually effective,which A produces much more global warming than a carbon-dioxide forcing of the same magnitude.Screen Test1.Every year millions of women are screened with X-rays to pick up signs of breastcancer.2.But the medical benefits of screening these younger women arecontroversial,partly because the radiation brings a small risk of inducing cancer. 3.Researchers at the Polytechnic University1 of Valencia analysed the effect ofscreening more than 160,000 women at 11 local clinis.4.The mathematical model recommended by Britain’s National RadillogicalProtection Board predicted that the screening programme would cause 36cancers per 100,000women,18 of them fatal.5.The researchers argue that the level of radiation-induced cancers is “not verysignificant” compared to the far larger number of cancers that are discovered andtreated.6.But they, point out that the risk of women contracting canver from radiation couldbe reduced by between 40 and 80 percent if screening began at 50 instead of 45,because they would be exposed to less radiation.7.“There is a trade-off between the diagnostic benefits of breast screening and itsrisks,”admits Michael Clark of the NRPB.1.paragraph 2 A Harm Screening May Do to a Younger Woman2.paragraph 3B Investigating the Effect of Screening3.paragraph 4 C Effect Predicted by Two Differernt Models4.paragraph 5D Small Risk of Inducing Cancers from Radiation5.Early discovery of breast cancer may C save a life6.Advantages of screening women under 50 are D still open to debate7.Delaying the age at which screening staris may E reduce the risk of radiationtriggering a cancer8.Radiation exposure should be F reduced to the minimumThe Mir Space Station1.The Russian Mir Space Station ,which came down in 2001 at last after 15 years ofpioneering the concept of long-term human space flight, is remembered for its accomplishments in the human space flight history.2.During Mir’s lifetime, Russia spent about US $4.2 billion to build and maintainthe station .3.The Soviet Union launched Mir, which was designed to last from three to fiveyears, on February 20,1986, and housed 104 astronauts over 12 years and seven months, most of whom were not Russian.4.The more than 400 million the United States provided Russian for the visits notonly kept Mir operating, but also gave the Americans and their partners in the international station project valuable experience in long-term flight and multinational operations.5. A debate continues over Mir’s contributions to science.6.Despite the many firsts Mir accomplished,1997 was a bad year out of 15 for Mir.7.Most of these problems were repaired, with American help and suppliers, butMir’s reputation as a space station was ruined.8.Mir’s setbacks are nothing, though5 ,when we compare them with itsaccomplishments.1.paragraph 4 B Rewards Following the US Financial Injection2.paragraph 5 E Mir’s Firsts in Scientific Experiments and Space Exploration3.paragraph 6 C Mir’s problem Year4.paragraph 8 A Undeniable Mir’s Achievements5.Mir enhanced the confidence in the scientists that humans living in space for along time was F quite possible6.In Mir, the US astronauts created E many firsts7.When we think of Mir in terms of its achievements, its setbacks are D nothing8.The writer tends to think that Mir was B a great successThe Tiniest Electric Motor in the World1.Scientists recently made public the tiniest electric motor ever1 built.2.The motor works by shuffling atoms between two molten metal droplets in acarton nanotube..3.The technique exploits the fact that surface tension-the tendency of atoms ormolecules to resist separating-becomes more important at small scales.4.Although the amount of energy produced is small-20 microwatts-it is quiteimpressive in relation to the tiny scale of the motor.5.In 1988,Professor Richard Muller and colleagues made the first operatingmicromotor, which was 100 microns across, or about the thickness of a human hair.6.Nanotechnology engineers try to mimic nature, building things atom-by-atom.1.paragraph 2 E The Working Principle of the Nanomotor2.paragraph 4 B A Description of the Nanomotor in Terms of Power and Size3.paragraph 5 D Previous Inventions of Nanoscale Products4.paragraph 6 F Possible Fields of Application in the Future5.Doctors envision that the nanomotor would travel through human bodies to Aremove disease6.Surface tension means the tendency of atoms or molecules to B resist separating7.Nanoconveyors could be used to F transport nanoscale objects.8.Applying a small electric current causes atoms to C shuffle between two moltenmetal dropletsWashoe Learned American Sign Language1.An animal that influenced scientific thought has died.2.Research scientists Allen and Beatrix Gardner began teaching Washoe signlanguage in 1966.3.However, critics argued Washoe only learned to repeat sign language movementfrom watching her teachers.4.Scientists like private researcher Jane Goodall believe8 Washoe provided newinformation about the mental workings of chimpanzees.5.Debate continues about chimps’ understanding of human communication .1.paragraph 1 C General Information about Washoe2.paragraph 2 B Report about Washoe ’s Progress in learning Sign Language3.paragraph 3 E Debate on Chimps’ Intelligence4.paragraph 4 A Reason Why Not Many Scientists Carry out This ResearchNowadays.5.Washoe could make signs to communicate C when she wanted to eat6.Some scientists doubted A if the Gardener’s argument was sound7.Washoe taught three younger chimps sign language D while she was at a researchcenter in Ellensburg.8.The experimenters thought Washoe was intelligent E because she could use signlanguage to ask for fruits。

More Rural Research Is Needed
1 Agricultural research funding is vital if the world is to feed itself better than it does now. Dr. Tony Fischer, crop scientist, said demand was growing at 2.5% per year, but with modern technologies and the development of new ones, the world should be able to stay ahead1。
2 “The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reducing malnutrition and poverty,” he said.
3 Research is needed to solve food production, land degradation2 and environmental problems. Secure local food supplies3 led to economic growth which, in turn, slowed population growth. Dr. Fischer painted a picture of the world’s ability to feed itself in the first 25 years, when the world’s population is expected to rise from 5.8 to 8 billion people. He said that things will probably hold or improve
4 but there’ll still be a lot of hungry people. The biggest concentration of poor and hungry people would be in sub-Saharan Afiica and southern Asia in 2020, similar to the current pattern. If there is any change, a slight improvement will be seen in southern Asia, but not in sub-Saharan Afiica. The major inqjrovement will be in East Asia, South America and South-East Asia.
4 The developing world was investing about 0.5%, or $8 billion a year, of its agricultural gross domestic product (GDP) on
5 research, and the developed world was spending 2.5% of its GDP. Dr. Fischer said more was needed from all countries.
5 He said crop research could produce technologies that spread across many countries, such as wheat production research having spin-offs for Mexico, China or India6.
6 “Technologies still need to be refined for the local conditions but a lot of the strategic research can have global application, so that money can be used very efficiently,” Dr. Fischer said.。
