【答案解析】February 12th, 2008 The day is my Dad's birthday. This afternoon I went to the shopping center downtown, and bought a present for him. Then I took the subway train home. Sitting on the train, I thought my Dad would be very happy when he saw the present. At the next station, an old lady with two heavy bags got on the train and stood in front of me. She looked tired. I hesitated for a moment, and then offered my seat to her. The old lady thanked me a lot and sat down. Seeing her smile, I felt happy. I will always be ready to help others in the future.
