        1. — Dad, why should I stop ______ computer games?
          — For your health, my boy, I’m afraid you ______.
          A.to play; mustB.playing; have to
          C.to play; canD.playing; may
          B

          試題分析:句意:---爸爸,為什么我必須停止玩電腦游戲?—孩子,為了你的健康,恐怕你不得不停下來。這里是短語stop to do sth停下來去做某事;stop doing sth停止正在做的事情;根據(jù)答語For your health, my boy可知第一空應(yīng)該是停止玩游戲,所以應(yīng)該用stop doing sth;故排除AC;have to不得不,表示客觀的原因;may也許。根據(jù)句意故選B。
