考试不仅是脑力的考试，更是一场体力的考试，几场考试下来要持续好几个小时，我们身体的能量会被大量消耗，而肚子饿了的一个特征就是胃部会发出响声。但是给我一条士力架，就能给我提供足够的能量，让我的胃部“遵守考试规则”集中精力考完全场！The examination is not only the mental test,it is a physical examination.A few exams will continue for several hours, we will consume a lot of energy.When I am hungry,a feature will appear which is that our stomach will make sounds. At this time if I have a Snickers,it can give me enough energy to make my stomach "obey the rules of examination" to concentrate on the exams!
