初中英语知识点:定语从句中只能用which
定语从句中只能用which,不能用that的几种情况: 1. 在介词后面的关系代词用which而不能用that。即“介词+which(代物)” 例如: The picture for which he paid $1,000 was once owned by a duke. 他花了1000美元买下的画曾为一名公爵所拥有。 The building in which Han Mei studied was very old. 韩梅在里边学习的那幢大楼很旧。 2. 在非限定性定语从句中不能用that。例如: Crusoe's dog, which was very old now, became ill and died. 克鲁索的狗,现在已经很老了,病死了。
