Tony：Sure，no problem. Have you heard the latest news? Scientists have sent a spaceship to Mars. The journey has taken several months．

托尼：当然可以，没问题。你听说最新的新闻了吗？科学家已经向火星发射了一艘宇宙飞船。它在太空中已经行驶了好几个月了。

Daming:Has it arrived yet?

大明：它已经到达了吗？

托尼：没有。

Daming: Why not? Astronauts have already been lo the moon．

大明：为什么没有？宇航员已经去过月球了。

Tony:Yes，but no one has been to Mars yet，because Mars is very far away，much farther than the moon．Lots of scientists are working hard in order to send astronauts to Mars one day．

托尼：是的，但是还没有人去过火星，因为火星很遥远，比月球远多了。很多科学家正努力工作，为了有一天把宇航员送到火星上去。
