大學(xué)英語四級題閱讀題及答案 1
Priscilla Ouchida’s “energy-efficient” house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $100,000, three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double-paned (雙層玻璃的) windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Priscilla’s eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness.
Experts finally traced the cause of her illness. The level of formaldehyde (甲醛) gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitchen cabinets and wall-to-wall carpeting.
The Ouchidas are victims of indoor air pollution, which is not given sufficient attention partly because of the nation’s drive to save energy. The problem itself isn’t new. “The indoor environment was dirty long before energy conservation came along,” says Moschandreas, a pollution scientist at Geomet Technologies in Maryland. “Energy conservation has tended to accentuate the situation in some cases.”
The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn’t worry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants generated in most households seldom build up to dangerous levels.
31. It can be learned from the passage that the Ouchidas’ house ________.
A) is well worth the money spent on its construction
B) is almost faultless from the point of energy conservation
C) failed to meet energy conservation standards
D) was designed and constructed in a scientific way
32. What made the Ouchidas’ new house a horrible dream?
A) Lack of fresh air.
B) Poor quality of building materials.
C) Gas leakage in the kitchen.
D) The newly painted walls.
33. The word “accentuate” (Line 4, Para. 3) most probably means “________”.
A) relieve
B) accelerate
C) worsen
D) improve
34. Why were cracks in old houses not a big concern?
A) Because indoor cleanliness was not emphasized.
B) Because energy used to be inexpensive.
C) Because environmental protection was given top priority.
D) Because they were technically unavoidable.
35. This passage is most probably taken from an article entitled “________”.
A) Energy Conservation
B) Houses Building Crisis
C) Air Pollution Indoors
D) Traps in Building Construction

Engineering students are supposed to be examples of practicality and rationality, but when it comes to my college education I am an idealist and a fool. In high school I wanted to be an electrical engineer and, of course, any sensible student with my aims would have chosen a college with a large engineering department, famous reputation and lots of good labs and research equipment. But that’s not what I did.
I chose to study engineering at a small liberal-arts (文科) university that doesn’t even offer a major in electrical engineering. Obviously, this was not a practical choice; I came here for more noble reasons. I wanted a broad education that would provide me with flexibility and a value system to guide me in my career. I wanted to open my eyes and expand my vision by interacting with people who weren’t studying science or engineering. My parents, teachers and other adults praised me for such a sensible choice. They told me I was wise and mature beyond my 18 years, and I believed them.
I headed off to college sure I was going to have an advantage over those students who went to big engineering “factories” where they didn’t care if you have values or were flexible. I was going to be a complete engineer: technical genius and sensitive humanist (人文學(xué)者) all in one.
Now I’m not so sure. Somewhere along the way my noble ideals crashed into reality, as all noble ideals eventually do. After three years of struggling to balance math, physics and engineering courses with liberal-arts courses, I have learned there are reasons why few engineering students try to reconcile (協(xié)調(diào)) engineering with liberal-arts courses in college.
The reality that has blocked my path to become the typical successful student is that engineering and the liberal arts simply don’t’ mix as easily as I assumed in high school. Individually they shape a person in very different ways; together they threaten to confuse. The struggle to reconcile the two fields of study is difficult.
26. The author chose to study engineering at a small liberal-arts university because he ________.
A) wanted to be an example of practicality and rationality
B) intended to be a combination of engineer and humanist
C) wanted to coordinate engineering with liberal-arts courses in college
D) intended to be a sensible student with noble ideals
27. According to the author, by interacting with people who study liberal arts, engineering students can ________.
A) balance engineering and the liberal arts
B) receive guidance in their careers
C) become noble idealists
D) broaden their horizons
28. In the eyes of the author, a successful engineering student is expected ________.
A) to have an excellent academic record
B) to be wise and mature
C) to be imaginative with a value system to guide him
D) to be a technical genius with a wide vision
29. The author’s experience shows that he was ________.
A) creative
B) ambitious
C) unrealistic
D) irrational
30. The word “they” in “...together they threaten to confuse.” (Line 3, Para. 5) refers to ________.
A) engineering and the liberal arts
B) reality and noble ideals
C) flexibility and a value system
D) practicality and rationality

Section B
Directions: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.
