【答案】Dear fellow students，
According to the World Health Organization（WHO），there are about 80% teenagers around the world lacking exercising. And it will lead to our health problem.
In my opinion， the reason why most of us think exercising is a waste of time is that we are having much homework in high school. What's more， we prefer phones to sports. However， sports can strengthen our body and make us energetic， which is beneficial to our study. So， I call on  all of us to 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 on your plan， otherwise you cannot gain any effect. Anyhow， I hope all of us can change our mind and spend some time exercising.
That's all. Thank you for listening!
