Question

【題目】Many people now have problems with sleep. Drinking milk is helpful. 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.

【3】A

【4】D

【解析】

試題分析：本文講述了研究發(fā)現(xiàn)：在晚上擠的牛奶更能促進(jìn)睡眠，并分析了原因。

【1】B 推理判斷題。根據(jù)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，那些被喂含有10倍褪黑激素的晚上牛奶的那些老鼠比喂給白天收的牛奶的老鼠更不活躍，更不焦慮；故推斷被喂給白天牛奶的老鼠更焦慮。故選B。

【2】D 推理判斷題。根據(jù)第六段中taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.可知，melatonin可以用于安眠藥，故選D項(xiàng)。

【3】A 主旨大意題。根據(jù)全文內(nèi)容以及第一段最后一句But now a study has found it really does help people nod off—if it is milked from a cow at night.可知，本文主要講述研究者發(fā)現(xiàn)晚上牛奶包含更多的褪黑激素，而這可以促進(jìn)人們的睡眠。故選A項(xiàng)。

【4】D 推理判斷題。根據(jù)前三段But now a study has found it really does help people nod off—if it is milked from a cow at night.一項(xiàng)研究表明……；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.研究者已經(jīng)發(fā)現(xiàn)晚上牛奶包含更多的褪黑激素，……； 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.來(lái)自漢城的研究者……。故作者是通過(guò)提供研究結(jié)果來(lái)支持文章主題的。故選D。

【名師點(diǎn)撥】

抓住文章主線(xiàn)和關(guān)鍵詞語(yǔ)，歸納文章中心

要注意不是所有的段落都有主題句，有時(shí)主題句暗含在句中。閱讀這樣的文章，就需要自己根據(jù)文章的細(xì)節(jié)來(lái)分析，概括出段落的主題，從而推導(dǎo)出文章的主旨。分析的方法是：先弄清該段落主要講了哪幾方面的內(nèi)容，這些內(nèi)容在邏輯上有什么聯(lián)系，然后加以歸納形成主題。比如第14小題A主旨大意題。根據(jù)第二段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. 研究者已經(jīng)發(fā)現(xiàn)晚上牛奶包含更多的褪黑激素，這已經(jīng)被證明能幫助人們感到困倦和減少焦慮�？芍狝項(xiàng)符合題意。
