【分析】
这是一篇健康主题的阅读理解题，解题时首先通读全文，梳理文章各部分的核心内容：文章分别介绍了健康饮食习惯、更换牙刷的注意事项、定期锻炼的要求、合理规划三餐的相关内容。之后逐题对应考点解题：第5题主旨大意题需要整合所有段落的共同核心，排除片面的选项；第6题是选段落小标题，直接定位空后段落的核心描述匹配选项；第7题是细节计算题，从原文找到锻炼的频率和单次时长，计算每周最低总时长即可；第8题是细节理解题，汇总文中提到的保持健康的要素匹配选项。
【解析】
5. 主旨大意题：文章涵盖健康饮食、定期更换牙刷、规律运动、合理规划日常三餐多个维度的健康相关内容，A选项仅提到健康食物、C选项仅提到健康运动，都过于片面；D选项健康计划只覆盖部分内容，不符合全文核心，全文整体围绕健康的生活方式展开，选B。
6. 段落标题选择题：空后段落核心内容是旧牙刷容易带来疾病，需要经常更换牙刷，对应C选项“更换牙刷”；A扔掉牙刷、B买牙刷、D清洗牙刷都不符合段落核心表述，选C。
7. 细节理解计算题：原文明确说明“你应该每周至少锻炼3次，每次锻炼20分钟或更久”，计算可得每周最低锻炼总时长为3×20=60分钟，也就是一小时，选A。
8. 细节理解题：文中明确提到健康饮食计划、合理锻炼都能帮助我们保持健康，没有提及睡眠相关内容，因此符合的是合适的饮食和锻炼，选C。

【点评】
本题属于生活化主题的基础阅读题，整体难度不高，多数错误集中在第7题，不少同学会直接把单次锻炼的20分钟当成每周总时长误选B，另外第5题容易误选D选项，要注意区分局部内容和全文主旨，不能以偏概全。