Resilience Is About How You Recharge, Not How You Endure
[A] As constant travelers and parents of a 2-year-old, we sometimes fantasize about how much work we can do when one of us gets on a plane, undistracted by phones, friends, or movies. We race to get all our ground work done: packing, going through security, doing a last-minute work call, calling each other, then boarding the plane. Then, when we try to have that amazing work session in flight, we get nothing done. Even worse, after refreshing our email or reading the same studies over and over, we are too exhausted when we land to soldier on with (繼續(xù)處理) the emails that have inevitably still piled up.
[B] Why should flying deplete us? We’re just sitting there doing nothing. Why can’t we be tougher, more resilient (有復(fù)原力的) and determined in our work so we can accomplish all of the goals we set for ourselves? Based on our current research, we have come to realize that the problem is not our hectic schedule or the plane travel itself; the problem comes from a misconception of what it means to be resilient, and the resulting impact of overworking.
[C] We often take a militaristic, “tough” approach to resilience and determination like a Marine pulling himself through the mud, a boxer going one more round, or a football player picking himself up off the ground for one more play. We believe that the longer we tough it out, the tougher we are, and therefore the more successful we will be. However, this entire conception is scientifically inaccurate.
[D] The very lack of a recovery period is dramatically holding back our collective ability to be resilient and successful. Research has found that there is a direct correlation between lack of recovery and increased incidence of health and safety problems. And lack of recovery—whether by disrupting sleep with thoughts of work or having continuous cognitive arousal by watching our phones—is costing our companies $62 billion a year in lost productivity.
[E] And just because work stops, it doesn’t mean we are recovering. We “stop” work sometimes at 5pm, but then we spend the night wrestling with solutions to work problems, talking about our work over dinner, and falling asleep thinking about how much work we’ll do tomorrow. In a study just released, researchers from Norway found that 7.8% of Norwegians have become workaholics(工作狂). The scientists cite a definition of “workaholism” as “being overly concerned about work, driven by an uncontrollable work motivation, and investing so much time and effort in work that it impairs other important life areas.”
[F] We believe that the number of people who fit that definition includes the majority of American workers, which prompted us to begin a study of workaholism in the U.S. Our study will use a large corporate dataset from a major medical company to examine how technology extends our working hours and thus interferes with necessary cognitive recovery, resulting in huge health care costs and turnover costs for employers.
[G] The misconception of resilience is often bred from an early age. Parents trying to teach their children resilience might celebrate a high school student staying up until 3am to finish a science fair project. What a distortion of resilience! A resilient child is a well-rested one. When an exhausted student goes to school, he risks hurting everyone on the road with his impaired driving; he doesn’t have the cognitive resources to do well on his English test; he has lower self-control with his friends; and at home, he is moody with his parents. Overwork and exhaustion are the opposite of resilience and the bad habits we acquire when we’re young only magnify when we hit the workforce.
[H] As Jim Loehr and Tony Schwartz have written, if you have too much time in the performance zone, you need more time in the recovery zone, otherwise you risk burnout. Gathering your resources to “try hard” requires burning energy in order to overcome your currently low arousal level. It also worsens exhaustion. Thus the more imbalanced we become due to overworking, the more value there is in activities that allow us to return to a state of balance. The value of a recovery period rises in proportion to the amount of work required of us.
[I] So how do we recover and build resilience? Most people assume that if you stop doing a task like answering emails or writing a paper, your brain will naturally recover, so that when you start again later in the day or the next morning, you’ll have your energy back. But surely everyone reading this has had times when you lie in bed for hours, unable to fall asleep because your brain is thinking about work. If you lie in bed for eight hours, you may have rested, but you can still feel exhausted the next day. That’s because rest and recovery are not the same thing.
