英语四级阅读模拟训练和答案

大学英语四级（阅读）模拟试卷3(题后含答案及解析) 题型有： 4. Reading Comprehension (Reading in Depth)Part IV Reading Comprehension (Reading in Depth) (25 minutes)Section BDirections: 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.Normally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice. For every course that he follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.1．Normally a student would attend at least______classes each week.A．36B．20C．12D．15正确答案：C解析：由文章第1段可知，每个学生每学期要上4到5门课，每门课每周有3节，由此可知学生每周要上12一15节课，因此一个学生每个星期至少要上12节课．故选C。

四级考试英语阅读模拟题及答案四级考试英语阅读模拟题(一)Newspapers often tell us of floods in some parts of the United States.Nearly every year on the great central drainages heavy rains and melting snow cause the waters to pour out the mountains and plains, to turn brooks into torrents, and to swell quiet streams into wild uncontrolled rivers. From Cairo to New Orleans, and from Pittsburgh to Paducah, the cry "River rising!" is a familiar yet fearful voice. . . When the rivers sometimes become too high or too swift to be controlled communities are flooded, families flee from their homes, croplands are washed out, and transportation comes to a halt. Hunger, disease, and death follow the wild waters.Although given less publicity, the agricultural damage done by the many smaller, more frequent floods usually far e某ceeds the losses caused by the very grand ones. In the Central States, ditches and drains cause the flows from spring rains and melting snow to run far more rapidly than in the days before white men settled on the land. Once, e某cess spring flood waters emptied into lakes and swampy lands, there to be detained for slow release into stream and rivers. Now, systematic drainage has actually eliminated these natural reservoirs.In the more rolling sections of the East, spring runoff was formerly absorbed and held temporarily in the porous soils beneath the unbroken e某panse of forest. When large areas were converted to farm use, removal of the forest and the practice of up-and-down hill plowing deprived the soils of much of their ability to catch and store water.The effects of eliminating the natural forest cover are shown in the gullied farm lands and widened stream channels found in some densely settled areas. Partly because the stream channels are more or less filled with material washed down from the uplands, and partly because storm runoff has increased, the channels are today no longer able to carry all the flow from heavy rains. This e某plains why the streams overtop banks far more often than in the days before settlement.26. The best title for the selection would be______.A. River Rising! River Rising!B. Forests and FloodsC. Flooding in the U. S.D. The Results of Flooding27. All of the following cause floods E某CEPT______.A. heavy rainB. melting snowC. increasing storm runoffD. porous soil28. The author states that______.A. lakes and swamps once acted like natural reservoirsB. up-and-down hill plowing catches and stores waterC. stream channels are the best carriers of waterD. floods are easily prevented and controlled29. According to the selection, streams overtop their bankspartly because______.A. material from higher land is washed into themB. ditches and drains lead into themC. rivers become too swiftD. snow melts more rapidly nowadays30. The floods which are given most publicity______.A. cause no damageB. cause the most damageC. cause less agricultural damage than the many smaller, more frequent floodsD. far e某ceed the smaller, more frequent floods in agricultural loss四级考试英语阅读模拟题答案26.

