READING COMPREHENSION

Questions 71 to 75 are based on the following passage:

The failed Skylab will come screaming home to earth in disappointmentsometime next month, but it will fall we know not where.

That precise information is beyond even the calculations of scientistsand their computers.

The best they can tell us is that the space station, weighing 77 tons andas high as a 12-story building,

will break into hundreds of pieces that willbe scattered across a track 100 miles wide and 4,000 miles long.

We are again exposed to one of those unexpected adventures, or misadven-tures, of science that attracts our attention from the boring routines ofdaily existence and encourages us to think a lot about man's future.

What worries Richard Smith, the Skylab's director, is the'big pieces'that will come through the atmosphere. Two lumps, weighing 2 tons each, andten, weighing at least 1,000 pounds each, will come in at speeds of hundredsof miles an hour, and if they crash on land they will dig holes up to 100feet deep.

What worries us, with our lack of scientific knowledge and our quickimagination, is both the big and little pieces, although project officialssay there is a very small chance that anyone will be injured by them.

That's good to know , but it doesn't remove the doubts of the millionswho still remember the nuclear accident at Three Mile Island. That accidenttook place in 1979 in spite of what scientists had assured us as to thesafety of the nuclear reactor.

71. Where the Skylab will fall _______.

A) is kept secret

B) will be announced soon

C) is predicted by scientists

D) can't be predicted

72. The broken Skylab will be _______.

A) in two lumps--one weighing 2 tons and the other weighing 10 tons

B) falling with the force of a 12-story building

C) composed of 12 big pieces and hundreds of smaller pieces

D) an attractive scene to millions of people

73. The author suggests that _______.

A) the danger of the Skylab's fall has been overestimated

B) it's useless to worry over things you can't do anything about

C) computers can solve the problem caused by the broken Skylab

D) the danger of the Skylab's fall has been underestimated

74. The author refers to Three Mile Island _______.

A) because he fears that a piece of the Skylab may strike a nuclear power

plant

B) as a doubtful comment on the officials' words

C) because he is afraid of nuclear power

D) because the nuclear reactor there and the Skylab were built by the same

company

75. The author expresses his _______.

A) interest in the failure of the Skylab

B) willingness to give his advice

C) doubtful attitude toward scientists

D) eagerness to see more new scientific discoveries

Questions 76 to 80 are based on the following passage:

Any talk of the energy needs of the United States should include adiscussion of the Tennessee Valley Authority, a successful but sometimesquiet federal agency. The Tennessee valley Authority began life in 1933 asone of the public works agencies designed to help fight the Great Depression.The TVA was first meant to employ thousands of men to build a chain of damsdown the Tennessee River. These dams were to include electric plants forgenerating electricity to provide cheap power for the rural land in thevalley area.

Within ten years, most of the homes in the TVA area had electricity. Intwenty years, there were four times as many homes in the area with power.At first , TVA electrcity cost a penny per kilowatt. Many homes in the arearelied on electricity for heating. This results in criticism now that elec-tricity is more than three pennies per kilowatt. Other criticism has beenaimed at the TVA's other methods of generating power in 1975. The Authoritywas sued(?e??) for polluting the air with its

coal-generating plants. Anti-nuclear groups point out that the TVA would soon have a total of seventeenatomic reactor plants supplying power for its service area. But the TennesseeValley Authority has adjusted to the new times. It quickly became a modelfor pollution control at its coal plants. Just as quickly the TVA founditself an energy conserver as well as a producer. The TVA conducts freehome energy consultations and offers cheap loans to consumers who want toinstall insulation storm windows, solar energy equipment or woodburningstoves. The resulting decrease in demand has allowed the TVA to postponeor delay construction of two nuclear reactors. Instead, the Authority isbuilding a plant to extract coal gas from low-grade coal. Their first stepwill be to use the coal gas to make an ammonia(???à) fertilizer for farmersin the TVA service area. Their ultimate goal is to produce a syntheticfuel from the coal gas. The TVA will then be once again producing a cheapersource of energy and helping solve the nation's problems, several at atime.

76. The main idea of this passage is that ____________.

A) electricity purchased by TVA's customers has tripled in price.

B) the TVA has not served its function well.

C) the TVA is dangerous to the environment.

D) the TVA has always been a pioneer in the energy field.

77. According to the passage, which of the following statements is NOT true?

A) The Tennessee Valley Authority was created in 1933.

B) The TVA's initial function was to provide work for the unemployed.

C) The TVA has been making an effort in decreasing the number of nuclear reactor plants it depends on.

D) The TVA is interested in producing coal gas from low-grade coal.

