     One night, Mrs Riley, an elderly woman, was walking along a dark, London street. She was carrying her

handbag in one hand and a plastic carrier bag in the other. There was nobody else in the street except two

youths. They were standing in a dark shop doorway. One of them was very tall with fair hair, the other was

short and fat with a beard(胡须).

     The youths waited for a few moments, and then ran quickly and quietly towards Mrs Riley. The tall youth

held her from behind while the other youth tried to seize her handbag.

      Suddenly, Mrs Riley threw the tall youth over her shoulder. He crashed into the other youth and they both

landed on the ground. Without speaking, Mrs Riley struck both of them on the head with her handbag, and

walked calmly away.
