引导的宾语从句的用法，并在语境中准确运用。能够在较复杂的语篇语境中正确使用由that,whether和if

引导的宾语从句。Ibelieveyou.IbelieveIcanfly.(that)主谓宾从句代词Ibelieve(that)Icanfly.宾语从句关联词Ibelieve(that)Icantouchthesky.

宾语从句动词、介词后的句子就是宾语从句that无实际含义，常常可以省略宾语从句在复合句中，充当宾语的句子，这个句子叫作宾语从句。宾语从句三要素：关联词、语序、时态。一、关联词引导宾语从句的常见关联词有that、if、whether、what、who、where、why和how等。1.当宾语从句具有陈述意义时，用that引导。2.that只起连接作用，没有实际意义，在从句中不充当成分，因此常可省略。e.g.Ibelieve(that)readingisimportantforlearning.that3.that不可省略①在并列宾语从句中，第二个that不可省略。Hesaid(that)helikedmathsandthathewantedtobeamathsteacher.他说他喜欢数学，想成为一名数学老师。②当that从句是双宾语中的直接宾语时，that不可省略EllatellsmethatthissentenceiscorrectinEnglish.4.当主语是I，think、believe、expect、guess、suppose等表示“认为，猜测”意义的动词后跟that引导的宾语从句的否定式时，其从句谓语动词不用否定形式，而将否定式在主句中表现出来，表达从句的否定意义。例句：Idon’tthinkwehavemet.我想我们没见过面吧。Iwonderif/whetheryoucouldhelpme.Iwanttoknowif/whetheryoureadEnglishbooksoutsideclass.1.当宾语从句具有一般疑问含义时，用if或whether引导，意为“是否”2.whether或if在从句中不充当任何成分，但不可省略。if/whether只用whether，不用if引导的情况：1)在介词后面e.g.I’mthinkingofwhetherweshouldgotoseethefilm.2)与ornot直接连用e.g.Idon’tknowwhetherornottheycangetthereontime.3)todo后面只能用whetherIcan’tdecidewhethertogoorstay.我不能决定是走还是留。一般来说，在宾语从句中if与whether可以互换使用。但有时，两者不能互换。1.Idon’tknowwhether/ifshewillgoto

hiscathaddied.3.Doyouknowif/whetherLucywillgoto

Beijingtohaveameetingtomorrow?二、语序无论主句是陈述句还是疑问句，也无论主从句间是什么引导词，宾语从句一律用陈述语序：引导词+主语+谓语+其他。Iknow(that)Jackisahard-workingstudent.Iknow(that)hewilltaketheexam.Jennyknowsthemanwasflyingakiteatthattime.宾语从句的时态一般受主句时态的影响。1.主句：一般现在时，宾语从句：任意时态（根据句意）三、时态Lindadidn’tsayifherauntwasstillwiththem.Dadtoldmethatthesunrisesintheeast.Tomtoldhissonthatleavesturnyellowinautumn.2.当主句是一般过去时，宾语从句：相应的过去时态。3.当从句表示的是客观真理或自然现象等时，一般不受主句时态的限制，用一般现在时。2.Shesaidthattheearth________aroundthesun.A.traveled B.travels C.travel1.—Excuseme,doyouknow________?Thebushasjustleft.—Yes.Thenextbuswillarriveinhalfanhour.A.howIcangettothebusstation B.iftherewillbeanotherbus C.howmuchabusticketcosts4.—Doyouknow________?—Yes,there’sonehere.It’sinthestore.A.whomheistalkingwith B.whenIcangettothehotelC.howtousethemachine D.ifthere’sarestroomaroundhere3.—Alice,I
