How can we students keep ourselves safe? Here are some t   .
On your way home or to school: W   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 is really safe. Dress in bright colours, so the drivers can see you c  .
At school: When students around you begin to push, try to hold onto something, or stay in a safer corner. If you fall down in a crowded（拥挤的）place, cover your head with b   hands.
When there’s a fire: Stay c   and leave quickly. Use a piece of wet cloth to cover your mouth and nose so that you don’t take in s   . If your clothes catch fire, please drop to the ground and roll from side to side to put out the fire.
For eating: Wash fruit like apples or g  carefully before you eat them. Check the expiration dates（保质期）and if your food looks or smells t  , don’t eat it.
For riding on the escalator（自动扶梯）: Hold onto the handrails（扶手）. It is d   to run up and down on them. You may fall down because escalator steps（台阶）are not fit for
