she ask him whether he was coming back for lunch 为什么用was coming
问题描述：
she ask him whether he was coming back for lunch 为什么用was coming
答
过去将来时
就是她问他要不要来吃饭
对于“她问”这个动作 来吃饭后发生 所以用将来时
答
因为主句是过去时， 从句用过去将来。 was coming 就是用come用进行时表将来。
答
这个句子一般有两句表达方式:
She asked him whether he was coming back for lunch.
过去进行时表将来.
She asked him whether he would come back for lunch.
过去将来时.
答
这是个错句子哎...
