这是一篇介绍保持健康方法的说明文，我们可以根据上下文逻辑逐一匹配选项：
1. 空前句点明保持健康很重要，空后开始逐条介绍保持健康的具体做法，B选项“这里有一些简单的方法”可以承上启下，引出下文的几条建议，符合语境。
2. 空前介绍要多吃有益健康的果蔬，空后提到“它们含有大量脂肪和糖，对健康没有好处”，G选项“不要吃太多像汉堡、薯片这类的垃圾食品”符合逻辑，空后的They正好指代句中的垃圾食品，衔接通顺。
3. 空前点明第二条建议是找时间锻炼，空后举例说明日常散步、骑车这类简单运动就可以，C选项“你不必做难度很高的运动”符合语境，引出后文的简单运动举例。
4. 空前提到可以和朋友打篮球、游泳这类运动，F选项“这会让你感觉很舒服，还能让你的身体保持强壮”，这里的It指代前文提到的各类运动，补充说明运动的好处，衔接自然。
5. 空后内容都围绕充足睡眠的重要性展开，前文已经用First、Second引出前两条建议，A选项“最后，保证充足的睡眠”对应第三条建议的开头，符合行文逻辑。
剩余的D、E两个选项和上下文语境不匹配，为多余选项。
