    California is a land of variety and contrast. Almost everytype of physical land feature, sort of arctic ice fields and tropical junglescan be found within its borders. Sharply contrasting types of land often lievery close to one another. People living in Bakersfield, for instance, canvisit the Pacific Ocean and the coastal plain, the fertile San Joaquin Valley,the arid Mojave Desert, and the high Sierra Nevada, all within a radius ofabout 100 miles.

    In other areas it is possible to go snow skiing in themorning and surfing in the evening of the same day, without having to travellong distance.

    Contrast abounds in California. The highest point in theUnited States (outside Alaska) is in California, and so is the lowest point(including Alaska). Mount Whitney, 14,494 feet above sea level, is separatedfrom Death Valley, 282 feet below sea level, by a distance of only 100 miles.

    The two areas have a difference in altitude of almost three miles.California has deep, clear mountain lakes like Lake Tahoe, the deepest in thecountry, but it also has shallow, salty desert lakes. It has Lake Tulainyo,12,020 feet above sea level, and the lowest lake in the country, the SaltonSea, 236 feet below sea level. Some of its lakes, like Owens Lake in Death Valley,are not lakes at all: they are dried-up lake beds. In addition to mountains,lakes, valleys, deserts, and plateaus, California has its Pacific coastline,stretching longer than the coastlines of Oregon and Washington combined.

1. Which of the following is the lowest point in the United States?

A. Lake Tulainyo.

B. Mojave desert.

C. Death Valley.

D. The Salton Sea.

2. Where is the highest point in the United States located?

A. Lake Tahoe.

B. Sierra Nevada.

C. Mount Whitney.

D. Alaska.

3. How far away is Death Valley from Mount Whitney?

A. About 3 miles.

B. Only 100 miles.

C. 282 feet.

D. 14,494 feet.

4. Which of the following is NOT mentioned in the passage as being withina radius of about 100 miles of Bakersfield?

A. The Pacific Ocean.

B. San Joaquin Valley.

C. Mojave Desert.

D. Oregon and Washington.

5. Which statement best demonstrates that California is a land of varietyand contrast?

A. The highest lake in California is Lake Tulainyo.

B. It is possible to go surfing and snow skiing in some parts ofCalifornia without having to travel long distance.

C. Sierra Nevada, San Joaquin Valley, Mojave Desert and the Pacific Oceanall lie within a radius of about 100 miles.

D. Owens Lake, in Death Valley, is not really a lake at all. 

1. C) 这是一道细节题。根据第三段所给的海拔高度,可知美国最低点在death valley。

2. D) 此题很容易误选为C,这是因为第三段提到Mount Whitney的海拔高度;但是要注意此段第二句提到美国最高点时在括号中补充说明这个最高点是在Alaska以外的。这就说明美国的海拔最高点不是Mount Whitney,而是位于Alaska。

3. B) 这是一道细节题。根据第三段可找出答案。

4. D) 根据第二段可知答案。

5. C) 文中说加利福尼亚是一个地貌多样,富于变化的地方,而选项C是一个最突出的例子



    Most earthquakes occur within the upper 15 miles of theearth's surface. But earthquakes can and do occur at all depths to about 460miles. Their number decreases as the depth increases. At about 460 miles oneearthquake occurs only every few years. Near the surface earthquakes may run ashigh as 100 in a month, but the yearly average does not vary much. Incomparison with the total number of earthquakes each year, the number ofdisastrous earthquakes is very small.

    The extent of the disaster in an earthquake depends on manyfactors. If you carefully build a toy house with an erect set, it will stillstand no matter how much you shake the table. But if you build a toy house witha pack of cards, a slight shake of the table will make it fall. An earthquakein Agadir, Morocco, was not strong enough to be recorded on distantinstruments, but it completely destroyed the city. Many stronger earthquakeshave done comparatively little damage. If a building is well constructed andbuilt on solid ground, it will resist an earthquake. Most deaths in earthquakeshave been due to faulty building construction or poor building sites. A thirdand very serious factor is panic. When people rush out into narrow streets,more deaths will result.

