1. 英语语法
  2. 定语从句
  3. 关系代词引导的定语从句

关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。

1)who、whom、that

这些词代替的先行词是人的名词或代词,在从句中所起作用如下:

Is he the man who/that wants to see you?

他就是你想见的人吗?(who/that在从句中作主语)

He is the man whom/ that I saw yesterday.

他就是我昨天见的那个人。(whom/that在从句中作宾语)

2) Whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换)。

例如:

They rushed over to help the man whose car had broken down.

那人车坏了,大家都跑过去帮忙。

Please pass me the book whose (of which) cover is green.

请递给我那本绿皮的书。

3)which、that所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等。

例如:

A prosperity which / that had never been seen before appears in the countryside.

农村出现了前所未有的繁荣。(which / that在句中作宾语)

The package (which / that) you are carrying is about to come unwrapped.

你拿的包快散了。(which / that在句中作宾语)
