epropertherestrictiverelativeclauses.【学习过程】【自主探究】Step1:语法自主探究定语从句（一）——关系代词的用法在复合句中,修饰名词或代词的从句叫__________

___。定语从句通常由______或关系副词引导，说明事物的具体信息，从句位于被修饰词_________。被定语从句修饰的词叫__________，引导定语从句的词叫_____________，关系词指代先行词，并在定语从句中充当成分。关系词有两种：关系代词_____________

________________和关系副词when,where,why。根据定语从句与先行词的关系，可将定语从句分为______________和非限制性定语从句。一般说来，限制性定语从句是整个句子_____________的部分，如果省略会影响全句的

主要意思，这种定语从句前面不用_____________隔开；而非限制性定语从句的作用是对所修饰的成分作进一步说明,通常和主句用逗号隔开，将从句去掉后句子的意思仍然完整，译成汉语时，从句常单独译成一句话，除了that和why不能引

导非限制性定语从句，其他关系词的用法和限制性定语从句关系词的用法相同。关系代词的用法一、判断定语从句的关系代词的方法：如果名词或代词后有一个句子，并且该名词或代词在句子中充当成分，则该2/18句子就是定语从句。主要按照以下三步来

判断：1．找准__________（定语从句前的名词或代词）。2．把先行词还原到定语从句中，看充当______________。3．根据先行词在定语从句中所充当的成分以及句意来选用适当的_________。如果先行词在从句中作主语，宾语，定语，表语，则用

____________，关系代词主要有who,whom,whose,that,which,as。二、关系代词的基本用法指代关系代词例句1.人Who、whom、thatTheman_____________isspeakingatthemeetin

gisafamousscientist.（作isspeaking的主语）在会上讲话的人是一位著名的科学家。He_________doesnotreachtheGreatWallisnotatrueman.（作doesnotreach的主语）不到长城非好汉。

Thisisthefamousscientist(_____________)wevisitedlastweek.（作visited的宾语）这就是我们上周拜访的那位著名科学家。2.物That、whichHefinallyworkedouttheproble

m______________puzzledhimforalongtime.（作puzzled的主语）他最后解出了这个令他困惑很久的问题。Thefish(______________)weboughtyesterdaywerenotfresh.（作bought的宾

语）我们昨天买的鱼不新鲜。3.人的；物的whoseTheyrushedovertohelptheman____________carbrokedown.（whosecar=theman’scar，作定

语，修饰car）他们跑过去帮助那个汽车抛锚的人。Thereisamountain______________topisalwayscoveredwithsnow.(whosetop=themountai

n’stop，作定语，修饰top)有一座山顶常年被雪覆盖的山。3/184.句子（在非限制性定语从句中）Which、asTheweatherturnedoutverygood,____________wasmorethan

wecouldexpect.（which指代“天气最后晴朗起来”，作was的主语）天气最后晴朗起来，这是我们没有料到的。______________everyoneknows,Chinaisabeautifulcountrywithalonghistory.（As指代“中国是一个有着悠久历史的

美丽国家”，作knows的宾语）每个人都知道，中国是一个有着悠久历史的美丽国家。三、关系代词易错点：1.关系代词的省略关系代词在定语从句中作_________时，不可省略；做宾语时，在限制性定语从句中可以省略，在非限制性定语从句中不可省略。Isheth

emanwho/thatwantstoseeyou?(作wants的主语不可省略)他就是那个想见你的人吗？Hangzhouisabeautifulcity(___________)Ialwayswanttovisit.（在

限制性定语从句中作visit的宾语，可以省略）杭州是我总想参观的一个美丽城市。Hangzhou,_____________Ivisitedlastweek,isabeautifulcity.（在非限制性定语从句中作visited的宾语，不可省略）杭州是一个美丽的城市，我上周去

