【正文】 be a doctor is because of one thing: when I came home from a holiday, my mother told me that my sister was ill in hospital. At that time, I was very worried, so I quickly went to the hospital to see my sister. When I got to the hospital, I entered the ward and saw my sister. I saw my sister wearing an oxygen mask and sleeping with her eyes closed. My mother said to me, “my sister’s illness is not very serious, but her resistance is still poor. She has a fever and a cold...” when I saw my sister so unfortable, I thought that others were worse than her, so I had a thought in my heart I want to be a doctor.　　Being a doctor can not only heal the pain of family members, but also save the lives and heal the wounded, treat other patients and let them return to their usual health.　　Now that I have made clear the goal of being a doctor, I tell myself that I must plete this dream. From now on, I will strive for the goal of being a doctor! I want to pursue unremittingly!　　First of all, I want to study hard and listen to the teacher that it is not easy to be a doctor, so I want to work harder.

When I came home from school, as soon as I finished my homework, I couldn’t wait to turn on the DVD player, put on beautiful music, and involuntarily sang along with it. The happiness was indescribable.　　I think I have a talent for music since I was a child. In the fourth and fifth grades of primary school, the class held a little singer petition. I always came first. Now I am in the sixth grade. Every Sunday, I will check the Internet for good pop songs, and then learn slowly and try to imitate the voice of singers. I am pletely immersed in the world of music. In this way, I became a famous little singer in my class.　　One day, I watched Zheng Zhihua’s concert on TV. He sang on crutches. I was particularly moved. I think his life is very unfortunate: he suffered from paralysis at the age of three. At the age of six, his legs couldn’t bend straight. At the age of seven, he went to the hospital and straightened himself. Finally, he only walked on crutches. One of his most famous songs is sailor. After watching his concert, I think he succeeded through hard work, strength and courage. Yeah! How can you see a rainbow without going through wind and rain?
