if/whether引导的宾语从句

一、由ifwhether引导的宾语从句。if/whether“是否,说明对陈述的事物不明确或不清楚。

常用在ask,wonder,can(could)youtellme等后,二者通常可以互换。

例如:Lilyaskedif/whethershelikedit.莉莉问她是否喜欢它。

Iwanttoknowif(whether)helivesthere.我想知道他是否住在这儿。 Heaskedmewhether(if)Icouldhelphim.他问我是否可以帮助他。 小试牛刀:1Mr.Dingasked.Couldhecomeatseven?

2Shewantedtoknow.Didyouhaveagoodtime?

二、只能用whether不能用if的情况

1)在介词后面:

例如:I’mthinkingofwhetherweshouldgofishing. Weareworriedaboutwhetheritwillraintomorrow. 2)在动词不定式前(whethertodosth.) 例如:Theyaskedmewhethertogoskating. 3)当与ornot连用,或提出两种选择时: 例如:Idon’tknowwhetherhe’sfreeornot. MaryaskedwhetherIwasdoingmyhomeworkornot. 4)宾语从句提前时:

例如:Whetherthisistrueornot,Ican’tsay. 小试牛刀:请用ifwhether填空 1.Iaskedher___________shehadabike. 2.Wereworriedabout___________heissafe. 3.Iwonder___________heiswell.

4.Idontknow___________ornotheiswell. 5.Idontknow___________togo.



三、宾语从句的语序:引导词+主语+谓语+其他成分

例如:Ithinkthatwecanbegoodfriends. Ican’trememberifIpostedtheletter. Mayweaskwhatyouaredoing?

四、特殊的宾语从句———间接引语

当直接引语是一般疑问句,改为间接引语时,连接代词用ifwhether,而引述选择疑问句时用whether,引述动词用ask,没有间接宾语的可以加一个间接宾语me,him等。

例如:ShesaidtoTom,“Canyouhelpme?”→SheaskedTomif/whetherhecouldhelpher. Sheasked,“Isthisbookyoursorhis?”→Sheaskedmewhetherthatbookwasmineorhis.
