possibly; probably; perhaps; maybe
这几个副词都有“可能”的意思，用法如下：
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．
perhaps“或许”，含有“可能这样，也可能不这样”之意，其含义和用法与maybe一样，多用于口语。maybe多用于美国英语。在这几个单词中，语义最强的是probably，其次是perhaps和maybe，最弱的是possibly。例如：
Perhaps we will be late for work．或许我们上班会迟到。
Perhaps we’d better take a bus．也许我们最好乘公共汽车。
