kEEp sB BEing DonE和 kEEp sB DonE有什么区别?As...

有区别, 都是被动,而is being done更表示正在被。。。 be being done 被动语态的进行时。 例: A lot of work is being dealt with. 很多工作正在被处理。

Have/Has been done 与Have/Has done 的区别前者是被动,后者是主动 给你举个例子吧: 比如说:我已经完成了任务,可以说:I have finished the task.这是主动 如果说任务已经被完成了,你可以说:The task has been finished
