Scientists are trying to make the deserts into good land again. They want to bring water to the deserts so that people can live and grow food. Even so, more and more of the earth is becoming desert all the time. Why Scientists think that people make deserts. People are doing bad things to the earth. Some people on the earth do not get very much rain. Yet, they still do not become deserts. This is because there are some small green plants growing there. Plants help keep water in the earth. Plants do not let the wind blow the dirt away. Without plants, the land can become a desert much more easily. A man decides to make a farm in a very dry place. He digs in the earth and takes away the grass and plants that are already growing on the dry land. He makes a farm. He puts plants in rows. The sun is very hot. It makes the land even drier. When the rain comes, it runs between the rows of plants. It washes the good dirt away. When the wind comes, it blows between the rows of plants. It blows the good dirt away. Soon the land is not good enough for a farm any more. The man lets his animals eat all the plants on it. Now the land does not have any plants on it. The sun and wind dry the land and all of the good dirt away, Now the land is a desert.A desert is probably （） A．grassy B．wet C．treeless D．muddy

Just seven years ago,the Jarvik-7 artificial(人造的)heart was being cheered as the model of human creativeness. The sight of Barney Clark―alive and conscious after trading his diseased heart for a metal-and-plastic pump^convinced the press，the public and many doctors that the future had arrived. It hadn't. After monitoring production of the Jarvik-7, and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure ) ，the U.S. Food and Drug Administration concluded that the machine was doing more to endanger lives than to save them. Last week the agency cancelled its earlier approval, effectively banning the device. The recall may hurt Symbion Inc.，maker of the Jarvik-7，but it won' t end the request for an artificial heart. One problem with the banned model is that the tubes connecting it to an external power source created a passage for infection. Inventors are now working on new devices that would be fully placed,along with a tiny power pack,in the patient's chest. The first sample products aren't expected for another 10 or 20 years. But some people are already worrying whether they'll work―and that America's overextended (开支过大的)health-care programs will lose a precious 2.5 billion to 5 billion a year providing them for a relatively few dying patients. If such expenditures(开支)cut into funding for more basic care,the net effect could actually be a decline in the nation,s health. ( ) 8. According to the passage，the Jarvik-7 artificial proved to be . A. a good life-saver B. a technical wonder C. an effective means to treat heart disease D. a technical failure ( ) 9. From the passage we know that Symbion Inc. .

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.
