杨悦惟打卡第十三天

1、that与which的区别。
　　1)用that而不用 which的情况：①先行词为不定代词all, anything, nothing, …;②先行词有最高级修饰，有序数词修饰;③先行词有only, very, any等词修饰;④先行词既有人又有物时。
　　e.g. There is nothing that can prevent him from doing it. 没有什么能阻止他不干那件事。
　　The first place that they visited in Guilin was Elephant Trunk Hill. 在桂林他们所参观的第一个地方是象鼻山。
　　This is the best film that I have ever seen. 这部电影是我看过的最好的一部。
　　Mr Smith is the only foreigner that he knows. 史密斯先生是他认识的唯一的外国人。
　　

2)用which而不用 that的情况：

①引导非限制性定语从句;

②代表整个主句的意思;

③介词 + 关系代词。
　　e.g. He had failed in the maths exam, which made his father very angry. 他数学考试没有及格，这使他的父亲很生气。
　　This is the room in which my father lived last year. 这是父亲去年居住过的房子。
