Some advice(忠告)：
⑴ Always play in a safe place. A park is a safe place because there are no cars or trucks. But do not talk to anyone you do not know. Never go with a stranger into a motor car.
⑵ Before crossing the road， stop and look both ways. Look left， look right， look left again.
⑶ Keep away from houses or building that are being built or knocked down. Something might fall on your head， or you might cut yourself on broken grass.
⑷ Medicines or pills can be dangerous. Never swallow（吞下）any pills or medicines you find in the cupboard.
⑸ Wear a life jacket whenever you go out in a boat. Even if you are not in the open sea and the water is not deep， you should have your life jacket on. It's easy to fall out of a boat.
⑹ Do not put your head out of a car， bus or train. Many children have been killed by doing this.
