What is the text mainly about?,3推理判断题 推理判断题考查学生是否能将说明对象举一反三，进行一般的推理。 典题示例 What made the author feel cold？ (2012新课标阅读理解C) We can conclude from Samsungs statements that_. (2012山东阅读理解D),4细节理解题 说明文中考查的细节理解题主要检查考生是否能够对文章描述的事实作出判断、归纳或总结。 典题示例 The Mangrove Rivulus is a type of fish that_. What did the scientists do to find out if the enose worked? According to Paragraph 1，a persons emotion may be affected by_.,二、策略聚焦 1明确说明对象，找出主题句 阅读描述事物类的说明文，首先从整体入手，把握文章的说明对象。阅读事理性说明文时，要先弄清文章说明了什么事理。可以通过题目或段落主题句来明确说明对象。不少说明文的题目都表明了说明对象，有的题目在指出说明对象的同时，还指出了其特征。一般来说，说明文每段的主题句常出现在段首或段尾。有的说明文没有明显的主题句，阅读时更需要细心琢磨，从中加以提炼。,2逐段概括要点，理清说明顺序 逐段概括要点时要重视首尾句的作用，重视给概念下定义或解说性语句的作用。阅读时可以把这些语句勾画出来。在逐段概括要点的基础上，用“同类合并”的方法，把全文划分为相对独立的几个部分，概括出每部分的大意，把每部分的大意依次连接起来，便能比较清楚地显示出全文的说明顺序了。,3整体感知，把握中心 整体把握文章结构需要分析文章段落之间的关系，弄清它们之间是并列、递进还是总分关系，是由现象到本质，还是由个别到一般，或是从原因到结果。把握中心即归纳该篇说明文中的说明对象具有怎样的特征或该篇说明文阐释了怎样的事理。在理清说明顺序、把握文章结构后，再归纳说明文的中心内容也就不难了。,.特别关注攻克长难句 1The research finds out that babies who are fed on demand do better at school at age 5,7,11 and 14，than babies fed according to the clock.
