限制性定语从句与非限制性定语从句的区别
类别
意义
功能
形式
关系代词
限定性定语从句
起限定作用。若省略，原句意义不完整。
修饰先行词
无逗号隔开
1.有that
2.作宾语时可以省略非来自定性定语从句起补充说明作用。若省略，原句意义不受影响。
修饰先行词/
整个句子
有逗号与主句隔开
无that
对这两个词作如下归纳：
1、如果从句在主句前，不能用which引导定语从句。如：
As we all know, his parents were killed in the war.
As we all know, the earth is round.
2. as引导定语从句通常用在一些固定的句型中,如:
不可以省略
有时同一个限制性从句变为非限制性从句会改变全句的意思。
1）. A. I have a sister who works in a hospital.
我有一位在医院工作的姐姐。（可能还有其他的姐姐）
B.I have a sister, who works in a hospital.
我有一位姐姐，她在医院工作。（只有一位姐姐）
例如：
He issuch a good teacher as every student likes very much.
如果用such...that...则应该说：
He is such a good teacher that every student likes himvery much.
