“介詞+/whom”引的語句“介詞+關(guān)代”導(dǎo)的定語從句是定語從句一種介詞前置的定語句句型詞關(guān)系代詞之間存在一種介賓關(guān)系。當(dāng)關(guān)系代詞在定語從句中作介詞賓語時(shí)，把介詞置于關(guān)系代詞前，即演變介詞+關(guān)系代句型。例如：Thewho/whom/thatyouspoketoisateacher.towhomisteacher.一、基本構(gòu)成介詞+關(guān)代結(jié)構(gòu)引導(dǎo)的定語從句中關(guān)代只用which指）或人)，即介+which/whom。（1Thetoisa（2Thecityinlivesisaway.（3Thelittlegirlisabook,inwhichtherearemany注：介放關(guān)代的面，在詞的系詞能省。在限制性定語句，當(dāng)介詞于定語從的謂語動(dòng)詞后時(shí)，可指物；指人）作介詞的賓語.此處關(guān)系代詞可以省略，特別是在口語中。如：（1))toisateacher.（2Thecity）livesinisfar注通介放定從中詞，可放關(guān)代前，但些殊詞語配能分介只放動(dòng)后如lookcareof,to,等。Thisispen/whicharelookingfor.ThepatientwhomsheisafterherTheshouldwrittenontheblackboard.Therefiftymusttake練：Arewithwhomyouisfriend.man(who/that)youtalkedwithisfriend.withwho/thatyoutalkedismyfriend.planeinwhichflewtoCanadaverycomfortable.planeinflewtoverycomfortable.二、關(guān)系副詞when，，why可用介詞＋which來代替。關(guān)系副詞實(shí)上是介詞＋先行詞。

其表時(shí)的詞如in，等）+whichWhere=表地的詞如，at,on,under等；Why=表原的詞如for+which(1)當(dāng)先行詞表示時(shí)間定從句中缺少時(shí)間狀語時(shí)通常用關(guān)系副詞引，此時(shí)也可選用表示時(shí)間的介詞＋which來替關(guān)系副詞whenIrememberwhenIhere.(on=when)(2)當(dāng)先行詞表示地點(diǎn)，定語從句缺少地點(diǎn)狀語時(shí)，通常用關(guān)系副詞where引導(dǎo)，此時(shí)也可選用表示地點(diǎn)的介詞＋which來替關(guān)系副詞whereThisiswhereIlivedlast(thewhere)(3)當(dāng)先行詞為reason，定語從句中缺少表示原因語時(shí)，通常用關(guān)系副詞why引，此時(shí)也可以用forwhich代替關(guān)系副詞why。Therewhypeopleliketraveling.reasons=why)三、關(guān)系代詞前介詞選擇三原則：一先，二動(dòng)，三意義（重中之重）一，根據(jù)定語從句介詞先詞搭配關(guān)系選擇。IneveronIcametothisthe二，根據(jù)定語從句謂語詞介的配關(guān)系選擇。ThisisonIspent(spendmoneyon三義即根據(jù)定語從句意義確定介詞。Thisispairwhich__Icannotsee例：“介+系詞的形式示Doyou__________learnedlot?Hetheforwashingwindows,hadn'tcleanedThe_________peopleagoodisthehill.注：介關(guān)代）介詞后面的關(guān)系代詞不能省略。）前不能有介詞。）某些在從句中充當(dāng)時(shí)間，地點(diǎn)或原因狀語的"詞+關(guān)詞"構(gòu)可以同關(guān)系副詞when,where和互。練
