分析 本文主要写了不同年龄段的人们对于睡眠时间的不同要求,并告诉人们如何拥有一个好的睡眠.
解答 25.答案是ought to.考查情态动词,根据句意"儿童应该睡到十到十二个小时",ought to 是情态动词"理应,应当",所以答案是ought to.
26.答案是a 考查冠词,根据句意"一个青少年的睡眠大约要九个小时",这里是泛指,所以用不定冠词a.
27.答案是others.从文中可知,成年人中大部分需要七到八个小时,一些睡得更多些,其他的成年人四个小时就可以了,some…others,一些…其他的,所以答案是others.
28.答案是having.考查非谓语,本句中缺少主语,拥有一个舒服的地方睡觉,所以用动名词做主语,故答案是having.
29.答案是although.考查连词,"尽管上床之前喝咖啡不是很好,但是一杯热的饮料可以帮助睡眠",although引导让步状语从句"尽管…但是…",所以答案是although.
30.答案是if.考查连词,根据句意"如果你去远方旅游的话",if引导条件状语从句"如果",所以答案是if.
31.答案是to go.考查固定结构,try to do sth.是英语的固定搭配"设法做某事",所以答案是to go.
32.答案是relaxed.考查形容词,feel是个系动词后跟形容词作表语,relaxed是形容词"放松的,自在的",所以答案是relaxed.
