2.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 proved 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.

12.C 细节理解题.由第四段第一句"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"可知,那些喝了白天产的牛奶的老鼠比喝晚上产的牛奶的老鼠要更活跃和焦虑.故正确答案为C.
13.A 细节理解题.由第二段"Researchers have discovered that'night milk'contains more melatonin,which has been proven to help people feel sleepy and reduce anxiety"可知,褪黑色素可以使人有困意,因此可以用于安眠药中,A项正确.B项,"褪黑激素使得人们更加有能量",与文中所提到的褪黑激素使老鼠变得没有活力不符,B项错误;C项,"牛奶中有很多褪黑激素",由第三段第一句"Those given night milk,which contained 10 times the amount of melatonin"可知晚上产的牛奶中存在很多褪黑色素而不是所有牛奶,C项错误.D项,"褪黑激素在老鼠身上测试过10次",文章未提及,D项错误;故正确答案为A.
