D(真题·温州)
Are we alone in the universe? How can we know if there is life out there in space? Just as the famous scientist Carl Sagan said, “Where there's water, there might be life.” We've searched for water on many other planets, especially on Mars.
In 1877, Schiaparelli watched Mars and noticed some lines. Some people believed the lines could be man-made rivers and life on Mars built them. Then, in 1964, NASA sent Mariner 4 to take photos of Mars. Yet there was nothing to see on the planet, just a cold and dry wasteland.
This didn't stop people's interest. Scientists decided to find out if there was once life on Mars. In 2004, NASA's two rovers(探测器), Spirit and Opportunity, found white lines on rocks from different places on Mars. It showed that perhaps water moved through the ground before. In 2013, another rover, Curiosity, found 2% of water in the soil(土壤) on Mars.
The discoveries were encouraging. However, they were still not enough to show there was life on Mars. These days a Chinese research team opened new doors. After China's Zhurong rover reached Mars on May 22nd, 2021, the team studied the area around the rover's landing place. They found special layers(层) of rocks. The layers looked a lot like those near the earth's coastlines. This finding has been the biggest so far. It shows there was a sea on Mars a long time ago!
The discovery makes people believe that Mars was once warm, wet and habitable. To make Mars a good place to live again, scientists can study how it changed from warm and wet to cold and dry. Now, China is planning to send astronauts to Mars. We are the ones who will go on writing the history. Was there life on Mars? What surprising facts will be discovered next? Let's wait and see!

27.D 28.C 29.A 30.B
本文是一篇说明文,围绕“火星是否存在生命”展开,介绍了人类对火星的探索历程(从早期观测到现代探测器发现),重点阐述了火星上的水相关证据,以及中国祝融号探测器的新发现(火星曾存在海洋),体现了对火星生命可能性的持续探索。 第27题:考查类型:细节理解题(写作手法判断)。解析:根据第1段“Just as the famous scientist Carl Sagan said, ‘Where there's water, there might be life’”,可知作者通过引用著名科学家的话,来体现水对寻找生命的重要性。D选项“他使用了名人的言论”符合原文。故答案为D。 第28题:考查类型:细节排序题(事件时间线梳理)。解析:1877年:“Some people believed the lines could be man-made rivers”(对应③);2004年:“perhaps water moved through the ground before”(对应④);2013年:“found 2% of water in the soil”(对应②);2021年:“there was a sea on Mars a long time ago”(对应①);正确顺序为③④②①,对应C选项。 第29题:考查类型:词义猜测题(语境语义推断)。解析:根据第5段“Mars was once warm, wet and habitable”及后文“To make Mars a good place to live again”,可知“habitable”与“a good place to live”对应,意为“适合居住的”。A选项“Fine to live on”符合语义。 第30题:考查类型:主旨大意题(最佳标题选择)。解析:文章核心围绕“火星是否存在生命”展开(从水的证据到环境的推测),B选项“Hello, Is Anyone on Mars?”(你好,火星上有人吗?)既呼应了“寻找火星生命”的主题,又带有探索的趣味性,契合文章核心。故答案为B。 

【分析】
27题：定位第一段，作者通过引用著名科学家Carl Sagan的话来体现水对寻找生命的重要性，据此判断选项。
28题：需梳理火星发现的时间线，按文中提及的各发现的时间先后排序，匹配选项。
29题：结合第五段“warm, wet”的语境，推测划线词含义，对应合适选项。
30题：通读全文，把握核心主题（火星是否存在生命），选择最贴合主旨的标题。
【解析】
27题：第一段中作者引用著名科学家Carl Sagan的名言“Where there's water, there might be life.”来表明水对寻找生命的重要性，因此选D。
28题：按时间顺序梳理发现：1877年认为火星有人造河流（③）；2004年发现火星曾有水流过地面（④）；2013年发现火星土壤中有水（②）；后续发现火星曾有海（①），正确顺序为③④②①，选C。
29题：第五段提到火星曾“warm, wet”，结合语境，“habitable”意为“适合居住的”，对应选项A。
30题：全文围绕“火星是否存在生命”展开，B选项“Hello, Is Anyone on Mars?”贴合主题，选B。
【答案】
27.D 28.C 29.A 30.B
