三、实战演练
One possible version:
Hello, everybody! It's my turn to tell you something about space. As you know, the
universe is very large. There are many galaxies in the universe. For example, our galaxy has
billions of stars. The sun is one of them in the solar system. The earth goes round the sun and
the moon goes round the earth.
So far, scientists have done a lot of research on space. Especially, Chinese astronauts have
been to space many times. China has built a great space station, and now they are working there.
I am very proud of my country, so I will study hard. I hope to become an astronaut in the future.
What about you?
Thanks!
