怎样写出一个 非限定性定语从句 ?教教我呗!我想在作文中应用这个句式,可是又不会!

我觉得网上讲的都挺详细了,以后有这样的问题可以去直接去百度搜,很容易找到答案的,一般来说第一页前两三个就有.又不用等了
我就把网上的发来吧
非限定性定语从句的作用是对所修饰的成分作进一步说明,通常是引导词和先行词之间用逗号隔开,将从句拿掉后其他部分仍可成立
1.which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分
2.当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的,例如：
Charles Smith,who was my former teacher,retired last year.查理·史密斯去年退休了,他曾经是我的老师.
My house,which I bought last year,has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园.
This novel,which I have read three times,is very touching.这本小说很动人,我已经读了三遍.
3.非限制性定语从句还能将整个主句作为先行词,对其进行修饰,这时从句谓语动词要用第三人称单数,例如：
He seems not to have grasped what I meant,which greatly upsets me.他似乎没抓住我的意思,这使我心烦.
Liquid water changes to vapor,which is called evaporation.液态水变为蒸汽,这就叫做蒸发.
4.有时as也可用作关系代词
5.在非限定性定语从句中,不能用关系副词why和关系代词that,而用who,whom代表人,用which代表事物.；
限制性定语从句与非限制性定语从句
1．限制性定语从句说明先行词的情况,对先行词起限定作用,与先行词关系十分密切,不可用逗号隔开,也不可省略,否则全句意义就不完整.如：
This is the telegram which he refers to.
Is there anything (that) I can do for you?
2．非限制性定语从句只是对先行词作补充说明,没有限定作用,它与先行词的关系比较松散,因而不是关键性的,如果省略,原句的意义仍然完整.这种从句在朗读时要有停顿,在文字中通常用逗号与主句隔开.如：
This note was left by Tom,who was here a moment ago.
As a boy,he was always making things,most of which were electric.
引导非限制性定语从句的关系词有：who,whom,whose,which,when 和 where,不可以用that和why.
另外,非限制性定语从句从意义上讲,相当于一个并列句,在口语中使用并不普遍,在日常生活中,人们通常用并列句或简单句来表达.如：
I told the story to John,who later did it to his brother.
= I told the story to John,and he later told it to his brother.
Yesterday I happened to see John,who was eager to have a talk with you.
= Yesterday I happened to see John and he was eager to have a talk with you.
3．两种定语从句的内涵不同,限制性定语从句具有涉他性,而非限制性定语从句具有 唯一性,这在理解和翻译时应特别注意.试比较：
All the books there,which have beautiful pictures in them,were written by him.
All the books there that have beautiful pictures in them were written by him.
His brother,who is eighteen years old,is a PLA man.（只有一个）
His brother who is a PLA man is eighteen years old.（不止一个）
4．有时,非限制性定语从句所修饰的不是某一个词,而是整个主句或是主句中的一个部分,这时一般采用which或as来引导.如：
He passed the exam,which/as he hoped he would.
注：（1）as引导的从句可以放在主句之前,而which引导的从句只能放在主句之后.
They are hollow,which makes them very light.
As is known to all,Taiwan is a part of China.
（2）从意义上讲,which指前面主句的内容；而as指代的是作为一般人都知道的常
识性的东西,因此常译成“就象… …那样”.
（3）如果定语从句的内容对主句的内容起消极作用,则用which,而不用as,如：
She stole her friend’s money,which was disgraceful.
He tore up my photo,which upset me.
5．在正式文体中,以the way为先行词的限制性定语从句通常以in which或 that 引导,如：
The way in which you answered the questions was admirable.
但在非正式文体中,人们通常省略in which或 that :
The way (in which) he spoke to us was suspicious.
I don’t like the way (that) you laugh at her.

I was late yesterday, which made my teacher angry.

He lost his way, which delayed him considerably
