本文是一篇说明文。文章告诉我们挤出时间锻炼身体的好处，而晨练的好处更大，对身体和工作都有所裨益。
1．G 解析：本空前文说在繁忙的生活中，我们很难找到时间锻炼，后文说晨练的好处，故中间的衔接句可表达“假设有时间锻炼”之类的含义，因此G项符合语境。
2．E 解析：本段的主旨是“晨练能提高你的效率”，E项“锻炼之后的4到10小时内，你都能让自己头脑清醒”追加了锻炼的好处，符合此处的语境。
3．F 解析：这一段说的是晨练有助于人体的新陈代谢，能让你一整天都感受到晨练消耗卡路里带来的好处，F项“晨练之后你还会在一天时间里继续消耗卡路里”符合语境。F项中的关键词throughout the day与文中的the whole day呼应。故选F。
4．B 解析：本题考查段落主题句。本段提到slept better，more difficult to relax，a peaceful sleep，因此这一段说的是晨练比晚上锻炼更能改善睡眠，因此选B。
5．A 解析：由本段的关键词stick to healthy food choices, eating junk food, positive choices等可知，这一段说的是晨练对饮食的影响，因此选A。
