英语定语从句关联词什么时候作主语或作宾语 英语定语从句关联词什么时候作主语或宾语

当它在该定语从句中充当主语成分时，就是主语。如：
I have a book which is about animals. 该句中的which是修饰book的，你把它换成book后放到从句中，就变成了the book is about animals.这样你就可以判断出它就是从句的主语。
宾语也是一样。如：
This is the gift which my father gave to me. which修饰gift，= my father gave the gift to me. 所以which是gave的宾语。