C四级考试英语阅读模拟题(二)When companies consider their benefits mi某.coverage for medical care is often top.of-mind.Yet there may be another,even more powerful concern driving employee coverage preferences：vision care.Roughly 75%of adults in the United States require some type of vision correction.and 84 percent of adults believe that vision benefits are somewhat or very important to them.As a result.vision assistance is moving higher and higher on the list of sought.after employee benefits.What’s driving the trend?One factor is the increasing power of eye e某aminations to detect systemic illness.In addition to identifying nearsightedness，farsightedness and astigmatism，routine eye e某anls now play a role in diagnosing conditions such as diabetes，brain aneurysms(脑动脉瘤)，liver disease and stroke risk. Early identification，in turn，translates into markedly lower e某penditures for employers.In 2022，eye problems will cost companies an estimated$8 billion in reduced productivity.Making sure employees get the right eye care helps employers reduce these losses.At the same time，it boosts their ability to retain loyal workers.So what’s the best way to get patients into the e某am chair?One way is to provide a vision plan that lowers out-of-pocket(自已付费的)e某penses.Indeed，research shows that out-of-pocket e某pense--not premiums--is the number-one factor employees consider when choosing a-vision plan.“And that’s just smart.〞says independent insurance broker Shannon Enders. “Premiums make up only about 30 percent of total out.of-pocket e某penses.So it pays to100k beyond the premium and see the real cost of a plan.〞A study conducted by Service E某cellence Group Inc.，a leading market research company,shows how the right vision insurance plan can result in across—the-board(全面的)savings for employees.The study compared the prices customers with different insurance plans paid for the same popular pair of eyeglasses at independent doctors and retail chains.It found that customers with insurance plans that were most successful at keeping out-of-pocket e某penses low saved hundreds of dollars.With eyeglasses becoming as much of a fashion accessory(装饰品)as a vision aid，forward-thinking companies are beginning to takenote.Enders says more of his clients are saying yes to vision care plans.“Employees care about their eyes，〞he says.“And offering benefits packages with the features employees care most about will become an even more important corporate strategy going forward.〞61.What is the meaning of the last sentence of paragraph one?A.Vision assistance is listed on the list of popular worker interests.B.Vision assistance is becoming more and more popular among employees。

英语四级阅读模拟试题：【原文】As she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table.

英语四级阅读理解模拟练习及答案详解Passage OneQuestions 57 to 61 are based on the following passage.There is a new type of small advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among “situations vacant”, although it does not offer anyone a job, and sometimes it appears among “situations wanted”, although it is not placed by someone looking for a job, either. What it does is to offer help in applying for a job.“Contact us before writing your application”, or “Make use of our long experience in preparing your curriculum vitae or job history”, is how it is usually expressed. The growth and apparent success of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae (or job history), with the suggestion that it may now qualify as an art form in its own right.There was a time when job seekers simply wrote letters of application. “Just put down your name, address, age and whether you have passed any exams”, was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained, everything else could and should be saved for the interview. And in those days of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest.Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. “Your search is over. I am the person you are looking for”, was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job interview.There is no doubt, however, that it is increasing number of applicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.57. The new type of advertisement which is appearing in newspaper columns .A) informs job hunters of the opportunities availableB) promises to offer useful advice to those looking for employmentC) divides available jobs into various typesD) informs employers of the people available for work58. Nowadays a demand for this specialized type of service has been created because .A) there is a lack of jobs available for artistic peopleB) there are so many top?level jobs availableC) there are so many people out of workD) the job history is considered to be a work of art59. In the past it was expected that first job hunters would .A) write an initial letter giving their life historyB) pass some exams before applying for a jobC) have no qualifications other than being able to read and writeD) keep any detailed information until they obtained an interview60. Later, as one went on to apply for more important jobs, one was advised to include in the letter .A) something that would distinguish one from other applicantsB) hinted information about the personality of the applicantC) ones advantages over others in applying for the jobD) an occasional trick with the aggressive approach61. The curriculum vitae has become such an important document because .A) there has been an increase in the number of jobs advertisedB) there has been an increase in the number of applicants with degreesC) jobs are becoming much more complicated nowadaysD) the other processes of applying for jobs are more complicatedPassage TwoQuestions 62 to 66 are based on the following passage.In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartments. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent —controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.Some theorists argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low—paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.Economic theory predicts the results of economic decisions such as decisions about farm production, rent control, and the minimum wage. The predictions may be correct only if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.62. There is the possibility that setting maximum rent may .A) cause a shortage of apartmentsB) worry those who rent apartments as homesC) increase the profits of landlordsD) encourage landlords to invest in building apartment63. According to the critics, rent control .A) will always benefit those who rent apartmentsB) is unnecessaryC) will bring negative effects in the long runD) is necessary under all circumstances64. The problem of unemployment will arise .A) if the minimum wage is set too highB) if the minimum wage is set too lowC) if the workers are unskilledD) if the maximum wage is set65. The passage tells us .A) the relationship between supply and demandB) the possible results of government controlsC) the necessity of government controlD) the urgency of getting rid of government controls66. Which of the following statements is NOT true?A) The results of economic decisions can not always be predicted.B) Minimum wage can not always protect employees.C) Economic theory can predict the results of economic decisions if other factors are not changing.D) Economic decisions should not be based on economic theory.答案详解：57. B细节理解题。

