you

1.you有时泛指“任何人”。例如：

• You never can tell. （万事不可预料。）
• You never know what you can do till you try.
• You cannot lose what you never had.
• You cannot catch old birds with chaff. （有经验的人决不会上［你的］当。）

这样用法的you比one亲切，在口语和口语式的文字里比one普通。

2.祈使句里的主语you通常省去。但有时可以用you来加重语气，用了you句子仍旧是祈使句，并不成为陈述句。例如：

• You go.
• Go you.
• You be quiet.
• You mind your own business.
• You get out of the room.
• Don't you worry about that.
• Don't you come here again.
• Don't you keep on asking me questions like that.
• Never you mind how old she is.
• Never you mind.
• But I have no objection, mind you（或mark you）.
• In you go!
• Out you come!

下面几点该注意：

（1）用Don't you...和Never you...，不用You don't...和You never...。

（2）用mind you和mark you，不用you mind和you mark。

（3）In you go!和Out you come!都是非正式的句法，只用于熟人。

（4）用you往往有把“你”跟“我”或别人对比的意思。例如：I must go away for a while. You sit here till I come back. 和You stand up. Your sister is too tired to stand any more, and would like to have the seat.

下面三句都是祈使句，但只有第一句里的You是take的主语，第二句里的You和第三句里的You都是呼唤语，不是take的主语：

• You take that chair.
• You, take that chair. （有逗号）
• Take that chair, you.

3.下面两句里都用their，不用your，也有人用your，但不合理，不算正当：

• Some of you have already handed in their compositions.
• Many of you have not yet made up their minds.

4.注意下面第一句里用us，第二句里用you。

• You and I have no misunderstanding between us.
• You and he have no misunderstanding between you.

5.you all比all of you通俗。

在美国南方you all很常用，往往也用于一个人，如向一个朋友说How are you all today? 和向一个店员说Do you all keep fresh butter here? 美国北方人说这种用法不合理，可是南方人说它是合理的，他们说you all指“你和你的家属”、“你们这店（里的全部员工）”等。
