it的用法(Ⅱ) 1.it 在强调句中的用法 it 可用来对句子谓语以外的某一成分进行强调，强调句的 基本句型为：It+动词be+被强调部分+who(m)/that+其它部 分。被强调部分指人，引导词用who/that均可，被强调部分是 人，并且在句中作宾语时，可用whom/who/that引导。强调其 它部分，一律用that。被强调的部分是原句的主语时，who/that 之后的谓语动词在人称和数上与该主语一致。 (1)It was Jane who paid for the meal yesterday.(=It was Jane and not another person.) 昨天的饭钱是简付的。 (2)It was the meal that Jane paid for yesterday.(=It was a meal and not something else.) 简昨天付的是饭钱。

2.强调结构和主语从句句型(It+be+adj./n.+that其它部 分)的区别。 (1)强调结构可以翻译成“正是……”或“就是……” (2)含有主语从句的句子删掉It be...that/who,则原句在结构 上和意义上均不成立，而强调结构若去掉结构标志后，原句在 结构上和意义上仍然成立。 It is I that/who am your true friend. 我才是你真正的朋友。 (这是强调句，去掉It is...that/who后，句子仍然成立。) It is necessary that you should master at least one foreign language. 你有必要掌握至少一门外语。 (It作形式主语，代替后面由that引导的主语从句，去掉It is...that后，句子不能成立。)

3.强调句型和It+动词+一段时间+ before/when/that/since句型的区别。 (1)强调句型：It+is/was+被强调部分+who(m)/that+其 它部分。 It was not until he came back that his mother went to bed. (2)It is+时间段+since 从句(一般过去时/过去完成时)。 It's years since we enjoyed ourselves so much. 我们已有好多年没有这么开心过了。 (3)It was/will be+时间段+before 从句(一般过去时/ 一般现在时). It was not long before he joined the Party. 不久，他就入了党。

(4)It was+时间点+when从句(一般过去时) It was 12 o'clock when he came back to school. (这不是强调句。it指时间， when引导时间状语从句。)

比较：It was at 12 o'clock that he came back to school.(这是强调句，强调时间状语at 12 o'clock,去掉It was...that,句子仍然成立。) 4.对于特殊疑问句强调的句式是“疑问词+is/was+it +that+其它部分”。 What is it that Rosa has found in the living room? 露莎在起居室里发现的是什么？

I don't know what it is that Jimmy has done in his study. 我不知道吉米在书房里干什么。 Do you still remember where it was that you first came across Paul three years ago? 你还记得三年前是在哪儿第一次见到保罗的吗？
