一.possible表示客觀上潛在的可能性,也許實(shí)際發(fā)生的可能性并不大.possible一般不用表示人的詞作主語,但若真的要用表示人的詞作主語,possible后接不定式,這個(gè)不定式動(dòng)作的邏輯賓語應(yīng)是句子的主語,但此時(shí)的possible已經(jīng)轉(zhuǎn)意為“容易的”.常用結(jié)構(gòu)有：
1.It is possible（for sb）to do sth.
2.It is possible that從句.
It is possible for us to get from Beijing to Tianjin in less than an hour.
我們有可能用不到1小時(shí)的時(shí)間就可從北京到達(dá)天津.
It is possible that I might be of some use in that part of work.
在做工作的那一部分時(shí),我可能幫得上忙.
二.likely強(qiáng)調(diào)表面上看來有可能,與probable意思接近,有時(shí)可以互換,但likely常暗示從表面跡象來判斷；probable則經(jīng)過權(quán)衡正反兩方面的理由后而相信某事是真實(shí)的或大概會(huì)發(fā)生.常用結(jié)構(gòu)有：
1.主語（人或物）is likely to do sth.
2.It is likely that從句.
I”m hardly likely to finish it within a week.
我不可能在一周內(nèi)把它干完.
It is very likely that he will not agree.
他很可能不同意.
