 介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时

 从句常由介词+盐委决列高担关系代词引导

 (3)项济职肥话怎We’llgotohearthefamoussinger(whom/that/who)wehaveoftentalkedabout.

 =We’llgotohearthefa械零moussingeraboutwhomwehaveoftentalked.

 注意:

 1.含有介词的动词短语一般不拆开使用,如:lookfor,lookafter,ta盐跟注位甲存停道至kecareof等

 TThis选岁关送保蛋总干州束找isthewatchwhich/thatIamlookingfor.(T=正确)

 F练差务孩查火本ThisisthewatchforwhichIamlook型土办ing.(F=错误)

 2.若介词放在关系代词前,关系代词指人时用whom,不可用who或者that;指物时用which,不能用that;关系代词是所有格时用whose

 (1)Themanwithwhomyoutalkedismyfriend.(T)

 Themanwiththatyoutalkedismyfriend.(F)

 (2)TheplaneinwhichweflewtoCanadaisverycomfortable.(T)

 TheplaneinthatweflewintoCanadaisverycomfortable.(F)

 (2)Inthebaskettherearequitemanyapples,someofwhichhavegonebad.

 (3)Therearefortystudentsinourclassinall,mostofwhomarefrombigcities.

 关系代词

 关系代词(一般情况下)that可用who,whom和which在从句做主语,谓动词的宾语,但是不能做介词的宾语。

 which指物,在从句中作主语,谓语或宾语;

 who在从句中作主语;

 whom在从句中宾语;

 where在从句中修饰表地点的名词,做地点状语;

 when在从句中通常修饰表时间的名词,做时间状语;

 why在从句中做原因状语,先行词通常是"reason"

 有时why也可用for+which代替。

 例:Adoctorisapersonwholooksafterpeople'shealth.

 定语从句修饰先行词

 判断介词和关系代词

 方法一:用关系代词,还是关系副词完全取决于从句中的谓语动词。不及物动词后面无宾语,就必须要求用关系副词或者是介词加关系代词;而及物动词后接宾语,则要求用关系代词。例如:

 ThisisthemountainvillagewhereIstayedlastyear.

 I'llneverforgetthedayswhenIworkedtogetherwithyou.

 判断改错(注:先显示题,再显示答案,横线;用不同的颜色表示出。)

 (错)ThisisthemountainvillagewhereIvisitedlastyear.

 (错)IwillneverforgetthedayswhenIspentinthecountryside.

 (对)Thisisthemountainvillage(which)Ivisitedlastyear.

 (对)I'llneverforgetthedays(which)Ispentinthecountryside.

 习惯上总把表地点或时间的名词与关系副词where,when联系在一起。此两题错在关系词的误用上。

 方法二:准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词。例1.Isthismuseum___youvisitedafewdaysago?

 A.whereB.thatC.onwhichD.theone

 例2.Isthisthemuseum____theexhibitionwasheld?

 A.whereB.thatC.onwhichD.theone答案:

 例1D,例2A

 例1变为肯定句:Thismuseumis___youvisitedafewdaysago.例2变为肯定句:Thisisthemuseum___theexhibitionwasheld.

 在句1中,is后应跟表语,只有theone可以,而后面的youvisitedafewdaysago则做one的定语从句。

 而句2中,主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因inthemuseum词组,可用介词in+which引导地点状语。而此题中,介词on用的不对,所以选A。

 关系词的选择依据在从句中所做的成分,先行词在从句中做主、定、宾语时,选择关系代词(who,whom,that,which,whose);

 先行词在从句中做状语时,应选择关系副词(where地点状语,when时间状语,why原因状语)。
