Quite some students are late for class recently, which arouses big concern from teachers. Our school organized a survey on "Why students are late for class" last week. The main reasons are as follows:
About 65% of the interviewers said that they went to bed very late at night because they spent time surfing on internet. Some said they needed to find some useful information for their lessons. About 20 % of the respondents said that they read novels from internet until late at night. The rest said that they played with their mobile phone when they stayed in bed and chatted with friends.
Staying up too late is the cause for being late for class. Students must come to realize the bad effect arising from it. It is unhealthy for youngsters not to sleep enough hours every day.
