5.A warm drink of milk before bed has long been the best choice for those wanting a good night's sleep.But now a study has found it really does help people nod off-if it is milked from a cow at night.Researchers have discovered that"night milk"contains more melatonin(褪黑激素),which has been proven to help people feel sleepy and reduce anxiety.
The study,by researchers from Seoul,South Korea,involved mice being fed with dried milk powder made from cows milked both during the day and at night.
Those given night milk,which contained 10 times the amount of melatonin,were less active and less anxious than those fed with the milk collected during daytime,according to the study published in The Journal of Medicinal Food.
Night milk quickened the start of sleep and caused the mice to sleep longer.
While the effect of cows milk harvested at different time has not been tested on humans up to now,taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.
Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content,which helps people to relax.
Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening.The more fat you take in before bedtime,the greater burden you will put on your body at night.

分析 最新的科研成果表明--晚上采集的牛奶含有更多的褪黑激素(melatonin),摄入者能更好地睡眠以及睡更长的时间.在结论之前已经经过了白鼠测试--摄入晚上采集的牛奶的老鼠比白天采集的牛奶的老鼠安静(不活跃),睡得更香,时间更长.这个研究成果已经用来帮助有睡眠问题的人--注射褪黑激素针剂以帮助睡眠.
解答 答案:BDAD
32.B 细节推理题 第四段中"Those given night milk,which contained 10 times the amount of melatonin,were less active and less anxious than those fed with the milk collected during daytime"说明:那些被喂了夜间含有十倍褪黑激素奶的老鼠,要比吃了白天收集的奶的老鼠,更不活跃,也更不焦虑.也就是说,被喂食了日间奶的老鼠会更活跃,更焦虑些;故选B
33.D 判断推理题. A项错误,并非是给老鼠注射了十次,而是晚上采集的牛奶含有的褪黑激素是白天的10倍;B,褪黑激素能让人降低活跃度;C 并非含有大量的褪黑激素,文章中也没有提到;D项正确.
34.A 内容归纳题.本文主要讲的是晚上采集的牛奶和睡眠的关系.晚上产的牛奶含有更多的褪黑激素,而褪黑激素能帮助睡眠.因此选A.
35.D 写作结构题.本文主题是--晚上采集的牛奶和睡眠的关系.晚上产的牛奶含有更多的褪黑激素,而褪黑激素能帮助睡眠.通过举例老鼠实验进行有力的论证.
