介词+名词性从句

介词后面也能接名词性从句。从字面上来看，名词性从句也就是一个句子整体上做介词后面的名词成分。所以，只要我们能够抓住名词性从句的特征，就能一眼识别出来，从而迅速将复杂的句子变得简单。

我们要知道，引导名词性从句的引导词通常有what， who，why，where，how，when，if，whether等。其中， what、who和why后面只要接动词就可以成为名词性从句，而其他的引导词必须要加上主语和动词才能构成名词性从句。

There are differences in what you and Lily saw.

“in what you and Lily saw”就是介词+ 名词性从句的结构，因此，可以将它删去。这个句子就变成了There are differences.

现在让我们做一下练习吧！

2.I have a question about how you dealt with it.

3.I want to know about what he said to persuade her.