[J] If you’re trying to build resilience at work, you need adequate internal and external recovery periods. As researchers Zijlstra, Cropley and Rydstedt write in their 2014 paper: “Internal recovery refers to the shorter periods of relaxation that take place within the frames of the work day or the work setting in the form of short scheduled or unscheduled breaks, by shifting attention or changing to other work tasks when the mental or physical resources required for the initial task are temporarily depleted or exhausted. External recovery refers to actions that take place outside of work—e.g. in the free time between the work days, and during weekends, holidays or vacations.” If after work you lie around on your bed and get irritated by political commentary on your phone or get stressed thinking about decisions about how to renovate your home, your brain has not received a break from high mental arousal states. Our brains need a rest as much as our bodies do.
[K] If you really want to build resilience, you can start by strategically stopping. Give yourself the resources to be tough by creating internal and external recovery periods. Amy Blankson describes how to strategically stop during the day by using technology to control overworking. She suggests downloading the Instant or Moment apps to see how many times you turn on your phone each day. You can also use apps like Offtime or Unplugged to create tech free zones by strategically scheduling automatic airplane modes. The average person turns on their phone 150 times every day. If every distraction took only 1 minute, that would account for 2.5 hours a day.
[L] In addition, you can take a cognitive break every 90 minutes to charge your batteries. Try to not have lunch at your desk, but instead spend time outside or with your friends—not talking about work. Take all of your paid time off, which not only gives you recovery periods, but raises your productivity and likelihood of promotion.
[M] As for us, we’ve started using our plane time as a work-free zone, and thus time to dip into the recovery phase. The results have been fantastic. We are usually tired already by the time we get on a plane, and the crowded space and unstable internet connection make work more challenging. Now, instead of swimming upstream, we relax, sleep, watch movies, or listen to music. And when we get off the plane, instead of being depleted, we feel recovered and ready to return to the performance zone.
36. It has been found that inadequate recovery often leads to poor health and accidents.
37. Mental relaxation is much needed, just as physical relaxation is.
38. Adequate rest not only helps one recover, but also increases one’s work efficiency.
39. The author always has a hectic time before taking a flight.
40. Recovery may not take place even if one seems to have stopped working.
41. It is advised that technology be used to prevent people from overworking.
42. Contrary to popular belief, rest does not equal recovery.
43. The author has come to see that his problem results from a misunderstanding of the meaning of resilience.
44. People’s distorted view about resilience may have developed from their upbringing.
45. People tend to think the more determined they are, the greater their success will be.

大學(xué)英語四級題閱讀題及答案 4
Questions 31 to 35 are based on the following passage:
"Welcome to the U.S.A.! Major credit cards are accepted!"
By the millions they are coming no longer the tired, the poor, the wretched masses longing for a better living. These are the wealthy. "We dont have a budget," says a biologist from Brazil, as she walks with two companions through New York Citys South Street." We just use our credit cards."
The US has long been one of the worlds most popular tourist destinations, but this year has been exceptional. First, there was the World Cup, which drew thousands from every corner of the globe; then came the weakening of the US dollar against major currencies. Now the US, still the worlds superpower, can also claim to be the worlds bargain basement(廉價商品部). Nobody undersells America these days on just about everything, from consumer electronics to fashion clothes to tennis rackets. Bottom retail prices anywhere from 30 % to 70% lower than those in Europe and Asia have attracted some 47 million visitors, who are expected to leave behind $ 79 billion in 1994. Thats up from $74 billion the year before.
