根据下面四幅图画，以“A Good Deed”为题按顺序写一篇约50字的短文。 A Good Deed Yesterday when Susan was waiting for the bus at a bus stop, she saw a purse lying on the ground. She picked it up and opened it. In it was some money and a telephone card. She wanted to find out who lost it. So she went to a public telephone and dialed the number on the card. Fortunately someone answered the phone. When the lady came and got back her purse,she thanked Susan for her good deed.
