反义疑问句
1．陈述部分肯定式+疑问部分否定式
2．陈述部分否定式+疑问部分肯定式
They work hard, don’t they?
She was ill yesterday, wasn’t she?
You didn’t go, did you?
He can’t ride a bike, can he?
请注意以下句型的反义疑问句的用法：
1.当陈述部分的主语是everybody, everyone, someone, nobody, no one, somebody等合成代词时，附加疑问句中的主语通常用they。但亦可用he，尤其是nobody, no one等作主语，具有否定概念时。如：
Somebody phoned while I was out, didn’t they?
Nobody wants to go there, does he?
2.当陈述部分的主语是指示代词this, that或these, those时，附加疑问句中的主语分别用it 和they。如：
This is important, isn’t it?
That isn’t c orrect, is it?
These are your friends Tom and Jack, aren’t they?
3．如果陈述部分用I’m…结构，附加疑问部分一般用aren’t I。如：
I am strong and healthy , aren’t I。
4．当陈述句为there be结构时，附加疑问句中的主语也用there。如：
There’s no help for it, is there?
There’s something wrong, isn’t there?
5．陈述部分带有seldom, hardly, never, rarely, few, little, nowhere, nothing等否定词时，附加疑问部分的动词用肯定形式。如：Bob rarely got drunk, did he?
Few people know him, do they? She seldom goes to the cinema, does she?
如果陈述部分的否定词带有否定前缀，当作肯定，附加疑问部分一般仍用否定形式。如：He wa s unsuccessful, wasn’t he?
Tom dislikes the book, doesn’t he?
6．当陈述部分为主从复合句时，附加疑问部分一般应与主句的主语和谓语动词保持对应关系。如：
She says that I did it, doesn’t she?
I told them not everybody could do it ,didn’t I?
但当陈述部分的主语是I，谓语是think, believe, suppose, expect这类动词时，附加疑问部分则往往与从句中的主语和谓语动词保持对应关系，但要注意否定的转移。
I suppose that he’s serious isn’t he?
I don’t think she cares, does she?
7．在由“祈使句+附加疑问”构成的附加疑问句中，附加疑问部分一般用will you, won’t you, Don’t open the door, will you?
但是，以let’s开头的祈使句，附加疑问部分用shall we;以let us开头的祈使句，如果含义是allow us，不包括听话人在内，疑问部分用will you。如：
Let’s have a basketball match this afternoon, shall we?
Let us go out for a rest, will you?
8．当陈述部分带有情态动词must表示“必须”时，疑问部分用mustn’t。如：You must work hard next term, mustn’t you?
I must answer the letter, m ustn’t I?
但若表推测这层含义时，不能用must，而要根据陈述部分的不定式结构（即must之后的动词）以及含义采用相应的动词形式。如：
You must have made a mistake, haven’t you?
They must have seen the film last week, didn’t they?
He must be in the library, isn’t he?
9．当陈述部分含有情态动词used to时，疑问部分可用usedn’t或didn’t。如：The old man used to smoke, didn’t he?或usedn’t he?
Tom used to live here, usedn’t he?或didn’t he?
10．当陈述部分含有had better时，疑问部分用had。
如：You’d better finish your homework now, hadn’t you?
11．感叹句后的附加疑问句的谓语动词需用be的现在时，且常用否定形式。如：What a clever bo y, isn’t he?
What a lovely day, isn’t it?
12．陈述句子中的主语为动词不定式短语、动名词短语或其他短语时，疑问部分的主语通常用it。如：
Learning how to repair motors takes a long time, doesn’t it?
Between six and seven will suit you, won’t it?
Where to hold the meeting has not been decided, has it?