True, not everyone comes just for bargains. There remains an undeniable fascination in the rest of the world with all things American, nourished by Hollywood films and US television series. But shopping the USA is proving irresistible. Every week thousands arrive with empty suitcases ready to be filled; some even rent an additional hotel room to hold their purchases. The buying binge(無節(jié)制)has become as important as watching Old Faithful Fountains erupt in Yellowstone Park or sunbathing on a beach in Florida.
The US has come at last to appreciate what other countries learned long ago: the pouring in of foreign tourists may not always be convenient, but it does put money in the bank. And with a trade deficit at about $130 billion and growing for the past 12 months, the US needs all the deposits it can get. Compared with American tourists abroad, visitors to the US stay longer and spend more money at each stop; an average of 12.2 night and $ 1624 a traveler versus the Americans four nights and $298.
31. From what the Brazilian biologist says, we know that tourists like her ____.
A) are reluctant to carry cash with them
B) simply don t care how much they spend
C) are not good at planning their expenditure
D) often spend more money than they can afford
32.The reason why 1994 was exceptional is that ____.
A) it saw an unusually large number of tourists to the US
B) it witnessed a drop in the number of tourists to the US
C) tourism was hardly affected by the weakening of the US dollar that year
D) Tourists came to the US for sightseeing rather than for bargains that year
33.By saying " nobody undersells America" (Underlined), the author means that ____.A) no other country underestimates the competitiveness of American productsB) nobody expects the Americans to cut the prices of their commodities
C) nobody restrains the selling of American goods
D) no other country sells at a lower price than America
34.Why does the author assert that all things American are fascinating to foreigners?A) Because they have gained much publicity through the American media
B) Because they represent the world s latest fashions
C) Because they embody the most sophisticated technology
D)Because they are available at all tourist destinations
35.From the passage we can conclude that the US has come to realize____.
A) the weakening of the US dollar can result in trade deficits
B) the lower the retail prices, the greater in profits
C) tourism can make great contributions to its economy
D) visitors to the US are wealthier than US tourists abroad

大學(xué)英語四級題閱讀題及答案 5
The future population will be older than today, and this in turn will change the patterns of social demands. However, Mexico will still be far from the "aging societies" that will most likely prevail (占優(yōu)勢 ) in the industrialized countries. In less than 25 years, the country will have to add almost as much infrastructure as it has already built up to now, simply to maintain services and production at the current levels. This will be a tremendous challenge, although a similar one was faced successfully in the recent past, when available infrastructure was doubled in two decades or so. It is no wonder that much has been said about the need to reduce or preferably halt Mexicos population control which is taken for granted as both good and necessary. It has also gained supporters in the developing world, and Mexico is no exception. But the arguments about population are complicated, as the following discussion illustrates.
Even if Mexicos population reaches 125 million by the year 2010, its population density is still smaller than the 1985 population density of some 50 countries. By international standards Mexico will still not be overpopulated by the year 2010. If wealth is generated by people, the more individuals there are, the greater the wealth that potentially could be generated. Why should Mexico control its population at density levels below those of the richer countries if more population represents the possibility of generating more wealth?
On the other hand, it is often pointed out that once sustainability(支撐力) limits are near or are reached, there are decreasing productivity gains (or,perhaps more accurately, increasing productive losses) , and people become a cost rather than an asset. If we assume that there are sustainability limits and that we are close to reaching these limits at a world level, then it is appropriate to check population growth.
