These “little camels”of the Andes were the only burden bearers the Incas had in the four hundred years when they were extending their empire from Peru to Chile and northward to Quito. These animals could live at altitudes of over two and one-half miles above sea level where in the later days the horses and mules of the conquerors would die of mountain sickness.Over this road, if a llama path can be called a road, a single explorer or trader went now and again in the days of the Spanish conquerors . But the traveled route across the continent was farther north, across form Peru to Upper Peru (now Bolivia),through western Paraguay, and then down to Buenos Aires. The southern Andes practically shut the door between Chile and Argentina.46. The Uspallata Pass isA.so steep and narrow that no man has ever conquered.B.one of many famous spots of the Andes that were conquered by man .C.famous because one can command a fine view of Chile and Argentina.D. the most well-known path of the Andes because of its steepness conquered by man .47.The “little camels”meansA.camels with small humps.B.beasts of buren like small camelsC.small animals used as burden bearers in Peru, Chile and Argentina since four hundred yearsago.D.the only animals the Incas had.48.The passage states that these “little camels”couldA.travel long distances without water.B. travel long distances without rest.C. live at high altitudes.D.carry extremely heavy loads.49.The word “their”in line 4 refers toA.Indians.B.white men.C.llamas.D.burden bearers.50.the writer of this passage probably goes on to tell howmunication has been improved beween Chile and Argentina.B.even before the Incas there was a trail across the pass.C.the Andes still prevent travel between Chile and Argentina.D. Argentina for a long time opposed easy travel to Chile.BBefore World War II, our interest in the Far East was casual and sporadic. To be sure, Commodore Perry had opened Japan in 1853, and after the turn of the century we tried to keep the door open in China by diplomatic efforts. Our cultural and economic relations were more important than our political activities. We introduced Christianity, Concord grapes, and cash registers to the area. In turn ,we decorated our American homes with Japanses prints and Chinese jade, we wore Far Eastern silk, and we drank Formosa tea.Beseball because the Japanese national game and American universities had school named after them in China. But the Far East really was far ; and it was different. Its languages, spoken and written, were completely unfamiliar. Its religions were concerned with different gods, different forms of worship, and different explanations of the purpose of life. Its organizations-government, school, and family-rested on a different basis of authority. Even its people had different characteristics and capabilities.Nor did we make any great effort to learn about the Far East. The attention of our education system and most of our scholars was concentrated upon our immediate society and its origin. This enterprise carried used across the Atlantic, and we studied European history and culture. We pursued our cultural ancestry back to the Greek, the Romans,and the Hebrews. But the usual college graduate knew more about the moon than he did about Korea,more about the early Romans than he did about contemporary China. –Willard Thop—51. Before World War IIA.political activities were far more important than cultural activities.B.American universities had schools nameds after them in China.C.the Far East was an important area for growing grapes.D.Japan introduced cash registers into China.52.The main idea of these paragraphs is thatA.there was not a close relationship between the United States and the Far East beforeWorld War II.B.Since Commondore Perry opened Japan in 1853 many western ideas have beenintroduced into Japan.C.though there had been some cultural relations, the Far was still very different from theWest.D.Americans were not interested in the Far East.53.The lack of interest in the Far East was a result ofA.the attitude toward the Far East that it had little true culture worth studying.B.a recongnition that Far Eastern culture was different.C.the priority given to one’s own society and its origins.D.the little contact because of distance.54.To “keep the door open in China”means toA.protect vested interests of the colonial powers.B.maintain diplomatic exchanges of personnel.C.continue commercial and cultural relationships.D.prevent efforts to keep us out of China.55.Far eastern religions were characterized as—A.interested in Christianity.B.unlike those in west .C.related to their basis of authority.D.casual and unrelated to language..CThe market investigation is indispensable to sales promotion. They are as closely related as the lips and teeth, so to speak. What you produce is for sale on the market. It would be impossible to succeed in selling a product without first investigating the market.In the international market, goods on