二、关系词的用法：

（一）关系代词的用法：

1．

Heistheman livesnextdoor.

Thetrain hasjustleftisforShenzhen.2．

Theman wehavejustseenisafamouswriter.

Whereisthebook Iboughtlastweek?

注：

3．

Heistheman carwasstolenlastweek.

Itwasameeting importanceIdidnotrealizeatthattime.

Theycametoahouse backwallhadbrokendown..(= )

He’swrittenabookthename I’vecompletelyforgotten.(= )

4．作表语只用that，它既可以指人，也可以指物，但时常省略。如：

Heisnolongerthemanthatheusedtobe.

Thisisnolongerthedirtyplace(that)itusedtobe.

（二）关系副词的用法：

when： time,day,morning,night,week,year

Istillrememberthetime Ifirstbecameacollegestudent.Doyouknowthedate Lincolnwasborn?

Where place,spot,street,house,room,city,town,country

Thisisthehotel theyarestaying.

Iforgetthehouse theSmithslived.

why

Thatisthereason heisleavingsosoon.

(三)使用关系副词应注意下列几点：

这三个关系副词在意义上都相当于一定的介词+which结构：

when=on(in,at,during…)+which;where=in(at,on…)+which;

why=forwhich.如：

IwasinBeijingonthedaywhen(=onwhich)hearrived.Theofficewhere(=inwhich)heworksisonthethirdfloor.Thisisthechiefreasonwhy(=forwhich)wedidit.

当先行词是表时间的time,day等和表地点的place,house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when

或where，试比较：

I’llneverforgettheday myhometownwasliberated.

I’llneverforgetthedays wespenttogetherlastsummer.Hisfatherworksinafactory radiopartsaremade.

Hisfatherworksinafactory 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
