It的用法It的用法在高考中也是重现率较高的语言点，尤其是it用于强调句。
其考查方式多通过“单项填空”进行，偶尔也出现在“短文改错”和“完形填空”中。
一、要点点拔1．代替上文中提到过的人或事物。
指代人时，一般用于小孩或身份不十分明朗的人。
1) －Who is the baby? －It‘s my teacher’s son．2) －Who is that gentleman?－It's my friend Tom．He(不可用It) wants to see you．2．用于表达天气、环境、时间、距离、季节等。
例如：1) It’s half an hour’s walk from here to our school．2) It‘s nice and warm here．3) But it's two o'clock now, and it's time for us to go to school．3．用作形式主语.it 没有具体意义，而只是帮助把真正的主语移至句子后尾，使句子显得平稳一些，能借it 给移至句子后尾的主语有三种：一种由不定式表示，一种由动名词表示，一种由从句表示。
1).It 替代真正的主语——动词不定式短语.It is easier to say than to do .It is a good act to help the others.2).it 替代真正的主语——动名词短语,以动名词短语做主语的句子，主要在以no good, no use, no harm, dangerous, foolish 等词作表语的句中.It’s no harm drinking running water in that area。
It’s foolish talking like that.3).it 替代从句作主语，用从句做主语的带it 的句子很多,常见的有下面几类：① It is a pity (a shame ,a fact ,a wonder ,a good thing,etc. )that…It is a shame that he didn’t pass the exam.② It is strange ( surprising,obvious ,true, good,possible,clear,etc. ) that… 。
