Ⅴ.阅读理解
A
(2020·广州毕业班二测)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 self­sustaining 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 coexisting with it.This is the process of terraforming—adjusting Mars' atmosphere and environment to make it more Earth­like.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 large­scale human settleme
nt on Mars should be completely off­limits.Small colonies might be fine，but living on Mars should not be at the expense of any native inhabitants，if they exist.If Mars is home to any indigenous life，then terraforming should be a non­issue；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.
[语篇类型]　议论文
[主题语境]　人与自然——宇宙探索——我们是否应该将火星地球化
[语篇解读]　移居到地球以外的星球一直是人类探索的方向。如果我们移居到火星上就有可能将火星地球化。但是考虑到火星上有原始生命或者即使无生命也应保持其原状以便我们了解到更多东西，我们不应该将火星地球化。
1．What is the best title for the text?
A．Is There Life on Mars?
B．Can We Adapt to Mars?
C．Should We Terraform Mars?
D．Are Mars and Earth So Different?
解析：标题归纳题。通读全文可知，本文是围绕第二段尾句“But the bigger question is，should we？”提出的问题展开议论的，又结合下文论述的不应该以牺牲火星上的原始生命为代价而去改变火星上的环境以适应人类的生存，以及即使火星上无生命我们也应让它保持原状以便我们了解到更多东西可知，C项最适合作本文标题。
答案：C
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.
解析：细节理解题。根据第三段中的“large­scale human settlement on Mars should be completely off­limits”“living on Mars should not be at the expense of any native inhabitants，if they exist”“it simply should not be done”可知，如果火星上有生命存在，我们应当避免大规模移民，应当尽力保护其不受伤害，故A项正确。
