Irradiation of other meats, such as beef and lamb, is being reviewed. Federal approval does not require that industry adopt the process, and few food processors presently offer irradiated products. Market studies have shown that many consumers are afraid that eating irradiated foods may cause cancer, despite scientific studies that prove the safety of treated foods. Some people argue that more severe government inspection, higher food-safety standards, and more careful-preparation practices by consumers are all that is needed to ensure that food is safe. Consequently, companies currently see no need to spend millions of dollars outfitting processing plants with the equipment necessary for a process that very few shoppers are in favor of. All supermarkets that sell irradiated food must label the food either directly on the packaging, or, in the case of bulk items like fruits and vegetables, by placing a sign nearby. There is no requirement for the labeling of irradiated food served by chain restaurants or hospitals that buy directly from distributors, nor any regulations for products that contain irradiated ingredients. Presently, the FDA allows food to be treated with three types of radiation -- gamma rays, high-energy electrons, and X rays -- and sets limits on doses, depending on the type of food. The principle is that the dose to be used for a certain type of food should not exceed the amount that is sufficient to kill most harmful insects and bacteria present in it. Different types of food, because of their molecular compositions, may require different doses of radiation. According to the passage, killing insects and bacteria present in foods by irradiating is not completely approved by the US government. A．Right B．Wrong C．Not mentioned
17、 There are quite a number of food processors which are interested in producing irritated foods. A．Right B．Wrong C．Not mentioned
18、 Some consumers are doubtful of the safety of irradiated foods and suggest a more severe government inspection be taken. A．Right B．Wrong C．Not mentioned
19、 Some companies foresee the promising future of setting up food processing factories, although they do not see the need now. A．Right B．Wrong C．Not mentioned
20、 It is required that labels placed on irradiated food or nearby bulk items such as vegetables and fruits should indicate irradiated ingredients. A．Right B．Wrong C．Not mentioned
21、 Restaurants can serve irradiated food bought directly from distributors without labeling it. A．Right B．Wrong C．Not mentioned
22、 The passage tells us that FDA approves irradiating food to some extent but irradiated food is not widely accepted. A．Right B．Wrong C．Not mentioned 第3部分：概括大意與完成句子(第23-30題，每題1分，共8分)下面的短文后有2項測試任務(wù)：(1)第23～26題要求從所給的6個選項中為第2～5段每段選擇1個標(biāo)題；(2)第27～30題要求從所給的6個選項中為每個句子確定1個選項。 23、回答23-30題： Maglev Trains A few countries are using powerful electromagnets to develop high-speed trains, called maglev trains. Maglev is short for magnetic levitation1, which means that these trains float over a guide way using the basic principles of magnets to replace the old steel wheel and track trains. If you’ve ever played with magnets, you know that opposite poles attract and like poles repel each other. This is the basic principle behind electromagnetic propulsion. Electromagnets are similar to other magnets in that they attract metal objects, but the magnetic pull is temporary. You can easily create a small electromagnet yourself by connecting the ends of a copper wire to the positive and negative ends of an AA-cell battery. This creates a small magnetic field. If you disconnect either end of the wire from the battery, the magnetic field is taken away. The magnetic field created in this wire-and-battery experiment is the simple idea behind a maglev train rail system. There are three components to this system: A large electrical power source, metal coils lining a guide way or track, and large guidance magnets attached to the underside of the train. The big difference between a maglev train and a conventional train is that maglev trains do not have an engine-at least not the kind of engine used to pull typical train cars along steel tracks4. The engine for maglev trains is rather innoticeable. Instead of using fossil fuels, the magnetic field created by the electrified coils in the guideway walls and the track combines to propel the trains. The magnetized coil running along the track, called a guideway, repels the large magnets on the train’s undercarriage, allowing the train to levitate between 1 to 10 cm above the guideway. Once the train is levitated, power is supplied to the coils within the guideway walls to create a unique system of magnetic fields that pull and push the train along the guideway. The electric current supplied to the coils in the guideway walls is constantly alternating to change the polarity of the magnetized coils. This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust. Maglev trains float on a cushion of air, eliminating friction. This lack of friction allows these trains to reach unprecedented ground transportation speeds of more than 500 kph, or twice as fast as the fastest conventional train. At 500 kph, you could travel from Paris to Rome in just over two hours. Paragraph 3 _____
24、 Paragraph 4 _____
25、 Paragraph 5 _____
26、 Paragraph 6 _____ A．The Main Components of the Maglev Train System B．High-speed Maglev due to Zero Friction C．The Working Principle of the Maglev Train D．Differences between Polarity and Magnetic Field E．Comparison of Maglev Trains with Traditional Ones F．Maglev with a Powerful Motor
27、 Several countries in the world are using strong electromagnets _____.
