1. 基本原则
在通常情况下,当陈述部分含有情态动词时,反意疑问句会重复前面同样的情态动词:
The boy can read and write, can't he? 这男孩会读写,是吗?
We shouldn't help him, should we? 我们不应该帮助他,对吗?
You couldn't lend me any money, could you? 你不会借钱给我,对吗?
2. 当陈述部分含有must时
要分两种情况:
(1) 若must表示“必须”或“有必要”,反意疑问句用 mustn't 或needn't:
You must leave at once, mustn't [needn't] you? 他必须(有必要)马上离开,是吗?
但是若陈述部分有mustn't表示禁止,反意疑问句要must:
You mustn't laugh, must you? 你不准笑,知道吗?
(2) 若must表示推测,反意疑问句不能用must,而应根据must后的动词结构采用相应的动词形式:
He must be tired, isn't he? 他一定累了,是吗?
He must have read it, hasn't [didn't] he? 他一定读过它,是吗?
He must have left yesterday, didn't he? 他昨天一定走了,是吗?
【注】当陈述部分为“must+完成式”时,反意疑问句可用have (has),也可用did。但若句中出现了过去时间状语,则通常用did。(如上例所示)
3. 当陈述部分含有 may 时
反意疑问句根据情况可用mayn't, mightn't, won't等:
I may leave now, mayn't I? 我可以走了,行吗?
He may be here next week, mightn't [won't] he? 他下星期可能来这里,是吗?
4. 当陈述部分含有needn't时
反意疑问句通常用need,有时也用must:
We needn't tell him, need [must] we? 我们不必告诉他,对吗?
5. 当陈述部分含有ought to时
反意疑问句在英国英语中用ought to,在美国英语中用should:
We ought to leave early, oughtn't [shouldn't] we? 我们应该早点动身,对不对?
