According to the passage, the chief purpose of explorers in going to unknown places in the past was______. [br] What is the main goal of sending human missions to Mars?
选项
A、To find out if life ever existed there.
B、To see if humans could survive there.
C、To prove the feasibility of large-scale space ventures.
D、To show the leading role of science in space exploration.
答案
A
解析
综合判断题。本题问及人类登上火星的主要目标是什么。C、D容易排除。那么到底是为了发现火星上是否存在生命还是看看人类是否能够在火星上生存呢?文章最后一段讲,因为越来越多的证据证明,火星上是否曾经存在过生命并且是否持续到现在这个问题已经变得很突出了。对火星是否存在生命做出一个更确凿的令人信服的回答,会给研究者们提供宝贵的产生生命条件的数据。如果可以确定生命在火星和地球上是分别独立产生的,就会进一步解开“生命在宇宙中是否普遍存在”这个谜。综上所述,人类登上火星的主要目标是为了发现火星上是否存在生命。所以选A。
