No other colonial artisans rivaled thesilversmiths’ prestige. They handled the mostexpensive materials and possessed direct connections to prosperous colonial merchants. Theirproducts, primarily silver plates and bowls, reflected their exalted status and testified to theircustomers’ prominence. Silver stood as one of the surest ways to store wealth at a time beforeneighborhood banks existed. Unlike the silver coins from which they were made, silver articleswere readily identifiable. Often formed to individual specifications, they always carried thesilversmith’s distinctive markings and consequently could be traced and retrieved.Customers generally secure the silver for the silver object they ordered. They saved coins, tookthem to smiths, and discussed the type of pieces they desired. Silversmiths complied with theserequests by melting the money in a small furnace, adding a bit of copper to form a strongeralloy, and casting the alloy in rectangular blocks. They hammered these ingots to theappropriate thickness by hand, shaped them and pressed designs into them for adornment.Engraving was alsodone by hand. In addition to plates and bowls, some customers soughtmore intricate products, such as silver teapots. These were made by shaping or casting partsseparately and then soldering them together. Colonial coppersmithing also come of age in theearly eighteenth century and prospered in northern cities. Copper’s ability to conduct heatefficiently and to resist corrosion contributed to its attractiveness. But because it wasexpensive in colonial America, coppersmiths were never very numerous. Virtually all copperworked by Smiths was imported as sheets or obtained by recycling old copper goods. Copperwas used for practical items, but it was not admired for its beauty. Coppersmiths employed it tofashion pots and kettles for the home. They shaped it in much the same manner as silver ormelted it in a foundry with lead or tin. They also mixed it with zinc to make brass for maritimeand scientific instruments.?1、According to the passage, which of the following eighteenth century developments had strongimpact on silversmithsA. A decrease in the cost of silver.B. The invention of heat efficient furnaces.C. The growing economic prosperity of colonial merchants.D. The development of new tools used to shape silver.2.In colonial America, where did silversmiths usually obtain the material to make silver articles? ?A. From their own mines.B. From importers.C. From other silversmiths.D. From customers.3.The passage mentions all of the following as uses for copper in Colonial America EXCEPT ______A. cooking potsB. scientific instrumentsC. musical instrumentsD. maritime instruments4.According to the passage, silversmiths and coppersmiths in colonial America were similar inwhich of the following waysA. The amount of social prestige they had.B. The way they shaped the metal they worked with. ?C. The cost of the goods they made.D. The practicality of the goods they made.参考答案：1. C) 根据文章第一句“As the merchant classexpanded in the eighteenth?century North AmericanColonies,...”可知，随着在十八世纪的北美殖民地商人阶级膨胀起来，也就是说那时的商人财富有了很大的发展，银匠铜匠们有机会发挥他们的.专长了，这与选项C正好相符。

For each question, there are four suggested answers marked [A], [B], [C] and [D]. Choose the one that you think is the best answer.__________________________________________________________________________________________ 解析：We're always being told by the Department of Health to eat five portions of fruit and vegetables a day. But it's not clear where the evidence for this comes from and a large study by the European Prospective Investigation into Cancer and Nutrition(EPIC)two years ago of the dietary intake of more than 400, 000 people found only a weak link between eating fruit and vegetables and a reduction in overall cancer risk. There's no evidence it reduces breast or prostate cancer. Even so, how could anyone argue against eating more fruit and vegetables? Well, it depends what fruit you're eating. A review article in the Canadian Medical Association Journal warns that a chemical in grapefruits can interact fatally with certain medicines. Even apple juice, the staple of many breakfast tables, may reduce our absorption of some drugs. Parents also often think fruit juice is a healthy alternative to soda drinks but juices contain sugar and calories too—as much as a glass of Coke(160 calories)—so should be drunk in moderation. Grapefruit has also been linked to an increase in breast cancer. A study in the British Journal of Cancer(BJC)of 500, 000 postmenopausal women found that eating a quarter of the fruit a day increased the risk by 30%. There is one good reason for not eating grapefruits—they taste sour. But they are unlikely to increase your risk of breast cancer: further research in the BJC showed no increase of breast cancer in pre- or post-menopausal women who tuck into grapefruits or drink juice. Grapefruit contains a type of chemical called furanocoumarin(also found in Seville oranges and limes but not Valencia or other sweet oranges), which, by inhibiting the enzyme CYP3A4, stops the breakdown of some prescription drugs. So the concentrations of these drugs rise and can have serious side-effects, including kidney damage, heart block(where no electrical impulses pass through the heart and it can stop beating), and deep vein thrombosis(which occurred when an oral contraceptive was taken by a woman who also ate grapefruit three days in a row). Patient information leaflets should tell you what foods to avoid with which drugs. If in doubt, ask your doctor. So you don't need to eat less fruit, and may still need to eat more. Another paper from the EPIC study found a 22% reduction in deaths from heart attacks in people who ate eight portions of fruit and vegetables a day compared to those who ate three or fewer. The way the study is designed, however, means that it can only suggest a link—it can't prove one.（分数：6.00）(1).EPIC conducted a research two years ago to______.（分数：2.00）A.prove that people should eat five portions of fruit a dayB.find a way to reduce the overall cancer riskC.make sure the right amount of fruit eaten every dayD.investigate the relation between eating fruit and reducing cancer risk √解析：解析：推理题。

