This is the dictionary which helps me a lot. 2 意义不同 一般情况下，限制性定语从句是用来限制先行词的意思，与先行词关系紧密，如果去掉的话会使句子意思不明确；而非限制性定语从句与先行词关系松散，常对先行词起附加说明的作用，即使去掉也不影响句子的主要意思。 3引导词不完全相同 非限制性定语从句有两个禁忌：that和why不能引导非限制性定语从句。在非限制性定语从句中，that的作用由who，whom和which分别承担。 Yesterday I met jenny, who was very tired. 引导词的省略情况不同 在限制性定语从句中，关系代词充当宾语时可以省略。 I lost the photos (that/which)
