下面是我给大家提供的大学四级的英语阅读理解题以及答案解析，有兴趣的朋友可以练习一下哦!
第一篇：
Merchant and passenger ships are generally required to have a life preserver for every person aboard and in many cases, a certain percentage of smaller sizes for children. According to United States requirements, life preservers must design, reversible capable of being quickly adjusted to fit the uninitiated indivial, and must be so designed as to support the wearer in the water in an upright or slightly backward position.
Sufficient buoyancy(浮力) to support the wearer should be retained by the life preserver after 48 hours in the water, and it should be reliable even after long period of storage. Thus it should be made of materials resistant to sunlight, gasoline, and oils, and it should be not easily set on fire.?The position in which the life preserver will support a person who jumps or falls into the water is most important, as is its tendency to turn the wearer in the water from a face-down position to an upright or slightly backward position, with his face clear of the water, even when the wearer is exhausted or unconscious.
The method of adjustment to the body should be simple, and self-evident to uninitiated persons even in the dark under the confused conditions, which follow a disaster. Thus, the life be reversible that it is nearly impossible to get it on wrong. Catches, straps, and ties should be kept to a minimum. In addition, the life preserver must be adjustable to the wide variety of shapes and sizes of wearers, since this greatly affects the position of floating and the self-righting qualities. A suitable life also be comfortable to wear at all times, in and out of the water, not so heavy as to encourage to take it off on shipboard while the ship is in danger, nor so burdensome that it hinders a person in the water while trying to swim.
1. The passage is mainly about____.
A) the uses of life preservers
B) the design of life preservers
C) the materials for life preservers
D) the buoyancy of life preservers
2. According to the passage, a life be first of all ____.
A) adjustable B) comfortable C) self-evident D) self-righting
3. United States Coast Guard does NOT require the life preserver to be made ____.
A) with as few strings as possible
B) capable of being worn on both sides
C) according to each wearer's size
D) comfortable and light to wear
4. By “the uninitiated indivial” (Para. 1, Line. 4) the author refers to the person ____.
A) who has not been instructed how to use a life preserver
B) who has a little experience in using a life preserver
C) who uses a life preserver without permission
D) who becomes nervous before a disaster
5. What would happen if a person were supported by the life preserver in a wrong position?
A) The waves would move him backwards.
B) The water would choke him.
C) He would immediately sink to the bottom.
D) He would be exhausted or unconscious.
第二篇：
The table before which we sit may be, as the scientist maintains, composed of dancing atoms, but it does not reveal itself to us as anything of the kind, and it is not with dancing atoms but a solid and motionless object that we live. So remote is this “real” table——and most of the other “realities” with which science deals——that it cannot be discussed in terms which have any human value, and though it may receive our purely intellectual credence it cannot be woven into the pattern of life as it is led, in contradistinction to life as we attempt it. Vibrations in the ether(以太) are so totally unlike the color, purple that the gulf between them cannot be bridged, and they are, to all intents and purposes，not one but two separate things of which the second and less “real” must be the most significant for us. And just as the sensation which has led us to attribute all objective reality to a non-existent thing which we called “purple”is more important for human life than the conception of vibrations of a certain frequency; so too the belief in God; however ill founded, has been more important in the life of man than the germ theory of true the latter may be.
We may, if we like, speak of consequence, as certain mystics love to do, of the different levels or orders of truth. We may adopt what is essentially a Platonistic (布拉图式的) trick of thought and insist upon postulating the existence of external realities which correspond to the needs and modes of human feeling and which, so we may insist, have their being in some part of the universe unreachable by science. But to do so is to make an unwarrantable assumption and to be guilty of the metaphysical fallacy of failing to distinguish between a truth of feeling and that other sort of truth which is described as “truth of correspondence” and it is better perhaps, at least for those of us who have grown up in thought, to steer clear of such confusions and to rest content with the admission that, though the universe with which science deals is the real universe, yet we do not and cannot have any but fleeting and imperfect contacts with it; that the most important part of our lives-our sensations, emotions, desires and aspirations-take place in a universe of illusions which science can attenuate or destroy, but which it is powerless to enrich.
1. The author suggests that in order to bridge the puzzling difference between scientific truth and the world of illusion, the reader should____.
A) try to rid himself of his world of illusion
B) accept his words as being one of illusion
C) apply the scientific method
D) learn to acknowledge both
2. Judging from the ideas and tone of the selection, one may reasonably guess that the author is ____.
A) a humanist B) a pantheist C) a nuclear physicist D) a doctor of medicine
3. According to this passage, a scientist would conceive of a “table” as being ____.
A) a solid motionless object
B) certain characteristic vibrations in “ether”
C) a form fixed in space and time
D) a mass of atoms in motion
4. The topic of this selection is____.
A) the distortion of reality by science
B) the confusion caused by emotions
C) Platonic and contemporary views of truth
D) the place of scientific truth in our lives
5. By “objective reality” (Last line, Para. 1) the author means____.
A) scientific reality
B) a symbolic existence
C) the viewer's experience
D) reality colored by emotion

：
It is doing something better than other people that makes us unique. Yet a surprising number of people still see indiviality as a surface thing. They wear bright clothes, dye their hair strange colors and decorate their skin with tattoos ***文身*** to make some kind of social statement.
