英语语法：限定性定语从句，和非限定定语从句的区别，太简单了

Do you know the professor who is speaking at the meeting? （限制性定语从句）
English is an important subject, which every student should study well. （非限制性定语从句）
二、 先行词不尽相同
限制性定语从句的先行词往往是某一个词，但非限制性定语从句的先行词可以是一个词，也可以是句子的一部分，甚至是整个主句，此时非限制性定语从句一般由which或as引导，as引导非限制性定语从句常用在as is said / known / expected / mentioned / reported / announced等结构中。如：
He has passed the college entrance examination, which makes his parents quite happy.
As is known to everybody, the moon travels round the earth once every month.
三、 关系词的使用情况有所不同
1． that 不可引导非限制性定语从句。如：
Her father gave her a computer for her birthday，which pleased her a lot.
2． why 不用在非限制性定语从句中，需用for which代替。如：
I told them the reason, for which I didn't attend the party last week.
3． 关系代词替代情况不同
关系代词 whom 在限制性定语从句中作宾语时可用 who 代替 whom, 但 whom 在非限制性定语从句中作宾语时不可用 who代替。如：
This is the girl whom (who) I have been in love with for six years.
The young man had a new girl friend, whom he wanted to show all his love for.
4． 关系代词省略情况不同
关系代词在限制性定语从句中作宾语时可以省略；非限制性定语从句的所有关系代词均不可省略。如：
She is the new student (whom / who / that) I want to introduce to you.
All the books there, which have beautiful pictures in them, were written by him.
四、 下列情形用非限制性定语从句
1. 当“不定数量词 (如some, several) ／ 数词 ＋ of which ／ whom”表示“整体 (which ／ whom)中的一部分”的概念时。如：
We saw many animals in the zoo, some of which are tigers．
There are fifteen new players in our team, two of whom come from Canada.
2. 当先行词为专有名词或被物主代词和指示代词修饰时，其后的定语从句通常是非限制性的。如：
My house, which I bought last year, has got a lovely garden.
Qingdao, where I have been three times, is an attractive city to foreigners.

限制性定语从句
非限制性定语从句
All the students who study hard have passed.学习努力的学生都考试及格了。(只有努力的及格了，不努力的没及格。) All the students ,who study hard have passed.所有的学生都及格了，他们学习努力。（没有人不及格，这些学生都很努力。）
从句是先行词不可缺少的定语（如去掉，主句意思就不完整或不正确。） 从句是对先行词的附加说明（如去掉，主句意思仍清楚，不受影响。） 与主句关系密切，不用逗号 与主句关系不十分密切，用逗号与主句隔开译为汉语时，从句译在先行词前，与先行词用“的”连接 译为汉语时，从句放在主句后面关系代词that可以代替who、whom(指人)、which(指物) 关系代词不用that,只用who、whom(指人)、which(指物) 关系代词代替宾语时可以省略 关系代词不能省略关系代词as和which
先研究下面两个例句：
○1.This elephant is like a snake, as /which everybody can see. =As everybody can see, this elephant is like a snake. 任何人都看得出来，这头象像条蛇。
○2.Tom didn’t pass the physics exam, which made his parents very angry. Tom物理考试不及格，这使得他父亲很生气。
这两个例句中，as和which所代表的都是整个主句所表示的内容。但有两点不同之处：
1． 在形式上as引导的非限制性定语从句可位于主句的后面，也可位于主句的前面；而which引导的非限制性定语从句只能位于主句的后面，不能位于主句的前面。
2． 在意义上，as引导的定语从句和主句的关系一般为一致关系，常译为“正如……”，“就像……”，而which引导的定语从句和主句的关系是因果关系，或which引导的定语从句是对主句的评论。因此，在意思通顺的情况下，which可代替as，而as许多时候不能代替which，如句○2。再如：
1．He was late again, as / which we had expected. =As we had expected, he was late again. 正如我们所料，他又迟到了。/他又迟到了这是我们早就料到的。
2． The street hasn’t been cleared for weeks, which makes it very dirty. 街道好多星期没有打扫了，因此整条街很脏。（不用as）
3．The young man cheated his friend of much money, which was disgraceful. 那年轻人诈骗了他朋友许多钱财，这是不光彩的。（不 用as）
4．He takes exercise everyday, which has done a lot of good to his health. 他每天运动，这对他的身体很有好处。（不用as）
5．As has already been pointed out, English is rath
