Two years ago, my father asked me if I wanted to be a doctor when I grew up. I said No at once because I didn’t like this job at all. But now, I change my mind. A month ago I went to see the doctor. I found that many doctors weren’t careful enough to look over the patients. They liked to give the patients the most expensive medicine. I was very angry. So I make up my mind to be a doctor in the future. Doing this is very rewarding because it can help save people’s lives and make people healthy. My grandma died of cancer. I want to heal people who have cancer. Now we have no ideas and no good medicine to heal those people. Cancer makes many people lose their lives, makes their relatives cry hard and spends much money. So I will work hard from now on. I wish I could work out this difficult problem with other friends.
