请教问题

Of all the possible disasters that threaten American agriculture, the possibility of an adverse change in climate is maybe the more difficult for analysis.

为什么maybe should be replaced by porbably

谢谢大侠赐教

刘苏说maybe太过于口语化

应该尽量避免

书面语中表可能性尽量用probably

顶，2楼的是不是也在新东方上语法课啊。GMAT考试中应多用书面语，比如probably,perhaps代替maybe
