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!

解析
【分析】
本题为英语阅读理解题，需根据原文内容逐一分析各题：
1. 第27题：定位第一段，查找作者展示水对寻找生命重要性的论证方法；
2. 第28题：梳理文中关于火星发现的时间线，按时间先后匹配对应内容；
3. 第29题：结合第五段语境，推测划线词“habitable”的含义；
4. 第30题：概括全文核心主旨，选择最贴合的标题。
【解析】
27题：定位原文第一段，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：按文中时间顺序梳理发现：1877年人们认为火星有人造河（③）；2004年探测器发现岩石显示水曾流过地下（④）；2013年好奇号发现土壤含2%的水（②）；2021年祝融号发现火星曾有海（①），顺序为③④②①，选C。
29题：第五段提到火星曾温暖潮湿，后文提及“让火星再次成为宜居之地”，结合语境可知“habitable”意为“适合居住的”，对应A选项。
30题：全文围绕“火星上是否存在生命”展开，讲述人类对火星的探索发现，B选项“Hello, Is Anyone on Mars?”最贴合主旨，故选B。
【答案】
