用一个句子作宾语，这个句子就是宾语从句。宾语从句的三大考点是时态、语序和引导词。

15-3 宾语从句的语序

当宾语从句是疑问句时，要用陈述句语序。如：

He asked me when we would start out the next day.他问我第二天什么时候出发。

Did you find out where she lost her car？你查出了她在哪里丢的车吗？

（误）I don't know where has she gone.我不知道她去哪里了。

（误）Do you know what is he doing？你知道他在干什么吗？

（正）Do you know what he is doing？你知道他在干什么吗？

（误）I don't know how does he go to school.我不知道他怎样上学。
