疑问句，顾名思义，就是用来表示疑问的句子，是日常交流中非常常见的句型，也是我们学习英语语法的入门级别句子之一。虽然简单，但也分为几种类型，其中反意疑问句最难掌握，小编这次就为大家带来了反意疑问句的讲解，一起来看看吧！

1.祈使句后一般加上will you或won't you构成反意疑问句，用will you 多表示“请求”，用won't you 多表示提醒对方注意。

eg. Look at the blackboard, will you/won't you?

2. Let引导的祈使句有两种情况：

1）Let's…，后的反意疑问句用shall we或shan't we。

eg. Let's go home, shall we/shan't we?

还可以用may I来表示征求对方的同意或许可。

2）Let us/me…后的反意疑问句用will you或won't you。

eg. Let me have a try, will you/won't you?

2. 感叹句后加反意疑问句时，其反意疑问句需用be的一般现在时态的否定形式。

What a lovely puppy, isn't it?

3.当陈述部分谓语动词是need, dare, used to，且这些词被用作实义动词时，其反意疑问句需用do的适当形式。

eg. He needs help, doesn't he?

4.陈述部分主、谓语是I am…时，反意疑问句用aren't I 或ain't I ,而不是am not I （可用am I not）。

I'm working at that time, ain't I?

5.陈述部分的主语是不定代词one时，反意疑问句的主语可以用one，也可用you（美式英语用he）。

eg. One should be ready to face difficults of life, shouldn't one?

6.当陈述部分含有以下这些含有否定意义的词时：few, little, seldom，hardly, never, not, no, no one, nobody, nothing, none, neither等，其反意疑问句需用肯定结构。

eg. It's hardly to say, isn't it?

7.当陈述部分含I think (believe, suppose…) that… 结构时，其反意疑问句须与从句的主、谓语保持一致，注意主句的主语必须是第一人称。例如：

eg. I don't think he will come, will he?

8.have(has)不是表示“有”的意思，并在句中做谓语时，其反意疑问句的助动词要用do, does, did。

eg. They had a meeting just now，didn't they?

9.陈述部分有have to 时，其反意疑问句要用助动词的否定形式。

eg. You have to go to school every day, don't you?

10.陈述部分是there be句型时，其反意疑问句中要用there。

eg. There was a hospital on this street, wasn't there?

11.当陈述部分含有情态动词must时，有两种情况，① 如果must 作“一定；要；必须”讲，反意疑问句须用mustn't或needn't；② 而当must作推测意义“一定是；必定”讲时，反意疑问句则需根据must后的动词原形选用相应的形式。

eg. She must work hard at literature, mustn't she?

The kid must go to bed before 10pm，isn't he?
