改错题常考要点一、代词代词中主要讲解六个问题一掌握代词的几种格主格、宾格、所有格名词前面用代词来修饰只能用所有格mybooks二反身代词当主语和宾语表示同一事物时宾语使用反身代词。Hekilledhimself.他自杀了Hekilledhim.他杀了他例ResearchersattheUniversityofColoradoareinvestigatingABaseriesofindicatorsthatcouldhelpCthemselvestopredictearthquakes.D分析D错应改为them。如果用反身代词themselves指代对象是从句主语that即名词indicators这显然是错误的。从句意来看help的宾语应该是主句主语researchers故应用代词宾格而不是反身代词。注意C并没有错情态动词could比can语气弱表示较小的可能性。Indicator为征兆这些征兆帮助他们来预言地震。主语是征兆后面指研究者不是同一个事物三代词的单复数代词的性别在考试中如果代词打横线代词错误的概率是非常高的因此代词打横线应该先看代词有没有错。例ThecontinentaldividereferstoanimaginarylineintheNorthAmericanRockiesthatdividesthewatersflowingintotheAtlanticOceanfromitflowingintotheABCDPacific.分析D错应改为those。D指代复数名词watersit是单数显然是错误的根据习惯故改为those。注意waters一词并没有错它指江湖河海中的大片水域可用复数形式。Water作为水是不可数名词waters表示水域通常使用复数形式作主语谓语动词用复数。Work作为工作是不可数名词work作为作品可数不可数都可以例如Manyofhisworksmuchofhisworkwork都表示作品例In1920thepresidentialcandidateWarrenHardingcoinedAtheword“normalcy”toexpresssocialandBeconomicconditionstheypromisedthenation.CD分析D错应改为he。动作promised是由WarrenHarding发出来的故用第三人称单数he来指代。例ManycriticsbelievethatAmyLwellsmostimportantAworkisnotpoetrybuthisbiographyJohnBCKeatspublishedtheyearofherdeath.D分析C错应改为her。his指男性显然是错误的应改为her与后面的her同指AmyLowell.四Who和which的区别which指代事物或者动物who指代人who/whomson往往要改为whosesonwhose可以指代事物例ThehumanbodycontainsmorethansixhundredmuscleswhoABaccountforapproximatelyfortypercentofthebodyweight.CD分析B错应改为which或that。先行词不是指人而是指物关系代词不能用who故改为which或that。人体前面加定冠词theaccountfor占有多大的比例解释说明五that和which的区别介词后面使用which而不用thatinthat除外例WhentelevisionwasfirstintroducedtheextenttothatitABwouldaffectsocietycouldnothavebeenforeseen.CD分析B错应改为which。Theextenttowhich介词加which引导定语从句影响社会的程度没有被预见六定语从句的特殊省略Reason后面有定语从句中间往往省略whyTime后面有定语从句中间往往省略whenIdorememberthetimeIheardthesweetestvoiceinthewildworld.way后面有定语从句中间省略了inwhich例ResearchonpainhasbeenneglectedalthoughthemainlyABreasonpeopletakemedicineistorelievepain.CD分析B错应改为main。mainly为副词不能个饰后面的名词故改为形容词main。句子中peopletakemedicine修饰reason定语从句引导词被省略例CommercialexpansionfromcitytosuburbhasaffectedthewaypeopleintheUnitedStates----
