According to a survey made last week, most middle school students only have an average of less than 7 hours’ sleep each night, much less than required. There are several reasons for this. First of all, the students are burdened with too much homework. Another important reason is that schools and parents pay less attention to their sleep. But, in fact, this will be harmful to their health. So we must take some measures to stop this. First, less homework should be given to the students by teachers or parents. Second, more attention should be paid to their health. Third, the living conditions for them should be improved.
