Why Do People Take Naps? Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time — about eight hours after you wake up — your body temperature goes down. This is what makes you slow down and feel sleepy. 你有时会在下午早些时候感到有点疲倦和困倦吗？许多人在午饭后都有这种感觉。他们可能认为吃午饭是困倦的原因。或者，在夏天，他们可能认为是由于天气炎热。然而，真正的原因在他们的身体里。大约在你醒来8小时后的那个时候，你的体温会下降。这就是让你慢下来并感到困倦的原因。 Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later. 科学家们在没有昼夜之分的实验中对睡眠习惯进行了测试，实验参与者几乎总是遵循相似的睡眠模式。他们睡了很长一段时间，然后大约8小时后又睡了很短的一段时间。 In many parts of the world, people take naps in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. 世界上许多地方的人们会在中午时小睡。在气候较为温暖的地方尤其如此，那里刚到下午时的高温使人们很难进行工作。 Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from problems such as heart disease. 研究人员现在认为，在任何气候条件下，午睡对每个人都是有好处的。每天午睡使人的身心得到更充分的休息，因此整体上有益于健康。在有午睡传统的国家，人们患心脏病等疾病的几率往往较低。 Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! 不幸的是，许多上班族没有时间午睡。虽然医生可能会建议员工午睡，但雇主不允许！ If you do have the chance, however, here are a few tips about making the most of your nap. 不过，如果你真的有机会午睡，这里有一些关于充分利用午睡时间的建议。 Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap — even ten minutes of sleep can be helpful. 记住，午睡的最佳时间是起床后8小时左右。白天太晚午睡的话可能只会让你觉得更累更困。如果你睡得太久也会发生这种情况。如果你没有足够的时间午睡，试着打个小盹———即使是10分钟的睡眠也是有帮助的。 【读后习题】 According to the text, why do people feel sleepy in the early afternoon? 正确答案 C A.
