反意疑问句简介
反意疑问句相当于“对不对？”“好不好？”“行不行？”，用yes或 no 回答。由两部分组成，前一部分是陈述句，后一部分是附加疑问短语，中间用逗号隔开，所以反意疑问句又叫附加疑问句。通常的形式是：肯定的陈述句＋否定的附加疑问，或否定的陈述句＋肯定的附加疑问。
如：He studies English, doesn’t he?
He doesn’t study English, does he?
They are from America, aren’t they?
They are not from America, are they?
一、陈述句如果是there be句型，则附加疑问句要用there充当主语，而不用it或者they来与存在句中的主语保持一致：
1. There is a cup on the table, isn’t there?
2. There were lots of people over there, weren’t there?
3. There’s nothing wrong, is there?
二、陈述句的主语如果是everyone (everybody)，someone (somebody)，anyone (anybody)，no one，nobody，则在附加疑问句中通常使用they，尤其是在口语中。但是，使用he也是正确的：
1. Somebody borrowed my pen yesterday, didn’t they?
2. No one was injured in the car accident, were they?
3. Someone died here yesterday, didn’t they?
但在正式语体中也可以见到用he的实例：
Everyone knows his name, doesn’t he?
三、陈述句的主语如果是this，that，these，those，则附加疑问句中的主语要分别用it或they：
1. That is your hat, isn’t it?
2. Those are ugly, aren’t they?
四、附加疑问句通常要重复复合句中主句的主语，但主句中如果含有I think /suppose / expect /believe /imagine /fancy /suspect这样的主谓结构，则附加疑问句应重复that从句中的主语：
1. I suppose you are not serious, are you?
2. I expect you will have a good time there, won’t you?
3. I don’t believe he has finished, has he?
五、否定转移句的附加疑问句，其主语应重复that从句的主语：
1. I don’t think you can do these exercises alone, can you?
2. I don’t imagine he cares, does he?
3. I don’t think she knows French, does she?
六、在Let’s与Let us (me)句后的附加疑问句的主语是不同的：
1. Let’s go for a walk, shall we?
2. Let us go shopping, will you?
3. Now, let me have a look at that project, will you?
七、陈述句的主语如果是one，则附加疑问句的主语应当用one(英国英语)或he(美国英语):One can’t be too careful, can one?/ can he?
