1.当陈述部分的主语是one时，其简短问句部分在正式场合用one，在非正式场合用you。例如：
One should do one's best for the work, shouldn't you（one）?
One must do one's duty, needn't one（you）?
注意本句中must有"应该；必要"的意思，因此简短问句部分要用needn't。如果must的意思是"必须"，简短问句部分要用mustn't。例如：
One must obey the rules, mustn't one（you）?
上述例句中，简短问句部分中的one泛指"人们"。
2.陈述部分是I'm..., 简短问句部分助动词用aren't。例如：
I'm twelve, aren't I?
3.当陈述部分是there be句型时，简短问句部分也要用there。例如：
There is some water in the cup, isn't there?
4.在以let's开头的祈使句中，其简短问句部分要用shall we?若以let us开头，简短问句部分要用will you? 例如：
Let's have a break, shall we?
Let us stop here, will you?
在上述两个例句中，let's的含义是包括听话的人在内，let us的含义是"请求允许"，不包括听话的人在内。
5.当陈述部分的主语是everybody, everyone，someone, anyone, no one, nobody, somebody等不定代词时，简短问句部分的主语可用he，也可用they。例如：
Everyone knows his own language, doesn't he?
Everybody enjoyed the film, didn't they?
6.陈述部分若有never，few，little，nothing，no等否定词或半否定词时，简短问句部分助动词要用肯定形式。例如：
She never goes to the cinema, does she?
Few people can live to 150 years old, can they?
7.当陈述部分是一个含有从句的主从复合句时，简短问句部分要看主句，其主语及动词都要与主句保持一致。例如：
He says she is a good teacher, doesn't he?
They said he had left, didn't they?
但当主句是I suppose, I think, I believe等结构时，简短问句部分要看从句。例如：
I think she is all right now, isn't she?
I don't believe he is here, is he?
8.当陈述部分是祈使句的否定形式，简短问句部分用will you? 例如：
Don't play in the street, will you?