The whole purpose of indiviality is excellence. The people who prehend the simple principle of being unique through performance make our entire political and economic system work. Those who invent, who improve, who know more about a subject than other people do, and who take something that doesn't work and make it work—these people are the very soul of capitali *** .
Charles Kettering didn't like the idea of cranking a car to make it start, so he invented the electric starter. Henry Ford figured out the assembly-line technique and made it possible to mass-proce automobiles. Lewis Waterman saw no need to go on dipping a pen into an inkwell, so he put the ink into the pen. George Westinghouse told the world how to stop a train, and Elisha Otis, inventor of the elevator, indirectly created the city skyline. These people understood that indiviali *** means working at the top of one's capacity.
Fortunately, enough Americans have been inspired to do something with their uniqueness that we have developed in less than three centuries from a frontier outpost into not only a country of freedom but a country strong enough to protect that freedom. These people prized the notions of indiviality and excellence above all things and thus kept the great machine functioning. The ones with the purple hair and the horrorable jewelry are just along for the ride, trying to be "different" and not knowing how to go about it.
1The student who earns A's on his report card has grasped the idea and has found the real meaning of indiviality. So has the youngster who has designed his own spaceship, who paints pictures of the world around him, or who can name all the states and their capitals. According to the author unique indivials are persons who______.
A. do something better than other people
B. know more about a subject than other people
C. excel others in work
D. all of the above
2、People who regard indiviality as a surface thing always do the following EXCEPT
A. wearing bright clothes B. coloring their hair
C. doing better than others D. decorating their skin with tattoos
3、Which is NOT TRUE according to the passage?
A. Henry Ford invented assembly-line technique.
B. Elisha Otis was the inventor of the lift
C. George Westinghouse created cranks.
D. Lewis Waterman put the ink into the pen.
4、It can be inferred from the passage that______.
A. the real secret to being unique lies in our excellent work
B. if we want to be different we'd gain more profit
C the student who earns A's on the report card has not grasped the real meaning ofindiviality
D. all Americans work miracles In the writer's opinion
5、who has understood the sense of indiviality?
A. The youngster who designed his own spaceship.
B. The youngster who painted worthy pictures.
C. The youngster who was interested in wearing strange clothes.
D. Both A and B.
答案：D C C A D
：
Anne Whitney, a sophomore ***大学二年级学生*** at Colorado State University, first had a problem taking tests when she began college. "I was always well prepared for my tests. Sometimes I studied for weeks before a test. Yet I would go in to take the test, only to find I could not answer the questions correctly. I would blank out because of nervousness and fear. I couldn't think of the answer. My low grades on the tests did not show what I knew to the teacher. " Another student in biology had similar experiences. He said, "My first chemistry test was very difficult. Then, on the second test, I sat down to take it, and I was so nervous that I was shaking. My hands were moving up and down so quickly that it was hard to hold my pencil. I knew the material and I knew the answers. Yet I couldn't even write them down!"
These two young students were experiencing something called test anxiety. Because a student worries and is uneasy about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the extreme tension and nervousness. Although poor grades are often a result of poor study habits, sometimes test anxiety causes the low grades. Recently, test anxiety has been recognized as a real problem, not just an excuse or a false explanation of lazy students.
Special university advising courses try to help students. In these courses, advisors try to help students by teaching them how to manage test anxiety. At some universities, students take tests to measure their anxiety. If the tests show ***heir anxiety is high, the students can take short courses to help them deal with ***heir tensions. These courses teach students how to relax their bodies. Students are trained to bee calm in very tense situations. By controlling their nervousness, they can let their minds work at ease. Learned information then es out without difficulty on a test.
