英语口语指导:关系代词的用法
三、定语从句的分类
根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去,非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。
四、关系代词的用法
1. that 既可以用于指人,也可以用于指物。在从句中作主语或宾语,作主语时不可省略,作宾语可省略。例如:
Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。(that作主语The coat (that) I put on the desk is blue. 我放在桌子上的那件外套是蓝色的。(that作宾语)
2. which用于指物,在句中作主语或宾语,作主语不可省略,作宾语可省略。例如:
The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。(作主语)
The film (which) we saw last night was wonderful. 我们昨天晚上看的那部电影很好看。(作宾语)
3. who,whom用于指人,who 用作主语,whom用作宾语。在口语中,有时可用who代替whom,也可省略。例如:
The girl who often helps me with my English is from England. 经常在英语方面帮助我的那个女孩是英国人。(作主语)
Who is the teacher (whom) Li Ming is talking to? 正在与李明谈话的老师是谁?(作宾语)
注意:(1) 当定语从句中含有介词,介词放在句末时,who,that,which可省略,但介词在关系代词前时,只能用“介词+which/whom”结构。例如:
This is the house in which we lived last year. 这是我们去年居住的房子。
Please tell me from whom you borrowed the English novel. 请告诉我你从谁那借的这本英文小说。
(2) 含有介词的固定动词词组中,介词不可前置,只能放在原来的位置上。例如:
This is the person whom you are looking for. 这就是你要找的那个人。
(3) that 作介词的宾语时,介词不能放它的前面,只能放在从句中动词的后面。例如:
The city that she lives in is very far away.她居住的城市非常远。
(4) 关系词只能用that的情况:
a. 先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时,只能用that,而不用which.例如:

e. 以who或which引导的特殊疑问句,为避免重复,只能用that.例如:

f. 主句是there be 结构,修饰主语的定语从句用that,而不用which.例如:

(5) 关系词只能用which,而不用that 的情况:
a. 先行词为that,those时,用which,而不用that. 例如:
