习题讲评(一)　主题阅读训练 A (2025·开封模拟)Advances in artificial intelligence (AI) are indicating that accurate quake forecasting may be attainable, thereby casting doubt on the conventional wisdom that such an accomplishment is beyond our capabilities. Researchers at the University of Texas, Austin, created an AI model that, during a test run in China, correctly forecasted approximately 70 percent of earthquakes with a one­week warning and offered reliable assessments of their potential intensity. The researchers attribute their technique's effectiveness to its reliance on a straightforward machine leaning framework. The AI was provided with a set of statistical features based on the team's knowledge of earthquake physics, and then instructed to train itself using a five­year database of earthquake recordings. Once trained, the AI offered predictions by detecting early indicators of quakes hidden within the planet's low­frequency rumbles (隆隆声)． The project marks a substantial breakthrough in the exploration of AI for anticipating seismic (地震) events. According to Alexandros Savvaidis, a senior researcher heading the Texas Seismological Network, “Seismic occurrences strike without warning, often in the blink of an eye. Your readiness is all you can influence. Achieving a 70% prediction rate is a considerable achievement that could significantly restrict the impact of earthquakes, reducing both the financial burden and loss of life, and the potential to remarkably improve earthquake preparation worldwide.” Although the effectiveness of this method in different regions remains uncertain, the researchers believe that their AI model has the potential to enhance prediction accuracy when carried out in regions equipped with dependable seismic monitoring facilities. Their next step is to test artificial intelligence in Texas, where the University of Texas's TexNet operates a network of 300 earthquake stations and over six years' worth of continuous records, making it an ideal location for these purposes. Ultimately, the authors aim to combine the system with physics­based models. This approach could be particularly valuable in areas characterized by limited or inadequate data. “That may be a long way off, but many advances such as this one, taken together, are what moves science forward，” concludes Scott Tinker, the bureau's director. 语篇解读：本文是一篇说明文。文章主要说明了人工智能可以给出准确的地震预测，并介绍了其工作原理以及意义。 1．How does the AI predict seismic events?

For their experiments, fire expert Thomas H. Fletcher and co­authors loaded leaves of 14 plant species into the crucible (坩埚) of a thermo gravimetric analyzer (热重分析仪) and slowly turned the heat up to 800 degrees Celsius. As they watched the leaves burn, they categorized the speed at which the plant broke down and the chemicals produced by the heat. They also compared the impact of two heat sources: convective (think of wind­driven fires) and radiative (from burning plant particles or flames)． The research found that the chemistry of plants makes a big difference in how fast they break down before they start to burn. That's important to know because the type of plant found on a mountain hillside may help predict how a fire will burn and how quickly it might jump to another plant species. “Very detailed models that already exist take up to two weeks to run on very big computers and by that time, the fire has moved and it's not in the same place anymore，” Fletcher said. “We're aiming towards giving answers on how a fire might propagate in the next 20 minutes or half hour instead of the next two weeks.” The studies are aimed at improving predictive models for both prescribed (有计划的) burns and for unplanned wildfires. With wildfires costing the Forest Service and state agencies billions of dollars to control annually, any research that can help make fire management more efficient is a high priority. “With all we've done to research them, fires are still out of control，” Fletcher said. “Our model can't prevent a fire, but it can help with decisions on how to manage fires so that when a fire starts, it doesn't blow up into a huge, uncontrollable fire.” 语篇解读：本文是一篇说明文。文章介绍了杨百翰大学火灾研究实验室的一项新研究正在深入研究火灾是如何发生的微观细节，以提供更多关于野火如何通过荒地燃料燃烧的信息。 5．What is paragraph 2 mainly about? A．The research subjects. B．The research findings. C．The research procedures. D．The research objectives. 解析：选C　段落大意题。根据第二段内容可知，第二段主要介绍了Thomas H. Fletcher和合著者开展研究的具体步骤。 6．What does the research find about the chemistry of plants? A．It affects the speed of a fire. B．It is one of the causes of a fire. C．It breaks down quickly in a fire. D．It helps plants survive in a fire. 解析：选A　细节理解题。根据第三段内容可知，研究发现植物的化学成分影响其燃烧前的分解速度，进而影响火灾发生的速度。 7．What does the underlined word “propagate” in paragraph 4 mean? A．Explode.　　　　　　 B．Spread. C．Die down. D．Break out. 解析：选B　词义猜测题。根据画线词所在句的上文可知，已经存在的非常详细的模型的弊端在于其耗时过久，导致无法对已经转移的火灾进行管理，再结合画线词的上文“We're aiming towards giving answers”和下文“in the next 20 minutes or half hour instead of the next two weeks”可推知，Fletcher的研究目的是在很短的时间内给出火灾如何扩散、蔓延的答案，确保模型的时效性，画线词意思应该是“传播，扩散”，与spread意思相近。 8．Why do the researchers develop the new model? A．To make the most out of wildfires. B．To control wildfires more efficiently. C．To predict the outbreak of wildfires. D．To prevent wildfires from happening. 解析：选B　细节理解题。根据最后一段尾句可知，研究者开发该新模型是为了更有效地控制野火。 习题讲评(二)　语用综合训练 　　　　　　　　　　　　　　　　 Ⅰ.语法填空 (2025·咸阳模拟)Chinese achievements in pollution control, ecological recovery and protection, and green development China 1 (make) in the past decade were highlighted at a Friday press briefing, 2 a senior official pointed out China's 3 (participate) and leadership in global climate governance.

His little dog, Lucky, cheerfully ran around trying to catch the ball whenever Fern kicked it too far. The air was filled with laughter and barks, making it sound like a perfect day. All of a sudden, the sky changed color, turning dark gray. Fern noticed the wind picking up, and the trees began to shake wildly. He looked towards the horizon and saw a terrifying scene — a tornado coming towards the town. Fern fought panic and grabbed Lucky quickly. He remembered what the TV weatherman had said: “If you meet a tornado, head for the storm cellar (地窖) immediately.” Lucky whined and struggled in Fern's arms. “Steady, boy，” Fern said to Lucky. As he reached the doorstep of the storm cellar, he thought of Mrs. Smith, the elderly neighbor next door. Mrs. Smith lived alone and moved slowly because of her leg problems. Should he check on her? But what could he do? It seemed unlikely that she could make it to the storm cellar quickly enough. Plus, he wasn't even sure if she wanted him around. She often scolded (训斥) him because his dog, Lucky, would mess up her flower gardens. But if there was a tornado ..., she didn't have a basement or a storm cellar. Fern knew he couldn't just leave her there. “Sorry, Lucky.” He set the shaking dog on the steps in the storm cellar and let the door drop shut. Lucky would be scared there by himself, but he'd be safe. 注意：1.续写词数应为 150左右； 2．请按如下格式作答。 He had to make sure Mrs. Smith was OK.　 　 　 After what felt like hours, the tornado finally stopped.　 　 　 　 　 　 参考范文： He had to make sure Mrs. Smith was OK. Fern ran out of the storm cellar, ignoring the howling wind and flying debris(碎片). He ran towards Mrs. Smith's house, heart pounding in his chest. As he neared her home, he could see her door swinging open and a chair overturned in the yard. With effort he pushed through the door and called out for her. “Mrs. Smith, are you here？” he shouted, his voice trembling. The house was empty, but he spotted her in the backyard, struggling to get up from the ground. She had fallen and was unable to move due to her leg problems. Fern quickly ran to her side and helped her up. “Let's go to my house，” he said, grabbing her arm and guiding her towards his backyard. After what felt like hours, the tornado finally stopped. Fern and Mrs. Smith emerged from the shelter of his backyard, blinking in the bright sunlight that had replaced the dark, stormy sky. The town of Oakville was in disorder, with trees down and houses damaged. But Fern felt a sense of relief and accomplishment as he looked at Mrs. Smith standing beside him, safe and unharmed. He had done what he could to help his neighbor in need, and it had been worth it. He turned to Lucky, who was wagging his tail and jumping up and down, and gave him a big hug. “We did it, boy，” he said, smiling. 7 / 7 学科网（北京）股份有限公司 $$
