Do you know when the train to leave?与Do you know the train when to leave?

问题描述:

Do you know when the train to leave?与Do you know the train when to leave?

意思一样!不过第一个的主语是You,第二个主语是The train!

都是错的.
应该是:
Do you know when the train will leave?
或者:
Do you know when the train is leaving?

翻译: 你知道火车什么时候离站吗?
