I think the teeagers shouldn't stay up too late to study because it is bad for their health.They need to sleep at least eight hours a day.Besides it isn't effect to study too late,they need to keep their brain and mind clear and fresh.When they go to bed too late,they will feel tired in class the next day.So they can't concentrate better.
Today more and more students are inclined to stay up at night.They enjoy the night so much that they don't go to bed until deep into the night or even until the next morning.Hower that would do harm to their health.Students who usually stay up can get tired the next day and they often sleep in class.They can't listen to the teachers heart and soul.As time goes on,they will do bad in their study ,and will be poor health.For these reasons,I would like to advise those students who are staying up not to do that again!You should go to bed before 11 in the evening.Will you take my advice?
With the College Entrance Examinations approaching , the students of Senior Three are focusing much more on studying. Many of them even begin to stay up studying. A heated discussion was held to argue about the advantages and disadvantages of it.
Some students have their own reasons for studying late into night. Firstly, the quietness in the night will result in better effectiveness. Besides,
the examinations are only 200 days away so it's high time they made good use of every minute. What’s more, seeing others studying so hard, they will feel anxious if they don’t take action.
Some others, however, hold the opposite view, saying that a sensible senior student must know how to balance his time between study and leisure. As everyone knows, staying up late will naturally affect the next day's performance in class.
As far as I’m concerned, different people have different habits. If you can hold it, it’s your own business when to study and when to sleep.
