　　It was last July 21st. It rained so hard in Beijing that some villages were watered by the flood. At about 1:00 o’clock, Li Fanghong, the police officer of our district, went to see the villagers. When he saw rainwater coming into one of the houses, he organized them to leave to safety. However, while he was carrying an old man, he was killed by electricity.
　　
　　I was deeply moved by his story. I think he is not only a good officer but also a brave hero of us. He did his best when he faced great danger. I should learn from him. I will think of others first and help them as much as possible when facing difficulties.
