题目
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 Earth-like. But 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 colonics 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.（1）What is the best title for the text？ ____ A. A Is there life on Mars？B. Can we adapt to Mars？C. Should we terraform Mars？D. Are Mars and Earth So Different？（2）What does the author think we should do if life is found on Mars？ ____ A. Ensure that it's not harmed.B. Negotiate with the Martians.C. Change the unpopulated regions.D. Assess the advantages and disadvantages.（3）What does the underlined word "indigenous" in paragraph 3 mean？ ____ A. Complex.B. Native.C. Foreign.D. Intelligent.（4）How does the author develop his ideas in the text？ ____ A. By referring to others' research.B. By evaluating different planets.C. By justifying the benefits of terraforming.D. By arguing in support of one viewpoint.

题目解答
答案
（1）C． 标题归纳题。根据第二段"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 Earth-like. But the bigger question is， should we？不过，火星是不同的。虽然未来的基地可以随着时间的推移而适应火星的环境，但也有可能改变周围的环境，而不仅仅是与之共存。这是一个地形形成的过程--调整火星的大气和环境，使其更像地球。但更大的问题是，我们应该吗？"以及第三段"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.其中一个主要问题是火星是否有原生生命，如果有，是否应该尽可能地保存下来？如果答案是肯定的，那么火星上大规模的人类住区应该是完全禁止的。 "可知本文主要讲述了当我们继续探索更远的太阳系和更远的地方时，生活在其他星球上的人类的问题经常出现．但是调整火星的大气和环境，使其更像地球吗？所以"B．Should we terraform Mars？"作为题目最合适。故选C．
（2）A． 细节理解题。根据第三段"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 colonics might be fine， but living on Mars should not be at the expense of any native habitats， if they exist.其中一个主要问题是，火星上是否有原生生命，如果有，是否应该尽可能多地保存下来？ 如果答案是肯定的，那么火星上的大规模人类定居点应该是完全禁止的。 小型殖民地也许可以，但是如果它们存在的话，生活在火星上，不应该以牺牲任何原生栖息地为代价。"可知如果火星上有生命，作者认为我们应该确保它不会受到伤害。故选A．
（3）B．词义猜测题。根据文章第三段， Small colonics 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 anyindigenouslife，then terraforming should be a non-issue； it simply should not be done.小型殖民地也许可以，但生活在火星上不应该以牺牲任何原生栖息地为代价，如果火星是任何原生生命的家园，那么地形形成就不应该是一个问题，根本不应该这样做。可知，划线单词意为：本土的，结合选项：A．Complex复杂的；B．Native本土的；C． Foreign外国的；D．Intelligent聪明的。故选B．
（4）D．推理判断题。根据第三段"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 colonics might be fine， but living on Mars should not be at the expense of any native habitats， if they exist.其中一个主要问题是，火星上是否有原生生命，如果有，是否应该尽可能多地保存下来？ 如果答案是肯定的，那么火星上的大规模人类定居点应该是完全禁止的。小型殖民地也许可以，但是如果它们存在的话，生活在火星上，不应该以牺牲任何原生栖息地为代价。"以及根据第四段"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.如果火星是没有生命的呢？即使那里没有生命存在，也需要尽可能地保护未受影响和独特的外星环境。"可知作者是通过辩论来支持自己的观点。故选D．
