When I was a little girl,my grandmother used to tell me stories about the moon.Even today,every time I watch the sky at night,I would imagine what is happening among the twinkling stars.I hope to be an astronaut in the future so that I can walk in space.I want to walk on the Mars and meet living creatures there.I know it's not easy to be an astronaut.So I study hard and try to learn more about space in order to be a good astronaut.
