语法精讲
定语从句是用来充当句中定语的句子,它主要用于修饰名词和代词,其位置位于被修饰的名词和代词之后。在被修饰的词与定语从句之间往往有一个关系词将其前后两部分联系成一个整体。关系词可分为两种:关系代词和关系副词。常见的关系代词有:that,which,who,whom,whose。
一、who,whom和whose
1.who
用于指人,在定语从句中作主语、表语或宾语,作宾语时可以省略。
Visitors that/who come from different places are deeply attracted by the scenery there.
来自不同地方的参观者被那里的景色深深吸引。
The person who tries to do something but fails is a lot better off than the person who tries to do nothing and succeeds.
努力过却失败的人比那些坐享其成的人要好得多。
2.whom
用于指人,在定语从句中作宾语,可用who代替;但是,若从句中的介词提到关系代词前,只能用whom直接跟在介词后作宾语,不可用who代替。
Actually,he is an honest and reliable person (who/whom) you can depend on.
事实上,他是一个诚实可靠的人,你可以信赖他。
As far as I’m concerned,a man’s character can be measured by the types of his friends with whom he stays.
就我而言,一个人的性格可以通过与之相处的朋友的类型来衡量。
3.whose
表示所属关系,既可指人又可指物,在定语从句中作定语。指物时相当于of which;指人时相当于of whom。
Our daughter Georgia did decide to donate a large bag of toys to a little girl whose mother was unable to pay for her holiday due to illness.
我们的女儿乔治娅确实决定捐赠一大袋玩具给一个小女孩,她的母亲因为生病无法支付假期的费用。
