今天来点专四题12

我把前面一大堆统一叫做疑问词，是因为在不确定用什么的时候，通常要把前面的句子先拿来变成疑问句，看是用什么提问，用什么提问后面就写什么。

e.g. They didn't go, did they?

(先把前面部分变成疑问句：Didn't they go？用didn't提问，跟据前肯后否前否后肯的原则，后面用did，主语是they)

one

one做主语，后面用 he，one

不定代词

表示事物：everything, anything, nothing等用 it

表示人：everyone, no one, nobody等用 they

[注] ：以前初中Vivian学的是用he，但是大学上语法课老师说的是现代英语更多用they。最重要的是：

这是2016年专四真题，答案就是D

There be

There be开头的句子，反义疑问句用xxx there ?

不定式和ing

to do和doing作主语的时候，反义疑问句的主语部分要用 it

e.g. Seeing is believing, isn't it?

复合句

这就是最具迷惑性的I believe, I suppose, I think, I expect, I guess等结构。

一般都不看这些部分，要在后面的从句中寻找真正的主语和疑问词。

e.g. I believe that she will come back one day, won't she ?

[注] ：若出现转移否定了，后面半句就要用肯定。

e.g. I don't believe that she will come back one day, will she ?

[注] ：如果前面部分是二、三人称，反义疑问句的主语就是它们了。

e.g. She believed that he can come back one day, didn't she?

She doesn't believe that he can come back one day, does she ?

Let's/let us/let me

遇到let's用shall we

遇到let me用will me

遇到let us，一般是对第三个人说，我们俩要干个啥，比如你放假回家爹妈说:"Let us know the time of your arrival, will you?"
