阿波罗号登月引起全球性的对于外太空的探索热潮。以下是三位同学对于这个话题的探讨。
Barney
Anyhow, in my opinion, er…how to say, the chances that there is life on Mars are very slim．You know, er, you know the environment there is very harsh and I can't see any chances that there are beings on it．Besides, we know that 95 percent of the air there is carbon dioxide．People cannot, er, people cannot breathe there．There is no oxygen．
Gary
You said what?You said there was no oxygen, no water on Mars?Well, listen to me, Barney, you know what Mars looks like?Red!Right!It's red!And, you know why it is red?I bet you don't．I tell you it's the RUST!What makes the iron rusty?The iron and the oxygen!!Scientists find rust does exist on Mars．If there were rust, there would be oxygen!If there were oxygen, then water must exist there!
Sylvia
I do believe you, Gary．But it means nothing about our topic today!Yes, rust consists of oxygen, but, well, it is not the direct proof to support that there is life!Cause we never saw any life of them!I won't believe it unless I see with my own eyes; only then, I shall believe there is life on Mars．However, the rust is a new idea．And, to be frank, if there were no other beings in the Milk Way, or in the universe, what a great waste it would be!You know the universe is very large, larger than you can imagine．If there are only we, the human beings, there, how lonely we are!