参观过。2.从句中代词的重复多余定语从句中的引导词指代先行词，并在从句中作成分，从句中不能再出现指代该先行词的代词。判断正误ThebookthatIreadityesterdayisveryinteresting.（）Thebook

thatIreadyesterdayisveryinteresting.（）ThisisthewomanwhoImetherlasttime.（）ThisisthewomanwhoImetlasttime.（）3.关系代词和代词的误

用定语从句的引导词要用关系判断正误Thisistheboyhetoldmeastoryyesterday.（）4/18代词，而不能用一般代词。Thisistheboywhotoldmeastoryyesterday.（）Thisistheboyhisfatherisourheadma

ster.（）Thisistheboywhosefatherisourheadmaster.（）4.what不引导定语从句定语从句中有关系代词that和which，而没有what，what可以引导名词性从句。Allthatweneedis

asupplyofoil.(that引导定语从句，修饰先行词all)Whatweneedisasupplyofoil.(what引导主语从句)我们需要的是石油供应。5.that不引导非限制性定语从句（用逗号隔开）在非限制性定语从句，不能用关系代词that。如果

指代“人”，用关系代词who/whom，指代“物”，用关系代词which。Thebasketballstar,_____triedtomakeacomeback,attractedlotsofattention.这位打算复出的篮球明星引起了很多关注。

Beijing,____________isthecapitalofChina,isabeautifulcity.中国的首都北京是座美丽的城市。Hehasbecomeadoctor,_________hewantedtobe.他成为了一名医生，这是他以前一直梦想的。6.介词+w

hich/whom先行词在从句中作介词宾语，若介词提前，指代物时，只能用which，不用that；指代人时，只能用whom，而不用who。介词不提前时，用that/which,who/whom都Ihavethebook

about____________youaretalking.=Ihavethebook(that/which)youaretalkingabout.我有你现在谈论的那本书。Themanwith_____________ItalkedjustnowisfromBeijingUniversi

ty.=Theman(who/whom/that)ItalkedwithjustnowisfromBeijingUniversity.刚才和我谈话的那个人是从北京大学来的。5/18可以。7.whose+n.=the+n+ofwhich=ofw

hich+the+n.whose+n.可与the+n+ofwhich互换，而且ofwhich也可置于名词之前，名词之前必须有定冠词the。Iliveintheroom_________windowfacessouth.(whosewindow=thero

om’swindow)Iliveintheroomthewindowof_________/ofwhichthewindowfacessouth.(thewindowofwhich=thewindowoftheroom)我住在窗子朝南开的房间里。8.定语从句中的主谓一致：关系代

词在定语从句中做主语时，定语从句的谓语通常与先行词在人称和数上保持一致。注意：当先行词为“oneof+复数名词”时定语从句的谓语动词用复数形式；当先行词为“the(only/very)oneof+复数名词”时定语从句

的谓语动词用单数形式。Heisagoodstudent____________likestohelpothers.他是一个乐于助人的好学生。Theyaregoodstudents_____________lik

etohelpothers.他们是乐于助人的好学生。Heisoneofthestudents__________________praised.他是一个受到表扬的学生之一。Heistheone/theonlyoneofthestudents______________praised.他是唯一

一个受到表扬的学生。四、易混的关系代词辨析：（一）that和which1.用that，不用which的情况①当先行词为不定代词：everything,anything,nothing,all,any,much,many,some,few,little,none等或当先行词

被no,some,any,all,much,little等词修饰时，只能用that。Togetthejobstarted,allthatIneedisyourpermission.要开始工作，我所需要的是你的许可。Isthe

reanythingthatIcandoforyou?有什么要我做的事吗?Heansweredfewquestionsthatwereaskedbythereporters.他几乎没有回答记者提问的问题。6/18②当先行词被theon

ly,thevery,thesame等词修饰时。That’stheonlythingthatwecandonow.目前我们只能这样了。ThisistheverypenthatIamlookingfor.这正是我找的钢笔。Hestilllivesinth

esamehousethatwevisitedtenyearsago.他还住在十年前我们参观的同一座房子里。③当先行词被序数词、形容词最高级修饰时。Thiswasoneofthemostinteresting

books______________weresoldinthisbookstore.这是这家书店售出的最有趣的书之一。Thefirstthing________________shouldbedonei

stogetsomefood.该做的第一件事是弄点吃的。④当先行词中同时包括人和物时。I’mgoingtotalkaboutthecountriesandpeople_________________Ihavevisited.我要谈论一下我所访问的国家和人民。⑤当要避免与疑问词which重

