Section BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(C)Crude awakeningA battle between two energy exchanges[1] OPEN-OUTCRY trading is supposed to be an odd, outdated practice, rapidly being replaced by sleeker, cheaper electronic systems. Try telling that to the New York Mercantile Exchange (NYMEX), the world’s largest commodities exchange. On November 1st the NYMEX opened an open-outcry pit(公开叫价交易厅)in Dublin to handle Brent crude futures(布伦特原油期货), the benchmark(基准)contract for pricing two-thirds of the world’s oil.[2] The NYMEX is trying to grab liquidity from London’s International Petroleum Exchange (IPE), which trades the most Brent contracts; the New York exchange has so far concentrated on West Texas Intermediate, an American bench mark grade. The new pit is a response to the IPE’s efforts to modernise. On the same day as NYMEX traders started shouting Brent prices in Dublin, the IPE did away with its morning open-outcry session: now such trades must be electronic, or done in the pit after lunch.[3] The New York exchange claims that customers, such as hedge funds (对冲基金) or energy companies, prefer open-outcry because it allows for more liquidity. Although most other exchanges are heading in the opposite direction, in commodity markets such as the NYMEX, pressure from “locals”--self-employed traders--is helping to support open-outcry, although some think that customers pay up to five times as much as with electronic systems. Even the IPE has no plans to close its floor. Only last month it signed a rental agreement, lasting until 2017, for its trading floor in London.[4] Dublin’s new pit is “showing promise”, says Rob Laughlin, a trader with Man Financial, despite a few technical glitches. On its first day it handled 5,726 lots of Brent (each lot, or contract, is 1,000 barrels), over a third of the volume in the IPE’s new morning electronic session. By the year’s end, predicts Mr Laughlin, it should be clear whether the venture will be feasible. Itwould stand a better chance if it moved to London. It may yet: it started in Ireland because regulatory approval could be obtained faster there than in Britain.[5] In the long run having both exchanges offering similar contracts will be unsustainable (不可持续的). Stealing liquidity from an established market leader, as the NYMEX is trying to do, is a hard task. Eurex, Europe’s largest futures exchange, set up shop in Chicago this year, intending to grab American Treasury-bond contracts from the Chicago Board of Trade. It has made little progress. And the NYMEX has tried to get Brent contracts before, without success.[6] Given the importance of liquidity in exchanges, why do the IPE and the NYMEX not work together? There have been talks about cooperation before, and something might yet happen. Some say that the freewheeling NYMEX and the more serious IPE could never mix. For now, in any case, the two exchanges will compete until one has won --across the Irish Sea as well as across the Atlantic.63. According to the text, the NYMEX and IPE are __________.A. both using open outcry trading as a major trading formB. partners that benefit each other in their business activitiesC. rivals that are competing in the oil trading marketD. both taking efforts to modernize their trading practice64. The word “glitches” in Line 2, Paragraph 4 most probably means __________.A. backwardnessB. disappointmentsC. engineersD. problems65. From Paragraph 4 we can infer that __________.A. trading volume in the IPE’s new morning electronic session is fallingB. London is a better business location for energy exchanges than DublinC. Britain’s regulators are less efficient than those of IrelandD. the Dublin pit of the NYMEX will be more prosperous next year66. We can draw a conclusion from the text that __________.A. it’s very unlikely that the NYMEX and the IPE could combine their businessesB. the NYMEX will fail in Ireland as many precedents have shownC. the two energy exchanges will figure out a way to cooperate with each otherD. the market environment for both energy exchanges is getting betterKeys:63-66: C D B ASection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have read.( C )①Australians have long been known for having a relaxed and casual attitude to life. According to Dr Tanya King, senior lecturer from Victoria’s Deakin University, “It’s Australians’ egalitarianism, sense of humor and informal language that are most commonly mentioned as examples of this attitude”.②Egalitarianism roots in the way that the nation was built. In Australia’s founding era in the late 1700s, criminal settlers were often cruelly treated and robbed of their basic human rights by governors. The criminal class, who were mostly working-class Brits and Irish, was unable to seek civic positions that were reserved for immigrants who were not the criminal, with the latter arguing that if criminals gained equal rights it would be ‘rewarding criminality’. Bec ause of this, an egalitarian spirit was worn as a symbol of honor by many criminal settlers. They may not have had power, education or wealth, but they had a shared belief in equality.③The informal way Australians use language is also believed to root in criminal times. Philologist Sidney Baker once wrote that ‘no other class would have a better talent for creating new terms to fit in with their new conditions in life’. Cockney rhyming slang brought over by the British working class was abbreviated even further –so ‘have a Captains Cook’ (have a look), became ‘ava captains’. This same practice was used to economize ordinary clauses. Words like ‘good day’ became ‘g’day’, and barbecue was ‘barbie’.④The tough conditions of settler times also played a part in Australians’ dry, self-criticizing and sarcastic(讽刺的)sense of humor. While in many countries it’s considered poor taste to find humor in difficult circumstances, Australians tend to look at the lighter side. On one road trip, as I hit the state line and entered Victoria, I drove past some blackened trees, the leftovers of a recent bushfire. A road sign warning drivers about wildlife was half-melted and bent, but the shape of a hopping kangaroo was still distinct. Behind the figure, someone had drawn flames making it look asthough the animal’s tail was on fire. I couldn’t help but laugh – it was a brilliant reminder of the country’s ‘nothing upsets us’ and anti-authoritarian attitude.