一．Baekeland and Hartmann report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.In general, these “short sleeps” appeared ambitious, active, energetic, cheerful, conformist(不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or workers full-or part-time while going to school. And many of them had a strong urge to appear “normal” or “acceptable” to their friends and associates.When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.The sleep patterns of the “short sleepers” were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic(疯人).The “long sleepers” were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the “short sleepers.”Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly states that sleep wasan escape from their daily problems.1. According to the report,______.A) many short sleepers need less sleep by natureB) many short sleepers are obliged to reduce their nightly sleep time because they are busy with their workC) long sleepers sleep a longer period of time during the dayD) many long sleepers preserve their sleeping habit formed during their childhood2. Many “short sleepers” are likely to hold the view that _____.A) sleep is a withdrawal from the realityB) sleep interferes with their sound judgementC) sleep is the least expensive item on their routine programD) sleep is the best way to deal with psychological troubles3. It is stated in the third paragraph that short sleepers _____.A) are ideally vigorous even under the pressures of lifeB) often neglect the consequences of inadequate sleepC) do not know how to relax properlyD) are more unlikely to run into mental problems4. When sometimes they cannot enjoy adequate sleep, the long sleepers might ____.A) appear disturbedB) become energeticC) feel dissatisfiedD) be extremely depressed5. Which of the following is Not included in the passage?A) If one sleeps inadequately, his performance suffers and his memory is weakenedB) The sleep patterns of short sleepers are exactly the sane as those shown by many mental patientsC) Long and short sleepers differ in their attitudes towards sleepD) Short sleepers would be better off with more rest答案：DCBAB贝克尔和哈特曼报道说，“睡眠少的人”在未进入少年期之前，其正常睡眠时间大致与所需要的时间差不多。

全国英语四级阅读模拟习题附答案全国英语四级阅读模拟习题附答案在当今这个学习英语风潮盛行的社会，英语似乎已经成为了我们生活中不可或缺的一局部，下面是为大家搜索的英语四级辅导练习，希望能给大家带来帮助!I’m usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded that today’s children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children ages 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago.Why are America’s kids so stressed? The report cites two main causes: increasing physical isolation—brought on by high divorce rates and less involvement in munity, among other things—and a growing perception that the world is a more dangerous place.Given that we can’t turn the clock back, adults can still do plenty to help the next generation cope.At the top of the list is nurturing (培育) a better appreciation of the limits of individualism. No child is anisland. Strengthening social ties helps build munities and protect individuals against stress.To help kids build stronger connections with others, you can pull the plug on TVs and puters. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep.Limit the amount of virtual (虚拟的) violence your children are exposed to. It’s not just video games andmovies; children see a lot of murder and crime on the local news.Keep your expectations for your children reasonable. Many highly suessful people never attended Harvard or Yale.Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a goodmodelfor your kids. Sometimes anxiety is unavoidable. But it doesn’t have to ruin your life.1.The author thinks that the conclusions of any research about people’s state of mind are .A. surprisingB. confusingC. illogicalD. questionable2. What does the author mean when he says, “we can’t turn the clock back” (Line 1, Para. 3)?A. It’s impossible to slow down the pace of change.B. The social reality children are facing cannot be changed.C. Lessons learned from the past should not be forgotten.D. It’s impossible to forget the past.3.Aording to an analysis, pared with normal children today, children treated as mentallyill 50 years ago .A. were less isolated physicallyB. were probably less self-centeredC. probably suffered less from anxietyD. were considered less individualistic4.The first and most important thing parents should do to help their children isA. to provide them with a safer environmentB. to lower their expectations for themC. to get them more involved sociallyD. to set a good model for them to follow5.What conclusion can be drawn from the passage?A. Anxiety, though unavoidable, can be coped with.B. Children’s anxiety has been enormously exaggerated.C. Children’s anxiety can be eliminated with more parental care.D. Anxiety, if properly controlled, may help children bee mature.1.[D] 题目中的`people’s state of mind就是本文第1句中either happier or unhappier or more or less certain of themselves。

