Or maybe you miss every free throw during your basketball game—and to top if off, you are not friendly to your teammate on the way to the locker room. These may seem like unrelated events, but here’s the surprising truth: Each may be a direct consequence of your lack of sleep time. In one study, just an hour less of sleep each night made sixgraders perform like fourthgraders on mental tests. Other research shows that sleep loss makes you run slower and miss more shots in sports, while doubling your possibility of injury. Some experts even argue that teens would be less likely to take risks or suffer from anxiety if they could just get enough sleep. “When you lack sleep and you run into a stressful situation, whether it’s with your friends or something else, you’re going to get angry and upset, ” explains Dr. Kathleen Berchelmann, a doctor in St. Louis, Missouri. “I see a lot of depression and anxiety in teens who aren’t getting enough sleep. ”It’s surprising to think that by spending more time in bed, you could lift your grade point average, get along with your loved ones, perform better on the field, and feel happier. But scientists say it’s true—many teens are walking around like zombies (僵尸) without even realizing it. 【文章大意】本文是一篇說明文, 講述青少年缺乏睡眠的不良后果。28. The first paragraph serves as a(n) _______.
