译成并列句1二者差异比较限制定语从句紧跟先行词,同先行词之间一般不加逗号,仅修饰先行词,可以由关系代词关系副词或that来引导。非限制性定语从句仅作补充或说明,用逗号与主句隔开,既可修饰先行词,又可修饰整个主句,不可用that引导。hehasabrotherwhoisaphysicist。hehasabrother,whoisaphysicist。(只有一个)hereturnedallthebookswhicharewritteninenglish。hereturnedallthebooks,whicharewritteninenglish。iwillwearnoclotheswhichwillbeoutofordinary。iwillwearnoclothes,whichwillbeoutofordinary。themanwholivesnextdoorisadoctor。mysister,wholivesnextdoor,isadoctor。i’msureiknowthepersonwhoservedme。tom,whoservedus,istheowneroftherestaurant。astudentwhostudieshardwillmakegoodprogress。thestudent,wholivesfarfromschool,istheleaderoftheirfootballmatch。(六)关系代词that和which的区别lt;1gt;只能用that的情况(1)如果先行词是all,much,anything,something,nothing,everything,little,none,few。等不定代词,关系代词一般只用that,不用which。例如:allthepeoplethatarepresentburstintotears。everythingthatwesawwasinteresting。i’minterestedineverythingthatidon’tknow。allthatisneededisasupplyofoil。(2)如果先等词被all,littlenoneany,only,few,much,no,some,very等词修饰,关系代词常用that,不用which。例如:ireadallthebooksthatyougavetome。thisistheonlymoneythatihaveinmypocket。allthemoneythatwascollectedwasgiventothehopeproject。(3)如果先行词被序数词、形容词最高级修饰或者先行词是最高级时,关系代词常用that,不用which。thisisthefirstbookthatwaswritteninenglish。thisisthelastfactorythativisited。thisisthebestfilmthatihaveeverseen。thisisthefunniestthingthatieverheard。(4)如果先等词被theonly,thevery,thesame,thelast修饰,关系代词常用that,不用which。thisistheonlybookthatireallylike。hewastheonlypersonintheofficethatwasinvitedtotheball。(5)先行词有两个,一个指人,一个指物,关系代词应该用that。而不用who,which。例如:theboyandthedogthatareinthepictureareverylovely。hetalkedabouttheteachersandschoolsthathehadvisited。(6)who,which开头的特殊疑问句中,关系代词用that。whoisthepersonthatisstandingthere?whichofusthatknowsenglishdoesn’tknowthis?whichofthenoveldoyoulikebest?(7)关系代词作表语时,关系代词用that。ittookusmanyyearstomakethecitythatitistoday。heisnotthemanthatheusedtobe。chinaisn’tthecountryitusedtobe。(8)先行词是奇数词或是序数词时,关系代词用that。yesterdayicaughttwofish。nowyoucanseethetwothatarestillaliveinthebasinofwater。(9)当主句therebe开头时,关系代词要用that引导的定语从句修饰该句型的主语。therearefourdesksinthemiddleoftheofficethatareusedfortheteachers。(10)当先行词是tobe后面的表语时关系代词用that。thisisthedictionarythatwasboughtinthebookstoreyesterday。lt;2gt;只能用which的情况1)非限制性定语从句中,不能用关系代词that,作宾语用的关系代词也不能省略。如:thereareaboutsevenmillionpeopletakingpartintheelection,mostofwhom、arewelleducated。beijing,whichischina’scapital,isrichinculture。2)thosethat名词后的定语从句用which引导。不能用关系代词that。thatpenwhichhetookismine。ashopshouldkeepthosegoodswhichsellswell。3)介词后只用whichthisistheroominwhichhelived。idon’tknowthemantowhomyoutalked。thechaironwhichheissittingismadeofwood。