28、 You can connect a wire to the positive and negative ends of a battery _____.
29、 A unique system of magnetic fields is created by the coils _____.
30、 The frictionless maglev train enables you _____. A．to develop a maglev train rail system B．to explain why maglev trains are faster C．to pull and push the train forward D．to create a magnetic field E．to experiment with the maglev train F．to travel from Paris to Rome in about two hours 第4部分：閱讀理解(第31-45題，每題3分，共45分)下面有3篇短文，每篇短文后有5道題。請根據(jù)短文內(nèi)容，為每題確定1個選項。 31、回答31-45題： Why Are America's Kids So Stressed I'm usually fairly skeptical about any research that concludes that people are either happieror unhappier or more or less certain of themselves than they were 50 years ago. While any ofthese statements might be true, they are practically impossible to prove scientifically. Still, Iwas struck by a report which concluded that today's children are significantly more anxious thanchildren in the 1950s. In fact, the analysis showed, normal children ages 9 to 17 exhibit ahigher level of anxiety today than children who were treated for mental illness 50 years ago. Why are America's kids so stressed? The report cites two main causes: increasing physicalisolation -- brought on by high divorce rates and less involvement in community, among otherthings -- and a growing perception that the world is a more dangerous place. Given that we can't turn the clock back, adults can still do plenty to help the next generation cope. At the top of the list is nurturing a better appreciation of the limits of individualism. Nochild is an island. Strengthening social ties helps build communities and protect individualsagainst stress. To help kids build stronger connections with others, you can pull the plug on TVs andcomputers. Your family will thank you later. They will have more time for face-to-facerelationships, and they will get more sleep. Limit the amount of virtual violence your children are exposed to. It's not just video games and movies; children see a lot of murder and crime on the local news. Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale. Make exercise part of your daily routine. It will help you cope with your own anxieties andprovide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn't have toruin your life. The author thinks that the conclusions of any research about people's state of mind are_______. A．surprising B．confusing C．illogical D．questionable
32、 What does the author mean when he says, "we can't turn the clock back"? A．It's impossible to slow down the pace of change. B．The social reality children are facing cannot be changed. C．Lessons learned from the past should not be forgotten. D．It's impossible to forget the past.
33、 According to an analysis, compared with normal children today, children treated as mentally ill 50 years ago_______. A．were less isolated physically B．were probably less self-centered C．probably suffered less from anxiety D．were considered less individualistic
34、 The first and most important thing parents should do to help their children is_______. A．to provide them with a safer environment B．to lower their, expectations for them C．to get them more involved socially D．to set a good model for them to follow
35、 What conclusion can be drawn from the passage? A．Anxiety, though unavoidable, can be coped with. B．Children's anxiety has been enormously exaggerated. C．Children's anxiety can be eliminated with more parental care. D．Anxiety, if properly controlled, may help children become mature.
