Many countries are investing in space programs. Why is space exploration so important? First, it helps us understand the universe. By studying other planets, stars, and galaxies, we learn more about how the universe works. This knowledge can help us understand the origins of life and the future of our planet. Second, space exploration leads to new technologies. Many inventions we use today, such as GPS, satellite communication, and weather forecasting, were developed because of space research. These technologies have greatly improved our lives. Third, space exploration inspires people. It encourages young people to study science, technology, engineering, and math. Many astronauts and scientists were inspired by space missions when they were children. Finally, space exploration may be necessary for the survival of the human race. As the Earth’s population grows and resources become limited, we may need to find new resources or even a new planet to live on. 20．How does space exploration help us understand the universe? A．By sending people to the moon. B．By studying other planets, stars, and galaxies. C．By building more telescopes. D．By launching satellites. 21．What are some technologies that were developed because of space research? A．GPS and satellite communication. B．Computers and smartphones. C．Cars and airplanes. D．Trains and ships. 22．Why does space exploration inspire young people? A．Because they can become astronauts. B．Because it encourages them to study science and technology. C．Because they can travel to space. D．Because it is exciting. 23．What might be necessary for the survival of the human race? A．Building more cities. B．Finding new resources or a new planet. C．Stopping space exploration. D．Using more technology. 24．What is the main idea of this passage? A．Space exploration is too expensive and should be stopped. B．Space exploration has many important benefits for humanity. C．Space exploration is only about sending people to the moon. D．Space exploration is not important for our daily lives. 一、阅读理解 （2025江苏连云港中考） 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 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 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. 25．What do we know about the new discovery? A．Newly found moons look the same. B．Scientists found new moons by accident. C．Saturn’s rings attract many scientists. D．128 new moons were found around Saturn. 26．What does “the ringed planet” in Paragraph 3 refer to? A．Earth. B．Saturn. C．Moon. D．Titan. 27．What led to the large number of Saturn’s moons? A．The size of the planet. B．The weights of the moons. C．The orbit of the planet. D．The crashes of the moons. 28．What can we learn from Dr Ashton’s words in the last paragraph? A．Jupiter will soon catch up with Saturn. B．Saturn’s new moons might support life. C．The IAU presented a medal to his team. D．He is satisfied with their moon discovery. $Unit 6 Beyond Earth 课时3 Section A (3a-3c) 分层作业 A组 巩固过关 C组 思维拔高 B组 能力进阶 拓展 链接中考 ( 词汇 geology /dʒi'plədʒi/n. 地质；地质学 satellite /'sætɔlart/n. 人 造卫星；卫星 crazy /' krerzi/adj. 疯狂的；不理智的 human being 人；人类 句型 First, to improve our knowledge of Earth and its place in the universe. 首先，增进我们对地球以及它在宇宙中所处位置的认知。 The study of other planets helps us better understand Earth’s geology, history, and relationship with other planets. 对其他行星的研究有助于我们更好地了解地球的地质状况、发展历史以及它和其他行星之间的联系。 In that case , a new home for us human beings will be needed. 如果那样的话，人类将会需要一个新的家园。 ) 一、单词默写。 ( 1 / 6 ) 学科网（北京）股份有限公司 1.___________ n. 地质；地质学 2.___________ n. 人造卫星；卫星 3.___________ adj. 疯狂的；不理智的 4.___________ 人；人类 【答案】geology; satellite; crazy; human being 二、词组默写。 1. 1. 探索太空 _______________________ 2. 在宇宙中 _______________________ 3. 人造卫星 _______________________ 4. 气候变化 _______________________ 5. 外层空间 _______________________ 6. 耗尽资源 _______________________ 7. 人类 _______________________ 8. 找到新家园 _______________________ 【答案】explore space; in the universe; man-made satellite; climate change; outer space; run out of resources; human beings; find a new home 三、根据要求完成句子 1. 增进人类对地球以及它在宇宙中位置的认知十分重要。 It is important ________ ________ our knowledge of Earth and its place in the universe. 2. 太空研发的技术能够造福地球上的人们，这极具价值。 It is valuable ________ space technology ________ people living on Earth. 3. 人造卫星助力应对气候变化带来的难题，这十分实用。 It is useful ________ satellites ________ us solve climate change problems. 4. 未来在外太空寻找新型资源充满希望。 It is hopeful ________ ________ new resources in outer space in the future. 5. 人类未来或许需要一处新家园，这件事听起来有些大胆。 It is surprising ________ human beings ________ a new home someday. 【答案】 to improve that; benefits that; help to find that; will need 一、用方框内所给词的适当形式填空。 geology satellite crazy human being 1.

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。 28．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Dr Ashton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，这表明他对团队的发现感到满意。故选D。 $
