He returned from his first 1 to the place in late autumn,and could not get back until the snows melted（融化） in the following 2 .Then he went to the pilot of a small plane,who earned his living by 3 hunters over parts of the country 4 were no roads and no railways,and asked him to take him back to his 5 piece of forest. The pilot did not know the place,so the hunter 6 it to him on the map.“ 7 there is nowhere to land there,man!” said the pilot.“I have flown 8 that part of the country on my way to other places,and I know that we can’t land anywhere between this river and these mountains.” “I thought you were a 9 pilot,” said the hunter.“Some of my friends said you could land a plane on a stamp.” “That’s 10 ,”answered the pilot.“I can land a plane where nobody else can.But I 11 you there is nowhere to land in the place you are talking about.” “And what if I tell you that another pilot 12 land me there last spring?”said the hunter. “Is that 13 ?” asked the pilot. “Yes,it is.I swear（起誓）it.” Well,this pilot could not let himself be 14 by another,so he agreed to take the hunter. When they reached the place;the hunter 15 out a small spot（地點(diǎn)） without trees in the middle of the forest,with a steep rise（陡峻的斜坡） at one end.The pilot thought that there was 16 room to land there,but the hunter said that the other pilot had done so the year before,so 17 went to the plane.When it came to the rise,it turned right over on to its 18 .As the hunter climbed out,he 19 and said,“Yes,that is exactly how the other pilot managed 20 last time.” 1.A.voyage B.entrance C.way D.visit 解析：搭配問(wèn)題，用排除法和比較法。首先排除B項(xiàng)，A、C、D三項(xiàng)作名詞用時(shí)皆可接to，但voyage意為“航海，航行”，way意為“方式，方法，道路”；visit意為“參觀，訪問(wèn)，到（某地）”，比較A、C、D的意思，顯然D項(xiàng)符合題意。僅考慮搭配結(jié)構(gòu)，不注意所要表達(dá)的上下文意思會(huì)造成誤選。 答案：D 2.A.spring B.summer C.autumn D.winter 解析：生活常識(shí)問(wèn)題，用直接法。一般說(shuō)來(lái)，（頭年）秋冬積雪，來(lái)年春天融化，顯然選A項(xiàng)。 答案：A 3.A.bringing B.taking C.carrying D.fetching 解析：詞語(yǔ)辨析問(wèn)題，用比較法。這四個(gè)動(dòng)詞有明確的方向性，bring意為“拿來(lái)，帶來(lái)”；take意為“拿走，帶走”；carry意為“攜帶，搬運(yùn)”；fetch意為“去取回，去拿來(lái)”。比較四個(gè)詞可知，應(yīng)選C項(xiàng)。 答案：C 4.A.where B.where there C.there D.there where 解析：從句與搭配問(wèn)題，用直接法。顯然此句是由關(guān)系副詞where引導(dǎo)的定語(yǔ)從句，另一方面“there be”為固定搭配，故應(yīng)選B項(xiàng)。 答案：B 5.A.comfortable B.favourite C.precious D.dangerous 解析：上下文語(yǔ)境問(wèn)題，用直接法或排除法。短文第一句話提示：獵人發(fā)現(xiàn)一處有眾多動(dòng)物的森林，這對(duì)于以捕獵為生的獵人來(lái)說(shuō)無(wú)疑是再理想不過(guò)了。A、C、D三項(xiàng)與題意不符，故排除。另一方面，favourite意為“最佳的、合適的、理想的”，與語(yǔ)境題意相符。 答案：B 6.A.referred B.introduced C.pointed D.showed 解析：搭配問(wèn)題，用排除法或比較法。首先排除A、C兩項(xiàng)，introduce sth.to sb.意為“把某物介紹給某人”，或“讓某人熟悉某物”，show sth.to sb.意為“給某人看某物”。此處由于飛行員不知道森林中的具體位置，因此獵人在地圖上指明其位置，比較B、D兩項(xiàng)，知D為正確選項(xiàng)。 答案：D 7.A.Instead B.Therefore C.But D.However 解析：連詞問(wèn)題，用排除法。通過(guò)兩個(gè)人對(duì)話的語(yǔ)境可以判斷該處缺少轉(zhuǎn)折關(guān)系的連詞，A、B兩項(xiàng)為副詞，應(yīng)排除。however在行文中常常伴有逗號(hào)，這是however用法的重要標(biāo)志；but用在句首時(shí)不用逗號(hào)作為標(biāo)志。故應(yīng)選C項(xiàng)。 答案：C 8.A.over B.through C.across D.beyond 解析：上下文語(yǔ)境問(wèn)題，用直接法。此處與上文“by carrying hunters over parts of the country”相對(duì)應(yīng)，故選A項(xiàng)。 答案：A 9.A.common B.ordinary C.excellent D.wonderful 解析：語(yǔ)境問(wèn)題，用排除法。ordinary和excellent都是以元音音素發(fā)音開(kāi)頭，前面的冠詞應(yīng)為an，這與題目相違背，故應(yīng)排除B、C兩項(xiàng)。獵人要想讓飛行員找到他理想的森林地帶，他應(yīng)該對(duì)飛行員講一些恭維之類(lèi)的言語(yǔ)，以博得飛行員的好感，故應(yīng)排除A項(xiàng)，那么只有D為正確選項(xiàng)。 