注意:
A). 否定式祈使句后面的附加部分不可用 won't you,
一般用 will you , 也可用can you .
e.g. Don't make a noise, will /can you?
B). Let's...., shall/ shan't we? Let's... 含义是 咱们... 包括说话的对方, 所以人称代词要用 we.
e.g. Let's go home, shall we? Let's go home, shan't we?
但 Let us/ me/him ...., will/ won't you ?
Let me ....除了可用 will you 外还可用 may I,要注意意义
Let me help you, may I? 我可以....吗?
Let me help you, will you? 你让我....吗?
