The computer game which/ that he is playing is his favorite. 先行词指人时， 关系代词用（who）作主语或宾语，whom (作 宾语)，whose (作定语)，that (作主语或宾语)。 如： The man who is mending the machine has been retired. This is the policeman who/ whom they were talking about yesterday. I like the girl whose mother is an actor. 注意： 下列情况下关系代词只用 that 而不用 which 或 who。 先行词是指物的不代词，如：all, little, few, much, none, anything, nothing, everything 等时。如： I didn’t understand the words all that he said. 2．先行词由最高级、序数词以及 any, very, only, all, no, just 等 所修饰。如： This is the most beautiful place that I have been to . 行词既包括人，也包括物。如： They always like to talk about the man and the things that the ... ...
