3. 引导宾语从句的连接词when和where

宾语从句的语序
宾语从句的语序：在复合句中，宾语从句部分要用陈述语序。
(1) 陈述句作由that引导的宾语从句时，语序不用调整。
(2) 一般疑问句作宾语从句时，其结构为whether / if +陈述句。原一般疑问句的主语前如果是助动词do / does / did，应去掉，谓语动词应改为其相应的形式;原一般疑问句的主语前如果是don’t / doesn’t / didn’t，则直接将其放到主语之后;原一般疑问句的主语前如果是be 动词、情态动词或其他助动词，则应将其放到主语之后。如：
Does he like apples? I don’t know. ----- I don’t know whether he likes apples.
He asks: Is Tom a per? ----- He asks whether Tom is a driver.
(3) 特殊疑问句作宾语从句时， 如果疑问词作主语或主语的定语，其语序不用变化;如果疑问词充当其他句子成分，则宾语从句的结构为连接代词 / 连接副词+陈述句。如：
Who can answer the question? I want to know. ----- I want to know who can answer the question.
Whose book is on the desk? We all know. ----- We all know whose book is on the desk.
When will they arrive? Please tell us. ----- Please tell us when they will arrive.
宾语从句的引导词