An expert • at the University of California explains, " With almost all students, relaxation and less stress are felt after taking our program. Most of them experience better control ring their tests. Almost all have some improvement. With some, the improvement is very great. "
26. To "blank out" is probably______.
A. to be like a blanket B. to be sure of an answer
C. to be unable to think clearly D. to show knowledge to the teacher
27. Poor grades are usually the result of______.
A. poor sleeping habit B. laziness
C. lack of sleep D. inability to form good study habits
28. Test anxiety has been recognized as______.
A. an excuse for laziness B. the result of poor study habits
C. a real problem D. something that cannot be changed
29. To deal with this problem, students say they want to______.
A. take a short course on anxiety
B. read about anxiety
C. be able to manage or understand their anxiety
D. take tests to prove they are not anxious
30. A University of California advisor said______.
A. all students could overe the anxiety after taking a special test anxiety program
B. almost all students felt less stress after taking a University of California advising course
C. students found it difficult to improve even though they had taken a special test anxiety course
D. students found it easy to relax as soon as they entered a University of California advising course
26. C 27. D 28. C 29. A 30. B
㈣ 2019年6月大学英语四级阅读理解训练三篇
2019年6月大学英语四级阅配歼读理解培猛冲训练：梦
Of all the components of a good night's sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by thelate 1970s, neurologists had switched to thinking of them as just "mental noise"-the random byprocts of the neural repair work that goes on ring sleep. Now researchers suspect that dreams are part of the mind's emotional thermostat, regulating moods while the brain is "off line." And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better. "It's your dream," says Rosalind Cartwright, chair of psychologyat Chicago's Medical Center, "if you don't like it, change it."
he link between dreams and emotions shows up among the patients in Cartwright's clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated ring the day. Because our conscious mind is occupied with daily life we don't always think about the emotional significance of the day's events-until, it appears, we begin to dream.
知脊And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualizehow you would like it to end instead; the next time it occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.
At the end of the day, there's probably little reason to pay attention to our dreams at all unless they keep us from sleeping or "we wake up in panic," Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people's anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings.Sleep-or rather dream-on it and you'll feel better in the morning.
练习题：
Choose correct answers to the question:
1.By saying that “dreams are part of the mind's emotional thermostat," (Lines 4-5, Para. 1) the researchers mean that _______.
A.we can think logically in the dreams too
B.dreams can be brought under conscious control
C.dreams represent our unconscious desires and fears
D.dreams can help us keep our mood comparatively stable
2.What did Cartwright find in her clinic?
A.Most bad dreams were followed by happier ones.
B.Divorced couples usually have more bad dreams.
C.One’s dreaming process is related to his emotion.
D.People having negative feelings dream more often.
3.Cartwright believed with much practice，we can learn to _____.
A.control what dreams to dream
B.sleep well without any dreams
C.wake up in time to stop the bad dreams
D.identify what is upsetting about the dreams
4.The author points out that a person who has constant bad dreams should ______
A.learn to control his dreams
B.consult a doctor
C.sleep and dream on it
D.get rid of anxiety first
5.The author most probably thinks that controlling dreams is ______.
A.a good practice
B.a new discovery
C.helpful for everyone
D.not essential for everyone
参考答案及解析
1.[D] 词义理解题。在第1段第4句中，逗号后面的regulating moods是对emotional thermostat的功能进行解释说明，因此可以推断出选项D正确。
2.[C] 事实细节题。最具干扰的是选项A，因为其陈述与第2段第2句的陈述有点相似,但是，此长句说的是大多数人上半夜做噩梦，之后都会做好梦，而不是像选项A中所说大多数噩梦之后是好梦。而且，根据本段第1 句，很明显，选项C是这一句的近义替换。
3 [C] 推理判断题。本题考査对代词的理解。在第3段的最后一句中，代词it应指上文说到的控制噩梦，及时醒来等做法，因此只有选项C涉及了其中一个做法。选项A太泛了，选项B和D在文中并无提及。
4.[B] 事实细节题。本题考查根据构词法猜测词义的能力。解题关键是推断最后一段第3句中therapist的意义，在考纲词汇表中，therapy是“治疗”的意思，因此，therapist应该是专门负责某种治疗的医生，由此可见，选项B是对原文seek help from a therapist的近义替换。
5.[D] 观点态度题。根据最后一句可以推断作者认为如无必要，梦还是不要控制的好。做梦会让你早上感觉舒服一些，因此本题应选D。
2019年6月大学英语四级阅读理解训练：机器人跳舞
The dancers stand motionless at their position and the room grows silent. But as the music starts, they began to move, bending, turning and waving their fans gracefully as they perform. a traditional Japanese dance. Yoshihiro Kuroki watches in silence, occasionally making notes. But as the dance ends, he beams with happiness. The performance has been flawless.
There have been many performances of traditional Japanese dances over the centuries, but this one is unique,because it is performed not by human dancers but by robots. And the performance takes place not in a dance studio but in a laboratory of Sony Corp.'s Entertainment Robot Co. in Shinagawa, Japan, where Kuroki isgeneral manager. He is the mastermind behind a series of even more capable humanoid entertainment robots,starting with the Sony Dream Robot, or SDR, in 1997, up to the current QRIO in 2003.
These delightful machines are only 58 cm tall, about the size of a newborn infant, weigh about 7 kg, and move with 38 degrees of freedom, each with its own servomotor(辅助马达).
