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.

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.

D　　Some radio signals were heard in 1967. They were coming from a point in the sky where there was unknown star. They were coming very regularly, too — about once a second, as if they were controlled by clock.　　The scientists who heard the signals did not tell anybody else. They were rather afraid to tell in case they frightened people. The signals were coming from a very small body—no bigger, perhaps than the earth. Was that why no light could be seen from it? Or were the signals coming from a planet that belonged to some other star? There was no end to the questions, but the scientists kept the news secret. "Perhaps there are intelligent beings out there." they thought, "who are trying to send messages to other planets, or to us?" So the news was not given to the newspaper. Instead, the scientists studied the signals and searched for others like them. Well, all that happened in 1967 and 1968. Since then scientists have learnt more about those strange, regular, radio signals. And they have told the story, of course.　　The signals do not come from a planet; they come from a new kind of star called a "pulsar"(脉冲星). Pulsars are strong radio stars. They are the smallest but the heaviest stars we know at present. And we can be sure of this: no intelligent beings are living on them. Until now over a hundred other pulsars have been found, and most of them are very like the first one.　　Recently, Chinese researchers have discovered six pulsars, which are super heavy remains of massive stars, using its Five-hundred-meter Aperture Spherical Radio Telescope, known as FAST, thus opening a "new era of Chinese original space discovery". Li Di, the telescope's deputy chief engineer, said FAST is set to be fully operational by the end of 2019. Meanwhile, scientists there will continue to test FAST and cooperate with foreign scientists on space exploration.The radio signals discussed in this passage _____.A. were regularB. were controlled by a clockC. were heard in 1967 onlyD. were secret messagesThe scientists did not tell people about the signals because _____.A. the signals stood for secret messagesB. people might be frightenedC. the signals stood for unimportant messagesD. people would ask them too many questionsA pulsar _____.A. is a well-known satelliteB. is a small and light starC. has intelligent beings that were known at that timeD. is a small heavy star sending out strong radio signalsWhich of the following is TRUE?A. The radio signals were sent by a sky body which was known at that time.B. Scientists have searched for pulsars for many years but found none.C. Chinese researchers have discovered six pulsars using FAST.D. Now is the new era of Chinese space discovery with perfect FAST.

Most children with healthy appetites are ready to eat almost anything that is offered them and a child rarely dislikes food (51) it is badly cooked. The way a meal is cooked and served is most important and an (52) served meal will often improve a child’s appetite. Never ask a child whether he likes or dislikes a food and never (53) likes and dislikes in front of him or allow anybody else to do so. If the father says he hates fat meat or the mother refuses vegetables in the child’s hearing he is (54) to copy this procedure. Take it (55) granted that he likes everything and he probably will. Nothing healthful should be omitted from the meal because of a (56) dislike. At meal times it is a good idea to give a child a small portion and let him (57) back for a second helping rather than give him as much as he is likely to eat all at once. Do not talk too much to the child (58) meal times, but let him get on with his food, and do not allow him to leave the table immediately after a meal or he will soon learn to swallow his food (59) he can hurry back to his toys. Under (60) circumstances must a child be coaxed or forced to eat.55（）。A. withB. asC. overD. for
High in the Swiss Alps many years ago, there lived a lonely shepherd boy who longed for a friend to share his evenings. One night he saw three old men, each holding a glass.
