18.1 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它们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)