专业英语四级（阅读）模拟试卷138(题后含答案及解析)题型有：1. 2.SECTION AIn this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked [A], [B], [C] and [D]. Choose the one that you think is the best answer.(1)Climbing to the top of my nearest hill in San Francisco, my purpose is not to enjoy the view but to experience a bit of fresh air and nature. Some birds dwell in these urban islands of trees, bushes and soil. So few people are there, but they are happy, relaxed and friendly(unless insane and out to rob). I find the view of San Francisco Bay and the metropolis most disturbing, seeing in all directions the industrial activity and oil-fueled trade of questionable imported products. Massive port facilities dwarf the human scale of sustainable import/export. A very small number of sailboats for pleasure can’t quite offer a vision of renewable-energy travel and exchange. Passenger planes take off, military jets show off their ear-splitting capabilities, all against the backdrop of polluted air that is warming in general thanks to commercial activity and the mindless consumption by the individual. The hills are full of roads and energy-wasting houses. It’s not like this everywhere; the hills around Kyoto are pitch black at night, for they consist of forest, trails and small, outdoor temples. (2)Seven million people surround me in this metropolitan area. Those among them who really care whether Barry Bonds used steroids to hit baseballs, or what pregnant celebrity has checked into a drug rehabilitation facility, are not likely to be trying to live lightly on the planet. Normal citizens under the spell of mass media want to consume, and be given answers and easy fixes. They may get what they want tonight, and a-gain, and again, but it will come to an abrupt end, and will people pick up a shovel to plant food or pick up the gun to take others’ food? That depends on the area affected, the culture(urban U.S. or otherwise), and population size. (3)Why should I be disturbed by what I see now, when all is basically calm? Or feel uneasy as I stroll about in the safety of my comfortable home? Is not San Francisco and the surrounding area a great city, with many wonderful people and activities to appreciate? What about the noble struggles of valiant, compromised hard-working people, or the dysfunctional and disabled folk who are really kind? The social injustice that is still pervasive, in our boastful age of scientific and technological power, is outrageous and occupies many of the best hearts and minds in the world who live in our very midst. Much of what ails people, it is thought, is that they do not have enough cheap, affordable energy or material things that are supposed to both satisfy and uplift. More public funds for health care, through an end to costly, imperialist wars, would be the ticket to a healthy society, in the eyes of more and more. (4)Except, that selfless aspiration is becoming clouded with the uncertainty and fright growing around our awakening to climate change. In the buzzing Bay Area and every other large and small city, we are behaving as if there is no threat to the climate and thus our futuresurvival as a species. Just looking around at the unceasing traffic, it is clear that basic, radical but easy solutions are being kept on the shelf or buried. Tiny changes, usually just initiatives that don’t threaten the current life style(e.g., different engines), are called “green”. Green this and green that. But the big “greening”will be the rediscovery of community and working with others as if our survival depends on our collaboration as equals. Our bosses and political leaders have been as useful in the needed transition as—to borrow an expression from my late father—tits on a bull.1．What do the “few people” do on top of the hill?A．They are the rich residents of the city.B．They are there to enjoy the natural beauty.C．They are attracted by the view of San Francisco Bay.D．They attack the tourists and rob them.正确答案：B解析：根据第1段第3句的happy，relaxed and friendly及第1、2句的内容可以推断这few people和作者一样上山是为了呼吸新鲜空气和亲近自然的，由此看来，B与原文内容最接近，选B。

