(1)定语从句：在主从复合句中用作定语的从句叫定语从句。定语从句一般紧接在先行词后面。

(2)先行词：被定语从句修饰的成份。先行词可以为一个词，短语，或整个主句。

(3)关系词：引导定语从句的词叫关系词，分为关系代词和关系副词。关系词的作用：

A.引导定语从句，连接主句和从句，相当于一个连词；B.必在从句中作某个句子成份C,指代先行词关系词指代人或物定语从句中充当的成分关系代词that人或物主语、宾语、表语which物或主句内容主语、宾语who人主语或宾语whom人宾语whose人或物定语定语从句三步曲：

第一找出先行词；

第二找出定语从句第三看先行词在定语从句中的语法功能（做主语、宾语或状语）；结构：名词/代词（先行词）+关系代词/副词+定语从句【考点剖析】考点一：关系代词考向1：关系代词基本用法指人时可以用who，也可用that。Themanwho/thatlivesnexttousisapoliceman.Doyouknowthegirlwho/thatisinred?指物时可以用which，也可用that。Ilikemusicthat/whichIcandanceto.Whatdoyouthinkofthemoviethat/whichwasshownlastnight?活学活用：Ilovesingers.Singerswritetheirownsongs.改写：who在从句中用作主语。Heistheman.Imetthemanyesterday.改写：who在从句中用作宾语。Ilikemusic.Icandancetomusic.改写：that在从句中用作宾语。Ipreferasandwich.Asandwichisreallydelicious.改写：that在从句中用作主语。注意：1）that和who在句中做主语时不能省略，做宾语时可以省略。Ilikemusic(that)Icandanceto.Heistheman(who)Imetyesterday.2）定语从句中谓语动词的单复数应与先行词保持一致.Iprefermoviesthatarescary.Ilikeasandwichthatisreallydelicious.Ilovesingerswhoarebeautiful.Ihaveafriendwhoplayssports.Whose可以指人，也可以指物。whose在定语从句中作定语。Sheisabeautifulgirlwhosehairisbrown.Thereisadeskwhoselegsarebroken.难点：whose:属格，在从句中作定语，可指人也可指物。“whose+名词=the+名词+ofwhich”。N1+whose+N2=N1,theN2ofwhich活学活用：Lookout!Don'tgettooclosetothehouse_______roofisunderrepair.Lookout!Don'tgettooclosetothehouse，theroof_______isunderrepair.A.whoseB.whichC.ofwhichD.what

2、RecentlyIboughtanancientChinesevase,_______wasveryreasonable.RecentlyIboughtanancientChinesevase,and_______wasveryreasonable.A.whichpriceB.thepriceofwhichC.itspriceD.thepriceofwhose关系代词做宾语时可以省略。Ilikethebookthat/which/省略mymotherboughtyesterday.Doyouknowthegirlwho/whom/that/省略wetalkedaboutjustnow?5.先行词是主句内容或物，只能用as的情况。定语从句区别例句限制性定语从句中名词前有such和thesame修饰时，关系代词用as,不能用whichHeisnotsuchafoolashelooks.Don’treadsuchbooksasyoucan’tunderstand.非限制性定语从句中as和which都可以指代前面整个主句。如果有“正如，象”的含义，并可以放在主句前，也可以放在后面，那么用as；而which引导的从句只能放主句后，并无“正如”的意思。Theywonthegame,aswehadexpected.Theywonthegame,whichwehadn’texpected.Asiswellknown,heisafamousfilmstarinthe1980s.例1．【单句填空】用as\that\which填空。1.Itissuchabigstone_____nobodycanlift.2.Itissuchabigstone_____nobodycanliftit.3.______isknowntoall,heisthebeststudent.4.Jimpassedthedrivingtest,_____surprisedeverybodyintheoffice.考向2：关系代词的特殊用法考点1：先行词是人，只能用who,不能用that的情况。指人的不定代词做先行词时，只能用who.Weshouldhelpanyonewhoisinneed.非限制性定语从句中，逗号与指人的先行词隔开的句子，只能用who.I’mLiHua,whoisstudyinginLondonduringthesummervacation.考点2：先行词是物，只能用which，不能用that的情况。介词+whichTherearetwochairsintheroom,bothofwhicharebroken.非限制性定语从句中，逗号与指物的先行词隔开的句子，只能用whichTheywonthegame,whichwehadn’texpected.考点3：先行词是人或物，只能用that，不能用which或who的情况。（1）先行词被形容词最高级、序数词及only、any、few、little、no、all、oneof等修饰时。1)Iwilltellhimallthatyoutoldmeattheball.2)Theonlythingthatwecoulddowastowait.3)ThefirstplacethatwevisitedwastheGreatWall.（2）先行词为all、much、little、none、few、one、something、anything,everything等不定代词时。Thegirlhandedeverythingthatshehadpickedupinthestreettothepolice.（3）先行词中既有人又有物时。Hewaslookingpleasantlyatthechildrenandbooksthatfilledhisbus.（4）先行词在主句中作表语,关系词在从句中作表语时。Thevillageisnolongertheonethatitwas5yearsago.（5）当主句中含有疑问词which时。Whicharethebooksthatyouboughtforme?考点三：非限制性从句判断下面两个句子是限制性定语从句还是非限制性定语从句。Ilostallthemoneyyoulentmeyesterday.Ilostallthemoney,withoutwhichIhadtowalkhome.例3．【单句填空】1.Likeanything,itispossibletohavetoomuchofboth,isnotgoodforthehealth.

