答案解析

B。本题出题点在文章末段的因果关系处(For these reasons)。根据题干信息词dried foods将答案锁定在文章末段。末段提到，脱水食物与同类罐装食品和冷冻食品相比，占用空间较小，重量较轻，而且不需要特殊的储存条件，因此适合没有多少存储空间的登山者、探险者和作战士兵，由此推断，脱水食物经常为士兵和登山者所用，故选B。

1 根据以下资料，回答题：
        As a child I was slave to my impulses; now I am slave to my habits, as are all grown men．I have surrendered my free will to the years of accumulated habits and the past deeds of my life have already marked out a path which threatens to imprison my future．My actions are ruled by appetite, passion, prejudice, greed, love, fear, environment, habit, and the worst of these tyrants is habit．Therefore, if I must be a slave to habit let me be a slave to good habits．My bad habits must be destroyed and new furrows prepared for good seed．I will form good habits and become their slave．
        And how will I accomplish this difficult feat? Through these scrolls, it will be done, for each scroll contains a principle which will drive a bad habit from my life and replace it with one which will bring me closer to success．For it is another of nature's laws that only a habit can subdue another habit．So, in order for these written words to perform their chosen task, I must discipline myself with the first of my new habits which is as follows: I will read each scroll for thirty days in this prescribed manner, before I proceed to the next scroll．
First, I will read the words in silence when I arise．Then, I will read the words in silence after I have partaken of my midday meal．Last, I will read the words again just before I retire at day's end, and most important, on this occasion I will read the words aloud．
        On the next day I will repeat this procedure~ and I will continue in like manner for thirty days．Then, I will turn to the next scroll and repeat this procedure for another thirty days．I will continue in this manner until I have lived with each scroll for thirty days and my reading has become habit．
        And what will be accomplished with this habit? Herein lies the hidden secret of all man's accomplishments．As 1 repeat the words daily they will soon become a part of my active mind, but more important, they will also seep into nay other mind, that mysterious source which never sleeps, which creates my dreams, and often makes me act in ways I do not comprehend．
        As the words of these scrolls are consumed by my mysterious mind I will begin to awake, each morning, with a vitality I have never known before． My vigor will increase, my enthusiasm will rise, my desire to meet the world will overcome every fear I once knew at sunrise, and I will be happier than I ever believed it possible to be in this world of strife and sorrow．Eventually I will fmd myself reacting to all situations which confront me as I was commanded in the scrolls to react, and soon these actions and reactions will become easy to perform, for any act with practice becomes easy．Thus a new and good habit is born, for when an act becomes easy through constant repetition it becomes a pleasure to perform and if it is a pleasure to perform it is man's nature to perform it often．When I perform it often it becomes a habit and I become its'slave and since it is a good habit this is my will．Today I begin a new life．
