Cloze 20
     Do you find getting up in the morning so difficult that it’s painful? This 1 called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy 2 .
     During the hours when you 3 your work you may say that you’re ‘hot’. That’s true. The time of day when you feel most 4 is when your cycle of body temperature is 5 its peak. For some people the peak comes during the forenoon. For 6 it comes in the afternoon or evening. No one has discovered why this is so, but it 7 such familiar monologues (自言自語(yǔ)) as: Get up John! You’ll be late for work again! The possible explanation to the trouble is that John is at his 8 and energy peak in the evening, 9 family quarrelling ends when husbands and wives realize 10 these energy cycles mean, and which cycle each member of the 11 has.
     You can’t change your energy cycle, but you can learn to make your life 12 it better. 13 can help, Dr. Kieitman believes. Maybe you’re sleepy in the evening but feel you must 14 late anyway. Counteract (對(duì)換) your cycle 15 by habitually staying up late than you want to. If your energy is low in the morning but you have an important job to do 16 in the day, 17 before your usual hour. This won’t change your cycle, but you’ll get up steam and work better at your low point. Whenever possible, do 18 work in the afternoon and 19 tasks requiring more energy or concentration for you 20 hours.
