求翻译：我的名字叫宗涛。我是一名初中生。我有一个梦想。我希望能成为一名宇航员。因为我认为在太空里漫步非常的美妙。在太空中向地球看去，一定别有一番风味。但是我的身体素质不够好，所以我不能成为一名宇航员。所以这只是一个梦想。是什么意思？

My name is Zong Tao. I was a junior high school student. I have a dream. I hope to become an astronaut. Because I think the very wonderful stroll in space. Looked to the Earth in space, will have some flavor. But my physical fitness is not good enough, so I can't be an astronaut. So this is just a dream.