英语四级阅读理解模拟试题及答案Our quarrel with efficiency is not that it gets things done,but that it is a thief of time when it leaves us no leisure to enjoy ourselves, and that it strains our nerves when we try toget things done perfectly. In building bridges, American engineers calculate so finely and exactly as to make the twoends come together within one-tenth of an inch. But when twoChinese begin to dig a tunnel from both sides of a mountainboth come out on the other side. --The Chinese’s firm belief is that it doesn ’t matter so long as a tunnel is dug through, and ifwe have two instead of one, why, we have a double track toboot.The pace of modern industrial life forbids this kind of glorious and magnificent idling. But, worse than that, it imposes upon us a different conception of time as measuredby the clock and eventually turns the human being into a clock himself. (This sort of thing is bound to come to China, as is evident, for instance, in the case of a factory of twenty thousand worker. The luxurious prospect of twenty thousandworkers coming in at their own sweet pleasure at all hours is,of course, somewhat terrifying.)Nevertheless, such efficiency iswhat makes life so hard and full of excitement. A man who hasto be punctually at a certain place at five o ’clock has the whole afternoon from one to five ruined for him already. Every American adult is arranging his time on the pattern of the schoolboy - three o ’clock for this, five o ’ clock for that, six-thirty for change of dress, six-fifty for entering the taxi, andseven o ’clock for arriving at the destination. It just makes lifenot worth living.1.The writer objects to efficiency mainly on thegrounds that it ____.A) entitles us to too much leisure time B)urges us to get things done punctually C)deprives us of leisure timeD) imposes on us a perfect concept of time2.In the eyes of the author, the introduction ofindustrial life gives rise to ____.A) the excitement of lifeB) magnificent idling of timeC) more emphasis on efficiencyD) terrifying schoolboy3.The passage tells us ____.A)Chinese workers come to work when it is convenientB)all Americans are forced to be efficient against their willC)Chinese engineers are on better terms with the managementD)Americans ought not to work so hard for efficiency4.The author believes that relaxing the rule ofpunctuality in factories would lead to ____.A) great confusionB) increased production C)a hard and exciting lifeD) successful completion of a tunnel5.What is implied but NOT stated by the author is that____.A) every American is arranging his time in the pattern of a schoolboyB) every American is reluctant to be efficientC)every one should have some time to spend as he pleasesD) being punctual is an undesirable habit which should not be formed答案：1.C)deprives us of leisure time 对应原文第一句 but that it is a thief of time when it leaves us no leisure to enjoy ourselves.选项 A 是与作者想法完整相反的; 选项 B 虽有章可循 , 但要注意原文是it strains our nerves when we try to get things done perfectly, 而非it 直接 urges us to get things done punctually;选项 D 要看清 , 原文是 a different conception of time而非 a perfect concept of time.The2.C)more emphasis on efficiency 对应原文第二段第一句pace of modern industrial life forbids this kind of glorious and magnificent i dling.经过第一段能够看出,与efficiency对峙的是this kind of glorious and magnificent idling, 而 industrial life 又forbids, 自然说明 industrial life gives rise to more emphasis on efficiency.3.D)Americans ought not to work so hard for efficiency. 排除法 : A)Chinese workers come to work when it is convenient 不切合原文()中的内容 ; B)all Americans are forced to be efficient against their will 语气太重, 不是被逼迫讲究效率 , 也不是违反自己意向 , 不过为了适应工业社会; C)Chinese engineers are on better terms with the management不属于本文议论范围。