2.ButSarah,hastakenpartinshowsalongwithtopmodels,wantstoprovethatshehasbrainsaswellasbeauty.

【答案与解析】1.which分析句子结构可知,空格处引导非限制性定语从句,且从句中缺少主语,故填which。2.who先行词是Sarah,从句中缺少主语,所以应该用who。考点四：介词+关系代词which/whomThisisthewatch(which/that)Iamlookingfor.Thebabies(whom/who/that)thenurseislookingafterareveryhealthy.Heloveshisparentsdeeply,allofwhomareverykindtohim.IV.介词+关系代词引导定语从句的用法关系代词在定语从句中做介词的宾语时，可用介词+关系代词（whom/which）引导定语从句1.

B.where C.what D.which【答案】B【解析】考查定语从句。句意：家庭长辈，尤其是父母，应该营造一种氛围，鼓励孩子们快乐地倾诉心声。分析可知，空处引导定语从句，修饰先行词atmosphere，且关系词在从句中作地点状语，所以用where引导。故选B项。3.Learninganotherlanguageislikesteppingoutofadoor,______Icanlookbackandseemoreclearlymyownlanguage.A．Bywhich B．throughwhich C．which D．onwhich【答案】B【解析】考查定语从句和介词辨析。句意：学习另外一种语言就好像跨出了一扇房门，通过它，我可以回顾并且更加清楚地明白自己的语言。分析可知，空格处引导定语从句，根据句意可知，通过这扇门，先行词door做through“通过”的宾语，指物，用冠词代词which，by表示方式，on“在……上面”不符合句意，故选B。4.Youmaythinkofgivingupstudy,in____________casejustthinkitoverbeforemakingthedecision.A.that B.which C.whose D.where【答案】B【解析】考查定语从句关系词。句意：你可能会考虑放弃学习，在那种情况下，好好想想再做决定。分析句子可知，此句为非限制性定语从句，此空位于介词“in”后面，指代主句“Youmaythinkofgivingupstudy”，应用关系代词“which”。故选B项。5.________iswidelyaccepted,intheMiddleEastArabsgreeteachotherbytouchingnoses,butthisisnotapolitewayofgreetinginothercultures.A.As B.It C.Which D.What【答案】A【解析】考查as引导的非限制性定语从句。句意：在中东，阿拉伯人通过互摸鼻子来打招呼，这在其他文化中是不礼貌的。分析可知，________iswidelyaccepted在句中为定语从句，从句缺少主语，指代整个句子“intheMiddleEastArabsgreeteachotherbytouchingnoses”，结合选项，as和which都可以指代整个句子，在引导非限制性定语从句时，which引导的非限制性定语从句置于主句之后，as引导的从句则可以置于句首。故选A。6.Goforawalkinthecountryside,youcanenjoythebeautifulviewsandapeacefulatmosphere.A.when B.which C.where D.what【答案】C【解析】考查定语从句。句意：去乡村散步，在那里你可以欣赏美丽风景和宁静的气氛。分析句子可知，逗号后为非限制性定语从句，先行词为thecountryside（地点名词），关系词在从句中充当地点状语，应用关系副词where。故选C项。7.Ithinkyou'vegottothepoint________achangeisneeded,otherwiseyou'llfail.A.when B.where C.that D.which【答案】B【解析】考查定语从句。句意：我认为你已经到了需要改变的地步，否则你会失败的。分析可知，空处引导定语从句，修饰的先行词为地点名词thepoint，且引导词在从句中做地点状语，所以用关系副词where引导。故选B项。8.Swimmingisgoodforteenagers,________someexpertssaywillhelpthemtostimulatetheirpotentialandpromotetheirbraindevelopment.A.which B.why C.Whom D.what【答案】A【解析】考查非限制性定语从句。句意：游泳对青少年有好处，一些专家说，这将帮助他们激发潜能，促进他们的大脑发展。分析句子成分可知，“________someexpertssaywillhelpthemto….”为非限制性定语从句，修饰整个主句“Swimmingisgoodforteenagers(游泳对青少年有好处)”，所设空处可译为“这件事/这一点”，并在该句中充当宾语从句中的主语，故应用which，故选A。9.Salesdirectorisaposition________communicationabilityisjustasimportantassales.A.which B.where C.when D.why【答案】B【解析】考查定语从句的关系词。句意：销售经理是一个职位,在这个职位上,交流能力和销售能力一样重要。分析句子可知，本句为限制性定语从句，position为先行词，在定语从句中作地点状语，关系副词为where。故选B。10.Children,inmyopinion,____creativeabilityisunbelievablyrich,shouldbetrainedinthatarea.A.which B.what C.who D.whose【答案】D【解析】考查定语从句。句意：在我看来，孩子们的创造能力丰富得令人难以置信，应该在这个领域进行训练。