反意疑问句
反意疑问句相当于“对不对?”“好不好?”“行不行?”,用yes或 no 回答。由两部分组成,前一部分是陈述句,后一部分是附加疑问短语,中间用逗号隔开,所以反意疑问句又叫附加疑问句。通常的形式是:肯定的陈述句+否定的附加疑问,或否定的陈述句+肯定的附加疑问。
如:
He studies English, doesn’t he?
He doesn’t study English, does he?
They are from America, aren’t they?
They are not from America, are they?
反意疑问句的主要形式:
(如can, shall, will 等),其反意疑问句用同一助动词。
如:
We are late, aren’t we?
You haven’t met my wife, have you?
He can drive a car, can’t he?
They used to have difficulty in just making ends meet, didn’t (usedn’t) they?
You’d better eat with knives and forks, hadn’t you?
, hardly, never, rarely, few, little等否定词或半否定词时,因为主句本身具有否定意义,附加疑问部分的动词用肯定式,
如:
We seldom go to the cinema, do we?
Sue almost never worked, did she?
“I am…”结构,由于”am not”没有相应的缩略形式,附加疑问部分一般用aren’t I 代替。
如:
I am your friend, aren’t I?
I’m late, aren’t I?
I am a student, aren’t I?
在祈使句中的附加疑问部分一般用will you, won’t you.
4. 在祈使句中的附加疑问部分一般用will you, won’t you.
如:
Sit down, will you?
Have some tea, won’t you?
Open the window, won’t you?
这种句子可以理解为: Will you do something?
注意:否定的祈使句之后,只能用will.
如:
Don’t forget, will you?
Don’t make so much noise, will you?
