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. It is, indeed, one of the major sources of doubt and fear that, 70 an atomic bomb. Across practically the whole world.

Never 74 so much of the world’s productive power been concentrated standards so far outdistanced that of any possible rival. Soviet Russia has larger man-power, and it may be, productive resources which, when developed, will rival, perhaps, 77 , those of the United States. 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.。

Each passage is followed by some questions or unfinished statements. For each of them there are four suggested answers marked A, B, C and D. Choose the best answer to each question. Please mark the corresponding letter for each item on the Answer Sheet.Passage 1The family in the western world has changed greatly during the last two centuries. Social scientists say this is one of the important changes from a traditional society to a modern society. Before the nineteenth century, families usually arranged marriages for their children. Young people did not decide whom they wanted to marry. After they got married, they usually had a lot of children. This family was an important part of the large family of aunts, uncles, cousins, grandparents, and other relatives.By the nineteenth century, most young people could choose whom they wanted to marry. Marriages joined two people and not two families. The reason why two people got married was because they loved each other.At the same time, parents began to realize that they had to take very good care of their children. They had to take care of their health and try to give them an education. Before this, most people did not go to school. But now education was necessary for a good life.The parents decided they should have fewer children as they could give each one a good life. They thought it was important for the mother to spend as much time as possible with her children. Before, the family all worked together at home. After 1800s more fathers worked outside the home for money. Mothers stayed home and had greater control of the home and children.Family life is changing even faster in the United States today. There is almost one divorce for every two marriages. Over 10 percent of families have a mother and children but no father. At least half of all children will live part of the time with only one parent. 50 percent of all mothers work outside the home.In Canada people are getting divorced and remarried more often. They are havingfewer children. This is having a powerful effect on a country where change has usuallybeen slow. Some social scientists think that soon there will be no family life in the United States as we know it today. They do not know how people will live. Others think society needs families, and we will always have them.注意：此部分试题请在答题卡上作答。

