1. 01Are Students Getting Enough Sleep?

   Good morning, everyone. Many of us come to class tired, and we think it's normal. Today, I'll compare what sleep experts recommend with what my classmates actually do.

   大家早上好。我们很多人来上课时都很累，而且觉得这很正常。今天，我想把睡眠专家的建议和我同学们的实际情况做个比较。

2. 02What Experts Recommend

   According to the American Academy of Sleep Medicine, teenagers aged thirteen to eighteen should sleep eight to ten hours a night. Younger children need even more: nine to twelve hours.

   根据美国睡眠医学会的建议，十三到十八岁的青少年每晚应该睡八到十个小时。年龄更小的孩子需要的更多：九到十二个小时。

3. 03My Class Survey

   To see how we compare, I did a small survey. I asked thirty classmates how many hours they usually sleep on school nights.

   为了看看我们的情况如何，我做了一个小调查。我问了三十位同学，他们在上学日的晚上通常睡几个小时。

4. 04The Results

   The results were clear. Only six out of thirty students sleep eight hours or more. Most of us sleep between six and seven hours, and some sleep less than six.

   结果很明显。三十位同学中只有六位睡够八个小时或更多。我们大多数人睡六到七个小时，有些人甚至不到六个小时。

5. 05Why We Sleep So Little

   When I asked why, three reasons came up again and again: using phones in bed, finishing homework late, and having to get up early for school.

   当我问原因时，有三个理由反复出现：躺在床上玩手机、作业写到很晚，以及第二天要早起上学。

6. 06What Some Doctors Suggest

   Interestingly, the American Academy of Pediatrics has recommended that middle and high schools start at eight thirty or later, so that students can get enough sleep.

   有意思的是，美国儿科学会曾建议，初中和高中的上课时间应定在八点半或更晚，好让学生能睡够觉。

7. 07What We Can Do

   Based on these results, I have three suggestions. Let's keep phones out of the bedroom, plan homework earlier in the evening, and talk to our school about start times.

   根据这些结果，我有三个建议。我们把手机放在卧室外面，晚上早点安排写作业，并且和学校谈谈上课时间的问题。

8. 08Conclusion

   To sum up, most of us sleep less than experts recommend. Sleep is not a waste of time; it's part of learning. Tonight, try going to bed thirty minutes earlier. Thank you.

   总之，我们大多数人的睡眠时间都少于专家的建议。睡觉不是浪费时间，而是学习的一部分。今晚，试着早睡三十分钟吧。谢谢大家。
