模块语法专练 whether if及疑问词引导的宾语从句1 whether if引导的宾语从句 1 whether if引导宾语从句时 意为 是否 表示不确定的概念 常位于ask see say know findout等词或短语后面 一般情况下 两者可互换 在口语中多用if 例如 Heaskedif whethertheyneededsomehelp 他问他们是否需要帮助 2 whether和if的区别 在动词不定式之前只能用whether 例如 Ican tdecidewhethertostay 我不能决定是否留下 在固定结构 whether ornot 中 只能用whether 例如 Iwanttoknowwhetherit sgoodnewsornot 我想知道它是否是个好消息 在介词后只能用whether 例如 Hisfatherisworriedaboutwhetherhemaylosehisjob 他的父亲担心他是否会失去工作 2 疑问词引导的宾语从句 1 由特殊疑问句充当宾语从句时 该从句由特殊疑问词引导 此从句要用陈述句的语序 例如 Idon tknowwhentheplaneflies 我不知道飞机什么时候起飞 2 当宾语从句由连接副词或代词when where who why which what whose等引导时 有时可以改为由 疑问词 动词不定式 构成的不定式短语 使宾语从句转化为简单句 但前提是主句的主语与从句的主语一致或主句的宾语是从句的主语 例如 CanyoutellmehowIcangettothebusstop Canyoutellmehowtogettothebusstop 你能告诉我怎样去公交车站吗 单项填空 C 1 Iwonder Yes ofcourse A wherewecanbuythepartsB howoftenyouhearformyoursisterC ifImayhaveawordwithyouD whyhearrivedlateyesterday A 2 Whatdidheaskjustnow Hewondered A iftheywouldmeetattheschoolgateB whenwouldtheystartC thattheywouldtakesomefoodD howtheywillgetthere D 3 IwondertheideatoDaming Hestilllooksangry A ifhaveyoumentionedB whathaveyoumentionedC whatyouhavementionedD ifyouhavementioned B 4 Doyouknowwewillarriveatyourhometown Thisafternoon A whyB whenC ifD where C 5 Mygrandmotheralwaysasksme A whycansheusetheiPadB howcansheusetheiPadC howshecanusetheiPadD whencansheusetheiPad 用适当的引导词填空1 CouldyoutellmehowpeoplecelebratetheDragonBoatFestivalinChina Sure Peopleusuallywatchthedragonboatracesandeatzongzi 2 I mwaitingforthemail Doyouknowwhenitwillarrive Usuallyitcomesby4 00pm 3 Excuseme Iwonderif whetherthereisabusheretogotoDowningStreet Yes BusNo 223 4 Couldyoutellmewhathesaidatthemeeting Sorry Ididn tgotothemeeting 将下列句子改为含有宾语从句的复合句 每空一词1 Whendidthetrainleave Iwantedtoknow Iwantedtoknowwhenthetrainleft 2 Aretheremanypeopleattheparty Ididn tknow Ididn tknowif whetherthereweremanypeopleattheparty 3 DoesitcostmuchmoneytoflytoBeijing Couldyoutellme Couldyoutellmeif whetheritcostsmuchmoneytoflytoBeijing 4 WhoinventedTVset Idon tknow Idon tknowwhoinventedTVset 5 Doesthegirlneedanyhelp Heaskedme Heaskedmeif whetherthegirlneededsomehelp
