1、Period ThreeGrammar & Writing一、引导定语从句的关系词1引导定语从句的常用关系词及其用法关系词指代对象在从句中所作成分关系代词who指人主语、宾语、表语whom指人宾语which指物主语、宾语、表语that既指人又指物主语、宾语、表语whose既指人又指物定语as既指人又指物主语、宾语、表语关系副词when指时间时间状语where指地点地点状语why指原因原因状语Thereareoccasionswhen(onwhich) onehastoyield.任何人都有不得不屈服的时候。Beijingistheplacewhere(inwhich) Iwasborn.北京是

2、我出生的地方。2定语从句中关系词的选用方法一：用关系代词还是关系副词取决于从句中的谓语动词。如果是及物动词，就要用关系代词；如果是不及物动词，要用关系副词。ThisisthemountainvillagewhereIstayedlastyear.这是我去年待过的山村。Theletterthat/whichIreceivedyesterdaywasfrommyfather.昨天我收到的那封信是我父亲寄来的。方法二：准确判断关系词在定语从句中所作的成分(主语、宾语、定语、状语)，也能正确选择出关系代词/关系副词。关系词在从句中作主语、定语、宾语时，应用关系代词(who，whom，that，whic

3、h，whose)；关系词在从句中作状语时，应用关系副词(where作地点状语，when作时间状语，why作原因状语)。3that和which引导的定语从句的区别that和which都是关系代词，都可在从句中作主语或宾语，但两者存在着不同：用that不用which的情况先行词是all，much，few，little，everything，anything，nothing，none，theone等不定代词时先行词被all，few，little，much，every，some，no等词修饰或被theonly，thevery，thesame，thelast，theright，just等限定词修饰时先行

6、winter?(5)Whichisthedressthatfitsmemost?二、“介词关系代词”的用法1“介词关系代词”结构中介词的确定方法。(1)根据从句中的谓语动词或主要的形容词确定介词。Thewitnesstowhomthepolicemenreferredwaskilledlastnight.警察所提到的那个目击证人昨晚被杀了。(2)根据定语从句修饰的先行词确定介词。Idontknowthereasonforwhichhewaslateforschool.我不知道他为何上学迟到。(3)根据句子所要表达的意思确定介词。Thisisthepilotbywhommysonwassaved

7、.这就是那位救了我儿子的飞行员。2“介词关系代词”结构中的关系代词通常用which或whom，不用that。IllneverforgetthedayonwhichIjoinedthearmy.我永远也忘不了我参军的那一天。ThisisthepencilwithwhichIdrawpictures.这是我画画用的那支铅笔。3关系副词where，when，why可替换成“介词which”，介词取决于先行词及“介词which”在从句中的作用。why可替换为forwhich。ThisisthehouseinwhichIlivedtwoyearsago.ThisisthehousewhereIlived

8、twoyearsago.这就是两年前我居住的那个房子。4“不定代词或数词介词which/whom”引导的定语从句说明整体中的部分。Lastweek，onlytwopeoplecametolookatthehouse，neitherofwhomwantedtobuyit.上周只有两个人来看房子，他们两个人都不想买。5“the名词ofwhich”可替换“whose名词”，引导定语从句。Thehouse，thewindowsofwhich(whosewindows) weredamaged，hasnowbeenrepaired.窗子遭破坏的那所房子现在已经修好了。即时跟踪2用适当的关系词或“介词关系

10、起补充说明的作用，删掉后不影响整个句子意思的表达)不用逗号隔开一般用逗号隔开可用that引导不可以用that引导只可以修饰先行词，不可以修饰主句或主句的一部分既可以修饰先行词，也可以修饰主句或主句的一部分即时跟踪3用适当的关系词或“介词关系代词”填空(1)Iwalkeduptothetopofthehillwithmyfriends，where/onwhichweenjoyedasplendidviewofthelake.(2)Pleasepassmethebook，whosecoverisblue.(3)Manypeopletriedtoleavethecountry，wheretherew
