B In 1962, American biologist Rachel Carson published Silent Spring, a book that would change how people viewed nature. It warned that the harmful and uncontrolled use of pesticides (杀虫剂) was poisoning the environment and could lead to a silent spring without birdsongs. The book caused immediate debate. Chemical companies campaigned against it strongly, as Carson’s warnings threatened their established and profitable practices. Despite this opposition, the book raised global awareness about how easily nature can be harmed. Carson’s deep connection to nature began in her childhood in Pennsylvania, where she explored the woods and streams near her home. This passion led her to study biology, which gave her the scientific knowledge she would later use in her writing. Before Silent Spring, Carson was a marine biologist and writer. She spent four years carefully researching for the book, gathering evidence from scientific studies and talking to farmers and fishermen who had seen the effects of pesticides. She built a strong argument based on data and personal accounts. Knowing her work would be criticized, Carson believed the public had the right to know the truth. She continued her efforts even while she was sick, and she died in 1964. However, her influence lived on. Silent Spring inspired the modern environmental movement, led to the ban of DDT in the U.S., and made sure her legacy would last as a pioneering environmentalist. 4. Why did chemical companies campaign against Silent Spring? A. They found numerous scientific errors in the book. B. Carson refused to share her research data with them. C. They believed the book would confuse the general public. D. Carson’s warnings posed a threat to their business interests. 5. How did Carson’s personal background contribute to her environmental work? A. Her career as a writer provided her with the funding needed for research. B. Her work as a marine biologist directly exposed her to pesticide pollution. C. Her family’s farm gave her practical experience in using agricultural chemicals. D. Her childhood experiences and formal education in biology shaped her advocacy. 6. The text suggests that Carson’s research for the book was characterized by its ________. A. comprehensiveness and various sources B. reliance on government reports C. focus on theoretical models D. speed and efficiency 7. What is the main idea of the text? A. The scientific process behind banning DDT. B. The remarkable and lasting impacts of Rachel Carson’s book. C. The history of pesticide use in the United States. D. The debate between environmentalists and chemical companies. C It was the summer before junior year. I was a waitress at a little restaurant. My duties were straightforward: taking orders, delivering food and cleaning tables. I got really good at managing multiple tasks, and having a lot of responsibilities made me more responsible. These values and skills are what numerous studies hold up as the important reasons why teenagers should work during the summer. They’re what teachers mention when they encourage us to get jobs. I developed those skills. But I don’t think that’s the main benefit high school students get from working. So much happened in the interstitial (空隙的) time and spaces between our roles as waitresses, cooks and customers. This is where I think the value of a high school job lies: learning how to form a community with people I never would have otherwise known. High school students spend about seven hours a day in classes, and then often stay afterward for school-sponsored sports or activities. It’s not necessarily a bad thing to be wrapped up in school. But what I find is that a job can serve as a relief from the academic tasks of high school. This relief came not from avoiding people, but from engaging with a community I would never have found in the halls of my high school. The people I met at the restaurant taught me that you can become friends with those decades older than you and strangers who have none of the same interests or hobbies as you do. They taught me that you can wildly disagree with someone and still respect them, learn from them, and love them. 8. What is commonly believed to be the main benefit teenagers get from work? A. Earning money for college. B. Learning to form a community. C. Developing responsibility and skills. D. Making friends with different people. 9. What does the author say about high school life? A. It lacks meaningful activities. B. It focuses on academics. C. It is highly school-centered. D. It provides adequate social opportunities. 10. What did the author learn from people at the restaurant? A. Friends should share similar interests. B. Workplace relationships are temporary. C. True friendship requires constant agreement. D. Meaningful connections can bridge differences. 