⑤And one thing you can’t help but notice when driving around Australia is the country’s plentiful amounts of space. This, along with considerable leisure time plus favorable climate, all contribute to Australians’ relaxed attitude.63. The underlined word “egalitarianism” is closest to __________ in meaning.A. criminalityB. crueltyC. equalityernmentalism64. Which of the following is a feature of the way Australians use language?A. They use more slangs than other people.B. They give new meanings to existent words.C. They favour shortened forms of expressions.D. They coin terms in memory of criminal times.65. What can be inferred from paragraph 4?A. Kangaroos’ living condition s are getting tougher.B. Forest fires threaten Australian s’ life to a great extent.C. Potential danger is here and there on the roads in Victoria.D. Australians’ jokes may not be as careless as they seem on the surface.66. The passage mainly talks about __________.A. how the late 1700s impacted AustraliaB. why Australians enjoy casual life so muchC. what cont ributes to Australians’ relaxed lifestyleD. how Australians present their attitude towards lifeKeys: 63-66 CCABSection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. Choose the one that fits best according to the information given in the passage you have just read.(C)Dental health: Brush with confidenceChildren should be taught to brush their teeth regularly. But the suspicion remains among some people, dentists included, that even so, certain children are doomed to develop dental cavities. The hypothesis behind this fear is that some combinations of genes may give rise to the sorts of oral bacteria which are responsible for cavities. If true, that would be sad for the youngsters concerned. But a study just published in Cell Host and Microbe, by Andres Gomez and Karen Nelson of the J. Craig Venter Institute, in San Diego, suggests it isn’t true.The mouth is home to many species of microbes. Most are good. Some, though, are well known to secrete acidic waste products when fed sugar. This acidity weakens teeth, causing them to decay.To try to fin d out whether a child’s genes play any role in encouraging such acid-secreting bugs, Dr Gomez and Dr Nelson set up an experiment with twins.Their“volunteers”were 280 pairs of fraternal twins and 205 pairs o f identical twins, all aged between five and 11, who had not taken antibiotics during the previous six months. The children were asked to stop brushing their teeth the evening and the morning before the crucial moment of data collection. This was when the researchers swabbed the children’s gingival sulci(the clefts between teeth and gums, in which bacteria collect)to find out what was there. The children also had their teeth scored by dentists as belonging to one of three categories: having no signs of current or previous dental cavities: having signs of current or previous cavities affecting the enamel(a tooth’s hard, outer layer); or having signs of cavities that penetrated the enamel and affected the underlying dentine as well.Dr Gomez and Dr Nelson found that, though identical twins shared many groups of bacteria which were not shared by fraternal twins, none of these was a type responsible for cavities. Moreover, similarities in bacterial flora were greatest among five-to seven-year-olds, weaker among seven- to nine-year-olds and weakest among nine-to 11-year-olds. This suggests that any role genes do play in regulating the mouth’s ecology fades with time.Far from supporting the idea that some children are fated to suffer from cavities no matter how well they brush their teeth, these results make it clear that the power to control the growth of the relevant bacteria is very much within reach of children and their parents. Brushing, however, may not be the onlyapproach. Avoiding sugary foods is obviously de rigueur. It seems likely, though, that which other foods a child eats may help shape his oral ecosystem, too. This is an area of ongoing research. But, as in the intestines(肠道), so in the mouth, scientific medicine is at last coming to grips with the fact that the mixture of microbes present is both important and capable of manipulation, to the benefit of the host.63. What doe s“hypothesis”refer to in paragraph 1?A. Children’s failure to brush their teeth properly leads to tooth decay.B. Some children are programmed to develop tooth decay.C. Youngsters are suspicious of the effectiveness of tooth-brushing.D. Some genes are more likely to lead to dental cavities.64. Dr Gomez and Dr Nelson conducted an experiment to find out .A. whether genes have anything to do with dental decayB. which group of twins are more likely to have decayed teethC. what kinds of foods tend to give rise to tooth decayD. why the ecosystem of the intestines is similar to that of the mouth65. Which of the following statements is UNTRUE according to the passage?A. Scientists are not yet sure how ecosystem of the mouth is formed.B. The role genes play in controlling ecosystem of the mouth weakens with the time.C. The children are classified into three groups according to the degrees of dental cavities.D. Identical twins are not as genetically close to each other as fraternal twins.66. What can we learn from the last paragraph?A. The existence of multiple microbes benefits children’s oral ecosystem.B. What a child eats enhances the healthfulness of a child’s oral ecosystem.C. Cutting down on sugar intake is the most likely way to prevent tooth decay.D. Parents are in no position to help their children maintain healthy oral ecosystem.Keys: 60-62 DCBSection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have read.( C )Many United States companies have made the search for legal protection from import competition into a major line of work. Since 1980, the United States International Trade Commission (ITC) has received about 280 complaints alleging damage from imports that benefit from subsidies(补贴) by foreign governments. Another 340 charge that foreign companies “dumped”their products in the United States at “less than fair value.”Even when no unfair practices are claimed, the simple claim that an industry has been injured by imports is sufficient grounds to seek relief(救济).Contrary to the general impression, this request for import relief has hurt more companies than it has helped. As corporations begin to function globally, they develop a complicated web of marketing, production, and research relationships. The complexity of these relationships makes it unlikely that a system of import relief laws will meet the strategic needs of all the units under the same parent company. Internationalization increases the danger that foreign companies will use import relief laws against the very companies the laws were designed to protect. Suppose a United States-owned company establishes an overseas plant to manufacture a product while its competitor makes the same product in the United States. If the competitor can prove injury from the imports—and that the United States company received a subsidy from a foreign government to build its plant abroad—the United States company’s products will be uncompetitive in the United States, since they would be subject to duties.Perhaps the most shameful case occurred when the ITC investigated