probably,possibly,may的用法区别是什么呀

possible“或许；也许”,所指的可能性较小,为加强语气,可与can或could连用；
与may连用,表示的可能性更小.例如： 
It may possibly be true．也许是真的. 
Please call me as soon as you possibly can．请尽快给我打电话. 
Could you possibly tell me the answer﹖你能告诉我这个答案吗?
probably“很有可能；十之八九”,其语义较强,可能性较大.在否定句中,probably不能紧跟在否定词之后.例如： 
It will probably be fine tomorrow．明天大概会是晴天. 
译：她大概不会来这里. 
正：Probably she won’t come here． 
正：She probably won’t come here． 
正：She won’t come here probably． 
误：She won’t probably come here．
may 是情态动词,后接动词原形
