     One afternoon Bob and Jane were walking along a quiet street when they heard a big noise from the

street corner. They ran there and found that a small car had knocked into the side of a truck. Both the

car driver and the truck driver were hurt.

   "Bob," said Jane, "run back down the road to M r s Day's house. Ask her to call the police and the

ambulance(救护车) . Hurry. I'll stay here. "

    Bob went off as fast as he could. There was nothing Jane could do but wait. She knew that when

people were hurt in an accident, they shouldn't be moved.

    It wasn't long before the police car and the ambulance arrived. The policemen got the car door open

and moved the man out. Then they got the truck driver out. Luckily, the men weren't badly hurt, but they

were both taken to hospital. The policemen thanked Bob and Jane. "You were very good to act so

quickly when you saw the accident. Thank you for your help. "
