阅读理解 Sleeping in on Saturday after a few weeks of too little shuteye may feel refreshing,but it can give a falsesense of security.
New research shows longterm sleep loss cannot be cured that easily.Scientists researched the effects of
shortand longterm sleep loss and found that those who suffer longterm sleep loss may function normally so
on after waking up,but experience steadily slower reaction times as the day goes by,even if they had tried
to catch up the previous night.
The research has important safety significances in an increasingly busy society,not just for shiftworkers
but for the roughly one in six Americans who regularly get six hours or less of sleep a night.
"We know that staying awake 24 hours without sleep will affect your performance to do all sorts of
things,and this effect equals to drinking too much when driving," said lead researcher Dr Daniel Cohen of
Boston's Brigham and Women's Hospital. But when those who suffer longterm sleep loss become
allnighters,"the harm is increased ten times," Cohen said.
The National Institutes of Health says adults need seven hours to nine hours of sleep for good health.
Regularly getting too little sleep increases the risk of health problems,including memory impairment and a
weakened immune system.More immediately,too little sleep affects reaction times；sleepiness is to blame
for car crashes and other accidents.
It has critically important complicated and unexpected results for anyone who works "crazy hours" and
thinks they are performing fine with a few hours of weeknight sleep,said Harris,director at New York's
Montefiore Medical Center."Don't think you can just bank_up your sleep on the weekend,because it

【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。
【备考提醒】
为了保证较高准确率，建议同学们做好以下几点：
1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。
2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。
4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
