阅读“七选五”要求考生根据文章的结构、逻辑、上下文的内容选出相应的五句话填入空白处将文章补充完整，其目的在于“考查考生对文章的整体内容和结构以及上下文逻辑意义的理解和掌握。”

做题时需要明白整篇文章的主旨，文章整体的思路和每一段的用意以及作者写作的意图，理清段落之间和句子之间的逻辑关系也有助于把握文章的整体结构和思路。

【解题策略】1.从意思上判断2.从词汇上锁定线索

关注空白前后的名词和动词，然后在选项中查找它们的近义词、反义词、同义词、同类词等。其次是一些专有名词，比如说数词、代词、时间、年代、地点/名称等。3.从关联词作为切入点

英语的句段之间经常会运用关联词表示过渡和衔接，让文章的思路与更清楚、逻辑更连贯，因此文章中和选项中表示各种逻辑关系的路标性信号词在选择答案时都是很重要的线索。【试题的位置不同，解题策略也不同】1、若问题在段首

（1）通常是段落主题句。认真阅读该段落，根据段落一致性原则，查找相关词或者同义词，从而推测出主题句，找到答案。（2）与后文是并列、转折、因果关系等。着重阅读后文第一两句，锁定线索信号词，然后在选项中查找相关特征词。一般来说正确答案与它后面的一句话的在意思上是衔接的，所以通常情况下，这两句话中会有某种的衔接手段。（3）段落间的过渡句。这时要前瞻后望找启示，即阅读上一段结尾部分，通常正确答案与上一段结尾有机地衔接起来，并结合下一段内容，看所选的答案是否将两段内容连贯起来。【试题的位置不同，解题策略也不同】2、若问题在段尾（1）通常是结论、概括性语句。要注意表示总结的信号词，如therefore,asaresult,hence,thus,tosumup,toconclude,inshort,inaword等词语，选项中也可发现前文的同义词句。（2）与前文是转折或对比关系。此时要注意在选项中查找表示转折、对比的关联词。（3）与前文是并列或排比关系。在这种情况下，通常是该段落要求补全说明本段主题的其他细节。因此根据段落一致性原则，在原文和选项中找到相关的特征词，通常在选项中会出现表示并列/递进关系的关联词或与前文类似的句式结构，或出现同义词等其他信号线索。（4）所选答案是引出下一段的内容。如果在选项中找不出与前文之间的关联，此时可考虑与下一段开头是否有一定的衔接。认真阅读下一段开头几句，看是否与选项的最后一句紧密连接起来。【试题的位置不同，解题策略也不同】2、若问题在段尾
