7、当主句中有who, which时，而定语从句中也要用到who或which时，为了避免who?who, which?which等重叠，定语从句要用that引导。例如：
Who is the man that is standing by the door? 站在门边的那个男人是谁？
Which of the two cows that you keep produces more milk? 你养的那两头奶牛中哪一个产奶多？
8、人或物在定语从句中表语时，用that引导定语从句，而that通常也可以省略。例如： He is no longer the man that he was.他不再是过去的他。 二、修饰物时只用which不用that的情况 1、引导非限制性定语从句时。例如：
Bamboo is hollow, which makes it light.竹子是空心的，这使得他很轻。 2、当关系词前有介词时。例如：
This is the room in which Chairman Mao once lived.这就是毛主席曾经住过的地方。 3、在一个句子中有两个定语从句，其中一个定语从句的关系代词用了that, 另一个宜用which.例如：
Let me show you the novel that I borrowed from the library which was newly open to us.我来给你看我从新开的图书馆里借来的那本小说。 4、当关系代词后面有插入语时。例如：
Here is the English grammar which, as I have told you, will help improve your English.这就是我跟你说过的会有助于你学好英语的那本英语语法书。 5、先行词为that时。例如：
The clock is that which can tell us the time.钟是报时的装置。
在定语从句中 whom who 的区别！ 言简意赅
答：定语从句中的who和whom叫做关系代词。其中who在定语从句中充当主语，whom充当宾语。但注意：who可以代替whom作宾语，但whom 不可代替who做主语。 The man who is standing there is my teacher.
The man who/whom you saw just now is my teacher. who指人，在从句中做主语
(1) The boys who are playing football are from Class One. (2) Yesterday I helped an old man who lost his way. whom指人，在定语从句中充当宾语，常可省略。
(1) Mr. Liu is the person (whom) you talked about on the bus. (2) Mr. Ling is just the boy whom I want to see.
注意：关系代词whom在口语和非正式语体中常用who代替，可省略
China has a lot of famous writers , one of _____is Ru Xun . A. who B. whom C. that D .which
答：选B, whom和who的区别在于whom作宾语而who作主语，当然通常情况下whom可用who代替，但在其前有介词时则不可，所以应选B，这里whom指代的是famo
如何区别which 和 as
答：关系代词as和which 引导的定语从句
as 和which 引导非限制性定语从句时， 其用法有相同之处，也有不同之处。具体情况是： 1. as 和which都可以在定语从句中做主语或宾语，代表前面整个句子。如： He married her, as / which was natural. 他跟她结婚了，这是很自然的事。 He is honest, as / which we can see. 他很诚实， 这一点我们看得出来。
2. as 引导的非限制性定语从句可以放在主句之前、主句之后，甚至还可以分割主句。 which 引导的非限制性定语从句只可放在主句之后。另外，as 常常有“正如、正像”的含义。如： As is known to all, China is a developing country. 众所周知，中国是发展中国家。
He is from the south, as we can know from his accent. 他是南方人，这一点我们从他的口音可以知道。
John, as you know, is a famous writer. 正如你所知， 约翰是个著名作家。
Zhang Hua has been to Paris more than ten times, which I don't believe. 张华已去过巴黎十多次了，这一点我不相信。
注意：当主句和从句之间存在着逻辑上的因果关系时，关系词往往只用which。如： Tom was late for school again and again, which made his teacher very angry. 汤姆老是迟到，这使得老师很恼火。
These tables are made of metal, which made them very heavy. 这些桌子是金属的，这使得这些桌子很重。
3.当先行词受such, the same 修饰时，关系词常用as。 如：
I’ve never heard such stories as he tells. 我从未听过象他讲的这样的故事。
He is not such a fool as he looks. 他可不象他看上去的那样傻。
This is the same dictionary as I lost last week. 这部词典跟我上星期丢失的一样。
注意：当先行词受the same 修饰时，偶尔也用 that引导定语从句，但与as引导的定语从句意思有区别。如：
She wore the same dress that she wore at Mary's wedding. 她穿着她在玛丽婚礼上穿过的同一条连衣裙。
She wore the same dress as her younger sister wore. 她穿着跟她妹妹所穿的一样的连衣裙。
William, a famous writer, likes living in a house＿＿＿the windows face to the south. A: 错误 whose B: 正确 of which C: 错误 its D: 错误 and which 答案：B
解析：of which引导定语从句，并在从句中作定语。of which the windows = whose windows。句意：William，一位著名的作家，住在一间窗户朝南的房子
whose为什么不对？ 谢谢老师
答：如果使用whose，不应当有定冠词the。
关系代词whose在从句中作定语指物时，可与of which转换。即：物+whose+名词=物+of which + the +名词=物+the+名词+of which. 例如：
The book whose cover is green is mine. =The book of which the cover is green is mine. =The book the cover of which is green is mine.
绿色封面的那本书是我的。
老师，您好！
请问定语从句先行词后什么时候用关系代词，什么时候用关系副词？ 您能多给我举些例子么？ 谢谢！
答：同学你好! 提供以下知识点，希望对你有所帮助！
定语从句是用一个句子来作定语修饰名词或代词，通常放在它所修饰的名词或代词之后，这种名词或代词叫做先行词。引导定词从句的关联词为关系代词(which , that, who, whom, whose, as)和关系副词(when ,where ,why )，关系代词在定语从句中可用作主语，宾语，定语等，关系副词在定语从句中只是用作状语。
eg：(1) The student(先行词) who answered the question(主语) was John. (2)I know the reason(先行词) why he was so angry(状语). 2、使用关系代词还是关系副词是难点
在选择关系词时，同学们的误区是：如先行词是时间就用when，如先行词是地点就用where，如是reason就用why，如此推理大错特错。最佳方法还是看关系词在定词从句中所作成分
eg：
This is the place that/which we visited last month. (关系词作宾语，因此用that或which)
I often think of the days that I spent in Browns last summer. (关系词作宾语)
This is the place where he works.
(关系词作状语＝in the place，因此用where)
老师麻烦你把定于从句给我总结一下好吗
答：定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系
