　　我们缘何剥夺孩子们的睡眠?

　　Daylight is at a premium these days, and if your family is anything like ours, your teenagers are having a hard time getting out of bed in the morning. “Delayed sleep phase” is what affects them: the maddening shift in circadian rhythms that causes adolescents to fall asleep and awake at ever-later hours. Adolescents need an average of 9.25 hours of sleep per night to support their developing brains, which are exploding at a rate akin to infancy. But we treat access to sleep as if it were an illegal drug, commonly requiring teens to start school at 7:00 a.m. or earlier.

　　This puts students at a serious disadvantage. Numerous studies show that later start times are associated with lower rates of obesity, fewer car accidents and lower drop-out rates, as well as improved academic performance. In one study, shifting the start time from 7:20 to 8:40 a.m. significantly reduced depression as well. A few districts have shifted start times successfully, so why hasn’t the practice been adopted more widely despite overwhelming scientific evidence?

　　There are all sort of logistical excuses: delaying start times means parents might not be able to get to work as early; bus schedules would have to be shifted; a later school day would interfere with sports games and practices; teenagers would get home from school later, which would reduce family time.

　　But our inability to change start times is also illustrative of a larger pattern of neglecting the wellbeing and potential of our young people. We know, for example, that playtime and music increase cognitive development; yet school systems nationwide have dramatically slashed budgets for those critical activities. We know that children are sickened by junk food; yet we peddle unhealthy snacks in school cafeterias — and Congress just voted down proposed changes to the school lunch program that would require including fruits and green vegetables. We know that American teachers are poorly paid and supervised compared to teachers in many other countries; yet teacher-blaming is a favorite pastime.

　　On the sleep issue, like so many things related to children, adults often assume that there are impossible tradeoffs: if we “coddle” students by giving them adequate sleep, they might lose their competitive edge. Perhaps this is why, when an online petition was recently launched on the White House website requesting federal action to delay start times for teenagers, it didn’t meet the threshold of 5,000 signatures to merit an official response.

　　Making the switch would require collective action: we’d all have to make the switch together. Until the late 1960’s, the people of Sweden all drove on the left side of the road, like they do in England today. Then, one day, overnight, all the road signs in Sweden were changed, and everyone — together — started driving on the right side of the road. There were very few accidents and many benefits. Any major change in the social status quo is hard, but it is not impossible, and it often needs to be dramatic.

　　付出会有回报，提高需要努力，小编希望每一位决定了考研的考生都能够坚定自己的目标，并为实现目标努力奋斗，坚持不懈，只有这样才能收获丰厚的果实。2015年考研圆梦，大家一起努力。
