  likely,possible与probable

  likely是常用词,指从表面痕迹来看很有可能。主语既可以是人也可以是物。可以说sb/sth be likely to do,但是不可以说 It is likely for sb to do sth.。

  possible强调客观上有可能,但含有实际上可能性很小的意思。主语不可以是人,只能是用it作形式主语。构成It is possible for sb to do sth.。

  probable 语气比possible强,含有"很有可能,十有八九"的意思。构成It is probable for sb to do sth.。