36、回答36-50題： Clone Farm Factory farming could soon enter a new era of mass production. Companies in the US aredeveloping the technology needed to "clone" chickens on a massive scale. Once a chicken withdesirable traits has been bred or genetically engineered tens of thousands of eggs, which willhatch into identical copies, could roll off the production lines every hour. Billions of clonescould be produced each year to supply chicken farms with birds that all grow at the same rate,have the same amount of meat and taste the same. This, at least, is the vision of the US's National Institute of Science and Technology,which has given Origen, Therapeutics of Burlingame, California, and Embrex of North CarolinaUSD 4. 7 million to help fund research. The prospect has alarmed animal welfare groups, whofear it could increase the suffering of farm birds. That's unlikely to put off the poultry industry, however, which wants disease-resistant birds that grow faster on less food. "Producers would like the same meat quantity but to use reducedinputs to get there", says Mike Fitzgerald of Origen. To meet this demand, Origen aims to"create an animal that is effectively cloned", he says. Normal cloning doesn't work in birdsbecause eggs can't be removed and implanted. Instead, the company is trying to bulk-growembryonic stem cells taken from fertilized eggs as soon as they're laid. "The trick is to culturethe cells without them starting to distinguish, so they remain pluripotent", says Fitzgerald. Using a long-established technique, these donor ceils will then be injected into the embryoof a freshly laid, fertilized recipient egg, forming a chick that is a "chimera". Strictly speakinga chimera isn't a clone, because it contains cells from both donor and recipient. But Fitzgeraldsays it will be enough, say, 95 percent of a chicken's body develops from donor cells. "In thepoultry world, it doesn't matter if it's not 100 percent," he says. Another challenge for Origen is to scale up production. To do this, it has teamed up with"Embrex, which produces machines that can inject vaccines into up to 50, 000 eggs an hour.Embrex is now trying to modify the machines to locate the embryo and inject the cells intoprecisely the right spot without killing it. In future, Origen imagines freezing stem cells from different strains of chicken. If orderscome in for a particular strain, millions of eggs could be produced in months or even weeks. Atpresent, maintaining all the varieties the market might call for is too expensive for breeders, andit takes years to breed enough chickens to produce the billions of eggs that farmers need. Which statement is the best description of the new era of factory farming according to the first paragraph? A．Eggs are all genetically engineered. B．Thousands of eggs are produced every hour, C．Cloned chickens are bulk-produced with the same growth rate, weight and taste. D．Identical eggs can be hatched on the production lines.
37、 Which institution has offered USD 4. 7 million to fund the research? A．The US's National Institute of Science and Technology. B．Origen Therapeutics of Burlingame, California. C．Embrex of North Carolina. D．Animal welfare groups.
38、 In the third paragraph, by saying " Producers would like the same meat quantity but to use reduced inputs to get there" Mike Fitzgerald means that he wishes A．chickens' quality could be maintained but with less investment B．chickens' taste could be improved but at less costs C．chickens' growth rate could be quickened but with less inputs D．chickens could grow to the same weight but with less feed
39、 Which of the following statements about Origen and Embrex is correct according to the fifth paragraph? A．Origen and Embrex will jointly invent machines to increase production. B．Origen wants to purchase an efficient donor cell-injecting machine. C．Origen has joined hands with Embrex in producing cell-injecting machines. D．Origen is the leading company in producing embryo-locating machines.
