2.All the books that you offered has been given out.
3.This is the best film that I have ever read.
4.We talked about the persons and things that we remembered.
5.He is the only man that I want to see.
6.Who is the man that is making a speech?
只用which, who, whom的情况
1.在非限制性定语从句中，只能用which指代物，用who/whom指人
2.在由“介词+关系代词”引导的定语从句中，只能用which指物，whom指人。
3.先行词本身是that时，关系词用which, 先行词为those, one, he时多用who。
1.He has a son, who has gone abroad for further study.
2.I like the person to whom the teacher is talking.
3.Those who respect others are usually respected by others.
III. as、which和that的区别
从句
区
例
限制性
定语从句中
名词前有such和the same修饰时，关系代词用as,不能用which
He is not such a fool as he looks.
Don’t read such books as you can’t understand.
非限制性
定语从句中
as和which都可以指代前面整个主句。如果有“正如，象”的含义，并可以放在主句前，也可以放在后面，那么用as；而which引导的从句只能放主句后，并无“正如”的意思。
They won the game, as we had expected.
They won the game, which we hadn’t expected.
As is well known, he is a famous film star in the 1980s.
the same... as和
the same ...that
the same... as指同类事物
the same ...that 指原物
That’s the same tool as I used last week.（同类工具，不是同一把）
That’s the same tool that I used last week.那就是我上周用过的工具。
注意：the way 做先行词时，定语从句可由that, in which 引导或不用引导词。
IV.定语从句与其它从句（句型）的区别

并列句
定语从句与并列句的主要区别在于：并列句有像and，but，so等并列连词或两个句子用分号连接，这时就不能再用引导定语从句的关系词了。
①Mr Li has three daughters，none of _____ is an engineer．
②Mr Li has three daughters，but none of _____ is a dancer．
从结构上看，①小题是定语从句，故填whom；
②小题有并列连词but，是并列句，故填代词 them。

状语从句
定语从句的前面有名词作先行词，而状语从句没有先行词。
This is the place where we used to live a few years ago.
这是几年前我们居住的地方。（定语从句，先行词为the place）
Let’s go where we can find a better job.
我们到能找到更好的工作的地方去吧。（地点状语从句）
定语从句修饰、限制、说明名词，只能放在先行词的后面，而状语从句说明动作发生的情况，并且可以放在主句的前面。
Do you know the time when the class is over? 你知道下课的时间吗？（定语从句）
It was already five o’clock when the class was over.
=When the class was over, it was already five o’clock.
当下课时己经是5点了。（时间状语从句）
When, where和why在引导定语从句时可以用“介词＋which”的结构来替换，在引导状语从句时却不行。
This is the factory in which (where) his father once worked.
这就是他的父亲曾经工作过的那个工厂。（定语从句）
Put back the book where it was. 把书放回原处。（状语从句）
定语从句中的关系词在从句中充当某种句子成分，因此去掉它则从句成分不完整；而结果状语从句中的连接词在从句中不作任何成分，去掉后从句的成分仍然完整。
It is such an interesting book as we all like. 它是我们大家都喜欢的如此有趣的书。
（as用作动词like的宾语，它引导的是定语从句）
It is such an interesting book that we all like it.
它是一本如此有趣的书，我们大家都喜欢它。