11. What is the author’s main conclusion about her job experience? A. It helped improve her academic performance. B. Its greatest value went beyond skill development. C. It confirmed traditional views about student jobs. D. Its main benefit was earning teachers’ approval. D Sharks are dying at staggering rates, primarily due to fishing activities. Nearly one-third of shark species globally are threatened with extinction. While some sharks are intentionally targeted, more than half are caught incidentally as bycatch and later thrown away, contributing significantly to their decline. In response, regional fisheries management organizations have introduced retention (留存) bans that require fishermen to release accidentally captured sharks. Currently, 17 oceanic shark species are protected under such bans in tuna fisheries. A research team from UC Santa Barbara collected data from over 150 published studies covering nearly 150 species to estimate mortality (死亡) rates for caught and released sharks. Their findings revealed particularly high post-release mortality among certain groups: smaller sharks, deep-water species, and those requiring constant swimming to breathe. Notably, thresher sharks, hammerheads, and smoothhound sharks showed mortality rates ranging from 30% to 65%. The study demonstrated that while retention bans could reduce shark mortality by three times on average, this reduction remained insufficient to achieve sustainable levels for heavily fished species such as mako and silky sharks. The authors stress that retention bans are a good first step, but they must be combined with other measures. These include changing fishing gear (for example, not using steel wires in longline fishing), protecting key shark habitats (especially areas where young sharks are born and grow up), and setting limits on how many sharks can be caught. Such comprehensive approaches are essential for effective shark conservation. Moreover, the researchers point out that we know very little about related fish with cartilaginous fishes — such as rays, skates, and chimaeras. These fishes face similar threats of extinction, but there are not enough studies on how many die due to fishing. The research team is now working with international tuna organizations to encourage conservation talks and find effective mixes of policies. 12. What does the underlined word “staggering” in paragraph 1 probably mean? A. Safe. B. Steady. C. Alarming. D. Declining. 13. Retention bans require fishermen to ________. A. avoid fishing in shark habitats B. release accidentally caught sharks C. use special equipment to protect sharks D. limit the number of sharks caught per year 14. Which sharks are most likely to die after being released? A. Deep-water species. B. Large species near the coast. C. Those living in shallow waters. D. Species with slow reproductive rates. 15. What is paragraph 5 mainly talking about? A. Broader measures are needed to protect sharks effectively. B. Fishing bans in saving all shark species are successful. C. The retention bans need to be changed completely. D. Focusing only on young sharks is important. 第二节（共5小题；每小题2.5分，满分12.5分） 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 We all know that protecting our eyes is important. However, many students tend to ignore the warning signs of eye tiredness. ____16____ Nowadays, eye overuse has become a very common phenomenon. ____17____ It usually results from not following the 20-20-20 rule (looking at something 20 feet away for 20 seconds every 20 minutes), studying in poor lighting conditions, holding books too close to your eyes, or not blinking (眨眼) enough while focusing. What happens when you don’t give your eyes enough rest? In the short term, it can cause eye strain (疲劳) and headaches. The discomfort associated with eye overuse can lead to difficulty concentrating, reduced learning efficiency, and a lack of interest in reading. ____18____ Such discomfort typically includes dry eyes, blurred vision, and increased sensitivity to light. In the long term, it can potentially worsen nearsightedness. While eye strain can be troubling, the good news is that you can prevent most of these problems. ____19____ Specifically, start practicing the 20-20-20 rule today, which may be simple enough to help your eyes relax and maintain good eyesight. After you’ve formed this good habit, make sure you’re also maintaining proper reading distance and lighting. If you drove a car without ever checking the engine, you’d eventually break down, right? The same goes for your eyes. Just like a car, your eyes need proper care and regular maintenance to keep functioning well — not only when you use them intensively during study sessions but throughout your entire daily life. ____20____ A. Therefore, be cautious during your study time. B. The first thing you can do is develop good habits. C. You may also experience physical eye discomfort. D. Eye overuse means not giving your eyes enough rest. E. In fact, ignoring eye discomfort can lead to serious problems. F. Wearing proper glasses is essential if you have vision problems. G. So, give them proper rest, nutritious support, and professional care when needed. 第三部分 语言运用（共两节，满分30分） 第一节（共15小题；每小题1分，满分15分） 阅读下面短文，从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 In Westmoreland, Tennessee, a potentially dangerous situation turned into a heartwarming success, all thanks to teamwork and modern technology.

