Theydidn’tknowwhetherTomcouldcomebackornot.②“是否”可与or(not)连用。可引导主语从句、表语从句、宾语从句、步状语从句等，引导主语从句时可置于句首。whether引导主语从句，不能与if替换。

e.g.whetherornottheywouldsupportuswasaquestion.③If：“是否”，引导宾语从句。一般不与or(not)连用。“如果”，引导条件状语从句。

※if和whether的用法及区别一般来说，在宾语从句中，if与whether可以互换使用，但在特殊情况下，if与whether是不能互换的。(1)whether之后紧跟ornot时，不可与if互换。e.g.Nobodyknowswhetherornotitwillraintomorrow.(2)在介词后只能用whether。e.g.Theboyworriesaboutwhetherhehasbrokenhismother’sheart.(3)与动词不定式连用时，只能用whether。e.g.Ican’tdecidewhethertogoortostay.用if/whether填空1.Itdependson

当宾语从句说明的是客观存在的事实或者是客观存在的真理时，就不用受到主句时态的限制，仍是用一般现在时态。主句时态从句时态一般现在时、一般将来时、祈使句时根据句意的需要用任意一种时态一般过去时与原句相对应的过去的时态客观事实、真理、自然现象、名言警句、谚语等一律用一般现在时2六.宾语从句的语序无论主句是陈述句还是疑问句，宾语从句都是运用陈述句的语序，即是“主语在前，谓语在后”的顺序。►DannysaysthathewilllearnEnglish.►Doyouknowwherehecamefrom?►PleasetellmehowIcangettothebusstation.宾语从句三要素引导词that+陈述句if／whether+一般疑问句特殊疑问词+特殊疑问句时态主句为一般现在时主句为一般过去时一般过去时过去将来时过去进行时过去完成时语序宾语从句的语序都为陈述句语序从句客观真理时态不变从句可为任何时态1．Idon’tknow_________hewillcometomorrow．_________hecomes,I’lltellyou．A．if；WhetherB．whether；WhetherC．if；ThatD．if；If2．Idon’tknow_________thedayaftertomorrow．A．whendoeshecomeB．howwillhecomeC．ifhecomesD．whetherhe’llcome3．Couldyoutellme_________thenearesthospitalis？A．whatB．howC．whetherD．where4．Couldyoutellme_________theradiowithoutanyhelp？A.howdidhemendB．whatdidhemendC．howhemendedD．whathemended5．Iwanttoknow_________．A．whomisshelookingafterB．whomsheislookingC．whomisshelookingD．whomsheislookingafter6．Doyouknowwhere_________now？A．helivesB．doesheliveC．helivedD．didhelive7．Doyouknowwhattime_________？A．thetrainleaveB．doesthetrainleaveC．willthetrainleaveD．thetrainleaves8．Idon’tknow_________．Canyoutellme,please？A．howthetwoplayersareoldB．howoldarethetwoplayersC．thetwoplayersarehowoldD．howoldthetwoplayersare9．Thesmallchildrendon’tknow.A．whatistheirstockingsinB
