在句子中起宾语作用的从句叫做宾语从句。

WeknowMrGreenteachesEnglish.Sheaskediftheseanswerswereright.二、宾语从句三要素语序时态连接词（桥）宾语从句的语序宾语从句的语序应为陈述句的语序。例如：

Ihear(that)_______________________

.physics、easy、isn’tIthink(that)__________________

.willlike、you、this、schoolCanyoutellmehow__________________?

I、to、get、canzooPleasetellmewhen__________________.

you、themeeting、had.1.Ihear(that)_______________________.2.Hesaid(that)______________________.3.Theteachertoldus(that)_______________________________.hewillbebackinanhourhemissedusverymuch

theearthmoves由that引导的宾语从句注：that在句中无词汇意义，在从句中不充当成分，在口语当中往往省略。aroundthesunObjectclauseswiththat宾语从句的连接词Ⅰ.if和whether引导宾语从句时，作“是否”讲，一般情

况下，二者没有区别，可以换用。但if常用于口语中，whether比较正式。如：

Millieaskedif/whetherhelikedthissweater.

米莉问他是否喜欢这件羊毛衫.Objectclauseswithifandwhether由if/whether引导的宾语从句Ⅱ.if和whether引导宾语从句时，要注意宾语从句三要素，

即连词、语序和时态。由于if和whether连接的是一般

疑问句，因此要注意把从句语序改为陈述句语序。如：

DoesMrZhaoliveinRoom208?Couldyoutellme?→Couldyoutellmeif/whetherMrZhaolivesinRoom208?Ⅲ.if和whether的区别二者在下列几种情况下不能换用：1.宾语从句置于句首表示强调时，应用whether，不用if。如：

Whetherthisistrueornot,Ican’tsay.

这是否对，我不能说。3.与动词不定式连用时，只能用whether。如：

Shecan’tdecidewhethertogotoAmerica.

她不能决定是否去美国。4.从句作介词宾语时，只能用whether。如：

IworryaboutwhetherIhurtherfeeling.

我担心是否伤了她的感情。1.若主句是一般现在时，从句用任何所需时态。如：

Hewantstoknowif/whethertheyhadagoodjourneyhome.

他想知道他们回家旅途是否愉快。宾语从句中的时态【练一练】用that，if，whether填空。

thatif/whetherwhetherthatwhether1.若主句是一般现在时，从句用任何所需时态。如：

Hewantstoknowif/whethertheyhadagoodjourneyhome.

他想知道他们回家旅途是否愉快。宾语从句中的时态Idon’tthink(that)you________(be)right.Pleasetelluswherehe________(be).CanyoutellmehowIcan________(get)totherailwaystation?Haveatry.2.若主句是一般过去时，从句则用跟过去相关的时态。

即一般现在时变为一般过去时、现在进行时变为过去

进行时、一般将来时为过去将来时、现在完成时态变

为过去完成时。

Didthetrainleave?Shedidn’tknow.→Shedidn’tknowif/whetherthetrainhadleft.主语是过去式从句时态改成相应的过去时态一般现在时一般将来时一般过去时现在完成时现在进行时一般过去时过去将来时过去完成时过去完成时过去进行时Heaskedwhattimeit________(be).Hetoldmethathe________(be)preparingforthesportsmeet.Heaskedifyou________(have)writtentoPeter.Hesaidthathe________(will)gobacktotheU.S.soon.Haveatry.3.从句表达的是客观真理,用一般现在时注意：Theteachertoldusthatlighttravelsfasterthansound.1）OurteachersaidthatJanuary________(be)thefirstmonthoftheyear.2）Scientistshaveprovedthattheearth________(turn)aroundthesun.主句时态从句时态一般现在时、一般将来时、祈使句时

一般过去时客观事实、真理、自然现象、名言警句、谚语等

根据句意的需要用任意一种时态与原句相对应的过去的时态一律用一般现在时4aWritesentencesusingthewordsgiven.IbelievethatWaterFestivalisthemost
