  It 的用法很广,高考考查频率较高,下面将其主要用法讲析如下:
  1. 指代时间、天气、距离、自然现象等无生命的东西。如:
  1. It is 10 kilometers from my home to the school.
  2. It is Christmas today.
  2. 指代未知的人或说话人心中所指的人或用以明确身份。
  1. I’m sorry I didn’t know it was you.
  2. —Who’s knocking at the door? —It’s me.
  [Practice]
  [2014-25全国大纲卷] —Who’s that at the door? —_____ is the milkman.
  A. He B. It C. This D. That
  3. 用于强调句型“it is/was+被强调部分+其它”中。如:
  1. [重庆卷改编] It is not who is right but what is right that is of importance.
  2. [2004湖北卷改编] It was not until midnight that he went back home after the experiment.

  [全国卷改编] I don’t mind her criticizing me, but _____ is how she does it that I object to.

  2. [全国高考题改编] The porter bought a new house but it will need a lot of work before they can move in.
  注意:it作这种用法时,与that, one的区别。that 用于特指,指代前面所说的事,但不是同一事情,即同类异物。可指代不可数名词或单数可数名词;that 还可以指代前面整个句子所说的内容。one表示泛指,代替单数可数名词,ones为其复数形式;the one 替代前面的单数名词 ,表示泛指,其后往往带定语,the ones 为其复数形式。有时,one 替代前面的名词,是前边名词的同位语,前边名词若是特指,则用the one。如:
  1. [福建卷改编] We have various summer camps for your holidays. You can choose one based on your own interests.
