中考英语复习: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 ofChina 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。

    You can’t make it to the other shore in this weather.  天气这么恶劣,你可到不了对岸。

    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.  好的,让我们约定下星期日碰头吧。

    2. as it is

    ①用于句前,表示“事实上”。如:

     I thought he would get better, but as it is he is getting worse. 我认为他会好转,但事实上他一直在恶化。

    ②用于句末,表示“照原样”。如:

      Leave the chair as it is.   那椅子照原样放着,别动。

    3. as it were可以说;在某种程度上

    He is, as it were, a walking dictionary.  他好比是一本活字典。

    4. see to it that ... 注意;留神;负责

    See to it that everything is ready.    注意一切都要准备就绪。
