英語六級閱讀備考練習題及答案 1
The life story of the human species goes back a million years, and there is no doubt that man came only recently to the western hemisphere. None of the thousands of sites of aboriginal habitation uncovered in North and South America has antiquity comparable to that of old World sites. Man‘s occupation of the New World may date several tens of thousands of years, but no one rationally argues that he has been here even 100,000 years. Speculation as to how man found his way to America was lively at the outset, and the proposed routes boxed the compass. With one or two notable exceptions, however, students of American anthropology soon settled for the plausible idea that the first immigrants came b way of a land bridge that had connected the northeast comer of Asia to the northwest corner of North America across the Bering Strait. Mariners were able to supply the reassuring information that the strait is not only narrow – it is 56 miles wide – but also shallow, a lowering of the sea level there by 100 feet or so would transform the strait into an isthmus (地峽). With little eels in the way of evidence to sustain the Bering Strait land bridge, anthropologists (人類學家) embraced the idea that man walked dryshod (不濕鞋的) from Asia to America. Toward the end of the last century, however, it became apparent that the Western Hemisphere was the New World not only for man but also for a host of animals and plants. Zoologists and botanists showed that numerous subjects of their respective kingdoms must have originated in Asia and spread to America. These findings were neither astonishing nor wholly unexpected. Such spread of populations is not to be envisioned as an exodus or mass migration, even in the case of animals. It is, rather, a spilling into new territory that accompanies increase in numbers, with movement in the direction of least population pressure and most favorable ecological conditions. But the immense traffic in plant and animal‘s forms placed a heavy burden on the Bering Strait land bridge as the anthropologists ahead envisioned it. Whereas purposeful men could make their way across a narrow bridge, the slow diffusion of plant and animals would require an avenue as a continent and available for ages at a stretch.
1.The movement of plants and animals form Asia to America indicates ______.
A.that they could not have traveled across the Bering Strait
B.that Asia and the Western hemisphere were connected by a large land mass
C.that the Bering Sea was an isthmus at one time
D.that migration was in the one direction only
2.The author is refuting the notion that _____.
A.life arose in America independently of life in Europe
B.the first settlers in America came during the sixteenth century
C.a large continent once existed which has disappeared
D.man was a host to animals and plants
3.By using the words ―boxed the compass ―(in Line 7) the author implies that _____.
A.the migration of mankind was from West to East
B.the migration of mankind was from East to West
C.mankind traveled in all directions
D.mankind walked from Asia to America
4.One reason for the migration not mentioned by the author is _____.
A.overcrowding B.favorable environmental conditions
C.famine D.the existence of a land bridge
5.We may assume that in the paragraph that follows this passage the author argues about______.
A.the contributions of anthropologist
B.the contributions of zoologists and botanists
C.the contributions made by the American Indians
D.the existence of a large land mass between Asia and North America
答案:BCCCD
英語六級閱讀備考練習題及答案 2
Plastic, it seems, is no longer fantastic. Even Hollywood, that factory of artifice (欺騙), is demanding areturn to reality when it comes to women’s bodies.
Disney Studios recent casting call for female extras for the fourth Pirates of the Caribbean film included a surprise announcement: "Must have real breasts. Do not submit if you have implants (移植物)." Surgically enhanced breasts might still be considered sexy or essential by airhead starlets and models. but the new buzzword(時髦語) in America is"authenticity". Thats why. for women in the public eye. having fake breasts is looking increasingly less like a career move and more like career suicide. Another indication thatfake breasts are going bust is the fact that television shows such as Extreme Makeover and The Swan (TV which promised to nip and tuck ordinary women into goddesses) have been cancelled. while statistics from theAmerican Society for Aesthetic Plastic Surgery show that the number of breast enlargements in America fellfrom 365,000 to 312,000 last year.
In many surveys. research has shown that the larger the breasts, the more stupid a woman is considered to be. Other women,meanwhile, consider women with large breasts as a threat-so having a surgical enhancement is a lose-lose situation. Chantelle Houghton (from Big Brother remember her?) almost immediately regrettedgelling implants to boost her chest and admits that they were "taking over her life". and she had io resort to physiotherapy to deal with the back pain they caused. Even Sharon Osbourne, voted the queen of nip and tuck(整容手術), said recently: "I wish Id never had my breasts done. Its like having a waterbed on your chest I hate them. I want to have the bags taken out-then Ill put them on eBay."
The more stories we hear like this the better. because then perhaps young women will realize that large breasts aren’t che assets they think they are-or Hollywood has made them out to be.
