根据短文内容判断下列句子的正误,正确的用“A”,错误的用“B”。

       One afternoon Bob and Jane walked in a long quiet street. Then they heard a big noise from the

street corner. They ran there and found a small car knocked(敲)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 Mrs Day's house. Ask her to call the police and the

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

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

hurt in an accident, we should not move them.

       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 trunk driver out. Luckily, the men weren't badly hurt, and the

ambulance took them to the hospital. The policemen thanked Bob and Jane, "You were very good to act

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