A.which先行词是人或物，在从句中作主语或宾语；B.what引导名词性从句，在从句中作主语或宾语；C.who先行词是人，在从句中作主语或宾语；D.whose先行词是人或物，在从句中作定语。分析句子结构，结合句意可知，“____creativeabilityisunbelievablyrich”在名词Children后面作修饰成分，是非限制性定语从句，又因先行词Children和creativeability之间是所属关系，关系词在从句中作定语，用whose引导该从句。故选D。11.Communicationtechnologyhasenteredthe5Gera,________willsurelybringgreatchangestoourlife.A.when B.what C.which D.where【答案】C【解析】考查定语从句。句意：通信技术已经进入了5G时代，这必将给我们的生活带来巨大的变化。此处为非限制性定语从句修饰上文整个句子，从句中缺少主语，故应用关系代词which引导。故选C。12.Mymotheristhebusiestpersoninthefamily,whichalwayshasalotofhouseworktodo.【答案】which→who【解析】考查定语从句。句意同上。此处引导非限制性定语从句，先行词mymother，指人，在定语从句中作主语，需用关系代词who引导。故将which改为who。13.Ihaveapetcat,whichnameisLucky.Shehaswhitehairandtwobigeyes.【答案】which→whose【解析】考查定语从句。句意：我有一只宠物猫，名字叫Lucky。分析句子结构可知，此句为定语从句，先行词cat在从句中作名词name的定语，故将which改为whose。【过关检测】Ⅰ.单句语法填空1．Thereisgrowingpublic________(anxious)overlevelsofairpollutioninourcities.答案：anxiety2．Themanistalkingabouttheteachersandthings________encouragedhimgreatlyinschool.答案：that3．TheInternationalRedCrossisanorganization________purposeistohelpthesickandtheneedy.答案：whose4．Theprofessor________youwishtoseehasgoneabroad.答案：who/that/whom5．Doyouhaveanything________isimportanttotellme?答案：that6．Ashopshouldkeepastockofthosegoods________sellbest.答案：which/that7．Thisisthemostbeautifulandcleanestcity________IhavevisitedinChina.答案：that8．Membership________(quality)youforadiscountonpurchases.答案：qualifiesⅡ.句式升级1．Ihaveafriend.Helikeslisteningtoclassicalmusic.→_______________________________________________________________答案：Ihaveafriendwholikeslisteningtoclassicalmusic.2．YesterdayEmilywaswearingthenewdress.Ilentherthenewdress.→_______________________________________________________________答案：YesterdayEmilywaswearingthenewdress(that/which)Ilenther.3．Thestudent'sarticlewaspublishedinthemagazine.Iknowthestudent.→________________________________________________________________答案：Iknowthestudentwhosearticlewaspublishedinthemagazine.4．Youreferredtothemanatthemeetingyesterday.Iwanttoknowtheman.→________________________________________________________________答案：Iwanttoknowtheman(whom/who/that)youreferredtoatthemeetingyesterday.5．Theletterisfrommysister.Ireceivedityesterday.→_______________________________________________________________答案：Theletter(that/which)Ireceivedyesterdayisfrommysister.6．Thetrainwaslate.ItwasgoingtoNanning.→_______________________________________________________________答案：Thetrainthat/whichwasgoingtoNanningwaslate.7．Iwanttotalktotheboys.Theirhomeworkhasn'tbeenhandedin.→________________________________________________________________答案：Iwanttotalktotheboyswhosehomeworkhasn'tbeenhandedin.8．Theboyismybrother.Hewashereaminuteago.