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___________;其中________________________________为关系代词。
which, that, wh, whm, whse, as
定语从句： 在复合句中修饰名词或代词，在句子中起定语作用的从句
Bbby is a by wh is very fat..
先行词: 被修饰的名词或代词关系词：1. 连接从句；2. 替代先行词；3. 在从句中充当成分
He is the man in whm yu can believe.
2. “二动”看定语从句中动词或形容词与介词的搭配。
He gave me sme bks with which I am nt very familiar.
1. “一先”看介词与先行词搭配。
This is ur classrm in which there is a teacher’s desk.The farm n which my father wrks is far frm the twn.
3. “三意义”根据句意而定。
The sldier, withut whm I wuldn't have suvived the earthquake, retired last week.
Task1：介词+which, 介词如何选择?
“一先”，即根据先行词的习惯搭配或意义来确定介词。“二动”，即根据定语从句中的谓语动词的习惯搭配来确定介词。“三意义”，即根据定语从句所表达的意义来确定介词。
技巧点拨:介词 + 关系代词引导定语从句时,如先行词是人, 关系代词只能为whm. 如先行词是物, 关系代词只能为which.
用介词 ＋ 关系代词填空1. Wh is the persn _______ _______ yu just shk hands?2. China is a pwerful cuntry, _______ _______ we are prud.3. This is the tree _______ _______ we used t play games.4. This is my glasses, _______ _______ I can’t see clearly.5. D yu remember the day _______ _______ yu jined ur club?
with whm
withut which
under which
f which
n which
Task2：探究when/where/why的用法
1.关系副词--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, 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 date when(n which ) my baby by was brn.They stayed with me three weeks, when (during which) they drank all the wine I had.
★不能看到时间就用when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
2.关系副词--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还可用在表示抽象意义的地点名词后，如situatin, stage, pint, case, psitin, cnditin等,意思是“到了某种地步，在某种境况中” I have cme t the pint where(at which) I can't stand him.我已经到了无法容忍他的地步。He's gt int the situatin where(in which) he is in debt.他已经陷人负债累累的境地。At last he gt the psitin (that/which) he had been dreaming f. 他最终得到了他梦寐以求的那个职位。
★不能看到地点就用where, 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.
3.关系副词--Why引导定语从句时，先行词通常为reasn，关系词在从句中作原因状语，可用“fr+ which” 来替换。
D yu knw the reasn why (fr which) he is s upset?
D yu knw the reasn.
He is s upset.
★不能看到reasn, 就用why.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.
Task3：关系代词 VS. 关系副词
