请以“The body clock "为题,参考下面提示,写一篇１２０－１５０词的英语短文,描述人体生物钟,并提供一些关于保护和调节生物钟的建议.生物钟的作用：对于人们的思想和行为有着巨大的影响和支配 正常的状况：身体健康,精神愉快,工作和学习效率就很高.生物钟紊乱：身体容易疲劳,情趣低落,甚至容易患各种病 保护与调节：不要熬夜,加强锻炼,有规律的学习,工作和生活

If you have ever flown across several tme zones, you must have experienced jet lag You arrived in a new time zone, but your body was still living on the time in the old time zone. You were wide-awake and ready for dinner in the middle of the night, and you wanted to sleep all day. People suffer from jet lag because all living things have a biological clock. Plants and animals are all in rhythm with the natural divisions of time —day and night and the seasons. Some French scientists did an experiment with honeybees. They put out sugar water every morning at 10:00 and at noon, and the bees came to drink the water at exactly the right time. Then the scientists put the sugar water in a room that was brightly lit 24 hours a day. They started putting the sugar water out at 8:00 p.m.It took the bees a week to find it at the different hour, but from then on they came to eat in the evening instead of in the morning. Later the scientists took the honeybees to New York. The bees came for the food at the time their bodies told them, only it was 3:00 p.m.New York time.Their bodies were still on Paris time. Humans, like other animals, have a biological clock that tells us when to sleep and eat.It causes other changes, too. Blood pressure is lower at night, the heartbeat is slower, and the body temperature is a little lower. The honeybees in the experiment reset their biological clock for different feeding hours. Humans do this, too. People who work at night learn to sleep during the day and eat at night. Students who fly halfway across the world to study in another country get used to the new time zone after a few days. Our bodies are controlled by a biological clock, but we can learn to reset it at a different time. 在网上看到一篇,觉得挺好的,给你看看吧
