前置定语：单词：名词、形容词、分词、动名词后置定语：短语和从句（定语从句）

中文有没有后置定语？古文中有后置定语，现代汉语几乎没有。居庙堂之高则忧其民，处江湖之远则忧其君。英文：英文长句中后置定语居多。
后置定语：短语和从句（定语从句）
前置：I like hnest students.定语从句：I like the students wh are hnest.
She is the ne that yu never frget.见过她你便永远不能忘记。She is the heaven-sent angel yu met.见过她你便知道她是天使。She must be the reasn why Gd made a girl.她就是上帝制造女孩的原因。She wins everything that she might d.只要她愿意它可以得到一切。
定语从句：在英语中，我们通常用一个形容词作定语修饰名词或代词，若要表达更复杂的意思，为了避免头重脚轻，则需要借助一个句子来修饰名词。这个被修饰的名词/代词因为总在定语从句前面，所以被称为先行词。引导定语从句的词，就被称为关系词。
定语从句三个重要概念：1.先行词：被定语从句所修饰或限制的对象。2.关系词：连接主从句，在从句中充当一定成分（替代先行词）。3.定语从句。 Everything that we saw in this film was true.
①找出两个简单句的共有成分；②将从句中的共有成分去掉；③用关系词引导剩下的从句，并紧接在被修饰词之后．
I lve the girl. The girl has lng hair.
I lve the girl wh has a lng hair.
关系代词that, which , whm 在从句中作宾语时可省略掉。但放在介词后面只能用whm/which而且不可省略。
1. 先行词为all， everything，nthing，smething，anything，little，much等不定代词
2. 先行词被序数词或最高级修饰
3. 先行词既有人又有物
4. 先行词被the nly，the very，the last，just，right等修饰
5. 开头是wh或which引导的特殊疑问句
1. 先行词是ne，nes，anybdy，anyne，all，nne，thse等，指人一般用wh，不用that
2. 非限制性定语从句中，指人用wh和whm， 指物只能用which，不能用that
定语从句关系代词考点总结：1.在限制性定语从句中，如果先行词是人，用wh不会错。2.在限制性定语从句中，如果先行词是物，用that不会错。3.在非限制性定语从句中，先行词是人用wh，先行词是物用which。4. ne f the n（s）后面的谓语用复数 the nly ne f the n（s）谓语动词用单数
We have learned attributive clauses intrduced by relative prnuns in the last unit. Nw let’s learn attributive clauses intrduced by relative adverbs.
wh,whm,which,that,whse起着代词和连词的作用，在从句中充当主语，宾语或定语
when,where,why起着副词或介词短语和连词的作用，在从句中充当状语
关系词的作用：①代替前面的先行词在从句中充当一定的成分②把两个句子连接起来构成一个复合句
什么是状语？状语：说明地点、时间、原因、目的、结果、条件、方向、程度、方式和伴随状况等的句子成分叫做状语。除去五大基本概念和形容词（定语）剩下的成分就是状语。五大基本概念：主语、谓语、宾语、表语、宾补。
关系副词：副词是表示行为或状态特征的词，修饰动词、形容词或全局，表示时间，地点，程度，方式等概念。时间状语：when地点状语：where原因状语：why
The relative adverbials
relative adverbials关系副词
Where=at/n/in…which
Why=fr which
When=during/n/in…which
1. This is the huse where I lived 20 years ag. 2. I still remember the day when I first met him. 3. Can yu tell me the reasn why yu lied t me ?
1.观察先行词有什么特点？2.从句中缺少什么成分？
缺地点状语in the huse
缺时间状语n the day
缺原因状语fr this reasn
关系副词定语从句：1.前面必须有与之对应的先行词2.关系副词后面的从句是一个完整的句子。
① When 引导定语从句时，先行词为表示时间的名词，关系词在从句中作时间状语，可用“介词+ which” 来替换。
I’ll never frget the day when (n which) I jined the team .
I’ll never frget the day.
I jined the team n that day.
when引导的定语从句修饰表示时间的名词 time, hur, day, year, mment, ccasin 时刻，age年代，perid阶段, stage时期，interval 间隙等词 , 并在定语从句中作时间状语，相当于介词 (in/n/during)+which
I’ll never frget the stage in which(when) I studied in the schl.
