【例句】1.Ithink(that)mathisdifficult.Shesaid(that)shewouldleaveanoteonthedesk.【结论】

陈述句作宾语时，宾语从句用that引导。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。(1)由that引导的宾语从句宾语从句结构I:主语+谓语动词+that+宾从(肯定句、否定句)I

thattheWaterFestivalisnotfun.主语谓语宾语从句(否定句)Billthinks

thattheraceswereinterestingtowatch.宾语从句(肯定句)主语谓语宾语从句的引导词that，它在句中无词义，在从句中不做成分，在非正式文体中可以省略(2)由if/whether引导的宾语从句宾语从句结构II:主语+谓语动词+whether/if+宾从(一般疑问句，陈述语序)宾语从句的连词whether/if

表示“是否”，不可省略由于if和whether连接的句子在语义上是一般疑问句或选择疑问句，要注意把从句语序改为陈述句语序。主+谓把下面两个句子改为含有宾语从句的复合句。1.IsJimagoodstudent?Idon'tknow.2.DoesKategetupearly?Doyouknow?Idon'tknowwhether/ifJimisagoodstudent..Doyouknowwhether/if

Kategetsupearly?练一练一般来说，在宾语从句中if与whether可以互换使用。但在特殊情况下，两者不能互换。只能用whether，不能用if引导的情况：1)在介词的后面e.g.I’mthinkingofwhetherweshouldgotoseethefilm.2)与ornot直接连用

e.g.Idon’tknowwhetherornottheycangetthereontime.►Idon’tknowwhetherornothewillcome.如果ornot放在whether所引导的从句句尾，可用if替换。►Idon’tknowwhether/ifhewillcomeornot.注意whether和if的使用区别a.当whether后紧跟ornot时，不用if.b.介词后面的宾语从句不能用if.►IworryaboutwhetherIhurtherfeelings.►HeaskedmewhetherIwantedtogotherebytrainorbybus.c.在强调任意选择时，用whether…or，此时不用if替换whether。►WhetherhewillcomeIamnotsure.注意whether和if的使用区别d.虽引导宾语从句，但为了强调宾语部分，也可把从句放在句首，此时只用whether不用if。e.句子中有if引导的条件句，如再有表示“是否”的宾语从句，用whether不用if。►HeaskedmewhetherI’dmovetoNewYorkifIgotthejob.f.如果宾语从句为否定句时，则只用if不用whether。►Idon’tknowifitwon'traintomorrow.“Doyoulikethesong?”sheasks.Sheaskswhether/ifIlikethesong.Tomsaid.Heisreadingabook.

Tomsaidthathewasreadingabook.一般疑问句陈述句(人称变化)陈述句观察与发现总结：宾语从句一定用陈述语句。即“引导词+主语+谓语+其他成分”WouldyoupleasetellmeDoyoustillrememberIdon’tknowLet’smatch,talkandthink.WhatshouldIdo?Whenisthebooksale?Whydidyoucomehere?WheredoyouhaveyourEnglishlessons?例：Wouldyoupleasetellmewhenthebooksaleis?3宾语从句用特殊疑问词做引导词用陈述语序宾语从句的语序注意观察下面句子的变化一般疑问句陈述句一般疑问句陈述句Doyouknow(whether)helikessports?Heasks(whether)theywillplaybasketballafterschool.宾语从句都是运用陈述句的语序，即“主语在前谓语在后”的顺序宾语从句的时态►DannysaysthathewilllearnEnglish.

►Doyouknowwherehecamefrom?

►PleasetellmehowIcangettothebusstation.比较主句和从句的时态变化一般现在时一般将来时一般现在时一般过去时一般现在时一般现在时若主句是一般现在时，从句用任何所需时态。主现从随便HewillgotoHongKong.Heissick.Heisreadingabook.Hehasfinishedhiswork.HesaidHehadfinishedhiswork.HewouldgotoHongKong.Hewassick.Hewasreadingabook.

当主句是一般过去时的时候，宾语从句必须运用相应的过去的某一种时态，从而达到主句和从句的相互一致。主句从句主过从四过！宾语从句的时态一般现在时→一般过去时现在进行时→过去进行时一般将来时→过去将来时现在完成时→过去完成时一般过去时→过去完成时若主句是一般过去时，从句则用过去相关的时态主过从必过Didthetrainleave?Shedidn’tknow.→Shedidn’tknowif/whetherthetrainhadleft.宾语从句的时态客观真理永不变1.Theteachertoldusthattheearthmovesaroundthesun.2.Hesaidtomelighttravelsfasterthansound.老师告诉我们地球绕着太阳转他对我说光比声音传播的更快。一般过去时一般现在时一般过去时一般现在时从句是客观真理是用一般现在时态当堂检测2______语序
