1、as的用法:(as引导定语从句,在定语从句中作主语、宾语、表语)(1)如为限制性的,多用于thesame…as;thesameas;such…as…;asmany/muchas;so…as等结构中。如:1.Ihavethesamebookasyou(have).我有一本和你的一样的书。Herattitudetohimwasquitethesameasithadalwaysbeen.(关系代词as和指示代词same连用,在从句中用作表语,先行词是same.)2.---Whydidn'tyoumentionthatinfaceofthepolicejustnow?---Ithou

3、issobigastoneasnoonecanlift.(定语从句)Hereissobigastonethatnoonecanliftit.(结果状语从句)(2)如为非限制性的,多单独引导一个定语从句,这种定语从句可置于句首,句中或句尾,译为"正如,这一点"。(动词常为know,see,expect,pointout,etc.)1.Asweallknow,smokingisharmfultoone'shealth.(as作宾语)=Asisknowntoall,smokingisharmfultoone'shealth.(as作主语)=It'sknowntoallthatsmo
4、kingisharmfultoone'shealth.或:Smokingisharmfultoone'shealth,asweallknow.(as作宾语)或:Smoking,asweallknow,isharmfultoone'health.2.Hewasaforeigner,asIknewfromhisaccent.(宾语,先行词是前面整个句子)当先行词被thesame所修饰时,关系词既可以用as,也可以用that。在表示具体事物时,有时两者有一定的区别。一般说来,表示同一种类多用as,表示同一事物多用that。如:ThisisthesameinstrumentthatI
5、usedyesterday.这就是我昨天用过的那台仪器。ThisisthesameinstrumentasIusedyesterday.这台仪器跟我昨天用过的那台一样。在抽象概念上,同种类和同一事物是没有绝对区别的,所以两个词可换用:Ihavethesameopinionas/thatyouhave.这里要注意的是:(1)使用as时,它引导的定语从句中的动词可以省略,但使用that时,定语从句中的动词不可省略。如:Womenreceivedthesamepayasmen.Womenreceivedthesamepaythatmenreceived.(2)在“thesame…t
6、hat”结构中,that只是用来加强语气,强调“相同”。that可以省去而不改变句子原意,甚至连名词前的same也可以省去。如:ThisisthesameinstrumentthatIusedyesterday.=ThisisthesameinstrumentIusedyesterday.=ThisistheinstrumentIusedyesterday.但在“thesame…as”结构中,same和as都不能省略。(3)当“thesame…that”结构中的that作为关系副词用时,不可以直接与as互换。如:HelivesinthesamebuildingthatIliv
7、e.(inthesamebuilding)=Helivesinthesamebuildingas/thatIlivein.(thesamebuilding)Shallwemeetatthesameplacethatwelastmet?(atthesameplace)=Shallwemeetatthesameplacethat/aswelastmetat?(thesameplace)7.当先行词前有such,so,as时,关系词应当用as。如:Awisemanseldomtalksaboutsuchthi
