题目内容
The fire spread through the hotel very quickly but everyone ________ get out.
- A.had to
- B.would
- C.could
- D.was able to
通过排除应保留表示“能;能够”含义的选项,而could和was able to之间的区别在于在表示过去持续的能力,可能性的时候用could,但是表示某一时间段(只有一次)的能力,时用was/were able to.was/were able to do相当于managed to do或succeeded in doing sth.,强调过去动作的结果,表示成功地完成某一具体动作:“大家都设法逃了出去”.
