为保学生睡眠美国中学推迟上课

New evidence suggests that later high school starts have widespread benefits. Researchers at the University of Minnesota, funded by the Centers for Disease Control and Prevention, studied eight high schools in three states before and after they moved to later start times in recent years. In results released Wednesday they found that the later a school’s start time, the better off the students were on many measures, including mental health, car crash rates, attendance and, in some schools, grades and standardized test scores.

新的证据表明，推迟高中上课时间可以带来广泛的效益。在美国疾病控制和预防中心(Centers for Disease Control and Prevention)的资助下，美国明尼苏达大学(University of Minnesota)的科学家们研究了三个州的八所高中在近几年推迟上课时间的前后，学生们出现了哪些变化。他们在周三公布的研究结果显示：高中上课时间越晚，学生们在诸多指标（心理健康、车祸率、出勤率等，在某些学校里甚至还包括成绩和标准化考试分数）方面的改善越大。

Dr. Elizabeth Miller, chief of adolescent medicine at Children’s Hospital of Pittsburgh, who was not involved in the research, noted that the study was not a randomized controlled trial, which would have compared schools that had changed times with similar schools that had not. But she said its methods were pragmatic and its findings promising.
