做題三步曲：

步驟一：首先把主句和從句區(qū)分開來，識(shí)別出名詞性從句。步驟二：分析從句缺何種成分。步驟三：根據(jù)分析，選擇恰當(dāng)?shù)倪B詞。

22一、單句填空用適當(dāng)?shù)倪B詞填空。

靈活運(yùn)用1.Thenewboylookedattheteacherforafewsecondsandalltheotherstudentswondered______theboywoulddo.

2.Oneday,hecameupwithanidea_____hewouldpluckupallofhiscropafewinches.Hedidsothenextday.that一、單句填空用適當(dāng)?shù)倪B詞填空。靈活運(yùn)用1.Then23二、語篇填空Ilikereadingverymuch.Myclassmates’questionis1______Ibegantolovereading.Actually,Ilovereadingasachild.IgrewupinacollegetownandIspentallmysummervacationsinthisuniversity.WhatImeantwas2______Iwassurroundedbylibrariesandthepeoplewholovedtoread.3______Iwenttothelibrarytoreadeverydaywasoneofmyfavoritehobbies.whenthatThat二、語篇填空Ilikereadingvery24Myloveofreadingwascreditedwiththefact4_____myparentsonlyletmewatchanhourofTVaday.Ilearnedtoentertainmyselfthroughmymindandimagination.It’snotreallysurprising5_____literaturebecamemyvocation.RecentlyIhavebeenreadingalotofmulticulturalwomen’slegends.JaneGoodallwenttoAfricaandstudiedchimpsinsteadofgoingtouniversity.thatthatMyloveofreadingwascredite25Sheargued6______wildanimalsshouldbeleftinthewildandnotusedforentertainment.Afterfinishingherstory,Istillhavesomedoubts7______shecouldachievegreatsuccessonherownintheforest.LinQiaozhi,adoctor,becameaspecialistinwomen’sillnesses.ShedevotedallherlifetomedicalworkforChinesewomenandchildren.8_____madehersucceedlateronwasthekindnessandconsiderationsheshowedtoallherpatients.9______shedidn’tchoosetohaveafamilyofherowniscleartomenow.thathowWhatWhySheargued6______wildanimal26三、單句改錯(cuò)1.ExactlyhowthetomatowasintroducedintoEuropeisuncertain,butitwasprobablyaround1565.how→when

由1565可知，不能確定的是番茄被引入中國(guó)的“時(shí)間”，故用when引導(dǎo)主語從句，在從句中作時(shí)間狀語。三、單句改錯(cuò)1.Exactlyhowthetoma272.Grandmapointedtothehospitalandsaid,“That’swhenIwasborn.”when→where

醫(yī)院應(yīng)是她出生的“地點(diǎn)”，故用where引導(dǎo)表語從句，在從句中作地點(diǎn)狀語。2.Grandmapointedtothehosp283.“Everytimeyoueatasweet,drinkgreentea.”Thisisthatmymotherusedtotellme.that→what

意思是“這就是我兄弟以前常常跟我說的”，在表語從句中作tell的賓語，故用連接代詞what。4.Itmakesthebooksoextraordinaryisthecreativeimaginationofthewriter.It→What

引導(dǎo)主語從句并在從句中作主語，用連接代詞what。3.“Everytimeyoueatasweet295.Fromspace,theearthlooksblue.Thisishowaboutseventy-onepercentofitssurfaceiscoveredbywater.how→because

因“71%的地表為水所覆蓋”是“地球看起來是藍(lán)色”的原因，故用because引導(dǎo)表語從句。5.Fromspace,theearthlooks306.Itsuddenlyoccurredtohimhehadlefthiskeysintheoffice.在he前加that

句中it作形式主語，that引導(dǎo)主語從句。7.Asmanyasfivecoursesareprovided,andyouarefreetochoosewhateversuitsyoubest.whatever→whichever

指在前面提到的五種課程中“任選一種”,有選擇范圍，要用whichever引導(dǎo)賓語從句，并在從句中作主語。whichever與whatever的區(qū)別，類似于which與what，有范圍用which，無范圍才用what。6.Itsuddenlyoccurredtohim318.Itdoesn’tmatterifyoupaybycashorcreditcardinthisstore.if→whether

因whether...or…(不管……還是……)是固定搭配。9.Ourteachersalwaystellustobelieveinthatwhatwedoandwhoweareifwewanttosucceed.去掉that

因句中已有連接代詞what引導(dǎo)賓語從句并在從句中作do的賓語了。8.Itdoesn’tmatterifyoupa3210.Whenthenewscamehowthewarbrokeout,hedecidedtoserveinthear
