我们应该把火星“地球化”吗？

山东新泰第一中学 仲 宁

当我们继续探索太阳系及更远的地方时， 人类在其他星球上能否生活的问题也随之出现。 人类是否应该移民火星？ 如果人类在火星上大规模建造定居点，这有可能进一步改变火星周围的环境使之更适合人类居住。As we continue to explore farther out into our solar system and beyond, the question of humans living on other planets often comes up. Manned bases on the Moon or Mars for example, have long been a dream of many. There is a natural desire to explore as far as we can go, and also to extend humanity's presence on a permanent or at least semi-permanent basis. In order to do this, however, it is necessary to adapt to different extreme environments. On the Moon for example, a colony must be self-sustaining and protect its inhabitants from the airless,harsh environment outside.

Mars, though, is different. While future bases could adapt to the Martian environment over time, there is also the possibility of modifying the surrounding environment instead of just co-existing with it. This is the process of terraforming—adjusting Mars' atmosphere and environment to make it more Earthlike. Although still a long way off technologically, terraforming the Red Planet is seen as a future possibility. Perhaps the bigger question is, should we?

One of the main issues is whether Mars has any native life or not and if it does, should it be preserved as much as possible? If the answer is yes, then large-scale human settlements on Mars should be completely off-limits. Small colonies might be fine, but living on Mars should not be at the expense of any native habitats, if they exist. If Mars is home to any indigenous life, then terraforming should be a non-issue; it simply should not be done.

What if Mars is lifeless? Even if no life exists there, that untouched and unique alien environment needs to be preserved as it is as much as possible. We've already done too much damage here on our own planet. By studying Mars and other planets and moons in their current natural state, we can learn so much about their history and also learn more about our own world. We should appreciate the differences of other worlds instead of just transforming them to suit our own ambitions.

【翻译】_____________________________________________________________________________

【点石成金】这是一个并列句，whether Mars has any native life or not是从属连词whether引导的表语从句，whether引导表语从句时含有“是否”之意，起到引导作用，不充当从句的任何成分，不能省略。if it does是连词if引导的条件状语从句，谓语动词does是省略用法，相当于has any native life。
