1、非限制性定语从句
I．限制性定语从句和非限制性定语从句的5点区别
1、形式不同
限制性定语从句与先行词之间不用逗号隔开，而非限制性定语从句与先行词之间用逗号隔开.
2、意义和作用的不同
限制性定语从句是对先行词在意义上不可缺少的限定语,如果没有从句,先行词的意思就不完整或无意义或不符合逻辑. 而非限制性定语从句是先行词的补充说明或描绘的作用, 是附加说明,不起限制作用,这种从句与先行词的关系松散, 如果省去也不致影响主句的意思. a. He is the man (whom ) I want to see.
b. T hose who wish to go to the park must be at the gate by 7:50 am.
c. Mr. Zhang, who came to see me yesterday, is an old friend of my father’s.
d. Last night I saw a very good film, which was about the Long March.
3、翻译的方式和意思不同
限制性定语从句往往翻译成一句;而非限制性定语从句往往翻译成二句.
a. The boys who wanted to play f ootball were disappointed when it rained.
希望踢足球的那些男孩因为下雨而感到失望.
