It在强调句中的用法考点透视
It在强调句中的用法考点透视高中高三英语教研组It一词是高中英语中考查比较频繁的一个词，it含义简单却用法众多，透过近几年的高考试题我们可以看出，各省份高考试题对it的考查十分频繁，尤其是关于it在强调句中的用法的考查更是成为了考查的热点。
以下本文结合近几年高考试题对it在强调句中用法的考查，来对it在强调句中的用法进行一个详细的解析和回顾，通过对照高考真题，归纳讲解it在强调句中的用法，以方便同学们进一步系统牢固地掌握有关it在强调句中的种种用法：1．强调句型的基本结构是：“It is (was) +被强调部分+ that (who) + 其它”被强调部分如果是指人则引导词可以用who，其余情况都用that。
强调句也可以有变体形式，例如：It may have been at the Christmas that John gave Mary a handbag.It might have been John who gave Mary a handbag.强调句的判定方法是：将强调句中的it is/was以及连接词that或who去掉，如果句子仍然成立，成分仍然完整，则说明该句是强调句。
强调句理论上可以强调除谓语以外的任何成分，但是在正式英语中，强调句也一般不强调表语（或叫做主语补足语），例如：It is I who am to blame. （强调主语）It was a new pen that Mother gave me.（强调宾语）It was in the classroom that I left my umbrella.（强调地点状语）It is at eleven that the train leaves.（强调时间状语）It was just as he ordered that I acted.（强调方式状语）It was because he was in trouble that I tried my best to help him.（强调原因状语）It was chairman that they elected him.（强调宾语补足语）相关高考试题：（1）It was after he got what he had desired _______ he realized it was not so important.（06年高考辽宁卷第35题）A. thatB. whenC. sinceD. as（2）David said that it was because of his strong interest in literature _______ he chose the course.（06年高考上海春季招生卷第35题）A. thatB. whatC. whyD. how（3）It is what you do rather than what you say _______ matters.（05年高考天津卷第9题）A. thatB. whatC. whichD. this（4）It was only with the help of the local guide ________.（05年高考上海春季招生卷第37题）A. was the mountain climber rescuedB. that the mountain climber was rescuedC. when the mountain climber was rescuedD. then the mountain climber was rescued 答案：（1）A（2）A（3）A（4）B2．强调句的疑问句形式：强调句的一般疑问句：Is/Was it + 被强调部分 + that /who强调句型的特殊疑问句：疑问词 + is/was it + that/who（1）I just wonder ____ that makes him so excited.（06年高考山东卷第32题）A. why it doesB. what he doesC. how it isD. what it is（2）—____ that he managed to get the information?—Oh, a friend of his helped him.（05年高考山东卷第31题）A. Where was itB. What was itC. How was itD. Why was it答案：（1）D（2）C3．It is/was not until…that…表示“直到……时候才”，也是一个强调句型。
“it”引导主语从句和“it”做形式主语还有强调句型的区别分别是什么？
“it”引导主语从句和“it”做形式主语还有强调句型的区别：it引导的主语从句，形式主语就是it，真正的主语在句子的后面，通常是to do的不定式短语。
而强调句的结构
it is/was+被强调部分+that/who+句子其余部分，结构词it is/was和that/ who都是没有实际意思的，只是构成句子结构的词而已。
这个强调句只能强调名词和代词，也就是主语和宾语，不能强调其他句子成分。
主语从句：It is kind of you to help me with my housework.
强调句：It is you who help me with my housework.
主语从句中it做形式主语的常见句型：It+be+形容词+主语从句，如：It is u ncertain whether he can come to Jenny’s birthday party or not. It + be + 名词词组+ 主语从句，这类名词有：a fact, a pity, a shame, an honour，a question等，如：
It’s a pity that you missed the exciting football match.
It remains a question whether he will come or not.
It + be + 过去分词+ 主语从句，这类过去分词有：announced, believed, expected, hoped, decided, reported, said, shown等，如：It is reporte that 16 people were killed in the earthquake.。
