不定代词后面用that还是which

不定代词后面用that。在定语从句中，如果先行词是不定代词，或者说被不定代词所修饰的时候，如果从句中缺少成分，这个时候只能用that.

两者都可用作关系代词引导定语从句，指物时有时可互换。如：

This is the book which/that you asked for.这是你要的那本书。

引导非限制性定语从句时，通常只用which。如：Jack drove too fast,which was reckless.杰克开车开得太快，根本不考虑后果。

直接放在介词后，作宾语时，通常只用which。如：The treasure,some of which has been recovered,has been sent to the British Museum.这些宝藏已送往大英博物馆，其中有一些是失而复得的。

当先行词是下列不定代词或被much,little,none,all,few,every(thing)，any(thing)，no(thing)等修饰时，通常用that。如：He grasped at anything that might help him.任何对他可能有帮助的东西他都想抓住。

当先行词有the very,the only,the same等修饰时，通常用that。如：Those are the very words that he used.那是他的原因。

当先行词有形容词最高级或序数词(包括last,next等)等修饰时，通常用that。如：This is the most interesting story that I’ve ever read.这是我所读过的最有趣的故事。

当关系代词在定语从句中用作表语时，通常用that。如：China is not the country(that)it was.中国已不是过去的中国了。
