英语语法：强调句结构









常考的强调句结构是
it
引导的句子。




It is (was)
被强调部分
+ that (who) +
句子其他部分。





此结构强调的成分仅限于主语，宾语和状语。






It is from the sun that we get light and heat.





It was not until I had read your letter that I understood
the true state of affairs.



典型例题



1
）
It was last night ___ I see the comet.


A.
the time
B.
when
C.
that

D.
which




答案
C.
强调句的结构是：
It +be +
强调部分
+ that (who) +
主谓
句。

强调句的连词只有两个，
that
和
who
。当强调的部分是人，且为句子的
主语时，才用

，其余用
that
。




原句：

My father did the experiment in the lab yesterday
evening.



强调主语：
It was my father who did the experiment in the lab
yesterday evening.



强调宾语：
It was the experiment that my father did in the lab
yesterday evening.



强调时间：
It was yesterday evening that my father did the
experiment in the lab. (
注意不用
when)



强调地点：
It was in the lab that my father did the experiment
yesterday evening.


2
）
It is ten years ___ Miss Green returned to Canada.


A. that
B. when
C. since
D. as




答案
C.
考点是连词用法。

本题易误选为
A. that.
其实本句不是强调
句。若是，去掉
It

be… that
还应是一个完整的句子。而本句去掉
'It
is…that
'
，只剩下
ten years Miss Green returned to Canada.
不成句。因
此本句不是强调句。




It is /was +
时间+ since…

其中
is<---> has been
was <--->
had been.
