up， with grateful smiles on their faces.
【答案】
One possible version： Paragraph 1：
Suddenly， a boy fell off the back of the bus. He hit the road face down and rolled over. He lay still in the middle of the road as the bus sped away. None of the cars behind stopped. Thinking that could die in a matter of minutes， I stopped my car and carefully examined the boy. With the help of some passers-by， I lifted the unconscious boy into the car and raced back to the hospital. After his family was contacted， and he was wheeled into emergency surgery， I drove home， exhausted but happy.
Paragraph 2：
The next day， when I went to the hospital to see the boy， all his family got up， with grateful smiles on their faces. What a feeling it was to help save the life of another person！ I spent the rest of the day in a state of the most fabulous mood I had ever experienced. Driving home that evening， I decided on my career path. Two months of placement could not do what 30 minutes' helping an accident victim had done for me. This experience taught me that at times， the decisions are made for you－and that whatever happens is always for the best.
