1、高一定语从句讲解嘉定二中高一英语组第一讲1、功能：相当于形容词，修饰名词或代词，在句中作定语一：先行词：被定语从句所修饰的词二：关系代词：用来连接定语从句，并在从句中代表先行词的代词。先行词是物：whichthat先行词是人：whowhomthat在从句中充当的成分：主语、宾语（1）先找关系词，看先行词指的是什么。（2）看关系词在从句中所充当的成分。e.g.把下列每对句子合并成含有定语从句的主从复合句1.Theyhadaradio.Itcouldsendoutmessages.Theyhadaradiowhich/thatcoul

2、dsendoutmessage.(主语)2.Thegirlismybestfriend.Shespokejustnow.______________________________________________________3.Healwaysbuyssomebooks.Heneverreadthem.______________________________________________________注意点：1.）定语从句一般直接跟在先行词的后面：e.g.4.Themanwholivesnextdoorsellsveg

3、etables.Themansellsvegetableswholivesnextdoor.(×)5.Thecarwhichmyunclejustboughtwasdestroyedintheearthquake.Thecarwasdestroyedintheearthquakewhichmyunclejustbought.(×)2．）关系代词在从句中作宾语时可以省略：e.g.6.Theyoungman(whom)yousawwasourmanager.7.Thereissomething(that)wemustkeepinmin

4、d.找出句中的从句并圈出先行词说出关系代词在从句中的成分1.Themanwhotoldmethenewsrefusedtogivemethename.2.TheairlinehasabookletwhichwilltellyoumostoftheimportantthingsaboutatriptoEurope.3.Hefoundadollarbillthathehadforgotteninasuit.4.Heisthemanwhomweallrespect.5.Thereissomebodywhowantstoseeyou.6.

5、ThehouseIwouldliketobuyisnotforsale.7.Thebicyclemyunclegavemewasveryexpensive.第二讲whose的用法：关系代词与其后的名词构成所有格，即“的”时，它既可以修饰指人的先行词，也可以修饰指物的先行词。e.g.1.Thegirlismydaughter.Herworkgotthefirstprize.Thegirlwhoseworkgotthefirstprizeismydaughter.2.Thebookisnotmine.Thecoverofitisred

6、.Thebookwhosecoverisredisnotmine(Thebookthecoverofwhichisredisnotmine)3.Doyouknowanyone?HisfamilyisinXi’an.________________________________________________________________4.Iliveintheroom.Thewindowsofitfacesouth.________________________________________________________

7、________5.Thechairhasbeenrepaired.Thelegofitwasbroken.________________________________________________________________限制性定语从句与非限制性定语从句1、限制性定语从句：从句与主句关系密切，去掉从句，主句意义不完整，甚至不合逻辑。e.g.Iwastheonlypersoninourofficewhowasinvited.（去掉定语从句，意思就不完整）2、非限制性定语从句：从句对先行词关系不密切，去掉定从句，意思仍然

8、完整。形式上用逗号隔开，不能that用引导。e.g.Tom’sfather,whoisoversixty,stillworksharddayandnight.（who引导非限制性定语从句，整个句子可分成两句来翻译）that与which的区别1）用t
