误It's possible to happen ...
误It's possible to be done ...
正It's possible ...
析possible本身就意味着that may happen或that can be done,故不能说It's possible to happen...或It's possible to be done...。
他认为她那天有可能回来。误He thought it was possible that she should come back that day.
正He thought it was possible that she would〔might〕 come back that day.
她可能会把我忘了吗?误Is it possible that she may have forgotten me?
正Is it possible that she can have forgotten me?
你不可能需要经济上的援助。误It is impossible that you shall need any financial support.
正It is impossible that you should need any financial support.
析it is possible that后面通常接will〔shall〕, may, would或might,很少接should或could〔can〕,因为所表示的或者就是事实或者可能性较大。当用于否定句或疑问句时,后面则接should或can/could,对事实或可能性提出质疑或根本不相信。
我会尽快来。误I'll come as soon as possibly.
正I'll come as soon as possible.
析as...as possible是as...as it is possible缩略形式,只能用形容词possible,不可用副词possibly。
你今晚能来吃饭吗?误Are you possible to come to dinner this evening?
正Is it possible for you to come to dinner this evening?
析当表示“某人有可能做某事”时,须用It is/was possible for sb to- v 结构,不能用sb is/was possible to- v 结构,即possible不能以人作主语。
