本文是一篇说明文，介绍了一些帮助你在夜里醒来后再次入睡的有效方法。
【16题详解】
空前说许多人常常发现自己半夜醒来，异常清醒和兴奋，此处承接上文，讲的是他们醒来后就再难以入睡的情况，故G项（他们在床上辗转反侧，睡不着觉）符合语境。
【17题详解】
空前说睡前不要喝东西充盈膀胱，空后又说它可能会让你睡得更快，但也可能扰乱你的睡眠，因此此处是说睡前尤其不要喝酒，故D项（最重要的是，晚上不要喝酒）符合语境。
【18题详解】
空前说当你无法入睡时，打印机和电缆盒上的LED灯可能是原因，从窗帘的缝隙射入的光线也同样如此，此处总结上文，讲的是打印机和电缆盒上的LED灯以及从窗帘的缝隙射入的光线可能会让你睡不着觉，故C项（它们可能会让你保持清醒）符合语境。
【19题详解】
空前说尝试放松的方法，比如深呼吸、冥想和正念练习，此处承接这一话题，介绍的是另一种让大脑平静下来的方法，故E项（你可以在脑子里做简单的数学题）符合语境。
【20题详解】
空后说如果你早上6点半起床，凌晨3点的时候你醒了，不要想我只能睡三个小时了，相反，要这样想——我还能睡三个小时呢，这个例子说明要以积极的方式思考，故A项（以积极的方式思考）符合语境。
【点睛】在七选五的解题过程中，选项中出现的代词与上文中出现的某一（些）名词的指代关系往往是重要线索，例如本篇第3题，根据空前的“When you cannot sleep, LED lights on printers and cable boxes may be the reason. The same is true for light streaming in through cracks in curtains.”可知，当你无法入睡时，打印机和电缆盒上的LED灯可能是原因，从窗帘的缝隙射入的光线也同样如此，空处总结上文，讲的是打印机和电缆盒上的LED灯以及从窗帘的缝隙射入的光线可能会让你睡不着觉，C项中的They指代的就是前面提到的打印机和电缆盒上的LED灯以及从窗帘的缝隙射入的光线，故C项（它们可能会让你保持清醒）符合语境。
