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.examda.

　　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.

　　We live in a large city which is like a big family. We should care for each other.
