含有介词的固定短语动词一般不分开,如lookafter、takecareof、lookat等。如:Isthisthewatchwhichheislookingfor?(不能说:Isthisthewatchforwhichheislooking?)【应用实践】(1)同义句转换。①IwillneverforgetthedaywhenIjoinedthearmy.→Iwillneverforgettheday_________Ijoinedthearmy.②Canyoutellmetheofficewhereheworks?→Canyoutellmetheoffice_________heworks?③Nobodyknowsthereasonwhyhehasnotturnedup.→Nobodyknowsthereason__________hehasnotturnedup.(2)一句多译。这就是我们曾经住过的那个房间。①Thisistheroom_________weoncelivedin.on

whichwhere在一些情况下,这个规则是不适用的。▶Iliketheway(that/inwhich)theteachergiveshislessons.我喜欢这位老师上课的方式。【探究总结】(1)关系副词和关系代词的选择依据先行词在定语从句中所作的成分。若是作状语,则用_________或______________;若是作主语、表语或宾语,则用_________。(2)用where引导定语从句,先行词不一定都表示地点。有一些先行词,如point、stage、position、case、policy、situation等,属于抽象的地点名词,需要用where引导定语从句。另外book、novel、scene、job、story、report、关系副词

介词+关系代词关系代词movie、painting、letter、activity等含有内容信息的名词有时也可以作为抽象地点名词来使用,意为“在……之中”,这时其后的定语从句也需要用where引导。(3)当先行词是way且在从句中作方式状语时,关系词可用inwhich或that,也可省略。【应用实践】(1)选择which、that、where、when、why填空。①Thevillage_________youvisitedlastweekismyfather’shometown.②Thevillage_____hegrewupisnotfarawayfromourtown.③Iwillneverforgetthedays______IvisitedBeijingwithmyfamily.④Iwillneverforgetthedays_________wespenttogether.⑤Wedon’tbelievethereason_________hegaveattheclassmeeting.⑥Wedon’tbelievethereason____hewaslateyesterday.that/whichwherewhenthat/whichthat/whichwhy(2)单句语法填空。①Tothosesuccessfuldeafdancers,dancingisanactivity_______sightmatt
