  试题分析:本文属于说明文范畴。在文中作者通过介绍一堂课中学生迟到和准时到的情况,提出了学生不擅长调整自己的生物钟而去适应白天的学业安排。然后在文中分析了目前青少年睡眠存在的问题,提出了两种不同的睡眠模式,即“earlybird”(早起型)和“nightowl”(夜猫子型),并主要介绍了晚上不困,白天困的“nightowl”现象。

  1.考查主旨大意。在文章首段作者首先通过数字说明许多学生早晨不能准时起床的一种情况,然后用一句话Obviouslystudentsareterribleatadjustingtheirsleepcyclestotheirdailyschedule.来解释这种现象的原因,提出文章中心,然后围绕此中心展开行文,故答案选C。

  2.考查细节理解。根据第二段Typicallythepreferredsleep/wakecycleisdelayedinadolescents…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,故答案选D。

  3.考查词义推断。A批评;B分类;C组织;D命名。根据上文第三段末句Thistypicalsleeppatternisusuallyreferredtoasthe"nightowl"scheduleof和第四段首句Thisisopposedtothe"earlybird"schedule可知睡眠模式有两种,即”nightowl”和”earlybird”,而此处把20%归到nightowls类,由此判断该词意思为“分类”,选B。

  4.考查主旨要义。在文章开头介绍一堂课中学生的迟到和准时到的情况,提出了学生不擅长调整自己的生物钟而去适应白天的学业安排这一问题。然后在下文对此现象进行分析并介绍造成这种情况的原因,所以答案选B。A选项内容“人体生物钟的功能”,B选项“人体的睡眠行为”都比较片面,不能反应文章中心;而D选项“早起者的时间安排”在文中没有涉及。

  考点:

  考查社会生活类短文阅读。
