优秀范文
Hello everyone!I'm Li hua. Today, I'm very happy to share my healthy lifestyle with all of you.As a middle school student, I'm busy with my studies at school. But in my free time, I play some sports every day, such as running and playing ping pong. On weekdays, I always go to bed early and get up early. And before going to bed, I usually read for a while. It helps me with my studies. As for my eating habits, I often eat fruit and vegetables. However, I never eat potato chips or drink coffee. In my eyes, they are not good for my health. It's important for us to have a healthy lifestyle. It is good for our studies and everyday lives.That's all for my speech. Thank you for your listening.
Yours,
Li Hua
