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

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。

从高考题看“It” 用法与考点延伸

从高考题看“It” 用法与考点延伸摘要本文笔者从高考题讲述“It”的用法和考点,及其主要的句型。

关键词高考题用法考点一.It用法透析:1.It可用作人称代词,代替前文出现的事物,也可用以代替指示代词this和that。

2.It作非人称代词,表示时间、日期、地点、天气、温度、距离、环境等。

3. It 用作形式主语或宾语,代替不定式, 动名词或从句4. It 也可用在强调句型中,对谓语动词之外的成分加以强调。

常用句型为:“It is /was + 被强调成分+that (who/ whom)+句子其他成分”二.It 的考点延伸1. it /that /one 的区别(2010陕西卷12). The cost of renting a house in central Xi’an is higher than ____in any other area of the city.A. thatB. thisC. itD. one此题的正确答案为A. This为指示代词,指代下文即将提到的事物;That除作指示代词外,还可指代前面出现的同类名词,相当于the +名词;It指代“同类中的同一物”;One虽指同类但不是同一物体,表示“某一个”的含义。

2. It应用的强调句型与定语从句、状语从句或名词性从句混搭判断是否强调句型的方法是将强调结构去掉之后,如句子表述仍完整,则为强调句型,反之则不是。

(07山东)---Where did you get to know her?--- It was on the farm ____ we worked.A. thatB. thereC. whichD. where此题的正确答案为D。

这是一个省略句,完整表达应该为:It was on the farm ______ we worked that I got to know her。

分析句式应该为定语从句,farm在从句中充当的成分为地点状语,选择关系副词where。

one只能代替可数名词,其复数形式是ones;that用来指代前面同名异物的名词,指的是同类中的一个,属于特指,相当于“the+名词”。

that既能代替不可数名词,也能代替可数名词,其复数形式是those。
