【解析】

本文是一篇说明文。水是细胞健康的基本需求。保持充足水分会给你的健康带来好处。文章叙述了水会给人的健康带来的好处。

1.上文提示“水是细胞健康的基本需求。”再根据下文提示“所以，给自己倒一大玻璃杯水，坐下来，可以看到保持充足水分会给你的健康带来好处。”承接上下文，C项It can have a magic power to your mind and body（它可以给你的思想和身体带来神奇的力量）切题。该项中的it指上文的water；该项通过so和下文构成因果关系。故选C。

2.下文提示“当你脱水的时候，细胞的功能就不太好了而且流动也不会很顺利，影响你的身体和精神表现，让你感觉迟钝”。承接下文，E项Water helps keep up a steady flow of nutrients into your cells（水有助于保持源源不断的营养物质进入你的细胞）切题。故选E。

3.上文提示“当人们每天增加1到3个8盎司的水（在他们已经喝了4杯的时候），他们吃得更少。”承接上文，G项The research is less clear on whether this pattern holds true for adults（研究还不太清楚这种模式是否适用于成人）切题。该项中的this pattern指上文内容。故选G。

4.上文提示“研究一直发现，孩子喝完水后，记忆力和注意力都得到了改善。”承接上文，D项Their food intake dropped by as much as 205 calories a day（他们的食物摄入量每天减少了205卡路里）切题。故选D。

5.此空是小标题。根据上文中的小标题，可知应在A/B中选择。根据下文提示“当来自康涅狄格大学的一项小型研究中，通过汗液女性的体重仅减少了1.36%（并且没有喝足够的水来替代它），她们的情绪变糟了，她们更容易感到头痛和疲惫。”由此可知，A项You’ll be in higher spirits（你会情绪高涨）切题。故选A。
