2021届人教版高三英语课件：强调句（12张ppt）

(共12张PPT)
特殊句式：强调句
1. 强调句的基本句型
It is/was＋被强调部分＋that/who＋句子剩余成分
(1)强调人时可用who/that来连接，强调事物时用that。
所强调的可以是单词、短语，也可以是从句，但结构必须完整。被强调的成分可以是主语、宾语和状语，但不能是定语或谓语。
It is I who/that am right.
我才是对的。
It was him that/who/whom we met at the school gate.
我们在学校门口遇到的是他。
It was because her mother was ill that she didn't go to work.
她之所以没来上班，是因为她母亲病了。
(强调主语)
(强调宾语)
(强调状语)
(2)这种强调句的一般疑问句只需把is(was)提前。
Was it in 1939 that the Second World War broke out
第二次世界大战是在1939年爆发的吗？
Is it Professor Wang who teaches you English
教你们英语的是王教授吗？
(3)它的特殊疑问句只需在一般疑问句前加上特殊疑问词。
Who was it that broke the window
打破窗户的是谁？
When was it that you called me yesterday
你昨天给我打电话是什么时候？
(4)not...until...的强调句形式：It is/was not until＋被强调部分＋that＋其他成分。
He didn't go to bed until 11 o'clock last night.
→It was not until 11 o'clock last night that he went to bed.
他昨晚直到十一点才睡觉。
It was not until he took off his dark glasses that I realized he was a famous film star.
直到他摘下墨镜时，我才认出他是一位著名的影星。
注意：判断一个句子是强调句型还是其他句型，最简单的方法就是“还原法”，即去掉强调句型的特有结构It is/was...that/who...，若去掉这个结构后句子仍然成立，那该句型便是强调句型。否则，就可能是其他句型。
(1)It was he who did all the cleaning.可以看出，去掉画线部分的词，句子仍然成立，故该句为强调句型。
(2)It is a pity that he has failed again.此句中的画线部分若去掉，句子就不成立了，故该句不是强调句型。而是it作形式主语，that引导真正主语的句型。
2. 用助动词强调谓语
如果要强调时态为一般现在时或一般过去时的肯定句中的谓语动词，我们在该动词前加助动词do，does或did。
Many of the films are from the USA，but we do give awards to films from other countries.
许多电影来自于美国，但我们的确也给其他国家的影片颁奖。
He did come to see you last Sunday，but you were out.
他上周日的确来看过你，但是你出去了。
