1.一般用法：

He is a student, isn't he?

He isn't a student, is he?

(1) “have to, had better, used to”要用下列方式反问：

He has to finish the work, doesn't he?

They used to smoke, didn't / usedn't they?

You'd better get up immediately, hadn't you?

(2) “has, have”作为助动词和实意动词，反问形式不同。

We have done all the work, haven't we?

You have some time, don't you?

金牌要点如下:

2.“seldom, barely, hardly, scarcely, few, little” 语意本身是否定，因此反意问句应为肯定形式。

She seldom comes to visit us, does she?

He hardly knew it, did he?

3.当主句为祈使句，反意问句提出要求，命令应用 “will you”

Do it at once, will you?

但如表示邀请，劝告，反意问句用 “won't you”

Have a cup of tea, won't you?

4.否定祈使句应用 “will you” 来反问。

Don't open the window, will you?

5. “Let's” 短语

● 当其为肯定形式，“shall we” 提出反问

Let's play basketball, shall we?新概念英语听力

● 当其为否定形式，“all right, ok” 提出反问

Let's not go to the party, all right?

● 如为 “let us ...” 其反问形式应为 “will you” 提出请求

Let us go home, will you?

6.当 “think, suppose, consider, believe” etc被用作为主句谓语动词，其后带有宾语从句时，反意疑问问句应与从句保持一致。

I don't think that he is an honest man, is he?
