It is still difficult to tell who will win the next match.现在还很难说谁将在下一场比赛中取胜
It is still difficult to tell who will win the next match.现在还很难说谁将在下一场比赛中取胜 这句话中to可以去掉吗?为什么?

不可以,这里的不定式短语to tell who will win the next match,为句子中的真正主语,前面的it只是个形式主语.楼上那几个人说的都对吗?一楼的解释得不清楚。其实,在这里最关键的就是:动词作主语时,不是用to do就是用doing。
