2015年职称英语考试语法：反义疑问句的用法
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?
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?
● 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。
Idon't think that he is an honest man,is he?
