【答案】Dear fellow students，
In its first research report on global youth sports trends，the World Health Organization said that about 80% of teenagers around the world lack exercise，which will absolutely cause severe health problems.Therefore，we should attach great importance to it and have enough exercise.
One reason for the case is that many of us teenagers hold an opinion that exercising will cost us much time for we have much homework.Another reason is that nowadays，something such as a smartphone seems to be more appealing to us than exercise.
However，exercising enough is of great importance to our health.Considering our limited time，I recommend jogging to you，because jogging doesn't need any equipment and you can go jogging whenever and wherever.Of course，make sure you can insist，or you cannot gain the effect.Anyhow，I hope you can change your mind and act now.
That's all.Thank you for listening !
