7.当陈述部分带有表示“所有”含义的动词 have 时,附加疑问部分既可以用have形式,也可用do 形式;如果陈述部分的动词是have的否定形式,附加疑问部分是用have形式还是用do形式,取决于陈述部分的动词形式。 例如:You have a Rolls-Royce, haven't you/don't you?
He hasn't a lot of time to spare, has he?
Miss Smith doesn't have any money in her pocket, does she?
当陈述部分的have不表示“所有”而表示其他含义时,附加疑问部分则用do形式。 例如:You often have headaches, don't you?
She had a good time yesterday, didn't she?
8.陈述部分带有情态动词 ought to时,附加疑问部分在英国英语中仍用ought to形式,但在美国英语中常用should形式。 例如:The child ought to be punished, oughtn't he?
We ought to go there, shouldn't we?
9.陈述部分带有情态动词used to时,附加疑问部分可用used to形式或did形式。 例如:The Greens used to live in the country, usedn't they?
He used to smoke fifty cigarettes a day, didn't he?
10.陈述部分带有情态动词needn't时,附加疑问部分常用need,但有时也可用must。 例如:You needn't go yet, need you?
He needn't do that, must he?
11.陈述部分带有情态动词must表示“必须”时,附加疑问部分用mustn't。 例如:You must work hard next term, mustn't you?
当陈述部分的must表示“有必要”时,附加疑问部分则用needn't。 例如:You must go home right now, needn't you?
当mustn't表示“禁止”时,附加疑问部分一般用must。 例如:You mustn't walk on grass, must you?
当陈述部分的must 表示“一定”、“想必”等推测意义时,附加疑问部分不用must,而要根据陈述部分的不定式结构采用相应的主动词或助动词形式。 例如:He must be very tired, isn't he? (He must be very tired = I'm sure he is very tired.)
He must have waited here for a long time, hasn't he? (He must have waited…= I'm sure he has waited …)
You must have seen the play last week, didn't you? (You must have seen…= I am sure you saw…)
12.在由“祈使句+附加疑问”构成的附加疑问问句中,附加疑问部分一般用will you, won't you, would you, 有时也可用can you, can't you, why don't you, could you 等。 例如:Don't move the chair, will you?
Be quiet, would you?
Give me some cigarettes, can you?
Be quiet, can't you?
但是,以let's 开首的祈使句,附加疑问部分用shall we。 例如:Let's go camping, 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,附加疑问部分则用will you。 例如:Let us go now, will you?
Let us have a look at your book, will you?
13.当陈述部分是并列句,疑问部分通常与最临近的分句保持一致。 例如:He is a teacher,but his wife is an engineer,isn't she?