1. What is the new trend in Hollywood as to women’s bodies?
2. For mindless starlets and models. plastic breasts might be___________________.
3. That surgically enhanced breasts are not popular is manifested by the______________ of some TV shows.
4. According to many surveys. if a woman has large breasts. she will be regarded as_______________by otherwomen.
5. The author hopes that through some real stories, young women can be aware that large breasts____________________as they think.
答案:
1.[A return to reality.]
[定位]根據題干中的Hollywood和womens bodies查找到第1段第2句。
解析:本段第1句中的no longer道出整形潮流的改變。第2句指出,好萊塢對女性身材也要求回歸真實自然,題干中as towomens bodies對應原文中的when it comes to womens bodies,答案可在該句主句中找到。
2.[sexy or essential]
[定位]根據題干中的starlets and models查找到第2段第2句。
解析:題干中的mindless和plastic breasts分別為原文中airhead和surgically enhanced breasts的同義替換,所以原文中considered后的sexy or essential為本題答案。
3.[cancellation]
[定位]根據題干中的.TV shows查找到第2段第4句。
解析:根據空白處前后的冠詞和介詞,推斷這里需要填入一個名詞。該句提到,另一個隆胸潮流不再的跡象,就是有些節(jié)目被取消了(have been cancelled),因此需將cancelled轉化為其名詞形式cancellation。
4.[a threat]
[定位]根據題干中的surveys, large breasts以及other women查找到第3段第2句。
解析:題干將原文主動句改成了被動句,原文中的consider... as 對應題干中的regarded as,故原文中的as的賓語a threat就是答案。
5.[arent the assets]
[定位]根據題干中的young women,large breasts以及they think查找到第4段。
解析:原文最后一段說,這樣的真實故事聽得越多,也就越明白豐滿的胸部并不像想象中的那樣是一種優(yōu)勢,題干表達相同的意思,比較原文與題干,可知arent the assets為答案。
英語六級閱讀備考練習題及答案 3
Depending on which player you ask, the "Fevernova" ball that sports equipment maker Adidas says provides the ultimate soccer experience is Uncontrollable, too big or just simply "stupid". The ball also has its fans, like Englands David Beckham. but so far they seem to have been outnumbered by critics.
Adidas says the ball. splashed with gold coloring. is quite simply the best around-25 percent more accurate than the ball used at France 98 thanks to meticulous testing by scientists in Germany.
The tongue-twisting nature of its contents confirms that the World Cup ball has come a long way from the leather-and-laces variety that was common as recently as the 1960s.
The Fevernovas secret. Adidas says. is its radically improved Syntactic foam and unique knitted Raschel fabric.
Given that this is supposed to make the ball faster and provide the freekick specialists like Beckham withmore power, it may not be surprising that goalkeepers like Buffon are unhappy. Spain goalkeeper Pedro Contreras said the bail acts "strangely", while Danish keeper Thomas Sorensen admitted gloomily that it would probably result in more spectacular goals. "As a goalkeeper, you have to live with the fact that the makers create balls for the benefit of strikers." he said before leaving Copenhagen for South Korea.
But outfield players have also weighed in with criticism, many saying the ball is too light and therefore hard to control. "It’s big and its too light," Japans Jiji news agency quoted Brazilian forward Edilsonas saying earlier this month. while striker Rivaldo said it soared too far when kicked.
Journalists at the main press centre in Yokohama have been given the chance to try out the Fevernova from the penalty spot, with the aim of hitting special targets in the goal. So far. few have been able to scoremore than five out of ten, although this may have little to do with the quality of the ball.
Putz. admits that the ball is on the light side of FIFAs 420 to 445 gram weight requirement. but says it is no bigger than previous balls.
The controversy over the ball also has an off-pitch dimension. Industry insiders say it may be no coincidence that players from Brazil. sponsored by Adidas rival Nike, have been among the balls most vociferous critics.
The same might go for the praise dished out for the ball by Beckham. one of the main players used to promote Adidas equipment.
1. How does Adidas describe the "Fevernova”ba11?
A) The experience provided by the ball is the best so far.
B) The ball is almost impossible to control because of its large size.
C) The ball has gone through a long way of development.
D) The experience provided by the ball is most welcome by strikers.
2. What does the author think about the Syntactic foam and unique Raschel fabric chat are used to make theball?
A) The materials have long been used in history.
B) The materials do not sound Familiar.
C) The materials are new and advanced.
