Section B 课本语篇过关
第五中学的学生们在课余时间做什么？
上个月，我们询问了我们的学生一些有关课余活动的问题。我们的问题是有关锻炼、使用网络，以及看电视。以下是所获得的结果。
我们发现我们的学生中只有百分之十五每天锻炼。百分之四十五的学生一周锻炼四至六次。百分之二十的学生一周只锻炼一至三。还有百分之二十的学生根本就不锻炼！
我们都知道许多学生经常上网，但是让我们惊讶的是，有百分之九十的人每天使用网络，另外百分之十的学生每周至少使用网络三至四次。绝大多数学生上网娱乐，并非为了做功课。
对我们提出的有关看电视的问题的回答也颇有意思。只有百分之二的学生一周看一直三次电视，百分之十三的人一星期看四至六次电视。另外百分之八十五的人每天都看电视！虽然许多学生喜欢观看体育节目，但游戏类节目却是最受欢迎的。
通过使用网络或观看游戏类节目来放松是件好事，但我们认为最佳的放松方式是通过锻炼。它有益于身心的健康。诸如参加体育运动这样的锻炼方式不但有趣，而且当你和朋友、家人一起运动时，你们还可以共度时光。请记住：”旧习难改。”所以赶快锻炼起来，不要等到来不及了。
