只用that的情况:the only,the very,the same,no,any先行词即有人又有物,高级,不定和序数小百姓网www.xbaixing.com。
(2)只用which不用that的情况
A. 关系代词前有介词且指物时
e.g.: I’m looking for a container in which I can put all these peaches.
A zoo is a park in which many kinds of animals are kept for exhibition.
B. 先行词本身就是that时
e.g.: I don’t like that which he did.
What is that which is on the ground?
C. 引导非限定性定语从句时
非限定性定语从句的关系代词或关系副词与先行词之间常用逗号隔开www.xbaixing.com。
e.g.: Football, which is a very interesting game, is played all over the world.
Their house was washed away by the floods, which made them sad.
另:限定性定语从句即我们初中阶段所学的定语从句,定语从句和先行词之间的关系密切,不用逗号隔开,说明先行词的性质、身份、特征等,不能去掉www.xbaixing.com。
非限定性定语从句主要起补充说明的作用,往往用逗号与先行词隔开,去掉后不影响主句的意义PqS。
(3)定语从句中的主谓一致
这里指关系代词在定语从句中做主语时,定语从句中谓语动词的单复数形式要与先行词一致的问题x b a i x i n g c o m。先行词时单数时,从句的谓语动词用单数;先行词是复数时,从句的谓语动词用复数小.百.姓.网。
e.g.: The man who is playing football is my PE teacher.
I love singers who write their own music.
