Nte1:定语从句：当我们把一个句子用来做________去修饰一个_____________时，这个句子就称为定语从句。Nte2:被定语从句限定的词叫做_________,引导定语从句的词叫做___________，分别是_______________和___________。
跟在名词或代词后面起修饰限制作用的从句
Restrictive Relative Clause 限定性定语从句
wh/whm/that/省略
whse(=f whm)
that/which/省略
whse(=f which)
Ps: 关系词在从句中做状语时, 连接词有时可以用介词+which/whm来替换关系副词
判断句子是否为定语从句划出先行词将先行词代入从句，看它在从句中所担任的成分根据先行词在从句中所作成分，得出关系词
1. That is the by ______ mther is a famus musician.
3. The huse _______ they built in 1987 was destryed in the earthquake.
2. We dn’t knw the number f peple ________ lst their hmes in the 1906 earthquake.

4. I’ll never frget the day _____ (=___ which ) I was brn.
5. I visited the huse _____ (=__ which) Lu Xun nce lived.
6. The reasn _____(=___ which) he gt wrried was this.
（一）限制性定语从句中关系代词的用法
a. The man (wh) I talked with is ur teacher.b. The man (whm/wh) I ndded t is Mr. Li.c. These are the trees which were planted last year.d. A plane is a machine that can fly.e. This is the scientist whse achievements are well knwn.
引导限制性定语从句的关系代词有：wh(人), whm(人), which(物), that(人/物), whse(人/物), 在从句中作主语、宾语、表语或定语。
关系代词在从句中作宾语时可省略
① I like the way (in which / that) yu smile.② I dn't like the way (in which / that) he's lking at me. ③ This is the way (in which / that) we've always dne it.
当先行词是way且在从句中表示“以……方式”时，常由that或in which引导定语从句，引导词也可以省略。
① I am sure she has smething (that) yu can brrw.② Did yu have anything (that) yu want t say fr yurself?
(1)先行词为all, everything, nthing, smething, anything, little, much, nne, sme 等不定代词时。
that和which在指物的情况下一般都可以互换， 但在下列情况下，一般用that而不用which。
用that而不用which的情况
① This is the very bus (that) I'm waiting fr.② The nly thing (that) we can d is (t) give yu sme mney.③ I've read all the bks that are nt mine.
(2)先行词被the nly, the very(恰恰，正好), the same, the last, all, every, n, sme, any, little, much等修饰时。

(5) 当主句的主语是疑问词wh或which时。
① Which is the bike that yu lst? ② Wh is the by that wn the gld medal?
(6) 有两个定语从句时，其中一个关系代词宜用which，则另一个用that。
They secretly built up a small factry, which prduced things that culd cause pllutin.
（二）限制性定语从句中关系副词的用法
关系副词（when, where, why）引导定语从句时，既引导定语从句，又在定语从句中充当状语。关系副词可转化为介词+关系代词(which)结构。
a. He tld me the date when (n which) he jined the Party.b. The htel is the ne where (at which) I stayed last mnth.c. I knw the reasn why (fr which) she was s angry.
Nn-restrictive Relative Clause 非限定性定语从句
Water, which is a liquid, has many uses.
非限制性定语从句对先行项进行补充说明，由关系代词或关系副词引导。主语和从句用逗号隔开。
（一）非限制性定语从句中关系代词的用法
非限制性定语从句由which, wh, whm, whse等关系代词引导。
a. Peter, wh had been driving all day, suggested stpping at the next twn.b. I want t buy a dictinary, which is valuable t my learning.c. My brther, whm/wh yu met the ther day, has gne abrad.d. Mrs. Gray,  whse children are in cllege, is trying t get a jb.

非限制性定语从句中，可用关系副词when, where引导。
a. He will put ff the picnic until May 1st, when he will be free.b. Yesterday I went t the department stre, where I met my teacher.
1. 限制性定语从句它是对先行词作修饰、限制, 从句与主句的关系十分密切, 如果去掉, 主句的意思就不完整或失去意义。
2. 非限制性定语从句它是对先行词作附加补充说明, 从句与主句的关系不是很密切, 如果去掉, 主句的意思仍然清楚、完整。
His daughter, wh is in Shenzhen nw, is cming hme next week.
Peple wh take physical exercise regularly live lnger.
区分限制性定语从句与非限制性定语从句
限制性定语从句: 与主句之间无逗号隔开；非限制性定语从句: 与主句之间有逗号隔开。
限制性定语从句: 可以修饰名词或代词；非限制性定语从句: 可以修饰名词或代词, 也可以修饰整个句子
在限制性定从, 关系代词作宾语时可以省略；在非限制性定从, 所有关系词都不可省略。不可使用that，why (应使用fr which）
