Bicycle Helmets

Tom, a friend of mine, a college student, loves riding his bicycle at weekends. He especially enjoys taking long rides in the city. To my surprise, I found he never wears a helmet but it is very dangerous!

It is not always easy to get a friend to wear a bicycle helmet. Be patient! Give your friend time to come to his or her own decision about wearing one. Invite your friend to take a bicycle ride with you. Without saying anything, put your helmet on quietly. If you stop at a store during your bike ride, keep your helmet on. This will send a message that you are comfortable wearing a helmet both on and off your bike. If you remove it too quickly, your friend may think wearing a helmet is not very nice.

Each person needs to reach his or her own conclusions about safety and how to protect the body.

1. You should decide for yourself to wear or not to wear a bicycle helmet. ___T___

2. Tom goes to university by bike. ______

3. He loves riding in the country. ______

4. Riding a bicycle without a helmet is very dangerous. ______

5. Bicycle helmets are not expensive. ______

6. If you set an example it’ll help your friend start wearing a bicycle helmet. _______
