【回答】
篇章导读：本文是一篇说明文。很多人觉得早上起床很困难并将其归咎于闹钟。其实，要想早上轻松起床，关键是要调整自己身体的生物钟，也就是制定一个良好的睡眠计划。具体如何做呢？一起来看看作者给出的锦囊妙计吧！
1．C 空前提到要调整身体的生物钟，那么如何调整呢？空后的“Here's how to make one.”中one又指什么呢？浏览各选项，只有C项(一个更好的睡眠计划会有所帮助)符合上下文语境。
2．B 显然，该空应填本段的主题句。由本段中的“为了作出改变，你需要决定为什么它很重要”及“一旦你清楚了自己的理由……”等描述可知，你要想清楚为什么要早起，故选B项“找到合适的动机”。
3．G 由空后的“bought a coffee maker”可锁定G项(重新考虑你用在咖啡馆排队买咖啡的15分钟)。
4．F 由本段首句可知本段主题是“在周末要坚持(执行)你的睡觉和起床时间表”，与此主题符合的只有F项(不管哪天都要坚持你设定的就寝和起床时间)。
5．E 本段讲的是每周要记录并评价你的计划，如果有效，就继续坚持，如果无效，就看看其他你可以尝试的方法。由空后的If not也可直接锁定E项(如果你采取的措施起作用了，那就坚持下去)。
