  。正确使用that和which1、that指物,有时也可以指人,which指物,不能指人。Which可以引导非限制性定语从句,也可以放在介词后面,that则不能。例如:Whoisthemanthatisreadingthenewspaper?(正)Whoisthemanwhichisreadingthenewspaper?(误)Theroominwhichshelivesisalargeone。
  (正)Theroominthatshelivesisalargeone。(误)2、先行词前面有形容词最高级,序数词next,last,very,any,little,no等修饰时,用that不用which引导定语从句。
  例如:ThisisthebestfilmthatIhaveseen。(正)ThisisthebestfilmwhichIhaveseen。(误)3、先行词是all,much,little,none等时,用that而不用which引导定语从句。
  例如:That’sallthatIwanttosay。(正)That’sallwhichwanttosay。(误)4、先行词是不定代词something,anything,anything,everything时,一般用that而不用which引导定语从句。
  例如:Isthereanythingthatyouwantinthisshop?(正)Isthereanythingwhichyouwantinthisshop?(误)注:当something表示具体的事物,重要的东西,重要的人物等确定意义时,它是名词,关系代词用that或which均可。
  例如:Therewasthemysterioussomethingwhich/thattheyhadworkedsoh 、先行词是人和物时,要用that而不用which/who引导定语从句。例如:Hetalkedaboutsomewritersandbooksthatwereunknowntousall。
  (正)Hetalkedaboutsomewritersandbookswhich/whowereunknowntousall。(误)6、先行词本身是that时,一般用which引导定语从句。例如:Thepredicateisthatwhichissaidofthesubject。
  7、在who开头的疑问句中,若还要用关系代词引导定语从句时,用that引导定语从句。例如:Whoisthegirlthatissinginginthehall?8、当关系词后面有插入语时用which引导定语从句。
  例如:HereistheEnglishgrammarbookwhich,asIhavetoldyou,willhelptoimproveyourEnglish。IV。定语从句要用关系词引导。例如:Ihavethreefriends,noneofwhomcanspeakFrench。
  (正)Ihavethreefriends,noneofthemcanspeakFrench。(误)注:若把逗号“,”改为分号“;”误句也就变为正确的句子了。V。先行词受such,thesame修饰时,通常用as引导定语从句。
  例如:ThisisnotsuchabookasIwant。ThisisthesamebookasIwant。试比较:thesame…as与thesame…thatThisisthesameknifeasIlost。
  这把刀跟我丢的是一模一样的。(两把刀)ThisisthesameknifethatIlost。这把刀就是我丢的。(一把刀)。收起
