1、从since when说起,浅谈几个特殊的定语从句 定语从句是高考的热点之一,在每年的高考英语试题中,几乎所以省份都会考查一处定语从句。而且,最近几年还考到了比较特殊的用法。请看两道山东卷中的试题:【典型例题】1.Hewaseducatedatalocalgrammarschool,______hewentontoCambridge.(2005年山东卷)A.fromwhich B.afterthat C.afterwhich D.fromthis2.Thebookwaswrittenin1946,____
2、__theeducationsystemhaswitnessedgreatchanges.(2007年山东卷)A.when B.duringwhich C.sincethen D.sincewhen【典例分析】1.句意:他在当地一所文法学校上学,之后他便去了剑桥。根据句意可排除A、D两项;afterthat意为“然后,之后”,但不能引导一个定语从句,因此B项也被排除;afterwhich相当于andafterthat,不但符合语境,而且能引导定语从句,故答案为C。2.句意:该书写于1946年,从那以后
3、教育制度已经历了巨大变化。根据从句中的现在完成时态和句意,我们可排除A、B两项;短语sincethen意为“从那以后”,但不能引导一个定语从句,因此也排除了C项;故此处应选D项,sincewhen相当于andsincethen,它能引导一个定语从句。【同类例句】除了上述例题外,我们还回见到下面的例子:1.Athome,heneverseemstohavetimeuntilafter10:30pm,bywhichtimehischildrenhavegonetobed.=Athome,heneverseemstohavetimeuntilafter10:30pm,andbythattimehi
4、schildrenhavegonetobed.在家里,他好像十点半之后才有空,到那时孩子们已上床睡觉了。2.Wewerenext-doorneighborsforthreeyears,duringwhichtimewemetonlytwice.=Wewerenext-doorneighborsforthreeyears,andduringthis/thattimewemetonlytwice.我们做了三年隔壁邻居,在此期间我们只见过两次面。3.Itoccurredtohimthatitwouldsavealotoftroubletodestroytheadvertisement,inwhic
5、hcase,hewouldhavetoexplaintoPeter.=Itoccurredtohimthatitwouldsavealotoftroubletodestroytheadvertisement,butinthatcase,hewouldhavetoexplaintoPeter. 他曾想到过,撤销广告会避免很多麻烦;但是如果那样的话,他必须向皮特做出解释。4.Iwastoldmyworkwasunsatisfactory,atwhichpointIsubmittedmyresignation.=Iwastoldmyworkwasunsatisfactory,andat
6、this/thatpointIsubmittedmyresignation. 被告知我的工作不能令人满意,闻讯后我便递交了辞呈。5.Heisstudyingeconomics,whichknowledgeisprettyimportanttoday.=Heisstudyingeconomics,andthisknowledgeisprettyimportanttoday. 他在学习经济学,这门知识在当今非常重要。6.Hestoodbythewindow,fromwherehecouldseewhatwashappeningoutside.=Hestoodbythewi
7、ndow,andfromtherehecouldseewhatwashappeningoutside. 他站在窗子旁边,从那儿他能看到外面发生的一切。【小结点拨】根据上面的例句,我们不妨做出如下总结:①带有this,that的短语,引导定语从句时,要将this,that变为which;②带有here,there的短语,引导定语从句时,要将here,there变为where;③带有then,now的
