Why are Children Lacking Sleep ?(为何年少总是缺觉?)

   Why are Children Lacking Sleep ?
      Just how important is school nowadays? Teachers often complain that homework is not done well and that students are often arriving at school delayed and yawning through lack of sleep.
     There are,  it  seems,  two  main explanations for this. Firstly, many young children stay up late to watch TV programmes suitable for them, which may finish as late as 8:00. No child wants to admit
not having seen what everybody else has.
     Secondly, a growing number of older children, particularly those approaching school-leaving age are taking up parttime evening or weekend work. They feel that working experience, not academic qualification will help them find jobs on leaving school. One can sympathize with both groups of children but it doesn't make a teacher's life any easier.

为何年少总是缺觉?
    如今学校有多重要?老师经常抱怨学生们，不是作业做得不好，就是经常上课迟到，并因为缺觉而呵欠连天。
    看起来这种现象主要有两种解释。首先，许多小孩子看电视熬夜到很晚，那些适合他们的节目也许要到八点那么晚才能结束。没有孩子愿意承认自己没看过别人都看过
的节目。
    其次，越来越多稍大点的孩子，尤其是那些接近离校年龄的孩子，开始在晚上或周末做兼职工作。他们觉得毕业时能帮他们找到工作的是工作经历而不是学术资历。我们可以对这两类孩子表示同情，但是这无法使老师的日子更好过些。
