非限制性定语从句
(1)限制性定语从句和主句的关系十分密切， 若省去，主句的意思就不明确。主从句之间 不用逗号隔开。而非限制性定语从句则不然。 试比较：
This is the best book that I have read. This is a good book, which is easy to understand.
(2) as多用于下列习惯用语中 as anybody can see 正如人人都能看到的那样 as is well known = as is known to all 众所周知 as we had expected 正如我们所预料的那样 as often happens 正如经常发生的那样 as has been said before 如上所述 as is mentioned above 正如上面提到的
(5)关系代词在非限制性定语从句中作介词的宾语 时，介词前可以有被介词短语所修饰的词。如： He has two daughters, the elder of whom is married. (6)在非限制性定语从句中，关系代词还可以 作介词的宾语。 He is ill, in spite of which he keeps on studying.
3. 关系代词as, which引导非限制定语从句时的区别
(1)as和which都可指主句的整个意思，而不是主 句中的某一个词。as引导的非限制性定语从句， 既可在主句前，又可在主句后，有时还可插入主 句中；而which引导的非限制性定语从句一般置于 主句之后。如： The weather turned out to be very good, which was more than we could expect. As is known to all, the moon travels round the earth.

既然有非限制性定语从句，肯定有限制性定语从句。
两者分别是什么样的定语从句呢?又有什么区别呢?那接下来我们就从区别入手，学习一下限制性定语从句和非限制性定语从句吧。
定语从句的基本结构为：先行词+关系代词或关系副词+从句本身。
定语从句可以是限制性的，也可以使非限制性的，它们主要有以下区别：1.结构上的区别限制性定语从句和非限制性定语从句在结构上基本相同。
在口语中，非限制性定语从句的先行词和关系代词或关系副词之间稍有停顿。
在文本中，限制性定语从句不用逗号与主句隔开，而非限制性定语从句需使用逗号和主句隔开。
例a)：I have a sister who is a doctor.(限制性定语从句)我有一个当医生的姐姐。
例b)：I have a sister, who is a doctor.(非限制性定语从句)我有一个姐姐，她是当医生的。
2.意义及功能上的区别从意义上分析，非限制性定语从句是对先行词的附加补充说明。
如果删去，不会影响主句意义的完整。
而限制性定语从句修饰和限制先行词，明确先行词内容，是先行词不可缺少的定语。
如果删去，会影响主句意义的完整。
例c)：I have an elder brother who is a teacher.(限制性定语从句)我有一个当老师的哥哥。

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。
非限制性定语从句知识点总结
非限制性定语从句知识点总结在英语语法的学习中，非限制性定语从句是一个重要且相对复杂的知识点。
为了帮助大家更好地理解和掌握这一内容，下面将对非限制性定语从句的相关要点进行详细总结。
一、非限制性定语从句的定义非限制性定语从句是一种对先行词进行补充说明的从句，它与先行词的关系较为松散，即使去掉从句，主句的意思仍然完整。
例如：“My father, who is a doctor, works very hard”在这个句子中，“who is a doctor”就是一个非限制性定语从句，先行词是“my father”。
即使去掉这个从句，“My father works very hard”这个主句的意思也是清晰完整的。
二、非限制性定语从句的特点1、逗号分隔非限制性定语从句与先行词之间通常用逗号隔开，这是其与限制性定语从句在形式上的一个明显区别。
比如：“The house, which was built in 1980, is very old”2、先行词可以是整个主句非限制性定语从句的先行词不仅可以是一个名词或代词，还可以是整个主句。
例如：“He failed the exam, which made his parents very disappointed” 这里先行词就是“He failed the exam”整个句子。
3、关系词的使用（1）关系代词：which、who、whom、whose 等。
which 指代物，在从句中可作主语、宾语等。
who 指代人，在从句中作主语。
whom 指代人，在从句中作宾语。
whose 表示“……的”，在从句中作定语。
（2）关系副词：when、where 等。
when 指代时间，在从句中作时间状语。
where 指代地点，在从句中作地点状语。
需要注意的是，非限制性定语从句中不能使用 that 作为关系词。