The smiles soon faded from their faces, however, when Lyon reported that the earth indicator compass—the most valuable navigational instrument on board—was out of action. They would have to rely on their magnetic steering compasses. Nevertheless, as they settled down to their nocturnal watch, flying at 4,000 feet in perfect weather, they felt happy about the relatively simple journey that lay ahead—but it was a happiness that was all too short-lived.The moon disappeared and the atmosphere gradually grew colder. Strong gusts of wind which rocked the plane were followed by the drumming of torrential rain. Pitching and tossing as they flew on blindly, they circled, climbed and plunged in an attempt to dodge the squalls. Navigation was out of the question. Kingsford Smith, fighting the controls, had but one thought—to keep the Southern Cross airborne. From early evening till the small hours, they were simple fighting to survive, their limbs stiffening, their hands too numb to write. There was no entry in the log from 6.15 p.m to 3.20 a.m.Soon after dawn , they managed to escape from that terrible electric storm and at 7 a.m., Warner picked up a radio beam from Brisbane. With this they altered course, comforted by flying into warmer air. At last they sighted the Australian coast, more than a hundred miles south of their course.36. Which is the destination of the flight?A) Australian coast B) Kingsford-SmithC) Southern Cross D) Brisbane37. What does the passage tell us?A) The story of the great flight.B) The struggle between man and nature.C) The adventures of the great flight.D) The experiences before a perfect landing.38. What kind of conclusion can we draw from the last paragraph but one?A) Pilots are supposed to keep written records of a journey during the flight.B) Pilots should be mentally prepared for all kinds of situations appearing.C) Pilots should listen to the weather report before take-off.D) pilots should wear special overalls so as to keep themselves warm enough.39. “It was a happiness that was all too short –lived.” Why ? Because .A) magnetic steering compasses were out of actionB) the weather did not promiseC) the journey did not turn out as they had expectedD) they met with unfavorable weather condition40 Which disaster comes first during the course of the flight?A) Strong gusts of wind. B) Terrible electric storm.C) Cold atmosphere. D) The earth indicator compass was out of action.Question 41 to 45 are based on the following passage:Is staring at a big, white wall during class making you feel dull? If you have ever walked past math teacher Mr. Kelley's room, you may have noticed how cheerful it is throughout the year. One thing that makes his classroom so much fun is the celebrity (名人) pictures on his front wall.Kelley's students have been writing to celebrities from across the nation asking for a photo and a few words of advice. "It really takes a lot of time and money," Kelley said. First, Kelley and his students make a list of all the celebrities to whom they want to write. Once a student picks a star, Kelley looks them up in his book of addresses to see if he can write to that person.Writing to the stars takes a lot of time because he has to personalize each letter, print them out, and address them. In the letter, Kelley asks the celebrity to send his classes a picture with some advice he or she would give to today's youth.Kelley takes up a collection in all of his classes and asks each student to contribute (捐) dollar to pay for the postage. Once Kelley mails off all the letters, the fun really begins. So far he has gotten back about 20 letters and pictures. "The only thing that isn't cool is when the celebrity sends the picture back with no advice on it, which is my entire purpose in doing this," said Kelley. When he gets at least three pictures returned, he lets his classes guess who the three stars are. He keeps score of how many celebrities each class has guessed. Jason Bryant, a student, said, "It's become a contest(竞赛) between the classes to see who can guess the most stars, and it's really fun."41. Who pays to send out letters?A）Kelley himself B）Kelley's studentsC）The contest organizer D）Jason Bryant42. What is the text about?A）Celebrities sending photos to KelleyB）Celebrities giving advice to studentsC）Kelley and his classes writing to celebritiesD）Kelley inviting celebrities to his classes43. According to Jason Bryant, they find a lot of fun inA）studying math B）reading repliesC）the name-guessing game D）receiving pictures from celebrities44. What is Kelley's main purpose of writing the letters?A）To educate his students B）To have pictures for his office wallC）To improve his students' letter writing skillsD）To help his students know more about the celebrities45. The phrase "to personalize each letter" (Line 1, Para.3 ) means"______".A）to print out each otherB）to personally send out each otherC）to find the address of each celebrityD）to make the letter suitable for a particular starPart ⅢCloseDirections: There are 20 blanks in the following passage. For each blank there are four choices marked A), B), C), D). You should choose the ONE that best fits into the passage.

In my second year the professor who taught the course passed away and I was asked to take over. Then for many years I taught classes for judges, law students, and practicing lawyers throughout the country. After graduation, I got a job as an assistant city attorney. Then I became one of Denver’s youngest judges at the age of 28. Finally, I did return to Boulder---- to receive the University of Colorado’s George Norlin Award.Sooner or later everyone will fall short at something important to them.

B ∥，取11A B ，11B C 的中点分别为H G ，，连接EH BG GH GF AC ，，，，，如图所示，则11GF A B ∥， 所以GF l ∥所以异面直线EF 与所成的角为GFE ∠或其补角，又因为AB =12AA =，所以14AC =，1EH =，HP GP ==所以2EG EF -=，所以22cos 24GF GFE RP ∠==.【解题方法】本题以三棱柱为载体，综合考查异面直线所成角的概念.解答的基本方法是通过平移直线，把异面直线平移到两条相交直线上，明确异面直线所成角的概念，应用三角函数知识求解，充分利用图形特征，则可事半功倍.例如本题利用图形易得11D A B ∥，这是本题的题眼. 17.解：本题考查线性回归方程. （1）由题中数据计算得1(12345)35t =++++=， ()2223215(2)(1)01210i i i a t =---+-+++=∑，由参考数据知，()()51311iii t t y y =--=∑，所以()()()532131131.110iiiii tty y b tt=--=-=-∑∑，$214.2-31.13120.9ay bt --=⨯=$， 故所求回归方程为31.1120.9yt =+.（2）将2021年对应的7t