    The United Nations has played an important part in reducingthe damage done by earthquakes. It has sent a team of experts to all countriesknown to be affected by earthquakes. Working with local geologists and engineers,the experts have studied the nature of the ground and the type of mostpractical building code for the local area. If followed, these suggestions willmake disastrous earthquakes almost a thing of the past.

There is one type of earthquake disaster that little can be done about.This is the disaster caused by seismic sea waves, or tsunamis. (These are oftencalled tidal waves, but the name is incorrect. They have nothing to do withtides.) In certain areas, earthquakes take place beneath the sea. Thesesubmarine earthquakes sometimes give rise to seismic sea waves. The waves arenot noticeable out at sea because of their long wave length. But when they rollinto harbors, they pile up into walls of water 6 to 60 feet high. The Japanesecall them "tsunamis", meaning "harbor waves", because theyreach a sizable height only in harbors.

    Tsunamis travel fairly slowly, at speeds up to 500 miles anhour. An adequate warning system is in use to warn all shores likely to bereached by the waves. But this only enables people to leave the threatenedshores for higher ground. There is no way to stop the oncoming wave.

1. Which of the following CANNOT be concluded from the passage?

A. The number of earthquakes is closely related to depth.

B. Roughly the same number of earthquakes occur each year.

C. Earthquakes are impossible at depths over 460 miles.

D. Earthquakes are most likely to occur near the surfaces.

2. The destruction of Agadir is an example of ______.  

A. faulty building construction

B. an earthquake's strength

C. widespread panic in earthquakes

D. ineffective instruments

3. The United Nations' experts are supposed to______.

A. construct strong buildings

B. put forward proposals

C. detect disastrous earthquakes

D. monitor earthquakes

4. The significance of the slow speed of tsunamis is that peoplemay______.

A. notice them out at sea

B. find ways to stop them

C. be warned early enough

D. develop warning systems

    I live in the land of Disney, Hollywood and year-round sun.You may think people in such a glamorous, fun-filled place are happier thanothers. If so, you have some mistaken ideas about the nature of happiness.

    Many intelligent people still equate happiness with fun. Thetruth is that fun and happiness have little or nothing in common. Fun is whatwe experience during an act. Happiness is what we experience after an act. Itis a deeper, more abiding emotion.

    Going to an amusement park or ball game, watching a movie ortelevision, are fun activities that help us relax, temporarily forget ourproblems and maybe even laugh. But they do not bring happiness, because theirpositive effects end when the fun ends.

    I have often thought that if Hollywood stars have a role toplay, it is to teach us that happiness has nothing to do with fun. These rich,beautiful individuals have constant access to glamorous parties, fancy cars,expensive homes, everything that spells “happiness”. But in memoir aftermemoir, celebrities reveal the unhappiness hidden beneath all their fun:depression, alcoholism, drug addiction, broken marriages, troubled children andprofound loneliness.

    Ask a bachelor why he resists marriage even though he findsdating to be less and less satisfying. If he’s honest, he will tell you that heis afraid of making a commitment. For commitment is in fact quite painful. Thesingle life is filled with fun, adventure and excitement. Marriage has suchmoments, but they are not its most distinguishing features.

    Similarly, couples that choose not to have children aredeciding in favor of painless fun over painful happiness. They can dine outever they want and sleep as late as they want. Couples with infant children arelucky to get a whole night’s sleep or a three-day vacation. I don’t know anyparent who would choose the word fun to describe raising children.

    Understanding and accepting that true happiness has nothingto do with fun is one of the most liberating realizations we can ever come to.It liberates time: now we can devote more hours to activities that cangenuinely increase our happiness. It liberates money: buying that new car orthose fancy clothes that will do nothing to increase our happiness now seemspointless. And it liberates us from envy: we now understand that all those richand glamorous people we were so sure are happy because they are always havingso much fun actually may not be happy at all.

1.Which of the following is true?

A. Fun creates long-lasting satisfaction.

B. Fun provides enjoyment while pain leads to happiness.

C. Happiness is enduring whereas fun is short-lived.

D. Fun that is long-standing may lead to happiness.

2.To the author, Hollywood stars all have an important role to play thatis to __.

