解析

【分析】
这是一篇介绍优质睡眠方法的说明文类任务型阅读,解题时先通读全文理清行文逻辑,再逐空结合上下文线索匹配选项:
1. 先定位第1空所在段落,后文明确提到不要熬夜、要保证6-8小时夜间睡眠,核心是倡导规律作息按时睡觉,匹配对应主题的选项;
2. 第2空前后都围绕“开灯睡觉”展开,前句点明不要开着灯睡,后句说明有光时睡眠质量差,中间需要衔接和光线来源相关的内容;
3. 第3空前提出很难保持右侧睡姿的问题,后文提到在左侧放置物品防止往左侧翻滚,需要匹配能给出对应解决方案的选项;
4. 第4空所在段落说明不要在床上做阅读、看电影等无关活动,要让床和休息建立关联,匹配对应主旨的选项;最后排除多余选项,结合文章内容按词数要求回答开放性问题即可。
【解析】
1. 第1空:本段核心强调不要熬夜,要保证充足的夜间睡眠时间,E选项“在合理的时间上床睡觉”完全契合段落主题,因此选E。
2. 第2空:前句提出不要开着灯睡觉,后句说明在光线中睡眠会休息不足、睡醒后幸福感更低,D选项“光线通常来自电视、电脑和小夜灯”承接上下文,解释了此处提到的光线的常见来源,逻辑衔接顺畅,因此选D。
3. 第3空:前句提出很难长时间保持右侧睡姿的问题,后句说明在左侧放置物品可以防止自己滚到左侧,B选项“考虑买一个长抱枕”给出了该问题的可行解决方法,符合行文逻辑,因此选B。
4. 第4空:本段指出在床上进行阅读、看电影等活动会影响睡眠,会让床和刺激而非休息建立关联,C选项“记住床是用来睡觉的”精准概括本段核心主旨,因此选C。
5. 第5题为开放性问题,结合文中提到的睡眠方法说明对应理由,控制词数不超过20即可。
