17．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．
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 the 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 （自言自語） as John talks to himself："Get up，John!You'll be late for work again!"The possible explanation for 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．
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．Adjust your cycle to some extent by 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 （打起精神） and work better at your low point．
Begin with a slow start which saves your energy．Get up with a slow 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 usual work in the afternoon and spend time doing important work for your high peak hours．

32．答案：C 考查細(xì)節(jié)推理．根據(jù)第二段"The possible explanation for the trouble is that John is at his temperature-and-energy peak in the evening．"可知，John 早晨起不來是因?yàn)樗哪芰吭诎磉_(dá)到高峰，可以推斷早上起床困難是因?yàn)樵缟咸幱谀芰康凸龋?br />33．答案：C 考查細(xì)節(jié)推斷．由第二段最后一句"Much family quarrelling ends when husbands and wives realize what these energy cycles mean，and which cycle each member of the family has．"可知家庭的爭吵可能源于夫妻雙方?jīng)]有意識(shí)到雙方energy cycles的不同．正確答案應(yīng)是C．
34．答案：D 考查細(xì)節(jié)分析．根據(jù)第三段"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 （打起精神） and work better at your low point．"可知，D為正確答案．
35．答案：B 考查推斷能力．根據(jù)倒數(shù)第二段和最后一段"Begin with a slow start which saves your energy．Get up with a slow yawn and stretch．"可知，早起放慢動(dòng)作是為了白天的工作節(jié)省能量，所以正確答案為B．