答案：D 10.A.false B.right C.actual D.sure 解析：語(yǔ)境問(wèn)題，用直接法。“That’s right”，一方面是習(xí)慣表達(dá)法，A、C、D三項(xiàng)一般不這樣表述；另一方面，通過(guò)上文的意思可知，飛行員對(duì)自己的駕駛技術(shù)和水平充滿(mǎn)自信，故應(yīng)選擇B項(xiàng)。 答案：B 11.A.tell B.announce C.persuade D.prevent 解析：詞語(yǔ)用法問(wèn)題，用直接法或排除法。A項(xiàng)的用法是“tell sb./sth.”或“tell sb.+clause”，B項(xiàng)的用法是“announce to sb.that clause”,C項(xiàng)為“persuade sb.（not） to do sth.”，D項(xiàng)為“prevent sb./sth.（from） doing sth.”，A 項(xiàng)此處可譯為“我實(shí)話告訴你……”。 答案：A 12.A.had to B.did C.should D.would 解析：語(yǔ)境語(yǔ)氣問(wèn)題，用直接法。由獵人說(shuō)話的語(yǔ)氣可以判斷，此處應(yīng)該選擇“did”，表示強(qiáng)調(diào)語(yǔ)氣。 答案：B 13.A.perfect B.funny C.true D.pleasant 解析：語(yǔ)境語(yǔ)氣問(wèn)題，用直接法。此處可以判斷飛行員對(duì)獵人說(shuō)話的真實(shí)性表示懷疑，故選C項(xiàng)。 答案：C 14.A.hit B.struck C.attacked D.beaten 解析：詞語(yǔ)辨析問(wèn)題，用排除法。hit意為“打擊、碰撞、襲擊”，strike意為“敲打、攻擊、鑄造”，attack意為“攻擊、抨擊、侵襲”，beat意為“敲打；敲擊、打敗”。我們常用defeat sb.或 beat sb.表示“打敗、擊敗某人”。顯然，飛行員決不愿意讓他人超過(guò)自己，故應(yīng)排除A、B、C三項(xiàng)，D為正確答案。 答案：D 15.A.carried B.took C.pointed D.worked 解析：詞組辨析問(wèn)題，用排除法或直接法。此處原文的意思是：當(dāng)他們快要到達(dá)森林時(shí)，獵人用手指了指森林中一小塊沒(méi)有樹(shù)的地方。carry out意為“執(zhí)行、完成、實(shí)施”，take out意為“取出、拿出”，point out意為“指點(diǎn)、指明、指出”，work out意為“得出、計(jì)算出”。經(jīng)過(guò)分析可知，C為正確選項(xiàng)。 答案：C 16.A.much B.not enough C.a little D.enough 解析：語(yǔ)意問(wèn)題，用直接法。根據(jù)語(yǔ)句的意思，不難得出B項(xiàng)為正確答案。 答案：B 17.A.down B.up C.over D.under 解析：語(yǔ)境問(wèn)題，用直接法。原文大意是：飛行員覺(jué)得著陸的空間不夠，然而獵人則堅(jiān)持說(shuō)別的飛行員就是在這樣的情況下著陸的，無(wú)奈飛行員只能將飛機(jī)下飛著陸。A項(xiàng)為正確答案。 答案：A 18.A.stomach B.back C.shoulder D.leg 解析：語(yǔ)境問(wèn)題，用排除法或比較法。顯然C、D兩項(xiàng)不符合實(shí)際應(yīng)排除。stomach意為“腹部”；back意為“背部”，另外onto one’s back常連用，故應(yīng)排除A項(xiàng)，B項(xiàng)為正確答案。 答案：B 19.A.smiled happily B.shouted angrily C.whispered anxiously D.cried curiously 解析：語(yǔ)境問(wèn)題，用直接法。讀到此處，讀者應(yīng)該領(lǐng)會(huì)到獵人目的或計(jì)劃已經(jīng)達(dá)到，當(dāng)然是“高興地笑了”，故選A項(xiàng)。 答案：A 20.A.me B.us C.it D.him 解析：搭配問(wèn)題，用直接法。manage it是指“上次，那位飛行員剛好就是這么做的”。另一方面，我們?cè)诮浑H中也常常有這樣的一句話。No，thanks.I can manage it myself.意思是“不用，謝謝。我自己能夠應(yīng)付”，故選C項(xiàng)。 答案：C 閱讀理解 A In 1723 there arrived in Philadelphia a penniless young man,eager for work and for knowledge.As the years passed,this man,Benjamin Franklin,contributed greatly to his city and to his country.He became a printer and a publisher,and a learned man in many subjects.He also helped to spread learning by establishing a public library and by founding the American Philosophical Society,which is an important academy of great scholars to this day. Franklin initiated many improvements in the city of Philadelphia,making it one of the world’s first cities to have paved and lighted streets as well as a police force and a fire-fighting company.He also made many practical inventions such as the Franklin stove,which was a very efficient heater,and the lightning road to protect buildings in electric storms.His scientific work with electricity earned Franklin world fame. Franklin played an important role in the early history of the United States.He took part in drawing up the Declaration of Independence and the Constitution.He was the first ambassador to France,and he helped negotiate the treaty of 1783,which ended the Revolutionary War. As an active member and as president of the Abolitionist Society,Franklin devoted the last years of his life to the movement to end slavery. 