Relative adverbs (关系副词）vs Relative prnuns (关系代词）
缺6._____，选择7.____________
定语从句三步解体法：一、先找出主句；二、确定先行词三、判断关系词在从句中做的成分
that(主语/宾语/表语), which(主语/宾语),wh(主语/宾语), whm(宾语), whse(定语)，as(主语/宾语/表语)
that(主语、宾语), which(主语、宾语), whse(定语)
where (地点状语)
when (时间状语)
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
并非所有的表示“时间”和“地点”的先行词，后面的定语从句一定要用when和where引导。如果定语从句中缺少主语或宾语，就要用that或which引导。
This is the huse _____________ my father built last year.D yu still remember the days ___________ we spent in the cuntryside?
判断先行词在从句中的成分，用正确的关系词填空。
This is the reasn _______________ he went.The reasn _______________ he gave us was quite reasnable.
This is the place ____________ we visited last year.This is the place ____________ he wrks.
That was the time ____________ he arrived.D yu still remember the time ____________ we spent tgether?
which/that
that/which
why/fr which
关系副词when, where, why引导定语从句时, 关系副词也可用“介词+关系代词”代替。1. 关系代词的确定在“介词+关系代词”引导的定语从句中, 关系代词只能用which或whm, 先行词指物时, 用which; 先行词指人时, 用whm。
1. This is the camera with which he ften takes phts.
2. The ld wman with whm yu talked just nw is a famus artist.
He is the man in whm yu can believe.
(1)看介词与定语从句中动词或形容词的搭配。
He gave me sme bks with which I am nt very familiar.
(2)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)根据句子的意思而定。
The sldier, withut whm I wuldn't have survived the earthquake, retired last week.
The patient whm she is lking after is her father.
并非所有介词都可以放到关系代词前
有些“动词+介词”被视为一个固定的词组, 不可分割, 这时不能把介词置于关系代词前, 如：lk fr, lk after, pay attentin t, take care f , lk frward t, g thrugh等。
The patient after whm she is lking is her father.
1. The film star ___________ we talked a lt yesterday will give us a speech tmrrw.2. The West Lake _________ Hangzhu is famus in the wrld will be mre beautiful.3.