→_______________________________________________________________答案：Theboywho/thatwashereaminuteagoismybrother.Ⅲ.单句写作1．这些规定中的哪些是一个青少年应该遵守的？Whataresomeoftherules____________________？答案：that/whichateenagershouldobey2．远处教堂的钟声响起。Churchbellsrang________________.答案：inthedistance3．不活跃或者饮食中含有高脂肪食物的孩子会很快发胖。Children________arenotactiveor________dietishighinfatwillgainweightquickly.答案：who;whose4．他们正在等的那位老人是李教授。Theoldman__________________________isProfessorLi.答案：whom/who/thattheyarewaitingfor5．在高中你将学习更多不同于初中的课程。Inseniorhighschoolyouwillstudymorecourses________________________yourjuniormiddleschoolcourses.答案：which/thataredifferentfrom6．我们在一间窗户很大的教室学习。Westudyinaclassroom________________thewindowsareverybig.答案：ofwhich7．这是他读的第一本书。Thisisthefirstbook__________________.答案：thathehasread8．延迟兴建新医院的决定是不得人心的。Itwasanunpopulardecisionto________________________.答案：postponebuildingthenewhospital综合运用练习阅读理解Wecanmakemistakesatanyage.Somemistakeswemakeareaboutmoney.Butmostmistakesareaboutpeople.“DidJerryreallycarewhenIbrokeupwithHelen？”“WhenIgotthatgreatjob,didJimreallyfeelgoodaboutit,asafriend?Ordidheenvymyluck？”“AndPaul,whydidn'tIpickupthathewasfriendlyjustbecauseIhadacar？”Whenwelookback,doubtslikethesecanmakeusfeelbad.Butwhenwelookback,it'stoolate.Whydowegowrongaboutourfriendsorourenemies?Sometimeswhatpeoplesayhidestheirrealmeaning.Andifwedon'treallylistenwemissthefeelingbehindthewords.Supposesomeonetellsyou,“You'realuckydog.”That'sbeingfriendly.Butluckydog?There'sabitofenvyinthosewords.Maybehedoesn'tseeithimself.Butbringinginthedogputsyoudownalittle.Whathemaybesayingisthathedoesn'tthinkyoudeserveyourluck.“Justthinkofallthethingsyouhavetobethankfulfor”isanothernoisethatsaysonethingandmeansanother.Itcouldmeanthatthespeakeristryingtogetyoutoseeyourproblemaspartofyourlifeasawhole.Butishe?Wrappedupinthisphraseisthethoughtthatyourproblemisn'timportant.It'stellingyoutothinkofallthestarvingpeopleintheworldwhenyouhaven'tgotadateforSaturdaynight.Howcanyoutelltherealmeaningbehindsomeone'swords?Onewayistotakeagoodlookatthepersontalking.Dohiswordsfitthewayhelooks?Doeswhathesaysagreewiththetoneofvoice?Hisposture(姿态)?Thelookinhiseyes?Stopandthink.Theminuteyouspendthinkingabouttherealmeaningofwhatpeoplesaytoyoumaysaveanothermistake.篇章导读：本文是一篇说明文，在日常交往中，我们经常会误解他人。本文告诉我们在与他人交往的过程中要观察别人说话的表情、语调、姿态和眼神等，通过这些观察可以辨别出别人的真正想法，以避免交际中出现错误。1．Thispassageismainlyabout________.A．howtomakefriendsB．whattodowhenyoulistentootherstalkingC．howtoavoidmistakeswhenyoucommunicatewithpeopleD．whywegowrongwithpeoplesometimes答案：C主旨大意题。根据第一段前三句可知，我们经常犯的错误都是关于人的错误。文章接下来的部分告诉我们如何辨别别人的言外之意。同时结合文章最后一段最后一句可知，本文主要告诉我们在与他人交往的过程中如何避免出现错误。2．Accordingtotheauthor,thereasonwhywegowrongaboutourfriendsisthat________.A．