China’s Chang’e-7 mission,scheduled for launch in mid-2026,will undertake the most comprehensive survey of the lunar south pole so far.Its tasks include high-precision topographic mapping,detection of water ice and mineral resources,and environmental monitoring for future station construction.The probe carries a landing device,a rover,and a mini-flying detector that can enter narrow craters unreachable by traditional machines.These tools will work together to record data in temperatures as low as-240℃,nearly the coldest point in the solar system. What makes Chang’e-7 different from earlier missions is its international vision.The project accepts cooperation from scientists worldwide,sharing data and technological achievements openly.This spirit matches the global appeal that lunar exploration should serve all humanity,not just single nations.At the same time,NASA’s Artemis program and Europe’s lunar projects are also targeting similar regions,creating a wave of peaceful competition and cooperation. However,stepping into the unknown never comes without risks.Solar storms,communication delays,unstable terrain,and equipment failure could threaten the mission at any moment.Scientists must balance courage with strict risk control,reminding the world that true exploration is not just about discovery,but about wisdom,responsibility,and long-term thinking. 21.What is the main task of Chang’e-7? A.Bring back large quantities of soil samples immediately. B.Survey the lunar south pole and prepare for the research station. C.Complete China’s first manned lunar landing. D.Replace all artificial satellites around the moon. 22.What makes the lunar south pole extremely challenging? A.Permanent darkness and extremely low temperature. B.Frequent human activities and crowded landing sites. C.Strong magnetic field and serious radiation. D.Unstable Internet supply and limited energy. 23.What can we infer from the passage? A.Lunar exploration has become a global joint effort. B.All lunar missions can achieve goals safely. C.Water ice is already widely used on the moon. D.The moon’s environment is similar to Earth’s. B In 2025,China’s deep-sea manned submersibles completed a record number of dives,pushing the nation’s ocean exploration into a new historical stage.Among the three major submersibles—Jiaolong,Shenhai Yongshi,and Fendouzhe(Striver)—the latter achieved the most groundbreaking progress by carrying out the first manned dive in the Arctic dense ice zone.This mission was supported by Tansuo-3,the world’s first professional ice-breaking research mother ship,creating a new model for polar deep-sea exploration. The Arctic expedition was far more difficult than any ordinary dive.Thick floating ice constantly hit the ship and submersible,while temperatures below-30℃threatened to freeze equipment and pipes within minutes.Visibility was near zero under the ice,and underwater currents were strong and unpredictable.Even with modern technology,every dive required hours of careful planning and real-time monitoring to avoid disasters. During the mission,the team collected thousands of biological,mineral,and water samples,many of which came from depths never before reached by humans.Scientists discovered several new species that survive completely without sunlight,feeding on chemical energy from the Earth’s interior.These findings challenge traditional beliefs about the limits of life and provide new ideas for research on climate change and ecosystem evolution. Before this exploration,many people considered the deep ocean and polar regions as silent,lifeless worlds.However,recent data shows that these areas are highly active,with complex food chains and unique environmental systems.They are not only key to understanding Earth’s history but also potential sources of new energy and biological resources. In 2026,more missions will enter the Arctic and Antarctic deep seas.As technology improves,more unknown regions will become accessible.Humans are gradually realizing that ocean exploration is not a luxury,but a necessity for sustainable development.The deep sea remains the largest unknown space on Earth,and it is calling for brave and wise explorers. 24.What made Fendouzhe’s 2025 Arctic mission special? A.It reached the deepest point of the Mariana Trench. B.It was China’s first manned dive in the Arctic dense ice zone. C.It used fully imported technology and equipment. D.It only focused on underwater ancient relics. 25.Which of the following challenges did the team NOT face? A.Thick and moving floating ice. B.Extremely low temperature. C.Risk of equipment freezing. D.Attacks from large sea animals. 26.What is the value of the new deep-sea findings? A.They prove all former biological theories correct. B.They help study life limits and climate change. C.They make tourist diving safe in polar areas. D.They reduce public attention to ocean protection. 27.What is the main idea of the passage? A.China’s deep-sea exploration reaches a new international level. B.Manned submersibles are too expensive to develop. C.The Arctic is easier to explore than the Pacific Ocean. D.All deep-sea mysteries will be solved soon. C The combination of deep-sea engineering and archaeology has created a new wave of discoveries in the South China Sea.In 2025,archaeologists using advanced submersibles found two well-preserved ancient shipwrecks from the Ming Dynasty,located at a depth of more than 1,500 meters.These wrecks,covered with gold,porcelain,and wooden structures,provide priceless evidence of ancient maritime trade routes and cultural exchanges. What makes the exploration special is the use of AI and robotic technology.Human divers cannot reach such depths safely,so underwater robots controlled by operators on the surface collect images,samples,and data.AI algorithms then analyze the materials,recognize cultural relics,and even help reconstruct the ships’ original shapes.This greatly improves efficiency and reduces damage to historical