With environmental damage from coal- and gas-derived power already at crisis levels, renewable energy sources are becoming more and more attractive. Wind power, one _______ 41 _______ and relatively cheap renewable energy source that contributes no toxic _______ 42 _______ to the environment, seems, to many of us, highly ideal.But there are some people who disagree and are against the installation of new wind turbines. They cite (援引) bird deaths as a(n) _______ 43 _______ side-effect of wind-generated power. Through various forms of protests, they hope to express their concern and force change, so that birds could be saved from death caused by the _______ 44 _______ of wind turbine blades.No one really knows how many birds die each year as a result of the _______ 45 _______ wind power industry. Most studies focus on only one or two wind farms. Yet, published studies suggest that wind farms _______ 46 _______ considerably in the risk they pose to birds. Some wind turbines don't appear to kill any birds, while others are believed to kill as many as 40 birds per turbine per year.Though there is no denying that existing reports tell us little about the total number of birds killed each year, they do suggest one thing: Changes are being _______ 47 _______ to save birds from the rotary blades. For example, in some countries, it is required that wind farms should not be built on bird _______ 48 _______ routes, or in areas with high bird populations. It is also often demanded that the surface areas of turbine blades be made much larger, so that they don't have to _______ 49 _______ as fast to generate power – slower-moving blades usually mean fewer bird _______ 50 _______ . Some reports even argue that wind power can actually save many birds if it is well-planned and increasingly used to replace power generation from fossil fuels.

42题

  • 考查知识点:名词的选择,要与“toxic”搭配,且符合风能对环境影响的描述。
  • 解题思路:前文提到“contributes no toxic...”,说明这里需要一个表示污染物的名词。“particulates”意为“颗粒物”,风能不像煤炭和天然气发电那样会排放有毒颗粒物,符合文意。
  • 解析:在能源领域,“particulates”是常见的污染物类型,风能的优势之一就是不产生这类有毒物质,所以选择“particulates”。

43题

  • 考查知识点:形容词的选择,用于修饰“side - effect”。
  • 解题思路:根据“bird deaths”可知,这是一个令人悲伤的、悲剧性的副作用。“tragic”意为“悲剧的,悲惨的”,能很好地表达这种负面效果。
  • 解析:鸟类死亡是一个严重的问题,用“tragic”来形容这种副作用,突出了其严重性和令人惋惜的程度,所以选择“tragic”。

  • Americans experience more food recalls (召回) today than they did five years ago, especially when it comes to meat and poultry (家禽). Meat and poultry recalls increased by two-thirds from 2013 to 2018, while food recalls overall went up 10%, according to the report recently published by the U.S. Public Interest Research Group.Meanwhile, the U.S. Centers for Disease Control and Prevention estimates (估计) 48 million people get sick, 128,000 are hospitalized and 3,000 die from food-borne disease each year in the U.S. "We are looking for the farm-to-fork preventative solutions," said Adam Garber, the research group's consumer watchdog. "By doing that, we can protect people's health."Over the five-year period, poultry posted the most recalls (168), followed by beef (137) and pork (128). The report shows the most serious meat recalls are on the rise. Among meat and poultry, the number of Class I recalls has increased by 83%, nearly doubling. Class I, the most serious of the recalls, is issued when there is a reasonable probability that the food will cause health problems or death.53. When would Class I recalls be issued?A. When the food is likely to cause health problems or death.B. When there are too many complaints from customers.C. When the food problem lasts for five years.D. When the product quality is below standard.

  • 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.

  • 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.
