be able to能否有被动语态?
be able to可和有生命的主语甚至与无生命的主语连用:I have not been able to write for several days—G. Vidal, 1955; a yarn about not being able to keep a job—K. Amis, 1978;By his proceeding to the beach ... the next phase of the attack was able to proceed—New Yorker, 1986赋予无生命主语以能力,并不总是可取的,如果所接的动词不定式是被动的,那句子就很勉强:No evidence that an air rifle was able to be fired— Times (heading of Law Report), 1988.总体上,最好用情态动词can/could 加被动式,或者把句子写成主动的形式【题】That mistake is ____ corrected.