wefailtolistencarefullywhentheytalkB．peopletendtobeannoyedwhenwecheckwhattheysayC．peopleusuallystateonethingbutmeananotherD．wetendtodoubtwhatourfriendssay答案：C推理判断题。根据第二段前三句可知，人们所说的话会隐藏他们真实的含义，如果我们不仔细听，我们可能理解不到说话人所表达的真实意思，这也是我们为什么会和朋友产生误解的原因。3．Inthesecondparagraph,theunderlinedword“it”refersto________.A．beingfriendly B．luckydogC．abitofenvy D．yourluck答案：C指代判断题。根据第二段中的“There'sabitofenvyinthosewords.Maybehedoesn'tseeithimself.”可知，在别人说你是幸运儿的时候，实际上是有点嫉妒的含义的，但是说话人自己并没有感觉到这一点。故画线词it指的是前句中的“abitofenvy”。4．Whenwelistentoapersontalking,themostimportantthingforustodois________.A．noticethewaythepersonistalkingB．takeagoodlookatthepersontalkingC．mindhistone,hispostureandthelookinhiseyesD．examinetherealmeaningofwhathesaysbasedonhismanner,histoneandhisposture答案：D推理判断题。根据最后一段内容可知，作者建议我们观察别人说话的表情、语调、姿态和眼神等，通过这些观察可以辨别出别人的真正想法。二、七选五根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。HowtoRecognizeaTrueFriendSometimesitcanbehardtorecognizeatruefriend.Hopefullythisarticlewillhelpyourecognizewhichfriendsarethekeepers.Beabletotrustyourfriends.Youshouldbeabletotrusttruefriendsandtheyshouldreturnthistrust.Doyourfriendstellyousecretsthatnooneelseknows?Askyouforadvice?__1__However,ifyourfriendshidethingsfromyouandactsecretly,thenthisisasignthattheymaynottrustyou.__2__Thinkaboutit.Howcomfortableareyourfriendswhentheyarearoundyou?Aretheybeingthemselvesaroundyou?Aretheyactingfakeorperhapshidingsomething?Truefriendshipscantakeawhiletodevelop,butifyourfriendsaretruetheyshouldfeelcomfortablearoundyou,andviceversa(Youwiththem)．Thinkaboutloyalty(忠诚).__3__Ifyouareinneedofahelpinghand,yourtruefriendsshouldbetheretoofferittoyou.Truefriendsdon'ttrytogetoneanotherintotrouble.Atruefriendwillalwaysbeloyaltoyouandwillnotrevealsecrets.Thinkaboutnicknames.Alotoftruefriendslovetogiveeachothernicknames!Ifyourfriendisgivingyounicknames,thenthisisagreatsign.Thinkofthenicknameyourfriendhasgivenyou,doesitsuityouwell?__4__Lookathowyoufight.Nearlyallbestfriendsfight.__5__Truefriendswillfindtheirwaythroughafight,nomatterwhatthesizeis.Truefriendswillremain“faithful”toeachotherevenduringafight.Theywillnottelleachothers'secrets,andtheystillcareabouteachother.A．Considercomfort.B．Chooseyourfriendscarefully.C．Truefriendsarealwaysthereforoneanother.D．Botharesuresignsthatyourfriendtrustsyou.E．Ifso,thisshowsyourfriendmustknowyouquitewell.F．Soifyouandyourfriendhavealittleargument,don'tworry!G．Aninsidejokeshowsthatyoushareaspecialconnectionwithyourfriend.篇章导读：本文是一篇说明文，介绍了如何识别一个真正的朋友。1．D根据设空前两句“Doyourfriendstellyousecretsthatnooneelseknows?Askyouforadvice?(你的朋友会告诉你没有其他人知道的秘密吗？征求你的意见吗？)”和下一句的转折“However,ifyourfriendshidethingsfromyouandactsecretly,thenthisisasignthattheymaynottrustyou.(然而，如果你的朋友