40、 The technology of freezing stem cells from different strains of chicken can do all the following EXCEPT that A．farmers can order certain strains of chicken only B．Origen can supply all the strains of chicken the market might need C．chicken farmers order certain strains of chicken for economic reasons D．chicken farmers can be supplied with whatever they need
41、回答41-55題： Small But Wise On December 14, NASA blasted a small but mighty telescope into space. The telescope is called WISE and is about as wide around as a trashcan. Don’t let its small size fool you: WISE has a powerful digital camera, and it will be taking pictures of some the wildest objects in the known universe,including asteroids, faint stars, blazing galaxies and giant clouds of dust where planets and stars are born. “I’m very excited because we’re going to be seeing parts of the universe that we haven’t seen before,” said Ned Wright, a scientist who directs the WISE project. Since arriving in space, the WISE telescope has been circling the Earth, held by gravity in a polar orbit (this means it crosses close to the north and south poles with each lap). Its camera is pointed outward, away from the Earth, and WISE will snap a picture of a different part of the sky every 11 minutes. After six months it will have taken pictures across the entire sky. The pictures taken by WISE won’t be like everyday digital photographs, however. WISE stands for “Wide-field Infrared Survey Explorer.” As its name suggests, the WISE camera takes pictures of features that give off infrared radiation. Radiation is energy that travels as a wave. Visible light, including the familiar spectrum of light that becomes visible in a rainbow,is an example of radiation. When an ordinary digital camera takes a picture of a tree, for example, it receives the waves of visible light that are reflected off the tree. When these waves enter the camera through the lens, they’re processed by the camera, which then puts the image together. Waves of infrared radiation are longer than waves of visible light, so ordinary digital cameras don’t see them, and neither do the eyes of human beings. Although invisible to the eye, longer infrared radiation can be detected as warmth by the skin. That’s a key idea to why WISE will be able to see things other telescopes can’t. Not everything in the universe shows up in visible light. Asteroids, for example, are giant rocks that float through space-but they absorb most of the light that reaches them. They don’t reflect light, so they’re difficult to see. But they do give off infrared radiation, so an infrared telescope like WISE will be able to produce images of them. During its mission WISE will take pictures of hundreds of thousands of asteroids. Brown dwarfs are another kind of deep-space object that will show up in WISE’s pictures. These objects are “failed” stars-which means they are not massive enough to jump start the same kind of reactions that power stars such as the sun. Instead,brown dwarfs simply shrink and cool down. They’re so dim that they’re almost impossible to see with visible light, but in the infrared spectrum they glow. What is so special about WISE? A．It is small in size but carries a large camera. B．It is as small as a trashcan. C．Its digital camera can help astronomers to see the unknown space. D．Never before has a telescope carried a digital camera in space.
42、 Which is NOT the synonym for the word "snap" in the third paragraph? A．make. B．shoot. C．take D．photograph.
43、 The camera on WISE _____ A．is no different from an ordinary camera. B．does not see infrared radiation while the ordinary camera does. C．catches the infrared radiation while the ordinary camera does not. D．reflects light that human eyes can see.
44、 Which of the following is NOT correct about “asteroids” according to paragraph 7? A．Asteroids float through space giving off visible light. B．Asteroids do not reflect light that reaches them. C．It is difficult to take asteroids’ pictures by ordinary cameras. D．The WISE telescope can take pictures of asteroids
45、 What is implied in the last paragraph? A．Brown dwarfs give off visible light. B．Brown dwarfs give off infrared radiation. C．Brown dwarfs are power stars like the sun. D．Brown dwarfs are impossible to see with the WISE telescope. 第5部分：補全短文(第46～50題，每題2分，共10分)下面的短文有5處空白，短文后有6個句子，其中5個取自短文，請根據(jù)短文內(nèi)容將其分別放回原有位置，以恢復(fù)文章原貌。 