(4)which还有一种特殊用法,它可以引导从句修饰前面的整个主句,代替主句所表示的整体概念或部分概念。在这种从句中,which可以作主语,也可以作宾语或表语,不用that。。例如:hesucceededinthecompetition,whichmadehisparentsveryhappy。(5)先行词是that时,关系代词要用which。what’sthatwhichflashedintheskyjustnow?(6)关系代词后面有插入语时,益用关系代词which。hereistheenglishgrammarbookwhich,asihavetoldyou,willhelptoimproveyourenglish。lt;3gt;只用who,whom。而不用that的情况(1)如果先行词是anyone,anybody,everyone,everybody,someone,somebody,those,ones等时,关系代词应该用who或whom,不用which。that。例如:isthereanyoneherewhowillgowithyou?peoplealllikethosewhohavegoodmanners。(2)当先行词是指人的集合名词时,如果作这个名词着眼于集体的整体,关系代词用which;若是指集体中的各个成员,则用who。mr。smithcametovisitmyfamily,whowerewatchingtvthen。ourclass,whichisaverygoodone,waspraisedagainatthemeeting。(3)当先行词有较长的后置定语或者在被分割的定语从句中,宜用关系代词whopro。wangiscomingsoonwhowillgiveusatalkonhowtolearnenglish。(4)当先行词用body或one构成的复合不定代词时,关系代词用whowe’dbetternotbelieveinanyonewhowedon’tknow。(5)当先行词是一个限定性的表示人的特定名词时,常用whotheauntunclewhocametoseeuslastweekismybrother’ssister。(七)介词关系代词是一个普遍使用的结构(1)介词关系代词可以引导限制性定语从句,也可以引导非限制性定语从句。介词关系代词结构中的介词可以是in,on,about,from,for,with,toat,of,without等,关系代词只可用whom或which,不可用that。其中whom代表人,which代表物whoisthecomradewithwhomyoushookhands?heworksinafactory,infrontofwhichthereisarivergivemethebookthecoverofwhichisred(thecoverofwhichwhosecover)heisthemanwhosefatherisateacher。heisthemanthefatherofwhomisateacher。thisistheneighborhoodfromwhomiborrowedthebicycle。(2)fromwhere为介词关系副词结构,但也可以引导定语从句(不常用)。例如:westoodatthetopofthehill,fromwherewecanseethetown。。(3)关系代词前的介词如何确定?a。依据定语从句中动词的某种习惯搭配mr。smithboughtanewhouseonwhichhespentallhismoney。b。依据先行词的某种习惯搭配确定therewasnowayinwhichitcouldbeboughtbacktotheearth。(inthisway)c。根据所表达的意思确定thegaswithwhichdoctorscansavethepatientsiscalledoxygen。thegaswithoutwhichwecannotliveiscalledoxygen。(4)注意关系代词的位置介词在关系代词前时,只能用which和whom不能用that代替,也不可省略;介词在句尾时,关系代词可which,that,whom,who,都行,而且还可以省略。thisisthedrawerinwhichiputmyletters。thisisthedrawer(whichthat)iputmylettersin。haveyouseenthepenwithwhichiwrotelettersthismorning?haveyouseenthepen(whichthat)iwroteletterswiththismorning?所以一个句子有时有多种用法如:那就是他工作的大学thisisthecollegeatwhichheworks。thisisthecollegethatwhichheworksat。thisisthecollegewhereheworks。但像listento,lookat,dependon,payattentionto,takecareof等固定短语动词,在定语从句中一般不宜将介词与动词分开。例如:thisistheboywhomshehastakencareof。thisisthebookwhichthatiamlookingfor。thisisthegirlihavebeenlookingforthewholeafternoon。(八)whose引导从句的意义1)指人ofwhom表示所修饰的某(些)人的用做所修饰的先行词的所有格。achildwhoseparentsaredeadiscalledanorphan。2)指物ofwhich表所修饰的某物的iliveintheroomwhosewindowfacessouth。