假如你叫雷,下面的图画讲述了你和一位男孩在上周发生的事情.书面表达

When I arrived at the school gate, I found a boy lying on the ground, with a bicycle beside him. The wheels were still rolling. It seemed that the driver had just ran away. I called the police at once, and send him to the hospital. Fortunately, he didn't injure severely. I bought a bunch of flowers and looked after him from time to time. The boy finally recovered. He thanked me a lot and we became good friends. Helping others brings happiness, doesn't it?