allegations(控诉) that Canadian companies were injuring the United States salt industry by dumping rock salt, used to deice roads. The bizarre aspect of the complaint was that a foreign conglomerate(联合企业)with United States operations was crying for help against a United States company with foreign operations. The “United States”company claiming injury was a unit of a Dutch conglomerate, while the “Canadian”companies included a unit of a Chicago firm that was the second-largest domestic producer of rock salt.63.The passage is chiefly concerned with_______________.A. arguing against the increased internationalization of US corporations.B. warning that the application of laws affecting trade frequently has unintended consequences.C. recommending a uniform method for handling claims of unfair trade practices.D. advocating the use of trade restrictions for "dumped" products but not for other imports.64.What can be inferred about the minimal basis for a complaint to the ITC ____________.A. A foreign competitor is selling products in the US at less than fair market value.B. A foreign competitor has greatly increased the volume of products shipped to the US.C. The company requesting import relief has been banned from exporting products.D. The company requesting import relief has been injured by the sale of imports in the US.65.What is the function of the last paragraph?A. It summarizes the discussion and suggests additional areas for research.B. It makes a recommendation based on the evidence presented earlier.C. It uses a specific case to illustrate a problem in the previous paragraph.D. It introduces an additional area of concern not mentioned earlier.66.Which of the following is most likely to be true of US trade laws?A. They will eliminate the practice of "dumping" products in the US.B. Those applied to international companies will help to gain more profits.C. They will affect US trade with Canada more negatively than trade with other nations.D. Those helping one unit within a parent company won’t necessarily help other units. Keys:63-66 BDCDSection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(C)More than five million different kinds of organisms(生物体) live on the Earth. For thousands of years, humans have searched for ways to organize this diversity(多样性). In the eighteenthcentury, a Swedish professor, physician, and naturalist named Carolus Linnaeus developed the system of naming and classifying organisms that we use today.Linnaeus contributed to the modern classification of organisms in two ways. He first developed a convention for naming life forms.Before Linnaeus came up with a standardized system of naming, there were often many names for a single species, and these names tended to be long and confusing. Linnaeus decided that all species names should be in Latin and should have two parts, one indicating the genus(plural: genera), a group that includes similar species and one indicating the specific name of the species. When written alone, the specific name is meaningless since many different species in different genera have the same specific name. The specific name familiaris, for example, is commonly used to describe species. Therefore, when used by itself, it would not describe any one organism. When the genus is also given, however, as in Canis familiaris, we know that the name refers to a specific organism: the domestic dog.Linnaeus was also the originator of modern taxonomy, a system of classifying nature based on hierarchical(分层的) groupings. Linnaeus first grouped life forms into three broad groups, called kingdoms. These kingdoms were animals, plants, and minerals. He divided each of these kingdoms into classes, classes into orders, orders into genera (genus is singular) and then genera into species, grouping organisms according to shared physical characteristics.Although modern taxonomists still use the hierarchical structure of Linnaeus’s classification system as well as his method of grouping organisms according to observable similarities, they have added hierarchical levels and significantly changed Linnaeus’s original groupin gs. The broadest level of life is now a domain. All living things fit into only three domains. Within each of these domains there are kingdoms. Each kingdom contains phyla (singular is phylum), followed by class, order, family, genus, and species.In addition to the Linnaean kingdoms of plants and animals, biologists recognize prokaryotes, protists, and fungi as separate kingdoms. The prokaryotes are the oldest and most abundant group of organisms. They are also the smallest cellular organisms. Common bacteria, which have been known to survive in many environments that support no other form of life, fall into this category. The protist kingdom is made up of a variety of single-celled or simple multicellular organisms. Protists do not have much in common. They are, essentially, those organisms which do not fit into any other kingdom. Fungi compose a third kingdom. Like plants, the cells of fungi have cell walls,giving them a tube-like structure. However, fungi do not produce their own carbon as plants do. Rather, they acquire nutrients by absorbing and digesting carbon produced by other organisms. Yeasts and mushrooms are examples of fungi.63. The writer gives the scientific name of the domestic dog in paragraph 3 in order to__________.A. demonstrate Linna eus’s method of classificationB. introduce the need for a better system of naming organismsC. criticize the complexity of Linnaeus’s naming systemD. illustrate the necessity of including two parts when naming organism64. Which of the following can be learned from the passage?A. The hierarchical structure of Linnaeus’s system for classifying is no longer in use.B. Linnaeus’s original system of classification consisted of 3 domains.C. Linnaeus’s original system of classification is used today with lit tle modifications.D. Modern taxonomists have added categories and regrouped organisms.65. Which of the following is TRUE about protists?A. They do not share the characteristics of any of the other four kingdoms.B. They are grouped together based on similar characteristics.C. They are limited to single-cell organisms.D. They acquire nutrients by eating other organisms.66. Which of the following might be the best title of the passage?A. The Father of Modern TaxonomyB. Classifying OrganismsC. Development in Life FormsD. Linnaeus’s Classification SystemKEYS: 63-66 DDABSection BDirections:Read the following passages. Each passage is followed by several questions or Unfinished statements. For each of them there are four choices marked A. B. C and D. Choose theone that fits best according to the information given in the passage you have just read.