D) The materials improve che precision of the ball.
3. The goalkeepers tend to admit reluctantly that_____________.
A) the ball is too strange to control
B) the ball is so light that it goes too fast
C) the ball may make the game more thrilling
D) the ball may help to enhance the strikers skills
4. Which of the following js true according to Putz?
A) The ball is lighter than but of the same size as the previous ones.
B) The ball should have been heavier to meet the required weight.
C) The ball should have been bigger than the previous ones.
D) The ball is light but still meets the weight requirement.
5. According to industry insiders. Beckhams comment on the ball_____________.
A) is justified in his daily training
B) is out of commercial purpose
C) goes as radical as the Brazilian players
D) is similar to that by the Brazilian players
答案:
1.阿迪達斯如何形容“飛火流星”球?
A) 這個球所帶來的體驗是迄今為止最好的。
B) 這個球基本上不可能控制,因為體積太大了。
C) 這個球已經經過了很長時間的開發(fā)。
D) 這個球所帶來的體驗最為前鋒所歡迎。
[A]首段首句中的ultimate experience表明Adidas公司認為“飛火流星”是至今最完美的足球,因此選項A為本題答案。
2. 作者怎么看用來制造這個球的復合泡沫塑料以及獨特的拉歇爾經編針織物?
A) 在歷史上這種材料已經使用了很長時間。
B) 這種材料聽上去很陌生。
C) 這種材料是新型的先進的.。
D) 這種材料提高了球的精準度。
[B]第3段開頭的tongue-twisting表明人們對于制作“飛火流星”的材料及其功能都并不熟悉,因此選項B為本題答案。第3段表明“飛火流星”的材料經過很長時間才研制出來,并非長久以來一直在使用,由此可見。選項A不正確;第4段是Adidas公司的看法,并非作者的看法,因此選項C不符合題意;根據第2段可判斷選項D也是Adidas公司的看法。而并非作者的看法。
3.守門員會不情愿地承認,______________。
A) 這個球很奇怪,很難控制 B)這個球很輕,速度太快
C) 這個球會讓整場比賽更加精彩 D)這個球可以提高前鋒的技藝
[C]本題題干中的reluctantly是關鍵詞,指出本題要求查找的是“飛火流星”具有的優(yōu)點,而這個優(yōu)點是守門員們不想面對或承認的。選項C與第5段第2句中的gloomily that it would probably result in more spectacular goals 內容相近,符合題意.為本題答案。
4.根據Putz所說,下列哪一種說法是正確的?
A) 相比以前同樣大小的球,這種球更加輕。
B) 這種球本應該更重一些,才能達到要求的重量。
C) 這種球本應該比以往的球更大一些。
D) 這種球很輕,但是仍能達到要求的重量。
[D]本題要求正確理解第8段中的on the light side of FIFAs 420 to 445 gram weight requirement,該句應理解為“飛火流星”重量偏輕,但仍屬于要求范圍內,選項D是正確的理解,為本題答案。
5. 根據業(yè)內人士所稱,貝克漢姆對這種球的評價_________________.
A) 是根據他平時的訓練所作出的
B)是出于商業(yè)目的的考慮
C) 跟巴西球員的評價一樣激烈
D) 與巴西球員的評價類似
[B]概括最后兩段可以得知,業(yè)內人士認為對“飛火流星”的批評和稱贊都與贊助公司有關,也就是說,這些評價都出于商業(yè)目的,由此可推斷選項B為本題答案。選項A中的training在原文根本沒有提及;末段開頭的The same might go 表明的是Beckham和巴西球員對“飛火流星”做出的評價源于相似的目的,而非表明他們的評價內容相似,程度相同,因此選項C和D都不正確。
英語六級閱讀備考練習題及答案 4
An industrial society, especially one as centralized and concentrated as that of Britain, is heavily dependant on certain essential services: for instance, electricity supply, water, rail and road transport, the harbors. The area of dependency has widened to include removing rubbish, hospital and ambulance services, and, as the economy develops, central computer and information services as well. If any of these services ceases to operate, the whole economic system is in danger.
It is this interdependency of the economic system that makes the power of trade unions such an important issue. Single trade unions have the ability to cut off many economic blood supplies. This can happen more easily in Britain than in some other countries, in part because the labor force is highly organized. About 55 per cent of British workers belong to unions, compared to under a quarter in the United States. For historical reasons, Britains unions have tended to develop along trade and occupational lines, rather than on an industry-by-industry basis, which makes wage policy, democracy in industry and the improvement of procedures for fixing wage levels difficult to achieve.
