Mike is happy because he can ride his e- bike well. But he doesn't like 1 a helmet (头盔) when he rides it. His mum tells him that it is 2 , but he doesn't listen to her.
Last Sunday morning, his dad had a cold (感冒), so Mike went to buy some 3 for him by e- bike. On the way he saw some people on the side of the road. Mike stopped and wanted to find out 4 was going on. As he came closer, he saw a woman lying on the ground. Her face looked 5 and she was putting her head in her hands. "She was talking on the phone and didn't 6 the road cleaner. She stopped in time but fell off her e- bike. 7 , the cleaner didn't hurt," a young woman told Mike.
"Look, Dad! There is much 8 on her face," a girl shouted. "But we can't move her. We have to wait till an ambulance (救护车) 9 ," her dad said. Minutes later, the ambulance came. A doctor first moved the woman's arms and legs slowly, then looked 10 her head. "There is 11 serious with her legs and arms, but her head seems to hurt badly. Let's move her into the ambulance," the 12 said.
Then Mike heard a voice. "Don't listen to music or make phone calls 13 riding and driving! And remember to wear a helmet when riding a bike. It can help cut down the 14 of accidents," said a policeman.
Mike learnt a lesson from the 15 ! "I will wear my helm et from now on," he said to himself.
