Ⅴ. 几个易混淆的关系代词的比较:

(A) that & which:

在定语从句中，which 和that 在指代事物时，一般可以互换使用，但并非在任何情况下都是这样，这里介绍宜用that, 而不宜用which 的情况.

(1) 先行词为不定代词，如all, much, something, everything, anything, nothing, none, the one等。如：

3. They set up a separate state of their own, where they would be free to keep Negroes as slaves.

2. Tom's father, who arrived just now, is a famous scientist.

1. He studied hard at school when he was young, which leads to his success in his later life.

比较:　 He has a sister, who is a musician.

　　　 He has a sister who is a musician.

引导非限制性定语从句的关系代词，指人时用who, whom, whose , 指物时用which , whose; 关系副词when，where, why, etc.

3. 语义上，限制性定语从句与先行词关系紧密，起限定作用，如果去掉了这个定语从句，整个句子就不完整或者会改变意思；而非限制性定语从句与先行词关系不是很紧密，对先行词起补充说明或描述的作用。

2).Beijing, which has been China's capital for more than 800 years , is rich in cultural and historic relics. 北京是中国八百年之久的古都，它有着丰富的文化和历史遗产。