sale coming from different countries and suppliers are always facing keen competition;under such circumstances, they will try everything possible to familiarize themselves with the market conditions. In making investigations, we ought to get information about what similar items the competitors are offering on the market, what prices they are quoting, what features their products have, who are their regular customers, etc. Then, how can we obtain such information? There are many channels that we can make use of in doing this sort of work. The commercial counselor’s offices of our embassies stationed abroad can help us in making market investigations. Nowadays, our import and export corporations send their tarde groups abroad every now and then. One of their purposes is to make market surveys on the spot.Certainly, face-to-face talks with foreign businessmen are also important channels to get market information. The Chinese Export Commodities Fairs and some other fairs of similar nature as well as visits of foreign businessmen provide us with such opportunities. Of course, there are some other ways of making market investigations.56. In making market investigation, one should .A. get enough information concernedB. advertise his productsC. produce high quality goodsD. none of the above57. The word “indispensable” in the first line means .A. impossibleB. essentialC. advisableD. available58.Which of the following statements is NOT true?A. The relationship between market investigations and sales promotion is just as that of the lips and teeth.B. It is impossible to succeed in selling a product without market investigations.C. There are various ways of making market investigations.D. Production goes before the market investigation.59. Making market investigations is very important because .A. in the market, goods on sale are numerousB. every producer is facing keen competitionC. it can greatly promote salesD. all of the above60. All the following are channels to get market information EXCEPT .A. to have commercial counselor’s office of our embassies stationed abroadB. to promote the quality of our own productsC. to send trade groups abroad every now and thenD. to have face-to-face talks with foreign businessmenDGraduating hign school seniors looking to enter the workforce and other high school students searching for summer jobs are facing a tighter job market this year as the once red-hot U.S. economy continues to cool. Nationally, the jobless rate for 16-to 19-year-olds continues to rise. The unemployment rate for teenagers hit 14.2 percent in April, compared with 12.8percent last year, according to the U.S. Department of Labor.“It’s very obvious that it’s going to be a little harder this summer, because businesses are much more reserved and cautious,” said Mark J.Gambill, the vice president of marketing at Manpower Inc. the nation’s largest temporary employment agency. The New York City-based company recently surveyed 16,000 public and private employers. It found manufacturing, light industry, and high-tech firms were least likely to be seeking employees.Temporary jobs typically are the first to suffer in a slowing economy, but other sectors that employ teenagers heavily have fallen on leaner times as well. For instance, the amusement, recreation, and hotel industries shed a combined 43000 jobs in March and April, said John F.Stinson Jr., an economist at the U.S. Bureau of Labor Statistics.Ironically, the pinch comes as the nation’s overall jobless rate remains low. Statistics show that fewer teenagers have been jobless over the past few summers than at any time during the previous decade. “The jobless rates are still low by historical standards.”Mr. Stinson said. Ten years ago, for example, the unemployment rate for 16-to 19-year-old workers was 21.1 percent in June and 15.7 percent in July. Last year, the rate was 14.4 percent and 12.4 percent, respectively, federal figures show.Experts say teenagers looking for summer work still can find jobs but not lots of pay. The continuing slump in the nation’s high-tech sector and lingering uncertainty over the general health of the economy have combined to limit teenagers’ job options to the type of work that American typically have thrived on-the retail and fast-food industries.For the past several years, experts say, large numbers of teenagers found work with high –paying technology companies. But those heady days of $50000 starting salaries for those with computer skills and only a high school diploma have ended.Nationally, some 2.8 million students are expected to graduate from public and private high schools this year, according to the U.S. Department of Education. Lacking some sort of post secondary education or training virtually ensures those graduates will garner low wages. Ron Bird, the chief economist at the Employment Policy Foundation, a Washington-based nonprofit think tank, said economic projections show that wage growth for those with only a high school diploma will be the slowest among all groups.