关系代词that 的用法

(1)不用that的情况

(a) 在引导非限定性定语从句时。

(错)The tree, that is four hundred years old, Is very famous here. (b) 介词后不能用。

We depend on the land from which we get our food. We depend on the land that/which we get our food from. (2) 只能用that作为定语从句的关系代词的情况

(a) 在there be 句型中，只用that，不用which。

(b) 在不定代词，如：anything, nothing, the one, all等作先行词时，只用that，不用which。

(c) 先行词有the only, the very,the same,the last,just修饰时，只用that。 (d) 先行词为序数词、数词、形容词最高级时，只用that,不能用which。. (e) 先行词既有人，又有物时。 (f) 先行词指物，在主句中作表语时．

(g) 为了避免重复．

(h)先行词是the way或the reason时，that可作关系副词，也可省略 (i) 主句的主语是疑问词who /which时 举例：

Is this the book that you borrowed in the library? 这是你在图书馆借的那本书吗？

Who that break the window should be punished． 谁打碎了窗户都要受到惩罚．

All that is needed is a supply of oil. 所需的只是供油问题。

Finally, the thief handed everything that he had stolen to the police. 那贼最终把偷的全部东西交给了警察。 that必用

1先行词是最高级或被最高级修饰 2是序数词或被序数词修饰 3不定代词

4先行词即指人又指物

5被only；the every，no，one of等修饰 6主句有which；who；whom 7there be 句型中

8如果有两个从句，其中一个关系代词已用了which,另一个关系代词宜用that 9先行词在主句中作表语，或者关系代词本身作从句的表语是宜用that that在作宾语时可省 难点分析

（一）限制性定语从句只能用that的几种情况 1、当先行词是anything, everything, nothing (something 除外), few, all, none, little, some等代词时，或者是由every, any, all, some, no, little, few, much，each等修饰时 (1) Have you taken down everything (that) Mr. Li has said?

(2) There seems to be nothing (that) seems impossible for him in the world.






(3) All that can be done has been done.

(4) There is little (that) I can do for you.

注意1：部分时候that可以省略，如部分例句将that用括号括住。 注意2：当先行词指人时，偶尔也可以用who

(4) Any man that/.who has a sense of duty won’t do such a thing. 2、当先行词被序数词修饰

The first place that they visited in London was the Big Ben. 3、当先行词被形容词最高级修饰时 This is the best film that I have seen.

4、当形容词被the very, the only，the same,the last 修饰时

(1) This is the very good dictionary that I want to buy,

(2) After the fire in his house, the old car is the only thing that he owned. 当先行词指人时，偶尔也可以用who

(3) Wang Hua is the only person in our school who will attend the meeting？

5、当先行词前面有who, which等疑问代词时 (1) Who is the man that is standing there? (2) Which is the T-shirt that fits me most? 6、当先行词既有人，也有动物或者物体时

Can you remember the scientist and his theory that we have learned? 7.当关系代词在定语从句中做表语

The village is no longer the one that it used to be 10 years ago. 8.当在there be句型中，通常情况下用that，不用which

（二）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，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者宾语，代表前面整个句子。 (1) He married her, as/which was natural. (2) He was honest, as/which we can see.

2、as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which引导的非限制性定语从句只能放在主句之后。另外，as有“正如……，正像……”的意思

(1) As is known to all, China is a developing country. (2) He is from the south, as we can see from his accent.

(3) John, as you know, is a famous writer.

(4) He has been to Paris more than several times, which I don’t believe. 注意：当主句和从句存在逻辑上的因果关系时，常用which。 (5) Tom was always late for school, which made his teacher angry. 3、当先行词受such, the same修饰时，常用as (1) I have never heard such a story as he tells. (2) He is not such a fool as he looks.

(3) This is the same book as I lost last week.

注意：当先行词由the same修饰时，偶尔也用that引导定语从句，但是和由as所引导的定语从句意思不同

(4) She wore the same dress that she wore at Mary’s wedding. 她穿着她在MARY婚礼上穿过的一条裙子。






(5) She wore the same dress as her young sister wore. 她穿着和她妹妹所穿的一样的裙子。

注意：定语从句such…as …与结果状语从句such… that…的区别：as在所引导的定语从句中作主语，宾语；that在结果状语从句中不做成分 (6)He has such a good laptop as I want to buy.

(7)He has such a good laptop that I want to buy one.

(三）以the way为先行词的定语从句通常由in which, that引导，而且通常可以省略。

The way in which/ that/./ he answered the question was surprising. (四) but有时也可以做关系词引导定语从句

There are very few but understand his idea。 ( but= who don’t ) (五) 区分定语从句和同位语从句

1、定语从句修饰先行词，它和先行词是修饰关系； 同位语从句说明先行词的具体内容，是补充说明的关系 (1) The plane that has just taken off is for London. 定语从句 (2) The fact that he has been dead is clear. 同位语从句

2、定语从句由关系代词或者关系副词引导，关系词在句中充当成分，有时可以省略；

同位语从句主要由that引导，在句中一般不做成分；

句子也可以由when, where, how, why, whether, what等词引导，充当成分 (1) The news he told me is true.

(2) The news that he has just died is true.

(3) The problem that we are facing now is how we can collect so much money. 定语 (4) The problem how we can collect so much money is difficult to solve.

3、 同位语从句和先行词一般可以用be动词发展成一个完整的句子，而定语从句不可以发展成一个完整的句子，

(1) The idea that we could ask the teacher for advice is wonderful. 同位语

(2) The idea was that we could ask the teacher for advice.

(3) The fact that the moon moves around the earth is known to all. (4) The fact is that the earth moves around the earth. ［定语从句］介词+关系词

1）介词后面的关系副词不能省略。

2）that前不能有介词。

3）某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。例如：

This is the house in which I lived two years ago. 这是我两年前住过的房子。 This is the house where I lived two years ago.

Do you remember the day on which you joined our club？ 还记得你加入我们俱乐部的那一天吗？

Do you remember the day when you joined our club？
