单项选择（时态）
As far as we know,the train to Guangzhou ___ at nine thirty,but it ___ at nint forty.
A.leaves ; doesn't turn up
B.leaves ; hasn't turn up
C.has left ; turns up
D will leave ; doesn't turn up
第一空不用说.第二空,凭语感,感觉选B,但不知道具体的时态判断方法,况且有下面的疑问：
1、现在完成时能不能和表示时间点的时间状语一起使用?
2、我们知道,有时一般现在时可以表示将来发生的动作,也就是代替一般将来时.那以此类推,现在完成时能不能表示将来完成时?

其实我不怎么理解你的意思
我选B 原因如下
一.火车的时间点是一个常识吧肯定不会变的和谚语有点类似就是陈述一般事实所以用一般时态
第二个空为什么用完成时呢因为两点
第一点根据翻译就是但是到现在已经九点四十了车还没来相当于有个yet 可以感受到么
第二点和你说的差不多语感吧
所以你说的1 是成立的可以
你说的2 我也不知道有没有或许是才疏学浅我大学毕业了还没听过你类推的这个说法
