11、确定排除理由，最终确定答案。 解题方法：快速阅读全文要点词句，包括首尾段，首尾句以及独立成段的句子和文章中带转折词的句子，目的是掌握文章的主要内容，了解大意。1. 同词出现法。词汇同现是指属于同一词汇或者跟此词汇相关同一领域的词汇在文章中共同出现，达到语义衔接的目的。你可以在选项中找到与此词汇最接近的词，从而达到快而准。一般来说，上下文中词汇联系越接近，上下文的衔接关系越紧密。2. 词汇复现法。复现，是保证文章前后衔接而经常使用的一种写作手段，即作者在文章上下文不同的位置对同一个概念进行重复描述。复现关系，主要是指同义词复现、近义词复现、反义词复现等。双保险：上下文再核实一下3. 代词线索。英语表达中代词出现的频率极高，代词的作用无非是指代前面提及的名词或形容词概念，巧妙利用这样的指代关系和根据代词的单复数差异可以准确而快速地解题。4. 逻辑关系衔接。解答议论文体的阅读填句题,首先要把握好所论述的中心问题.通常所挖空缺与选项都以一条主线为主。其次,此类文章中经常出现一些逻辑关系词,对于理解文章与判定答案很有帮助。解题技巧：速读全文，关注每段首尾句，了解大意知主题浏览选项，理解全篇逻辑关系,找出关键词运用上下文所重复的关键词推断利用同义词和近义词关系利用词的上下义关系利用反义词、过渡词关系理清结构与逻辑关系，确定答案【板书设计】【教后反思】 / 文档可自由编辑打印
