17． 当陈述部分的主语有缩写形式 'd时，要分清是would， could， should还是had的缩写形式；若有缩写形式 's时，要分清是is 还是has 的缩写。这也是各种考试中经常出现的热门考点之一。例如：

You'd like to go with her， wouldn't you？　(You'd=you would)

　　 He'd rather die than give in， wouldn't he？　(He'd=he would)

　　 　Mary's coming tomorrow， isn't she？　(Mary's=Mary is)

　　 　Peter's heard the news， hasn't she？　(Peter's=Peter has)

　　 She's used to living in the country， isn't she (She's=She is)

16． 若陈述部分含有由连词"but，and，or，for"等构成的并列句时，则反意疑问句的疑问部分要根据第二个分句的主谓语来决定。例如：He failed many times， but he succeeded at last， didn't he？

　　 He is a doctor，but his wife is a teacher， isn't she？

　　 I speak Chinese，but he speaks English， doesn't he？

　　 We must hurry，or we will be late for class， won't we？

　　 She studies hard，for it is the third time that she has been praised，isn't it？

15． 当陈述部分有"It is said(told， reported， believed等)+that clause"时，其反意疑问句的疑问部分要与从句中的主谓语保持一致。例如：

It is reported that the police caught the thief yesterday， didn't they？

　　 It is said that she has won the first place in this competition， hasn't she？

14． 若陈述部分是被动语态形式且带有动词定式做主语补足语时，其疑问部分中动词形式必须根据句意用不同的时态，分述如下：

①　若有表过去的时间状语或者谓语动词是过去是时态，疑问部分助动词did构成。例如：

He is said to have finished the research work last year， didn't he？

②若谓语是一般现在时或主语补足语含有be动词时，则疑问部分用be的适当形式。例如：

She is said to be running a big company， isn't she？

③若谓语是一般现在时且主语补足语是完成式时，则疑问部分用have的适当形式。例如：

They are said to have read that book， haven't they？

13． 当陈述部分是由"I'm sure that； I'm afraid that； We are sure that； We are afraid that； I feel sure that； I hope that； We feel sure that； It seems that"等句型构成时，因主要意思在从句，故疑问部分的主语要与从句的主语保持一致。例如：

I'm sure that you know him well，don't you？你肯定非常了解他，是吧？

It seems that you are an expert，aren't you？你好像是个专家，对吧？

12．can't 表示推测，作“不可能”解时, 附加部分根据后的动词选用相应的形式。

　　 He can't be a doctor, is he?他不可能是个医生，对吧？

The students can't have finished their work, have they? 学生不可能已经做完了作业，对不对？

11．感叹句的反意疑问句中，附加部分用 be 的一般现在时的否定式，主语则在逻辑上与感叹句保持一致。如：

What fine weather, isn't it? 多好的天气，是吧？

How hard she works, isn't she? 她学习真努力，是不是？

10．含情态动词dare或need的反意疑问句，疑问部分对应的用need 或dare。如：

We need not do it again, need we? 我们不必再做了，是吧？

You dare not say so, dare you? 你不敢说，是吗？

但是，当dare, need 为实义动词时，疑问部分用助动词do/does/did。

She doesn't dare to go home alone, does she?

9．含有ought to 的反意疑问句，陈述部分是肯定的，疑问部分用“shouldn't / oughtn't +主语”。例如：

He ought to know what to do, oughtn't / shouldn't he? 他应该知道怎么办，是不是？

8．陈述部分用used to (过去常常)时，疑问部分用did或used均可。例如：

He used to live in the country, didn’t he?/usedn’t he? 他曾经住在乡下，对吧？

注：当"used to…"后有联系动词"be"时，疑问部分既可用"usedn't，也可用wasn't/weren't. 例如：

They used to be good friends, didn’t they?/usedn’t they? 他们曾是好朋友，是吗？

There used to be a river there，usedn't/wasn't there？那儿曾经有条河，对不对？
