all后接定語從句時用什么關系代詞

若all指人，則修飾它的定語從句用關系代詞who引導；若all指事物或現象，則修飾它的定語從句用關系代詞that引導。如：

All who heard the story were amazed. 聽到這個故事的人都感到吃驚。

He was a man who was beloved by all who knew him. 每一個認識他的人都敬重他。

All that glitters is not gold. 閃光的東西不都是金子。

All that matters is to be happy. 最重要的是要心情愉快。

All that remains for me to do is to say goodbye. 剩下我所要做的就是告辭了。

注：若關系代詞用作賓語，則關系代詞也可以省略。如：

All (that) he wants is more pay for less work. 他只想少干活，多拿錢。

All (that) I did was give him a little push. 我只不過稍微推了他一下。