“There is a fundamental shift evident in the U.S.economy, tied primarily to technology, that will reward more professional, management, and technical-type jobs as opposed to line operators,” he said.61.According to the text, the current unemployment rate for teenagers isA. lower than ever beforeB.higher than in the previous decadeparable to the nation’s overall unemployment rateD.higher than it was last year62. Current job prospects for teenagers in the high-tech industry are .A.highly profitableB.in declineC. more promising than the retail industryD.virtually non – existent63. Which of the following individuals is NOT directly quoted in this text?A.The vice president of a temporary employment company.B.Analysts of the high-tech industry.C.An economist at a non-profit think tank.D.A government economist.64. Currently, most job opportunities for high school students and graduates are available inA. the high-tech sectorB. temporary employmentC.retail storesD.amusement parks65.This text is mainly about .A. the cooling of the U.S. economyB. job competition between high school students and high school graduatesC. summer jobs prospects for teenagersD.employment prospects for high school students and graduates四.Reading comprehension II(15points):Directions: Put in the blanks of the following sentences the numbers of the phrases shown below which give the sentences the correct meaning.The years after the cessation of hostilities with victory have not brought us peace; rather, 66 ,They have made us aware 67 us from its realization. There is hardly yet any sign that we have found the kind of equilibrium, political or economic or social, 68 and security 69 they gain confidence in themselves and faith in the good-will of their neighbours.

But it is hardly excessive to say that, 78 the immense Russian progress since 1917, there is a major element in the technology of production 79 could not hope even to rival the present American standards; and there is no inherent reason to suppose that, 80 , the difference will not be at least as great asit is at the present time.①the younger generations ②a generation from now ③has been added④has added ⑤surpass ⑥surprised⑦save ⑧had ⑨has⑪lose ⑫either ⑬also⑭in spite of ⑮instead of ○16regardless of○17with a view to ○18on the contrary ○19to which○20out of which ○21how long and hard the road is which separates○22in which the government in Moscow ○23in the age when the aeroplane may carry ○24which gives men that sense of ease ○25under the control of a single government 五.Mistake Detection(10 points):I cannot conceive education in a training in so many separate subjects. 81.Education is integral: it is encouragement of the growth of the whole man, 82.the complete man. It follows that it is not entire, nor even mainly, an affair 83.of book learning, for what is only the education of one part of our nature 84.–that part of the mind which deals with concept and abstractions. 85.In the child, who is not yet mature enough to think by these shortcut 86.methods, it should be large an education of the senses- the sense 87.of sight,touch and hearing: in one word, the education of the sensibility. 88.From this point of view there is valid distinction between art and science: it 89.is only the whole man with his diverse interests and faculties, and the aim 90.of education should be develop all these to harmony and completeness.。

These “little camels”of the Andes were the only burden bearers the Incas had in the four hundred years when they were extending theirempire from Peru to Chile and northward to Quito. These animals could live at altitudes of over two and one-half miles above sea level where in the later days the horses and mules of the conquerors would die of mountain sickness.Over this road, if a llama path can be called a road, a single explorer or trader went now and again in the days of the Spanish conquerors . But the traveled route across the continent was farther north, across form Peruto Upper Peru (now Bolivia),through western Paraguay, and then down to Buenos Aires. The southern Andes practically shut the door between Chile and Argentina.46. The Uspallata Pass isA.so steep and narrow that no man has ever conquered.B.one of many famous spots of the Andes that were conquered by man .C.famous because one can command a fine view of Chile and Argentina.D. the most well-known path of the Andes because of its steepness conquered by man .47.The “little camels”meansA.camels with small humps.B.beasts of buren like small camelsC.small animals used as burden bearers in Peru, Chile and Argentina since four hundred yearsago.D.the only animals the Incas had.48.The passage states that these “little camels”couldA.travel long distances without water.B.travel long distances without rest.C. live at high altitudes.D.carry extremely heavy loads.49.The word “their”in line 4 refers toA.Indians.B.white men.C.llamas.D.burden bearers.50.the writer of this passage probably goes on to