Paragraph Eight Summer is the ideal time for one of the great outdoor activities, hiking. It is much more than just a great workout.

When hiking in the deserts, you suddenly realize that life is precious and you will think deeply about your life. 43. Hiking is a b_____ activity.
【正确答案】：beneficial
【题目解析】：本段主要讲的是远足的好处。比如可以呼吸新鲜、干净的空气，忘却纷繁的城市生活。或者在沙漠中远足能够顿悟到生命的可贵并深度思考生活的意义。所以我们总结为远足是一项有好处的活动。因此我们填beneficial。