专业英语四级（阅读）模拟试卷142(题后含答案及解析)题型有：1. 2.SECTION AIn this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked [A], [B], [C] and [D]. Choose the one that you think is the best answer.(1)Spanning the ocean divide between the U.S. and Russia, it is one of the richest and most commercially productive marine environments on earth, teeming with pollack and halibut, fur seals and Steller’s sea lions, puffins and murres. The seals and seabirds depend on catching fish, and so do humans. More than 2,000 boats from the U.S., Russia, Japan, Norway, China, Poland and the Koreas haul in an annual catch worth roughly $1 billion. The portion taken off the shores of Alaska alone amounts to one-half the sea life caught by commercial fishing vessels in U.S. waters.(2)But will the bounty last? Since the majority of the world’s fisheries are in a state of collapse, as too many boats chase too few fish, conservationists fear the same fate for the Bering Sea, the last great refuge of marine abundance. Competition among countries for the rights to fish certain sectors of the sea is already fierce and could turn violent, as it has elsewhere in the world. The Russians have severely depleted fish stocks in their zone, and the international area open to all boats, called the Doughnut Hole, has been nearly stripped of commercial fish. (3)No species is more important to man and beast than pollack, the No. 1 ingredient of frozen fish sticks and the fish items served by chains like Burger King and Long John Silver. Each year the Bering Sea yields two billion kg of this bottom-dwelling creature, making the pollack business the biggest fish harvest in the world. (4)On the surface, that business is healthy: the pollack catch has stayed near record levels. But signs of overfishing and an ailing ecosystem can be seen higher up in the food chain. The fur-seal population has not increased despite a long-standing ban on commercial hunting. The number of Steller’s sea lions, which feed mostly on pollack, has plunged 80% in the past years, and seabirds such as the red-legged kittiwake are also in trouble. (5)The pollack harvest may be huge, but that doesn’t mean the fish is still abundant everywhere. If commercial fishermen overfish a spot near nursing sea lions, both mothers and pups can starve. That’s why the Trustees for Alaska, a public interest law firm, has sued the U.S. government for failing to protect areas vital to endangered marine mammals. The group’s litigation director, Peter Van Tuyn, points out that in southeast Alaskan waters, where there is little industrial fishing of pollack, the sea lion population has held up relatively well. And fur seals in the Pribilofs have done better than sea lions, perhaps because they have a more varied diet. (6)Less fortunate are other creatures that get in the fishermen’s way. Dorothy Childers, executive director of the Alaska Marine Conservation Council, notes that fishing boats aiming to catch pollack dump halibut and salmon over the side and that the value of wasted fish in the Bering Sea is equivalent to 25% of the revenues from the entire fishery. Many trawlers drag netsand other gear across the sea floor, destroying the habitat of all the animals that live on the bottom. International agreements restrict the size of fishing nets, but environmental groups like the World Wildlife Fund urge stronger action: enforcing a new agreement to stop bottom trawling for pollack, reducing the pressure on certain areas and putting critical habitats off limits. (7)Even if fishing is brought under control, the Bering Sea faces threats that originate thousands of miles away. Wind currents from industrial areas far to the south bring in pollutants like insecticides and heavy metals, which collect in the tissues of wild life and the local Inuit people. At the same time the region has been warming up, and part of the reason may be the buildup of greenhouse gases in the atmosphere. Whatever the cause, sea ice has been retreating farther to the north, making life harder for polar bears and other ice-dwelling animals.1．What is true about the marine creatures in the Bering Sea?A．Russia tries to save the sea by stocking fewer fish.B．There are still abundant marine creatures there.C．It will soon be stripped of commercial fish.D．There are too many boats but too few fish.正确答案：B解析：根据题干中的Bering Sea定位到第2段第2句。

