　　_________________________________________________ 答案： I witnessed a moving scene with my own eyes at the railway station on National Day last year. At that time，a woman was sorting out her luggage when a tall man suddenly ran ahead of her and tore off her handbag，fleeing away. The woman was scared to death，so it took her a long time to be aware of what had happened. Unfortunately，the people around her didn't give her a hand because they were terrified of getting into trouble. To my relief，in the distance I saw a young man fighting with the tall man, who was finally caught with the help of the other people，which made me realize that it is very important to help others out when they are in need.