remains. Before modern technology,underwater archaeology was limited to shallow waters.Wrecks in deep seas were considered unreachable and were often damaged by time and human activities such as fishing and mining.Now,with precise positioning and low-impact collection methods,scientists can study these relics in their natural environment without destroying them. These shipwrecks show that China had advanced shipbuilding technology and active foreign trade hundreds of years ago.The goods found on board include products from China,Southeast Asia,and even West Asia,proving that ancient maritime routes were more complex and widespread than previously thought.They rewrite part of the history of global trade. However,exploring underwater cultural heritage also brings ethical challenges.Scientists must balance research with protection,making sure that exploration does not cause destruction.Some wonder whether technology is developing too fast for humans to fully understand the importance of what they discover. In the near future,more underwater unknowns will be uncovered.As we step into this new historical field,we must remember that exploration is not only about finding treasures but also about respecting history,protecting culture,and passing on wisdom to later generations. 28.What is the author’s attitude toward deep-sea archaeological exploration? A.Doubtful B.Supportive but cautious C.Uncaring D.Strongly critical 29.What makes deep-sea exploration more efficient and safer? A.Manual diving without any tools. B.AI and underwater robotic technology. C.Fishing boats and local equipment. D.Ancient maps and historical records. 30.What can we infer about ancient maritime trade? A.It was limited to nearby countries. B.It was more developed than known before. C.No porcelain was traded overseas. D.All ships were made of iron. 31.What is the best title? A.Unknown Deep Sea:History Under Water B.How to Build Ancient Ships C.The Dangers of Deep-Sea Fishing D.AI Replaces Human Archaeologists D In the AI era,human attitudes toward the unknown have changed greatly.With artificial intelligence,big data,and advanced tools,people can now predict,analyze,and prepare for risks that once frightened them.Yet curiosity,the oldest driving force behind exploration,remains as strong as ever.Psychologists and scientists are beginning to study how modern people balance fear,courage,and technology in the face of the unknown. Curiosity pushes humans to ask questions and take risks.It is the foundation of science,art,and all forms of progress.In the past,curiosity led people to sail across oceans and climb mountains.Today,it leads them to explore space,deep seas,and the human brain.However,without control,blind curiosity can lead to unnecessary danger and even destruction. Fear,on the other hand,is a natural protective system.It prevents people from acting carelessly and keeps them away from unnecessary risks.In ancient times,fear helped humans survive dangerous environments.Today,it still works as a warning system.However,too much fear stops growth.People who never leave their comfort zones seldom learn new skills or make breakthroughs. The rapid development of AI has added a new layer to this balance.AI can reduce uncertainty by providing data and predictions,making the unknown more manageable.It helps explorers plan routes,analyze dangers,and even simulate situations before real actions.This makes exploration safer but also raises questions:Will AI reduce human courage?Will people lose the ability to face real unexpected challenges? Experts believe that the healthiest attitude is to use technology as a tool,not a replacement for human spirit.True exploration in the 2020s requires curiosity,courage,preparation,and moral responsibility.It means stepping into the unknown not to conquer,but to understand,protect,and grow. As the world becomes more connected and technology continues to develop,the ability to face the unknown has become a necessary life skill.Whether in science,study,or daily life,those who can balance courage with caution will succeed.The unknown is not an enemy;it is a lifelong teacher. 32.What is the function of fear according to the passage? A.It pushes people to make quick progress. B.It protects people by warning of possible danger. C.It completely stops people from taking action. D.It makes people more creative. 33.What is the author’s suggestion for facing the unknown? A.Let curiosity control all decisions. B.Let fear stop all risky actions. C.Combine courage,preparation and technology. D.Stay in the comfort zone forever. 34.What influence may AI bring? A.It makes people completely fearless. B.It helps reduce uncertainty in exploration. C.It replaces all human spirits. D.It stops all scientific breakthroughs. 35.What can we infer from the text? A.The unknown will always be part of human growth. B.Technology can solve all problems in the world. C.Curiosity always leads to safe results. D.Fear has no value in modern society. 第二节 七选五 (共5小题；每小题2.5分，满分12.5分) 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。 The unknown has always attracted humans.It brings challenges,but also growth and discovery.Here are some ways to face the unknown bravely in the AI age.

At first,everything went smoothly.We walked along the marked path and took photos happily.But soon,my group stepped slightly off the path to examine a special rock.When we turned around,the road markers were gone.Thick woods surrounded us,and we had no phone signal. Some classmates felt worried and didn’t know what to do.I tried to stay calm.I recalled what our teacher had taught us:when lost in nature,look for reliable natural signs and stay together.We stopped moving randomly,checked the direction of sunlight,and followed a small stream downhill. After walking carefully for about twenty minutes,we caught sight of our teacher and other classmates.We were safe and relieved.This experience taught me that courage,calmness and teamwork can help us out of trouble.
