1. After getting too little sleep Monday through Friday, many teens try to catch up on weekends, sometimes straggling out of bed after noon. While they may feel like they are doing their bodies a favor, they actually aren’t.

Catch up: 补觉

Straggle: move along slowly缓慢移动

Do someone a favor: 帮某人忙

在周一到周五睡眠不足之后，许多青少年试图在周末补觉，有时中午过后才从床上爬起来。虽然他们可能觉得这样对自己的身体有好处，但实际上不是。

2. A whopping 80% of teens sleep fewer than the recommended nine hours per night, especially during the school week. Staying up late in the evening to finish schoolwork, take part in extracurricular activities, and spend time with friends and family means they often struggle to wake up on time for school. A few days of this can build up a significant sleep deficit.

Whopping: 高达

Stay up late: 熬夜

Build up: 积累

Sleep deficit: 睡眠不足

高达80%的青少年每晚睡眠时间少于建议的9小时，尤其是在上学的周间。熬夜完成作业，参加课外活动，与朋友和家人共度时光，这意味着他们经常很难按时起床上学。这种情况持续几天就会导致严重的睡眠不足。
