(B)
Many of us have watched science fiction films about aliens. In these films,
people travel to other planets and even fight against alien beings. But do aliens really
exist in the universe? Most people think it's unlikely, but some scientists say "yes".
For years, they have been seeking out aliens in outer space, hoping to find signs of
alien life.
Some scientists use radio telescopes to look for aliens in space.
To find them, they have worked hard for more than 50 years, but so far, they haven't
found any useful signs. Then some scientists guessed that aliens might be able to reply
to our messages, but they do not want to contact us. So these scientists sent radio
signals into the universe. They hope that one day, alien will pick up these signals.
Their goal is to prove that we are not alone in the universe.
But what if the "alien phone" rings one day? Should we answer it? Stephen
Hawking, the famous physicist, thought that contacting aliens could bring disasters.
He said the main reason aliens might visit the Earth could be to search for our
resources. However, other scientists believe we don't need to worry. A leading space
scientist explained, "If an alien radio signal reaches the Earth from a planet thousands
of light-years away, they almost certainly have solved all the problems we still face—
including resource shortages. They are probably much smarter than us, so why would
they want to hurt us? I think we can try to contact them. "

解析
【分析】
本篇是关于外星人话题的阅读理解题，解题思路如下：
1. 词义猜测题（第46题）：需结合划线短语所在句的上下文，根据“hoping to find signs of alien life”（希望找到外星生命迹象）可推断短语含义；
2. 细节理解题（第47、48题）：需定位原文对应句子，找到题干问题的直接表述；
3. 推理判断题（第49题）：需分析最后一段中不同科学家的观点，总结段落核心；
4. 主旨大意题（第50题）：需梳理全文围绕的核心话题，提炼文章标题。
【解析】
46. 定位第一段划线短语所在句：“they have been seeking out aliens in outer space, hoping to find signs of alien life”，其中“hoping to find”（希望找到）对应“searching for”（寻找），故“seeking out”意为“寻找”，选B。
47. 定位第二段：“some scientists guessed that aliens might be able to reply to our messages, but they do not want to contact us”，说明科学家未找到外星人是因为外星人可能拒绝联系，选D。
48. 定位第三段：“Stephen Hawking... thought that contacting aliens could bring disasters”，“disasters”对应“dangerous”（危险的），选B。
49. 最后一段提到霍金认为联系外星人会带来灾难，另一位科学家认为可以尝试联系，说明人们对联系外星人有不同观点，选D。
50. 全文围绕“是否应该联系外星人”展开讨论，核心话题是这个问题，故最佳标题为“Should We Contact Aliens”，选C。