iliveintheroom,thewindowofwhichfacessouth(whose从句可以用ofwhich从句代替)(九)as与which是有区别的a)相同之处:都可以用来引导非限制性定语从句,指代前面的主句所表达的内容。which可做宾语或表语hefailedoncemoreinthematch,whichwasagreatpity。hesucceededinthecomposition,whichmadehisparentsveryhappy。b)区别:1)as引导的非限制性定语从句位置较灵活,可以位于主句前面中间或后面,一般用逗号与主句隔开,但which所引导的非限制性定语从句只能放在主句之后。例如:1)asweallknow,galileo’stheoryoffallingobjectsisright。galileo’stheoryoffallingobjects,asweallknow,isrightgalileo’stheoryoffallingobjectsisright,asweallknow。2)hewasthrownintoprison,whichgotroundthroughoutourvillage3)asisexpected,theenglandteamwonthefootballmatch。4)theearthrunsaroundthesun,asisknownbyeveryone。5)hewaslateagain,whichmademeunhappy6)asyouknow,heisgoodatenglish。2。)as有如、正如、像、正像的含义,which没有。后面的谓语动词多是see,know,expect,say,mention,report等。bobdidanexcellentjob,aswehadexpected。ourteamwonthegame,whichmadeushappy。asisknowntoall,taiwanispartofchina。wearefacingthesameproblemsaswedidyearsago。wearefacingtheproblemswhichwefacedyearsago。wehopetogetsuchatoolasheisusing。wehopetogetthetoolwhichheisusing。3。)as在引导限制性定语从句多与such或thesame连用,可以代替先行词是人或物的名词。thesameassuch。asthisisthesamestoryashetoldme。ihopetogetsuchabookasheisusing4)。as也可单独使用,引导非限制性定语从句,作用相当于which。可代表一个句子。例如:theelephant’snoseislikeasnake,asanybodycansee。5)。as做主语时,其后必跟系动词,而which无此限制themeetingwasputoff,aswaswhatwewanted。 hewasmurdered,asseemedtrue。6)as引导从句时,从句语义必须和主句一致shewasmarriedagain,whichwasunexpectedshewasmarriedagain,aswasunexpected77)thesameas与thesame。。that的区别:前者修饰的是原物同样的而后者修饰的就是先行词thisisthesamewatchasilost。这和我丢的那一只手表是一样的。thisisthedamewatchthatilost。着就是我丢的那一只手表。(十)什么时候that可以省略?1)引导同位语从句,主语从句,表语从句不能省略,且不做成分。thenamewhitewatercomesfromthefactthatthewaterinthesestreamsandriverslookswhitewhenitmovesquickly。it’sknowntoallthatlighttravelsinstraightlines。(that置后可一省略)thereasonforhisabsencewasthathewasill。(有时可省,一般不省)2)宾语从句中可以省略idon’tthink(that)youareright。3)that只有在定语从句中做成分,可做主、宾、表语。(十一)关系代词做主语,谓语动词的单复数取决于先行词而不是关系代词。iwanttoseethefilmthatisonshow。thestudentswhodon’tstudyhardwillnotpastheexam。(十二)oneofthe与theoneofthe做先行词时谓语不一致。libaiisoneofthegreatestpoetsthathavelivedinchina。libaiistheoneofthegreatestpoetsthathaslivedinchina。thisisoneofthebooksthatihavebeenwritteninchinese。thisistheonlyoneofthebooksthathasbeenwritteninchinese。heisoneoftheboyswhoarewillingtodoit。heistheonlyoneoftheboyswhoiswillingtodoit。(十三)关系副词引导的定语从句1关系副词也可以引导定语从句关系副词在从句中分别表示时间地点或原因。关系副词when在从句中充当时间状语,where充当地点状语,why充当原因状语。1)when表示时间,充当时间状语whenoninofatwhichistillrememberthedaywhenijointhepartyiwillneverforgetthedaywhenifirstcametobeijing。但注意:1。当先行词是表地点:place,room,mountain,airport等时间:time,day,year,month,week,等原因:reason等名词时,并且分别在句中做地点、时间、原因状语时,应用where,when,why引导。