每天的英语学习之关系代词引导的定语从句

　　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。关联代词在定语从句中作主语时，从句谓语动词的人称跟数要跟先行词保持一致。每天的英语学习从下面知识开始：

　　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，它还可能同of which更换）, 每天的英语学习少不了例句：
They rushed over to help the man whose car had broken down.　 那人车坏了，大家都跑从前帮忙。
Please pass me the book whose (of which) cover is green.　请递给我那本绿皮的书。

3）which, that
每天的英语学习要注意：它们所取代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. 城市浮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）
