He isn't a student, is he?
(1) “have to, had better, used to”要用下列方式反問：
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”作為助動詞和實意動詞，反問形式不同。
We have done all the work, haven't we?
You have some time, don't you?
2． “seldom, barely, hardly, scarcely, few, little” 語意本身是否定，因此反意問句應(yīng)為肯定形式。
She seldom comes to visit us, does she?
He hardly knew it, did he?
3．當(dāng)主句為祈使句，反意問句提出要求，命令應(yīng)用 “will you”
Do it at once, will you?
但如表示邀請，勸告，反意問句用 “won't you”
Have a cup of tea, won't you?
4．否定祈使句應(yīng)用 “will you” 來反問。
Don't open the window, will you?
5． “Let's” 短語
● 當(dāng)其為肯定形式，“shall we” 提出反問
Let's play basketball, shall we?
● 當(dāng)其為否定形式，“all right, ok” 提出反問
Let's not go to the party, all right?
● 如為 “l(fā)et us ...” 其反問形式應(yīng)為 “will you” 提出請求
Let us go home, will you?
6．當(dāng) “think, suppose, consider, believe” etc 被用作為主句謂語動詞，其后帶有賓語從句時，反意疑問問句應(yīng)與從句保持一致。
I don't think that he is an honest man, is he?