A. rite memoir after memoir about their happiness.

B. tell the public that happiness has nothing to do with fun.

C. teach people how to enjoy their lives.

D. bring happiness to the public instead of going to glamorous parties.

3.In the author’s opinion, marriage___.

A. affords greater fun.

B. leads to raising children.

C. indicates commitment.

D. ends in pain.

4.Couples having infant children___.

A. are lucky since they can have a whole night’s sleep.

B. find fun in tucking them into bed at night.

C. find more time to play and joke with them.

D. derive happiness from their endeavor.

5.If one get the meaning of the true sense of happiness, he will__.

A. stop playing games and joking with others.

B. make the best use of his time increasing happiness.

C. give a free hand to money.

D. keep himself with his family.

    Once it was possible to define male and female roles easilyby the division of labor. Men worked outside the home and earned the income tosupport their families, while women cooked the meals and took care of the homeand the children. These roles were firmly fixed for most people, and there wasnot much opportunity for women to exchange their roles. But by the middle ofthis century, men’s and women’s roles were becoming less firmly fixed.

   In the 1950s, economic and social success was the goal of thetypical American. But in the 1960s a new force developed called thecounterculture. The people involved in this movement did not value themiddle-class American goals. The counterculture presented men and women withnew role choices. Taking more interest in childcare, men began to sharechild-raising tasks with their wives. In fact, some young men and women movedto communal homes or farms where the economic and childcare responsibilitieswere shared equally by both sexes. In addition, many Americans did not valuethe traditional male role of soldier. Some young men refused to be drafted assoldiers to fight in the war in Vietnam.

    In terms of numbers, the counterculture was not a very largegroup of people. But its influence spread to many parts of American society.Working men of all classes began to change their economic and social patterns.Industrial workers and business executives alike cut down on “overtime” work sothat they could spend more leisure time with their families. Some doctors,lawyers, and teachers turned away from high paying situations to practice theirprofessions in poorer neighborhoods.

    In the 1970s, the feminist movement, or women’s liberation,produced additional economic and social changes. Women of all ages and at alllevels of society were entering the work force in greater numbers. Most of themstill took traditional women’s jobs as public school teaching, nursing, andsecretarial work. But some women began to enter traditionally male occupations:police work, banking, dentistry, and construction work. Women were asking forequal work, and equal opportunities for promotion.

    Today the experts generally agree that important changes aretaking place in the roles of men and women. Naturally, there are difficultiesin adjusting to these transformations.

1.Which of the following best express the main idea of Paragraph 1?

A. Women usually worked outside the home for wages.

B. Men and women’s roles were easily exchanged in the past.

C. Men’s roles at home were more firmly fixed than women’s.

D. Men and women’s roles were usually quite separated in the past.

2.Which sentence best expresses the main idea of Paragraph 2?

A. The first sentence.

B. The second and the third sentences.

C. The fourth sentence.

D. The last sentence.

3.In the passage the author proposes that the counterculture___.

A. destroyed the United States.

B. transformed some American values.

C. was not important in the United States.

D. brought people more leisure time with their families.

4.It could be inferred from the passage that___.

A. men and women will never share the same goals.

B. some men will be willing to exchange their traditional male roles.

C. most men will be happy to share some of the household responsibilitieswith their wives.

D. more American households are headed by women than ever before.

5.The best title for the passage may be ___.

A. Results of Feminist Movements

B. New influence in American Life

C. Counterculture and Its consequence

D. Traditional Division of Male and Female Roles.


参考答案 1~5:DCBCB



    Recent research has claimed that an excess of positive ionsin the air can have an ill effect on people’s physical or psychological health.What are positive ions? Well, the air is full of ions, electrically chargedparticles, and generally there is a rough balance between the positive and thenegative charged. But sometimes this balance becomes disturbed and a largerproportion of positive ions are found. This happens naturally beforethunderstorm, earthquakes when winds such as the Mistral, Hamsin or Sharav areblowing in certain countries. Or it can be caused by a build-up of staticelectricity indoors from carpets or clothing made of man-made fibres, or fromTV sets, duplicators or computer display screens.

