    My friend Alice loved diving very much and she dreamed of become a professional diver one day. However, at an age of 14, she got a disease which caused her to become complete deaf. Many people thought a person was deaf would not be able to dive well and advised him to give up. But Alice had thought differently. She went to school on the morning and then spent every afternoon diving. It was really difficulty for a deaf girl to dive. Therefore, she kept practising every day. So far she has won several gold medal and is still trying hard to achieve more.
