附加疑问句特例:

3.当陈述部分的主语是不定代词everything, nothing, anything, something时,附加疑问句中的主语一般用it,不用they。如: Everything seems all right now, doesn't it?
4.当陈述部分的主语是指示代词this, that或these, those时,附加疑问句中的主语分别用it和they。如: This is important, isn't it?
5.如果陈述部分是以代词one作主语,附加疑问句中的主语在正式场合用one,非正式场合用you,在美国英语中,在非正式场合还可以用he。如: One can't be too careful, can one?或can you?
6.如果陈述部分用I'm…结构,附加疑问部分一般用aren't I。如:I am strong and healthy aren't I。

10.当陈述部分为主从复合句时,附加疑问部分一般应与主句的主语和谓语动词保持对应关系。如: She says that I did it, doesn't she? 但当陈述部分的主语是I,谓语是think, believe, suppose, expect这类动词时,附加疑问部分则往往与从句中的主语和谓语动词保持对应关系,但要注意否定的转移。如: I don't think she cares, does she?
11.当陈述部分是并列句,附加疑问句则需和就近的分句的主语和谓语一致。如: Xiao Lin has been writing letters all afternoon but he should finish them now, shouldn't he?
12.在由“祈使句+附加疑问”构成的附加疑问句中,附加疑问部分一般用will you, won't you, would you,有时也可用can you, can't you, why don't you, could you等。如: Don't open the door, will you? Give me some bread, can you? 但是,以let's开头的祈使句,附加疑问部分用shall we;以let us开头的祈使句,如果含义是让我们us,不包括听话人在内,疑问部分用will you。如: Let's have a basketball match this afternoon, shall we? Let us go out for a rest, will you?
13.当陈述部分带有情态动词must表示“必须”时,疑问部分用mustn't。如: I must answer the letter, mustn't I? 但若表推测这层含义时,不能用must,而要根据陈述部分的不定式结构(即must之后的动词)以及含义采用相应的动词形式。如: You must have made a mistake, haven't you?