    When a large number of positive ions are present in the airmany people experience unpleasant effects such as headaches, fatigue,irritability, and some particularly sensitive people suffer nausea or evenmental disturbance. Animals are also affected, particularly before earthquakes,snakes have been observed to come out of hibernation, rats to flee from theirburrows, dogs howl and cats jump about unaccountably. This has led the USGeographical Survey to fund a network of volunteers to watch animals in aneffort to foresee such disasters before they hit vulnerable areas such asCalifornia.

    Conversely, when large numbers of negative ions are present,then people have a feeling of well-being. Natural conditions that produce theselarge amounts are near the sea, close to waterfalls or fountains, or in anyplace where water is sprayed, or forms a spray. This probably accounts for thebeneficial effect of a holiday by the sea, or in the mountains with tumblingstreams or waterfalls.

    To increase the supply of negative ions indoors, somescientists recommend the use of ionisers: small portable machines, whichgenerate negative ions. They claim that ionisers not only clean and refresh theair but also improve the health of people sensitive to excess positive ions. Ofcourse, there are the detractors, other scientists, who dismiss such claims andare skeptical about negative/positive ion research. Therefore people can onlymake up their own minds by observing the effects on themselves, or on others,of a negative rich or poor environment. After all it is debatable whetherdepending on seismic readings to anticipate earthquakes is more effective thanwatching the cat.

1.What effect does exceeding positive ionization have on some people?

A. They think they are insane.

B. They feel rather bad-tempered and short-fussed.

C. They become violently sick.

D. They are too tired to do anything.

2.In accordance with the passage, static electricity can be caused by___.

A. using home-made electrical goods.

B. wearing clothes made of natural materials.

C. walking on artificial floor coverings.

D. copying TV programs on a computer.     

3.A high negative ion count is likely to be found___.

A. near a pound with a water pump.

B. close to a slow-flowing river.

C. high in some barren mountains.

D.by a rotating water sprinkler.

4.What kind of machine can generate negative ions indoors?

A. Ionisers.

B. Air-conditioners.

C. Exhaust-fans

D. Vacuum pumps.

5.Some scientists believe that___.

A. watching animals to anticipate earthquakes is more effective thandepending on seismography.

B. the unusual behavior of animals cannot be trusted.

C. neither watching nor using seismographs is reliable.

D. earthquake

    A study of art history might be a good way to learn moreabout a culture than is possible to learn in general history classes. Mosttypical history courses concentrate on politics, economics, and war. But arthistory focuses on much more than this because art reflects not only the politicalvalues of a people, but also religious beliefs, emotions, and psychology. Inaddition, information about the daily activities of our ancestors—or of peoplevery different from our own—can be provided by art. In short, art expresses theessential qualities of a time and a place, and a study of it clearly offer us adeeper understanding than can be found in most history books.

    In history books, objective information about the politicallife of a country is presented; that is, facts about politics are given, butopinions are not expressed. Art, on the other hand, is subjective: it reflectsemotions and opinions. The great Spanish painter Francisco Goya was perhaps thefirst truly “political” artist. In his well-known painting The Third of May1808, he criticized the Spanish government for its misuse of power over people.Over a hundred years later, symbolic images were used in Pablo Picasso’sGuernica to express the horror of war. Meanwhile, on another continent, thepowerful paintings of Diego Rivera, Jose Clemente Orozco, and David AlfaroSiqueiros—as well as the works of Alfredo Ramos Martines—depicted these Mexicanartists’ deep anger and sadness about social problems.

    In the same way, art can reflect a culture’s religiousbeliefs. For hundreds of years in Europe, religious art was almost the onlytype of art that existed. Churches and other religious buildings were filledwith paintings that depicted people and stories from the Bible. Although mostpeople couldn’t read, they could still understand biblical stories in thepictures on church walls. By contrast, one of the main characteristics of artin the Middle East was (and still is) its absence of human and animal images.This reflects the Islamic belief that statues are unholy.

