题目：
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 labour 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. 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.Get 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. 1.If a person finds getting up early a problem,most probably ________. A.he is a lazy person B.he refuses to follow his own energy cycle C.he is not sure when his energy is low D.he is at his peak in the afternoon or evening 2.Which of the following may lead to family quarrels according to the passage? A.Unawareness of energy cycles. B.Familiar monologues. C.A change in a family member's energy cycle.

A.change his energy cycle B.get up earlier than usual C.overcome his laziness D.go to bed earlier 4.You are advised to rise with a yawn and stretch because it will ________. A.help to keep your energy for the day's work B.help you to control your temper early in the day C.enable you to concentrate on your routine work D.keep your energy cycle under control all day 答案： 1-4:DABA 解析： 健康环保累阅读概念： 健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、说明文、议论文和各种应用文。 健康环保类文章阅读技巧： 健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考，理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文，从结构上看大致可分为三个部分： 第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容； 第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明； 第三部分是结尾段，对文章的主题进行归纳总结。这类文章多用一般现在时，而且一般多使用客观性词语表述。有时为了强调客观性，也常使用被动语态。 从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节，很多同学对此类文章感到费解。但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题。 【阅读策略】 1、概要(Summarizing)： 阅完材料后，将所阅材料浓缩，摘要，做出所阅材料的书面或口头梗概。 2、组织(Organization)： 阅读后根据阅读内容，识别观点、人物、事件之间的关系以及文章的结构关系。如：时间关系、比较或对比关系、相关关系及因果关系等。