1.When Franklin arrived in Philadelphia,he had . A.a little money but no work B.no money and no work C.a job and a lot of knowledge D.a job and a lot of money 解析：從文章第一段 “...penniless...eager for work and knowledge”可知答案。 答案：B 2.The American Philosophical Society is an important academy of great scholars . A.at Franklin’s time B.until he died C.up to now D.before the birth of the USA 解析：從第一段最后一句“...to this day”可知答案為 C。 答案：C 3.Franklin became famous because he . A.invented the lightning road to protect buildings in electric storms B.was the first ambassador to France C.took part in drawing up the Declaration of Independence and the Constitution D.was president of the Abolitionist Society 解析：從第二段最后一句話“His scientific work with electricity earned Franklin world fame”可知答案。 答案：A 4.“He also made many practical inventions...” means he . A.imagined lots of useful things B.made clever things C.invented a lot of useful objects D.invented a lot of expensive things 解析：猜測(cè)詞義題。practical “實(shí)用的”。 答案：C B Scattered around the globe are more than 100 small regions of isolated volcanic activity known to geologists as hot spots.Unlike most of the world’s volcanoes,they are not always found at the boundaries of the great drifting plates that make up the earth’s surface;on the contrary,many of them lie deep in the interior of a plate.Most of the hot spots move only slowly,and in some cases,the movement of the plates past them has left trails of dead volcanoes.The hot spots and their volcanic trails are milestones that mark the passage of the plates. That the plates are moving is now beyond dispute.Africa and South America,for example,are moving away from each other as new material is injected into the sea floor between them.The complimentary coastlines and certain geological features that seem to span the ocean are reminders of where the two continents were once joined.The relative motion of the plates carrying these continents has been constructed in detail,but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earth’s interior.It is not possible to determine whether both continents are moving in opposite directions or whether one continent is stationary and the other is drifting away from it.Hot spots,anchored in the deeper layers of the earth,provide the measuring instruments needed to resolve the question.For an analysis of the hot-spot population it appears that the African plate is stationary and that it has not moved during the past 30 million years. The significance of hot spots is not confined to their role as a frame of reference.It now appears that they also have an important influence on the geophysical processes that propel the plates across the globe.When a continental plate comes to rest over a hot spot,the material rising from deeper layers creates a broad dome.As the dome grows,it develops deep fissures（cracks）;in at least a few cases the continent may break entirely along some of these fissures,so that the hot spot initiates the formation of a new ocean.Thus just as earlier theories have explained the mobility of the continents,so hot spots may explain their mutability（inconstancy）. 本文闡述地理知識(shí)。文章中作者陳述了火山發(fā)生的原因在于地球的地殼運(yùn)動(dòng)。整個(gè)地球內(nèi)部有100多個(gè)互相分離的火山活動(dòng)區(qū)域,其中大部分位于地球板塊深處，地質(zhì)學(xué)家稱(chēng)這些區(qū)域?yàn)闊狳c(diǎn)。板塊流動(dòng)經(jīng)過(guò)熱點(diǎn)，留下軌跡。因此熱點(diǎn)使我們了解哪一個(gè)板塊是靜止或流動(dòng)的。 