1.More can be learned about a culture from a study of art history thangeneral history because art history____.

A. show us the religious and emotions of a people in addition to politicalvalues.

B. provide us with information about the daily activities of people in thepast.

C. give us an insight into the essential qualities of a time and a place.

D. all of the above.

2.Art is subjective in that__.

A. a personal and emotional view of history is presented through it.

B.it can easily rouse our anger or sadness about social problems.

C.it will find a ready echo in our hearts.

D. both B and C.

3.Which of the following statements is true according to the passage?

A. Unlike Francisco Goya, Pablo and several Mexican artists expressedtheir political opinions in their paintings.

B. History books often reveal the compilers’ political views.

C. Religious art remained in Europe for centuries the only type of artbecause most people regarded the Bible as the Holy Book.

D. All the above mentioned.

4.The passage is mainly discussing___.

A. the difference between general history and art history.

B. The making of art history.

C. What can we learn from art.

D. The influence of artists on art history.

5.In may be concluded from this passage that___.

A. Islamic artists have had to create architectural decorations withimages of flowers or geometric forms.

B. History teachers are more objective than general history.

C. It is more difficult to study art history than general history.

D. People and stories from the Bible were painted on churches and otherbuildings in order to popularize the Bible.


参考答案:1~5 DDDCA



    If the old maxim that the customer is always right still hasmeaning, then the airlines that ply the world’s busiest air route betweenLondon and Paris have a flight on their hands.

    The Eurostar train service linking the UK and Frenchcapitals via the Channel Tunnel is winning customers in increasing numbers. Inlate May, it carried its one millionth passenger, having run only a limitedservice between London, Paris and Brussels since November 1994, starting withtwo trains a day in each direction to Paris and Brussels. By 1997, the companybelieves that it will be carrying ten million passengers a year, and continueto grow from there.

    From July, Eurostar steps its service to nine trains eachway between London and Paris, and five between London and Brussels. Each traincarries almost 800 passengers, 210 of them in first class.

    The airlines estimate that they will initially lose around15%-20% of their London-Paris traffic to the railways once Eurostar starts afull service later this year (1995), with 15 trains a day each way. A similarservice will start to Brussels. The damage will be limited, however, theairlines believe, with passenger numbers returning to previous levels withintwo to three years.

     In the short term, the damage caused by the 1 millionpeople-levels traveling between London and Paris and Brussels on Eurostartrains means that some air services are already suffering. Some of the majorcarriers say that their passenger numbers are down by less than 5% and point totheir rivals-Particularly Air France-as having suffered the problems. On theBrussels route, the railway company had less success, and the airlines reportanything from around a 5% drop to no visible decline in traffic.

    The airlines' optimism on returning traffic levels is basedon historical precedent. British Midland, for example, points to its experienceon Heathrow Leeds Bradford service which saw passenger numbers fold by 15% whenBritish Rail electrified and modernized the railway line between London andYorkshire. Two years later, travel had risen between the two destinations tothe point where the airline was carrying record numbers of passengers.

1.British airlines confide in the fact that__.

A. they are more powerful than other European airlines.

B. their total loss won’t go beyond a drop of 5% passengers.

C. their traffic levels will return in 2-3 years.

D. traveling by rail can never catch up with traveling by air.

2.The author’s attitude towards the drop of passengers may be describedas__.

A. worried.

B. delighted

C. puzzled.

D. unrivaled.

3.In the passage, British Rail (Para 6) is mentioned to__.

A. provide a comparison with Eurostar.

B. support the airlines’ optimism.

C. prove the inevitable drop of air passengers.

D. call for electrification and modernization of the railway.

4.The railway’s Brussels route is brought forth to show that__.

A. the Eurostar train service is not doing good business.

B. the airlines can well compete with the railway.

C. the Eurostar train service only caused little damage.

D. only some airlines, such as Air France, are suffering.

5.The passage is taken from the first of an essay, from which we may wellpredict that in the following part the author is going to__.

