Its hard work, but I enjoy it. “Where is the dog?” “Its in the bedroom. ” 2. 指人 it 指人主要用于指不性别不明的婴儿或用于确认某人的身份。如： Is it a boy or a girl?

2、 There is a knock on the door. It must be the postman. 【说明】在答语中，常用来指本人，如说 Its me。3. 代替某些代词 代词 it 还可用于代替指示代词this, that 以及复合不定代词 something, anything, nothing等。如： “Whats this?” “Its a new machine. ” Nothing is wrong, is it? 二、it 作非人称代词的用法1. 基本用法 ： 主要用于指时间、距离、价值、天气、气候及温度等自然现象。如： Its too late to go there
