1、inwhich,forwhich,onwhich,atwhich的不同用法这些都是定语从句里面，由which引导的定语从句，介词提前。inwhich可以翻译成在……里面forwhich可以翻译成为了……目的onwhich可以翻译成在……的上面，或具体时间的某一天atwhich可以翻译成在……里面或在……上面这些介词的使用除了意思上的区别，具体是要以which引导的从句而定的。例如：(1)Theschool(that/which)heoncestudiedinisveryfamous.=Theschoolinwhichheoncestudiedisveryfamous.

2、(2)TomorrowIwillbringhereamagazine(that/which)youaskedfor.=TomorrowIwillbringhereamagazineforwhichyouasked.(3)Ihaveadresserinmybedroom,whichtherearemanycosmeticson.=Ihaveadresserinmybedroomonwhichtherearemanycosmetics.(4)ThedumplingHousewhichheoftenhasdumplingsatisverypopular.=Thedumpli

3、ngHouseisverypopular,atwhichheoftenhasdumplings.当然这只是介词作为基本意思的用法，还有一些固定搭配，得具体情况具体分析。例如：Theplanemaybeseveralhourslate,inwhichcasethere’snopointinourwaiting.（固定搭配：inthecase)Thespeakerpausedtoexaminehisnotes,atwhichpointaloudcrashwasheard.（固定搭配：atthepoint)Tenyearsofhardworkchangedhergreatl

4、y,forwhichreasonhecouldhardlyrecognizeheratfirstsight.（固定搭配：forthereason）ThefilmatwhichIfellasleepwasveryboring.（Here"atwhich"isbasedon"fellasleepatthefilm"因为电影无聊而睡觉。）ThelittlecreatureinwhichscientistsareinterestedisknownasET.（这里"beinterestedin"是词组原因）Thisisthebookforwhichheislooking.（即等

5、于Thisisthebookwhichheislookingfor，这主要是因为lookfor这一短语）例题：1.Ican’tbelievethattherestaurant,______Ihaveeatensuchwonderfulmeal,isgoingtobeclosedown.A.whereB.atwhichC.aboutwhich【解答】选B。这个是非限制性定语从句，atwhich在功能上等于where，但就本题而言只能选atwhich。因为atwhichIhaveeatensuchwonderfulmeal是一个插入语，where固然可以引导，但是由于前面

6、有了一个逗号，就只能用atwhich了。“我难以相信我曾经在里面美美地吃过几顿大餐的饭店就要关张了。”非限制性定语从句主要就是先行词+逗号“，”+介词+which或者是先行词+逗号“，”+which，它和限定性定语从句的最显著区别一个是有逗号，一个是非限制定语从句总有which。2.Windpowerisanancientsourceofenergy______wemayreturninnearfuture.A.onwhichB.bywhichC.towhichD.fromwhich【解答】选C。returnto其实，应该来说，就是一个固定搭配了，解释为回归到，但是呢

7、，如果要说意思的话，也是说得通的，就是把句子换一换语序你就可以看出来了。“wemayreturntowindpowerinnearfuture.”也就是说，看到prep.+which这种形式，就可以直接把它扔到动词后面，然后在进行选择，看缺少哪个介词。3.Wehavegatherednearly100,000quilts,_____uptohalfhavegonetoflood-hitareas.A.withwhichB.inwhichC.forwhichD.ofwhich【解答】选D。这里的which指的是，nearly100,000quilts（
