2007年12月英语四级阅读专项训练（四）

参考答案及解析:

Questions 31 to 35 are based on the following passage:

       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 explanation. He has proved that everyone has a daily energy cycle.

       注：1.第一句提出现象，后面跟着对现象的解释，这种解释一般是考点

               2.but  转折词和 might  虚拟语气都表达作者负态度

           3.最后一句话 he has proved... 主题句

       During 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 forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues (自言自语) as: '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.

       注：1.peak 顶峰，高峰

          2.forenoon 上午

      You 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 your 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.