46、回答46-50題： Mergers The most common kind of consolidation today is the merger. A merger occurs ____(1)____. With the deregulation of natural gas, the nation’s 20 interstate pipeline companies became fearful of cutthroat competition. Some felt that they could increase their efficiency and improve their market flexibility by merging. In 1985 Internorth of Omaha paid $2.3 billion for Houston Natural Gas Corporation, ____(2)____. The system connected markets from coast to coast and raised sales to $10 billion. On occasion, mergers have occurred between smaller companies in an industry dominated by a few giant firms. These smaller companies claim that they need to merge to become more efficient and effective in competing against the biggest corporations. They maintain that such action increases competition instead of reducing it. The Antitrust Division of the Justice Department has not always agreed with them. Four major waves of mergers have taken place in this country. The first started in 1887, just prior to the passage of the Sherman Antitrust Act, and ended in 1904. It involved such giants as United States Steel and Standard Oil trying to create monopolies in their industries. From the end of World War I until the 1930s, large firms swallowed smaller firms to create oligopolies. The monopoly had no chance and the oligopoly little chance of succeeding today under present antitrust policy. The third major merger movement began in the 1960s, reached a peak in 1969, ____(3)____. Many of the acquisitions involved giant firms in one industry buying up large companies in totally unrelated industries. Such mergers are called conglomerate mergers. A classic example is Mobil Oil Corporation’s purchase of the huge retail chain Montgomery Ward & Company. Mergers in the last ten years were in the thousands. More important is the value of the transactions, which has risen sharply. The number of mergers and acquisitions apply ____(4)____. The petroleum industry had mergers and acquisitions valued at closed to $80 billion between 1981 and 1984. Other industries ____(5)____ were banking and finance, insurance, mining and mineral, processed foods. A．thereby gaining control of the world’s longest pipeline B．a(chǎn)nd then gradually declined C．experiencing large takeovers D．resulting in combinations of small firms E．only to those valued at $100 million or more F．when two or more companies get together to form one company ________

While any ofthese statements might be true, they are practically impossible to prove scientifically. Still, Iwas struck by a report which concluded that today's children are significantly more anxious thanchildren in the 1950s. In fact, the analysis showed, normal children ages 9 to 17 exhibit ahigher level of anxiety today than children who were treated for mental illness 50 years ago. Why are America's kids so stressed? The report cites two main causes: increasing physicalisolation -- brought on by high divorce rates and less involvement in community, among otherthings -- and a growing perception that the world is a more dangerous place. Given that we can't turn the clock back, adults can still do plenty to help the next generation cope. At the top of the list is nurturing a better appreciation of the limits of individualism. Nochild is an island. Strengthening social ties helps build communities and protect individualsagainst stress. To help kids build stronger connections with others, you can pull the plug on TVs andcomputers. Your family will thank you later. They will have more time for face-to-facerelationships, and they will get more sleep. Limit the amount of virtual violence your children are exposed to. It's not just video games and movies; children see a lot of murder and crime on the local news. Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale. Make exercise part of your daily routine. It will help you cope with your own anxieties andprovide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn't have toruin your life. The author thinks that the conclusions of any research about people's state of mind are_______. A．surprising B．confusing C．illogical D．questionable
32、 What does the author mean when he says, "we can't turn the clock back"? A．It's impossible to slow down the pace of change. B．The social reality children are facing cannot be changed. C．Lessons learned from the past should not be forgotten. D．It's impossible to forget the past.
33、 According to an analysis, compared with normal children today, children treated as mentally ill 50 years ago_______. A．were less isolated physically B．were probably less self-centered C．probably suffered less from anxiety D．were considered less individualistic
34、 The first and most important thing parents should do to help their children is_______. A．to provide them with a safer environment B．to lower their, expectations for them C．to get them more involved socially D．to set a good model for them to follow
35、 What conclusion can be drawn from the passage? A．Anxiety, though unavoidable, can be coped with. B．Children's anxiety has been enormously exaggerated. C．Children's anxiety can be eliminated with more parental care. D．Anxiety, if properly controlled, may help children become mature.
