perhaps也许;是也许如此、也许不如此的意思,大体和possibly同义
probably大概;肯定的成分较大,是most likely的意思
possibly或者;常和can, may must等情态动词连用,比probably语气弱得多
maybe或许;比perhaps普通,但不够庄重
possible是形容词,故此处用其副词形式与其它表“也许”的副词相比。
Perhaps the letter will come today. 或许那封信今天能到。
It will probably rain. 天很可能要下雨了。
I'll do all I possibly can. 我会做我可能做到的事。
It's clouding up. Maybe it'll rain this afternoon.天阴上来了, 今天下午也许有雨。
在表示“也许”、“大概”的副词中,还有一个,即likely:
likely或许;通常与most, very连用,如:
Most likely she is over thirty.她也许已经过了30了。
may be是“可能是”,后接表语。
My answer may be correct.我的回答可能是正确的。
