Question

将下列句子改为含有宾语从句的复合句

Did it take him two hours to finish the work?Do you know.
Do you know ( ) him two hours to finish the work?

Answer 1

答案：Did it take him two hours to finish the work?Do you know.

Do you know ( whether / if it took ) him two hours to finish the work?

解析：因为前面的句子是作为从句出现，所以要用陈述句语序，和单独提出来当问题问别人是不一样的，这一点首先要明白；

其次，把疑问句变成陈述句，首先要把疑问句的倒装格式变为陈述句语序，比如did it take要变成it took。要想在陈述句中表示简单疑问句（就是用Yes和No就能回答的句子）要问问题的意思，句首加 if 就可以了。