QRIO's predecessor, the SDR4X, announced in 2002, can walk, dance, sing, speak, recognize faces, and understand continuous speech. Each robot has two charge-coupled-device cameras to detect color and position andcan locate a colored ball, move toward it, and kick it into a goal. It also has contact sensors in severaljoints to avoid pinching real human fingers. Seeing the robot perform, it is difficult to remember that there is no sentience(知觉)behind those glass eyes.
练习题：
Choose correct answers to the question:
1.Which of the following is the most suitable title of this passage?
A.New Entertainment Robots Proced in Japan.
B.QRIO the Robot Dancers.
C.Robots Man's Best Friend.

2.Yoshihiro Kuroki ______.
A.is excited when the robots are performing a traditional Japanese dance
B.keeps silent because he is a little unsatisfied with the new proct

A.the first human-like entertainment robot developed by the Sony Corp
B.as capable as the QRIO of speaking,dancing,singing and walking
C.largest among all the entertainment robot developed by the Sony Corp
D.the first entertainment robot sold at the market by the Sony Corp
5.The robot can locate colored balls by mens of ____
A.a charge-coupled device
B.two cameras
C.two contacts sensors
D.a digital detector
参考答案及解析
1.[A] 主旨大意题。标题需要既全面又突出地概括文章的主题。本文先是描述“舞蹈演员”，然后揭晓这是些“机器人”(第2段第1句)，接着对Sony公司的一些机器人产品进行详细介绍。选项A比较全面地概括了文章内容。选项B、D只是涉及细节，不能全面地概括本文的内容。而C又过于笼统，不具有针对性。
2.[C] 事实细节题。选项C符合第2段最后一句“He is the mastermind behind a series of... robots...”。仔细阅读有关的细节信息会发现,第1段第3句可帮助否定选项A。第1段最后两句可帮助否定选项B。另外，根据第2段倒数第2句可否定选项D。
3.[D] 事实细节题。全文分四段，分别讨论机器人三方面的特点：第1段和第2段描述机器人舞蹈演员栩栩如生的表演，即选项A;第3段描写它们的外表，即选项B;第4段介绍它们巧妙的设计，即选项C;只有选项D是没有提到的，故为答案。
4.[A] 推理判断题。该句中的分词结构“starting with...”表明the Sony Dream Robot是第一个人形娱乐机器人，因此选项A正确。文章在最后一段的第1句提到两种能说话、跳舞的机器人，但没有提到SDR是否和它们一样，由此可否定选项B。在第3段讨论机器人大小的时候也没有提到SDR体型最大，因此选项C不正确。选项D在文中没有讨论到。
5.[B] 事实细节题。该句中“two…cameras to...”的结构表明这两个摄像头可以用于定位，所以选项B正确。选项A在该句中也有提到，但它只是摄像机的工作机制，而不是用于定位的装置。选项C在下一句提到，但与题干提到的定位功能无关。选项D在文中并未提及。
2019年6月大学英语四级阅读理解训练：决定婴儿性别
Henry III didn't know much about biology. He went through six wives back in the 1500s, looking for one whocould bear him a son. Scientists now know that it's the father's sperm, not the mother's egg, which determines whether a baby is a boy or a girl. And last week researchers at the Genetics and IVF Institute, a private fertility(生育能力)center in Virginia, announced a new technique that will allow parents to choose the sex of their baby-to-be, before it has even been conceived. The scientist used a tiny laser detector to measure the DNA in millions of sperm cells as they pass single file through a narrow tube, like cattle being herded through a corral(牲口栏). In a study published last week, "girl sperm," which has more DNA—the genetic material— in each cell, was collected, while "boy sperm" was discarded. And when purified girl sperm was used to impregnate(使受孕)a group of mothers, 15 of 17 resulting babies turned out to be girls.
The researchers say that "sex selection" can also double a mother's chance of having a son and can be usedto avoid genetic diseases that affect only one gender, such as hemophilia(血友病). But some experts, like New York University fertility specialist Dr. Jamie Grifo, worry that sex selection could lead to a kind ofin uteri(子宫)discrimination, especially in cultures where sons are considered superior to daughters. "It's valuing one gender' over another," Grifo says. "I don't think that's something we should be doing." So far, patients at the institute have been asking for both boys and girls, in order to "balance" their families. And some ethics experts say that's fine, as long as parents are just looking for a little gender variety. "If you have three boys, and you want a girl," says University of Texas reproctive-law professor John Robertson, "that's not gender bias at all."
练习题：
Choose correct answers to the question:
1.The DNA in the sperm cells can be measured ______.
