刘艳第一步:先看先行词指物用:which/that指人用:who/whom(宾语)第二步:再看先行词在句子中担当的成分主语(which/that、who)宾语(whom/which/that/省略)定语(whose)第三步:从句不却成分用关系副词时间:when(先行词一般是days;hours;或者具体的表时间的词,像年份,点钟;月份;早中午;季节等等。。Occasion也用when或onwhich)地点:where(表示地方的词,比如具体的地名;或者图书馆、学校、电影院等场所词;还有一些不是明确表示地点的,这个时候先行词为一些表示点或者场景的名词。如situation;case;spot;activity;point;job;business;circumstance)原因:why(先行词一般为reason)Which的独特用法1.在非限制性定语从句中,可以代替前面整件事,其他词没有此用法;2.Which可以和介词连用,相当于关系副词在句子中做状语。3.指人的时候,介词只能和whom连用。e.g.YesterdayIcameacrossafewfriendswithwhomIwenttothesupermarket.That的独特用法先行词为all,everything,nothing,something,anything,little,much等不定代词时。Iamsureshehassomething(that)youcanborrow.先行词被all,every,no,some,any,little,much等修饰时。2.I’vereadallthebooksthatarenotmine.先行词被序数词或最高级修饰时。3.Thisisthefirstbook(that)hehasread.先行词被theonly,thevery,thesame,thelast修饰时4.Thisistheverybookthatbelongstohim.5.既指人又指物时5.Boththebookandthewriterthatarefamousarepopular.6避免重复,两个从句,前一个用which/who,后面就用that.Whowasthepersonthatcametovisityou?注意:1.As在定语从句中代替整件事或者前面整句话,而且通常在句子开头。也可以在句子中间,类似于插入语。通常解释为“正如…”e.g.Asweallknow,thesuntravelsaroundtheearth.2.先行词为way这个词时只能用that或者inwhich或者省略e.g.theway(that/inwhich)onebehaveswaystypeofpersonheis.3.先行词为theplace(where)helivedwhenhewasachild.4.先行词为thereason(why)herefusedtohelpme.1.________isknowntoeverybody,themoontravelsroundtheearthonceeverymonth.A.ItB.AsC.ThatD.What2.__________ismentionedabove,thenumberofthestudentsinseniorschoolisincreasing.A.WhichB.AsC.ThatD.It3.Allgoeswell_____(is)planned.A.WhichB.AsC.ThatD.It先行词人物主语Who/thatWhich/that宾语Who/that/whomWhich/that所有格whoseWhose/ofwhich1.Thegirl___who___issittinginthechairisagoodsinger.2.Thefirstskirt__________Maryboughttwoyearsagoisold.3.Isthisthelastnovel_______youintroducedtome?4.Whereistheboy_______brokethewindow?who/that(that)(that)who/that