复时。WhichistheT-shirt_____________fitsmemost?那件体恤衫最适合我？2.用which，不用that的情况①在非限制性定语从句中Football,____________isaninteres

tinggame,isplayedallovertheworld.全世界都踢足球，它是一项有趣的运动。②介词提前时，不用that，而用which，介词不提前时，用that和which都可。Thisistheroomin__________myfatherlivedlastyear

.=Thisistheroom(that/which)myfatherlivedinlastyear.这是我父亲去年居住过的房子。（二）which和as（引导非限制定语从句，指代整个主句内容）1.位置上的区别：as引导的从句可放在主句首、句末或句中。而which______________iskn

owntousall,theearthturnsaroundthesun.Theearth,__________isknowntousall,turnsaroundthe7/18引导的从句只能放在主句之后。sun.Theeartht

urnsaroundthesun,___________isknowntousall.众所周知，地球绕着太阳转。2.语义的区别：as有“正如”之意，因此主句和从句语义一致，而which表示“这一点”在意义上相当于一个并列句，可以用andthis代替，在语

义上可以不一致。Mikewonthefirstprize,_______wasexpected.正如所料想的,迈克获得了一等奖。Mikewonthefirstprize,__________wasnotexpected.迈克获得了一等奖，这一点没被料想到。五、as引导的定语从句的用法（一）as

引导的定语从句1.在限制性定语从句中，先行词有such,so,as,thesame修饰时，引导词用as。比较：Ihaveneverreadthebookthatyouhavetalkedabout.我从未读过你谈到的这本书。Ihaveneverreadsuchanintere

stingbookasyouhavetalkedabout.=Ihaveneverreadso/asinterestingabookasyouhavetalkedabout.我从未读过像你谈到的这样有趣的书。2.在非限制性定语

从句中，指代整个主句内容。Asweknow,sheisagoodteacher.我们都知道她是一个好老师。Lily,asweexpected,wonthefirstprizeinthecompetitionyesterday.像我们

所期望的那样，莉莉在昨天的比赛中获得了一等奖。（二）易混句式辨析1.such/so…as…和such/so…that…①such/so…as…表“像„„这样的„„”，用来引导定语从Thisissuchahea

vystone__________noonecanlift.（作lift的宾语，是定语从句）8/18句（as在从句中充当主、宾或表语等）②such/so…that…表示“如此„„以致„„”，用来引导结果状语从句。Thisissuchahea

vystone_____________noonecanliftit.（不缺成分，是结果状语从句）这是一块如此重的石头，没人能搬得动。2.thesame…as…和thesame…that…①thesame…as…表示“

类似的一个，而不是同一个”（相似性）②thesame…that…表示“同一个”（同一性）Ihaveboughtthesamewatch_____________youhave.我买了一块和你的一样的手表。（相似的，非同一个）Thisisthesamewatch_______

_______Ilost.这就是我丢的那块手表。（同一个）【课后巩固】一、用正确的关系代词填空1.Thetrees________standbytheriverwereplantedbyus.2.Shenevergivesintothose_

过来；（2）能够先通过读题，找到题干中的关键词。【课前诊断】很多学生在练习听力之前盲目或者不知重点，有些在听力的准备阶段不明确自己读题的意义在哪里，就是因为不会寻找并抓住关键信息的体现。而本节课的学习重点就是这个，要让学生
