你知道was able to與could的區(qū)別嗎 下面這一題你會做嗎? The fire spread through the hotel quickly but everyone __________ get out. A. had to B. would C. could D. was able to 此題應(yīng)選D。容易誤選C(could)。這里主要涉及could與was able to的用法和區(qū)別: 1. 表示過去一般性能力時 (即某人想干什么就能干什么能力),兩者都可用: He could [was able to] run very fast when he was a boy. 他小時候跑得很快。 2. 表示過去特定的能力 (即某人在某一具體場合做某事的能力,往往暗示經(jīng)過努力才具備的能力),通常用was(were)able to,也可用managed to do sth或succeeded in doing sth,但是不能用 could: 他學(xué)習(xí)很努力,所以考試及了格。 正:He worked very hard and was able to [managed to] pass his examination. 誤:He worked very hard and could pass his examination. 正因為此原因,所以上面一題的答案用 ...was able to get out,而不用...could get out,因為此題談及的是一種特定場合的具體能力。(www.hz123456.com) 但值得注意的是,以上用法只適合于肯定句,若在否定句中,則可用couldn’t代替 wasn’t [weren’t] able to: He worked hard but wasn’t able to[couldn’t] pass the exam. 他學(xué)習(xí)很努力,但考試卻未能及格。