21. According to the passage, the population argument is focused on_______.
A. whether more people are a property or a cost
B. whether Mexico should control its population growth or not
C. whether the density of population in Mexico is large or small
D. what the standard international sustainability limit is
22. Which of the following is TRUE according to the first paragraph?
A. Mexico has stepped into an aging society.
B. It is not necessary for Mexico to control its population.
C. Mexico population is younger than that of developed countries.
D. It is not necessary for Mexico to develop its infrastructure.
23. By "infrastructure"(Para. 2) the author means_______.
A. buildings
B. the basic framework of a country, such as schools, services, etc.
C. social demands
D. services and production
24. It may be inferred from the 3rd paragraph that_______.
A. it isnt necessary for Mexico to control its population growth
B. population is likely to grow at a slower pace than in the past
C. the more people there are, the greater the wealth people could generate
D. Mexico should control its population growth because she belongs to the developing countries
25. To check population growth is necessary when_______.
A. there are decreasing productivity gains
B. there are increasing productivity losses
C. we are close to reaching the sustainability limits at a world level
D. people become a cost

21. B 22. C 23. B 24. A 25. C
大學(xué)英語四級題閱讀題及答案 6
Not all sounds made by animals serve as language, and we have only to turn to that extraordinary discovery of echolocation (回聲定位) in bats to see a case in which the voice plays a strictly practical role.
To get a full appreciation of what this means we must turn first to some recent human inventions. Everyoneknows that if he shouts near a wall or a mountainside, an echo will come back. The further off this solid obstacle, the longer time it will take for the return of the echo. A sound made by tapping on the main body of a ship will be reflected from the sea bottom, and by measuring the time interval between the taps andthe receipt of the echoes the depth of the sea at that point can be calculated. So was born the echo-sounding equipment, now in general use in ships. Every solid object will reflect a sound, varying according to the size and nature of the object. A shoal of fish will do this. So it is a comparatively simple step fromlocating the sea bottom to locating a shoal of fish. With experience, and with improved equipment, it is now possible not only to locate fish but to tell if it is herring, cod, or other well-known fish, by the pattern of its echo.
A few years ago it was found that certain bats emit squeaks (吱吱聲) and by receiving ’he echoes they could locate and steer clear of obstacles--or locate flying insects on which they feed. This echolocation in bats is often compared with radar, the principle of which is similar.
練習(xí)題：
Choose correct answers to the question:
1.The main purpose of this passage is to ______.
A. describe that animals can make different sounds
B. prove that animals’ voices can play practical roles
C. inspire the readers to make more inventions
D. startle the readers with some shocking facts
2. The discovery of echolocation may help with all of the following EXCEPT

答案解析
1.[B] 主旨大意題。文章第1段就點(diǎn)明主題，明確指出以蝙蝠為例，動物發(fā)出的聲音有實(shí)際作用，只有B可以概括文章的這個寫作目的。
2.[C] 事實(shí)細(xì)節(jié)題。本題考査列舉處，可用排除法解答。A、B、C在文中都有相關(guān)提及。D利用第2段中的varying制造干擾。在原文中，指的是回聲因障礙物的不同而不同，而D偷換概念、曲解文意，D中的.varying為及物動詞，意為“改變”,顯然不可能是回聲定位的發(fā)現(xiàn)帶來的功效。
3.[C] 詞義推斷題。本題考查對shoal的詞義推測及代詞this的理解。依據(jù)第2段最后幾句話,可推測出a shoal of fish指的是“海里的一群魚”;this則是指上一句提到的“任何固體都可以反射聲音”，因此這句話表明一大群魚就能像一個固體一樣反射聲音。
4.[D] 推理判斷題。根據(jù)最后一段可知，蝙蝠發(fā)出吱吱聲可以探測障礙物的距離，而第2段也指出輕敲船體可測知海底的距離，因此在功能上,D與蝙蝠的吱吱聲相同。A中的human languages在文中未提到;B和C在文中各自的例子中充當(dāng)?shù)亩际钦系K物的角色，因此都不正確。
5.[D] 推理判斷題。文章先說動物的回聲定位功能,再說到回聲定位探測儀的發(fā)明,由此可見，是動物的某些能力啟發(fā)了人類的創(chuàng)造，因此只有D可從文中推測。文章并沒有從智力方面比較人類和動物，因此可以排除A 和B;盡管文章說到了蝙蝠和雷達(dá)的原理相似，但是C中的often一詞無據(jù)可循，且C的說法浮于表面，沒有說到重點(diǎn)，故排除。
