怎样改写反意疑问句？
1)陈述部分的主语是I，疑问部分要用isn't I.或aren't I.
I'm as tall as your sister，aren't I?
（我和你姐姐一样高，对吗？）
2)陈述部分的谓语是wish，疑问部分要用may +主语。
I wish to have a word with you, may I?
（我希望可以和你说话，可以吗？）
3)陈述部分用 no, nothing, nobody, never, few, seldom, hardly, rarely, little等否定含义的词时，疑问部分用肯定含义。
The Swede made no answer, did he / she?
Some plants never blown (开花), do they ?
4)含有ought to 的反意疑问句，陈述部分是肯定的，疑问部分用shouldn't / oughtn't +主语。正式文体用should/ought +主语+not形式。
He ought to know what to do, oughtn't he? / shouldn't he?
5)陈述部分有have to +v. (had to + v.)，疑问部分常用don't +主语（didn't +主语）。
We have to get there at eight tomorrow, don't we?
6)陈述部分的谓语是used to 时，疑问部分用didn't +主语或 usedn't +主语。
He used to take pictures there, didn't he? / usedn't he?
7)陈述部分有had better + v. 疑问句部分用hadn't you?
You'd better read it by yourself, hadn't you?
8)陈述部分有would rather +v.，疑问部分多用 wouldn't +主语。
He would rather read it ten times than recite it, wouldn't he?
