以下是店铺整理的非限制性定语从句，欢迎大家借鉴与参考，希望对大家有所帮助。
非限制性定语从句 1非限制性定语从句：即非限定性定语从句，起补充说明作用，缺少也不会影响全句的理解，在非限定性定语从句的前面往往有逗号隔开，如若将非限定性定语从句放在句子中间，其前后都需要用逗号隔开。
由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。
As一般放在句首，which在句中。
使用规则及注意事项：1、which引导的非限定性定语从句是用来说明前面整个句子的情况或主句的某一部分。
2、as有时也可用作关系代词。
as引导非限制性定语从句，若as在从句中作主语，其引导的句子可以放在句首，也可以放在句中。
但which引导的非限制性定语从句只能放句中。
例句：As is reported in the newspaper, some artistic treasures (艺术珍品) will be on show at the exhibition on the weekend.3、在非限定性定语从句中，关系词不能用that。
限制性定语从句和非限制性定语从句有四大区别：1在句中作用不同限制性定语从句对被修饰的先行词有限定制约作用，使该词的含义更具体，更明确。
限制性定语从句不能被省略，否则句意就不完整。
非限制性定语从句与先行词关系不十分密切，只是对其作一些附加说明，不起限定制约作用。
如果将非限制性定语从句省去，主句的意义仍然完整。
2外在表现形式不同限制性定语从句因与先行词关系密切，所以不可以用逗号将其与主句隔开;而非限制性定语从句与先行词关系不十分密切，所以可用逗号将其与主句隔开。

什么是非限制性定语从句
什么是非限制性定语从句定语从句有限制性和非限制性两种。
限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，将非限定性定语从句放在句子中间，其前后都需要用逗号隔开。
非限制性定语从句可以简单理解为就是没有紧跟在修饰对象（即先行词）之后的定语从句，与限制性定语从句刚好相反。
也就是说，先行词和非限制性定语从句之间常被逗号或是其它语句部分隔开，而没有紧密连接在一起。
需要注意的是：1)引导词that(关系代词)和why(关系副词)一般不用于引导非限制性定语从句。
2)引导词which(关系代词)在引导非限制性定语从句时，不仅可以指代主句的某部分内容，还可以用来指代整个主句。
具体示例如下：（下划线部分是非限制性定语从句；加粗字体是该定语从句的修饰对象，也就是先行词。
）例1：I am looking for a watch, which Jason bought me.例2：The puppy peed in his arms, which made us laugh.例3：Penny, who used to be a waitress, becomes a successful saleswoman.例4：Many people witnessed the accident, some of whom called the police.例5：Jacob is the silent boy standing in the back, whose hair is black and straight.例6：He realized the days were all over when they could talk everything to each other.例7：She wandered in the school alone and aimlessly, where they last met.值得注意的是，由于定语从句的本质是形容词，通常只起到修饰作用，所以定语从句本身一般不会对主句的完整性产生任何影响。
非限制性定语从句
非限制性定语从句1. 定义非限制性定语从句（Non-restrictive Relative Clauses）是指用来修饰一个名词或代词，且不对其进行限定的定语从句。

非限制性定语从句和限制性定语从句的区别在于非限制性定语从句用逗号或破折号将其与主句分隔开来，而限制性定语从句则不用分隔符。
例如：•限制性定语从句：The book that I borrowed last week was very interesting.•非限制性定语从句：My friend, who is a doctor, came to visit me.非限制性定语从句通常用来提供额外的信息，使得整个句子更加丰富和具体。