Last year, my dream came true when I joined a course for flying with a parachute (滑翔伞) in the mountains. My instructor, Karl, was a patient and experienced teacher. During our ground training on a small hill, he repeated his most important lessons: “If you get into trouble, first, stay calm. Second, listen to my voice. Most importantly, you must have gentle but firm control over the controls. And remember to slow down just before landing. One more thing — be ready to change your plan. If your direction changes, look for the nearest open space to land.” I learned to trust him completely. It was this trust that saved me once. It was a sunny day with a gentle breeze. As we took the cable car up, Karl pointed to a large, open field far below. “That is our target landing zone,” he said. At the launch site, he checked my equipment and gave me a confident smile. “The wind is perfect. Just run straight ahead and don’t stop. I will be right here on your radio, guiding you.” His presence made me feel safe. I took a deep breath and ran. The wind lifted me, and I was flying! The view was breathtaking. I felt a strong sense of freedom, but I kept Karl’s voice in my mind, carefully following his gentle directions through the radio. However, the mountain weather changed instantly. Dark clouds gathered, and the friendly wind turned into a roaring monster, shaking my wing. Karl’s voice became urgent. “Lisa, bad weather is coming! You must land now! Try to turn towards the large field and keep in touch with me!” I tried, but a powerful wind caught my wing, pushing me wildly off course. The safe field slipped away, and the dark outline of a large forest rushed toward me. 注意：1.续写词数应为150个左右； 2.请按如下格式在答题卡的相应位置作答。 I struggled to control my parachute in the strong wind. _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Suddenly, I saw that small open area below that Karl just said. _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 2025~2026高二期中学生能力评价 英语 考生注意： 1. 本试卷分选择题和非选择题两部分。满分150分，考试时间 120分钟。 2. 答题前，考生务必用直径0.5毫米黑色墨水签字笔将密封线内项目填写清楚。 3. 考生作答时，请将答案答在答题卡上。选择题每小题选出答案后，用2B铅笔把答题卡上对应题目的答案标号涂黑；非选择题请用直径0.5毫米黑色墨水签字笔在答题卡上各题的答题区域内作答，超出答题区域书写的答案无效，在试题卷、草稿纸上作答无效。 4. 本卷命题范围：至选择性必修第三册。 第一部分 听力（共两节，满分30分） 第一节（共5小题；每小题1.5分，满分7.5分） 听下面5段录音。每段录音后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项。听完每段录音后，你都有10秒钟的时间来回答有关小题和阅读下一小题。每段录音播放两遍。 1.

The event included various activities such as waste sorting guidance, used item recycling, and campus cleaning. Students actively participated in collecting recyclables and cleaning up the schoolyard. They also learned how to classify different types of waste correctly. The activity was highly praised by both students and teachers. Many said they not only gained practical knowledge but also felt a sense of achievement in contributing to a greener campus. We believe this event will inspire everyone to continue protecting the environment in daily life. 第二节（满分25分） 【47题答案】 【答案】 I struggled to control my parachute in the strong wind. Fear filled my heart as the forest came closer and closer. My hands shook, but Karl’s calm voice helped me. “Lisa, you can do this. Remember your training,” he said. His words gave me strength. I tried to breathe slowly and stay focused. The wind was strong, but Karl was with me, guiding me. Then I heard him say, “Look for any open space below. There might be a small clearing near the forest.” Suddenly, I saw that small open area below that Karl just said. New hope rose in my heart. I quickly told Karl through the radio, “I see it! I see the clearing!” “Yes! Go there!” Karl’s voice was full of support. I tried my best to move toward it. The ground came up fast, and I remembered Karl’s words: stay calm. I landed hard but safely in the clearing. My legs were shaking as I sat on the grass. “You did it!” Karl said through the radio. Tears ran down my face. I had learned to trust—in Karl and in myself. 第1页/共1页 学科网（北京）股份有限公司 $