A.in the same way how the cattle are herded
B.when they pass through a tube one behind the other
C.after they pass through a laser tube
D.when they are scanned by a laser detector all at a time
2.The gender of the baby is decided by ______.
A.the father's DNA
B.the mother's DNA
C.the father's sperm
D.the mother's egg
3.According to this passage, the practice of "sex selection" ______.
A.can help to prevent all genetic problems
B.is totally unacceptable to ethics experts
C.was already realized five hundred years ago
D.will benefit families with certain inheritable diseases
4.Girl sperm was preferred to boy sperm in the research most probably because____
A.girl sperm contains more genetic material
B.more mother want to have girl babies
C.girl sperm is healthier and more active
D.girl sperm is more easily purified
5.It can be concluded from the passage that author’s toward”sex selection”is____
A.negative
B.positive
C.neutral
D.favorable
参考答案及解析
1.[B] 推理判断题。解答本题的关键在于推断single file的意思。该句把精子通过试管的情形与牛群被赶入牲口圈的情形作对比，结合single一词本身的意思，可以推断single file是“一个接一个”的意思，只有选项B能表达这个意思，由此也可否定选项D。选项A最具干扰性，原句是把精子通过试管的情形比作牛群被赶人牲口圈的情形，而选项A说的是测定精子内DNA的方法与放牧的方法相同，显然选项A只是引用了原文的某些词语，但表达的意思与原文却截然不同。
2.[C] 事实细节题。第1段第3句which引导的非限制性定语从句修饰的是the father's sperm，而不是插入语the mother’s egg,因此选项C正确。
3.[D] 推理判断题。第2段第1句中的genetic暗示有些疾病是遗传的，即如选项D所述。第2段第1句同时表明选项A的说法是不全面的。选项B与第2段最后两句正好相反。第1段前两句说明选项C是错误的。
4.[A] 事实细节题。第1段倒数第2句中的由which引导的定语从句表明选项A的叙述正确。
5.[C] 观点态度题。文章第2段中作者给出了一些反对者和赞成者的观点，但是没有加以评论，可以看出作者的态度是中立的，故选项C正确。
㈤ 2019年大学英语四级考试阅读模拟试题及答案
2018年12月大学英语四级考试已经结束了，各位同学们发挥的怎么样呢?很多考生迫不及待的想要估算一下自己的分数，不要着急，考试栏目组我为大家带来了本次四级阅读真题答案，大家一起看看吧。
2019年大学英语四级考试阅读模拟试题：如何写作
Learning how to write is like taking a course in public speaking. I'd ask whether anyone in class had evertaken such a course. Always a few hands would go up.
"What did you learn in that course?" I'd ask.
"Well, the main thing was learning how to face an audience: not to be inhibited (拘谨)... not to be nervous. "
Exactly, when you take a course in public speaking nowadays, you don't hear much about grammar and vocabulary. Instead. you're taught how not to be afraid or embarrassed, how to speak without a prepared script. how to read out to the live audience before you. Public speaking is a matter of overcoming your long-standing nervous inhibitions.
The same is true of writing. The point of the whole thing is to overcome your nervous inhibitions, to break through the invisible barrier that separates you from the person who’ll read what you wrote. You must learn to sit in front of your typewriter of dictating machine and read out to the person at the other end of the line.
Of course, in public speaking with the audience right in front of you, the problem is easier. You can lookat them and talk to them directly. In writing, you 're alone. It needs an effort of your experience or imagination to take hold of that other person and talk to him or her. But that effort is necessary or at least it' s necessary until you've reached the point when you quite naturally and unconsciously "talk on paper".

1.[C] 事实细节题。原文第4段,特别是第4段的最后一句表明c为正确选项。本题稍具干扰性的是D，该选项中的live一词在第4段第2句末尾也有出现，但事实上D与该句的意思不相同。
2.[A] 事实细节题。本题考查对比处。第5段第1句表明下一句就是演讲和写作的相似之处，而A就是对该句的同义替换。其他选项并未按照题目的要求对比演讲与写作，只是说明了写作必须做的，因此都不正确。
3.[A] 推理判断题。本题考查对比处。结尾段对比了演讲和写作的不同之处，第1、2句和第3、4句形成了内在的对比关系，由此可推断写作比演讲更需要经验和努力，因此可确定A正确，而C不正确。虽然在这一段可找到effort和naturally等词，但原文并没有从是否要付出同样多的努力(B)或是否自然(D)等方面对比演讲与写作，因此B和D也不正确。
4.[D] 推理判断题。根据最后一句中的“在纸上说话”,可推断作者认为写作如在纸上作演讲一样，因此D正确。A中的Few students与事实不符;B中的speak with a script在文中未有提及;C中的separated by a barrier错误。
5.[D] 主旨大意题。文章的开头句就是全文的主题句，作者在前四段说明如何演讲，从第5段开始，作者转向说明如何写作,文章的结尾句对开头句做出了呼应。作者之所以将演讲和写作过程做比较是为了让自己的观点更容易、更生动地被读者明白和接受，因此本文的中心内容是围绕写作，而不是演讲。其余选项虽然文中都有提及，但只是各个具体的侧面内容，不能概括全文大意。
2019年大学英语四级考试阅读模拟试题：农业技术
Even plants can run a fever, especially when they're under attack by insects or
disease. But unlike humans, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago, adapting the infrared (红外线) scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide(杀虫剂) spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest(害虫) problems.
