1、锁定上下逻辑锁定上下逻辑攻克攻克高考英语高考英语阅读阅读“七选五七选五”怎么考近年来，“7选5”以考查细节理解为主，以说明文和议论文居多。该题型要求考生从整体上把握文章的逻辑结构和内容上的前后联系，理解句子之间、段落之间的关系，对诸如连贯性、一致性等语段特征有较强的意识和熟练的把握，并具备运用语法知识分析理解长难句的能力。其选项一般分为三类：主旨概括句、过渡性句子或注释性句子。考法1考查对文章的整体内容和结构的理解和掌握(1)描述性结构：主要介绍人物、事物、问题或倾向的特点；对人物的描述，如传记，包括人物的身体特征、家庭背景、成长过程、个性爱好、成就贡献等内容，时间、地点往往是出题重点；(2)

2、释义性结构：解释某一理论、学科、事物，主要用举例、类比等方法进行阐述；(3)比较性结构：把两个人或事物的功能、特点、优缺点进行对比；(4)原因性结构：主要分析事物的成因；(5)驳斥性结构：先介绍一种观点，之后对其进行分析、评论或驳斥，最后阐明自己的观点。考法2考查对上下文逻辑意义的理解和掌握语段的句际关系可分为因果、并列、转折、层递、总分等类别。常考查的连接性词汇有：(1)因果关系：so，therefore，thus，hence，accordingly，consequently，as a result等；(2)并列关系：first，second，third.；firstly，secondly，

3、thirdly.；first，next，then.；in the first place，in the second place，.；for one thing，for another.等；(3)转折关系：but，however，nevertheless，nonetheless，still，though，yet，in spite of，on the contrary，by contrast，conversely，otherwise等；(4)层递关系：also，further，furthermore，moreover，in addition，whats more，not only.but als

4、o.等。怎么学针对该题型的考法，在平时的阅读训练中，注意把握文章的体裁。分析篇章结构，把握全文脉络。语篇通常由段落构成，所以分析篇章结构包括两个层次：一是分析段落之间的层次，也就是语篇层次；二是分析每个段落内部的层次，即句际层次，尤其是选项与前(后)句之间的逻辑关系等。另外，在平时的阅读训练中，培养自己辨别语境线索的能力。语境线索主要指反映上下文关系的衔接手段，如篇章结构、词语重现、逻辑关系、连接、指称、同构等。词语重现是指词语的重复出现，但这里不是指词语的简单重现，而是指某一词语可能以不同的词性、数、格、时、态等形式出现，如read，reading，reader，readers；还可能是以同

5、义词、近义词甚至反义词等形式出现。逻辑关系是事物之间内在的、必然的联系，包括时间先后关系、空间位置关系、因果关系等。连接是指用连接词或连接语表明上下文之间的逻辑关系，如and，however。指称是指用代词替代前文已出现的人物、事件、物品等，如he，she，they。同构是指上下文使用了相同或类似的句式。怎么解步骤1通读整篇文章对文章进行快速浏览，把握段落语脉，寻找主题句，理出文章的中心，掌握文章结构及文章的写作内容。注意文章的开始与结束段落，尤其是文章首段及末段的末句，因为“开门见山”与“结尾总结”为常见的写作方式。首段的末句很可能是全文的主题所在，并简要指出文章的写作思路，有时甚至会以提纲

6、的形式进行呈现。步骤2详读段落在短时间内，找出每段内容的关键词，注意关键词之间的关系。将所有句子按意义分出层次，再分析各层次之间的关系，明确各段的主题句或主旨大意。步骤3定位选项明确各备选选项的含义，抓住其关键词语，根据文章整体结构与具体内容，将选项填入文中。填写时尤其要注意各选项的句子的衔接手段及句中的衔接标志词。步骤4通读复检将所选答案代入文中，再次通读全文，重点检查逻辑关系。步骤5注意一些词类的用法(1)注意代词。代词是用来指代名词或句子的。做题时，一定要注意句中出现的人称代词或指示代词，然后通过代词在句中所作的成分推断出它指代的成分的类型，进而从选项中找到答案。(2)注意特殊疑问词。如

7、果选项中或题空前出现特殊疑问词，一定要把这句话仔细读几遍，因为针对不同特殊疑问词的回答方式是不一样的。比如对why的回答，要有because等表示原因的词；对when的回答，要有表示时间的状语；对where的回答，要有表示地点的状语；对how的回答，要有表示方式或程度的状语等。(3)注意连词。如表示转折的连词有but，however，yet，though等；表示并列关系的连词有and，or，on one hand.on the other hand等。步骤6确定排除研究多余选项，确定排除理由，最终确定答案。【典例剖析1】体裁：说明文话题：人的寿命词数：267时间：7根据短文内容，从短文后的选项
