Question

The question whether there is life on Mars (火星) has made the public think a lot for more than a century. The closest look showed Mars to be a dusty, cold world, covered by air too thin to breathe. A British spaceship and Europe's Mars spaceship plan to land on Mars or enter orbit (轨道) around it. One of the NASA’s (美国宇航局) spaceships is expected to land on January 3, the other is going to land on the opposite side of Mars on January 24. Since 1960, over twenty spaceships sent to Mars have failed. Most have been lost on flying up or landing because those are the most difficult times of any flights.     Scientists wanted to find out whether there was water in Mars. In October, a team of scientists reported that Mars had been a dry wasteland. But weeks later, a second team reported differently that they had found some marks showed clearly that they were made by the rivers. Such marks told us that Mars was a warmer place billions of years ago — just as life first appeared here on Earth. Scientists at once raise a question: if what they said is true, what happened on Mars? Then what about the earth?

解析试题分析：一个多世纪火星上是否有生命的问题让公众想了很多。最接近的发现表明，火星是一个尘土飞扬的，寒冷的世界，覆盖太薄的空气。一英国飞船和欧洲的火星飞船计划降落在火星或进入它周围的轨道。美国航空航天局的太空飞船，预计1月3日土地，另一种是在1月24日降落在火星的另一侧。自1960年以来，超过20飞船送往火星，都失败了。大部分已遗失或着陆飞不起来了。科学家们想找出在火星上是否有水。 10月，研究小组的科学家报告说，火星一直干荒地。但几周后，第二小组的报告，他们发现了一些痕迹清楚地表明，。这类标记告诉我们，火星数十亿年前一个温暖的地方，科学家们立刻提出了一个问题：如果他们说的是真实的，在火星上发生了什么事？那地球呢？
