【阅读理解：七选五】选择正确的句子选项ABCD（必须大写）填入文中，下拉页面可看见选项。Much of the work in today's world is accomplished（完成）in teams. Most people believe the best way to build a great team is to gather a group of the most talented individuals. 1 Companies spend millions hiring top business people. Is their money well spent? 2 They focused on football, basketball and baseball. The results are mixed. For football and basketball, adding talented players to a team proves a good method, but only up to the point where 70% of the players are top talent; above that level, the team's performance begins to decline. Interestingly, this trend isn't evident in baseball, where additional individual talent keeps improving the team's performance.To explain this phenomenon, the researchers explored the degree to which a good performance by a team required its members to coordinate（协调）their actions. 3 In baseball, the performance of individual players is less dependent on teammates. They conclude that when task interdependence is high, team performance will suffer when there is too much talent, while individual talent will have positive effects on team performance when task interdependence is lower. If a basketball star is, for example, trying to gain a high personal point total, he may take a shot himself when it would be better to pass the ball to a teammate, affecting the team's performance. Young children learning to play team sports are often told, "There is no I in TEAM." 4 Another possibility is that when there is a lot of talent on a team, some players may make less effort. Just as in a game of tug-of-war（拔河比赛）, whenever a person is added, everyone else pulls the rope with less force. 5 An A-team may require a balance—not just A players, but a few generous B players as well.A.It's not a simple matter to determine the nature of talent.B.Sports team owners spend millions of dollars attracting top talent.C.The group interaction and its effect drew the researchers' attention.D.Stars apparently do not follow this basic principle of sportsmanship.E.Several recent studies examined the role of talent in the sports world.F.Building up a dream team is more complex than simply hiring the best talent.G.This task interdependence distinguishes baseball from football and basketball.
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. . A. has been banned by the government from producing artificial hearts B. will review the effects of artificial hearts before designing new models C. may continue to work on new models D. can make new models of artificial hearts available on the market in 10 to 20 years ( ) 10. The new models of artificial hearts are expected . A. to have a working life of 10 or 20 years B. to be set fully in the patient' s chest C. to be equipped with an external power source D. to create a new passage for infection ( ) 11. The underlined word "them" refers to ―. A. doctors who treat heart diseases B. makers of artificial hearts C. America's health-care programs D. new models of artificial hearts ( ) 12. Some people feel that . A. artificial hearts are seldom effective B. the country is not spending enough money on artificial hearts C. the country should not spend so much money on artificial hearts D. America's health-care programs are not doing enough for the nation's health

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.

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.
