专题技能突破(8) 阅读理解之主旨大意 【技能讲解】主旨大意题是高考阅读题目考查中必不可少的题目之一，可以利用主 题句来概括标题，抓住每段的首尾句，综合得出文章的大意。特别关注首尾段落，找到文章 的中心。当出现but，however，therefore等词后，特别关注这些被强调的部分。另外， 可以通过排除法得出正确答案。题干中4个选项，经常会出现某个选项是某一段落的意思， 不足以代表全文；还有的选项会是放之四海而皆准的句子，过于宽泛；还有的选项会是偏离 文章主题的意思。总之，如果能够排除太大、太小、太偏的选项，正确答案就一目了然了。 典例剖析 C 1.[2015·江苏高考，篇]Supposeyoubecomealeaderinanorganization.