(C)One of the main challenges facing many countries is how to maintain their identity in the face of globalization and the growing multi-language trend. "One of the main reasons for economic failure in many African countries is the fact that, with a few important exceptions, mother-tongue education is not practiced in any of the independent African states." said Nellie Alexander, Director of the Project for the Study of Alternative education in South Africa at the University of Cape Town.In response to the spread of English and the increased multi-language trends arising from immigration, many countries have introduced language laws in the laws in the last decade. In some, the use of languages other than the national language is banned in public spaces such as advertising posters. One of the first such legal provisions was the 1994 "Toubon Law" in France, but the idea has been copied in man y countries since then. Such efforts to govern language use are often dismissed as futile by language experts, who are well aware of the difficultly in controlling fashions in speech and know from research that language switching among bilinguals is a natural process.It is especially difficult for native speakers of English to understand the desire to maintain the “purity” of a language by law. Since the time of Shakespeare, English has continually absorbed foreign words into its own language. English is one of the most mixed and rapidly changing languages in the world, but there has not been a barrier to acquiring prestige and power. Another reason for the failure of many native English speakers to understand the role of state regulation is that it has never been the Anglo-Saxon way of doing things. English has never had a state-controlled authority for the language, similar, for example, to the Academic Francaise in France.The need to protect national languages is, for most western Europeans, a recent phenomenon—especially the need to ensure that English does not unnecessary take over too many fields. Public communication, education and new modes of communication promoted by technology, may be key fields lo defend.63. Neville Alexander believes that?A. mother-tongue education is not practiced in all African countriesB. globalization has resulted in the economic failure of AfricaC. globalization has led to the rise of multi-language trendsD. lack of mother-tongue education can lead to economic failure64. The underlined word “futile” (i n paragraph 2) most probably means “”.A. workableB. practicalC. uselessD. unnecessary65. Why do many English-speaking countries not support the language protection effortsdescribed in the passage?A. They think language protection laws are ineffective.B. They want their language to spread to other countries.C. They have a long history of taking words from other languages.D. It reduces a language's ability to acquire international importance66. What can we infer from the last paragraph?A. English has taken over fields like public communication and educationB. Many sheets of national culture are threatened by the spread of English.C. Most language experts believe it is important to promote a national language.D. Europeans have long realized the need to protect their national languages.KEYS: 63-66 D C C BSection BDirections:Read the following passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(C)With the coming of big data age, data science is supposed to be starved for, of which the adaption can point a profound change in corporate competitiveness. Companies, both born in the digital era and traditional world are showing off their skills in data science. Therefore, it seems to have been creating a great demand for the experts of this type.Mr Carlos Guestrin, machine learning professor from University of Washington argues that all software applications will need in built intelligence within five years, making data scientists-people trained to analyze large bodies of information-key workers in this emerging “cognitive” technology economy. There are already critical applications that depend on machine learning, a subfield of data science, led by recommendation programs, fraud detection systems, forecasting tools and applications for predicting customer behavior.Many companies that are born digital-particularly internet companies that have a great number of real-time customer interactions to handle-are all-in when it comes to data science. Pinterest, for instance, maintains more than 100 machine learning models that could be applied to different classes of problems, and it constantly fields requests from managers eager to use this resource to deal with their business problem.The factors weighing on many traditional companies will be the high cost of mounting a serious machine-learning operation. Netflix is estimated to spend $ 150m a year on a single application and the total bill is probably four times that once all its uses of the technology are taken into account.Another problem for many non-technology companies is talent. Of the computer science experts who use Kaggle, only about 1,000 have deep learning skills, compared to 100,000 who can apply other machine learning techniques, says Mr Goldbloom. He adds that even some big companies of this type are often reluctant to expand their pay scales to hire the top talent in this field.The biggest barrier to adapting to the coming era of “smart” applications, however, is likely to be cultural. Some companies, such as General Electric, have been building their own Silicon Valley presence to attract and develop the digital skills they will need. Despite the obstacles, some may master this difficult transition. But companies that were built, from the beginning, with data science at their center, are likely to represent serious competition.63. Which one is obstacle for many traditional companies to popularize learning operation?A. Technological problemB. Expert crisisC. High costD. Customer interactions64. What can not be interred from the passage about the machine learning?A.Machine learning operations are costly in Netflix.B.Machine learning plays an important role in existent applications.。

