请问各位这三句: Late-breaking news! A major earthquake [_______] in southern california. 为什么这句[]是用has just occurred而不能用occurred, 地震不是开始和结束都在过去吗? I admit that I have gotten older since I last saw you, but with any luck at all, I [am also getting] wiser. []中为什么是用现在进行式呢? 还会继续变得更聪明? Joe North passed away? I'm sorry to hear that. I [knew] hime well when we were in college together. (持续)到现在还是觉得他人是安好的,[]用现在完成式也可以吧?
