1、关键词语题型第4题反论题型第5题Recent years have brought minority-owned businesses in the United States unprecedented opportunities as well as new and significant risks. Civil rights activists have long argued that one of the principal reasons why Blacks, Hispanics, and other minority groups have difficulty establ

2、ishing themselves in business is that they lack access to the sizable orders and subcontracts that are generated by large companies. Now Congress, in apparent agreement, has required by law that businesses awarded federal contracts of more than $500,000 do their best to find minority subcontractors

3、and record their efforts to do so on forms filed with the government. Indeed, some federal and local agencies have gone so far as to set specific percentage goals for apportioning parts of public works contracts to minority enterprises.Corporate response appears to have been substantial. According t

4、o figures collected in 1977, the total of corporate contracts with minority businesses rose from $77 million in 1972 to $1.1 billion in 1977. The projected total of corporate contracts with minority businesses for the early 1980s is estimated to be over 53 billion per year with no letup anticipated

5、in the next decade.Promising as it is for minority businesses, this increased patronage poses dangers for them, too. First, minority firms risk expanding too fast and overextending themselves financially, since most are small concerns and, unlike large businesses, they often need to make substantial

6、 investments in new plants, staff, equipment, and the like in order to perform work subcontracted to them. If, thereafter, their subcontracts are for some reason reduced, such firms can face potentially crippling fixed expenses. The world of corporate purchasing can be frustrating for small entrepre

7、neurs who get requests for elaborate formal estimates and bids. Both consume valuable time and resources, and a small companys efforts must soon result in orders, or both the morale and the financial health of the business will suffer.A second risk is that White-owned companies may seek to cash in o

8、n the increasing apportionments through formation of joint ventures with minority-owned concerns. Of course, in many instances there are legitimate reasons for joint ventures; clearly, White and minority enterprises can team up to acquire business that neither could acquire alone. But civil rights g

9、roups and minority business owners have complained to Congress about minorities being set up as “fronts” with White backing, rather than being accepted as full partners in legitimate joint ventures.Third, a minority enterprise that secures the business of one large corporate customer often run the d

10、anger of becoming- and remaining-dependent. Even in the best of circumstances, fierce competition from larger, more established companies makes it difficult for small concerns to broaden their customer bases: when such firms have nearly guaranteed orders from a single corporate benefactor, they may

11、truly have to struggle against complacency arising from their current success.1. The primary purpose of the text is toA present a commonplace idea and its inaccuracies.B describe a situation and its potential drawbacks.C propose a temporary solution to a problem.D analyze a frequent source of disagr

12、eement.2. The text suggests that the failure of a large business to have its bids for subcontracts result quickly in orders might causes it toA experience frustration but not serious financial harm.B face potentially crippling fixed expenses.C have to record its efforts on forms filed with the gover

13、nment.D increase its spending with minority subcontractors.3. It can be inferred from the text that, compared with the requirements of law, the percentage goals set by “some federal and local agencies” （line 9, paragraph 1） areA more popular with large corporations.B more concrete.C less controversi

14、al.D less expensive to enforce.4. Which of the following, if true, would most weaken the authors assertion that, in the 1970s, corporate response to federal requirements （line 1, paragraph 2） was substantial?A Corporate contracts with minority-owned businesses totaled $2 billion in 1979.B Between 19

15、70 and 1972, corporate contracts with minority-owned businesses declined by 25 percent.C The figures collected in 1977 underrepresented the extent of corporate contracts with minority-owned businesses.D The $1.1 billion represented the same percentage of total corporate spending in 1977 as did $77 m

16、illion in 1972.5. The author would most likely agree with which of the following statements about corporate response to working with minority subcontractors?A Annoyed by the proliferation of “front” organizations, corporations are likely to reduce their efforts to work with minority-owned subcontrac

17、tors in the near future.B Although corporations showed considerable interest in working with minority businesses in the 1970s, their aversion to government paperwork made them reluctant to pursue many government contracts.C The significant response of corporations in the 1970s is likely to be sustai

18、ned and conceivably be increased throughout the 1980s.D Although corporations are eager to cooperate with minority-owned businesses, a shortage of capital in the 1970s made substantial response impossible.答案与考点解析1. 【答案】B【考点解析】本题是一道中心主旨题。破解本题的关键在于考生是否完全理解本文第一段首句的内容，尤其是第一句中破折号后面的内容。破折号后面的内容和选项B中的 “its

19、 potential drawbacks”是相互吻合的。望考生注意培养捕捉全文中心主旨句的能力。2. 【答案】A【考点解析】这是一道逻辑思维上的反推题，也可以说是逆向思维题。本题反推即逆向思维的信息依据在第三段的最后一句。该句在谈论小的企业，大概内容是“一个小企业的投资要马上在定货中反映出效果，否则其士气和财政前景都将深受影响”。根据小的企业的状况，我们可以推导出大的企业所面临的处境。希望考生加强逆向思维即反推的解题能力。3. 【答案】B【考点解析】本题是一道关键词语的理解题目，其答案信息来源在第一段的尾句，原文当中的 “specific”一词是本题的答案所在。考生要加强对原文中重点形容词和副