A. praise the airlines’ clear-mindedness.

B. warn the airlines of high-speed rail services.

C. propose a reduction of London/Paris flights.

D. advise the airlines to follow British Midland as their model.


参考答案:1~5 CABCB



    Without regular supplies of some hormones our capacity tobehave would be seriously impaired; without others we would soon die. Tinyamounts of some hormones can modify moods and actions, our inclination to eator drink, our aggressiveness or submissiveness, and our reproductive andparental behavior. And hormones do more than influence adult behavior; early inlife they help to determine the development of bodily form and may evendetermine an individual’s behavioral capacities. Later in life the changingoutputs of some endocrine glands and the body’s changing sensitivity to somehormones are essential aspects of the phenomena of aging.

    Communication within the body and the consequent integrationof behavior were considered the exclusive province of the nervous system up tothe beginning of the present century. The emergence of endocrinology as aseparate discipline can probably be traced to the experiments of Bayliss andStarling on the hormone secretion. This substance is secreted from cells in theintestinal walls when food enters the stomach; it travels through thebloodstream and stimulates the pancreas to liberate pancreatic juice, whichaids in digestion. By showing that special cells secret chemical agents thatare conveyed by the bloodstream and regulate distant target organs or tissues.Bayliss and starling demonstrated that chemical integration could occur withoutparticipation of the nervous system.

    The term “hormone” was first used with reference tosecretion. Starling derived the term from the Greek hormone, meaning “to exciteor set in motion. The term “endocrine” was introduced shortly thereafter“Endocrine” is used to refer to glands that secret products into thebloodstream. The term “endocrine” contrasts with “exocrine”, which is appliedto glands that secret their products though ducts to the site of action.Examples of exocrine glands are the tear glands, the sweat glands, and thepancreas, which secrets pancreatic juice through a duct into the intestine.Exocrine glands are also called duct glands, while endocrine glands are calledductless.

1.What is the author’s main purpose in the passage?

A. To explain the specific functions of various hormones.

B. To provide general information about hormones.

C. To explain how the term “hormone” evolved.

D. To report on experiments in endocrinology.

2.The passage supports which of the following conclusions?

A. The human body requires large amounts of most hormones.

B. Synthetic hormones can replace a person’s natural supply of hormones ifnecessary.

C. The quantity of hormones produced and their effects on the body arerelated to a person’s age.

D. The short child of tall parents very likely had a hormone deficiencyearly in life.

3.It can be inferred from the passage that before the Bayliss and Starlingexperiments, most people believed that chemical integration occurred only___.

A. during sleep.

B. in the endocrine glands.

C. under control of the nervous system.

D. during strenuous exercise.

4.The word “liberate” could best be replaced by which of the following?

A. Emancipate

B. Discharge

C. Surrender

D. Save

5.According to the passage another term for exocrine glands is___.

A. duct glands

B. endocrine glands

C. ductless glands

D. intestinal glands.

    The discovery of the Antarctic not only proved one of themost interesting of all geographical adventures, but created what might becalled “the heroic age of Antarctic exploration”. By their tremendous heroism,men such as Shakleton, Scott, and Amundsen caused a new continent to emergefrom the shadows, and yet that heroic age, little more than a century old, isalready passing. Modern science and inventions are revolutionizing theendurence, future journeys into these icy wastes will probably depend on motorvehicles equipped with caterpillar traction rather than on the dogs thatearlier discoverers found so invaluable and hardly comparable.

    Few realize that this Antarctic continent is almost equal insize to South America, and enormous field of work awaits geographers andprospectors. The coasts of this continent remain to be accurately charted, andthe mapping of the whole of the interior presents a formidable task to thecartographers who undertake the work. Once their labors are completed, it willbe possible to prospect the vast natural resources which scientists believewill furnish one of the largest treasure hoards of metals and minerals theworld has yet known, and almost inexhaustible sources of copper, coal, uranium,and many other ores will become available to man. Such discoveries will usherin an era of practical exploitation of the Antarctic wastes.

    The polar darkness which hides this continent for the sixwinter months will be defeated by huge batteries of light, and make possiblethe establishing of air-fields for the future inter-continental air services bymaking these areas as light as day. Present flying routes will be completelychanged, for the Antarctic refueling bases will make flights from Australia toSouth America comparatively easy over the 5,000 miles journey.

