2.Willi around 100 students scheduled to be in that 9am Monday morning lecture,it is no surprise that almost 20 people actually make it to the class and only 10of them arc still awake after the first IS minutes; it is not even a surprise that most of them are still in their pyjamas (睡衣).Obviously,students are terrible at adjusting their sleep cycles to their daily schedule.All human beings possess a body clock.Along with other alerting (警报) systems,this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour.Typically,the preferred sleep/wake cycle is delayed in adolescents,which leads to many students not feeling sleepy until much later in the evenings.This typical sleep pattern is usually referred to as the"night owl"schedule of
This is opposed to the"early bird"schedule,and is a kind of disorder where the individual tends to stay up much past midnight.Such a person has great difficulty in waking up in the mornings.Research suggests that night owls feel most alert and function best in the evenings and at night.Research findings have shown that about 20percent of people can be classified as"night owls"and only 10percent can be classified as"early birds"-the other 70percent are in the middle.Although this is clearly not true for all students,for the ones who are true night owls this gives them an excellent excuse for missing their lectures which unfortunately fall before midday.

分析 本文是一篇说明文.以学生星期一早上课时很多学生难以将他们的睡眠周期调整到正常为例,只有20%的学生到,在上课15分钟后,仅有10%的学生还醒着,有人还穿着睡衣,学生还没有调整好自己的睡眠模式,说明学生不擅长调整自己的生物钟而去适应白天的学习,文章主要解释了晚上不困,白天困的"night owl"(夜猫)这一睡眠周期现象.
解答 43.C 推理判断题.文章第一段"it is no surprise that almost 20 people actually make it to the class and only 10 of them arc still awake after the first IS minutes;"及"Obviously,students are terrible at adjusting their sleep cycles to their daily schedule"可知,在星期一早上的课上只有20%的学生到位;在上课15分钟后还有10%的学生还醒着,甚至有人还穿着睡衣,学生还没有调整好自己的睡眠模式.故选C项.
44.D 细节理解题.根据第二段"Typically,the preferred sleep/wake cycle is delayed in adolescents …"可知,学生们对他们自己的睡眠模式不熟悉,没有能够恰当地去调整适应自己的生物钟,因而造成了睡眠问题,故选D项.
45.B 推理判断题.根据第三段中"Research findings have shown that about 20 percent of people can be classified as"night owls"and only 10 percent can be classified as"early birds"-the other 70 percent are in the middle"调查结果表明大约20%的人可归类为"猫头鹰"型,只有10%的人可以归为"早起"型.此处"classify"应为"归类,分类"等意思.把不同的人分为不同的类型.故选B项.
46.B 推理判断题.本文通过星期一早晨学生很难从原来的睡眠模式里转换调整例子引入,然后分析并介绍造成这种情况的原因,文章主要解释了晚上不困,白天困的"night owl"这一睡眠周期现象.故选B.
点评 解答细节理解题时,一个常用的方法就是运用定位法,即根据题干和选项中的关键词从原文中找到相关的句子,与选项进行比较从而确定答案;推理判断题既要求学生透过文章表面文字信息推测文章隐含意思,又要求学生对作者的态度、意图及文章细节的发展作正确的推理判断,力求从作者的角度去考虑,不要固守自己的看法或观点.
