一、定语从句的分类

有关英语定语从句讲解

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。

二、关系代词的用法

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)

h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)

,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:

He was the first person that passed the exam.他是第一个通过考试的人。

b.被修饰的先行词为all,any,much,many,everything,anything,none,the one等不定代词时,只能用that,而不用which.例如:

c.先行词被the only,the very,the same,the last,little,few等词修饰时,只能用that,而不用which.例如:

d.先行词里同时含有人或物时,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:

Who is the girl that is crying?正在哭泣的那个女孩是谁?

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:

b.关系代词前有介词时,一般用which,而不用that.例如:

This is the room in which he lives.这是他居住的房间。

c.引导非限制性定语从句,用which,而不用that.例如:

三、关系副词的用法