There are considerable strains and tensions in the trade union movement, some of them arising from their outdated and inefficient structure. Some unions have lost many members because of industrial changes. Others are involved in arguments about who should represent workers in new trades. Unions for skilled trades are separate from general unions, which means that different levels of wages for certain jobs are often a source of bad feeling between unions. In traditional trades which are being pushed out of existence by advancing technologies, unions can fight for their members disappearing jobs to the point where the jobs of other unions members are threatened or destroyed. The printing of newspapers both in the United States and in Britain has frequently been halted by the efforts of printers to hold on to their traditional highly-paid jobs.
21. Why is the question of trade union power important in Britain?
A. The economy is very much interdependent.
B. Unions have been established a long time.
C. There are more unions in Britain than elsewhere.
D. There are many essential services.
22. Because of their out-of-date organization some unions find it difficult to______.
A. change as industries change B. get new members to join them
C. learn new technologies D. bargain for high enough wages
23. Disagreements arise between unions because some of them
A. try to win over members of other unions
B. ignore agreements
C. protect their own members at the expense of others
D. take over other unions jobs
24. It is difficult to improve the procedures for fixing wage levels because______.
A. some industries have no unions
B. unions are not organized according to industries
C. only 55 per cent of workers belong to unions
D. some unions are too powerful
25. Which of the following is NOT TRUE?
A. There are strains and tensions in the trade union movement.
B. Some unions have lost many members.
C. Some unions exist in the outdated structure.
D. A higher percentage of American workers belong to unions than that of British workers.
21. A 22. A 23. C 24. B 25. D

The History of Chinese Americans
Chinese have been in the United States for almost two hundred years. In fact. the Chinese had business relations with Hawaii prior to relations with the mainland when Hawaii was not yet part of the United States.But United States investments controlled the capital of Hawaii at that time. In 1788,a ship sailed from Guangzhou to Hawaii. Most of the crewmen were Chinese. They were considered the pioneers of Hawaii. The Immigration Commission reported that the first Chinese arrived in the United States in 1820. eight in 1830 andseven hundred and eighty in 1850. The Chinese population gradually increased and reached 64,199 in 1870.
For many years it was common in the United States to associate Chinese Americans with restaurants and laundries. People did not realize that the Chinese had been driven into these occupations by the prejudice anddiscrimination that faced them in this country.
The First Chinese to reach the mainland United States came during the California Gold Rush of 1849. Like most of the other people there, they had come to search for gold. In that largely unoccupied land,the men staked a claim for themselves by placing markers in the ground. However. either because the Chinese were sodifferent from the others or because they worked so patiently that they sometimes succeeded in turning a seemingly worthless mining claim into a profitable one, they became che scapegoats of their envious competitors. They were harassed in many ways. Often they were prevented from working their claims; some localities even passed regulations forbidding them to own claims. The Chinese therefore started to seek out other ways of earning a living. Some of them began to do che laundry for the white miners; others set up small restaurants. (There were almost no women in California in those days,and the Chinese filled a real need by doing this“womans work”.) Some went to work as farmhands or as fishermen.
In the early 1860s many more Chincse arrived in California.This time the men were imported as work crews to construct the first transcontinental railroad.They were sorely needed because the work was so strenuousand dangerous, and it was carried on in such a remote part of the country that the railroad company could not find other laborers for the job. As in the case of their predecessors,these Chinese were almost all males; and like them, too, they encountered a great deal of prejudice. The hostility grew especially strong afrer the railroad project was complete, and the imported laborers returned to California-thousands of them, all out of work. Because there were so many more of them this time,these Chinese drew even more attention than the earlier group did. They were so very different in every respect: in their physical appearance,including a long“pigtail”at the back of their otherwise shaved heads; in the strange, non-Western clothes they wore; in their speech (few had learned English since they planned to go back to China); and in their religion. They were contemptuously called “heathen Chinese” because there were many sacred images in their houses of worship.
When times were hard. they were blamed for working for lower wages and taking jobs away from white men. who were in many cases recent immigrants themselves. Anti-Chinese riots broke out in several cities. culminating in arson and bloodshed. Chinese were barred from using the courts and also from becoming American citizens. Californians began to demand that no more Chinese be permitted to enter their state. Finally. in 1882. they persuaded Congress to pass the Chinese Exclusion Act, which stopped the immigration of Chinese laborers. Many Chinese rerurned to their homeland, and their numbers declined sharply in the early part of this century. However. during the World War II,when China was an ally of the United States. the Exclusion laws were ended; a small number of Chinese were allowed to immigrate each year, and Chinese could become American citizens. In 1965, in a general revision of our immigration laws,may more Chinese were permitted to settle here,as discrimination against Asian immigration was abolished.
