广东省广州市培正中学2026学年选择性必修一Unit3单元测试（9.9） 康社高二英语试题 （考试时间：65分钟；满分100分） 第1部分 阅读理解（共两节，满分30分） 第一节（共7小题；每题2.5分，满分17.5分） 阅读下列短文，从每题所给的A、B、C和D四个选项中选出最佳选项，并在答题卡上将该项涂黑。 A In the 1960s, while studying the volcanic history of Yellowstone National Park, Bob Christiansen became puzzled about something that, oddly, had not troubled anyone before: he couldn’t find the park’s volcano. It had been known for a long time that Yellowstone was volcanic in nature --- that’s what accounted for all its hot springs and other steamy features. But Christiansen couldn’t find the Yellowstone volcano anywhere. Most of us, when we talk about volcanoes, think of the classic cone (圆锥体) shapes of a Fuji or Kilimanjaro, which are created when erupting magma (岩浆) piles up. These can form remarkably quickly. In 1943, a Mexican farmer was surprised to see smoke rising from a small part of his land. In one week he was the confused owner of a cone five hundred feet high. Within two years it had topped out at almost fourteen hundred feet and was more than half a mile across. Altogether there are some ten thousand of these volcanoes on Earth, all but a few hundred of them extinct. There is, however, a second less known type of volcano that doesn’t involve mountain building. These are volcanoes so explosive that they burst open in a single big crack, leaving behind a vast hole, the caldera. Yellowstone obviously was of this second type, but Christiansen couldn’t find the caldera anywhere. Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption (假定) that they might make a nice blow-up for one of the visitors’ centers. As soon as Christiansen saw the photos, he realized why he had failed to spot the caldera: almost the whole park --- 2.2 million acres --- was caldera. The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans. 1. What puzzled Christiansen when he was studying Yellowstone? A. Its complicated geographical features. B. Its ever-lasting influence on tourism. C. The mysterious history of the park. D. The exact location of the volcano. 2. What does the second paragraph mainly talk about? A. The shapes of volcanoes. B. The impacts of volcanoes. C. The activities of volcanoes. D. The heights of volcanoes. 3. What does the underlined word “blow-up” in the last paragraph most probably mean? A. Hot-air balloon. B. Digital camera. C. Big photograph. D. Bird’s view. B According to a new study, AI chatbots tend to agree with their users so much that they often give bad advice, encouraging harmful behaviors and damaging personal relationships. The study tested 11 leading AI systems and found they all showed varying degrees of sycophancy --- behavior that was overly agreeable and supportive. Lead researcher Myra Cheng explained that the team launched the study after noticing more and more people were using AI for relationship advice and sometimes being misled by how it tends to take their side, no matter what. Her team compared the responses of popular AI assistants with the shared wisdom of humans on an advice website. It turned out that AI backed users’ improper actions 49% more often than humans did. The team also conducted experiments observing about 2,400 subjects, and they found those who shared their interpersonal dilemmas with AI chatbot became more certain they were right and less willing to repair relationships. Co-author Cinoo Lee pointed out that it meant they weren’t apologizing or changing their behavior, and he added the findings were especially significant for teenagers developing social and emotional skills through real-life interactions. Moreover, the harm doesn’t stop there --- it is widespread. In medical care, researchers say sycophantic AI could lead doctors to confirm their first judgment rather than encourage them explore further. In politics, it could strengthen more extreme positions by supporting people’s fixed opinions. Addressing sycophancy, however, is challenging. Sycophancy is so deeply embedded (嵌入) that tech companies may need to retrain their AI systems, said Cheng. A simpler fix could be instructing chatbots to challenge users more --- for example, by starting with “Wait a minute.” Lee also put forward the idea of a better AI: it could recognize users’ feelings and remind them to consider others’ emotions, or even encourage face-to-face communication instead of online chatting. That matters because the quality of social relationships is a key marker of health and well-being. Above all, we need AI that broadens people’s views rather than narrows them. 4. Why did Myra Cheng’s team start the study? A. AI assistants were often misled. B. Tech companies trained AI improperly. C. Advice websites worked poorly. D. People were blinded by AI’s sweet talk. 5. What harm may AI sycophancy bring about? A. Block relationship repairs. B. Change people’s fixed minds. C. Weaken original judgments. D. Mislead public medical opinions. 6. What is a possible solution to AI sycophancy? A. Recognize the limit of chatbots. B. Program AI to widen users’ views. C. Instruct chatbots to please users. D. Replace AI with face-to-face chats. 7. What is the main idea of the passage? A. Advice from AI needs a second thought. B. People depend heavily on AI for advice. C. Tech companies are improving AI systems. D. AI chatbots are challenging users’ opinions. 第二节（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。选项中有两项为多余选项。 In discussions about student success, those who have experienced the arts understand the unique value music education holds. _____8_____ Actually, it is a powerful, practical tool that solves challenges fa beyond the music room.