If true, that would be sad for the youngsters concerned. But a study just published in Cell Host and Microbe, by Andres Gomez and Karen Nelson of the J. Craig Venter Institute, in San Diego, suggests it isn’t true.The mouth is home to many species of microbes. Most are good. Some, though, are well known to secrete acidic waste products when fed sugar. This acidity weakens teeth, causing them to decay.To try to fin d out whether a child’s genes play any role in encouraging such acid-secreting bugs, Dr Gomez and Dr Nelson set up an experiment with twins.Their“volunteers”were 280 pairs of fraternal twins and 205 pairs o f identical twins, all aged between five and 11, who had not taken antibiotics during the previous six months. The children were asked to stop brushing their teeth the evening and the morning before the crucial moment of data collection. This was when the researchers swabbed the children’s gingival sulci(the clefts between teeth and gums, in which bacteria collect)to find out what was there. The children also had their teeth scored by dentists as belonging to one of three categories: having no signs of current or previous dental cavities: having signs of current or previous cavities affecting the enamel(a tooth’s hard, outer layer); or having signs of cavities that penetrated the enamel and affected the underlying dentine as well.Dr Gomez and Dr Nelson found that, though identical twins shared many groups of bacteria which were not shared by fraternal twins, none of these was a type responsible for cavities. Moreover, similarities in bacterial flora were greatest among five-to seven-year-olds, weaker among seven- to nine-year-olds and weakest among nine-to 11-year-olds. This suggests that any role genes do play in regulating the mouth’s ecology fades with time.Far from supporting the idea that some children are fated to suffer from cavities no matter how well they brush their teeth, these results make it clear that the power to control the growth of the relevant bacteria is very much within reach of children and their parents. Brushing, however, may not be the onlyapproach. Avoiding sugary foods is obviously de rigueur. It seems likely, though, that which other foods a child eats may help shape his oral ecosystem, too. This is an area of ongoing research. But, as in the intestines(肠道), so in the mouth, scientific medicine is at last coming to grips with the fact that the mixture of microbes present is both important and capable of manipulation, to the benefit of the host.63. What doe s“hypothesis”refer to in paragraph 1?A. Children’s failure to brush their teeth properly leads to tooth decay.B. Some children are programmed to develop tooth decay.C. Youngsters are suspicious of the effectiveness of tooth-brushing.D. Some genes are more likely to lead to dental cavities.64. Dr Gomez and Dr Nelson conducted an experiment to find out .A. whether genes have anything to do with dental decayB. which group of twins are more likely to have decayed teethC. what kinds of foods tend to give rise to tooth decayD. why the ecosystem of the intestines is similar to that of the mouth65. Which of the following statements is UNTRUE according to the passage?A. Scientists are not yet sure how ecosystem of the mouth is formed.B. The role genes play in controlling ecosystem of the mouth weakens with the time.C. The children are classified into three groups according to the degrees of dental cavities.D. Identical twins are not as genetically close to each other as fraternal twins.66. What can we learn from the last paragraph?A. The existence of multiple microbes benefits children’s oral ecosystem.B. What a child eats enhances the healthfulness of a child’s oral ecosystem.C. Cutting down on sugar intake is the most likely way to prevent tooth decay.D. Parents are in no position to help their children maintain healthy oral ecosystem.Keys: 60-62 DCBSection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have read.( C )Many United States companies have made the search for legal protection from import competition into a major line of work. Since 1980, the United States International Trade Commission (ITC) has received about 280 complaints alleging damage from imports that benefit from subsidies(补贴) by foreign governments. Another 340 charge that foreign companies “dumped”their products in the United States at “less than fair value.”Even when no unfair practices are claimed, the simple claim that an industry has been injured by imports is sufficient grounds to seek relief(救济).Contrary to the general impression, this request for import relief has hurt more companies than it has helped. As corporations begin to function globally, they develop a complicated web of marketing, production, and research relationships. The complexity of these relationships makes it unlikely that a system of import relief laws will meet the strategic needs of all the units under the same parent company. Internationalization increases the danger that foreign companies will use import relief laws against the very companies the laws were designed to protect. Suppose a United States-owned company establishes an overseas plant to manufacture a product while its competitor makes the same product in the United States. If the competitor can prove injury from the imports—and that the United States company received a subsidy from a foreign government to build its plant abroad—the United States company’s products will be uncompetitive in the United States, since they would be subject to duties.Perhaps the most shameful case occurred when the ITC investigated allegations(控诉) that Canadian companies were injuring the United States salt industry by dumping rock salt, used to deice roads. The bizarre aspect of the complaint was that a foreign conglomerate(联合企业)with United States operations was crying for help against a United States company with foreign operations. The “United States”company claiming injury was a unit of a Dutch conglomerate, while the “Canadian”companies included a unit of a Chicago firm that was the second-largest domestic producer of rock salt.63.The passage is chiefly concerned with_______________.A. arguing against the increased internationalization of US corporations.B. warning that the application of laws affecting trade frequently has unintended consequences.C. recommending a uniform method for handling claims of unfair trade practices.D. advocating the use of trade restrictions for "dumped" products but not for other imports.64.What can be inferred about the minimal basis for a complaint to the ITC ____________.A. A foreign competitor is selling products in the US at less than fair market value.B. A foreign competitor has greatly increased the volume of products shipped to the US.C. The company requesting import relief has been banned from exporting products.D. The company requesting import relief has been injured by the sale of imports in the US.65.What is the function of the last paragraph?A. It summarizes the discussion and suggests additional areas for research.B. It makes a recommendation based on the evidence presented earlier.C. It uses a specific case to illustrate a problem in the previous paragraph.D. It introduces an additional area of concern not mentioned earlier.66.Which of the following is most likely to be true of US trade laws?A. They will eliminate the practice of "dumping" products in the US.B. Those applied to international companies will help to gain more profits.C. They will affect US trade with Canada more negatively than trade with other nations.D. Those helping one unit within a parent company won’t necessarily help other units.

