28、he text，the mice fed with daytime milk Astarted sleep more easilyBwere more anxiousCwere less activeDwoke up laterB细节理解题。由第四段中的信息Those given night milk.were less active and less anxious than those fed with the milk collected during daytime.可知，老鼠喝了白天挤的牛奶会更有活力，也更焦虑，故选B项。10Which of the following is tru

29、e of melatonin according to the text?AIts been tested on mice for ten times.BIt can make people more energetic.CIt exists in milk in great amount.DIts used in sleeping drugs.D推理判断题。文章中提到晚上挤的牛奶的褪黑激素含量是白天挤的牛奶的10倍，并不是说研究人员在老鼠身上测试了10次，所以A项错误；由第二段中的信息.help people feel sleepy and reduce anxiety.可知褪黑激素不可能使

30、人更加精力充沛，故排除B项；由第二段中的信息.“night milk”contains more melatonin.可知，并不是所有的牛奶中都含有大量的褪黑激素，故排除C项；由第六段中的信息taking melatonin drugs has been suggested to those who are struggling to fall asleep at night可知，褪黑激素被用于安眠药中，故D项正确。11What can be a suitable title for the text?ANight Milk and SleepBFat，Sugar and HealthCAn

31、Experiment on MiceDMilk Drinking and HealthA标题归纳题。作者在第一段就点明了文章要论述的对象晚上挤的牛奶。在接下来的几段中，作者通过研究人员在老鼠身上做的实验论证了晚上挤出的牛奶与睡眠的关系，所以最适合作文章标题的是A项。B项意为“脂肪、糖与健康”，C项意为“在老鼠身上做的一个实验”，D项意为“牛奶饮用与健康”，均与文章的主旨不符。12How does the author support the theme of the text?ABy giving examples.BBy stating arguments.CBy explaining statistical data.DBy providing research results.D推理判断题。文章的第二、三、四、五段都是讲研究人员的实验及其结果，所以作者是用研究人员的研究结果来支持论点的。文章中没有给出具体的例子，没有单纯地陈述论点，也没有解释统计数据，所以排除A、B、C三项，选D项。
