1.The fire spread through the hotel very quickly but everyone _____ get out .

 A. had to    B. would    C. could      D. was able to    NMET1997 

   解析:could与was (were )able to 都可以表示过去的能力。Could指过去的习惯能力,表示主语处于“能够”做某事的状态,was (were) able to不仅表示“能够”做某事,而且表达实际上已经成功地做了某事,用于过去某一实际场合。

答案:D。

   人大火中逃出,是发生在某宾馆一次火灾中的具体行动,只能用was able to, 此题不能用表示天生的或学到的具备做某事能力的could去取代。

(2)  推测

1.情态动词can, could, may; might基本用法。

(1) 许可can/could

(a)   请求can/could I…?用could婉转。
