一、基本概念：
定语从句

关系代词有：thatwhowhomwhosewhich在从句中充当：关系副词有：whe
wherewhy在从句充当：先行词：
定语从句中引关系词的作用：
二、关系词的用法：
（一）关系代词的用法：
1．Heisthema

lives
extdoor
Thetrai

hasjustleftisforShe
zhe

2．Thema
________wehavejustsee
isafamouswriter
Whereisthebook___________Iboughtlastweek（二）关系副词的用法：
1．Istillrememberthetime________Ifirstbecameacollegestude
t
Doyouk
owthedate__________Li
col
wasbor
三使用关系副词应注意下列几点：1．这三个关系副词在意义上都相当于一定的介词which结构：
whe
o
i
atduri
g…which
wherei
ato
…whichwhyforwhich如：
Iwasi
Beiji
go
thedaywhe
o
whichhearrived
Theofficewherei
whichheworksiso
thethirdfloor
Thisisthechiefreaso
whyforwhichwedidit2．当先行词是表时间的timeday等和表地点的placehouse等时，一定要注意分析从句的结构，如果缺少主语或宾语时，关系词应该用which或that缺少时间状语或地点状语时，才能用whe
或where，试比较：
I’ll
everforgettheday_________myhometow
wasliberated
fI’ll
everforgetthedays____________wespe
ttogetherlastsummerHisfatherworksi
afactory____________radiopartsaremadeHisfatherworksi
afactory______________makesradioparts三．限制性定语从句与非限制性定语从句1．限制性定语从句ThisisthetelegramwhichhereferstoIstherea
ythi
gthatIca
doforyou2．非限制性定语从句This
otewasleftbyTomwhowashereamome
tagoAsaboyhewasalwaysmaki
gthi
gsmostofwhichwereelectric引导非限制性定语从句的关系词有whowhomwhosewhichwhe
和where不可以用that和why。注意：ItoldthestorytoJoh
wholaterdidittohisbrotherItoldthestorytoJoh
a
dhelatertoldittohisbrotherYesterdayIhappe
edtoseeJoh
whowaseagertohaveatalkwithyouYesterdayIhappe
edtoseeJoh
a
dhewaseagertohaveatalkwithyou4．先行词为整个主句或是主句中的一个部分，用which或as来引导。如：Hepassedtheexamwhichashehopedhewould注：（1）as引导的从句可以放在主句之前、中、后，而which引导的从句只能放在主句之后。TheyarehollowwhichmakesthemverylightAsisk
