it是代詞，它可以用來指人和物，也可以一個句子或者一個短語等。無論是在口語及書面語中，甚至是考試中都會用到或碰到它。下面我們對它的用法進行總結。

1.it常指無生命的東西、動物、植物等，一般譯成“它；這；那”。比如：

2.it可以作無人稱動詞的主語，表示天氣、時日、距離、狀态、溫度等等。比如：

It will rain tomorrow.明天要下雨。What time is it?幾點了？It's two miles to the beach.距離海灘兩英裡遠。

3. 當it指人的時候，經常指不知道這個人的性别或者嬰兒等。比如：

Her baby's due next month. She hopes it will be a boy.她的孩子該下個月出生。她希望會是個男孩。Her baby's due next month. She hopes it will be a boy.她的孩子該下個月出生。她希望會是個男孩。