    The climate is not likely to offer an insuperable problem,for the explorer Admiral Byrd has shown that the climate is possible even formen completely untrained for expeditions into those frozen wastes. Some of hisparties were men who had never seen snow before, and yet he records that theysurvived the rigors of the Antarctic climate comfortably, so that, providedthat the appropriate installations are made, we may assume that human beingsfrom all countries could live there safely. Byrd even affirms that it isprobably the most healthy climate in the world, for the intense cold ofthousands of years has sterilize this continent, and rendered it absolutely germfree,with the consequences that ordinary and extraordinary sickness and diseasesfrom which man suffers in other zones with different climates are here utterlyunknown. There exist no problems of conservation and preservation of foodsupplies, for the latter keep indefinitely without any signs of deterioration;it may even be that later generations will come to regard the Antarctic as thenatural storehouse for the whole world.

    Plans are already on foot to set up permanent bases on theshores of this continent, and what so few years ago was regarded as a “deadcontinent” now promises to be a most active center of human life and endeavor.

1.When did man begin to explore the Antarctic?

A. About 100years ago.

B. In this century.

C. At the beginning of the 19th century.

D. In 1798.

2.What must the explorers be, even though they have modern equipment andtechniques?

A. Brave and tough

B. Stubborn and arrogant.

C. Well-liked and humorous.

D. Stout and smart.

3.The most healthy climate in the world is___.

A. in South America.

B. in the Arctic Region.

C. in the Antarctic Continent.

D. in the Atlantic Ocean.

4.What kind of metals and minerals can we find in the Antarctic?

A. Magnetite, coal and ores.

B. Copper, coal and uranium.

C. Silver, natural gas and uranium.

D. Aluminum, copper and natural gas.

5.What is planned for the continent?

A. Building dams along the coasts.

B. Setting up several summer resorts along the coasts.

C. Mapping the coast and whole territory.

D. Setting up permanent bases on the coasts.

    Nearly everyone agrees that money doesn’t buy as much as itused to, no matter where you want to spend it. This is certainly true of thepaper money that passes so quickly through one‘s hands. Inflation(通货膨胀) eats away at its buying power just as the steadyappetite of waves chews at sand cliffs. But what about coins that seem to dovery little except wear out your purses and pockets? Unlike notes, metal money becomes more valuable thelonger it is held, especially if it is put away where it won’t get scratched orworn. Why is this? One reason is thatcoins, being more durable, fall more readily into a category for collectors.Naturally, the rarer gold pieces must become more valuable as the price of thismetal goes up.

    But, curiously, one of the rarest coins in the world is notmade of gold, but of the relatively cheaper silver. In 1804, the United Statesmint(造币厂) struck 19,570 silver dollars. That is what itsrecords show. Today only six of this original number remain and these areunlikely ever to reach the auction market. So what happened to some 19,564large silver coins, not the easiest sort of things to lose? One of the more romantic theories is that they were partof the payment to Napoleon for the American territory then known as Louisiana.But they never reached France. Somewhere in the Gulf of Mexico, the shiptransporting them was sunk, either by a storm or by pirates. The probableanswer to the mystery is that they were melted down—since the silver value wasgreater than the actual value of the coin. What really happened to the restwill probably always remain a mystery. What is known is that whoever can comeup with one will find himself instantly rich.

26. It can be inferred from passage that_______.

A. money buys as much as it did before

B. money does not buy as much as it did before

C. paper money buys more than metal money

D. metal money buys more than paper money

27. Which of the following is TRUE of a coin?

A. The longer it is held, the less valuable it becomes.

B. The more it wears out, the more valuable it becomes.

C. The less it gets scratched, the less it values.

D. The longer it lasts, the more it values.

28. According to this passage, one of the rarest coins in the world ismade of 

A. silver   B. gold   C. copper   D. paper

29. Coins become more valuable because_______.

A. they wear out your purses and pockets

B. the price of metal goes up
