Miss Gorgers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, "Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street. Which of you would hear what I said earlier, my brother or you and for what reason?"Tom at once answered, "Your brother. Because electricity travels faster than sound waves." "That's very good," Miss Gorgers answered, but then one of the girls raised her hand, and Miss Gorgers said, "Yes, Kate?" "I disagree." Kate said, "Your brother would hear you earlier because when it's 11 o'clock here it's only 8 o'clock in Los Angeles." (1)Miss Gorgers was teaching her class .

Stress may be defined as the response of the body to any demand. Whenever people experience something pleasant or unpleasant, we say they are under stress. We call pleasant kind “eustress”, the unpleasant kind “distress”. People sometimes compare our lives with that of the cave man, who didn’t have to worry about the stock market or the atomic bomb. They forget that the cave man worried about being eaten by a bear or about dying of hunger—things that few people worry about today. It’s not that people suffer more stress today; it’s just that they think they do. It is inconceivable that anyone should have no stress at all. Most people who are ambitious and want to accomplish something live on stress. They need it. But excessive stress is by all means harmful. Worse, chronic exposure to stress over a long time may cause more serious diseases and may actually shorten your life. The most frequent causes of distress in man are psychological – lack of adaptability, not having a code of behavior. So the secret of cooping with stress is not to avoid it but to do what you like to do and what you were made to do, at your own rate. For most people, it is really a matter of learning how to behave in various situations. The most important thing is to have a code of life, to know how to live. The modern man is suffering _____. A.more stress than the cave man B.less stress than the cave man C.different stress from the cave man D.same stress as the cave man According to the passage, which of the following statements is NOT true?A.Every one will suffer certain kinds of stress in his life B.Chronic exposure to stress may shorten your life C.Excessive stress is especially harmful to health D.Most people can learn to avoid stress. In the second sentence of the third paragraph, “live on stress” implies that ___.A.stress is necessary to them. B.they can control stress. C.stress is by all means harmful to them. D.they have too much stress. According to the passage, one should _______.A.try to avoid as much stress as possible B.cope with stress in different ways C.learn to do things at his own rate D.have the response of the body to any demand Which of the following is not an example that causes distress?A.Lacking in adaptability and code of life B.Killing a bear in hunting C.The failure to pass final examinations. D.Having an economic problem.

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. [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.
