“It” 重点用法归纳
一、it在特定句型中的运用
1. It was/will be long(one week/two years ...)+before从句
此句型可译为“很久(一周/两年后……)才……”。如:
It was long before he came back.
很久以后他才回来。
It will not be long before we meet again. 不久我们就又会见面。
2. It is/has been/was + some time + since从句
此句型可译为“自从……以来已经有多长时间了”。如:
It is / has been more than fifty years since the People’s Republic of
China was founded.
中华人民共和国成立已经有五十多年了。
It was three days since he had fallen ill. 他生病已经有三天了。
注意:①如果since从句中的谓语动词为延续性动词时, 应译为“自从不……以来已经有多长
时间了”。如:
It is / has been seven years since I taught in this school.
我离开这所学校已经有七年了。
②时态的把握:如果主句运用的是一般现在时或现在完成时,那么since引导的从句用一般过
去时;如果主句运用的是一般过去时,那么since引导的从句常用过去完成时。
3. It + be + the +序数词+ time + that从句
此句型可译为“是某人第几次做某事了”。如:
It is the first time that I’ve spoken in public.
这是我第一次公开发言。
注意:如果主句是一般现在时或一般将来时,从句用现在完成时;如果主句是一般过去时,从句用过去完成时。
4. It +be +具体时间+ when ...
此句型可译为 “当某事发生时,时间是在……”。如:
It was 11:00 when they arrived at the factory. 他们到达工厂时是11点。
请比较:①It will be July 1 ______ we meet again.
A. since B. that
C. before D. when
②It is on July 1 ______ we will meet again.
A. since B. that
C. before D. when
分析:答案分别选D和B。第一题填when,表示“当……时候”;第二题很显然是对时间状语的强调,因为把It is和that去掉,该句仍然成立,即:We will meet again on July 1.
5. It +be +(high/about)+time that从句
此句型可译为“早就该有某事或做某事了”。如:
It’s high time that you stopped fooling around and started looking for a
job.
你可别再游手好闲了,也该找份工作了吧。
注意:该句型that从句中谓语动词多用一般过去时态。
二、it的几个特殊用法
1. make it
①表示“成功;做到;赶上”。如:
The train is due to leave in five minutes we will never make it .
火车再有五分钟就开了,我们是绝对赶不上了。

②表示“规定时间”。如:
－Shall we meet next week
下星期我们碰一次头好吗
－Yes. Let’s make it next Sunday.