项和问题，是高考的常考内容，解题过程中要注意应用函数与方程思想，构建方程（或方程组）求基本量，例如此题，从已知出发，构建1,a d 的方程组求数列通项公式，利用前后项合并，构造等差数列，求数列的前n 项和. 19.解：本题考查线面平行及多面体的体积.（1）证明：因为2BC AD AD BC E =∥，，为线段AD 的中点，所以BC AE ∥，连接EC ，因为AB AD ⊥，所以四边形ABCE 为矩形，连接BE 交AC 于点O ，连GO ，因为G 为线段PB 的中点，所以OG PE ∥，因为GO ⊄平面PEF ，PBC 平面PEF ， 所以GO ∥平面PEF ，由题易知，AC ∥平面PEF ， 又因为GC ⊂平面GAC ，AC ⊂平面GAC .AC GO O =I ，所以平面PEF ∥平面GAC ，又因为AGC 平面GMC ，所以直线AC ∥平面PEF .（2）因为22 2 AD BC PA ===，1AB =，所以四棱锥P ABCD -的体积111(12)11322S =⨯⨯+⨯⨯=，三棱锥G ABC -的体联11111132212S =⨯⨯⨯⨯=，棱锥P DEF -的体积 11111132212S =⨯⨯⨯⨯=，故所求多面体AGCPEF 的体积为1111212123--=.20.解：本题考查函数最值及恒成立求参数范围. （1）()21x f x e ax '=--，所以()21xg x eax =--，()2x g x e a '=-，①当0a ≤时，()0g x '>，所以()21x g x e ax =--在R 上单词递增，不合题意；②当0a >时，(,ln 2)x a ∈-∞，()0g x '<，(ln 2,)x a ∈+∞，()0g x '>， 所以函数()gx 在区间(,ln 2)a -∞上单调递减，在区间(ln 2,)a +∞上单调递增，()(ln 2)2(1ln 2)10g x g a a a ----…，令()ln 1x x x x μ'---，则()ln x x μ'=-，所以()x μ在区间()0,1上单调递增，在区间(1,)+∞上单调递减，所以()()10x μμ≤=，所以由2(1ln 2)10a a --=，解得12a =， 即实数a 的值为12. （2）因为0x ∀>，2()(1)(1)1f x a x a x >--++恒成立，所以210x e x ax -+-≥，即21x e x a x ---<对任意0x >恒成立，令21()x e x x xϕ---，则()2(1)1()x x e x x x ϕ---'=，由（1）知，10x e x --≥，当且仅当0x =时，等号成立，所以函数()x ϕ在区间()0,1上单调递减，在区间(1,)+∞上单词递增，所以()(1)2x e ϕϕ=-…，所以2a e -≤-，即2a e ≥-. 所以实数a 的取值范围为[2,)e -+∞. 21.解：本题考查抛物线的性质. （1）因为||10PF =，所以8102p+-，解得4p =，所以()0,2F ， 因为288t =⨯，且0t <，所以8t =-，所以()8,8P -，故直线PF 的方程为822(0)80y x ------， 化简得3480x y

y⎧--⎪⎪⎨⎪=-⎪⎩，得直线l 的方程为3314y xx y =-，又因为直线l 过点()0,4，所以4y =-，即点G 在定直线4y =-上，所以PG 的最小值为()8412--=.【解题思路】解决直线与抛物线的综合问题时，需要注意：（1）观察、应用题设中的每一个条件，明确确定直线、抛物线的条件；（2）强化有关直线与抛物线联立得出一元二次方程后的运算能力，重视根与系数之间的关系、弦长、斜率、三角形的面积等问题.22.解：本题考查坐标与参数方程： （1）由题知，曲线C 的直角坐标方程为224x y +=，直线l20y m -+=，因为直线l 与曲线C||2m =≥， 所以实数m 的取值范围为(,2][2,)-∞-+∞U . （2）设()()1122,,,,(,)Ax y B x y P u v ，由（1）知，(2,2)m ∈-，由22204y m x y -+=+=⎪⎩，解得224440x m ++-=，所以122u x x -+-=，)121224v y y x x m m -+++=，所以2u =-，即u
