2、广泛，所以阅读时，首先要能够掌握文章的大意。2. 弄清楚说明的顺序把握了说明顺序，就能准确把握文章的脉络，加强对整篇文章的理解。3. 把握文章的组织结构，理清事实细节把握语篇特征对理解文意与答题极为有利。说明性的文章一般都是一篇完整的、意思表达清楚的、逻辑比较严密的短文。在阅读这类文章时，我们一定要仔细研读文章的开头和结尾，从主题句着手，找出支持句，然后寻找文章的结论。这时，我们还要特别注意，不要被表面的一些细节所迷惑，我们在理解细节的基础上，还要斟酌文字的内涵意义，从而对文章进行深层次的理解。4. 注重上下文语境应逐句精读短文，逐题分析选项，对特定的语境作深入的理解，克服思维定势，根据全文大

3、意和词不离句、句不离文的原则逐项填空。5. 熟练做题方法，遵循四个原则：（1）上下一致。每个选择项必须从全文出发，从大处着手，避免孤立地分析每一空格，造成误选。（2）语法正确。从语法地角度去考虑动词的时态、语态以及词类用法。（3）逻辑合理。在完形填空题中，逻辑推理非常重要，有时每个选择项从语法上讲都正确，但是有的是不合语境逻辑的。（4）符合搭配。英语中固定搭配很多，需要熟练掌握，才能做好此类题目。Part 2对点解密【真题对点析】1（2012上海高考真题）People on a college campus were more likely to give money to the March

8、 degree of 19 between the potential helper and the person in need is also important. For example, people are more likely to help a stranger who is from the same country rather than a foreigner.

D考查语境选词。这种基因几乎100%由蚊子后代继承而且在三代内遗传。method方法;country国家;variety不同种类,多种式样;generation代,一代。故选D。17. A考查形容词辨析。科学家们培育转基因蚊子的目的

31、是造福人类,因此这种新的基因是有用的(useful)基因。doubtful怀疑的;thoughtful 体贴的;wonderful绝妙的,精彩的。18. C考查名词辨析。研究者称这些调研结果为将同样的方法用于其他种类的蚊子提供了希望,故选C。belief信念,opinion观点,fact事实。19. A考查名词辨析。此处指和印度蚊子相对应的其他种类(species)的蚊子。species种,物种,member成员,drug药,surroundings环境。20. D考查从属连词的用法。此处表示尽管不是解决疟疾问题的唯一方法,但将会是一种有用的附加武器,上下文之间有逻辑上的让步关系,故选D。【真

32、题对点析】2(2016上海)In the 1960s, Douglas McGregor, one of the key thinkers in the art of management, developed the now famous Theory X and Theory Y. Theory X is the idea that people instinctively 1 work and will do anything to avoid it. Theory Y is the view that everyone has the potential to find satisfa

33、ction in work.In any case, despite so much evidence to the 2 , many managers still agree to Theory X. They believe, 3 , that their employees need constant supervision if they are to work effectively, or that decisions must be imposed from 4 without consultation. This, of course, makes for authoritar

34、ian (专制的) managers.Different cultures have different ways of 5 people. Unlike authoritarian management, some cultures, particularly in Asia, are well known for the consultative nature of decision-making all members of the department or work group are asked to 6 to this process. This is management by

35、 the collective opinion. Many western companies have tried to imitate such Asian ways of doing things, which are based on general 7 . Some experts say that women will become more effective managers than men because they have the power to reach common goals in a way that traditional 8 managers cannot

36、.A recent trend has been to encourage employees to use their own initiative, to make decisions on their own without 9 managers first. This empowerment (授权) has been part of the trend towards downsizing: 10 the number of management layers in companies. After de-layering in this way, a company may be

37、11 with just a top level of senior managers, front-line managers and employees with direct contact with the public. Empowerment takes the idea of delegation (委托) much further than has 12 been the case. Empowerment and delegation mean new forms of management control to 13 that the overall business pl

38、an is being followed, and that operations become more profitable under the new organization, rather than less.Another trend is off-site or 14 management, where teams of people linked by e-mail and the Internet work on projects from their own houses.

42、，他们为逃避工作可以做任何事情。故D项正确。2. A to the contrary相反的；to the degree在某种程度上；to the extreme走向极端。此处是说，无论如何，尽管很多证据与这个理论相反，很多管理人仍然同意X理论。故A项正确。3. B 由后面的例子他们认为如果要员工效率高，就需要给予他们不断的监督可知此处是举例说明。故B项正确。4. D 根据后句可知，此处是说，他们的决定是来自上而下的，没有任何商量的余地。故D项above上面的正确。5. C 根据前段可知本文讨论的是管理学的理论，此处是说，不同的文化中有不同的管理人的方法。故C项正确。6. B refer to提

43、到，谈到；contribute to做贡献，导致；object to反对；apply to适用于。此处是说，亚洲人使用的是协商式的管理方法，所有人都被要求对管理的过程作出自己的贡献。故B项正确。7. A agreement同意；practice练习，做法；election选举；impression印象。此处是说，亚洲人使用协商式的管理方法，这种方法是建立在共同协商的基础上的，西方人也想模仿这样的管理方法。故A项正确。8. D 根据前半句.women will become more effective managers than men.可知有些专家认为女性比男性管理更高效，因为女性更有亲和力

44、，比男性管理人更容易与别人达成一致的目标。故D项正确。9. A 根据前句. encourage employees to use their own initiative. （鼓励员工使用自己的首创精神），也就是说在作出决定的时候不用先请示上级经理。故A项正确。10. C 根据the trend towards downsizing（缩小规模的趋势）可知，也就是要减少管理层的数量，可以直接作出决定而不需要请示上级，故动词reduce减少符合语境。11. B be honored with被授予；be left with留下，剩下；be crowded with挤满；be compared wi

45、th与相比，通过这种方法，公司只剩下高层管理者和与公众直接联系的一线管理人，省略了很多中央环节，提高了管理的成效。故B项正确。12. B economically经济地；traditionally传统地；inadequately不充分地；occasionally偶尔地。根据后句Empowerment and delegation mean new forms of management control可知授权管理是一种新型的管理方法，与传统的管理模式不一样。故B项正确。13. D deny否认；admit承认；assume假定，设想；ensure保证，确保。授权管理是一种新型的管理方法，省略了中央管理环节，保证了整个商业计划被采用。根据句意可知D正确。14. A virtual虚拟的；ineffective无效果的，低效率的；day-to-day日常的；on-the-scene现场的。根据后句where teams