英语专业四级考试阅读理解Passage 1Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind. These passions, like great winds, have blown me hither and thither, in a wayward course, over a great ocean of anguish, reaching to the very verge of despair.I have sought love, first, because it brings ecstasy - ecstasy so great that I would often have sacrificed all the rest of life for a few hours of this joy. I have sought it, next, because it relieves loneliness--that terrible loneliness in which one shivering consciousness looks over the rim of the world into the cold unfathomable lifeless abyss. I have sought it finally, because in the union of love I have seen, in a mystic miniature, the prefiguring vision of the heaven that saints and poets have imagined. This is what I sought, and though it might seem too good for human life, this is what--at last--I have found.With equal passion I have sought knowledge. I have wished to understand the hearts of men. I have wished to know why the stars shine. And I have tried to apprehend the Pythagorean power by which number holds sway above the flux. A little of this, but not much, I have achieved.Love and knowledge, so far as they were possible, led upward toward the heavens. But always pity brought me back to earth. Echoes of cries of pain reverberate in my heart. Children in famine, victims tortured by oppressors, helpless old people a burden to their sons, and the whole world of loneliness, poverty, and pain make a mockery of what human life should be. I long toalleviate this evil, but I cannot, and I too suffer.This has been my life. I have found it worth living, and would gladly live it again if the chance were offered me.1. In the first paragraph, Russel says that _________.A. he has travelled over a great ocean for the three passions.B. the result of his search is despair.C. he longs for love and never despairs.D. he has pity for the suffering of mankind and often feels anguish.2. In the second paragraph, Russel thinks that he has found in his search for love all the following except _______.A. happinessB. the vision of the hellC. solitudeD. relief from loneliness3. Whenever Russel thinks of the suffering of mankind, he _______.A. feels humiliatedB. becomes overjoyedC. feels he will be embraced by GodD. feels anguish and suffers too.4. In line 3, “hither and thither”meansA. everywhereB. now and thenC. from time to timeD. upward5. The best title for this passage is _____.A. Human SufferingB. I Found Joy and LoveC. Three Kinds of LifestylesD. What I Have Lived ForPassage 2Artificial light in winter means we no longer have to go to bed when it gets dark. We can also get up before it is light. This means we can have a summer sleep pattern all year round.Animals sleep more during winter than summer. Researchers in America wanted to find out whether humans might want to do the same on a winter day without artificial light. People observed in the research did sleep longer, usually up to 11 hours. However, winter sleep seems to be interrupted by periods of quiet ‘wakefulness’ like those experienced in meditation.These were found to be very restful. The study found that modern humans are not getting enough sleep.6. The topic of the passage is _____ .A. artificial lightB. natural lightC. human sleepD. animal sleepPassage 3Throughout the history of life, there have been many major upheavals in which whole groups of animals were replaced by others. Perhaps the most famous was the replacement of the dinosaurs by the mammals 65 million years ago. Another major change occurred 150 million years earlier, when the dinosaurs took over the position of dominance that had been held for80 million years by mammal-like reptiles.What triggered these great upheavals? Scientific thinking about the various factors that might have been responsible for such replacements has undergone some significant changes of its own. At times, for example, scientists have suggested thatmammals caused the extinction of the dinosaurs by eating their eggs or by competing for the same food resources. Now, however, most people are convinced that the mammals played only a minor role, if any, and that, instead, environmental change was primarily responsible. The mammals apparently sat around for 150 million years in the Mesozoic undergrowth until, with the extinction of the dinosaurs, they had their opportunity to radiate into the available niches.7. What is the main idea of the passage?A. Mammals caused the extinction of dinosaurs by eating their eggs.B. Some species of animals have been replaced by others due to radical environmentalchanges.C. Scientific theories about the reasons for the extinction of certain reptiles have changed overthe years.D. Mammals and dinosaurs competed for the same food source.Passage 4According to the World Bank the Kingdom of Bhutan is the second poorest country in the world(A), but there is no unemployment (B), no begging and almost no crime.Jigme Singye Wangchuck, the ‘Dragon King’, is the world’s youngest hereditary ruler, but he says that the country is more democratic than any other in the region. He travels round Bhutan, showing himself to the people and listening to their opinions. Although this is a very old country the monarchy is quite new; until this century it was theocracy run by Buddhistpriests. There is still a very strong religious feeling and there are 1,300 monasteries in a nation of only 1 million people.Bhutan allows only 2,000 tourists a year, but no multinational companies even though it is very short of capital(C). It takes no help from the USA or Russia. Students who go abroad to study must spend 6 months when they return in remote villages to ‘rediscover their roots’before going back into Bhutanese society.Although the people are poor they are content. The atmosphere is relaxed and traditional have hardly changed since the Middle Ages. Archery is t he country’s major sport and folk dances are the main forms of entertainment.8. Which of the following is untrue?A. Bhutan is one of the poorest countries in the world.B. There is no unemployment in Bhutan.C. Bhutan is short of financial aids.D. The people of Bhutan are not at all satisfied with their life.Passage 5In the Atlantic some 574 ships were sunk between 1939 and 1945.(A) High though this figure is, together with the complementary loss of over twenty thousand seamen, it must be seen in relation to the fact that merchant ships made seventy-five thousand crossings, sailing in two thousand two hundred convoys (D). Indeed, at peak periods on the Atlantic, there were no less than seven hundred ships at sea at the same time. To visualize such a heterogeneous fleet of steamships in transit at any given moment across the great ocean is a succinct way of appreciating how the picture had changed in the century since the Britannia thrashed her lonely course over three thousand empty miles. (B) Now on the great steamship lanes, no ship islikely to be alone for long. Radio and radar have both ‘shortened in’the world. The sense of wonder has, generally speaking, left the Atlantic and gone elsewhere perhaps into space.9. Which is not true according to the passage?A. About 100 ships were sunk each year in the Atlantic during the period from 1939 to 1945.B. When Britannia first sailed the Atlantic no other ship could be seen on the ocean.C. There were as many as 700 ships crossing the Atlantic at any time.D. A total of 2,200 ships sailed across the Atlantic during that period of time.。