Even better, Paley's Remote Scanning Services Company could detect crop problems
before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night ,an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers".Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find.But with the renewed concern about pesticides on proce, and refinements in infrared scanning, Paley hopes to get back into operation.Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States, "says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks.remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.
这是一篇说明文。文章一开头就介绍了原用于军事和卫星的红外线扫描技术，如今被用在农业上。通过远距离测量植物的温度来判断农作物是否遭受虫害和疾病。在第二段中指出，物理学家帕里组建了帕里远红外扫描服务公司，来专门探测农业方面的情况。最后他的公司在三年后被迫关闭，主要是因为缺乏资金。另外，农民们也一时不能接受这种新技术。作者期待将来有一天可以解决财政困难，将这一新技术重新用到农业上去。

参考答案及解析
1、[答案及分析]：[C]。词组理解题。本文第一段的第一句话谈到：“Even plants can run fever...by insects or disease.”这就告诉了我们植物升高温度的原因。本句所问的也正是这个原因。因此，C正告诉了我们这一点，所以C是正确答案。
2、[答案及分析]：[D]词汇理解题。在第一段的原文中“The goal was to let farmers precisely target pesticide spraying...”其中的意思是“确定”(虫害发生的地方)”而答案D是说“要确定问题所在地区”，信息与本文相符，故D为正确答案;而A、B、C都与本文不符。
3、[答案及分析]：[A]。判断题。问农民通过何种方式可节省杀虫剂。在文章的第二段中谈到帕里远红外线扫描服务公司利用飞机上的远红外线扫描仪夜间在3000英尺的高度探测到庄稼的情况，然后可将这些情况提供给农民，农民可喷洒农药，这样只使用原来农药量的50%-70%就足够了。故答案A的信息与本文相符;而B、C、D均不正确。
4、[答案及分析]：[C]。词汇理解题。问远红外扫描技术用于农业上时遇到的阻力，原因何在。在本文最后段中指出：1984年，帕里公司被迫关闭的原因一资金缺乏。并呼吁说：“But only if Paley finds the financial backing which he failed to obtain 10years ago.”其中financial backing的意思与本题C的“financial support”相同。所以答案C正确。
5、[答案及分析]：[B]。正误判断题。问远红外扫描技术有可能重新用于农业，原因何在。在文章最后一段中说“But with the renewed concern...to get back into operation”由此可明显看出，B的信息与本文内容相符，所以答案B是正确的;而A、C、D都与本文不符。
㈥ 大学英语四级仔细阅读训练题和答案
下面是我整理的，希望对大家有帮助。
When one looks back upon the fifteen hundred years that are the life span of the English language, he should be able to notice a number of significant truths. The history of our language has always been a history of constant change—at times a slow, almost imperceptible change, at other times a violent collision between two languages. Our language has always been a living growing organi *** , it has never been static. Another significant truth that emerges from such a study is that language at all times has been the possession not of one class or group but of many. 『At one extreme it has been the property of the mon, ignorant folk, who have used it in the daily business of their living, much as they have used their animals or the kitchen pots and pans.』① At the other extreme it has been the treasure of those who have respected it as an instrument and a sign of civilization, and who have struggled by writing it down to give it some permanence, order, dignity, and if possible, a little beauty.
As we consider our changing language, we should note here two developments that are of special and immediate importance to us. One is that since the time of the Anglo-Saxons there has been an almost plete reversal of the different devices for showing the relationship of words in a sentence. Anglo-Saxon ***old English*** was a language of many inflections. Modern English has few inflections. We must now depend largely on word order and function words to convey the meanings that the older language did by means of changes in the forms of words. Function words, you should understand, are words such as prepositions, conjunctions, and a few others that are used primarily to show relationships among other words. A few inflections, however, have survived. And when some word inflections e into conflict with word order, there may be trouble for the users of the language, as we shall see later when we turn our attention to such maters as WHO or WHOM and ME or I. The second fact we must consider is that as language itself changes, our attitudes toward language forms change also. 『The eighteenth century, for example, proced from various sources a tendency to fix the language into patterns not always set in and grew, until at the present time there is a strong tendency to restudy and re-evaluate language practices in terms of the ways in which people speak and write.』②
1.In contrast to the earlier linguists, modern linguists tend to .
