一、宾语从句常见的类型：1.动词的宾语从句2.介词的宾语从句3.形容词的宾语从句1.作动词的宾语(1)由that引导的宾语从句(that通常可以省略),Iheardthatbejoinedthearmy.(2)由what,whether(if)引导的宾语从句，例如：Shedidnotknowwhathadhappened.Iwonderwhetheryoucanchangethisnoteforme.(3)动词＋间接宾语＋宾语从句。例如：Shetoldmethatshewouldacceptmyinvitation.2.作介词的宾语，Oursuccessdependsuponhowwellwecancooperatewithoneanother.3.作形容词的宾语Iamafraid(that)I’vemadeamistake.注意：that引导的从句常跟在下列形容词后作宾语：anxious,aware,certain,confident,convinced,determined,glad,proud,surprised,worried,sorry,thankful,ashamed,disappointed,annoyed,pleased,hurt,satisfied,content等。4.it可以作为形式宾语it不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that从句则放在句尾，特别是在带复合宾语的句子中。Wehearditthatshewouldgetmarriednextmonth.5.否定的转移若主句谓语动词为think,consider,suppose,believe,expect,fancy,guess,imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。Idon’tthinkthisdressfitsyouwell.我认为这件衣服不适合你穿。引导宾语从句的词有：1.连词that(在口语中that常可省略）HeknowsthatJimwillworkhard.2.连接代词who,whom,which等Doyouknowwho(whom)theyarewaitingfor?3.连接副词when,where,how,whyCouldyoutellmehowwecangettothestation?4.whether和if都有“是否”的意思，一般情况下两者可以换用，但在介词之后、不定式之前、与ornot连用、在句首或在引导表语从句同位语从句时，只能用whether。Iwanttoknowif/whetherthenewsistrue.Hedoesn'tknowwhethertostayornot.动词doubt用在疑问句或否定句时，其后宾语从句常用that作连接词；用在肯定句时，连接词用whether或if皆可，而不用that。Doyoudoubtthathewillwin?Idon'tdoubtthatyourpropositioniswrong.Hedoubtswhether/ifIknowit.表语从句一个从句在复合句中作主句的表语，这个从句就叫作表语从句。Theproblemisthatmillionsofpeopledieofillnessescausedbysmoking.Thequestionremainswhetherwecanwinthepeople.1.从属连词that（一般不省略为好），whether（不用if），asif（though）等引导的表语从句。Thereason(why)shehasn'tcomeisthat(此处不可用because)shehastotakehermothertoahospital.她没来是因为她必须送母亲去医院。2.连接代词what,which,who,whom,whose等引导的表语从句。ThisiswhatIwanttosay.这就是我想说的。3.连接副词when,where,how,why等引导的表语从句。Thisishowweovercomethedifficulties.这就是我们克服困难的方法。
