Yesterday when I was walking along the street, I saw an old lady in front of me.  She wanted to cross the street.  All of a sudden, a bicycle ran against her at a high speed.  The old woman fell to the ground. The cyclist was very frightened and ran away. I hurried to help the lady up, called a taxi and sent her to the nearest hospital. Luckily she was not badly hurt.
