“it”的用法（一）

【归纳】it的用法很多，本单元我们主要学习它的基本用法以及它作形式主语或形式宾语的用法。

1. 用作人称代词，指代上文提到的事物、动物、性别不明或没必要知道性别的人。如：“Where’s your car?” “It’s in the garage.”

Her dog was howling at the door, so he let it in.

The baby next door kept me awake. It cried all night.

2. 用作非人称代词，用来指代时间、日期、地点、天气、温度、距离、环境、情况等。如：It was 4 o’clock and the mail still hadn’t come.

It’s quite warm at the moment.

It’s over 200 miles from London to Manchester.

It’s getting very competitive in the car industry.

3. 用作形式主语，真正的主语常为不定式（短语）、动词-ing形式（短语）或名词性从句。如：

It’s impossible for us to get there in time.

It’s always sad saying goodbye to someone you love.

It’s strange that she never mentioned the wedding.

4. 用作形式宾语，真正的宾语常为不定式（短语）、动词-ing形式（短语）或名词性从句。如：

Many people find it hard to stop smoking.

She finds it boring staying / to stay at home.

I find it strange that she doesn’t want to travel.

【辨析】it, one和that

1. it指物时，是明确指上文提到的那个事物。it可以代替单数可数名词、不可数名词及前面提到的事情或情况。如：

I can’t find my ticket. I think I must have lost it. (it = my ticket)

2. one指前面的名词或名词短语所表示的同类事物中的一个，而不是指同一个事或物。one 既可以代替人，也可以代替物，但只能代替可数名词，其复数形式为ones。如：

The train was crowded so we decided to catch a later one.

Those shoes are too small. We must buy some new ones.

3. that可以代替“the +单数可数名词或不可数名词”，用于特指。that不能代替人，不可带前置定语，但可带后置定语。如：

Are you sure the population of Shanghai is larger than that of Beijing?

The milk here is tastier than that of other places.
