thin atmosphere 稀薄的大气
Scientists have previously found signs of ice on the Moon and water vapour in its thin atmosphere.科学家们此前已经在月球上发现了冰存在的迹象，也在月球稀薄的大气中发现了水蒸气存在的迹象。
But this, they say, is unambiguous evidence of H2O on its surface. And there appears to be more of it than previously thought.但科学家们表示，这个发现是月球表面存在水分子的确凿证据。而且水分子的含量似乎比以前所设想的还要多。

1.Do you want to travel in the outer space?
You bet! I doubt there exists a human being who wouldn’t jump to seize the chance if they can set out on a space travel, of course provided it is totally safe.
2.What would you do if you had that opportunity?
I’d like to be the first one who ever set foot on the Mars and I want to check it out whether there is water or life with my naked eyes.
3.Do you think it's necessary to see other planets?
I don’t know. I mean on the one side the mankind is an adventurous race that should not be bound by earth or solar systems, but on the other side, many si-fis and even some renowned scientists warn of the potential unexpected consequences if we are set to space exploration.
4.When was the last time you went travelling?
I am not a travel bug that will do all kinds travelling even in the weekends. So maybe it is no or all for me , and the last time I traveled I went across half of the world to the far away north Africa, Morocco with my dear wife. It’s August 2017 and it’s my honeymoon travelling.
5.Do you like to travel by air?
Not really, since I don’t feel comfortable in the rather cramped economy seat which is what I can afford, and the long wait for departure is tiring. So basically the whole experience is worse than that of a train travel in China.
