wh(whm)，which，that，whse引导的定语从句
在复合句中，修饰某一名词、代词或整个主句的从句叫作定语从句。
从句修饰的名词或代词叫作先行词，连接先行词和定语从句的词叫关系词。关系词的主要作用是连接主句和从句，同时指代先行词，并在从句中充当一定的句子成分。关系词分为关系代词和关系副词两种，关系代词有that，which，wh，whm，whse等；关系副词有when，where，why。
一、关系代词的基本用法
1．wh指人，在从句中作主语或宾语，作宾语时可省略。
The man wh is talking with my father is a teacher.
正在和我父亲说话的那个人是个教师。
The girl (wh) I met yesterday was his sister.
我昨天见到的那个女孩是他的妹妹。
2．whm指人，在从句中作宾语，常可省略，不能作主语。
The by(whm)the teacher ften praises is their mnitr.
老师经常表扬的那个男孩是他们的班长。
注意：(1)关系代词whm在口语或非正式文体中常可用wh来代替。
The by(wh/whm/that)we saw yesterday was Jhn's brther.
昨天我们看到的那个男孩是约翰的哥哥。
(2)在从句中作介词的宾语且直接跟在介词后时，用whm，不用wh。
He is a man frm whm we are all ready t learn.
他是我们大家都愿意学习的人。

这是他住的房间。
2．引导非限制性定语从句时。

四、使用定语从句的注意事项
1．关系代词在定语从句中作主语时，定语从句的谓语动词要和先行词的数保持一致。“ne f＋复数名词”作先行词，谓语动词用复数形式；“the nly ne f＋复数名词”作先行词，谓语动词用单数形式。
This is ne f the bks which were written by Charles Dickens.
这是查理斯·狄更斯所写的书中的其中一本。
He is the nly ne f the bys in ur class wh has learned French.
他是我们班里唯一一个学过法语的男孩。
注意：which引导非限制性定语从句时，往往代表前面所说的整个情况。这时which被看作单数，其后的谓语动词应用单数形式。
He said he was a Frenchman，which was nt true.
他说他是一个法国人，这不是真的。
2．为避免关系词的重复，被关系代词所代替的成分不可在从句中重复出现。
This is the factry which we visited last Sunday.(visited后不可加it)
这就是我们上星期天参观过的工厂。
3．关系代词的省略。
(1)关系代词作主语时不能省略。
(2)作动词宾语的关系代词，可以省略；作介词宾语的关系代词，如果不直接位于介词后，可省略，如果直接作介词的宾语，不能省略。
(3)关系代词which在非限制性定语从句中不能省略。
