When I was young,I wanted to be an astronaut because i thought the space was mysterious and would like to see it by myself.At that time,I collected many toll space ships and read a lot of books about space.Over time,I lost my dream as I went to school and got busier,and I started to understand that my dream is difficult to fulfill since there are only a few astronauts in the world.As time went by,i almost forgot i used to dream of being an astronaut.By the time I saw our country's first manned spacecraft Shenzhou V went to space,I felt so proud and happy.As a result,it reminds me of my astronaut dream.From then on,I start to learn knowledge of space and study hard.Now,i an still on my way to my dream.As i grow older,I may become an astronaut,if not,I won't be regret of giving up chasing dreams.
