📚 Day29 知识讲解

在句子中起宾语作用的从句称为宾语从句(三大考点:1.语序2.时态3.引导词)
语
序
陈述语序(主语+谓语+其它)
Where will he go?→I wonder where he will go.
时
态
①主现从不限:当宾语从句的主句是现在类时态时,从句可以是任何时态
②主过从必过:当宾语从句的主句是过去类的时态时,从句使用相应的过去时态
③真理永一现:当从句是客观事实或真理时,只能使用一般现在时
引
导
词
①that引导宾从(无意义,不作句子成分,可省略)
I know (that) you are a good student.
②if / whether 引导宾从(意为“是否”,不作句子成分,不可省略)
【注意】只能用whether 的情况:介词之后&与or not 连用时
Tom asks me if/ whether Jerry likes eating cheese.
Tom asks me whether Jerry likes eating cheese or not.
③关系代词(who/ whom/ whose/ which/ what)引导宾从(有意义,作主语或宾语,不可省)
I don't know what they are going to do.
④关系副词(when/ where/ why/ how)引导宾从(有意义,作状语,不可省略)
I wonder where she goes.
