Dear fellow students，

【答案】Dear fellow students，
According to the World Health Organization （ WHO），there are about 80% teenagers around the world lacking exercising.Absolutely，it will case severe health problems.In my opinion，we should pay more attention to that and exercise regularly every day.
As we all know，most of us think exercising is a waste of time for we are having much homework in high school.We prefer phones to sports.However，sports can strengthen our body and make us energetic，which is beneficial to our study.So，I wonder if all of you can make a plan for daily exercise after hearing my speech.You can choose a sport you like and make a reasonable time for doing it.Make sure you can insist otherwise you cannot gain the effect.Anyhow，I hope you can change your mind and spend more time exercising.
That's all.Thank you for listening !
