D 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 melat onin(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 sugarfree and additivefree with nutritionists remending 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. 32. 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 33. Which of the following is true of melatonin according to the text? A. It’s been tested on mice for ten times. B. It can make people more energetic. C. It exists in milk in great amount. D. It’s used in sleeping drugs. 34. What can be a suitable title for the text? A. Night Milk and Sleep B. Fat Sugar and Health C. An Experiment on Mice D. Milk Drinking and Health 35. How does the author support the theme of the text? A. By giving examples. B. By stating arguments. C. By explaining statistical data. D. By providing research results. 第二节(共 5小题,每小题 2分,满分 10分) 根据短文内容,从短文后的选项中选出能填入空向处的最佳选项。 选项中有两项为多余选项。 The Inter has opened up a whole new online world for us to meet, chat and go where we’ve never been before .
