have been keeping doing 为什么错了
是因为have been后面不能加状态么

这个一般表示正在发生的状态,been和keep在这里的作用是一样的,所以可以用have been/kept dong sth表示现在进行完成时

have been keeping doing 为什么错了 how long have u been keeping doing that / how long have u ke have been doing 为什么还有 have been dead have been doing sth have been done 和 have been doing will have been doing和have been doing的区别 have been doing 的用法, what have you been doing have been doing是什么时态? what you have been doing have been doing 神马意思? has been doing have been done区别