36、回答36-50題： Clone Farm Factory farming could soon enter a new era of mass production. Companies in the US aredeveloping the technology needed to "clone" chickens on a massive scale. Once a chicken withdesirable traits has been bred or genetically engineered tens of thousands of eggs, which willhatch into identical copies, could roll off the production lines every hour. Billions of clonescould be produced each year to supply chicken farms with birds that all grow at the same rate,have the same amount of meat and taste the same. This, at least, is the vision of the US's National Institute of Science and Technology,which has given Origen, Therapeutics of Burlingame, California, and Embrex of North CarolinaUSD 4. 7 million to help fund research. The prospect has alarmed animal welfare groups, whofear it could increase the suffering of farm birds. That's unlikely to put off the poultry industry, however, which wants disease-resistant birds that grow faster on less food. "Producers would like the same meat quantity but to use reducedinputs to get there", says Mike Fitzgerald of Origen. To meet this demand, Origen aims to"create an animal that is effectively cloned", he says. Normal cloning doesn't work in birdsbecause eggs can't be removed and implanted. Instead, the company is trying to bulk-growembryonic stem cells taken from fertilized eggs as soon as they're laid. "The trick is to culturethe cells without them starting to distinguish, so they remain pluripotent", says Fitzgerald. Using a long-established technique, these donor ceils will then be injected into the embryoof a freshly laid, fertilized recipient egg, forming a chick that is a "chimera". Strictly speakinga chimera isn't a clone, because it contains cells from both donor and recipient. But Fitzgeraldsays it will be enough, say, 95 percent of a chicken's body develops from donor cells. "In thepoultry world, it doesn't matter if it's not 100 percent," he says. Another challenge for Origen is to scale up production. To do this, it has teamed up with"Embrex, which produces machines that can inject vaccines into up to 50, 000 eggs an hour.Embrex is now trying to modify the machines to locate the embryo and inject the cells intoprecisely the right spot without killing it. In future, Origen imagines freezing stem cells from different strains of chicken. If orderscome in for a particular strain, millions of eggs could be produced in months or even weeks. Atpresent, maintaining all the varieties the market might call for is too expensive for breeders, andit takes years to breed enough chickens to produce the billions of eggs that farmers need. Which statement is the best description of the new era of factory farming according to the first paragraph? A．Eggs are all genetically engineered. B．Thousands of eggs are produced every hour, C．Cloned chickens are bulk-produced with the same growth rate, weight and taste. D．Identical eggs can be hatched on the production lines.
37、 Which institution has offered USD 4. 7 million to fund the research? A．The US's National Institute of Science and Technology. B．Origen Therapeutics of Burlingame, California. C．Embrex of North Carolina. D．Animal welfare groups.
38、 In the third paragraph, by saying " Producers would like the same meat quantity but to use reduced inputs to get there" Mike Fitzgerald means that he wishes A．chickens' quality could be maintained but with less investment B．chickens' taste could be improved but at less costs C．chickens' growth rate could be quickened but with less inputs D．chickens could grow to the same weight but with less feed
39、 Which of the following statements about Origen and Embrex is correct according to the fifth paragraph? A．Origen and Embrex will jointly invent machines to increase production. B．Origen wants to purchase an efficient donor cell-injecting machine. C．Origen has joined hands with Embrex in producing cell-injecting machines. D．Origen is the leading company in producing embryo-locating machines.
40、 The technology of freezing stem cells from different strains of chicken can do all the following EXCEPT that A．farmers can order certain strains of chicken only B．Origen can supply all the strains of chicken the market might need C．chicken farmers order certain strains of chicken for economic reasons D．chicken farmers can be supplied with whatever they need
41、回答41-55題： Small But Wise On December 14, NASA blasted a small but mighty telescope into space. The telescope is called WISE and is about as wide around as a trashcan. Don’t let its small size fool you: WISE has a powerful digital camera, and it will be taking pictures of some the wildest objects in the known universe,including asteroids, faint stars, blazing galaxies and giant clouds of dust where planets and stars are born. “I’m very excited because we’re going to be seeing parts of the universe that we haven’t seen before,” said Ned Wright, a scientist who directs the WISE project. Since arriving in space, the WISE telescope has been circling the Earth, held by gravity in a polar orbit (this means it crosses close to the north and south poles with each lap). Its camera is pointed outward, away from the Earth, and WISE will snap a picture of a different part of the sky every 11 minutes. After six months it will have taken pictures across the entire sky. The pictures taken by WISE won’t be like everyday digital photographs, however. WISE stands for “Wide-field Infrared Survey Explorer.” As its name suggests, the WISE camera takes pictures of features that give off infrared radiation. Radiation is energy that travels as a wave. Visible light, including the familiar spectrum of light that becomes visible in a rainbow,is an example of radiation. When an ordinary digital camera takes a picture of a tree, for example, it receives the waves of visible light that are reflected off the tree. When these waves enter the camera through the lens, they’re processed by the camera, which then puts the image together. Waves of infrared radiation are longer than waves of visible light, so ordinary digital cameras don’t see them, and neither do the eyes of human beings. Although invisible to the eye, longer infrared radiation can be detected as warmth by the skin. That’s a key idea to why WISE will be able to see things other telescopes can’t. Not everything in the universe shows up in visible light. Asteroids, for example, are giant rocks that float through space-but they absorb most of the light that reaches them. They don’t reflect light, so they’re difficult to see. But they do give off infrared radiation, so an infrared telescope like WISE will be able to produce images of them. During its mission WISE will take pictures of hundreds of thousands of asteroids. Brown dwarfs are another kind of deep-space object that will show up in WISE’s pictures. These objects are “failed” stars-which means they are not massive enough to jump start the same kind of reactions that power stars such as the sun. Instead,brown dwarfs simply shrink and cool down. They’re so dim that they’re almost impossible to see with visible light, but in the infrared spectrum they glow. What is so special about WISE? A．It is small in size but carries a large camera. B．It is as small as a trashcan. C．Its digital camera can help astronomers to see the unknown space. D．Never before has a telescope carried a digital camera in space.
