【解题导语】 本文是一篇说明文。文章主要指出了相比于食物，人们存活更需要水。人体内可以存储一些脂肪和能量备用，而呼吸和其他身体活动却随时随地在消耗人体内的水分。
1．C 解析：此空设于段尾，与上文存在逻辑上的指代关系。本句中的That指代的是前一句中提到的The fatter you are, the more fat your body can store.。
2．D 解析：此空设于段中，是对前一句的进一步解释。此句和后一句都是对前一句的进一步解释。前一句指出，气候在人们存活的过程中扮演着很重要的角色，此句和后一句
分别提出冷天气和炎热的气候是如何具体影响的。
3．G 解析：此空设于段首，是本段的主题句。此句提出，吃得太少会使身体作出一些特殊的反应，接着后文再具体描述这些反应。
4．A 解析：此空设于段中，与后文存在转折关系。本段主要是讲缺水可能会带来的后果。后一句句意为“否则，我们可能会中暑。”由此可推测，此句是提出水可以使我们在炎热的天气凉快下来。
5．F 解析：此空设于段中，是对第一句的进一步解释。第一句指出，严重脱水可以导致很多疾病，接着提出了刚开始的后果。所以可推测，此句是表明几周后，你可能会处于休克状态。