但是如果如果表示时间地点原因的名词不做状语,而是做主语,宾语,或者表语时,必须用关系代词thatwhich来引导而不是用where等。istillrememberthedaythatwespenttogether。may1isthedaythatiwillneverforget。theyangtzegorgesisabeautifulplace(thatwhich)peopleallovertheworldlookforwardtovisiting。长江三峡是个美丽的地方,全世界的人都渴望来参观。themoment(thatwhich)iturnedaround,shehadleftanddisappearedinthecrowd。isthisthereasonthathegaveusforbeinglate?thisisthefactorythatwevisitedthatisthehousethathelivedin。。theplacethatwehadbeentowasfar。theshopthatwhichwesawisbeautiful。2。当先行词为bythetime,anytime,theway,everytime,thefirsttime,thelasttime时,关系词不用when而用that。或省略thisisthelasttimethatishallgiveyoualesson。thefirsttimeisawhimwasin1980bythetimehewas14hehadlearnedadvancedmathematics但如果time前无修饰语,关系词用thatwhen均可iwillneverforgotthetimewhen(that)wemetforthefirsttime。3。当先行词为way时,关系词用inwhich,that,或省略。thisisthewaythatinwhich不加hesmiles。但注意:4。why表示原因(现行词只有一个reason),做原因状语。whyforwhichthatisthereasonwhyhewaslate。(十四)学生容易出现的问题。1。在定语从句中多加了宾语,如:someoftheboysiinvitedthemdidn’tcome。someoftheboysiinviteddidn’tcome。isthisthehorseyoudrewityesterday?isthisthehorseyoudrewyesterday?2。把定语从句的动词的单复数弄错。thosewhohasfinishedmayleavetheclassroomnow。theykeyopenstheroomismissing。thosewhohavefinishedmayleavetheclassroomnow。thisisoneoftheriversinchinawhichflowsnorthward。thisisoneoftheriversinchinawhichflowsnorthward。3。省略了定语从句中做主语的关系代词。childreneatalotofsugaroftengetbadteeth。childrenwhoeatalotofsugaroftengetbadteeth。theykeyopenstheroomismissing。theykeywhichthatopenstheroomismissing。4。定语从句中加了多余的关系副词或者是介词。thehousewherehelivesinneedsrepairing。thehousewherehelivesneedsrepairing。thehousewhichthathelivesinneedsrepairing。thisisthetimeatwhenhe’smorelikelytobein。thisisthetimewhenhe’smorelikelytobein。thisisthetimeatwhichhe’smorelikelytobein。(十五)代有插入语的定语从句who与whom的选用。担主语成分时用who,担宾格成分时用whom方法:要区分是定语从句中的插入语还是主谓结构。jasonisamanwho(ibelieved)ishonest。(去掉仍成立)jasonisamanwhomibelievetobehonest。做宾语thegirlwhowesupposedwasdrownedcameback。thegirlwhowesupposedtobedrownedcameback。(十六)什么时候宜用非限制性定语从句1)当先行词是专有名词时,通常用非限制性定语从句,它本身就具有特殊性,无需在加限定。shenzhen,whichisinsouthchina,isdevelopingrapidly。myhouse,whichiboughtlastyear,hasgotagarden。mr。smithboughtanewhouseonwhichhespentallhismoney。2)当先行词是具有某一特征的人或者物中的一个,但跟非限制从句时则表示唯一的一个,compare:herroomhasawindowwhichfacessouth。herroomhasawindow,whichfacessouth。ihaveabrotherwhoisworkinginbeijing。ihaveabrother,whoisworkinginbeijing。3。当先行词表示类属意义,即表示某类动物,事物或人时,其后所跟的定语从句一般是非限制性的。asleepisausefulanimal,whosewoolhasmanyuses。football,whichisaveryinterestinggame,isnowplayedallovertheworld。
