J preventing34. N sufficient35. F increased【原文】As if you needed another reason to hate the gym, it now turns out that exercise can exhaust not only your muscles, but also your eyes. Fear not, however, for coffee can perk them right up again. During vigorous exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a phenomenon called “central fatigue,” in which an imbalance in the body’s chemical messengers prevents the central nervous system from directing muscle movements effectively. It was not known, however, whether central fatigue might also affect motor systems not directly involved in the exercise itself—such as those that move the eyes. To find out, researchers gave 11 volunteers a carbohydratesolution either with a moderate dose of caffeine—which is known to stimulate the central nervous system—or as a placebo without, during 3 hours of cycling. After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still control their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, preventing their ability to capture new visual information. The caffeine—the equivalent of two strong cups of coffee—was sufficient to counteract this effect, with some cyclists even displaying increased eye movement speeds, the team reports today in Scientific Reports.

6月英语四级考试阅读题及详解2017年6月英语四级考试阅读题及详解A friend in need is a friend in indeed. 以下是店铺为大家搜索整理的2017年6月英语四级考试阅读题及详解,希望能给大家带来帮助!Questions 21 to 25 are based on the following passage:It is simple enough to say that since books have classes fiction, biography, poetry—we should separate them and take from each what it is right that each should give us. Yet few people ask from books what books can give us. Most commonly we come to books with blurred and divided minds, asking of fiction that it shall be true, of poetry that it shall be false, of biography that it shall be flattering, of history that it shall enforce our own prejudices. If we could banish all such preconception when we read, that would be an admirable beginning. Do not dictate to your author; try to become him. Be his fellow worker and accomplice(同谋). If you hang back, and reserve and criticize at first, you are preventing yourself from getting the fullest possible value from what you read. But if you open your mind as widely as possible, then signs and hints of almost imperceptible finess(委婉之处), from the twist and turn of the first sentences, will bring you into the presence of a human being unlike any other. Steep yourself in this, acquaint yourself with this, and soon you will find that your author is giving you, or attempting to give you, something far more definite. The thirty two chapters of anovel—if we consider how to read a novel first—are an attempt to make something as formed and controlled as a building but words are more impalpable than bricks, reading is a longer and more complicated process than seeing. Perhaps the quickest way to understand the elements of what a novelist is doing is not to read,but to write; to make your own experiment with the dangers and difficulties of words. Recall, then, some event that has left a distinct impression on you—how at the corner of the street, perhaps, you passed two people talking. A tree shook; an electric light danced; the tone of the talk was comic, but also tragic; a whole vision, an entire conception, seemed contained in that moment.21.What does the author mean by saying “Yet few people ask from books what books can give us.”?A.The author means that lots of people read few books.B.The author thinks that readers have only absorbed part of knowledge in books.C.The author holds that few people have a proper idea about what content some kind of books should include.D.The author considers that readers can scarcely understand most of the books.22.According to the passage, which of the following statement is right?A.A reader should find some mistakes when he is reading.B.The more difficult a book is, the more you can get from it.C.To read something is easier than to watch something.D.One should be in the same track with the writer when he is reading.23.What is the possible meaning of “impalpable” (Paragraph 2) in the passage?A.Clear.B.Elusive.C.Delicate.D.Precise.24.What’s the main idea of this passage?A.The importance of reading.B.The proper way to read.C.How to get most from one book.D.The characters of a good book.25.When a writer is writing he often get the whole conception ____.A.after a long time’s thinkingB.through an instant inspirationC.according to his own experienceD.by way of watching the objects attentively参考答案:21.答案B。

