【题文】In nature, you may see many insects (昆虫）and animals of different colors. Have you ever wondered why?Locusts(蝗虫) are super delicious food for birds, but it is not always an easy job for birds to catch them .It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops(庄稼). When crops are young, locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do. Brown bears, tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive, they have to hide themselves in the daytime and appear only at night.Have you ever noticed some even stranger acts(行为)? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over, its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.【小题1】 It is not easy for birds to catch locusts because_________.A．locusts are good runnersB．locusts can jump very highC．locusts are smarter than birdsD．locusts can change their color【小题2】According to the passage, most soil insects_________A．do not have bright colorsB．change their colors with the soilC．do not live in a dark and wet environment D．eat colorful insects like butterflies and bees【小题3】What’s the meaning of the underlined word “survive” in the passage?A．繁殖B．产卵C．觅食D．生存【小题4】The ink fish _______so that its enemies will not see it.A．changes its colorB．makes the water around it blackC．appears only at nightD．hides itself in the sea rocks【小题5】What is the main idea of this passage?A．Some insects and animals have different skills.B．Some insects and animals are clever than we think.C．Some insects and animals use colors to protect themselves.D．Some insects and animals can get used to the environment easily.

You nod and people know you ale saying “Yes”. Other things can also carry messages. For example, a sign on the bus helps you to know which bus to take. A sign on the door tells you where to go in or out. Have you ever noticed that there are a lot of signs around you and you receive messages from them all the time?

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.
