【解题导语】 本文描述了一个普遍存在的现象。调查显示大部分青少年学生的睡眠时间不足这是导致他们学习成绩差的原因之一。1.解析:worse。考查比较级。这里与get older 相对应所以都应该用比较级的比较级是worse变得更糟糕”。故填worse。2.解析:problems。考查可数名词使用。problem是可数名词这里没有定冠词所以要用复数形式。故填problems。3.解析:asleep。考查固定短语。fall asleep“入睡;睡着”。故填asleep。4.解析:surprising。考查形容词。surprise 使吃惊;惊奇”主要用法有:(1)in surprise“惊奇地”;(2)by surprise“出其不意地”;(3)to one's surprise“使人吃惊的是”;surprised 吃惊的”一般修饰人如:be surprised to do; surprising也是形容词使人吃惊的”一般修饰物不足为奇”。故surprising。5.解析:unhappy。考查形容词。睡眠不足会导致nervous“紧张”这里与紧张是并列结构所以应该是一个消极词汇。故填unhappy。6.解析:following。考查形容词的使用。这里修饰的是名词things所以要填形容词。follow的形容词形式要加ing。故填following。7.解析:only。考查固定搭配的使用。后半句出现了but also所以这里应该是not only不仅……而且”。故填only。8.解析:it。考查代词的使用。make为动词为形容词中间缺少一个名词要用it指代睡觉。故填it。9.解析:to go。考查动词不定式的使用。get up to do something“起床做某事”。故填to go。10.解析:before。考查介词的使用。文章的意思是在睡前一小时不要做太兴奋的活动。故填before。书面表达假定你是李华暑假马上就要到了你的笔友Peter给你发邮件询问你的假My Plan of the Summer Holiday
