B(2024·南通启东期末)
Do you play with your phone before bedtime? You may want to read a book instead. According to a US study, looking at screens at night can cause(导致) us to sleep poorly.
In the evening, our bodies make melatonin(褪黑素). Melatonin helps us feel sleepy and relaxed. It is an important part of our sleep cycle(周期). Our electronic screens stop that cycle from working well.
Why? Phones, computers and TVs make blue light. Blue light stops our bodies from making melatonin. Even just a little bit of blue light can have an effect. Eight minutes of blue light can keep your brain “awake” for another hour, according to the study. Even if you fall asleep, you may have lots of dreams. Your brain won't have a good rest.
It's even worse if you play an exciting game before bedtime. Games make our hearts beat faster, so we have a harder time falling asleep. Then, when we fall asleep, we don't get enough “deep sleep”, which results in poor health.
Use these tips to get a good night's sleep:
Have a relaxing routine every night. Take a warm shower or read a book.
Sleep in a dark, quiet room that is not too warm or too cold.
Count sheep. It's the oldest trick, and it can actually work!
Don't eat a big meal or have caffeine(咖啡因). Instead, drink milk.
Don't run around or exercise three hours before bedtime.

答案： 1. D 提示:细节理解题。根据第二段第二句“Melatonin helps us feel sleepy and relaxed.”可知,褪黑素帮助我们感到困倦和放松,有助于我们的睡眠。
2. C 提示:细节理解题。根据“Take a warm shower or read a book.”可知,选项 A 错误;根据“Don't run around or exercise three hours before bedtime.”可知,选项 B 错误;根据“Don't eat a big meal or have caffeine.”可知,选项 D 错误。选项 C 是原文中“Sleep in a dark, quiet room”的同义转述。
3. C 提示:细节理解题。根据第四段第二句“Games make our hearts beat faster, so we have a harder time falling asleep.”可知,游戏使我们的心跳加快,所以我们很难入睡,因此选项 A、B、D 错误;根据褪黑素的作用和文中提供的建议可推知,睡觉之前感到困倦和放松很重要,C 项正确。
4. D 提示:主旨大意题。文章第一段开门见山,点明文章讨论的主题“晚上看电子屏幕对睡眠有影响”,随后就其原因进行了分析,由此可推知,文章主要讨论了玩手机如何导致睡眠不佳。
