28、t enough sleep.GAfter all，your bed is likely one of the most comfortable spaces in your home.【语篇解读】本文介绍了五种方式来帮助青少年获得更好的睡眠。1F由“Dont stay up late to study”中的“Teens are often found staying up late to study. Studies show sleep helps you understand and remember information. If you think you badly need to

29、 study more，get up early and study in the morning instead.”可知，经常发现青少年熬夜学习。研究表明睡眠有助于你理解和记住信息。如果你认为自己迫切需要多学习，那就早起，在早上学习。所以空处在文中要起到承上启下的作用。故F选项“这就是为什么青少年经常在睡眠不足时成绩很差的原因”符合句意。故F选项切题。2B由“Sleeping with your smartphone nearby results in 21 minutes less sleep each night. If your phone is easy to reach，youll

30、 probably end up using it when you should be dreaming.”可知，每天晚上在手机旁睡觉的人每天会少睡21分钟。如果你的手机很容易拿到，那么你很可能在做梦的时候就会用上它。所以本段主要在说明睡觉时手机在旁边所带来的害处，意在告诉我们睡觉时不要把手机放在身旁。也就是本段的标题所要表达的内容。故B选项“睡觉时不要把手机放在身旁”符合句意。故B选项切题。3E由本段标题“Turn your phone on airplane mode”可知，将你的手机切换为飞行模式。所以空处要说明手机飞行模式所能够起到的作用。故E选项“直到你早上关掉飞行模式，你的短信才

31、会出现”符合题意。故E选项切题。4A由“Create a bedtime routine”中的“Having a bedtime routine will cause your body to prepare for sleep around that time each night. Set a time you think is proper and stick to it.”可知，每天晚上有规律的睡觉时间会让你的身体为睡觉做好准备。设定一个你认为合适的时间并坚持下去。故A选项“睡觉的时间不只是为婴儿设定的”符合句意。故A选项切题。5D由“Use your desk for working and your bed for sleeping”中的“Getting into bed to do homework，read，or check your phone may make you feel good”可知，躺在床上做作业、阅读或查看手机可能会让你感觉良好。所以空处要与前一句话表示转折关系，才能够说明本段的主题。通过对比选项，只有D选项中有转折连词but。故D选项“但是上床睡觉应该是睡觉的信号，而不是要做其他活动的信号”符合句意。故D选项切题。
