II. Space Travel
If you look at the title “Space Travel”, you must think that I am talking about real space travel. But here I am really telling you about a very good show that you shouldn’t miss, “the Space Travel Theme Park”.
Yesterday was a rainy day and my mother and I went to the Space Travel Theme Park in Haidian Exhibition Hall.
The Entrance Hall is very big. I looked upwards and saw a blue ceiling dotted with stars. I was starting to feel that I was traveling in space!
Suddenly, a statue of an ancient caught my eyes. Its eyes fixed unblinkingly on the far sky. He is Wan Hu, the man who was regarded by the whole world as ” the first man who wanted to fly up to the space”.
There is a story behind his stare. When he was looking up to the blue sky, a dream created in his mind－ If I could fly into the sky…
I watched Wan Hu for a long time, how important the dream is! I believe most of today’s accomplishments started as a dream, perhaps a silly dream. How I admire Wan Hu!
“Come on, dear! Three scientists are waiting for you!” my mum called. I hurried over. “I know them, they are Newton, K﹒E﹒Tsiolkovsky and Verne﹒Jules.” I said eagerly. “Yes, they had made lot of great researches for the space science.”
Suddenly, an idea came into my mind －a dream is not enough. A scientific method is very important, too!
Then, a big model of a space shuttle came into view. It is the well-known Columbia. My mother and I climbed into the space shuttle quickly. There were so many keys here and there. I was so amazed and enchanted at the sight. What a complex space shuttle!
And then, my attention was caught at once by the portraits hang on the wall. The people in the portraits were seven famous astronauts! They all dedicated their dear lives to Columbia space flight.
I realized that if a person only has a dream and scientific method, it is still not enough. They must have outstanding courage and selfless devotion.
“It is really valuable and really interesting.” My mother said to me when we left the hall. I nodded whole-heartedly.
The rain continued heavily. The show of space travel is more than an adventure. I have really learned how a dream comes true－have a dream, love science, and then be dedicated to it! I will remember this for all my life.