Choose the one that fits best according to the information given in the passage you have just read.(C)More than five million different kinds of organisms(生物体) live on the Earth. For thousands of years, humans have searched for ways to organize this diversity(多样性). In the eighteenthcentury, a Swedish professor, physician, and naturalist named Carolus Linnaeus developed the system of naming and classifying organisms that we use today.Linnaeus contributed to the modern classification of organisms in two ways. He first developed a convention for naming life forms.Before Linnaeus came up with a standardized system of naming, there were often many names for a single species, and these names tended to be long and confusing. Linnaeus decided that all species names should be in Latin and should have two parts, one indicating the genus(plural: genera), a group that includes similar species and one indicating the specific name of the species. When written alone, the specific name is meaningless since many different species in different genera have the same specific name. The specific name familiaris, for example, is commonly used to describe species. Therefore, when used by itself, it would not describe any one organism. When the genus is also given, however, as in Canis familiaris, we know that the name refers to a specific organism: the domestic dog.Linnaeus was also the originator of modern taxonomy, a system of classifying nature based on hierarchical(分层的) groupings. Linnaeus first grouped life forms into three broad groups, called kingdoms. These kingdoms were animals, plants, and minerals. He divided each of these kingdoms into classes, classes into orders, orders into genera (genus is singular) and then genera into species, grouping organisms according to shared physical characteristics.Although modern taxonomists still use the hierarchical structure of Linnaeus’s classification system as well as his method of grouping organisms according to observable similarities, they have added hierarchical levels and significantly changed Linnaeus’s original groupin gs. The broadest level of life is now a domain. All living things fit into only three domains. Within each of these domains there are kingdoms. Each kingdom contains phyla (singular is phylum), followed by class, order, family, genus, and species.In addition to the Linnaean kingdoms of plants and animals, biologists recognize prokaryotes, protists, and fungi as separate kingdoms. The prokaryotes are the oldest and most abundant group of organisms. They are also the smallest cellular organisms. Common bacteria, which have been known to survive in many environments that support no other form of life, fall into this category. The protist kingdom is made up of a variety of single-celled or simple multicellular organisms. Protists do not have much in common. They are, essentially, those organisms which do not fit into any other kingdom. Fungi compose a third kingdom. Like plants, the cells of fungi have cell walls,giving them a tube-like structure. However, fungi do not produce their own carbon as plants do. Rather, they acquire nutrients by absorbing and digesting carbon produced by other organisms. Yeasts and mushrooms are examples of fungi.63. The writer gives the scientific name of the domestic dog in paragraph 3 in order to__________.A. demonstrate Linna eus’s method of classificationB. introduce the need for a better system of naming organismsC. criticize the complexity of Linnaeus’s naming systemD. illustrate the necessity of including two parts when naming organism64. Which of the following can be learned from the passage?A. The hierarchical structure of Linnaeus’s system for classifying is no longer in use.B. Linnaeus’s original system of classification consisted of 3 domains.C. Linnaeus’s original system of classification is used today with lit tle modifications.D. Modern taxonomists have added categories and regrouped organisms.65. Which of the following is TRUE about protists?A. They do not share the characteristics of any of the other four kingdoms.B. They are grouped together based on similar characteristics.C. They are limited to single-cell organisms.D. They acquire nutrients by eating other organisms.66.

Choose theone that fits best according to the information given in the passage you have just read.(C)One of the main challenges facing many countries is how to maintain their identity in the face of globalization and the growing multi-language trend. "One of the main reasons for economic failure in many African countries is the fact that, with a few important exceptions, mother-tongue education is not practiced in any of the independent African states." said Nellie Alexander, Director of the Project for the Study of Alternative education in South Africa at the University of Cape Town.In response to the spread of English and the increased multi-language trends arising from immigration, many countries have introduced language laws in the laws in the last decade. In some, the use of languages other than the national language is banned in public spaces such as advertising posters. One of the first such legal provisions was the 1994 "Toubon Law" in France, but the idea has been copied in man y countries since then. Such efforts to govern language use are often dismissed as futile by language experts, who are well aware of the difficultly in controlling fashions in speech and know from research that language switching among bilinguals is a natural process.It is especially difficult for native speakers of English to understand the desire to maintain the “purity” of a language by law. Since the time of Shakespeare, English has continually absorbed foreign words into its own language. English is one of the most mixed and rapidly changing languages in the world, but there has not been a barrier to acquiring prestige and power. Another reason for the failure of many native English speakers to understand the role of state regulation is that it has never been the Anglo-Saxon way of doing things. English has never had a state-controlled authority for the language, similar, for example, to the Academic Francaise in France.The need to protect national languages is, for most western Europeans, a recent phenomenon—especially the need to ensure that English does not unnecessary take over too many fields. Public communication, education and new modes of communication promoted by technology, may be key fields lo defend.63. Neville Alexander believes that?A. mother-tongue education is not practiced in all African countriesB. globalization has resulted in the economic failure of AfricaC. globalization has led to the rise of multi-language trendsD. lack of mother-tongue education can lead to economic failure64. The underlined word “futile” (i n paragraph 2) most probably means “”.A. workableB. practicalC. uselessD. unnecessary65. Why do many English-speaking countries not support the language protection effortsdescribed in the passage?A. They think language protection laws are ineffective.B. They want their language to spread to other countries.C. They have a long history of taking words from other languages.D. It reduces a language's ability to acquire international importance66. What can we infer from the last paragraph?A. English has taken over fields like public communication and educationB. Many sheets of national culture are threatened by the spread of English.C. Most language experts believe it is important to promote a national language.D. Europeans have long realized the need to protect their national languages.KEYS: 63-66 D C C BSection BDirections:Read the following passages.

