不定式动词(Infinitive)的形式是:“to + 原动词”, 如:to come, to go, to play, to read, to listen, to sing等等。
在一般情况下,“to + 原动词”必须靠拢,但在某些情况里,“to”和原动词可以被适当的副词(Adverb)分开,在某些动词句型里,“to”则必须省略。
在什么情况下,不定式动词的两部份可以分开呢?分开的目的何在?在大多数场合里,不定式动词两部分不分开,只有在特殊环境里才准许让副词加入,以便更准确地,更自然地反映某些实际情况。看看下面三个句子:
(1) Bob failed completely to fulfil his duties.
(2) Bob failed to fulfil his duties completely.
(3) Bob failed to completely fulfil his duties.
在(1)里,状态副词“Completely”既可修饰谓语动词“failed”,也可修饰不定式动词“to fulfil”。在 (2) 里,“completely”和被修饰的不定式动词离开太远,力道不足,效果欠佳。在 (3) 里,“completely”夹在不定式动词两部份之间,把它修饰得既自然又贴切;这个位置,在三个句子中,可说是最恰当的了。
同样的,(4)比(5)紧凑;(6)比(7)扎实:
(4) It was wrong for Mr Lim to suddenly quit the job.
(5) It was wrong for Mr Lim suddenly to quit the job.
(6) Is it possible for a chaotic country to further develop its economy?
(7) Is it possible for a chaotic country to develop its economy further?
由于不定式动词的两部分在适当时分开有其优点,这种用法,在现代英语里越来越普遍。例如:
