如何选定介词的三原则：1.一先，是根据先行词与介词的搭配习惯.e.g.Thelittlegirlisreadingabook

therearemanypictures.2.二动，是根据从句中动词的习惯搭配.e.g.

Doyoulikethebook

shepaid$10?3.三意义，是根据定语从句的意义来确定介词e.g.Thisismypairofglasses,

Icannotseeclearly.

forwhichwithoutwhichinwhichwhichwhomwhose+n

as引导的定语从句

as引导限制性定语从句1.Suchbooksyouboughtareuseless.2.Thereissowarmahousewewanttolivein.3.Thisis

thesamedictionaryIusedyesterday.

归纳：如果先行词前有such，so，as，thesame等词修饰时,后面的定语从句常用as来引导。as充当从句的主语、宾语或者表语.

结构为：suchassoas

asasthesameas.asasas

as引导的非限制性定语从句

1.HecomesfromAmerica,

___iswellknowntous.2.___wasexpected,hefinishedthejobontime.

3.Hewaslateforthemeeting,_____madethebossveryangry.

归纳：as引导非限制性定语从句,as从句既可以

在主句前,也可以

放在主句后.从句动词经常是:see,know,mention,imagine,expect.as的含义为“正如,像….一样”.

which引导非限制性定语从句,但是which从句只能放在主句后，which常翻译做“这,这件事”强调结果和影响.

1.Shewasexcitedatthenews_____

hersonwasadmittedintoakeyuniversity.

2.Thenews_____hetoldusmadeusexcited.

总结：

定语从句是对先行词的修饰限定,而同位语从句是对前面名词内容的解释。

that引导定语从句充当成分，做宾语可以省去；

that引导同位语从句不做成分，只起连接作用，但也不能省去。
