附加疑问句

附加疑问句（Tag Question）
附加疑问句有以下四种形式：
①肯定陈述句+否定的附加疑问句That clock is slow, isn’t it?
②否定的陈述句+肯定的疑问句That clock isn’t slow, is it?
③肯定陈述句+肯定的疑问句That clock is slow, is it?
④否定的陈述句+否定的附加疑问句That clock isn’t slow, isn’t it? 前两种是主要的，后两种形式仅在特定的语境中表示感情色彩。

附加疑问句也可以由“祈使句 + 附加问句”构成
e.g. Carry this parcel for me, will you?
Remember to buy some meat, won’t you?
a)当陈述句部分的主语是everybody, everyone, someone, no one, nobody, somebody等指人的合成词时，附加问句部分的主语在正式语体中通常用he。

e.g. Everybody knows what he has to do, doesn’t he?
Nobody wants to go there, does he?None of the boys can do it, can he?
在非正式语体中则往往用they。

e.g. Nobody phoned while I was out, did they?
Everyone enjoyed the party, didn’t they?
Somebody borrowed my pen yesterday, didn’t they?
但若陈述部分的主语是everything, anything, something, nothing等指物的合成词时，附加问句部分的主语只能用it。

e.g. Nothing could make me give it up, could it?
Everything is ready, isn’t it?
b)当陈述部分是there-存在句时，附加问句部分主语也用~there？
e.g.There’s no help for it, is there?There’s something wrong, isn’t t here?
c) 陈述部分带有seldom, hardly, never, rarely, few, little, nowhere, nothing等否定词或半否定词时，附加问句部分用动词肯定形式。

e.g. Bob hardly got drunk, did he?There is little time, is there?
She never goes to the cinema, does she?
如果陈述部分的否定词仅带有否定前缀，那么，该陈述部分当肯定句处理，附加问句部分一般仍用否定形式。

e.g. He was unhappy, wasn’t he
d)如果陈述部分是I’m…结构，附加问句部分一般用aren’t I.
e.g. I’m late, aren’t I.
e)如果陈述部分以不定代词one作主语，附加问句部分的主语在正式场合用one, 在非正式场合用you。

e.g. One can’t be too careful, can one?/can you?
f)当陈述部分是一个带有that-分句做宾语的主从结构时，附加问句部分一般应与主句的主语和谓语保持对应关系。

e.g. You think (that) you are funny, don’t you?
He thinks (that) he is going to become a doctor, doesn’t he?
She says (that) I did it, doesn’t she?
但是，当陈述部分的主句是I suppose, I think, I believe, I suspect, I imagine等结构时，附加问句部分则往往是that-分句中主语和谓语动
词保持对应关系，但要注意否定的转移。

e.g. I think (that) he’s afraid of me, isn’t he?
I don’t think (that) she cares, does she?
g)陈述部分带有情态助动词used to 时，附加问句部分可用used to 形式或did 形式。

e.g. The Allens used to live in the country, usedn’t they?
He used to smoke fifty cigarettes a day, didn’t he?
h)陈述部分带有情态助动词needn’t 时，附加问句部分通常仍用need。

e.g. You needn’t go yet, need you? 在这里也可用must，作必要讲i)陈述部分带有情态助动词must 表示义务时，附加问句部分通常仍用must。

e.g. You must work hard next term, mustn’t you?
You mustn’t walk on the gras s, must you?
但当must作“有必要”解释时，随后的附加问句部分既可用mustn’t，也可用needn’t。

e.g. You must go home right now, mustn’t you/needn’t you?
而常用的肯定的形式我们用must~？否定形式用needn’t ~？
当must表示“一定，想必”等推测性意义时，附加问句部分仍用must。

e.g. He must be very tired, mustn’t he?
在这种语境中，间或也可根据上下问采用其他的动词。

e.g. He must be very tired, isn’t he?
He must have waited here for a long time, hasn’t he?
You must have seen the play last week, didn’t you?
j)在由“祈使句+ 附加问句”构成的附加问句中，附加问句部分一般用will you, won’t you, would you.
e.g. Don’t move the chair, will you? Be quiet, would you?
有时也可用can you, can’t you, why don’t you, could you等。

e.g. Give me some cigarettes, can you?Be quiet, can’t you?
但是在以Let’s开首的祈使句后，附加问句部分用shall we？
e.g. Let’s go fishing, shall we?Let’s stop here, shall we?
以Let us开首的祈使句，如果含义是allow us, 不包括听话人在内时，附加问句部分用will you，也就是当一般的祈使句处理。

e.g. Let us go now, will you?
Let us have a look at your photo, will you?
k)另外请注意陈述部分有have（has, had）的情况.
e.g. You often have headaches, don’t you?
She had a good time, didn’t she?
Tom has to walk to school, doesn’t he?
He has already had his breakfast, hasn’t he?
You’d better turn off the computer, hadn’t you?