以下是店铺为大家搜索整理的英语四级考试阅读练习题附答案，希望能给大家带来帮助!The motor vehicle has killed and disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood on the street flows essentially from uncivil behavior of drivers who refuse to respect the legal and moral rights of others. So the massacre on the road may be regarded as a social problem.In fact, the enemies of society on wheels are rather harmless people or ordinary people acting carelessly, you might say. But it is a principle both of law and common morality that carelessness is no excuse when one's actions could bring death or damage to others. A minority of the killers go even beyond carelessness to total negligence.Researchers have estimated that as many as 80 per cent of all automobile accidents can be attributed to the psychological condition of the driver. Emotional upsets can distort drivers' reactions, slow their judgment, and blind them to dangers that might otherwise be evident. The experts warn that it is vital for every driver to make a conscious effort to keep one's emotions under control.Yet the irresponsibility that accounts for much of the problem is not confined to drivers. Street walkers regularly violate traffic regulations; they are at fault in most vehicle walker accidents. And many cyclists even believe that they are not subject to the basic rules of the road.Significant legal advances have been made towards saferdriving in the past few years. Safety standards for vehicle have been raised both at the point of manufacture and through periodic road-worthiness inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate has decreased. But the accident experts still worry because there has been little or no improvement in the way drivers behave. The only real and lasting solution, say the experts, is to convince people that driving is a skilled task requiring constant care and concentration. Those who fail to do all these things pose a threat to those with whom they share the road.62. The word “massacre” in line 3 paragraph one means _____A) mass-killing.B) disaster.C) tragedy.D) accident.63. What is the author's main purpose in writing the passage?A) T o show that the motor vehicle is a very dangerous invention.B) To promote understanding between careless drivers and street walkers.C) To discuss traffic problems and propose possible solutions.D) To warn drivers of the importance of safe driving.64. According to the passage, traffic accidents may be regarded as a social problem because _____.A) autos have become most destructive to mankindB) people usually pay little attention to law and moralityC) civilization brings much harm to peopleD) the lack of virtue is becoming more severe65. Why does the author mention the psychologicalcondition of the driver in Paragraph Three?A) To give an example of the various reasons for road accidents.B) To show how important it is for drivers to be emotionally healthy.C) To show some of the inaccurate estimations by researchers.D) To illustrate the hidden tensions in the course of driving.66. Who are NOT mentioned as being responsible for the road accidents?A) Careless bicycle-riders.B) Mindless people walking in the street.C) Irresponsible drivers.D) Irresponsible manufactures of automobiles.答案解析:62-66：ACBBD【英语四级考试阅读练习题附答案】。

Duringtheir lifetime,it can be expected that of these 3000 about 23 will be murdered,30will die in traffic accidents, and nearly 750 will be killed by a smoking-relateddisease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,severalimportant issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist.

