Will you be able to come? I’m able to do the work all by myself. 例：They ______escape from the fire. A. can B. are able to 答案：B ii） can be able to ?表示“能力”时,be able to 不用于第二人称 ??eg., You are able to do the work, I think. ?can与感官动词feel, hear, see, smell, taste连用时, can显得可有可无,因而失去了情态动词的意义,这种情况下can不能用be able to 代替 eg. We can see beautiful flowers and green trees here and there. Anyone can see it is of no use. ?can与某些表示意念的动词如：understand, remember, forget, hope, imagine, believe, suppose等连用时，同样没有情态动词的意义，因而也不可用be able to取代。 eg. I can’t believe there are so many tall buildings now in my home town. iii） can be able to ?can和be able to的过去时分别是could和was/were able to ?was/were able to 意含“经过努力” “凭借才能” 获得的“能力”常与“manage to”相通 eg. He started early, and he was able to arrive the earliest. They worked hard, so they were able to do more for the company They were short of modern machines, but
