一、There be 句型陳述句比較特殊, 其附加疑問句的結(jié)構(gòu)為there be的倒裝，而不帶句子主語。例如：
There is something wrong with the computer, isn't there? 這臺電腦有點毛病，是不是？
There aren't any fish in the river, are there? 這條河里沒有魚, 是嗎?
二、當(dāng)陳述部分的主語是everyone,everybody, someone, nobody, no one,none, anyone, somebody等合成不定代詞時, 在非正式文體中，附加疑問句中的主語通常用he或they。例如：
Someone opened the door, didn't he/they? 有人開了門，是不是？
Nobody went to the cinema, did they? 沒人去看電影，是嗎？
三、當(dāng)陳述部分的主語是everything, nothing, something, anything等合成詞，附加疑問句中的主語用it。例如：
Nothing serious happened, did it? 什么事情也沒有發(fā)生，對嗎？
Everything is ready, isn't it? 一切準(zhǔn)備就緒了，不是嗎？
四、當(dāng)陳述部分的謂語動詞是am的肯定形式時，附加疑問句的謂語動詞用aren't，而不用am not;當(dāng)陳述部分的謂語動詞為am not時，附加疑問句的謂語仍用am。例如：
I am five years younger than you, aren't I? 我比你小五歲，不是嗎？
I am not late, am I? 我沒有遲到，對嗎？
五、當(dāng)陳述部分帶有few, little, hardly, scarcely, rarely, seldom, never, nowhere, nothing, no one, nobody等表示否定或半否定意義的詞時，附加疑問句的動詞用肯定形式。例如：
The old man can hardly read, can he? 這位老人不識字，對嗎？
Little food has been left, has it? 吃的東西幾乎沒剩下，是嗎？
He has few good friends, has he? 他幾乎沒有要好的朋友，是不是？
六、當(dāng)陳述句部分帶有否定前綴的詞時，此陳述句當(dāng)作肯定句， 其后的附加部分用否定形式。例如：
The students were impolite, weren't they? 那些學(xué)生沒有禮貌，不是嗎？
It's illegal to drive a car without a license, isn't it? 沒有駕照開車是違章的，不是嗎？
※ 含有否定含義的詞在陳述部分作動詞的賓語時，其反意疑問句用肯定結(jié)構(gòu)，也可以用否定結(jié)構(gòu)。例如：
You got nothing from him, did you? 你從他那兒什么也沒得到，是嗎？
七、如果陳述句是主從復(fù)合句而主句的謂語是動詞I(we) + think, believe, suppose, imagine, reckon, fancy等詞時，附加部分應(yīng)與從句中的謂語在時態(tài)上保持一致。例如：
I suppose you are not serious, are you? 我想你不是當(dāng)真吧，是嗎?（不可用don't I?）
We think they have finished their homework, haven't they? 我們認(rèn)為他們已經(jīng)完成了家庭作業(yè)，不是嗎？
I believe that you will enjoy the party, won't you? 我相信你會喜歡這次聚會的，不是嗎？
八、當(dāng)陳述部分是祈使句時，附加部分可以不與前面的祈使句的動詞保持一致，而是根據(jù)不同的用意選用shall, will, can 等。例如：
Don't make noise, will you? 不要吵鬧，行嗎？
Let's help each other, will you/won't you? 讓我們互相幫助，好嗎？
Let me do it for you, will you/won't you? 讓我來幫你做這件事，行嗎？
Let us have a look at your new dictionary, will you/won't you? 讓我們看一看你的新詞典，好嗎？
〔注〕Let's（包括說話者本人）開頭的祈使句，附加部分常用shall we?或shan't we? 表示征求意見。 Let us/me/him不包括聽話人在內(nèi)開頭的祈使句，附加部分則要用will you?或won't you?
九、含had better的陳述句，附加部分用助動詞had; 含would 的陳述句，附加部分動詞用would。例如：
You'd better go home now, hadn't you? 你最好現(xiàn)在回家，好不好？
You'd like to see the film, wouldn't you? 你很想看電影，是嗎？
※ 陳述部分有have to 時，其反意疑問句要用助動詞的否定形式。例如：
You have to water the vegetables every day, don't you?你每天都要澆菜，對吧？
十、8.陳述部分的主語是不定代詞one時，反意疑問句的主語可以用one，也可用you(美式英語用he)。例如：
One should be ready to help others, shouldn't one? 每個人都應(yīng)該樂于助人，是吧？
※ 當(dāng)陳述部分主語是從句、不定式(短語)、動詞-ing形式時，反意疑問句的主語應(yīng)該用it。例如：
What you need is more important, isn't it？你需要的東西更重要，是吧？
十、附加疑問句有時可用Eh? Right? Am I right? Don't you think? Isn't that so?等。例如：
She didn't pass the entrance examination, eh? 她沒有通過入學(xué)考試，呃？
They forgot to attend the lecture, am I right? 他們忘記去上那次課了，對不對？
十一、用must表推測的反意疑問句的有關(guān)用法
1）對現(xiàn)在情況的推測，問句部分用主動詞（do,be)一般現(xiàn)在時的適當(dāng)形式。若是現(xiàn)在進(jìn)行時，問句部分用現(xiàn)在進(jìn)行時的適當(dāng)形式表示。若是there be結(jié)構(gòu)，問句用isn't/aren't there。如：
1)He must be there,isn't he?
2)He must have a big family,doesn't he?
3)He must be waiting outside,isn't he?
4)There must be some students in the room,aren't there?
2）對已發(fā)生的過去情況的推測，若陳述句謂語部分有“must have done”，而且有表示過去的時間狀語，問句部分用didn't；若沒有表示過去的時間狀語，問句部分用haven't或hasn't。如：
1)They must have gone there last night,didn't they?
2)They must have arrived by now,haven't they?（根據(jù)by now來判斷）
3)They must have been to the Great Wall,haven't they?
3）若是被動，應(yīng)按被動結(jié)構(gòu)來處理。如：
1)The room must have been cleaned yesterday,wasn't it?
2)The room must have been cleaned,hasn't it?
4）若句中有表示過去完成時的時間狀語，問句部分應(yīng)用hadn't.如:
They must have learnt 5000 English words by the end of last term,hadn't they?
(本題中must表推測，如果將它去掉，還原為真實句就是They had learnt 5000 English words by the end of last term.因此，反意問句是hadn't）
