A Lecture on Space Flight(一次航天飞行讲座) A Lecture on Space Flight Last Saturday I attended a lecture on space flight. I am glad that I have learned a lot about space. Now I know something about the structure of a space rocket and understand the importance of space flight to mankind. I become interested in space. Yesterday I borrowed several books on space from the school library. I want to be a space scientist in the future. |
