Dear classmates,

May I have your attention, please?

I notice that some of us spend most of our time doing our lessons, neglecting to take physical exercise. However, I think it is important to take regular exercise. For one thing, it can help us remain in good shape and stay away from disease. For another thing, it can contribute to decrease of the pressure from study, preventing depression.

Here are two tips for you: first of all, set aside some time for physical exercise every day. Nothing is more important than good health. Second, try to exercise with your good friends so that you can have fun while working out.

Whatever we want to become in the future, we should keep fit right now. So let’s make it a rule to take physical exercise every day.

That’s all. Thank you!