1.The author believes that . A.the motion of the plates corresponds to that of the earth’s interior B.the geological theory about drifting plates has been proved to be true C.the hot spots and the plates move slowly in opposite direction D.the movement of hot spots proves the continents are moving apart 解析：本題為段落理解題。第一段最后一句：熱點(diǎn)和它們的火山軌跡表明板塊是流動(dòng)的。第二段第一句指出板塊的流動(dòng)是不可爭(zhēng)議的。 答案：B 2.That Africa and South America were once joined can be deduced from the fact that . A.the two continents are still moving in opposite directions B.they have been found to share certain geological features C.the African plate has been stable for 30 million years D.over 100 hot spots are scattered all around the globe 解析：本題考查對(duì)段落的理解。第二段第三句：大洋兩邊，非洲和南美洲海岸線的互補(bǔ)性及某些地貌都顯示出兩大洲一度銜接在一起。 答案：B 3.The hot-spot theory may prove useful in explaining . A.the structure of the African plates B.the revival of dead volcanoes C.the mobility of the continents D.the formation of new oceans 解析：本題為段落理解題。第三段闡述了由于熱點(diǎn)的作用，大洋是如何形成的。 答案：D 4.The passage is mainly about . A.the features of volcanic activities B.the importance of the theory about drifting plates C.the significance of hot spots in geophysical studies D.the process of the formation of volcanoes 解析：本題考查綜合理解能力。本文主要論述了熱點(diǎn)在地質(zhì)形成過(guò)程中的重要作用。 答案：D C Sabine Island,near Greenland,was first discovered by the British geographer Sir Edward Sabine in 1823,but an 1869 map showed it was actually a quarter of a mile farther west than its discoverer had mapped.This interested Alfred Wegener,a young geographer working in Greenland in 1910.He thought the error was too great to be explained. Wegener himself took measurements and found that since 1869 the island had moved another five-eighth of a mile.After checking the position of other Arctic landmasses,he concluded that all of them were drifting westward at different speeds. From this finding,Wegener developed his floating continent theory.He imagined an original super-continent making up the infant（未成年的） earth,finally the mass broke up into several pieces—the present continents.The continents do seem to fit together like pieces of a puzzle,and what’s more,some of the mountain ranges（山脈） of different continents line up rather well,as if the landmasses were at one time connected.However,believable as Wegener’s argument appeared,many geographers refused to accept it.Exactly how the continents were formed is still a leading mystery in geography,though today many geographers are returning to the continental drift theory. 1.Sabine Island was first discovered and mapped by . A.the map makers of 1869 B.geographers of Greenland C.a British geographer D.Alfred Wegener 解析：本題為細(xì)節(jié)題。文章第一句“Sabine Island...was first discovered by the British geographer”以及“but an 1869 map showed it was actually a quarter of a mile farther west than its discoverer had mapped”可知，英國(guó)地理學(xué)家Sir Edward不僅發(fā)現(xiàn)了Sabine Island，而且繪制了地圖。 答案：C 2.Wegener’s discovery led him to conclude that . A.both the two earlier maps were in error B.the Arctic landmasses were slowly drifting westward C.all the continents were drifting slowly away from one another D.Sabine Island was one part of Greenland 解析：本題為細(xì)節(jié)題。從第二段最后一句“After checking the position of other Arctic landmasses,he concluded that all of them were drifting westward at different speeds.”可知答案。 