辽宁省抚顺县高中高三英语人教版语法专项复习：it 用法

　　高考英语一轮复习语法专项---------it 用法

　　一、it作人称代词

　　用来指代前文中提到的东西。既可指代具体的东西，也可指代一种情况。请看下面的例子

　　1）I hear you bought a new bike，can you show it to me？

　　2）If I can stop her coming to you，I shall do it．

　　3）—I want to stay here for a night．

　　—Your wife won't like it

　　此时要注意与其他代词如that，one， those，this，another等的区别：

　　1．I hear you bought a new bike，I want to buy _______ ，too．此处应填one，因为这里我并不是要买你的车，而是一辆新车，one ＝a new bike。

　　2．I have bought a new bike，but I still want to buy _______ ．此处应填another。我已有了一辆，再买另一辆。another ＝another new bike。

　　3．We see him when we come to town， but _______ isn't often．此处填that或it均可。指代前面我们去城里时可以看到他这一情况。

　　4．My seat is next to _______

　　of the headmaster．此处应填that，用来代替名词seat，that＝the seat。

　　5．The bikes made this year are better than _______ made last years．此处应填those或the ones。代替前文的bikes，因其是复数概念，故用those或the ones，those ／the ones＝the bikes。