From the start,the Chinese had lived apart in their own separate neighborhoods, which came to be known as “Chinatowns”. In each of them the residents organized an unofficial government to make rules for the community and to settle disputes. Unable to find jobs on the outside, many went into business for themselves-primarily to serve their own neighborhood. As for laundries and restaurants. some of them soon spread to other parts of the city,since such services continued to be in demand among non-Chinese, too. To this day. certain Chinatowns. especially those of San Francisco and New York. are busy. thriving communities, which have become great attractions for tourists and for those who enjoy Chinese food.
Most of todays Chincse Americans are the descendants of some of the early miners and railroad workers. Those immigrants had come from the vicinity of Canton in Southeast China. where they had been uneducated farm laborers.The same kind of young men,from the same area and from similar humble origins,migrated to Hawaii in those days. There they fared far better, mainly because they did not encounter hostility. Some married native Hawaiians, and other brought their wives and children over. They were not restricted to Chinatownand many of them soon became successful merchants and active participants in general community affairs.
Chinese Americans retain many aspects of their ancient culture. even after having lived here for several generations. For Example, their family ties continue to be remarkably scrong (encompassing grandparents. uncles, aunts, cousins. and others). Members of the family lend each other moral support and also practical help when necessary. From a very young age children are imbued with the old values and attitudes. including respect for their elders and a feeling of responsibility to the family. This helps co explain why there is so little juvenile delinquency (少年犯罪 ) among them.
The high regard for education which is deeply imbedded in Chinese culture.and the willingness to work veryhard to gain advancement, are other noteworthy characteristics of theirs. This explains why so many descendants of uneducated laborers have succeeded in becoming doctors. lawyers, and other professionals.(Many ofthe most outstanding Chinese American scholars,scientists, and artists are more recent arrivals, who come from Chinas former upper class and who represent its high cultural traditions.)
Chinese Americans make up only a tiny fraction of our population; there are fewer than half a miilion, living chiefly in California. New York. and Hawaii. As American attitudes toward minorities and toward ethnicdifferences have changed in recent years, the long-reviled Chinese have gained wide acceptance. Today, they are generally admired for their many remarkable characteristics, and are often held up as an example worth following. And their numerous contributions to their adopted land are much appreciated.

2.[C][定位]根據題干中的California Gold Rush,restaurant和laundry定位到第3段倒數(shù)第2、3句。
解析:原文該句中的this“womans work”指的就是前一句提到的laundry和restaurant的工作,可見本題應選C。
3.[B][定位]根據題干中的In the early 1860s定位到第4段開頭兩句。
解析:原文該段第2句中的work crews to construct the first transcontinental railroad表明那時候華人到美國是為了修建鐵路,可見本題應選B。
4.[D][定位]根據題干中的Few和learned English定位到第4段倒數(shù)第2句。
解析:原文該句中括號里的內容明確表明很少華人學習英語的原因是他們都計劃要回中國,也就是他們沒想過要長久留在美國,因此本題應選D。
5.[C][定位]根據題干中的The Chinese Exclusion Act定位到第5段倒數(shù)第2句。
解析:原文該句中的during the World War II... the Exclusion laws were ended明確表明本題應選C。干擾項D中的1965在原文該段末句提及,但與Chinese Exclusion Act無關,故不能選。

The food irradiation process is a simple one. The new U.S. plant, Vindicator of Florida Incorporated in Mulberry, Fla., uses a material called cobalt 60 to irradiate food. Cobalt 60 is radioactive isotope (form) of the metallic element cobalt. Cobalt 60, which gives off radiation in the form of gamma rays, is also used for radiation therapy for cancer patients and for sterilizing hospital equipment. The radioactive isotope is created by bombarding cobalt with subatomic particles in a nuclear reactor. However, irradiation plants do not themselves contain nuclear reactors.
In the irradiation plant, food is exposed to thin rods of cobalt 60. The rods give off gamma rays, which disrupt chemical processes in contaminating organisms. The disruption breaks down the cell walls of organisms or destroys their genetic material. The dose, set by the U.S. Food and Drug Administration (FDA), is enough to kill organisms on food, but not enough to produce significant changes in the food itself.
