1、疑问词引导的宾语从句当宾语从句是特殊疑问句时，不需加引导词，特殊疑问词就是引导词，意思也是疑问词的意思。疑问代词：who谁（主格）,whom谁（宾格）,whose谁的,what什么,which哪一个CanyoutellmewhatIshoulddo?疑问副词：when什么时候,where哪里,how如何、怎么样,why为什么Iwanttoknowwhyyouarelateforschool.语序语序：陈述句语序即：主句+疑问词+主语+谓语+其他（主语+谓语）从句Couldyoutellmewhereweshouldgonext?主句疑问词

2、主语谓语注意：主句中could提问表委婉语气，不是表示过去时态。特殊情况当疑问代词who,what在句中做主语，该特殊疑问句本身就是陈述句语序，变为宾语从句时，语序不必调整.1Who(主)cananswerthequestion?Theteacherasked.→Theteacheraskedwhocananswerthequestion.2WhatisthematterwithKate?→Heaskswhat'sthematterwithKate.还有：What'swrongwithyou?What'sup?What'sthetroub

3、lewithyou?Whathappenedtohim?时态1、当主句是一般现在时，从句根据句意任何时态。2、当主句是一般过去时，从句用相应的过去时态。3、当从句说的是客观真理、自然现象或永恒不变的规律时，不受主句时态影响，用一般现在时。可以简化含有宾语从句的复合句在一定条件下可以转化成简单句当主句的主语或宾语与从句的主语一致时，则宾语从句可变成“疑问词+todo（宾语从句中的谓语动词）"的结构。Idon'tknowwhatIshouldsay.=Idon'tknowwhattosay.CanyoutellmewhereIshouldgo
