may,might表示可能.might比may语气缓和.Could+have+v-ed表示过去有可能或有能力做某事,而实际没做,未能实现的事.副词有maybe,possibly,perhaps,likely,probably,Maybe,可能性不大,不太正式.possibly,可能性较大。用于否定句和疑问句时表示"无论如何"之意。perhaps,较正式,可能性不大,可表示建议或要求.likely,和probably,可能性最大,但likely常用于口语中，其主语往往是人，后接不定式短语，构成belikelytodosth.结构.而后者通常不跟不定式.形容词有possible,likely,probable,其可能的语气程度如其副词形式.还有一些词也可表示可能的意思:achievable,potential,doable,feasible......