Although irradiation slightly decreases the nutritive value of foods, the loss is less than that produced by some other methods of food preservation. Canning, for example, results in a much greater loss of nutrients.
Those who object to irradiation say that the process may create substances not found in nonirradiated food. Since the 1960’s researchers have studied irradiated food at microscopic levels to try to find such substances, called unique radiolytic products. After reviewing these studies, the FDA determined that compounds formed during irradiation are similar to substance found in nonirradiated foods and are not dangerous to consume.
Destruction of microorganisms that cause illness is an important goal of irradiation. About 250 million cases of food poisoning or 1 per person—occur every year in the U.S., according to FDA estimates. Food poisoning can cause vomiting, diarrhea, fever, headache—and, occasionally, death.
Because of the apparent safety of food irradiation, and the problems presented by contaminated food, scientific groups—including the American Medical Association, the World Health Organization, and the United Nations food and Agriculture Association—have voiced nearly universal support for the process. Worldwide, 38 nations have approved irradiation for 355 products.
Like microwave ovens, food irradiation has aroused apprehension and misunderstanding. Yet it has been scrutinized more thoroughly than other methods of food treatment that we have come to regard as safe, and it appears to be a method whose time has come.
1.Cobalt 60, besides irradiating food, is also employed to ___.
A.detect metallic flaws
B.run a nuclear reactor
C.cure cancer patients
D.strengthen concrete walls
2.Gamma rays used to irradiate food ___.
A.are generally not strong enough to destroy contaminating organisms
B.do not bring about significant changes in the food itself
C.may destroy some of the nutrients in the food
D.should be submitted to FDA for approval
3.Irradiated food ___.
A.certainly loses its nutritive value
B.maintains its nutritive value no different from the nonirradiated
C.keeps its nutritive value better than canned food
D.is recommended as the best of all preserved foods
4.With cases of food poisoning increasing, ___.
A.food irradiation should be carried out with care
B.it is more urgent to irradiate foods
C.medical researches into treatment of the diseased should be strengthened
D.Americans are beginning to accept food irradiation
5.The passage may be taken from ___.
A.a news report
B.a textbook of food processing
C.a book of popular science
D.a manual of food irradiation
答案:CBCCD

In the last two hundred years there have been great changes in the method of production of goods. This is now also true of the building industry; for mechanization has been introduced. System building can save both time and money. The principle of system building is that the building is made from a set of standard units. These are either made at the building-site or at a factory. Some designers, in fact, are standardizing the dimensions of rooms. They are made in multiples of a single fixed length, usually ten centimeters. This is called a modular (標準件的) system, and it means that manufactures can produce standardized fittings at a lower cost. The most important fact about system building is its speed. A ten-storey flat, for example, can be completed in four months.
There are several new methods of system building. One is the panel method. In this case, the construction company sometimes erects a factory on the site. The walls and floors of the building, called panels, are cast in a horizontal or vertical position. Conduits for electrical wires and sleeves for pipes are cast in the panels when they are being made. The moulds for making these castings are situated all around the building.
After the concrete panels are cast, they are allowed to set and harden for a week. Next they are lifted by a tower crane on to any section of the building. There the panels are cemented together at their joints and the floor covering is laid.
After the panels have been cemented together, the crane lifts a case into the area. It contains all the fittings to be installed, such as wash-basins, radiators and pipes. Finishing tradesmen, such as plumbers, plasterers, painters and electricians, follow behind to complete the work.
In some building developments, in some countries, whole flats with internal features like their bathrooms, bedrooms and connecting stairs, and weighing as much as twenty tons, are carried to the building-site ready-made. A giant overhead crane is used to lift them into position. In the future, this method may become more widespread.