A. attempt to continue the standardization of the language
B. evaluate language practices in terms of current speech rather than standards or proper patterns
C. be more concerned about the improvement of the language than its *** ysis or history
D. be more aware of the rules of the language usage
2.Choose the appropriate meaning for the word “inflection” used in line 4 of paragraph 2.
A. Changes in the forms of words.
B. Changes in sentence structures.
C. Changes in spelling rules.
D. Words that have similar meanings.
3.Which of the following statements is not mentioned in the passage? A. It is generally believed that the year 1500 can be set as the beginning of the modern English language.
B. Some other languages had great influence on the English language at some stages of its development.
C. The English language has been and still in a state of relatively constant change.
D. Many classes or groups have contributed to the development of the English language.
4. The author of these paragraphs is probably a***an*** .
A. historian B. philosopher C. anthropologist D. linguist
5.Which of the following can be best used as the title of the passage? A. The history of the English language.
B. Our changing attitude towards the English language.
C. Our changing language.
D. Some characteristics of modern English.

长难句解析
①【解析】“who”引导非限制性定语从句，修饰“the mon, ignorant folk”。“much as”引导状语从句。“kitchen pots and pans”意为“锅碗瓢盆”。【译文】一方面它是那些普通人甚至无知民众的财产，他们每天都像使唤他们的牲畜和锅碗瓢盆一样用着语言。
②【解析】 此句为一个复合倒装句。“until”引导一个并列句，前一句的主语是“a tendency”，“to fix the language into patterns not always set in and grew”作“tendency”的定语，第二句的主语也是“a tendency”，
“to”后面的句子作“tendency”的定语，“in which”引导的定语从句修饰“ways”。 【译文】例如在18世纪一种产生于各种来源的趋势把语言固定在一个不常使用和不利于语言发展的模式中，而到了当今，主流是要反复研究、评价人们说话、写作中的语言实践。
答案与详解
【短文大意】本文主要讲述英语演变过程的一些特点，指出了古英语与现代英语的不同，以及语言学家对待语言形式的态度的变化。
1.B细节题。根据题干回原文中定位，阅读文章时注意首末段及各段开头的句子，这往往都是考点所在。这篇文章讲的主要是英语语言演变的一些特点，指出了古英语与现代英语的不同，以及语言学家态度的转变。本题问的正是现代语言学家与早期语言学家不同的倾向。根据文章末尾The eighteenth century, for example, proced from various sources a tendency to fix the language into patterns not always set in and grew, until at the present time there is a strong tendency to restudy and re-evaluate language practices in terms of the ways in which people speak and write. 现代语言学家倾向于根据人们说和写的方式评价语言实践，而不是像早期的语言学家根据一定的模式评价语言。选项B符合文章的意思。
2.A词汇题。要根据上下文的资讯判断单词的意思。文章在第二段中间再次提到inflection时说，A few inflections, however, have survived. 后面文章又举了WHO/WHOM和ME/I为例说明inflection，这是一篇关于语言学的文章，从例子可以看出inflection的意思应该是“单词的变形”，选项A正确。
3.A细节题。根据文章的内容，选项A“普遍认为1500年是现代英语的起点”在文章中没有提及，故为正确答案。文章第二句说The history of our language has always been a history of constant change - at times a slow, almost imperceptible change, at other times a violent collision between two languages. 我们语言的历史是一个不断变化的历史——在一些时间里缓慢得几乎难以察觉，在另一些时间里则是两种语言的激烈碰撞。由此可以推断一些其他的语言对英语的发展有重大影响，选项B符合文章的意思。
4.D词汇题。此题考查考生的推测能力和词汇量，文章讲述的是英国语言演进的具体细节，最适当的答案应该是D。作者很可能是一位语言学家。A答案***历史学家***和C答案***人类学家***也可以有点迷惑性。B答案***哲学家***是最不符合的。
5.C主旨题。本文从各个方面谈及英语作为一种语言的发展变化，但并不是讲述英语的历史。所以选项A不对，选项C作为文章的题目最为贴切。选项B只是文章阐述的一个方面，不够全面。文章是在谈到英语的不断变化的时候谈到了现代英语的一些特点，所以选项D也失之于片面。
Culture is one of the most challenging elements of the international marketplace. 『This system of learned behavior patterns characteristic of the members of a given society is constantly shaped by a set of dynamic variables: language, religion, values and attitudes, manners and customs, aesthetics, technology, ecation, and social institutions.』① To cope with this system, an international manager needs both factual and interpretive knowledge of culture. To some extent, the factual knowledge can be learned; its interpretation es only through experience.
