Do you find getting up in the morning so difficult that it’s painful? This might be called laziness, but Dr. Kleitman has a new     36    . He has proved that everyone has a daily energy cycle.
During the hours when you labour through your work, you     37     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     38    . For some people the peak es during the forenoon. For others it es in the afternoon or evening. No one has discovered     39     this is so , but it leads to such familiar monologues （自言自语）    40     “Get up , John ! You’ll be late for work again!” The     41     explanation to the trouble is that John is at his temperature—and —energy peak in the evening. Much family quarrelling     42     when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.
You can’t change your     43    , but you can make your life     44     it better. Habit can help. Dr. Kleitman believes. Maybe you’re sleepy in the evening but feel you must stay up late     45    . Counteract （打乱）your cycle to some extent by     46     staying up later than you want to . If your energy is     47     in the morning but you have an important job to do early in the day,     48     before your usual hour. This won’t change your cycle, but you’ll get up steam(打起精神) and work better     49    .
Get off to a slow start     50     saves your energy. Get up with a yawn （呵欠）and     51     . Sit on the edge of the bed a minute before     52     on the floor. Avoid the     53     search for clean clothes by laying them out     54    . Whenever possible , do routine （常规的）work in the afternoon and save tasks     55     more energy for your sharper hours .
