Question

【题目】The small boat was almost sunk by the dinosaurs which suddenly ________ to the surface, fighting each other, but fortunately the three men ________ get away.

A. rose; could B. rose; were able to

C. arose; could have been able to D. raised; could have

Answer 1

【答案】B

【解析】

试题分析：考查动词辨析和情态动词。句意：那只小船几乎被突然浮出水面的恐龙弄沉，但是好在船上的三个人及时逃脱了。rise上升，增加，不及物；arise出现，引起；raise提高，养育，是及物动词；rise to the surface上升到水面；could表示理论上的可能性，即这种可能性不一定会成为现实；根据“fortunately”可知，三人成功逃脱了，was/were able to表示已经发生了的可能性，could have done表示本可以，言外之意是三人没有逃脱，与句意不符，故选B。