1. The main difference between panel method and the method discussed in the last paragraph is_______.
A. the latter uses ready-made internal features
B. panels are cast in a level position
C. the former is used to build walls and floors while the latter to construct bathrooms or bedrooms
D. the former is more expensive than the latter
2. Which of these statements is TRUE of system building?
A. It employs more men. B. It is difficult and dangerous.
C. It can save both time and money. D. It means less mechanization.
3. According to the passage, the principle of system building is that_______.
A. construction methods are safer
B. buildings are made from a set of standardized units
C. similar buildings can be produced
D. all units are produced on the site
4. The usual fixed length in the modular system is_______.
A. twenty centimeters B. ten millimeters
C. fifty centimeters D. ten centimeters
5. What lifts the concrete panels onto the building?
A. Cranes. B. Man-power.
C. Pulleys. D. Hydraulic jacks.

It is a curious paradox that we think of the physical sciences as “hard”, the social sciences as “soft,” and the biological sciences as somewhere in between. This is interpreted to mean that our knowledge of physical system is more certain than our knowledge of biological systems, and these in turn are more certain than our knowledge of social systems. In terms of our capacity of sample the relevant universes, however, and the probability that our images of these universes are at least approximately correct, one suspects that a reverse order is more reasonable. We are able to sample earth’s social systems with some degree of confidence that we have a reasonable sample of the total universe being investigated. Our knowledge of social systems, therefore, while it is in many ways extremely inaccurate, is not likely to be seriously overturned by new discoveries. Even the folk knowledge in social systems on which ordinary life is based in earning, spending, organizing, marrying, taking part in political activities, fighting and so on, is not very dissimilar from the more sophisticated images of the social system derived form the social sciences, even though it is built upon the very imperfect samples of personal experience.
In contrast, our image of the astronomical universe, or even if earth’s geological history, ca easily be subject to revolutionary changes as new data come in and new theories are worked out. If we define the “security” of our image of various parts of the total system as the probability of their suffering significant changes, then we would reverse the order for hardness and as the most secure, the physical sciences as the least secure, and again the biological sciences as somewhere in between. Our image of the astronomical universe is the least secure of all simply because we observe such a fantastically small sample of it and its record-keeping is trivial records of biological systems. Records of the astronomical universe, despite the fact that we learnt things as they were long age, are limited in the extreme.
Even in regard to such a close neighbor as the moon, which we have actually visited, theories about its origin and history are extremely different, contradictory, and hard to choose among. Our knowledge of physical evolution is incomplete and insecure.
1.The word “paradox” (Line 1, Para. 1) means “_____”.
A.implication B.contradiction
C.interpretation D.confusion
2.Accroding to the author, we should reverse our classification of the physical sciences as “hard” and the social sciences as “soft” because _______.
A.a reverse ordering will help promote the development of the physical sciences
B.our knowledge of physical systems is more reliable than that of social systems
C.our understanding of the social systems is approximately correct
D.we are better able to investigate social phenomena than physical phenomena
3.The author believes that our knowledge of social systems is more secure than that of physical systems because______.
A.it is not based on personal experience
B.new discoveries are less likely to occur in social sciences
C.it is based on a fairly representative quantity of data
D.the records of social systems are more reliable
4.The chances of the physical sciences being subject to great changes are the biggest because _____.
A.contradictory theories keep emerging all the time
B.new information is constantly coming in
C.the direction of their development is difficult to predict
D.our knowledge of the physical world is inaccurate
5.We know less about the astronomical universe than we don about any social system because ______.
A.theories of its origin and history are varied
B.our knowledge of it is highly insecure
C.only a very small sample of it has been observed
D.few scientists are involved in the study of astronomy

The difference between a liquid and a gas is obvious under the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and fill it to the level of a free surface. A gas forms no free surface but tends to diffuse throughout the 11 available; it must therefore be kept in a closed container or held by a gravitational field, as in the 12 of a planets atmosphere. The distinction was a 13 feature of early theories describing the phases of matter. In the nineteenth century, for example, one theory maintained that a liquid could be "dissolved" in a vapor without losing its identity, and another theory 14 that the two phases are made up of different kinds of molecules. The theories now prevailing take a quite different approach by emphasizing what liquids and gases have in 15 They are both forms of matter that have no 16 structure, and they both flow readily.
The fundamental similarity of liquids and gases becomes clearly apparent when the temperature and pressure are 17 somewhat. Suppose a closed container 18 filled with a liquid is heated. The liquid expands, or in other words becomes less dense; some of it evaporates. In contrast, the vapor above the liquid surface becomes denser as the evaporated molecules are 19 to it. The combination of temperature and pressure at which the densities become 20 is called the critical point.
A. added
B. case

Federal Reserve System, central banking system of the United States, popularly called the Fed. A central bank serves as the banker to both the banking community and the government; it also issues the national currency, conducts monetary policy, and plays a major role in the supervision and regulation of banks and bank holding companies. In the U.S. these function are the responsibilities of key officials of the Federal Reserve System: the Board of Governors, located in Washington, D.C., and the top officers of 12 district Federal Reserve banks, located throughout the nation. The Fed’s actions, described below, generally have a significant effect on U.S. interest rates and, subsequently, on stock, bond, and other financial markets.