大学英语四级阅读模拟题及答案阅读1空调的危害Although many of us may feel air-conditioners bring relief from hot,humid or polluted outside air,they pose many potential health hazards.Much research has looked at how the movement of air inside a closed environment---such as an office building---can spread disease or expose people in the building to harmful chemicals.One of the more widely publicized dangers is that of Legionnaire’s disease,which was first recognized inthe1970s.This was found to have affected people in buildings with air-conditioning systems in which warmair pumped out of the system’cooling towers was somehow sucked back into the air intake(通风口),in mostcases due to poor design.The warm air,filled with bacteria,was combined with cooled,conditioned air andwas then circulated around various parts of the building. Studies showed that even people outside such buildings were at risk if they walked past air exhaust pipes.Large air-conditioning systems add water to the air they circulate by means of humidifiers(湿度调节器).Inolder systems,the water used for this process is kept in special reservoirs,the bottoms of which providebreeding grounds for bacteria which can find their way into the ventilation (通风)system.The risk to human health from this situation has been highlighted by the fact that the immune systems(免疫系统)of approximately half of workers in air-conditioned office buildings have developed the ability to fight off the organisms found at the bottom of system reservoirs. But chemicals called“biocides”are added to reservoirs to make them germ-free,and they are dangerous in their own right in sufficient quantities,as they often contain compounds strongly linked to cancers.Finally,it should be pointed out that the artificial climatic environment created byair-conditioners canalso affect us.In a natural environment,whether indoor or outdoor,there are small variations in temperature and humidity.Indeed,the human body has long been accustomed to these normal changes.In an air-conditioned living or working environment,however,body temperatures remain well under37℃,our normal temperature.This leads to a weakened immune system and thus greater exposure to diseases such as colds and flu.练习题：Choose correct answers to the question:1.What do we know about Legionnaire's disease from the passage?A.It was the most widely concerned office hazard.B.It can affect people both inside and outside the building.C.It happens only in air-conditioned office buildings.D.It does not develop in well-designed buildings.2.In the old air-conditioned systems,bacteria first develop______.A.in the reservoirsB.in the ventilation systemc.in the humidifiersD.in the air intake3.The fact that about half of workers developed the ability to fight off the bacteria may__.A.relieve people’s worry about the danger caused by the bacteriaB.help people find an effective way to get rid of the bacteriaC.reflect the serious danger brought by the bacteriaD.cause serious disease such as cancers to people4.The author most probably wants the readers to treat biocides with an attitude of_.A.cautionB.trustC.enthusiasmD.criticism5.The last paragraph implies that our immune system can be weakened when_•A.we live in an artificial climatic environmentB.there are variations in temperature and humidityC.our body temperatures often remain not high enoughD.we are often exposed to diseases such as colds and flu答案解析：1.[B]事实细节题。

英语四级考试阅读模拟题(一)Where do pesticides fit into the picture of environmental disease? We have seen that they now pollute soil,water and food, that they have the power to make our streams fishless and our gardens and woodlands silent and birdless. Man, however much he may like to pretend the contrary, is part of nature. Can he escape a pollution that is now so thoroughly distributed throughout our world: We know that even single exposures to these chemicals, if the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farmworkers, and others exposed to sufficient quantities of pesticides is very sad and should not occur. For the population as a whole, we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that invisibly pollute our world.Responsible public health officials have pointed out that the biological effects of chemicals are cumulative over long periods of time, and that the danger to individual may depend on the sum of the exposures received throughout his lifetime. For these veryreasons the danger is easily ignored. It is human nature to shake off what may seem to us a threat of future disaster. Men are naturally most impressed by diseases which have obvious signs, says a wise physician, Dr Rene Dubos, yet some of their worst enemies slowly approach them unnoticed.练习题：Choose correct answers to the question:1.Which of the following is closest in meaning to the sentence Manis part of nature (Para. 1, Lines 3-4)?A. Man appears indifferent to what happens in nature.B. Man acts as if he does not belong to nature.C. Man can avoid the effects of environmental pollution.D. Man can escape his responsibilities for environmental effects of pesticides?2. What is the authors attitude toward the environmental effects of pesticides?A. PessimisticB. IndifferentC. DefensiveD.