20176月英语四级考试答案完整版(2)2017四级六月考试答案真题:阅读题C(卷二)Passage One"Sugar, alcohol and tobacco," economist Adam Smith once wrote, "are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation."Two and a half centuries on, most countries impose some sort of tax on alcohol and tobacco. With surging obesity levels putting increasing strain on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found a fall in purchases of taxed drinks as well as a rise in sales if untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after its introduction, amid claims that consumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattier fare.The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount of sugar in their beverages.Many of the reductions over the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in aproduct, or by finding an alternative ingredient. More recently, however.Some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.While reformulating recipes(配方)is one way to improve public health, it should be part of a multi-sided approach. The key is to remember thatthere is not just one solution. To deal with obesity, a mixture of approaches-including reformulation, taxation and adjusting portion sizes-will be needed. There is no silver bullet.46.What did Adam Smith say about sugar, alcohol and tobacco.A.They were profitable to manufacture.B.They were in ever-increasing demand.C.They were subject to taxation almost everywhere.D.They were no longer considered necessities of life.【答案】C47.Why have many countries started to consider taxing sugar?A.They are under growing pressures to balance their national budgets.B.They find it ever harder to cope with sugar-induced health problems.C.They practice of taxing alcohol and tobacco has proved both popular and profitable.D.The sugar industry is overtaking alcohol and tobacco business in generating profits.【答案】B48.What do we learn about Danish taxation on fat-rich foods?A.It did not work out as well as was expected.B.It gave rise to a lot of problems on the border.C.It could not succeed without German cooperation.D.It met with firm opposition from the food industry.【答案】A49.What is the more recent effort by food companies to make foods and drinks both healthy and tasty?A.Replacing sugar or salt with alternative ingredients.B.Setting a limit on the amount of sugar or salt in their products.C.Investing in research to find ways to adapt to consumers' needs.D.Adjusting the physical composition of their products.【答案】D50.What does the author mean by saying, at the end of the passage, "There is no silver bullet"(Line 4, Para 7)?A.There is no single easy quick solution to the problem.B.There is no hope of success without public cooperation.C.There is on hurry in finding ways to solve the obesity problem.D.There is no effective way to reduce people's sugar consumption.【答案】APassage TwoYou may have heard some of the fashion industry horror stories: models eating tissues or cotton balls to hold off hunger, and models collapsing from hunger-induced heart attacks just seconds after they step off the runway.Excessively skinny models have been a point of controversyfor decades, and two researchers say a model's body mass should be a workspace health and safety issue. In an editorial released Monday in the American Journal of Public Health, Katherine Record and Bryn Austin made their case for government regulation of the fashion industry.The average international runway model has a body mass index (BMI) under 16-low enough to indicate starvation by the World Health Organization's standard. And Record and Austin are worried not just about the models themselves, but about the vast number of girls and women their images influence."Especially girls and tens", says Record. "Seventy percent of girls aged 10 to 18 report that they define perfect body image based on what they see in magazines." That's especially worrying, she says, given that anorexia(厌食症)results in more deaths than does any other mental illness, according to the National Institute of Mental Health.It's commonly known that certain diseases are linked with occupations like lung disease in coal miners. Professional fashion models are particularly vulnerable to eating disorders resulting from occupational demands to maintain extreme thinness.Record's suggestion is to prohibit agents from hiring models with a BMI below 18.In April, France passed a law setting lower limits for a model's weight. Agents and fashion houses who hire models with BMI under 18 could pay $82,000 in fines and spend up to 6 months in jail. Regulating the fashion industry in the United States won't be easy, Record says. But with the new rules in France, U.S. support could make a difference. "A designer can't survive without participating in Paris Fashion Week", she says, adding, "Our argument is that the same would be true of New YorkFashion Week."51.What do Record and Austin say about fashion models' body mass?A.It has caused needless controversy.B.It is focus of the modeling business.C.It is but a matter of personal taste.D.It affects models' health and safety.【答案】D52.What are Record and Austin advocating in the Monday editorial?A.A change in the public's view of female beauty.ernment legislation about models' weight.C.Elimination of forced weight loss by models.D.Prohibition of models eating non-food stuff.【答案】B53.Why are Record and Austin worried about the low body mass index of models?A.It contributes to many mental illnesses.B.It defines the future of the fashion industry.C.It has great influence on numerous girls and women.D.It keeps many otherwise qualified women off the runaway.【答案】C54. What do we learn about France's fashion industry?A.It has difficulty hiring models.B.It has now a new law to follow.C.It allows girls under 18 on the runway.D.It has overtaken that of the United States.【答案】B55. What does Record expect of New York Fashion Week?A.It will create a completely new set of rules.B.It will do better than Paris Fashion Week.C.It will differ from Paris Fashion Week.D.It will have models with a higher BMI.【答案】D翻译真题二:白色翻译原文:随着中国的改革开放,如今很多年轻人都喜欢举行西式婚礼。

2017六月四级真题及答案大学英语四级阅读真题原文Passage OneQuestions 56 to 60 are based on the following passage.Across the rich world, well-educated people increasingly work longer than the less-skilled. Some 65% of American men aged 62-74 with a professional degree are in the workforce, compared with 32% of men with only a high-school certificate. This gap is part of a deepening divide between the well-educated well-off and the unskilled poor. Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled. The consequences, for individuals and society, are profound.The world is facing an astonishing rise in the number of old people. And they will live longer than ever before. Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity (长寿) translated into more years in retirement rather than more years at work, has persuaded many observers that this shift will lead to slower economic growth, while the swelling ranks of pensioners will create government budget problems.But the notion of a sharp division between the working young and the idle old misses a new trend, the growing gap between the skilled and the unskilled. Employment rates arefalling among younger unskilled people, whereas older skilled folk are working longer. The divide is most extreme in America, where well-educated baby-boomers (二战后生育高峰期出生的美国人) are putting off retirement while many less-skilled younger people have dropped out of the workforce.Policy is partly responsible. Many European governments have abandoned policies that used to encourage people to retire early. Rising life expectancy(预期寿命), combined with the replacement of generous defined-benefit pension plans with less generous defined-contribution ones, means that even the better-off must work longer to have a comfortable retirement. But the changing nature of work also plays a big role. Pay has risen sharply for the highly educated, and those people continue to reap rich rewards into old age because these days the educated elderly are more productive than the preceding generation. Technological change may well reinforce that shift: the skills that complement computers, from management knowhow to creativity, do not necessarily decline with age.大学英语四级阅读题目注意:此部分试题请在答题卡2上作答。
