反义疑问句解析

它表示提问人的看法,没有把握,需要对方证实。反义疑问句由两部分组成：前一部分是一个陈述句，后一部分是一个简短的疑问句，结构助动词加上人称代词主格。句子中的助动词有be, will, should，must, can等，没有助动词的要借助do, does, did等。两部分的人称时态应保持一致。

1．陈述部分肯定式+疑问部分否定式可记为前肯后否

2．陈述部分否定式+疑问部分肯定式可记为前否后肯

They work hard, don’t they? She was ill yesterday, wasn’t she?

You didn’t go, did you?He can’t ride a bike, can he? He is a student, isn't he?

特殊主语

(1)当陈述部分的主语是陈述部分主语是不定代词everybody, anyone, somebody, nobody, no one等，疑问部分常用复数they，有时也用单数he。

Everyone knows the answer, don't they? (does n’t he?) Nobody knows about it, do they? (does he?)

(2) everything,anything,nothing,something时，附加疑问句中主语一般用it 不用they （3）this,that,或those,these时，附加疑问句中主语用it和they.

（1）当陈述部分有never，seldom, hardly，few，little，barely, scarcely, nothing 等否定意义的词时，后面的反意疑问句则为肯定形式：

They seldom come late, do they?

（2）当陈述部分含有否定意思的词是unhappy,dislike,unfriendly，impossible等含有否定词缀的派生词，也就是有un-前缀、im-前缀、dis-前缀、-less后缀等含有词缀而意思否定的词，当做肯定句处理，疑问部分要用否定形式。如：

He looks unhappy,doesn't he? The girl dislikes history, doesn't she? It is impossible, isn't it?

含有think, believe, suppose, imagine, expect等动词后接宾语从句构成的主从复合句在构成反意疑问句时，视情况不同有两种不同的构成方式。

(1) 当主句的主语为第一人称时，其后的简短问句用肯定或否定看主句，人称取决于从句。

I expect our English teacher will be back this weekend, won't she/he?

We suppose you have finished the project, haven't you?

(2) 当主句的主语为第二、三人称时，其后的简短问句则应与主句相一致（此时，否定只看主句，与从句无关...）。例如：

Your sister supposes she needs no help, doesn't she?

You thought they could have completed the project, didn't you?

They don't believe she's an engineer, do they?

She doesn't expect that we are coming so soon, does she?

You’d better get up early, hadn’t you?

当陈述部分是祈使句时，疑问句要根据语气来表达

She must have read the novel last week, didn't she?

You must have told her about it, haven't you?

1) 陈述部分的主语是I，疑问部分要用aren't I.