我永远不会忘记我在学校学习的时期。
I'll never frget the day ______________ I first went t schl.
when /n which
There was a time _________________ he danced t the Little Apple everyday.
when/during which
There are many reasns why peple like traveling.
②关系副词why引导的定语从句表示原因(先行词一般是reasn), 在定语从句中作原因状语，相当于“fr which”。
fr which (=fr the reasns)
The minute yu think f giving up, think f the reasn why yu held n s lng.在你想要放弃的那一刻，想想为什么当初坚持走到了这里。
I dn’t knw the reasn ______________________________我不知道她为什么如此迷恋蔡徐坤。
I dn’t knw the reasn why / fr which she is s crazy abut Lu Han.我不知道她为什么如此迷恋蔡徐坤。
③ Where 引导定语从句时，先行词为表示地点的名词，关系词在从句中作地点状语，可用“介词+ which” 来替换。
The schl where(in which) my sn studies is near a park.
The schl is near a park.
My sn studies in this schl.
where引导的定语从句修饰表示地点的名词 place, rm, huse, area, rm, muntain抽象地点的名词如case, state, cnditin, pint, situatin等)的先行词并在定语从句中作地点状语，相当于介词 +which
The dictinary is the nly place where success cmes befre wrk.只有在字典里，“成功”才会出现在“工作”之前。where = in the place
Better keep yurself clean and bright. Yu are the windw thrugh which yu must see the wrld.我们透过自身这扇窗观望世界，因此，最好让它保持干净明亮。——萧伯纳
That is the place _____________ they met fr the first time.
where/in which
China is the nly cuntry__________________ wild pandas can be fund.
where/frm which
1．when引导定语从句when表示______,代替先行词并在定语从句中做_______，其先行词往往是表示时间的名词，如time, day, year, mnth, week等。2．where引导定语从句where表示_____, 代替先行词并在定语从句中做_______，其先行词往往是具体地点place, rm, muntain, airprt或抽象地点的名词如case, state, cnditin, pint, situatin等。3．why引导定语从句why表示_____, 代替先行词并在定语从句中做________，其先行词是表示理由的名词reasn。
in, at等介词+which
at, in, n, during等介词+which
wherewhenwhy
先行词为地点，一定用关系副词where吗？ 可以用that/which吗？
先行词为原因，一定用关系副词why吗？ 可以用that/which吗？
先行词为时间类，一定用关系副词when吗？ 可以用that/which吗？
4. 如何区分关系代词和关系副词引导的定语从句
★不能看到时间就用when，要看从句缺什么成分I’ll never frget the day ______ I lived in the muntains.I’ll never frget the day _______________ I spent in the muntains.
that/which/省略
★不能看到地点就用where, 要看从句缺什么成分This is the huse _______ he was brn.This is the huse _____________ was set up by his parents.
★不能看到reasn 就用why，要看从句缺什么成分This is the reasn _____ he was late.This is the reasn ____________he tld us fr his being late.
观察例句1. D yu remember the days ________ we chatted with each ther all night?2. D yu remember the days__________ we spent studying tgether in the classrm?3. I dn't knw the reasn ______ he didn't turn t his gd friend fr help yesterday.4. We wn't accept the reasn __________ yu have given.5. Can yu recgnize the huse ________ yu used t live with yur parents?6.Can yu recgnise the huse _________ Tm sld three years ag?
that/which
表示时间、地点及原因的名词作先行词时，先行词在定语从句中作状语时，应用关系副词；若先行词在定语从句中作主语或宾语时，则应用关系代词。 方法：分析从句句子成分
1. when相当于“ at/in/n/during等 + which” I remember the day ________________ I settled in China.2. where 相当于“ in/at/n等 + which”The huse ________________ Mark lived is nw a library. 3. why 相当于“fr + which” Is that the reasn ________ she suddenly changed her mind?
关系副词when，where，why引导定语从句时，也可用“介词+which”代替关系副词。
when (=n which)
where (=in which)
why (=fr which)
用when, where, why完成句子.
