总结：which和as的区别
as 和which在引导非限制性定语从句时，这两个关系代词都指 主句所表达的整个意思，且在定语从句中都可以作主语和宾语。 但不同之处主要有两点：
①as引导的定语从句可置于句首，而which不可。 ②as代表前面的整个主句并在从句中作主语时，常可翻译 为“正如，正像”；而which常译为“这一点，这件事” ③ 在限制性定语从句中，如果先行词被as, so ,the same, such 修 饰时，关系代词常用as
which
which和as的区别

助他的理由吗？ 2）that代替关系副词
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和" 介词+ which"引导的定语从句，在口语中that常被省略，例如：
His father died the year (that / when / in which) he was born. 他父亲在他出生 那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。
3 判断关系代词与关系副词
方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面 无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如：
Do you remember the day when you joined our club
第3页，共11页。
Beijing is the place where (in which) I was born. 北京是我的出生地。 Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮
1 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。关系代 词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 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是我昨天见的那个人。（whom/that在从句中作宾语）
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和" 介词+ which"引导的定语从句，在口语中that常被省略，例如：

今天的话题就是定语从句，即一个句子放在一个词的后面修饰 该词，这个句子就叫定语从句。 学习定语从句需要牢牢把握三点：
第一，定语从句和被修饰词之间要有一个连接词连接，该词
在语法上被称之为“关系代词或副词”；
第二，被定语从句修饰的词语，在语法上被称之“先行
词”，该“先行词”的作用是：在后面的定语从句中充当某
以下情况只能用“that”作关系代词：
1.先行词既有指人又有指物； 2.当先行词前有序数词或形容词最高级 时或有the only, the very等修饰时； 3.先行词是all, much, anything, something, nothing等不定代词； 4.主句是以who/which开头的特殊疑问句 时；
