【篇一】2020年9月大學(xué)英語四級閱讀文章
As the 11 of life continues to increase, we are fast losing the art of relaxation. Once you are in habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often 12 to be. A certain amount of stress is 13 to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor 14 and ill health.
The amount of stress a person can 15 depends very much on the individual. Some people are not afraid of stress, and such characters are 16 prime material for managerial responsibilities. Others lose heart at the first signs of 17 difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so 18 , but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued 19 to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot 20 stress from our lives(it would be unwise to do so even if we could) , we need to find ways to deal with it.
A. cancel B. pace C. extreme D. automatically
E. remove F. vital G. performance H. supposed
I. rate J. exposure K. achievement L. unusual
M obviously N withstand O harsh
答案：11. B 12. H 13. F 14. G 15. N 16. M 17. L 18. C 19. J 20. E

Taste is such a subjective matter that we don't usually conduct preference tests for food. The most you can say about anyone's preference, is that it's one person's opinion. But because the two big cola(可樂) companies Coca-Cola and Pepsi Cola are marketed aggressively, we've wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either C0ca-Cola or Pepsi fans: Find your brand in a blind tasting.
We invited staff volunteers who had a strong liking for either Coca-Cola Classic (傳統(tǒng)型)or Pepsi, Diet (低糖的)Coke, or Diet Pepsi-These were people who thought they'd have no trouble telling their brand from the other brand. We eventually located 19 regular cola drinkers and 27 diet cola drinkers.
We eventually located 19regular cola drinkers and 27diet cola drinkers. Then we fed them four unidentifiedsamples of cola one at a time, regular colas for the one group, diet versions for the other. We asked themto tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participants 'choices with what mere gum-work would have accomplished.
Getting all four samples right was a tough test, but not too tough, we thought, for people who believed they could recognize their brand. In the end, only 7out of19regular cola drinkers correctly identified theirbrand of choice in all four trials. The diet-cola drinkers did a little worse -only 7of27identified all four samples correctly.
While both groups did better than chance would predict, nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall, half the participants did about as well on the last round of tasting as on the first, so fatigue, or taste burn out, was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.

2.[B] 第4段第2、3句表明可口可樂和百事可樂在味道方面并無多大差異，B與之相符。A、D不是實驗數(shù)據(jù)所表明的事情，故排除;C與原文的意思不相符，也排除。