Choose the one that fits best according to the information given in the passage you have just read.(C)With the coming of big data age, data science is supposed to be starved for, of which the adaption can point a profound change in corporate competitiveness. Companies, both born in the digital era and traditional world are showing off their skills in data science. Therefore, it seems to have been creating a great demand for the experts of this type.Mr Carlos Guestrin, machine learning professor from University of Washington argues that all software applications will need in built intelligence within five years, making data scientists-people trained to analyze large bodies of information-key workers in this emerging “cognitive” technology economy. There are already critical applications that depend on machine learning, a subfield of data science, led by recommendation programs, fraud detection systems, forecasting tools and applications for predicting customer behavior.Many companies that are born digital-particularly internet companies that have a great number of real-time customer interactions to handle-are all-in when it comes to data science. Pinterest, for instance, maintains more than 100 machine learning models that could be applied to different classes of problems, and it constantly fields requests from managers eager to use this resource to deal with their business problem.The factors weighing on many traditional companies will be the high cost of mounting a serious machine-learning operation. Netflix is estimated to spend $ 150m a year on a single application and the total bill is probably four times that once all its uses of the technology are taken into account.Another problem for many non-technology companies is talent. Of the computer science experts who use Kaggle, only about 1,000 have deep learning skills, compared to 100,000 who can apply other machine learning techniques, says Mr Goldbloom. He adds that even some big companies of this type are often reluctant to expand their pay scales to hire the top talent in this field.The biggest barrier to adapting to the coming era of “smart” applications, however, is likely to be cultural. Some companies, such as General Electric, have been building their own Silicon Valley presence to attract and develop the digital skills they will need. Despite the obstacles, some may master this difficult transition. But companies that were built, from the beginning, with data science at their center, are likely to represent serious competition.63. Which one is obstacle for many traditional companies to popularize learning operation?A. Technological problemB. Expert crisisC. High costD. Customer interactions64. What can not be interred from the passage about the machine learning?A.Machine learning operations are costly in Netflix.B.Machine learning plays an important role in existent applications.。

Each word can only be used once. Note thatThere is a tendency to think of each of the arts as a separate area of activity. Many artists, however, would prove that there has always been a warm relationship between the 41 areas of human activity. For example, in the late nineteenth century the connections between music andpainting were 42 close. zhucanqi Artists were invited to design clothes and settings for operas and ballets, but sometimes it was the musicians who were inspired by the work of 43 painters. Of the musical compositions that were considered as responses to the visual arts, perhaps the most famous is Mussorgsky’s Pictures at an Exhibition.TexyhMII9t Mussorgsky 44 the piece in 1874 after the death, at the age of 39, of the artist Victor Hartmann. Though their friendship had not been a particularly long-lasting one, Mussorgsky was shocked by Hartmann’s 45 death. The following year the critic, Vladimir Stasov, who decided to hold an exhibition of Hartmann’s work, suggested that Mussorgsky try to 46 his grief by writing something in 47 of Hartmann.TexyhMII9tThe exhibition served as Mussorgsky’s inspiration. The ten pieces that make up Pictures at an Exhibition are 48as symbols rather than representations of the paintings inthe exhibition.

These days, homeschooling in America is51 .TexyhMII9tTeaching methods at homeschooling 52 . Some parentsf o l l o w a s t r i c t t i m e t a b l e a n d T e x y h M I I9t53 a traditional school environment. Other parentsfollow an extreme form of homeschooling in which they do not give grades or tests and allow their children to study wherever they want. More parents, however, follow the middle 54 to provide a balance between freedom anddiscipline.TexyhMII9tWhy do parents choose homeschooling? Some believe that children in public schools experience too much “peer pressure”, or social pressure from friends. They say it mayh a v e a T e x y h M I I9t55 effect on the child’s studies. Other parents are dissatisfied with the quality of education in the public school. About half the parents who teach at home are 56 motivated and use lessons by mail or Internet from church schools. Whatever the 57 may be, it is evident that more and more children are being taken out of normal schoolsevery year. 58 , many questions have emerged, encouraging the debate over home schooling against publicschooling.TexyhMII9tWhat then is the future of education? Although children often learn well at home, weak regulations in most states mean that officials rarely challenge or 59 parents who say they are home-schooling. As the 60 continues, so do the questions about what home schoolers are studying at home. How can parents ensure that their children are prepared academically for college? How are home schoolers 61 to make sure they are getting the same educational standards that school students must have? Recent studies in the United States have shown that homeschooled children tend to be slightly better in subjects like English and art, but theya r e ob v i o u s l y l e s s T e x y h M I I9t62 math and science.

They found that wild elephants are healthier, live longer and reproduce more than those elephants inzoos.TexyhMII9tWhen it comes to living in a zoo, “many species do well but elephants don’t,” said Georgia Mason, one of the researchers of the study. Many animals live longer in zoos than they do in the wild. This isn’t surprising when you consider that zoo animals are not threatened by predators(掠食者>, always have plenty to eat, P.F. Productions and have professionals on hand to care for them.TexyhMII9t When it comes to elephants, however, the situation is different. The world’s largest land animals live muchlonger in the wild than they do in zoos.TexyhMII9tFemale African elephants born in zoos live on average for 17 years, while those in the wild make it to 56. “So far,”says Mason, “We’ve got 300 African elephants in zoos in Europe, and not one’s yet reached 50.”TexyhMII9tAsian elephants are the more endangered of the two elephant species. They live for about 19 years in captivity (圈养> compared to 42 years in the wild. A few wild Asian elephants have even made it into their 70s. In Kenya, 30 to50 percent of wild elephants reach 50 years ofage.TexyhMII9tFatness and stress are likely causes for the giant land animals’ early death in captivity, Mason said.TexyhMII9t The researchers say that zoos do not offer enough spacefor animals that can travel as far as 48 kilometers a day. Too little exercise and too much food means captiveelephants put on extra weight. The weight gain can lead to heart disease and other health problems.TexyhMII9tBeing “caged” is bad for health, not only for elephants, but also for humans. Be careful not to become a “caged elephant”!TexyhMII9t66. Many animals live longer in zoos owing to the following reasons EXCEPT that ________. A. they are far awayfrom the danger of being eaten.TexyhMII9tB. they can be in a better mood there.C. they needn’t worry about their food at all.D. they are taken good care of.67. Which of the following may probably result in the early death of elephants in zoos?TexyhMII9tA. Stress and lack of delicious food.B. Loneliness and little space for activities.TexyhMII9tC. Lack of delicious food and enough exercise.D. Being stressed and over weight.TexyhMII9t68. What can be concluded from the passage?A. Zoos are not suitable for animals to live in.B. None of the animals live well in zoos due to lack of exercise.TexyhMII9tC. Compared with the elephants in zoos, wild elephants are healthier.TexyhMII9tD. Asian elephants can live longer than African elephants in zoos.TexyhMII9t69. What is the passage mainly about?A. The living conditions of animals in the world are worsening.TexyhMII9tB. Elephants can live a longer time in the wild than in zoos.TexyhMII9tC. All of us should take actions to protect wild elephants.TexyhMII9tD.

