定语从句具体怎么用？
解题思路： 用法
解题过程：
高考英语语法精讲 （1）考点1：①定语从句的本质：修饰某一名词或代词的从句叫定语从句或形容词从句；整个从句修饰这一名词 ②被定语从句修饰的名词或代词叫先行词 a. God helps those(先行词) who help themselves（定语从句）. b. I like the girl（先行词） who speaks English very well. c. You must do everything(先行词)that I do（定语从句） . ③关系代词和关系副词的作用： 连接作用（连接主句和从句）；替代作用（替代先行词）；成分作用（必须在定语从句中充当成分）
（2）考点2：用关系代词还是关系副词
① 定语从句解题技巧：（三步） I．找出连接词 II．找出主句----分析主句成分----确定从句类型 III．立即将先行词直接带入从句---分析从句成分---分析先行词在从句中的成分 ②关系代词和关系副词

（3）考点3：关系代词和关系副词的特殊情况
1．指物时只用 that，不用which 的情况： （代高序修饰时）
1)当先行词为 all, much, little, few, none, something, anything, everything, nothing 等不定代词时。
①All that can be done has been done.
所有能做的已经做了。
②There must be something that happened to you. 你一定出了什么事。
2)先行词被序数词或形容词的最高级或the last, the only ,the very,等修饰。
①That is the only way that leads to your success.
那是通向你成功的唯一之路
②We have to consider the first thing that starts our work.
我们必须要考虑启动我们工作的第一件事。 ③This is the most impressive TV theater that has never been put on show before. 这是以前从未上演过的最有感染力的电视剧。
3).在疑问词 who, what, which 开头的句子中。（避免歧义）
Who is the girl that is talking with Mr.Brown.
4).定语从句为there be句型，也可以省略。
This is the fastest train (that) there is to Beijing .
5). 当先行词既指人又指物时。 We are talking about the people and countries that we have visited.
6).当关系代词在定语从句中做表语。
China is not the country(that)it was.
Mary is no longer the girl that she used to be.
2. 只能用 which 不能用 that 的情况。
1). 引导非限定性定语从句修饰某物或整个句子。
Bruce went towards the fire, which was still smoking.
Tom came back late, which made his parents very angry.
2).在介词后面:介词+which (先行词是物)
The world in which we live is made of matter.
注意:若介词在从句中而没有直接在关系词后,可以用which 或that.
例如: The world that we live in is made of matter.
3.指人时只能用who不用that 的情况.
1)先行词为one,ones或anyone.(避免歧义)
2)先行词为those.(避免歧义)
God helps those who help themselves.(天助自主者)
3)主句是there be . Eg:There is a man who called himself Mr.Wu at the gate.
4)在非限制性定语从句中
注意:4. “the same …as”. Such/so…as”中的as 可以指人或物,作从句的主语、宾语、表语或介词的宾语。
如：Such money as he earned was spent on spirits and tobacco.
Is this the same mosquito as bit you just now?
He was not half such a coward as we took him for.
相关考点：
1．So/such…that …(状语从句)
She is so beautiful a girl that I love her so much.(状语从句)
She is so（定语从句）beautiful a girl as I love so much .
2.as的考点总结：as可以作为关系代词引导限定性定语从句、非限制性定语从句。例如：限定性定语从句（常用于such/so…as 和the same 。。。as等句式中 ）
Such points as you’ve mentioned are really important in solving the problem.
你提到的这些方面在解决这个问题上的确很重要。
People such as you describe are rarely seen nowadays.
你描述的这种人现在很少见了。

非限制性定语从句（as可以作为关系代词引导非限制性定语从句时，as指代整个主句：也就是说，将整个主句看成一件事或是一个事实；并对其进行补充说明。这种非限制性定语从句既可以放在主句之前，也可以放在主句之后。）
As I know, she hasn’t got married.如我所知，她还未结婚。
They won the first place in the game, as could be expected.可以预料，他们在比赛中得了第一。 Professor Li is extremely popular among students, as is known to all of us .如我们大家所知，李教授极受学生们的欢迎。 5.当其先行词是reason时，关系副词用why(=for which )或that 引导表示原因的定语从句。(相关考点：名词从句）当主句主语是reason时，作主句表语的成分不能有because 或because of 。其结构一般为the reason why…is that…, the reason that … is that …, He did not tell us the reason why he was late again. The reason why (that) he didn’t come is that he was ill. Didn’t tell her the reason why he was so happy. 他没有告诉她为什么他那么高兴的原因 The reason why she was late is not so acceptable. 她迟到的原因不那么令人接受。 They explained the reason to us why they had misunderstood us before. 他们向我们解释为什么他们以前误解了我们的原因。 6．当way表示方式作先行词时，其关系副词不能用how,而要用that 或in which在非正式英语中可以不用连接词。 The way that he considered the problem was too unacceptable. I don’t like the way you talked to your mother.
（4）考点4：在“介词+which/whom”的结构中，介词的选择 方法1.看定语从句中动词或形容词与介词的搭配 1.He is the man __on__ whom I think you can depend. 2.He referred me to some reference books __with__ which I am not very familiar. 方法2.看从句中的动词或动词词组与先行词的搭配 1.He made a hole in the wall, through which he could see what was going on outside the house. 2.

考点5：非限制性定语从句
非限制性定语从句不能用that引导，一般用引导词which/as/who,非限制性定语从句既可以修饰主句的部分内容，也可修饰主句的全部内容。As引导的非限制性定语从句既可以放在主句之前，也可以放在主句之后，但which或who引导的非限制性定语从句不能放在主句句首。
As we all know, the moon is a satellite of the earth.
The large area is covered with thick snow, which affects people’ life greatly.
His speech, which bored us to death, was over at last.
Her sister, who lived in another city, was coming to visit her.
关于非限制性定语从句，应该注意：
1.关于非限制性定语从句和单句的比较

He failed in the exam. That made his parents angry.
Vs. He failed in the exam, which made his parents angry.
He has two sons. Both of them are teachers.
Vs. He has two sons, both of whom are teachers.
2. as 引导的非限制性定语从句与it。
The earth is round. It is known to all.
比较：The earth is round, which is known to all.
As is known to all, the earth is round.
比较： It is known to all that the earth is round.
As具有“正如”之意，搭配的动词一般是固定的，如as you know/as you see/as we planned/as we expected/as is reported….
3.as引导的限制性定语从句与其他从句的比较。
(状语从句)This is such an interesting book that we all like it.
（定语从句）This is such an interesting book as we all like
