For more than a century, people have wondered whether there is life on Mars. Scientific searches for
this began in the 19th century, and they 1 today with the development of research methods and
space science.
In the late 19th century, the American scientist Percival Lowell thought he saw rivers on the surface
of Mars, and if this was true, it might 2 that our near planetary neighbour might have life on it.
However, in the 1960s and 70s, the spaceship sent to Mars found that the rivers did not exist. Instead,
they showed a cold 3 world. Even so, people were quite excited to watch the first pictures sent from
the 4 of this mysterious planet by spacecraft.
Is it possible that there is life on Mars?
5 no one can make sure, it is not completely impossible.
To have life, there needs to be fresh water. Evidence for that has been growing and NASA seemed to
have found that there was a little water there in 6 research. In 2000, NASA discovered gullies (冲沟) that might have been 7 by running water. But the temperatures were so low that water would turn
into ice, so many gave up the idea.
For now, the latest 8 reported earlier has found different kinds of salts on the crater walls (火山
口壁). That’s important because salt can melt (融化) ice and make it flow. The 9 proves that Mars
is still active and it 10 the possibility that it may have simple living creatures.
We can look forward to having closer contact with unknown friends away on Mars in the future.

先通读下面的短文，掌握其大意，然后在每小题所给的四个选项中，选出可以填入空白处的最佳选项。
一个多世纪以来，人们一直想知道火星上是否有生命。对火星生命的科学探索始于19世纪，并且随着研究方法和空间科学的发展，这种探索一直持续（D）到今天。
19世纪末，美国科学家珀西瓦尔·洛厄尔认为他看到了火星表面的河流，如果这是真的，那就可能证明（C）我们的近邻行星（火星）上可能有生命。
然而，在20世纪60年代和70年代，送往火星的宇宙飞船发现那些河流并不存在。相反，它们展现出的是一个寒冷、荒芜（C）的世界。即便如此，人们还是很兴奋地通过宇宙飞船看到了从这颗神秘星球表面（A）发回的第一批照片。
火星上有可能存在生命吗？
尽管（D）没有人能确定，但这也不是完全不可能的。
要存在生命，就需要有淡水。有关火星存在淡水的证据越来越多，美国国家航空航天局（NASA）在早期（C）的研究中似乎发现火星上有少量的水。2000年，NASA发现了可能是由流动的水造成（B）的冲沟。但火星的温度太低了，水会变成冰，所以很多人放弃了（火星存在生命的）这个想法。
目前，早些时候报道的最新研究（D）在火山口壁上发现了不同种类的盐。这很重要，因为盐可以融化冰并使冰流动。这一发现（B）证明火星仍然是活跃的，并且这增加（C）了火星上可能有简单生物的可能性。
我们可以期待未来能与火星上未知的“朋友”有更密切的接触。
