1、由情態(tài)動(dòng)詞構(gòu)成反義疑問(wèn)句

①wish若在陳述部分作謂語(yǔ)，用“May I”反疑

②祈使句后邊的反義疑問(wèn)句，用will you,won't you,would you,can you,can't you,could you.

*won't用于邀請(qǐng)別人，其他是自己要求別人干某事

*祈使句否定結(jié)構(gòu)后邊，只能用will you?

Sit down please,won't you?

Do me a favor,can you?

③let's開(kāi)頭祈使句用shall we?(包括雙方）

let's meet him,shall we?(征求對(duì)方意見(jiàn)）

特例：Let's not invite him,ok(all right)?

④dare用作情態(tài)動(dòng)詞，反義本身用作實(shí)意，

Mary dare not go out,dare she?

⑤陳述部分用need't構(gòu)成，后邊可用need或must。

⑥ought to 用陳述部分，反義用本身 oughtn't

⑦h(yuǎn)ad better用在陳述部分，反義用hadn't

⑧would rather/sooner/like,用wouldn't

⑨used to放在陳述部分，若用作情態(tài)動(dòng)詞用usen't,用作實(shí)意動(dòng)詞用didn't

There used to be a chair,wasn't there?

⑩have to 放在陳述部分，反義用do各種形式。

She has to get there on time,doesn't she?

must用在陳述部分，反義用法比較復(fù)雜。

a、must 當(dāng)“應(yīng)當(dāng)，必須”講時(shí)，用mustn't,needn't均可。

b、當(dāng)must在陳述句中當(dāng)不準(zhǔn)意思表否定時(shí)，后用must.

c、當(dāng)must當(dāng)猜測(cè)時(shí)，還原本意在看

He must in his office,isn't he?

They must be talking,aren't they?

He must have seen the film yesterday,didn't he?

The street have been cleaned yesterday,wasn't it?
