Many students like to do other things right after studying. Some check their phones or use
computers. Others play video games or watch TV. But studies show that having a rest after studying
can help you remember what you've learned. The idea is this: by stopping your activity after the
study, your brain(大脑) gets a chance to rest. It's hard for your brain to rest when you're playing
computer games. You might think this is strange, but lots of studies show the good things about
"wakeful rest"— ▲ .
In 2019, a study found that both young people and older people could remember what they learned
better after doing wakeful rest. If you want to try wakeful rest, it's easy. Just sit quietly for 5 to 10
minutes. Don't look at your phone, read books, or play games. That's all!
Sleep is also very important for learning. The Division of Sleep Medicine at Harvard Medical
School says sleep helps us learn in two ways. Their website says, "If you don't get enough sleep, you
can't focus on something well, so you can't learn well." And sleep helps us remember things, and
remembering is key when learning new things.
The National Sleep Foundation(NSF) says adults aged 20 to 64 should sleep 6 to 7 hours a day.
Teenagers may need a bit more sleep, and people over 65 may need a bit less. So, try some wakeful
rest after studying. Then, get a good night's sleep. These are simple and free ways to help you
remember what you learn.

【语篇导读】本文主要说明了学习后进行清醒休息和保证充足睡眠对记忆的重要性,说明了什么是清醒休息以及如何进行清醒休息,并提到了睡眠对学习的帮助和不同年龄段人群的睡眠需求。
5. D 提示:细节理解题。根据第二段第二至四句"If you want to try wakeful rest, it's easy. Just sit quietly for 5 to 10 minutes. Don't look at your phone, read books, or play games."可知,尝试清醒休息只需静静地坐5到10分钟,期间不要看手机、读书或玩游戏。"静静地躺8分钟,不使用手机或阅读"符合学习后进行清醒休息以帮助记忆的建议,故D项正确。
6. D 提示:推理判断题。空处位于破折号后,说明是对"wakeful rest"的概念进行解释说明。通读第一、二段可知,清醒休息指的是学习后安静休息,不使用手机或进行其他活动。D项"那就是在学习后仍然清醒时进行休息"与之吻合。
7. C 提示:细节理解题。根据最后一段第一、二句"The National Sleep Foundation says adults aged 20 to 64 should sleep 6 to 7 hours a day. Teenagers may need a bit more sleep"可知,20到64岁的成年人每天应睡6至7小时,青少年的睡眠时间应略多,四个选项中只有"约8小时"符合题意。
8. C 提示:最佳标题题。通读全文可知,文章主要讲述了学习后进行清醒休息和保证充足睡眠对记忆的重要性,说明了什么是清醒休息以及如何进行清醒休息,并提到了睡眠对学习的帮助和不同年龄段人群的睡眠需求。由此可见,文章以"休息的力量:两种免费提升学习效果的方法"作为标题最合适。
