定语从句系列只能用关系代词that引导的九种情况

定语从句系列只能用关系代词that引导的九种情况人生底色在于语文在学习定语从句的过程中，同学们需要注意以下九种情况，只能使用关系代词that引导定语从句。1.当先行词为不定代词，如all、much、none、something、nothing、everything、theone、few、little、many、anything等。例如：我们应该做一切有益于人民的事情，Weshoulddoallthatisusefultothepeople。2.当先行词被不定代词修饰，如only、any、few、little、no、all、many、much等。例如：我已经看完了所有从图书馆借来的书，IhavefinishedreadingallthebooksthatIborrowedfromthelibrary。3.当先行词被序数词、形容词最高级以及theonly、thevery、thenext、thelast等修饰时。例如：这是我在这家书店买的第一本书，ThisisthefirstbookthatIboughtintheshop。ThisistheverybookthatIwaslookingfor.（先行词是book，被thevery修饰，用that引导定语从句，强调“正是我要找的那本书”）3、先行词既指人又指物时ThepersonandthecarthatIsawwerebothgone.（先行词是person和car，都指人和物，用that引导定语从句，修饰两者都已经不见了）4、关系代词在限制性定语从句中作表语，并带有比较的含义时ThemovieisnotasgoodaswhatIexpectedittobe.（关系代词what作表语，带有比较含义，修饰movie）5、句子的前一部分已经出现了which，为避免重复，句子的后面部分通常不再用which而用that来引导限制性定语从句Thebook,whichIborrowedfromthelibrary,isveryinteresting.（先行词是book，前面已经用了which引导从句，后面用that来引导修饰book的从句）6、当主句是以who,which引起的特殊疑问句时，关系代词通常只用thatWhoisthepersonthatyouaretalkingto?（先行词是person，用that引导修饰从句）7、在therebe句型中，只能用thatThereisadogthatisbarkingoutside.（先行词是dog，用that引导修饰从句）Sheistheonlygirlthathaswonaprize,emphasizingthatsheistheonlyoneamongthegirlswhohasachievedthis.TheplacethattheyfirstvisitedwastheBigBen,emphasizingthatitwasthefirstplacetheywentto.Allthatcouldbedonehasbeendone,emphasizingthateverythingpossiblehasbeendone.ThereislittlethatIcandoforyou,emphasizingthatthereisnotmuchthatcanbedonetohelp.Whoisthemanthatisstandingthere?ThisisalimitingconstructioninEnglishtoavoidrepetition,eventhough"who"referstoapersonand"that"referstoanobject.Whenreferring
