找到中心思想

时间: 未知2 阅读理解
  一个句子、一段文章虽然能提供许多信息,但它的中心意思通常只有一个。其它细节都围绕这个意思,说明这个意思。要提高阅读速度有一个最根本的要求,就是要找到并抓住这个中心意思。抓住了中心意思才能正确地理解句子、段落或通篇的基本内容。下面几组词,每一组都有一个中心词:
  A.apple fruit orange
  B.animal cat dog bird
  c.green red yellow color
  D.chair table furniture couch
  E.nurse profession teacher lawyer
  段落的中心意思与句子的中心意思是类似的。一般有两种情况:一种是表明的中心意思,另一种是隐含的中心意思。表明的中心意思常常用一个或几个句子来表示,隐含的中心尽想需要读者用自己的话去概括、归纳整篇或整段的含义。
  要想在考试中在阅读理解部分取得高分,首先必须学会寻找中心思想、抓住中心思想,特别是段落的中心思想。主题句的位置比较灵活,有的在段首。有的在段末,有的则居段中,但主题句在段首的比较多。例如:
  As the sun went down , the scene from the bridge was beautiful, It had been a perfect day. Up and down on either side of NY the bright blue water lay gently rippling, while to the south it merged into the great bay and disappeared toward the sea. The vast cities spread away on both sides. Beyond rolled the hilly country until it was lost in the mists of the sky. All up and down the harbor the shipping, piers , and buildings were still gaily decorated. On the housetops of both Brooklyn and NY were multitudes of people.
  主题句就是第一句。其他的句子只是细节,都是解释、说明第一句的。
  不论主题句在句首也好,在句末也好,都是用一个完整的句子表达这一段的中心意思的,在这一类的文章中,识别主题句进而抓住中心意思是比较容易的,比较困难的是识别、寻找隐含的中心意思,例如:
  Tennis is not a difficult game to play , and you do not need a lot of equipment to play it. There must be two or four players. Each player should have a comfortable tennis racket. The players will also need some tennis balls. Of course, it is necessary to have a tennis court.
  这一段的中心意思没有用主题句表示出来,而是包含在这一段的上下文中,需要我们用自己的话进行概括、归纳。可以看出,这一段的中心意思应该是:Players need a court,rackets,and tennis balls。
