it用于强调句式
太和中学：袁晓娟
1．it强调结构的概述
it用在强调结构中，为了强调句子的
某一成分(通常为强调主语、宾语和状 语 )。 其结构为:“It is/was＋被强调部分＋

that＋句子的其余部分”。
2．it在强调句中的应用
(1)强调主语 eg:
I met Tom in the street last week. →It was I that met Tom in the street last week. 正是我上周在大街上遇到了汤姆。
Ⅲ.根据提示翻译句子
1．正在打电话的是张教授。(强调
主语) 【答案】It is Professor Zhang who is talking on the phone. 2．病人需要的是更好的食物和更多 的阳光。(强调宾语) 【答案】It is better food and more sunshine that the patient needs.
3．奥林匹克竞赛是从什么时候开始的？
(强调时间状语) 【答案】When was it that the Olympic competition started? 4．第二十九届奥运会在中国举行。(强 调地点状语) 【答案】It is in China that the 29th Olympic Games are held.
→It
was Tom that/who/whom I met in the street last week.
6．用这一强调句型时，还要注意以下几点:
(3)如果强调的是主语时，that或who之后
的谓语的人称和数要与被强调的主语保持 一致。 It is only I who/that am willing to go to the cinema. It is he who/that is to blame.
3．Because
he was seriously ill， he didn’t come to school yesterday. 【答案】It was because he was seriously ill that he didn’t come to school yesterday.
注：去掉it is/was与that，剩余部分结构完整、句 意明确，则为强调句型，否则不是。 →It was obvious that he was right. 注：这句话就不能称为强调句式，因为去掉it is/was与that，剩余部分结构并不完整。
4．it强调句结构中的疑问句
(1)强调句的一般疑问句:只需is/was 提前。

6。用这一强调句型时，还要注意以下几点：
(6)强调句型的时态要依原句的时态而定，即原
句为过去的某种时态，强调句中就用 was ；原 句为现在或将来的某种时态，强调句中就用 is。
I met Tom in the street last week. →It was I that met Tom in the street last week. He is to blame. →It is he who/that is to blame.
(5)使用这一强调句型时，需注意否定转移