Some research has shown t hat perhaps eighty percent of all human illnessesare related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to causecertain different illnesses because of the food that is characteristic in thesecultures. That food is related to illness is nto a new discovery. In 1945, about35 years ago, government researchers realized that nitrates, commonly used topreserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all thetime to know which things on the packaging labels of processed food are helpful orharmful. The additives which we eat are not all so direct. Farmers often givepenicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not formedical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food andDrug Administration(FDA) has tried repeatedly to control these procedures, thepractices continue.is the best possible title of the passage?and Foodand Healthand Healthand Drugof the following statements is NOT ture?are always given to animals for medical reasonsof the additives in our food are added to the food itself and some are given tothe living animalshave known about the potential dangers of food additives for over thirty-five years. may cause forty percent of cancer in world.has science done something harmful to mankind?of science , diseases caused by polluted food haven been virtually eliminated.has caused a lack of information concerning the value of food.of the application of science,some potentially harmful substances have been added to food.scientists have preserved the color of meats,but not of vegetables.are nitrates used for?preserve flavor in packaged foods.preserve the color of meats.are the objects of research.cause the animals to become fatter.word 'carcinogenic' most nearly means '_____'.答案： cacbd大学英语四级阅读理解试题40 篇之六（含答案）As the pace of life continues to increase ,we are fast losing the art of relaxation.

But relaxation is essential for a healthy mind andbody.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of s tress is vitalto provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual.Somepeople are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusualdifficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the sameresponse.

A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher andarchitect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo SanFrancisco poet Steve Gakin, and a group that called itself the Hog Farm, lived inold school huses and traveled around the United States.

The first isthe sort of brain he is born with. Humanbrains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individualwill have a low order of intelligence unless he has opportunities to learn. So thesecond factor is what happens to the individual — the sort of environment in whichhe is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence ofwhich he is capable.The importance of environment in determining an individual's intellingence can bedemonstrated by the case history of the identical twins, Peter and Mark X. Beingidentical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they wereplaced in separate foster homes. Peter was reated by parents of low intelligencein an isolatedcommunity with poor educational was reared inthe home of well-to-do parents who had been to college.

But none of the other planets in our solar system are capable of supportinglife at present. One possible solution to the problem, however,has recently beensuggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost aslarge as earth itself. The difficult is that Venus is much hotter than the earthand there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similarto those on soon as this has been done, the algae will be placed in small Spaceship will then fly to Venus and fire the rockets into the atmosphere .In rockets.a fairlyshort time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but beforman can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain willeventually fall and in a few years something like earth will be reproduced on Venus. long run, the most insoluble problem caused by population growth on earth willprobably be the lack of ______.Sagan believes that Venus might be colonized from earth because _____might be possible to change its atmosphereatmosphere is the same as the earth'sis a good supply of water on Venusdays on Venus are long enoughVenus there is a lot of ________.dioxidemonoxideare plants that can____.in very hot temperaturesin very cold temperaturesoxygenof the above5.Man can land on Venus only when_______.algae have done their workatmosphere becomescooler oxygenrains there答案： cabdd大学英语四级阅读理解试题40 篇之十一（含答案）What is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologiststell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we growup----we are born with our you happen to love brown, you did so, as soon as youopened your eyes, or at least as soon as you could see clearly.Colours do influence our moods----there is no doubt about it .A yellow room makesmost people feel more cheerful and more relaxed than a dark green one; and a reddress brings warmth and cheer to the saddest winter day. On the other hand ,blackis depressing. A black bridge over the Thames River, near London, used to be thescene of more suicides than any other bridge in the area ----until it was repainter number of suicide attempts immediately fell sharply ;perhaps it would have falleneven more if the bridge had been done in pink or baby blue.Light and bright colours make people not only hppier but more active.

Things which were considered impolitemany years ago are now acceptable. Just a few years ago, it was considered impolite behaviour for a man to smoke on street. No man who thought of himself by smokingwhen a lady was in a room.Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't it matter? Should you use both hands whenyou are eating? Should leave one in your lap,or on the table?The Americans and the British not only speak the same language but also share a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a wonman or offer their seat to a woman , and so will most Americans. Promptness is important both in England and in America. That is , if a dinner invitation isfor 7 o'clock , the dinner guest either arrives close to that time or calls up toexplain his delay.The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable-----especially if they are your guests. Whenthe food was served , one of the guests strated to eat his peas with a knife . Theother guests were amused or shocked , but the host calmly picked up his knife andbegan eating in the same way. It would have been bad manners to make his guest feel foolish or uncomfortable.one has accepted a dinner invitation ,what should he do if he is tobe late for the dinner?should find an excuseshould adk for excuse.should say sorry。

In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood.Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily. Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools andmachines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.?1.
