Ⅲ.阅读理解 [2023年·山东期中]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 does help people nod off(打瞌睡)—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 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 cow milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who have trouble falling asleep at night. Previous(以前的) studies have also shown that milk can be excellent for helping sleep because of the calcium content, which helps people to relax. 【语篇解读】　本文讲述了夜间挤的牛奶和睡眠的关系。夜间挤的牛奶包含更多的褪黑激素，这种物质可以帮助睡眠。 1．According to the text, the mice fed with daytime milk ________. A．started sleep more easily B．were more anxious C．were less active D．woke up later 答案与解析：B　推理判断题。根据第四段“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，喂夜间挤的牛奶的那些老鼠比喂白天挤的牛奶的老鼠活跃性要低，焦虑也少。故喂白天挤的牛奶的老鼠更焦虑，故选B。 2．Which of the following is true of melatonin according to the text?