【篇三】2020年9月大學(xué)英語四級閱讀文章
The way people hold to the belief that a fun-filled, pain-free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain.
As a result, many people avoid the very attempts that are the source of true happiness. They fear the paininevitably brought by such things as marriage, raising children, professional achievement, religious commitment(承擔(dān)的義務(wù)), self improvement.
Ask a bachelor(單身漢) why he resists marriage even though he finds dating to be less and less satisfying.If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quitepainful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features.
Couples with infant children are lucky to get a whole night's sleep or three-day vacation. I don't know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.
Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase ourhappiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increaseour happiness now seems pointless. And it liberates us from envy: we now understand that all those who arealways having so much fun actually may not be happy at all.
練習(xí)題：
Choose correct answers to the question:
1. According to the author, a bachelor resists marriage chiefly because______
A. he is reluctant to take on family responsibilities
B. he believes that life will be more cheerful if he remains single
C. he finds more fun in dating than in marriage
D. he fears it will put an end to all his fun adventure and excitement
2. Raising children, in the author's opinion, is_______
A. a moral duty
B. a rewarding task
C. a thankless job
D. a source of inevitable pain
3. From the last paragraph, we learn that envy sometimes stems from______
A. hatred
B. misunderstanding
C. prejudice
D. ignorance
4. To understand what true happiness is one must_______
A. have as much fun as possible during one's lifetime
B. make every effort to liberate oneself from pain
C. put up with pain under all circumstances
D. be able to distinguish happiness from fun
5. What is the author trying to tell us?
A. Happiness often goes hand in hand with pain.
B. One must know how to attain happiness.
C. It is important to make commitments.
D. It is pain that leads to happiness.
1.[A] 第3段第2句解釋了單身漢為什么不愿結(jié)婚的原因，A項的reluctant to take on family responsibilities是對原文中afraid of making a commitment的同義替換,故選A。本題中D項的干擾性比較強(qiáng)，但這不是單身漢不愿結(jié)婚的直接原因，且文中也說到Marriage has such moments,所以put an end的說法也不正確，故排除。
2.[C] 原文第4段中說，雖然養(yǎng)孩子的過程實在不能算是“有趣”,但決定不要孩子的夫婦們永遠(yuǎn)也不能了解看著孩子長大的那種歡樂以及與孫兒一起玩耍的歡樂。換言之，在作者看來，養(yǎng)孩子雖辛苦，但也是值得的，故答案為C。
3.[B] 文章最后一段最后一句說它還讓我們從嫉妒中解脫出來：我們現(xiàn)在了解到那些總有很多樂趣的人也許根本就不幸福。這說明我們嫉妒別人是誤以為那些總有很多樂趣的人很幸福，這是一種誤解，故選B。
4.[D] 由文章第1段和最后一段第1句可看出要理解真正的幸福就要把fun和happiness區(qū)分開，故選D。
5.[A] 本題是主旨題。主旨題的答案常位于首段或結(jié)尾段。本題的答案可以在文章第1段最后一句找到：通往幸福的路上多半會涉及到痛苦，因此本題選A。D中雖也提到pain,但對分強(qiáng)調(diào)pain對幸福的作用，故錯誤。
【篇四】2020年9月大學(xué)英語四級閱讀文章
Most episodes of absent-mindedness forgetting where you left something or wondering why you just entered aroom-are caused by a simple lack of attention,says Schacter. “You’re supposed to remember something, butyou haven’t encoded it deeply.”
Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phonein a pocket, for example, and don’t pay attention to what you did because you’re involved in a conversation, you’ll probably forget that the phone is in the jacket now hanging in you wardrobe (衣柜). “Your memory itself isn’t failing you,” says Schacter. “Rather, you didn’t give your memory system the information it needed.”
Lack of interest can also lead to absent-mindedness. “A man who can recite sports statistics from 30 years ago,” says Zelinski, “may not remember to drop a letter in the mailbox.” Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on justthat.
Visual cues can help prevent absent-mindedness, says Schacter. “But be sure the cue is clear and available,” he cautions. If you want to remember to take a medication (藥物) with lunch, put the pill bottle on the kitchen table—don’t leave it in the medicine chest and write yourself a note that you keep in a pocket.
Another common episode of absent-mindedness: walking into a room and wondering why you’re there. Most likely, you were thinking about something else. “Everyone does this from time to time,” says Zelinski. The best thing to do is to return to where you were before entering the room, and you’ll likely remember.
練習(xí)題：
Choose correct answers to the question:
1. Why does the author think that encoding properly is very important?
A. It helps us understand our memory system better.
B. It enables us to recall something form our memory.
C. It expands our memory capacity considerably.
D. It slows down the process of losing our memory.
2. One possible reason why women have better memories than men is that ________.
A. they have a wider range of interests
B. they are more reliant on the environment
C. they have an unusual power of focusing their attention
D. they are more interested in what’s happening around them
3. A note in the pocket can hardly serve as a reminder because ________.
A. it will easily get lost
B. it’s not clear enough for you to read
C. it’s out of your sight
D. it might get mixed up with other things
4. What do we learn from the last paragraph?
A. If we focus our attention on one thing, we might forget another.
B. Memory depends to a certain extent on the environment.
C. Repetition helps improve our memory.
D. If we keep forgetting things, we’d better return to where we were.
5. What is the passage mainly about?
A. The process of gradual memory loss.
B. The causes of absent-mindedness.
C. The impact of the environment on memory.
D. A way if encoding and recalling.
1.[B] 事實細(xì)節(jié)題。根據(jù)第2段第1句可知，encoding是關(guān)注某事的一種特殊方式，這影響到以后是否能回憶起這件事來，因此B正確。
2.[D] 事實細(xì)節(jié)題。根據(jù)第3段第3句，“女性比男性的記憶力稍強(qiáng)，這也許是因為她們對周圍的環(huán)境更加注意，而記憶正是依靠這個”，故選D “她們對于周圍發(fā)生的事更感興趣”。
3.[C] 事實細(xì)節(jié)題。根據(jù)第4段首句中說到的“視覺線索可以防止遺忘某事”可知破折號之后的警告“不要把藥瓶放在藥箱里，然后寫一張紙條裝進(jìn)口袋”正是為了防止藥瓶、提示性信條離開了視線，故選C。
4.[A] 推斷題。根據(jù)最后一段的前兩句“心不在焉的另一個常見的情景是:走進(jìn)房間,卻不知為什么要進(jìn)來。你很有可能是在想別的事”,可知本題答案為A。
5.[B] 主旨題。根據(jù)第1、3、5段的首句可以得出，本文主要講的是精神不集中的原因，故選B。
