專題04 名詞性從句講義 高考英語語法

專題03名詞性從句講義高中英語語法定義名詞性從句相當于名詞，可分別作主句的主語、表語、賓語和同位語。因此，名詞性從句廳分為主語從句、表語從句、賓語從句和同位從句。連接詞連接代詞：what,who,whom,whose,which連接副詞：when,where,why,how從屬連詞：if,whether,that.注意：1.連接代詞與連接副詞在句中不再是疑問句，因而從句中謂語不用疑問式。2.連接詞whether和if（是否），在從句中不充當句子成分，只起連接作用,如果表達是否，盡量選擇whether。3.根據(jù)句子意思，如果連接代詞與連接副詞，whether、if都用不上時，才用that作連接詞（that本身無任何含義）。各從句的詳解主語從句主語從句在復合句作主語。Whathesaidisnottrue.Don’ttrusthim.Howhepersuadedthemanagertochangetheplanisinterestingtousall.that引導主語從句時，不能省略。Thathewonthematchmadeusexcited.主語從句過長時，可以用it來做形式主語，主語從句放后面。Itisreportedthattheweatherwillbesunnynextweek.Itdoesn’tmattersomuchwhetheryouwillcomeornot.賓語從句在句中擔當賓語的從句叫賓語從句。一般位于及物動詞或者介詞之后。HesaidthathewouldgobacktotheU.S.soon.Scientistshaveprovedthattheearthturnsaroundthesun.表語從句表語從句在復合句中作表語，位于系動詞之后。 e.g.Thequestionwaswhocouldsolvetheprobleminourcompany. 2、引導表語從句的連接詞that有時可省去。Mythoughtis(that)wecanemploymoreworkersinthebusyperiod.同位語從句同位語從句在句中作某一名詞的同位語，一般位于該名詞（如：news,fact,idea,suggestion,promise等）之后，解釋說明該名詞的具體內(nèi)容。Thenewsthattheyhadwonthegamesoonspreadoverthewholeschool.Thefact____________shehadnotsaidanythingatthemeetingsurprisedeverybody.注意：定語從句和同位語從句的區(qū)分：詞類上的不同同位語從句的解釋說明的名詞一般為抽象名詞，而定語從句的先行詞名詞、代詞以及句子均可。Whiletheyarerarenorthof88°,thereisevidencethattheyrangeallthewayacrosstheArctic,andasfarsouthasJamesBayinCanada.(同位語從句)DoyouremembertheteacherwhotaughtusEnglishatmiddleschool?（定語從句）連接詞的不同定語從句中的連接詞無意義，要充當成分，同位語的連接詞除that以外，均有意義Thetruththattheearthturnsaroundthesunisknowntoall.Asisknowntoall,theearthturnsaroundthesun從句的功能不同定語從句的功能是修飾限定，同位語的功能為解釋說明Thenewsthatourteamhadwonthegamewastrue.Thenewsthathetoldmeyesterdaywastrue.課堂練習用名詞性從句的連詞填空Iamveryinterestedin____________hehasimprovedhispronunciationinsuchashorttime.Newscamefromtheschooloffice________WangLihadbeenadmittedtoBeijingUniversity.Haveyoudetermined______youshouldbuy,anAppleorSamsungcellphone?Whatthedoctorsreallydoubtis______mymotherwillrecoverfromtheseriousillnesssoon.Sheaskedme________Ihadreturnedthebookstothelibrary,andIadmittedthatIhadn'tIaskedhim________hisfatherhaddonesothathebecamesuchagoodperson.Successpartiallydependson________youhavethepatiencetodosimplethingsperfectly.ThereweresomanybrightyellowBeta400scarsinthecar-parkthathedidnotknowwashiscar.
