The Argument over Salt and HealthResearch shows that eating even a little less salt can greatly help the heart. The study was published in the New England Journal of Medicine. The scientists used a computer model to predict how just three grams less salt a day would affect heart disease in the United States.The scientists said the results would be thirteen percent fewer heart attacks, eight percent fewer strokes, four percent fewer deaths and eleven percent fewer new cases of heart disease, and two hundred forty billion dollars in health care savings annually. Researchers said it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year.The researchers were from the University of California, San Francisco, Stanford University and Columbia University.They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt. Such campaigns are already in place in Britain, Japan and Finland.However, some scientists say such a campaign is an experiment with the health of millions of people.

题目解答

答案

我们来一步一步分析这道题目。 题目是: > According to some research, eating a little less salt can do good to the heart. > A. True > B. False > C. Not Given 我们需要判断这句话“根据一些研究,少吃一点盐对心脏有好处”在原文中是否成立。 --- **第一步:理解题干关键词** - “According to some research” —— 根据一些研究 - “eating a little less salt” —— 少吃一点盐 - “can do good to the heart” —— 对心脏有好处 我们要在原文中找是否有提到“一些研究”表明“少吃盐对心脏有益”。 --- **第二步:回到原文寻找相关信息** 原文第一句话就是: > Research shows that eating even a little less salt can greatly help the heart. 翻译:研究表明,即使少吃一点盐,也能大大有助于心脏健康。 这句话非常明确地表达了题干中的观点。 - “Research shows” 对应 “According to some research” - “eating even a little less salt” 对应 “eating a little less salt” - “can greatly help the heart” 对应 “can do good to the heart” 所以,原文一开始就明确支持这个说法。 此外,后文还提到: - 这项研究发表在《新英格兰医学杂志》上; - 科学家通过模型预测,每天少吃3克盐,可以显著减少心脏病发作、中风、死亡等; - 每年可节省数千亿美元医疗费用; - 可预防十万人的心脏病发作和九万两千人死亡。 这些都进一步支持“少吃盐对心脏有益”的结论。 虽然文中也提到了一些反对意见,比如Michael Alderman等科学家认为这种全国性减盐运动是一种“对数百万人健康的实验”,但这并不否定“一些研究”支持减盐对心脏有益的事实。题干只是说“根据一些研究”,并没有说“所有研究”或“没有争议”。 因此,只要存在研究支持这一观点,答案就是“True”。 --- **第三步:排除其他选项** - B. False(错误):不对,因为原文明确说研究显示有益。 - C. Not Given(未提及):也不对,因为原文明确提到了相关研究和结论。 --- **结论:** 题干的说法在原文中有明确支持。 **答案:A. True** \boxed{A}

解析

本题考查细节理解能力,需要判断题干中的陈述是否与原文信息一致。关键在于抓住题干中的核心短语“some research”和“eating a little less salt”,并结合原文首句的直接表述进行判断。原文明确指出“Research shows that eating even a little less salt can greatly help the heart”,与题干高度吻合,因此答案为True。

关键点定位

  1. 题干核心:根据某些研究,少吃一点盐对心脏有益。
  2. 原文对应:首句直接说明“研究表明,即使少吃一点盐,也能大大帮助心脏”。

逻辑分析

  • 直接匹配:原文首句中的“Research shows”对应题干中的“According to some research”,“eating even a little less salt”对应“eating a little less salt”,“can greatly help the heart”对应“can do good to the heart”。
  • 数据支持:后续内容(如减少心脏病、中风数据)进一步验证了“少吃盐有益心脏”的结论。
  • 反对意见不影响:文中提到的反对声音(如Michael Alderman的批评)仅针对“全国性减盐运动”,并未否定“某些研究支持减盐对心脏有益”的事实。

排除干扰项

  • B. False:错误,因为原文明确支持题干观点。
  • C. Not Given:错误,因为原文首句已明确提及相关研究。

  • Americans experience more food recalls (召回) today than they did five years ago, especially when it comes to meat and poultry (家禽). Meat and poultry recalls increased by two-thirds from 2013 to 2018, while food recalls overall went up 10%, according to the report recently published by the U.S. Public Interest Research Group.Meanwhile, the U.S. Centers for Disease Control and Prevention estimates (估计) 48 million people get sick, 128,000 are hospitalized and 3,000 die from food-borne disease each year in the U.S. "We are looking for the farm-to-fork preventative solutions," said Adam Garber, the research group's consumer watchdog. "By doing that, we can protect people's health."Over the five-year period, poultry posted the most recalls (168), followed by beef (137) and pork (128). The report shows the most serious meat recalls are on the rise. Among meat and poultry, the number of Class I recalls has increased by 83%, nearly doubling. Class I, the most serious of the recalls, is issued when there is a reasonable probability that the food will cause health problems or death.53. When would Class I recalls be issued?A. When the food is likely to cause health problems or death.B. When there are too many complaints from customers.C. When the food problem lasts for five years.D. When the product quality is below standard.

  • The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.

  • The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.
