求英语作文：I want be an astronaut

I want to be an astronaut
When I was young,I always wondered what were in the sky.I wished that one day I could fly into space to find the secrets of the universe.Now I am more interested in space.Yang Liwei bacme the first Chinese astronaut to get into space and Zhai Zhigang became the first Chinese to walk in space.All the Chinese people are very proud of them and so am I.I also want to be an astronaut,so I study so hard that my dream can come true one day.
If i become an astronaut,I will work hard and learn from others.I will try my best to make a contribution to exploring other planets and finding new places for human living.I'm sure all the Chinese will be proud of me in the future,too.