答案：B 3.From the passage we can conclude that . A.Wegener liked to make things for granted B.Wegener had a true scientific attitude C.how the continents were formed is found out D.the continental drift theory needs further testing 解析：本題為推理判斷題。從文中看，Wegener的大陸漂移學(xué)說(shuō)是有科學(xué)依據(jù)的，說(shuō)明他有實(shí)事求是的科學(xué)態(tài)度，而不是想當(dāng)然。 答案：B D By the Louisiana Purchase of 1803 the United States bought from France a vast area of some 828 000 square miles.This was one of the biggest land purchases in history.The area stretches from the Mississippi River in the east to the Rocky Mountains in the west and from the Gulf of Mexico in the south to the United States—Canadian border in the north.This territory（領(lǐng)土） makes up a third of the United States.It included,before territorial adjustment,all or parts of what were to become 15 States. This huge region was explored in the 16th century by the Spaniard.A Frenchman,in 1682,named it Louisiana in honor of his king,Louis XIV（1638-1715）.Early in the 18th century the French founded settlements along the Mississippi River.The most important one,New Orleans,was founded in 1718 on the east bank of the river,90 miles from its mouth.In 1732 the French Government took control of Louisiana. At the end of the French and Indian War（1754-1763） in North America,French lost its lands east of the Mississippi to the Britain.In an agreement France gave up Louisiana—the French lands west of the Mississippi,and New Orleans—to Spain. In the late 18th century Napoleon Bonaparte（1769-1821） rose to become the first emperor of France.He dreamed of creating a new French colonial empire in North America.In 1800 he persuaded the Spanish rulers to sign the secret Treaty of San Ildefonso.This treaty transferred Louisiana back to France.On October 15,1802,the king of Spain finally gave the order transferring Louisiana to France. When President Thomas Jefferson（1743-1826） learnt of the secret agreement,he was very worried.He did not welcome the idea of having a strong France as a neighbour in the west in place of the weak Spain.Jefferson was also afraid that when the French controlled New Orleans they would close the Mississippi to America trade. Jefferson ordered Robert R.Livingston（1746-1813）,the America minister to France,to explore the possibility of purchasing New Orleans and part of West Florida near the mouth of the Mississippi.Jefferson used psychology to force Napoleon’s hand.He permitted to fall into the hands of the French Emperor some false secret letters,saying that the United States would join Britain for an attack on Louisiana.In March,1830,James Monroe（1758-1831） went to Paris,who was empowered to offer Napoleon up to $10 000 000 for New Orleans and a tract of land on the Gulf of Mexico. 本文主要記載了Louisiana歸入美國(guó)版圖的歷史演變過(guò)程。 1.What is the main idea of the text? A.The history of Louisiana. B.The purchase of a piece of land. C.The wars between different countries for Louisiana. D.The great wisdom of Thomas Jefferson in winning Louisiana for the United States. 解析：本題為主旨大意題。文章講述了Louisiana被各殖民者所購(gòu)買(mǎi)的歷史。 答案：B 2.The author is most likely to agree with which of the following statements? A.Louisiana was by far the largest state of the United States at that time. B.The name Louisiana was most commonly seen in Spain. C.France lost its control of Louisiana to Britain after losing the French
