How to Sleep Better

If you’re having trouble getting good sleep through the night (turning, waking up more than once, for example), this text will tell you what you can do to ensure a peaceful night’s sleep.

1. Get up on time. Changing your sleeping time by more than an hour can severely disturb (干扰) your sleep quality. 1. For example, if you normally wake up at 6 am on weekdays to get to work, you might go to bed around 10 pm, because that’s when you start to feel sleepy, and it’s also a good time to ensure 8 hours of sleep. If, on the weekend, you sleep until 9 am, you probably won’t be able to fall asleep that night until 1 am.

2. 2. Wait at least three hours after dinner before going to sleep. Digestion(消化) slows down while asleep, and a full stomach may interrupt(打搅) sleep. Similarly, you should avoid going to bed on an empty stomach, as a completely empty stomach may equally disturb your sleeping patterns(模式).

3. 3. Exposure(暴露) to light during the time when you’re supposed to be sleeping can disrupt(扰乱) your body’s internal clock. Turn your light off, or use a very dim night light. 4.They include windows, LED clocks, computer lights and cable boxes.

4. Change your sleeping position. You may think that it’s impossible to control what position you sleep in since you don’t fully understand what you are doing, but it is possible and it can make a big difference. 5.

A. Try to avoid all sources of light.

B. Keep the room as dark as possible.

C. Make note of unusual circumstances (状况).

D. Be mindful of what you eat or drink before bed.

E. Sleep is considered to be adequate only when there is no daytime sleepiness.

F. In other words, sudden change of sleeping time will affect your “biological(生物的) clock”.

G. If you wake up in the middle of the night, make an effort to have a comfortable position.

【解析】

本文属于说明文阅读。作者通过这篇文章给出了一些保证良好的睡眠的方法建议。

1.考查对上下文的理解及推理判断能力。本段的中心词为“准时起床”。根据上文提到Get up on time. Changing your sleeping time by more than an hour can severely disturb your sleep quality.（准时起床。改变睡眠时间超过一小时会严重影响睡眠质量。）可知，F项“换句话说，睡眠时间的突然改变会影响你的“生物钟””是上一句的解释，故选F项。

2.考查对上下文的理解及推理判断能力。根据下文中提到Wait at least three hours after dinner before going to sleep．（吃完饭至少三个小时后再睡觉），D项“注意睡前吃或喝的东西。”与下文的内容一致，故选D项。

3.考查对上下文的理解及推理判断能力。根据下方提到Exposure to light during the time when you’re supposed to be sleeping can disrupt your body’s internal clock可知，光照会打乱你的生物钟，故B项“当你睡觉时尽可能保持黑暗”概括本段内容。故选B。

4.考查对上下文的理解及推理判断能力。本段的中心为“睡眠与光线”。根据上文提到Turn your light off, or use a very dim night light.（关上所有的灯或用昏暗的夜灯），再根据下文They include windows, LED clocks, computer lights and cable boxes.（它们包括窗户，LED闹钟，电脑灯光，有线电视盒），故空格处表示“避免所有的光线”，故选A。

5.考查对上下文的理解及推理判断能力。本段的中心句为“改变你的睡姿”，接着叙述睡姿会对你产生很大的影响。分析选项可知G项“如果你在午夜醒来，努力保持一个舒适的姿势”与本段中心词sleeping position复现，而且意义一致。故选G。
