aswhich指代引导从句只能指代整个主句的内容引导从句既可指代整个主句的内容，也可指代主句的一部分位置可位于主句之前，之中或之后引导从句不能置于主句之前意义asisknowntoall众所周知ashasbeensaidbefore

如前所说asisoftenthecase

情况常常如此ashasbeenpointedout

正如指出asoftenhappens

这情况常发生

翻译成：这，那功能连接上下文，表达说话人的观点、看法，并指出主句内容的根据或出处等引导的从句在意义上相当于一个并列句1.________isannouncedintoday'snewspaper,wemustimproveourstyleofwork.2.Taiwan,_______weallknow,belongstoChina.3.Itrainedhardyesterday,whichpreventedmefromgoingtothepark.4.Untilnow,wehaveraised50,000poundsforthepoorchildren,_______isquiteunexpected.5.Thereisnosimpleanswer,______isoftenthecaseinscience.6.ThepresidentsayshehasapassionforChina,______heremembersstartingasearlyashischildhood.AsAswhichaswhich【典例4】完成句子(1)我们已经找到了像他们工厂里用的那种材料。Wehavefoundsuchmaterials____________________________．(2)我和他有同样的书。 Ihavethesamebook_________．(3)太阳可以使地球变得温暖,这对我们很重要。ThesunheatstheEarth,_____________________________．(4)正如我们预料的那样,她再婚了。 Shemarriedagain,______________________．asareusedintheirfactoryashehaswhichisveryimportanttousasweexpected介词＋关系代词31.“介词＋关系代词”既能引导限制性定语从句,又能引导非限制性定语从句。先行词指物时,关系代词用which；先行词指人时,关系代词用whom；关系代词whose与所修饰的名词也可同时放在介词之后。Eg.Thereare40studentsinourclass,mostofwhom

likeEnglishEg.Chinaisalargecountryinwhich

manydifferentdialectsarespoken.中国是一个讲许多不同方言的大国。2.“介词＋关系代词”结构中介词的确定（1）根据定语从句中动词、形容词所需要的某种习惯搭配来确定。（2）根据与先行词搭配的具体含义而定。（3）根据所表达的意思来确定。1.Inthedarkstreettherewasn’tasingleperson_____shecouldturnforhelp.

A.thatB.whoC.fromwhomD.towhom

介词to和定语从句中的turn构成固定搭配turntosb.forhelp。D2.Thechildren,______hadplayedthewholedaylong,werewornout.A.allofwhatB.allofwhichC.allofthemD.allofwhom3.Iwasgiventhreebooksoncooking,thefirst_______Ireallyenjoyed.A.ofthat
