有其自身旳意義。此外，我們可以把what解釋為：the＋名詞＋that/which。3．whether和if旳運用(誤)Ifwe'llholdthepartyhasnotbeendecidedyet.(正)Whetherwe'llholdthepartyhasnotbeendecidedyet.whether合用于任何狀況；if(作“與否”講)僅限于動詞賓語從句中，但discuss,decide等動詞后旳賓語從句除外。4．連接詞旳使用易受漢語干擾(誤)ThereasonwhyIwaslateisbecauseIwastrappedinthetrafficjam.(正)ThereasonwhyIwaslateisthatIwastrappedinthetrafficjam.第一句通過提取簡化可得出：Thereasonisbecause...在英語中顯然導致了反復現象。〔考點集訓〕Ⅰ.單句語法填空1．__How__weunderstandthingshasalottodowithwhatwefeel.2．Ashipinharborissafe，butthat'snot__what__shipsarebuiltfor.3．—IsittruethatMikerefusedanofferfromYaleUniversityyesterday?—Yeah，butIhavenoidea__why__hedidit；that'soneofhisfavoriteuniversities.4．Thecompaniesareworkingtogethertocreate__what__theyhopewillbethebestmeansoftransportinthe21stcentury.5．Itdoesn'tmatter__whether__youturnrightorleftatthecrossing—bothroadsleadtothepark.6．Asmanyasfivecoursesareprovided,andyouarefreetochoose__whichever__suitsyoubest.7．Jerrydidnotregretgivingthecommentbutfelt__that__hecouldhaveexpresseditdifferently.8．Thenoticecamearoundtwointheafternoon__that__themeetingwouldbepostponed.9．Afarmeronceorganizedacompetitionbetweenhisdogandhisrabbit.Hedugaholeinoneofhisbiggestfields，andhidacarrotandaboneinit.Hewantedtosee__which__animalwouldfindthemfirst.10．Itcanbereallyupsettryingtoaskforsomethinginastoreortotellthetaxidriver__where__youaregoing.Ⅱ.單句改錯(每題僅有1處錯誤)1．ThatBarbaraJonesofferstoherfansishonestyandhappiness.__That→What__2．Itwasneverclearwhetherthemanhadn'treportedtheaccidentsooner.__whether→why__3．Itisstillunderdiscussioniftheoldbusstationshouldbereplacedwithamodernhotelornot.__if→whether__4．Hesaidhowalovelygirlshewas.__how→what__5．Thevillagershavealreadyknownwhichwe'lldoistorebuildthebridge.__which→what__6．Whatheshoulddoishestaysathomeandwaitsforhismotherfromwork.__is后加that__7．Thereasonwhyhewaslatewasbecausehisbikewentwrong.__because→that__8．I'dliketostartmyownbusiness—that'showI'ddoifIhadmoney.__how→what__9．Hecamelate.Thatwashegotuplate.__was后加because__10．Thequestionthatwhysomanypeoplewouldchoosetoliveinthecountrysidebuttoworkinthecityisstillunderdiscussion.__去掉that__Ⅲ.語法填空(名詞性從句專練)1．__What__worriesmyclassmateMaryalotthesedaysis2.__that__sheputsontoomuchweightandsheisfrequentlyill.Shehassomedoubts3.__whether__sheeatstoomuchfastfoodhighinfatorsugar.Also,withtheCollegeEntranceExaminationapproaching,shebecomesmorestressfulandshecan'tsleepwellthesedays.Maybe
