    Self-protection is one of most important skills for us teenagers. But how do we protect themselves? Now let me share my ideas to you.

    First, I always obey the traffic rules and I never ran the red light. When the traffic light is red, I won't go as it turns green. I always cross the zebra walk because of it is safe. Second, I often eat the food what is healthy and safe. Eat too much fast food will be harmful to my health. Third, I never meet stranger alone, especially friends whom I make on the Internet.

    In short, if we obey the rules and take care of ourselves, we will grow up happy.
