反义疑问句要遵循的原则：如若陈述部
分是用肯定形式，那么疑问部分就要用否定
形式, 如若陈述部分用的是否定形式，则疑问
部分要用到肯定形式，我们也可以说成前肯后
否或者前否后肯。
例如：Tom works hard, doesn't he？
Tom doesn't work hard, does he？
二、注意事项
(1)如果陈述部分含有never, seldom,hardly，
few, little, nothing, none等表示否定意义的词
时，后面的反意疑问句要用肯定形式。
例如：There are few students in the room,
are there?
(2)当陈述部分含有un-前缀、-less后缀等表
示否定意义的词时，例如：unhappy, dislike
等，我们要把他当做肯定句处理，疑问部分
还用否定形式。
如：Your mother looks unhappy, doesn't
she?
三、特殊情况
当主句含有think, believe, suppose, imagine,
expect等词时，要注意两种情况：
(1)主句主语如果是第一人称，疑问部分要与从
句保持一致。
例如：I think my mother will be back this
week, won't she?
但如果主句中含有否定词，则疑问句还是要
用肯定形式。也就是说反义疑问句部分看从
句，但用肯定还是否定要根据主句判断。
例如：I don't imagine that he can do it
well, can he?
(2)如果主句的主语为二三人称时，其后的
问句则应与主句相一致（即反义疑问句部
分只看主句，不看从句)。
例如：Your teacher believes she needs
no help, doesn't she?
四、做题易错解析
1. 以Let's开头的祈使句，疑问句要用shall
we; 以Let us开头的祈使句，疑问句要用will
you。
例如： Let us know the time , will you?
Let's go back, shall we?
2. There be句型
There be 句型反义疑问部分要用be there
例如：There are some flowers in the
garden, aren't there?
3.句子中含有 must的情况
当陈述部分有must时，问句有以下情况：
（1）mustn't表示“禁止，不必”时，问句通常要
用must.
例如：You mustn't stop your car here, must
you?
（2）must表示“有必要，必须”时，问句通常要
用needn't.
例如：Lucy and Lily must finish the
homework today, needn't they?
（3）当must用来表示推测含义时，问句要
根据must后面的动词采用相应的形式。
例如： Your brother must be good at
maths, isn't he?
4. 关于have的反意疑问句要注意以下几点：
(1). 当 have 是助动词时，反意疑问句要用同样
的词：
例如：My brother has already left, hasn’t he?
(2). 当 have 为实意动词表示“有”“吃”“玩”的时
候，反意疑问句要用助动词do：
例如：Lucy has a lot of books, doesn’t she?
Your father had a good time at the party, didn’t
he?
She has breakfast at 7, doesn't she？
