分析： 在上面例句中若去掉It was... when / before / since
等后，句子结构就不完整，所以不是强调句。

三、强调句型几注意
首先，我们按强调句的语序来总结强调句的五项注意：
1. 句首词用“It”，不能用“This”，“That”等。
2. be动词的形式是is或was，不能用复数形式are或were。
若原句的谓语动词用了现在时或将来时，则用is;若原句
的谓语动词用了过去时或过去完成时，则用was.
Eg:（3)It_C__the Chinese women that___a great role in the
socialist construction.
A is;plays B are;play C is;play D are;plays
（4)_A__all these exercises____all of us can do tomorrow.
A It is;that
B It was;that
C They are;which D It will be;that
A. that B.what C.which D.when
5. 主谓一致问题
被强调的主语要和 that后面的谓语动词在数上保持一致。
who. 特 别 注 意 当 强 调 部 分 是 时 间 状 语 或 地 点 状 语 时 ， 不 能 用
when或where。
Eg:（7）It was on Oct 1st, 1949 that People’s
Republic of China was te __A______ he told me the news.(MET'88)
②It is on the hillside that we plant trees every year. ③It was because of bad weather that the football match had to be put off.(Shanghai 2003, spring)
分析：去掉It is / was... that / who 句子后结构仍然完整，
句意仍明确，都是强调句。 ④ It was 9 o'clock when we came back． 我们回来时是九点钟。 ⑤ It was 3 hours since we had come back． 我们回来已三个小时了。
A. which B. that
C. where D. the one
② It was our teacher ____B____did the experiment in the lab last night.
A.whom B. that C. which D. where ③ It was ten years ago____A____ Miss Gao returned to

一，基本结构：
It is(was)+ 被强调部分+ that（强调部分是人时也可用 who/whom） +其他成分
Eg: We elected him monitor at the class meeting yesterday.
主
宾 宾补
地状
时状
It was we that /who elected him monitor at the class
3. 被强调的部分如果是代词，强调主语用主格，强调宾语
用宾格。如：
（5）It is him that/who /whom I met in the street yesterday.
（6）It is I who/that am wrong.

4. 连接词一般用that，当强调部分是人时，既可用that也可用

二、强调句型的判断 把“It, be，that”去掉，如果剩余部分句子结构仍然完
整（被强调部分要还原到原位置），那么这个句子就是强 调句；如果句子不完整，则不是强调句。如： （1）①It is he who / that often helps me with my English.
meeting yesterday.
（强调主语）
It was him that /whom we elected monitor at the class meeting yesterday. （强调宾语）
It was monitor that we elected him at the class meeting
