I have a dream that (one day) I can be an astronaut.
Although our earth is very big(large),but there are sixty-five hundred millions people in the world.One day the resource will (be used up).It’s terrible!I want to be an astronaut because I want to find a new star for people to start their new life.In spite of having difficulties,I still believe my dream will come true.For example,I must have (a)strong and healthy body and analytical ability.(Despite) I am a girl,but I will work hard for my dream.
