题目

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 How to Sleep Better     If you're having trouble getting good sleep through the night (turning, waking up more than once, for example), this text will tell you what you can do to ensure a peaceful night's sleep.     1 Get up on time. Changing your sleeping time by more than an hour can severely disturb (干扰) your sleep quality.  For example, if you normally wake up at 6 am on weekdays to get to work, you might go to bed around 10 pm, because that's when you start to feel sleepy, and it's also a good time to ensure 8 hours of sleep. If, on the weekend, you sleep until 9 am, you probably won't be able to fall asleep that night until 1 am.     2  Wait at least three hours after dinner before going to sleep. Digestion(消化) slows down while asleep, and a full stomach may interrupt(打搅) sleep. Similarly, you should avoid going to bed on an empty stomach, as a completely empty stomach may equally disturb your sleeping patterns(模式).     3  Exposure(暴露) to light during the time when you're supposed to be sleeping can disrupt(扰乱) your body's internal clock. Turn your light off, or use a very dim night light. They include windows, LED clocks, computer lights and cable boxes.     4 Change your sleeping position. You may think that it's impossible to control what position you sleep in since you don't fully understand what you are doing, but it is possible and it can make a big difference. A. Try to avoid all sources of light. B. Keep the room as dark as possible. C. Make note of unusual circumstances (状况). D. Be mindful of what you eat or drink before bed. E. Sleep is considered to be adequate only when there is no daytime sleepiness. F. In other words, sudden change of sleeping time will affect your “biological(生物的) clock”. G. If you wake up in the middle of the night, make an effort to have a comfortable position. 答案：【1】F【2】D【3】B【4】A【5】G