20、词的理解。4. 【答案】D【考点解析】这是一道反论题。这种题的关键在于利用原文的信息否定原文所要表达的观点。原文讲“少数民族企业签订的合同金额由1972年的7700万美元升至1977年的11亿美元”。原文所要表达的观点是合同金额的增长。选项D正是利用原文的信息否定了原文所要表达的观点。选项D所表达的信息是变化增长数字背后的不变。这种题属于较难的题型，希望考生加以重视。5. 【答案】C【考点解析】这是一道关键词语理解题。本题的答案信息在第二段的尾句，句中 “letup”一词决定了本题的正确答案是C，因为该词的含义是“停顿，减弱”。考生在备考过程中要尽力扩大自己的词汇量。参考译文最近几年美国少数民

21、族所有的企业可以说是空前的机会和重大风险并存。*活动家早就指出过：黑人，拉美裔美国人，以及其他少数民族难以在生意场中立足的主要原因是他们缺少能得到有规模的订货或与大公司分合同的机会。现在议会以一致意见通过法律，要求企业获得价值50万美元以上的联邦合同后要尽最大可能来寻找少数民族合作者，并且需将他们在此点上的成效如何在政府中存档立案。实际上，一些联邦和地方机构走得更远，它们甚至规定了公共合同有多少比例要分给少数民族公司。企业对此的反应是强烈的。从1977年统计的数据看，与少数民族企业签订的合同金额由1972年的7700万美元升至1977年的11亿美元。预计此金额要在80年代前期达到每年30亿美元

22、以上，在下一个10年中看来也不会停止。尽管这对少数民族企业来说前途光明，这种增加的财源也给它们带来了危险。首先，少数民族企业冒着过快膨胀和财政上力不从心的危险，因为它们大部分是小企业，和大企业不同之外在于它们为履行合同常需要在厂房、人员、设备（以及诸如此类）等上做一大笔投资。如果其后由于某种原因其合同量减少，它们将会遇到潜在的财政危机。对于被要求做正式评估和投标的小企业来说，市场供求情况有可能令人非常沮丧。评估和投标都消耗时间、资源，而且一个小企业的投资要马上在定货中反映出效果，否则其士气和财政前景都将深受影响。第二个危险是有些白人企业想通过和少数民族企业合资也能享受更好的待遇。当然，在许多时

23、候，合资是有正当理由的;显然，白人和少数民族企业可以联合起来做成任何一方都无法单独完成的事业。但是*组织和少数民族企业主已经向议会报怨：少数民族企业常在合资中成为白人操纵者的前台傀儡，而不是平等的合作伙伴。第三，已获得一个大客户的生意的少数民族企业常会有陷入依赖性的危险。即使在最好的环境下，来自更大、更完备的对手的竞争常使一个小企业很难扩展自己的客户;当这样的企业已拥有来自一个客户的近乎稳定的定货时，它们确实需要和眼前的胜利所滋生出的自满做斗争。SAMPLE 2生物学类审题定位题型句间关系题型归纳推导题型段落结构题型The fossil remains of the first flying

24、vertebrates, the pterosaurs, have intrigued paleontologists for more than two centuries. How such large creatures, which weighed in some cases as much as a piloted hang-glider and had wingspans from 8 to 12 meters, solved the problems of powered flight, and exactly what these creatures were reptiles

25、 or birds are among the questions scientists have puzzled over.Perhaps the least controversial assertion about the pterosaurs is that they were reptiles. Their skulls, pelvises, and hind feet are reptilian. The anatomy of their wings suggests that they did not evolve into the class of birds. In pter

26、osaurs a greatly elongated fourth finger of each forelimb supported a winglike membrane. The other fingers were short and reptilian, with sharpclaws. In birds the second finger is the principal strut of the wing, which consists primarily of feathers. If the pterosaurs walked on all fours, the three

27、short fingers may have been employed for grasping. When a pterosaur walked or remained stationary, the fourth finger, and with it the wing, could only turn upward in an extended inverted V shape along each side of the animals body.The pterosaurs resembled both birds and bats in their overall structu

28、re and proportions. This is not surprising because the design of any flying vertebrate is subject to aerodynamic constraints. Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight. In the birds, however, these bones are reinforced more massively by intern

29、al struts.Although scales typically cover reptiles, the pterosaurs probably had hairy coats. T. H. Huxley reasoned that flying vertebrates must have been warm-blooded because flying implies a high rate of metabolism, which in turn implies a high internal temperature. Huxley speculated that a coat of

30、 hair would insulate against loss of body heat and might streamline the body to reduce drag in flight. The recent discovery of a pterosaur specimen covered in long, dense, and relatively thick hairlike fossil material was the first clear evidence that his reasoning was correct.Efforts to explain how

31、 the pterosaurs became airborne have led to suggestions that they launched themselves by jumping from cliffs, by dropping from trees, or even by rising into light winds from the crests of waves. Each hypothesis has its difficulties. The first wrongly assumes that the pterosaurs hind feet resembled a bats and could serve as hooks by which the animal could hang in preparation for flight. The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings. The third calls for high waves to channel updrafts
