whether/if及疑问词引导的宾语从句上一个模块中我们学习了that引导的宾语从句,本模块我们学习whether/if引导的宾语从句和疑问词引导的宾语从句。一、whether/if引导的宾语从句当一般疑问句充当句中的宾语时,用连词whether或if引导,连词在从句中不充当任何句子成分,意为“是否”,不可省略。当宾语从句中没有ornot时,whether和if都能用;但当宾语从句中有ornot时,只能用whether。另外,充当宾语从句的一般疑问句要变为陈述句语序。如:WillshegotoBeijingtomorrow?Idon’tknow.→Idon’tknowif/whethershewillgotoBeijingtomorrow.WillDavidmovetoourcityornot?Sheasked.→SheaskedwhetherDavidwillmovetoourcityornot.二、疑问词引导的宾语从句当特殊疑问句充当句中的宾语时,由原来的疑问代词what,who,which等或疑问副词when,where,how,why等作为连接词,这些词在宾语从句中充当一定的句子成分,都有各自的词义,不可省略。另外,充当宾语从句的特殊疑问句要变为陈述句语序。如:Whatishissistergoingtodo?IaskJack.→IaskJackwhathissisterisgoingtodo.WhendidshearriveinBeijing?Iwanttoknow.→IwanttoknowwhenshearrivedinBeijing.Wheredidyoubuythebeautifulscarf?Couldyoutellme?→Couldyoutellmewhereyouboughtthebeautifulscarf?三、whether/if及疑问词引导的宾语从句的时态我们在使用这两类从句的过程中,当主句的谓语动词是一般现在时的时候,宾语从句的谓语动词可根据需要使用适当的时态;当主句的谓语动词是一般过去时的时候,宾语从句的谓语动词常用相应的过去时态;但当宾语从句表述的是客观真理时,不管主句的谓语动词是何种时态,该从句须用一般现在时。如:Iwanttoknowwhether/ifyourbrotherwenttothezooyesterday.Susanaskswhether/ifshecangototheschoolaftereighto’clock.HeaskedmewhatIwasdoingatthattime.Thelittleboyaskedwhether/ifalltheplanetsgoaroundthesun.【运用】将下列汉语句子翻译成英语。1.托尼问我住在哪儿。_____________________________________2.我想知道他明天会去游泳还是不会。_____________________________________3.我想知道他姐姐是不是英语老师。_____________________________________答案【运用】1.TonyaskswhereIlive.2.Iwanttoknowwhetherhe’llgoswimmingtomorrowornot.3.Iwanttoknowif/whetherhissisterisanEnglishteacher.
