justasinternationalastheywereatthetimewhenpeopletravelledtheSilkRoad．定语从句的种类根据定语从句与先行词之间关系的紧密程度，我们将定语从句分为限制性定语从句和非限制性定语从句两种。1．限制性定语从句限制性定语从句

是先行词在意义上不可缺少的定语，用于修饰和限定先行词。如果去掉，主句的意思就不完整。这种从句和主句的关系十分密切，两者之间不用逗号分开；关系代词在从句中作宾语时可以省略。引导限制性定语从句的关系代词有who,whom,whose,that,which,

as；关系副词有where,when,why。◆Thisisthecomputer(that/which)heboughtforhissonyesterday．这是他昨天为儿子买的电脑。◆Thewomanwho/

thatsurvivedtheearthquakeisAmy’sEnglishteacher．在地震中幸存的那个女人是埃米的英语老师。◆Ilivenextdoortoacouplewhosechildrenoftenmakealotofnoise．我隔壁住着一对夫妇，他们的孩子经常吵闹。2

．非限制性定语从句非限制性定语从句和主句的关系不是十分密切，只是对先行词或主句做些附加说明，如果去掉，主句的意思仍然完整。这种从句和主句之间往往用逗号分开。引导非限制性定语从句的关系词与引导限制性定语从句的关系词略有不同。除that和why不能引导非限制性定语从句外，其他都可以。◆He

isEnglish,whichIknowfromhisaccent．他是英国人，那是我通过他的口音知道的。◆Iheardaterriblenoise,whichbroughtmyheartintomymouth．我听到了一个可怕的声音，这使我非常害怕。【即时演练1】——用适当

的关系词填空①Holly,whoisfromAustralia,hasagoodcommandofChinese．②(2018·北京卷)Sheandherfamilybicycletowork,whichhelpsthemkeepfit．③Hisparentswouldn’tmarryhertoa

nyonewhosefamilywaspoor．限制性定语从句与非限制性定语从句的用法比较1．形式不同限制性定语从句和主句之间没有逗号；非限制性定语从句必须用逗号与主句隔开。◆Hereisthemanwhohasbeen

punishedbytheboss．这就是那个被老板惩罚的人。(限制性定语从句)◆Theproject,whichlastedthreeyears,costnolessthan$1billion．这个工程

历时三年，耗资多达十亿美元。(非限制性定语从句)2．先行词不同限制性定语从句的先行词只能是一个名词或代词，而非限制性定语从句的先行词可以是一个词，也可以是整个主句。试比较：◆ThisisthebestnovelthatIhaveeverrea

d．这是我曾经看过的最好的小说。(限制性定语从句，先行词是novel)◆Thenovel,whichIreadlastnight,isveryinteresting．我昨天晚上看过那部小说了，它非常有意思。(非限制性定语从句，先行词为novel)◆Thenovelisveryinter

esting,whichmakesmeveryexcited．那部小说很有意思，这让我很兴奋。(非限制性定语从句，which指代前面整句话的内容)3．关系词的使用情况不同(1)that,why不可用于引导非限制性定语从句，指物时要用which代替that,forwhich代

替why◆Mostpeopledidn’tvoteforhim,whichdisappointedhim．大多数人没有投票支持他，这使他感到失望。◆Ihavetoldthemthereason,forwhichIchangedmymind．我已经告诉了他们

我改变主意的原因。(2)关系代词替代情况不同①关系代词whom在限制性定语从句中作宾语时可用who代替，但在非限制性定语从句中作宾语时不可用who代替。◆Thisistheman(whom/who/that)wearetal

kingabout．这就是我们正在谈论的那个人。(限制性定语从句)◆Theoldwomanhasthreesons,whomsheisproudof．这位老妇人有三个引以为豪的儿子。(非限制性定语从句)②在限制性定语从句中，先行词指人时可以用that引导，但在非

限制性定语从句中先行词指人时，关系代词只能用who或whom。◆Shehasayoungerbrother,whoisanEnglishteacher．她有一个弟弟，他是一名英语老师。(3)关系代词省略情况不同关系代词在限制性定语从句中作宾语时可省略，而非限制

性定语从句的所有关系代词均不可省略。◆Thisisagoodfilm(which/that)Isawafewdaysago．这是我几天前看过的一部好影片。(限制性定语从句)◆Thesummerholiday,whichwe’relookin

gforwardto,isdrawingnear．我们盼望的暑假就要来了。(非限制性定语从句)(4)非限制性定语从句由“介词＋关系代词”引导时，其中的关系代词用which或whom◆Sevenpeoplewerecaughtint

hebigfirethatbrokeoutonFriday,fourofwhom(＝ofwhomfour)werebadlyinjured．七人被困在星期五发生的大火里，其中四人严重受伤。◆Ihaveboughttwopens,bothofwhichwr

itewell．我买了两只钢笔，写起来都很好用。【即时演练2】——完成句子①她的姐姐明年将要出国，她教我们英语。Hersister,who_teaches_us_English,_willgoabroadnextyear．②这就是怀特先生，你等了很久的人。Her

eisMr．White,whom_you’ve_been_waiting_foralongtime．③她找到了那条两周前丢失的项链。Shehasfoundthenecklace(that)_she_lost_two_weeks_ago．Ⅰ用适当的关系词填空，

忽视的一部分。2．A解析：此空设于段末，与上文之间存在逻辑上的解释关系。此空是对“self-full”的解释说明。3．B解析：此空设于段首，是本段的主旨句。后面提到的内容都是围绕要让他们列出他们积极的品质展开的。4．G解析：此空设于段中，与上文之间存在逻辑上的因果关系。每个人都有不同的能力、

品格和激情。因此，你应该告诉他们要敢于接受自己的优点和缺点。5．E解析：此空设于段中，与上文之间存在逻辑上的解释关系。此空是在举例说明帮助他人的方式。Ⅳ语法填空Doyouknowpolarbearswell?Inthisarticle,wewilldiscusssome1．________

查动词的语态。which指代主语blackskin，故谓语动词用单数，又因为blackskin与cover构成动宾关系，故填iscovered。3．its解析：考查代词。因为后面跟名词，故用其形容词性物主代词，故填its。4

．reflects解析：考查主谓一致。主语是that，指代ahollowtransparenttube(中空透明管)，因此谓语动词用单数形式，故填reflects。5．places解析：考查名词的数。此处泛指“寒冷的地方”，因为place是可数名词，故填places。6．to

解析：考查固定搭配。thanksto是固定搭配，意为“多亏；由于”，故填to。7．faster解析：考查副词的比较级。因为前面有abit修饰，后面跟than，且用来修饰动词melt，故用副词的比较级形式。8．tohunt解析：考查非谓语动词。此处是不定式作后置定语，故填tohunt。9

．where解析：考查定语从句的引导词。先行词是countries，在从句中作状语，故填where。10．from解析：考查介词。preventsb．fromdoingsth．是固定句式，故填from。
