(1)在肯定的祈使句后可加上will you?would you?won’t you? can you?could you， can’t you?等，从而使语气更加委婉。

　　Come in and sit down, won’t you?

　　Be sure to come on time, can you?

　　Make less noise, will you?

　　在肯定的祈使句后，以上各种形式皆可选择,但在否定的祈使句后只能用will you?

　　Don’t be careless, will you?

　　(2) 在Let us/me祈使句后加will you?或won’t you? 在Let’s祈使句后加shall we? 或shan’t we? 从而使语气变得更加缓和.

　　Let me do it, will you?

　　Let us do it for you, will you?

　　Let’s have a rest, shall we?

　　4.陈述句部分如果含有否定意义的词时(如：never, seldom, hardly, few, little, no one, nobody, nothing, neither, none等),疑问部分必须用肯定式.

　　You have never been to Beijing, have you?

　　No one will believe you, will they/he?

　　在含有dislike, unimportant等以否定前缀构成的词的反意疑问句中,这些词仍按肯定词对待.

　　This is an unimportant question, isn’t it?

　　5.There be和That/this be 结构中的反意疑问句，陈述部分是there be 结构时，疑问部分用be there结构;是That/This be 结构时，疑问句部分用it 代替that或this。

　　There are some students playing， aren’t there?

　　That’s a good idea, isn’t it?

　　6. 不定代词作主语时的反意疑问句: 陈述句部分如果有everything, nothing等表示事物的词作主语时, 疑问部分的主语用it, 陈述部分若有everyone, someone, anyone, no one 等不定代词作主语时,其疑问句部分的主语既可用he, 也可用they.

　　Nothing has been said at the meeting, has it?

　　Everything goes well, doesn’t it?
