一道关于动词时态的英语题,详情见内~
My sisiter has just arrived here,but in fact I didn't know until this morning she ____________to see me
A.will come
B.was coming
C.came
D.had been coming

也可使用would come, 过去进行时用在这里表达过去计划将要发生的事。你说这话时,姐已经到了。

我觉得应该是c

this morning 表示的就是过去式,而until是一直到什么时候
所以要用过去进行时.
用been doing sth.
懂了吗

我个人觉得应该选C,如果答案是B的话,中心放在know 和 come上面吗?伴随状态,强调来的时候我还不知道。
