任务型阅读 When the morning sun looks in through your bedroom window, do you jump out of bed? Or do you roll over and groan? Enough sleep can make the difference between a great day and a terrible one! A good night's sleep doesn't just happen. You need to prepare for it.  First, go to bed at the same time every day, and get up at the same time. If you haven't gotten a good night's sleep, don't oversleep the next morning. Get up at your regular time. Sleeping late for just a couple of days can change your body clock to a different cycle. You don't want that if you have a set daily schedule! Also, avoid big meals at night.  Your stomach works hard to digest those fatty foods, and that may keep you up. Your body produces a chemical called melatonin (褐黑色素) that helps you sleep. Light affects the amount of melatonin your body makes . So at night turn off your TV and computer. Also, don't read from a backlit device like an iPad. Some scientists think that the light from those devices stops your body from making melatonin. Maybe you can't sleep or you wake up in the middle of the night.  Get up and do something relaxing elsewhere. Then go back to bed when you bed when you-feel sleepy. If you worry a lot, make a list of things you need to do the next day. Do that an hour before bed. That way you get your worrying out of the way before you go to bed. A. It produces more in the evening and less in the daytime. B. Don't just lie in bed. C. So stay away from smart phones and iPads. D. Various experts have given tips to help. E. You'll be able to face a new day after a good night's sleep. F. So turn those screens off at least one hour before bedtime. G. Eating heavy, rich food within two hours of bedtime can keep you awake. 答案：【1】D【2】G【3】A【4】C【5】B