tell howA munication has been improved beween Chile and Argentina.B.even before the Incas there was a trail across the pass.C.the Andes still prevent travel between Chile and Argentina.D.Argentina for a long time opposed easy travel to Chile.BBefore World War II, our interest in the Far East was casual and sporadic. To be sure, Commodore Perry had opened Japan in 1853, and after the turn of the century we tried to keep the door open in China by diplomaticefforts. Our cultural and economic relations were more important than our political activities. We introduced Christianity, Concord grapes, and cash registers to the area. In turn ,we decorated our American homes with Japanses prints and Chinese jade, we wore Far Eastern silk, and we drank Formosa tea.Beseball because the Japanese national game and American universities had school named after them in China.But the Far East really was far ; and it was different. Its languages, spoken and written, were completely unfamiliar. Its religions were concerned with different gods, different forms of worship, and different explanations of the purpose of life. Its organizations-government, school, and family-rested on a different basis of authority. Even its people had different characteristics and capabilities.Nor did we make any great effort to learn about the Far East. The attention of our education system and most of our scholars was concentrated upon our immediate society and its origin. This enterprise carried used across the Atlantic, and we studied European history and culture. We pursuedour cultural ancestry back to the Greek, the Romans,and the Hebrews. But the usual college graduate knew more about the moon than he did about Korea,more about the early Romans than he did about contemporary China. –Willard Thop—51. Before World War IIA.political activities were far more important than cultural activities.B.American universities had schools nameds after them in China.C.the Far East was an important area for growing grapes.D.Japan introduced cash registers into China.52.The main idea of these paragraphs is thatA.there was not a close relationship between the United States and the Far East beforeWorld War II.B.Since Commondore Perry opened Japan in 1853 many western ideas have been introduced into Japan.C.though there had been some cultural relations, the Far was still very different from the West.D.Americans were not interested in the Far East.53.The lack of interest in the Far East was a result ofA.the attitude toward the Far East that it had little true culture worth studying.B.a recongnition that Far Eastern culture was different.C.the priority given to one’s own society and its origins.D.the little contact because of distance.54.To “keep the door open in China”means toA.protect vested interests of the colonial powers.B.maintain diplomatic exchanges of personnel.C.continue commercial and cultural relationships.D.prevent efforts to keep us out of China.55.Far eastern religions were characterized as—A.interested in Christianity.B.unlike those in west .C.related to their basis of authority.D.casual and unrelated to language..CThe market investigation is indispensable to sales promotion. They are as closely related as the lips and teeth, so to speak. What you produce is for sale on the market. It would be impossible to succeed in selling a product without first investigating the market.In the international market, goods on sale coming from different countries and suppliers are always facingkeen competition;under such circumstances, they will try everything possible to familiarize themselves with the market conditions. In making investigations, we ought to get information about what similar items the competitors are offering on the market, what prices they are quoting, what features their products have, who are their regular customers, etc. Then, how can we obtain such information? There are many channels that we can make use of in doing this sort of work. The commercial counselor’s offices of our embassies stationed abroad can help us in making market investigations. Nowadays, our import and export corporations send their tarde groups abroad every now and then. One of their purposes is to make market surveys on the spot.Certainly, face-to-face talks with foreign businessmen are also important channels to get market information. The Chinese Export Commodities Fairs and some other fairs of similar nature as well as visits of foreign businessmen provide us with such opportunities. Of course, there are some other ways of making market investigations.56. In making market investigation, one should .A. get enough information concernedB. advertise his productsC. produce high quality goodsD. none of the above57. The word “indispensable” in the first line means .A. impossibleB. essentialC. advisableD. available58.Which of the following statements is NOT true?A. The relationship between market investigations and sales promotion is just as that of the lips and teeth.B. It is impossible