5. 关系代词what引导

She has got what she wanted. 她要的东西得到了。

He could not express what he felt. 他无法表达内心的感受。

They did what they could to console her. 他们尽量安慰她。

They thought they could do what they liked with him. 他们以为他们可以对他为所欲为。

【注意】有时介词后可接一个宾语从句(但介词后通常不接that和if引导的宾语从句)：

From what you say, he is right. 根据你所说的，他是对的。

有极个别介词(如but, except)可接that引导的宾语从句：

She remembered nothing about him except that his hair was black. 她对他什么都不记得，只记得他的头发是黑的。

比较下面两句用what引导的宾语从句，它们的意思不一样：

He began to think about what he should do. 他开始考虑应当怎样做。