The most plicated problems in dealing with the cultural environment stem from the fact that one cannot learn culture—one has to live it. Two schools of thought exist in the business world on how to deal with cultural diversity. One is that business is business the world around, following the model of Pepsi and McDonald’s. In some cases, globalization is a fact of life; however, cultural differences are still far from converging.
The other school proposes that panies must tailor business approaches to indivial cultures. Setting up policies and proceres in each country has been pared to an organ transplant; the critical question centers around acceptance or rejection. The major challenge to the international manager is to make sure that rejection is not a result of cultural myopia or even blindness.
Fortune examined the international performance of a dozen large panies that earn 20 percent or more of their revenue overseas. The internationally successful panies all share an important quality: patience. They have not rushed into situations but rather built their operations carefully by following the most basic business principles. These principles are to know your adversary, know your audience, and know your customer.
1. According to the passage, which of the following is true?
A. All international managers can learn culture.
B. Business diversity is not necessary.
C. Views differ on how to treat culture in business world.
D. Most people do not know foreign culture well.
2. According to the author, the model of Pepsi .
A. is in line with the theories of the school advocating the business is business the world around
B. is different from the model of McDonald’s
C. shows the reverse of globalization
D. has converged cultural differences
3. The two schools of thought .
A. both propose that panies should tailor business approaches to indivial cultures
B. both advocate that different policies be set up in different countries C. admit the existence of cultural diversity in business world
D. Both A and B
4. This article is supposed to be most useful for those .
A. who are interested in researching the topic of cultural diversity
B. who have connections to more than one type of culture
C. who want to travel abroad
D. who want to run business on International Scale
5. According to Fortune, successful international panies .
A. earn 20 percent or more of their revenue overseas
B. all have the quality of patience
C. will follow the overseas local cultures
D. adopt the policy of internationalization
Vocabulary
1. dynamic adj. 动态的 2. variable n. 变数
aesthetics n. 美学 4. factual adj. 事实的
5. interpretative adj. 解释的 6. converge v. 聚合
7. transplant v. 移植8. myopia n. 近视 9. adversary n. 对手
长难句解析
①【解析】此句虽然很长，但考生只要认清它的主干，就很容易了解本句的意思。这个句子为一个简单句，主语为：“this system”，谓语为“is shaped”。
【译文】特定社会成员特点构成的行为方式体系不断地被一系列动态变数所左右：如语言、信仰、价值与态度、礼仪与风俗、审美、技术、教育及社会体制。
答案与详解
【短文大意】本文主要讲述文化背景对商业运作的影响，文中列举了商界中存在的对于文化多样性的两种观点。
C推断题。意为“对在商业中怎样对待文化有着不同意见”。 文化在商业中是一个很具挑战性的因素。不同的国家与地区可能会有不同的文化体系。在商业中，应该怎样对待不同的文化，商业界存在着不同的看法。
2. A细节题。意为“……与同意世界商业一体化的派别的主张是一致的”。 Pepsi采纳的是国际化的商业风格，这与那些主张国际化的派别的意见是相一致的。
3. C推断题。意为“承认商业世界中文化的多元性”。两个派别都承认商业世界中文化的多元性。他们的不同在于，应该对待不同的文化，应该搞国际化还是对不同的文化采取不同的策略。
4. D主旨题。由文中的例子可以知道，作者主要关心的并不是研究多种文化形态，而是文化背景对商业运作的影响。所以D是正确答案。
5. B细节题。意为“都具有耐心这一素质”。并非所有成功的国际公司的海外收入都占总收入的20%或以上。它们也不一定全都接纳海外的当地文化，或是采纳国际化策略。

2017年12月大学英语四级阅读理解试题及答案（4）
If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet. By the middle of the 21st century, if present trends continue, we will have used up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however, has recently been suggested by American scientist, Professor Carl Sagan.
Sagan believes that before the earth'毕衡s resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.
Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time proce oxygen, should be bred in condition similar to those on Venus. As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere. In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.
手山做When the algae have done theri work, the atmosphere will become cooler, but befor man can set foot on Venus it will be neccessary for the oxygen to proce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproced on Venus.
1. Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ________.
a. food
b. oil
c. space
d. resources
2. Carl Sagan believes that Venus might be colonized from earth because ________
a. it might be possible to change its atmosphere
b. its atmosphere is the same as the earth's
c. there is a good supply of water on Venus
d. the days on Venus are long enough
3. On Venus there is a lot of ________.
a. water
b. carbon dioxide
c. carbon monoxide
d. oxygen
4. Algae are plants that can ________.
a. live in very hot temperatures
b. live in very cold temperatures
c. manufacture oxygen
d. all of the above
5. Man can land on Venus only when ________.
a. the algae have done their work
b. the atmosphere becomes cooler
c. thereis oxygen
d. it rains there
