2、要阅读下面短文,请完成短文后的2项测试任务:(1)从第16~20题后所给的6个选项中为第①-⑤段每段选择1个正确的小标题; Energy Cycle ❶Do you find getting up in the morning so difficult that it's painful? This might be called lazi- ness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle. ❷During the hours when you labor through your work you may say that you're "hot" That's true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the morning. For others it comes in the afternoon or evening. ❸No one has discovered why this is so but it leads to such familiar monologues(自言自语) Get up, John! You’ll be late for work again! The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has. ❹You can' t change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract (对抗)your cycle to some extent by habitually staying up later than you want to. If our energy is low in the morning but you have an important job to do early in the day, rise before your usual hour This won't' change your cycle, but you’ll get up steam(鼓起干劲)and work better at your low point. ❺Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours. 11. Paragraph❶ 12. Paragraph❷ 13. Paragraph❸ 14. Paragraph❹ 15.
