If I were an astronaut on Shenzhou VIII, I would write a composition.

If I were an astronaut.

My dream is to be an astronaut. Because I saw three astronauts of Shenzhou VII go to space to explore the mystery in 2008, I also want to go to space to explore the mystery.

If I were an astronaut, I would go to space to see what the universe looks like and how big it is.

If I were an astronaut, I would go to Mars to see if there is life on it.

If I were an astronaut, I would go for a walk in the moonlight sky and try to see if it is difficult to walk in the moonlight sky. If I walk too fast, it is easy to fly.

If I were an astronaut, I would go to the moon to see if there were Chang 'e and Yutu on the moon.

If I were an astronaut, I would go to Jupiter to see if Jupiter would become another sun in 3 billion years.

If I were an astronaut, I would go to the universe to see if the stars would collide and how far apart they were.

If I were an astronaut, I would take Shenzhou VIII to explore many mysteries in the universe.

If I am an excellent astronaut, I will take my parents and grandparents to live in the universe and open their eyes. The universe is a beautiful place.

Now I am just a student, but I must realize my dream and become an excellent astronaut when I grow up. Explore many mysteries in the universe.
