It is reported that school accidents, such as food poisoning (食物中毒), fires, electricity and traffic, kill more primary and middle school students than anything else. So we must learn how to protect ourselves better. Here are some tips for keeping safety in mind every day.

On our way home or to school: Wait for the green traffic light, and look left and right before we cross the road. We’d better wear bright-color clothes, so the drivers can see us easily. Don’t believe strange people in the street.

At school: When students around us begin to push each other, we need to stand still and try to hold onto something, or stay in a corner until the crowd(人群) leaves. If we fall down in a moving crowd, use both hands to cover the head. Lean(傾斜) to one side, curl up (蜷縮) our body and bend (彎曲) the legs.

In a fire: Stay calm. Leave the classroom quickly under the instructions of the teachers. Smoke can be more dangerous than fire, so use a piece of cloth to cover our mouth and nose. What will we do if the clothes burn? Remember not to run! Drop and fall to the ground. Then roll! It will make the fire go out(熄滅).

For eating: Wash fruits carefully before eating them. Check the expiration dates (保質(zhì)期) on the packages of the snacks, and if it smells bad, don’t eat it.
