问题描述
定语从句章节给出了如下两例句：
All (that) he said is true.
Everything (that) he said is true.
原来平时常见的这两句话都是省略过 that 的。那么随便造个句子：
What you've done is wrong.
这句话 what 后面应该没有省略that了吧，但是感觉和上面两个例句结构是一样的呢？区别是在哪里呢？感觉问得不很清楚，但觉得三句话结构是相同的）
老师答疑
曾老师：
前两句分别是All和Everything作主语且被定语从句(that) he said所修饰。
第三句What you've done“你做的事”是名词性从句作主语（主语从句）。
但What you've done is wrong.可以改为：
The thing (that) you've done is wrong.
陈老师：
定语从句章节给出了如下两例句：
All (that) he said is true.
Everything (that) he said is true.
原来平时常见的这两句话都是省略过 that 的。那么随便造个句子：
What you've done is wrong.(what已经具有先行词+关系代词的语法功能,因此what前面不可以再有先行词.)
=The thing that you have done is wrong.
这句话 what 后面应该没有省略that了吧，但是感觉和上面两个例句结构是一样的呢？区别是在哪里呢？感觉问得不很清楚，但觉得三句话结构是相同的）
以上句子结构核心关键为：先行词+关系代词that/who=具有双重身份/含义连词what
(1)all that引导定语从句=what引导主语从句并在主句充当某一语法成分。
All that should be said has been said.（that作主语，不可以省略）
=What should be said has been said. （what should be said作主句的主语成分，what同时又作从句的主语成分）
(2)all that+谓语+其它，如果关系代词在定语从句作宾语成分，可以省略，不写出来,关系代词that在定语从句作主语，不可以省略，必须写出来。
All （that） he said is useless.
=All he said is useless.
=What he said is useless.
