题目解答

答案

首先,我们来阅读并理解这篇短文的内容。

文章大意:

  • 第一段: 许多人想保持健康,但不知道如何开始。事实上,有三种简单的方法可以保持健康。
  • 第二句(First...): 首先,吃均衡的饮食。你应该多吃水果、蔬菜和谷物,少吃糖和脂肪。
  • 第三句(Second...): 其次,定期锻炼。即使每天散步 30 分钟也能帮助你保持健康。
  • 第四句(Third...): 第三,获得足够的睡眠。大多数成年人每晚需要大约 7 到 8 小时的睡眠。
  • 结尾: 记住,开始健康的生活方式永远不晚。小的改变可以带来大的不同。

题目分析:
题目问的是:“What is the main purpose of the passage?”(这篇文章的主要目的是什么?)

我们需要根据文章的整体内容来判断作者写作的意图。文章开头引出“保持健康的方法”,接着用“First, Second, Third”分别列出了三个具体的建议(饮食、锻炼、睡眠),最后总结鼓励大家开始健康的生活方式。因此,整篇文章的核心是在提供如何保持健康的建议。

选项分析:

  • A. To explain why people get sick.(解释人们为什么会生病。)
    文章中并没有探讨人们生病的原因,而是侧重于如何保持健康,所以 A 选项不符合。
  • B. To give advice on how to keep healthy.(就如何保持健康给出建议。)
    文章通过列举饮食、锻炼、睡眠三个方面,明确给出了保持健康的建议,这与文章的主旨完全吻合。
  • C. To compare different diets.(比较不同的饮食。)
    文章只提到了“balanced diet”(均衡饮食)的建议,并没有比较不同的饮食方式,所以 C 选项不符合。
  • D. To describe a healthy meal.(描述一顿健康的餐食。)
    文章虽然提到了饮食,但只是泛泛地建议多吃蔬果谷物、少吃糖和脂肪,并没有具体描述一顿健康的餐食。而且这只是文章提到的三点之一,不能概括全文目的,所以 D 选项不符合。

结论:
综上所述,这篇文章的主要目的是给出如何保持健康的建议。

正确答案:B

解析

本题考查对文章主旨大意的理解。解题思路是先通读文章,把握文章整体内容,明确文章围绕的核心话题,再分析每个选项与文章核心内容的匹配度。

  • 文章开篇指出很多人想保持健康却不知如何开始,接着用“First, Second, Third”分别阐述了三种保持健康的简单方法,即吃均衡饮食、定期锻炼和保证充足睡眠,最后鼓励人们开始健康的生活方式。
  • 选项A:文章中并未提及人们生病的原因,主要围绕的是保持健康的方法,所以A选项不符合文章主旨。
  • 选项B:文章详细给出了饮食、锻炼和睡眠三方面保持健康的建议,与选项B内容相符。
  • 选项C:文章仅提到了均衡饮食的建议,没有对不同饮食进行比较,所以C选项不正确。
  • 选项D:文章虽涉及饮食建议,但只是宽泛地提及多吃蔬果谷物、少吃糖和脂肪,没有具体描述一顿健康的餐食,且这只是文章内容的一部分,不能概括全文目的,所以D选项不合适。

  • 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.

  • question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

  • 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.
