Accidents often happen. It's necessary for us to remember these tips.

On your way home or to school: Wait for the green traffic light, and look left and right before you cross the road. If you see a car coming, don't cross until it really stops.

At school: Never run around too fast at school. When students around you begin to push, try to hold something.  If you fall down in a crowed (拥挤的) place, cover your head with both hands.

When there's a fire: Keep quiet and leave quickly. Use a piece of wet cloth to cover your mouth and nose so that you don't breathe in smoke. If your clothes catch fire, drop to the ground and roll (滚动) from side to side to put out the fire.

For eating: Wash fruit like apples or pears carefully before you eat it. And if your food looks or smells bad, don't eat it.

About strange invitations: If an Internet friend asks to meet you, tell your parents about it. Don't go alone.