Psychologists view the subject either as a matter of failure or a joke. Now the biologists have moved into this field, and some of them have found that there are real differences between the brains of men and women. But being different, they point out hurriedly, is not the same as being better or worse.TexyhMII9tThere is, however, a definite structural variation between the male and female brain. The difference is in a part of the brain that is used in the most complex intellectual processes—the link between the two halves of the brain.TexyhMII9tThe two halves are linked by a trunkline (主干线> of between 200 and 300 million nerves, the corpus callosum. Scientists have found quite recently that the corpuscallosum in women is always larger and probably richer in nerve fibres (纤维> than it is in men. This is the first time that a structural difference has been found between the brains of women and men and it must have some significance. The question is “What?”, and if this difference exists, are there others? Research shows that present-day womenthink differently and behave differently from men. Are some of these differences biological and inborn, a result of evolution? We tend to think that is the influence of society that produces these differences. But could we bewrong?TexyhMII9tResearch showed that these two halves of the brain had different functions, and that the corpus callosum enabled them to work together. The better the connections, the more harmoniously the two halves work. Usually, women have the better connections.TexyhMII9tBut it isn’t all that easy to explain the actual differences between the skills of men and women on this basis. In schools throughout the world girls tend to be better than boys at “language subjects” and boys better at math. If these differences correspond (相符合> with the differences in the trunkline, there is an unchangeable distinction between the sexes.TexyhMII9tWe shan’t know for a while, partly because we don’t know of the exact relationship between abilities in school subjects and the functioning of the two halves of the brain. And we cannot understand how the two halves interact through the corpus callosum. But one thing is certain: nothing in our world is still—even scientific thought.TexyhMII9t74. Which of the following statements is TRUE?A. Biologists are doing research where psychologists have given up.TexyhMII9tB. Brain differences point to advantage of one sex over the other.TexyhMII9tC. The structural difference in the brain between the sexes has long been known.TexyhMII9tD. The brain difference is the only difference between the sexes.TexyhMII9t75. According to the passage, it is commonly believed thatbrain differences are caused by ________factors.TexyhMII9tA. biologicalB. psychologicalC. physicalD. socialTexyhMII9t76. The expression of “these differences” refers to those in ________.TexyhMII9tA. skills of men and womenB. school subjectsC. the brain structure of men and womenD. learning habitsTexyhMII9t77. What is the main purpose of the passage?A. To discuss the various factors that cause brain differences.TexyhMII9tB. To explain the link between sex and brainstructure.TexyhMII9tC. To suggest new areas in brain research.D. To indicate the many differences between thesexes.TexyhMII9tSection CDirections: Read the following passage and then answer the questions or complete the statements in the fewest possible words.TexyhMII9tYou are what you eat and fats are a main food forAsia’s fast-food generation. Dr. Chwang, director of the Department of Food Nutrition, says children are consuming more meat and soft drinks. That is a thorough departure from the traditional diet of vegetables and rice and little meat. “They like big pieces of fried meat with a soft drink. So although they may eat the same volume of food, their calorie intake (卡路里摄入量> has increased. Now about 40 to 45percent of their calories come from fat,” saysChwang.TexyhMII9tAlthough on the whole Asians tend towards thinness, Asians’ hospitality<好客)is the first and foremost reason for the fatness of today’s generation, according to Chwang. “Asian people love food,” she says. “Eating and drinking are important social and family functions.” In the past, however, big meals were only hosted on special occasions as people were more careful with money. In today’s climate of wealth and remarkable consumption, 10-course meals are no longer reserved for significant occasions.TexyhMII9t Needless to say, that children are being spoilt by their parents is another cause of children’s overweight. More than anyone else, children are on the receiving end of their parents’ improved circumstances. “In the past, people had four or more children —now, they have one or two, so they tend to spoil them,” says Chwang. “The easiest way is to give them ‘quality food’. Parents think feeding them well is showing their love. They feel bad when their children look thin.”TexyhMII9tWhen describing the physical condition of most overweight Asian children, Chwang says: “There is a clear relationship between fatness and indoor play children spend too much time on. Children get fat because they don’t move, and eventually, they don’t want to move because they’re fat. Thanks to technology, a growing army of children prefer video games to old outdoor sports. “What do children do when watching TV or sitting in front of the computer playing video games? They eat chocolate and drink Coke,” P.F. Productions says Chwang.TexyhMII9t(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS.>TexyhMII9t78.
