How can we protect ourselves?

Self-protection is one of the most important skills for teenagers.Here are some of my suggestions about how to protect ourselves.

First, we should be careful to make friends, especially when we surf the Internet. Second, if we are in danger, we must call the police for help in time so that we can keep ourselves safe. Also, we should eat healthy food rather than junk food. For example, we are supposed to have as many fruits and vegetables as possible in our lives. Besides, we should avoid pushing when we go upstairs or downstairs at school. At last, we must remember it's dangerous to swim alone. Please never do it.

All in all, we need to learn how to protect ourselves and stay away from danger.

Dear teachers and fellow students,

I am very glad to give a speech on Families and Health here today. I think health is important to every family. In my family, there is a big problem of health-my parents and I are all very fat.

There are three reasons for this problem. First, we are all very busy, so we don't have time to exercise. Second, we usually have unhealthy food like hamburgers when we are hungry. Besides, we often stay up too late. 

In order to solve this problem, I think we must do sports. For example, we can walk home every day. We should eat healthy food. What's more, we should sleep early to have enough rest and energy.

That's all for my speech. Thanks for listening!