78. We can conclude from the passage that ____________.

A) the TVA no longer supplies electricity for heating

B) before the time of the TVA, few homes in the Tennessee valley had electricity

C) the TVA has not had to rely on atomic reactor for its power

D) coal gas is expensive to produce

79. The passage suggests that ____________.

A) the TVA is now privately owned

B) the TVA is more interested in what is good for the nation than in making money

C) synthetic fule is cheaper to produce than electricity

D) ammonia fertilizers are nonpolluting

80. As used in this passage, the word "extract" means ____________.

A) burn B) reshape

C) defy D) remove from

Questions 81 to 85 are based on the following passage:

In the English educational system, students take three very importantexaminations. The first is the eleven-plus, which is taken at the age ofeleven or a little past. At one time the ability or aptitude shown on theeleven-plus would have determined if a child stayed in school. Now, however,all children continue in"comprehensive"schools, and the eleven-plus determines which courses of study the child will follow. At the age offifteen or sixteen, the students are tested for the Ordinary Level ofthe General Certificate of Education. This examination covers a widerange of subjects; once students have passed this exam, they are allowedto specialize, so that two-thirds or more of their courses will be inphysics, chemistry, classical languages, or whatever they wish to studyat greater length. The final examination, at eighteen, covers only thecontent of the special subjects. Even at the universities, students studyonly in their concentrated area, and very few students ever venture

out-side that subject again; in a real sense, the English boy or girl is aspecialist from the age of fifteen.

81. The purpose of this passage is to ______.

A) show why most English students are"specialists"

B) show the superiority of the English educational system

C) describe the three tests that the English educational system is basedon

D) discuss the inequalities of the English educational system

82. The exam for the Ordinary Level of the General Certificate of Education

is administrated at the age of ______.

A) fifteen B) eighteen

C) eleven D) thirteen

83. We may conclude from the passage that______.

A) the exam that is taken at age eighteen is easier than the other two exams

B) failure on the eleven-plus exam excludes a student from further

schooling

C) higher education is much narrower in scope in England than in

American

D) physics and chemistry are the two most popular courses of study

84. The passage suggests that ______.

A) most people in England are college educated

B) schooling is very closely controlled in England

C) the failure rate on eleven-plus exam is quite high

D) England's structured educational system has reduced the illiteracy

rate in that country dramatically

85. As used in the passage, the word "content" (in Line 12) means______.

A) difficulties B) framework

C) material D) pleasure

Questions 86 to 90 are based on the following passage:

What makes it rain? Rain falls from clouds for the same reason any-thing falls to Earth. The Earth's gravity pulls it. But every cloud ismade of water droplets or ice crystals. Why doesn't rain or snow fallconstantly from all clouds? The droplets or ice crystals in clouds areexceedingly small. The effect of gravity on them is minute. Air currentsmove and lift droplets so that the net downward displacement (¨°???¥) iszero, even though the droplets are in constant motion.

Droplets and ice crystals behave somewhat like dust in the air madevisible in a shaft of sunlight. To the casual observer, dust seems to actin a totally random fashion, moving about chaotically without fixed direc-tion. But in fact dust particles are much larger than water droplets andthey finally fall. The cloud droplet of average size is only 1/2500 inchin diameter. It is so small that it would take sixteen hours to fall halfa mile in perfectly still air, and it does not fall out of moving air atall. Only when the droplet grows to a diameter of 1/125 inch or largercan it fall from the cloud. The average raindrop contains a million timesas much water as a tiny cloud droplet. The growth of a cloud droplet toa size large enough to fall out is the cause of rain and other forms ofprecipitation. This important growth process is called"coalescence."

86. What is the main topic of the passage?

A) The mechanics of rain.

B) The climate of North America.

C) How gravity affects air current.

D) Types of clouds.

87. The word "minute"in Line 5 is closest in meaning to which for the

following?

A) Second. B) Tiny. C) Smooth. D) Predictable.

88. Why don't all ice crystals in clouds immediately fall to Earth?

A) They are balanced by the pressure of rain droplets.

B) The effect of gravity at high altitude is random.

C) They are kept in the sky by air currents.

D) They are moving about without fixed directions.

89. What can be inferred about drops of water larger than 1/125 inch

in diameter?

A) They never occur.

B) They are not affected by the force of gravity.

C) In still air they would fall to earth.

D) In moving air they fall at a speed of thirty-two miles per hour.

90. In this passage, what does the term "coalescence" (in Paragraph 2)refer to?

A) The gathering of small clouds to form larger clouds.

B) The growth of droplets.

C) The fall of raindrops and other precipitation.

D) The movement of dust particles in the sunlight.

