本课您将学到：军队词语分级别，表达你的兴趣，like和前缀 春日不是读书天，夏日绵绵正好眠你能抵抗瞌睡虫的袭击吗？喝咖啡已经落伍了，看看今天的科学新发现吧！ To make the most of your time, you should go to bed late and rise（起床） early. But that is conventional wisdom. The future may be different because scientists are doing what they can to get rid of our need for sleep. Researchers（研究人员） have been testing a new drug（药） that can keep people awake for days. The drug is called modafinil and, unlike other stimulants（兴奋剂）, it has no side effects. 以前，人们都用咖啡因来提神，虽然有效果但持续时间太短，而且会使人焦躁不安，没有办法真正提高工作效率。而这种新药据说直接作用于脑部，可使使用者连续数日保持自然的思维敏捷的感觉。 The U.S. military is interested in this type of drug for its soldiers. It would be advantageous to have pilots and fighters who could function（工作、运行） without sleep. 不知道这个世界会不会因此而多了几场战争呢？ 「读书笔记」 make在这里是利用的意思，要想最大程度的利用你的时间，（To make the most of your time）你就应该晚睡早起。（you should go to bed late and rise early）不过那都是传统的看法，（that is conventional wisdom）未来或许会有所不同，（The future may be different）因为科学家们正在竭尽全力（scientists are doing what they can）消除我们对睡眠的要求。（注意：这里的what they can是我们以前讲过的名词从句，还记得吗？） |
