间接引语从句的从句
His father said to him,"Don't leave the window open when you are sleeping at night."改间接时when he is还是was sleeping

要改成when he is。主语是His father,如果是 you were sleeping ,恐怕意思就不好理解了。

1. 答案:
His father told him not to leave the window open when he (was sleeping) at night.
2. 解释:
变间接引语时,其所含的从句的时态一般要和主句一起变化,以和主句时态保持一致.除非它是一个事实或真理.