大学英语四级模拟试题四(附含答案解析)

大学英语四级模拟题四 Part One Reading Comprehension (2’×10 = 20’) Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre. Passage One Air pollution can spread from city to city. It even spreads from one country to another. Some northern European countries have had “black snow”from pollutants that have traveled through the air from other countries and have fallen with the snow. So air pollution is really a global problem. Air pollution can kill babies, older people, and those who have respiratory(呼吸的)diseases. As found in cities, air pollution increases the risks of certain lung diseases. Air pollution can cause both airplane and car accidents because it cuts down visibility (能见度). There are other possible health dangers from air pollution that we don’t know much about. For example, scientists are trying to find out whether chemicals that reach us from the air may cause changes in our cells. These changes might cause babies to be born with serious birth defects. Scientists are trying to learn how all the many chemicals are apt(易于的)to take into our bodies from air, water, food, and even medicines act together to affect our health and the way our bodies work. That is another reason why it is so important to begin to control pollution now instead of waiting until we learn all the answers. Air pollution costs us a lot of money. It corrodes(腐蚀)our buildings. It damages farm crops and forests. It has a destructive effect on our works of art. The cost of all this damage to our government is great. It would be much more worthwhile, both for us and for the government, to spend our tax dollars on air pollution control. 1. Air pollution may lead to airplane accidents because . A. it may cause pilots to be ill B. engines may fail from the air-borne dirt C. visibility is reduced D. it brings a lot of black snow 2. Scientists are trying to find a link between pollution and . A. intelligence levels B. birth problems C. man’s behavior D. the nervous system 3. Scientists have not yet determined . A. all of the effects of pollution on the human body B. how pollution can be controlled successfully C. when the atmosphere first became polluted D. how some snow becomes black 4. The author suggests that before air pollution becomes more serious, . A. factories will be forced to stop operating B. buildings should be protected C. the earth will begin to grow colder D. more money should be spent to solve the problem 5. We can conclude that . A. civilization may be ruined if pollution is not controlled B. pollution is more serious in Europe than it is in America C. most people do not know that pollution is a serious problem D. we should learn all the answers before we begin to control pollution Passage Two Stiletto heels could be banned from the workplace because of health and safety reasons, according to British Trade Union bosses. The Trade Union Congress, predominantly male, has proposed a motion arguing that high heels are disrespectful to women while they also contribute to long term injuries. They propose instead that women wear “sensible shoes”with an inch heel limit in an attempt to avoid future foot and back pain as well as injuries. The motion is due to be debated at next month’s conference. The motion states: “Congress believes high heels may look glamorous on the Hollywood catwalks but are completely in appropriate for the day-to-day working environment. Feet bear the burden of daily life, and for many workers prolonged standing, badly fitted footwear, and in particular high heels can be a hazard. Around two million days a year are lost through sickness as a result of lower limb disorders. Wearing high heels can cause long-term foot problems and also serious foot, knee and back pain and damaged joints. Many employers in the retail sector force women workers to wear high heels as part of their dress code. More must be done to raise awareness of this problem so that women workers and their feet are protected.” Nadline Dorries, the Tory Member of Parliament, however criticized the motion and said the extra height heels give women can help them when in the workplace. “I’m 5ft 3in and need every inch of my Christian Louboutin heels to look my male colleagues in the eye,”she said. “If high heels were banned in Westminster, no one would be able to find me. The Trade Union leaders need to get real, stop using obvious sexist tactics by discussing women’s

Calculate for a moment what could be done with even a part of those hours. Five thousand hours, I am told, are what a typical college undergraduate spends working on a bachelor's degree. In 10,000 hours you could have learned enough to become an astronomer or engineer. You could have learned several languages fluently. If it appealed to you, you could be reading Homer in the original Greek or Dostoyevsky in Russian. If it didn't, you could have walked around the world and written a book about it. The trouble with television is that it discourages concentration. Almost anything interesting and rewarding in life requires some constructive, consistently applied effort. The dullest, the least gifted of us can achieve things that seem miraculous to those who never concentrate on anything. But Television encourages us to apply no effort. It sells us instant gratification(满意). It diverts us only to divert, to make the time pass without pain. Television's variety becomes a narcotic(麻醉的), nor a stimulus. Its serial, kaleidoscopic (万花筒般的)exposures force us to follow its lead. The viewer is on a perpetual guided tour: 30 minutes at the museum, 30 at the cathedral, 30 for a drink, then back on the bus to the next attraction—except on television., typically, the spans allotted arc on the order of minutes or seconds, and the chosen delights are more often car crashes and people killing one another. In short, a lot of television usurps(篡夺;侵占) one of the most precious of all human gifts, the ability to focus your attention yourself, rather than just passively surrender it. Capturing your attention—and holding it—is the prime motive of most television programming and enhances its role as a profitable advertising vehicle. Programmers live in constant fear of losing anyone's attention—anyone's. The surest way to avoid doing so is to keep everything brief, not to strain the attention of anyone but instead to provide constant stimulation through variety, novelty, action and movement. Quite
