Question

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 times 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.

主旨大意题的解题思路与应试技巧

做这类题时常用略读法。快速阅读文章找出各个段落的主题句。把各个段落的主题句联系起来着眼于全文结构安排，了解文章的重心，就能概括出文章的中心。文章的标题是中心思想最精炼的表达形式，选择的标题意义范围要能涵盖全文，不能太大也不能太小。命题者在出这类题时，常常利用生活常识编造干扰项，把文中的细节当主旨，利用局部信息编造干扰项，编制超出文章范围的标题或不能涵盖文章中心意义的标题来考查考生的理解程度，考生要特别留意。

概括主旨的方法是：先看首尾或各段开头再看全文找主题句，若无明显主题句，就通过关键词句来概括(如议论文中寻找表达作者观点态度的词句，记叙文寻找概括情节和中心的动词或反映人物特点的形容词。) 。文中出现两种或两种以上的不同观点时，务必牢记作者的观点才是体现全文中心的。此时，要注意一些转折词，如but, yet, however, although, in spite of, by contrast, on the contrary等。当文章中表示相反的观点时，往往用到这些词。答题时要弄清哪个是作者的观点，排除迷惑性信息，准确归纳主旨大意。