The Federal Reserve’s basic powers are concentrated in the Board of Governors, which is paramount in all policy issues concerning bank regulation and supervision and in most aspects of monetary control. The board enunciates the Fed’s policies on both monetary and banking matter. Because the board is not an operating agency, most of the day-to day implementation of policy decisions is left to the district Federal Reserve banks, stock in which is owned by the commercial banks that are members of the Federal Reserve System. Ownership in this instance, however, does not imply control; the Board of Governors and the heads of the Reserve banks orient their policies to the public interest rather than to the benefit of the private banking system.
The U.S. banking system’s regulatory apparatus is complex; the authority of the Federal Reserve is shared in some instances for example, in mergers or the examination of banks with other Federal Deposit Insurance Corporation (FDIC). In the critical area of regulating the nation’s money supply in accordance with national economic goals, however, the Federal Reserve is independent within the government, Income and expenditures of the Federal Reserve banks and of the board of governors are not subject to the congressional appropriation process; the Federal Reserve is self-financing. Its income ($20.2 billion in 1992) comes mainly from Reserve bank holdings of income-earning securities, primarily those of the U.S. government. Outlays ($1.5 billion in 1992) are mostly for operational expenses in providing services to the government and for expenditures connected with regulation and monetary policy. In 1992 the Federal Reserve returned 416.8 billion in earnings to the U.S. treasury.
1.The Fed of the United States ___.
A.function as China Bank
B.is the counterpart of People’s Bank of China
C.is subjected to the banking community and government
D.has 13 top officers who can influence the American financial market
2.The fact that stock in the Fed belongs to commercial banks ___.
A.doesn’t mean the latter is in control
B.means the latter is in control
C.means the latter is subjected to the Reserve banks
D.means the Reserve banks orient the latter’s policies
3.Which of the following statements is not true according to the passage?
A.The fed is a very big, complex and significant system which comprises many local banks.
B.All the commercial banks are not the components of Federal Reserve System.
C.Board of governors is the supreme policy-makers of America.
D.District Reserve banks rather than Board of governors perform the day-to-day policies.
4.The authority of the federal Reserve ___.
A.has to be shared with other establishments.
B.is exclusive at other times
C.isn’t limited by comptroller of the Currency and FDIC
D.is limited by Board of governors
5.Income of the Board of governors ___.
A.is borrowed from the U.S. treasury
B.is used by the government to make various policies
C.comes from the U.S. Treasury
D.is not granted by the government

The Amer ican Character
What do Americans believe in2? What is theAmerican character? These questions are hard toanswer, because there are so many Americans andthey believe in so many different things. However,the history of the United States does provide someunderstanding of certain basic characteristics thatmany Americans share .
One of the main reasons why the early settlers came to America was to escape the controlsthey had experienced in Europe. There , small groups of wealthy people prevented themfrom moving into a higher social position or becoming wealthy, and governmentsupportedchurches controlled their religious practices and beliefs. Because these early settlers wanted tobe free from such controls, they brought to America the view that the individual was supremelyimportant. The settlers were against the efforts of the church, the society, and particularly thegovernment, to control their actions. These controls came to be viewed as "un-American" .
This strong American belief in individualism has both positive and negative sides5 . On thepositive side, it has strengthened Americans’inventiveness and their belief in hard work. Onthe negative side, the belief in individualism has sometimes prevented Americans from usingtheir government to solve their common problems. Americans prefer not to have governmentsolutions to social problems.
The belief in individualism is a basic part of the American character. This belief has at least twoseparate parts — idealism and materialism6. Although these two beliefs are quite different,most Americans try to live with them both at the same time, and idealism and materialism areboth very much a part of the American character.
American idealism comes largely from the nation’s Protestant7 religious heritage . EarlyAmericans did not have to belong to any particular church to have this belief. It influenced allAmericans so strongly that idealism came to mean that each individual should possess a highmoral character, and should live by his or her own beliefs. This is what American idealismmeans today.
Americans also have a strong belief in materialism, that is, that each individual should gain asmuch wealth as possible. The American belief in materialism is partly a result of the nation’sgreat material abundance. The early settlers found a continent with great forests, rivers, andfertile farmland in abundance. It is not surprising that many viewed America as the land ofopportunity. 8
As the United States grew and developed, the supply of natural resources seemed endless,and so did the opportunities for personal economic advancement. Each generation had a chanceto become wealthier than their parents had been. Generation after generation of newimmigrants had the same opportunity. Americans eventually developed the belief that it wasalmost a duty to get rich.
