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.