42、 Which is NOT the synonym for the word "snap" in the third paragraph? A．make. B．shoot. C．take D．photograph.
43、 The camera on WISE _____ A．is no different from an ordinary camera. B．does not see infrared radiation while the ordinary camera does. C．catches the infrared radiation while the ordinary camera does not. D．reflects light that human eyes can see.
44、 Which of the following is NOT correct about “asteroids” according to paragraph 7? A．Asteroids float through space giving off visible light. B．Asteroids do not reflect light that reaches them. C．It is difficult to take asteroids’ pictures by ordinary cameras. D．The WISE telescope can take pictures of asteroids
45、 What is implied in the last paragraph? A．Brown dwarfs give off visible light. B．Brown dwarfs give off infrared radiation. C．Brown dwarfs are power stars like the sun. D．Brown dwarfs are impossible to see with the WISE telescope. 第5部分：補全短文(第46～50題，每題2分，共10分)下面的短文有5處空白，短文后有6個句子，其中5個取自短文，請根據(jù)短文內(nèi)容將其分別放回原有位置，以恢復(fù)文章原貌。 46、回答46-50題： Mergers The most common kind of consolidation today is the merger. A merger occurs ____(1)____. With the deregulation of natural gas, the nation’s 20 interstate pipeline companies became fearful of cutthroat competition. Some felt that they could increase their efficiency and improve their market flexibility by merging. In 1985 Internorth of Omaha paid $2.3 billion for Houston Natural Gas Corporation, ____(2)____. The system connected markets from coast to coast and raised sales to $10 billion. On occasion, mergers have occurred between smaller companies in an industry dominated by a few giant firms. These smaller companies claim that they need to merge to become more efficient and effective in competing against the biggest corporations. They maintain that such action increases competition instead of reducing it. The Antitrust Division of the Justice Department has not always agreed with them. Four major waves of mergers have taken place in this country. The first started in 1887, just prior to the passage of the Sherman Antitrust Act, and ended in 1904. It involved such giants as United States Steel and Standard Oil trying to create monopolies in their industries. From the end of World War I until the 1930s, large firms swallowed smaller firms to create oligopolies. The monopoly had no chance and the oligopoly little chance of succeeding today under present antitrust policy. The third major merger movement began in the 1960s, reached a peak in 1969, ____(3)____. Many of the acquisitions involved giant firms in one industry buying up large companies in totally unrelated industries. Such mergers are called conglomerate mergers. A classic example is Mobil Oil Corporation’s purchase of the huge retail chain Montgomery Ward & Company. Mergers in the last ten years were in the thousands. More important is the value of the transactions, which has risen sharply. The number of mergers and acquisitions apply ____(4)____. The petroleum industry had mergers and acquisitions valued at closed to $80 billion between 1981 and 1984. Other industries ____(5)____ were banking and finance, insurance, mining and mineral, processed foods. A．thereby gaining control of the world’s longest pipeline B．a(chǎn)nd then gradually declined C．experiencing large takeovers D．resulting in combinations of small firms E．only to those valued at $100 million or more F．when two or more companies get together to form one company ________
