D 跨学科 土星的新卫星(2025·连云港中考改编)
Saturn(土星) is famous for the beautiful rings around it. Now, it's getting attention for being even more amazing. Scientists have discovered 128 new moons around Saturn, bringing the planet's total to 274. A moon is any naturally formed object that moves around a planet. Moons come in different shapes and sizes.
Scientists discovered the moons with a powerful telescope(望远镜), which is used to study stars and planets in great detail. Scientists took many photos of areas in space and piled them on top of each other to make the moons appear bright enough to discover.
Most of Saturn's new moons are small objects, just one or two miles wide-quite different to Earth's Moon, which is a 2,159-mile-wide ball. These space rocks are in unusual orbits(轨道) too. They go around Saturn in the opposite direction to its own movement. At between 6.5 million and 18 million miles away from the ringed planet, the newly discovered moons are also further away than Saturn's biggest moon, Titan.
Why does Saturn have so many moons while Earth only has one? According to scientists, several billion years ago, the giant planet's gravity(重力) attracted some rocks and ice. Over time, some of them crashed against each other, breaking into smaller pieces or coming together to create many small moons.
The new moons were first discovered in 2023 by a team of scientists led by Edward Ashton, and were recently confirmed(证实) by the International Astronomical Union (IAU). Saturn now is the planet with the most moons-Jupiter is not far behind with 95. However, Dr Ashton believes this might be the limit for moon discovery. "I don't think Jupiter will ever catch up," he said. "With present technology, I don't think we can do better than what has already been done," he added.

答案
D 【文章大意】文本介绍了科学家们在土星周围发现了128颗新的卫星,使得土星成为拥有最多卫星的行星。文章还解释了土星拥有众多卫星的原因以及科学家对未来卫星发现的看法。
1.D [解析]细节理解题。根据“Scientists have discovered 128 new moons around Saturn”可知,科学家们发现了土星周围的128颗新的卫星。故选D。
2.B [解析]推理判断题。根据“At between 6.5 million and 18 million miles away from the ringed planet, the newly discovered moons are also further away than Saturn's biggest moon, Titan.”可知,这些新发现的卫星距离土星650万至1800万英里,比土星最大的卫星泰坦更远,故此处“the ringed planet”指的是土星。故选B。
3.D [解析]细节理解题。根据“... the giant planet's gravity(重力)attracted some rocks and ice. Over time, some of them crashed against each other, breaking into smaller pieces or coming together to create many small moons.”可知,土星的引力吸引了许多岩石和冰块,随着时间的推移,这些物体相互碰撞,破碎成更小的碎片,或者聚集在一起形成了许多小卫星。故选D。
4.D [解析]推理判断题。根据“With present technology, I don't think we can do better than what has already been done”可知,阿什顿博士认为,以目前的技术水平,他们已经做到了极致,不太可能再有新的发现,这表明他对团队的卫星发现感到满意。故选D。

解析
【分析】
本题是一篇关于土星新卫星发现的跨学科英语阅读理解，共4道题，包含细节理解题、单词指代推断题、推理判断题。解题思路为：先通读全文把握文章主旨（科学家发现土星128颗新卫星及相关原因、科学家看法），再针对每道题的题干关键词，回到原文定位对应信息，对比选项排除错误项，得出正确答案。
【解析】
1. 细节理解题：根据原文第一段“Scientists have discovered 128 new moons around Saturn”可知，土星周围发现了128颗新卫星。A选项“新发现的卫星外观相同”原文未提及；B选项“科学家偶然发现新卫星”与原文“用强大望远镜研究发现”不符；C选项“土星环吸引众多科学家”原文是土星因环出名，并非吸引科学家，故选D。
2. 单词指代推断题：定位到第三段“At between 6.5 million and 18 million miles away from the ringed planet, the newly discovered moons are also further away than Saturn's biggest moon, Titan”，此处提到新卫星比土星最大的卫星泰坦更远，故“the ringed planet”指代土星，选B。
3. 细节理解题：根据原文第四段“Over time, some of them crashed against each other, breaking into smaller pieces or coming together to create many small moons”可知，卫星间的碰撞导致了土星众多卫星的形成，故选D。
4. 推理判断题：根据最后一段Dr Ashton的话“With present technology, I don't think we can do better than what has already been done”，意为现有技术下已做到极致，说明他对团队的卫星发现感到满意，故选D。