to succeed in selling a product without market investigations.C. There are various ways of making market investigations.D. Production goes before the market investigation.59. Making market investigations is very important because .A. in the market, goods on sale are numerousB. every producer is facing keen competitionC. it can greatly promote salesD. all of the above60. All the following are channels to get market information EXCEPT .A. to have commercial counselor’s office of our embassies stationed abroadB. to promote the quality of our own productsC. to send trade groups abroad every now and thenD. to have face-to-face talks with foreign businessmenDGraduating hign school seniors looking to enter the workforce and other high school students searching for summer jobs are facing a tighter job market this year as the once red-hot U.S. economy continues to cool. Nationally, the jobless rate for 16-to 19-year-olds continues to rise. The unemployment rate for teenagers hit 14.2 percent in April, compared with 12.8percent last year, according to the U.S. Department of Labor.“It’s very obvious that it’s going to be a little harder this summer, because businesses are much more reserved and cautious,” said Mark J.Gambill, the vice president of marketing at Manpower Inc. the nation’s largest temporary employment agency. The New York City-based company recently surveyed 16,000 public and private employers. It found manufacturing, light industry, and high-tech firms were least likely to be seeking employees.Temporary jobs typically are the first to suffer in a slowing economy, but other sectors that employ teenagers heavily have fallen on leaner times as well. For instance, the amusement, recreation, and hotel industries shed a combined 43000jobs in March and April, said John F.Stinson Jr.,an economist at the U.S. Bureau of Labor Statistics.Ironically, the pinch comes as the nation’s overall jobless rate remains low. Statistics show that fewer teenagers have been jobless over the past few summers than at any time during the previous decade. “The joblessrates are still low by historical standards.” Mr. Stinson said. Ten years ago, for example, the unemployment rate for 16-to 19-year-old workers was 21.1percent in June and 15.7percent in July. Last year, the rate was 14.4percent and 12.4percent, respectively, federal figures show.Experts say teenagers looking for summer work still can find jobs but not lots of pay. The continuing slump in the nation’s high-tech sector and lingering uncertainty over the general health of the economy have combined to limit teenagers’ job options to the type of work that American typically have thrived on-the retail and fast-food industries.For the past several years, experts say, large numbers of teenagers found work with high –paying technology companies. But those heady days of $50000 starting salaries for those with computer skills and only a high school diploma have ended.Nationally, some 2.8million students are expected to graduate from public and private high schools this year, according to the U.S. Department of Education. Lacking some sort of post secondary education or training virtually ensures those graduates will garner low wages. Ron Bird, the chief economist at the Employment Policy Foundation, a Washington-based nonprofit think tank, said economic projections show that wage growth for those with only a high school diploma will be the slowest among all groups.“There is a fundamental shift evident in the U.S.economy, tied primarily to technology, that will reward more professional, management, and technical-type jobs as opposed to line operators,”he said.61.According to the text, the current unemployment rate for teenagers isA. lower than ever beforeB.higher than in the previous decadeC parable to the nation’s overall unemployment rateD.higher than it was last year62. Current job prospects for teenagers in the high-tech industry are .A.highly profitableB.in declineC. more promising than the retail industryD.virtually non – existent63. Which of the following individuals is NOT directly quoted in this text?A.The vice president of a temporary employment company.B.Analysts of the high-tech industry.C.An economist at a non-profit think tank.D.A government economist.64. Currently, most job opportunities for high school students and graduates are available inA. the high-tech sectorB. temporary employmentC.retail storesD.amusement parks65.This text is mainly about .A. the cooling of the U.S. economyB. job competition between high school students and high school graduatesC. summer jobs prospects for teenagersD.employment prospects for high school students and graduates四.Reading comprehension II(15points):Directions: Put in the blanks of the following sentences the numbers of the phrases shown below which give the sentences the correct meaning.The years after the cessation of hostilities with victory have not brought us peace; rather, 66,They have made us aware 67 us from its realization.
