Answer 1

答案：1．B;2．D;3．A;4．C;5．A;
解析：

(1)	细节理解题．根据第二段“The ankle was the most common body part to be injured (40 percent)．”可知踝关节是最容易受伤的部位，因此答案是B。
(2)	推理判断题。第二段首句说从1991到2008年间，美国大约有4万人因为爬山时受伤而接受治疗，本段最后一句又提到“women took up a quarter of the injuries”，可知答案是D。
(3)	细节理解题。根据第三段“The severity of fall-related injuries had a lot to do with the height of the fall。”可知摔下来的高度是决定受伤程度的主要因素，因此A项正确。
(4)	词义猜测题。根据语境，爬山者住院率高于参加其他体育和娱乐活动的人，这“证明”了爬山者要更加注意预防受伤。C项意思最合适。
(5)	作者意图题。文章是一篇说明文，主要是告诉读者与爬山运动相关的伤害增加了，因此A项是最佳选项。
