what is different between "he is going to die" and "he is dying".

问题描述:

what is different between "he is going to die" and "he is dying".

dying的状态表示奄奄一息.
He is going to die虽然也是说他要死了,但是离死亡间隔比He is dying远.
举个例子癌症晚期可以说He is going to die.
死前几小时神马的躺在床上可以说He is dying.
这是我的理解.那中国人的口头语 我要死了 用哪个啊?你是说生理上吗?临死前应该是I am dying.
