它也是个 mini-question,例如一些 have you? 或 wasn't it? 等等。我们通常用它来要求某人的确定或确认 (to ask for confirmation)。
因此,那些助动词 (auxiliary verb) 都扮演着重要的角色。
请看以下的解释。。。
我们通常在正面的句子 (positive sentence) 后用否定的疑问句尾 (negative question tag)。
1) Susan will be here soon, won't she?
2) There was a lot of traffic, wasn't there?
3) Alan should pass the exam, shouldn't he?
当然,我们也能在否定的句子 (negative sentence) 后用正面的疑问句尾 (positive question tag)。
1) Susan won't be late, will she?
2) They don't like us, do they?
3) You haven't got a car, have you?
想你留意的是。。。
You are not going out today, are you?
如果你答 Yes,就代表 Yes, I am going out.
如果你答 No,就代表 No, I am not going out.
