What if that idea could become a reality and actually make a difference? That's exactly what the 17-year-old Ryan Honary from the US achieved．He is a finalist of the Earth Prize 2024 competition，which is the world's largest environmental sustainability contest for people aged 13－19．Ryan's invention，called Sensory AI，can spot fires as small as one square foot．Thanks to it，firefighters can act before a fire turns into a disaster． Ryan came up with the idea after the California wildfire in 2018，which destroyed 18，000 homes and structures．In February，he introduced his innovative wildfire sensor to the Orange County Fire Authority(OCFA) in Irvine，California，US．This development comes at a crucial time following recent wildfires worldwide，from Los Angeles to Portugal，as communities seek solutions for future threats，reported The Express Tribune． After a frightening experience trying to contact a family to confirm they were safe in the wildfire，Ryan started thinking about reworking a heat detector from a fifth-grade school project．Through gradual improvements with infrared (红外线) sensors，a wireless sensor network，artificial intelligence，machine learning，and a camera to detect smoke，the solution caught the attention of the OCFA．This cost-effective solution，suitable for high-risk areas，can be easily expanded to other locations in need of enhanced monitoring． The initial installation stage targets high-risk zones within the Irvine Open Space Preserve，a crucial ecological corridor of nearly 40，000 acres of open space．This preserve，jointly managed by OC Parks，connects Orange County's open areas to the Cleveland National Forest． “Finding fires early is crucial all year round．It helps firefighters respond quickly and safely to stop wildfires from growing big，”explained OCFA Fire Chief Brian Fennessy to Earth．org．“I believe that young people should be going beyond talking and really focus on developing practical solutions，”said Ryan． 1．What is the main function of Sensory AI?

A．To describe a fact． B．To introduce the study． C．To explain an issue． D．To present an opinion． 6．What is paragraph 2 mainly about? A．The findings of the analysis． B．The symptoms of the vets． C．The causes of H5N1 bird flu． D．The basic logic of the study． 7．What surprised Seema Lakdawala the most? A．The infected vets'unawareness of the issue． B．The 17% infection rate among dairy workers． C．The high number of positive test results in vets． D．The risk of unrecognized infections in cows and vets． 8．What aspect should be improved in the follow-up study? A．The size of the tested group． B．The individual samples． C．The data analysis procedure． D．The measuring method． C (2025·江西九江二模) The release of DeepSeek-R1 has sent shockwaves through the AI industry，reshaping assumptions about the cost of high-performance AI．Achieving results comparable to OpenAI's o1 at just 3%－5% of the cost，this open-source model has gained immense popularity，topping downloads on HuggingFace and trending among developers eager to explore its capabilities． A major innovation behind DeepSeek-R1 is its unconventional training approach．Unlike traditional models that rely heavily on supervised fine-tuning (SFT) for step-by-step learning，DeepSeek-R1 was mainly trained using reinforcement learning (RL)．This allowed it to develop independent reasoning abilities，rather than relying on pre-set training data．While some SFT was reintroduced later to address readability and language issues，the success of RL in enhancing reasoning performance marks a breakthrough in AI training methodology． DeepSeek's rapid progress also shows its smart use of resources．Operating with far fewer GPUs than OpenAI and Google，it took advantage of open-source projects，such as Meta's Llama models，and used advanced techniques like mixed-precision training and optimized (优化) GPU communication．Although the exact costs remain uncertain，estimates suggest DeepSeek-R1 was created on a much smaller budget than usual，proving that cutting-edge AI does not necessarily require massive financial investment． Another key advantage of DeepSeek-R1 is its transparency (透明性)．Unlike OpenAI's models，which hide their reasoning process，DeepSeek-R1 openly displays its thought process，making it easier for developers to find mistakes and improve results．This has fueled interest in using DeepSeek to fine-tune smaller，task-specific AI models，making powerful AI tools more accessible． However，DeepSeek's dominance is not guaranteed．Open-source innovation moves quickly and rivals like Meta and Mistral are expected to adopt similar breakthroughs soon．Meanwhile，OpenAI's massive investments，including its $500 billion Stargate project，face growing inspection as cost-efficient alternatives emerge． Despite concerns over potential biases in DeepSeek's model，many developers see these as manageable through fine-tuning．Ultimately，businesses and consumers stand to benefit the most，as the increasing availability of high-quality，low-cost AI tools challenges the industry's traditional power structure． 9．Why is DeepSeek-R1 so popular? A．It is more convenient． B．It dominates AI industry． C．It is more cost-effective． D．It can achieve better results． 10．What can we learn about DeepSeek-R1 in paragraph 2? A．Its training datasets． B．Its reasoning abilities． C．Its training method． D．Its processing language． 11．Why is DeepSeek-R1 considered more transparent than OpenAI's models? A．It makes all of its training data publicly available． B．It reveals the full chain of reasoning behind its answers． C．It is designed to answer any question without restrictions． D．It can use reinforcement learning methods to improve results． 12．What is the author's purpose in writing the text? A．To introduce DeepSeek-R1． B．To call for investments in AI． C．To warn about the risks of AI． D．To clarify reinforcement learning． 高频词汇 A篇：reality n．现实；实际情况sustainability n．可持续性disaster n．灾难；灾祸 crucial adj．至关重要的contact vt．联络confirm vt．证实expand v．扩展；扩大 B篇：circulate v．传播；循环undetected adj．未被发现的symptom n．症状 outbreak n．爆发 C篇：assumption n．假设immense adj．极大的，巨大的popularity n．流行，普及，受欢迎ultimately adv．最终 熟词生义 A篇：spot(常见义) n．地点；斑点 (文中义)　v．发现；识别 B篇：positive (常见义) adj．乐观的，积极的 (文中义) n．阳性结果 C篇：release(常见义) vt．释放；发布(消息、产品等) (文中义) n．上市，发行fuel(常见义) n．燃料 (文中义) vt．激发，促进(兴趣) address (常见义) n．地址；演讲 (文中义) vt．处理，解决 重点短语 A篇：come up with想出；提出(主意、计划等)in need of需要 B篇：on the one hand...on the other hand一方面……另一方面 C篇：rather than而不是 难句分析 B篇：A new study published by the U．S．Centers for Disease Control and Prevention (CDC) shows that the H5N1 bird flu virus is probably circulating undetected in domestic animals in many parts of the country and may be infecting uninformed vets． 结构分析： 主干结构：A new study shows that... published by the... 是过去分词短语作后置定语，修饰“study”。 宾语从句包含两个并列谓语：is circulating 和 may be infecting。 译文：美国疾病控制与预防中心(CDC)发表的一项新研究表明，H5N1禽流感病毒可能在美国许多地区的家畜中传播而未被发现，并可能感染了不知情的兽医。 C篇：Achieving results comparable to OpenAI's o1 at just 3%－5% of the cost，this open-source model has gained immense popularity，topping downloads on HuggingFace and trending among developers eager to explore its capabilities． 结构分析：“Achieving results...”是动词-ing形式短语作状语；“comparable to OpenAI's o1”是形容词短语作后置定语，修饰“results”；“topping downloads...”和“trending among...”是动词-ing形式短语作伴随状语。 译文：这种开源模式获得了与OpenAI的o1相媲美的结果，而成本仅为OpenAI的3%到5%，它获得了巨大的人气，在HuggingFace上的下载量高居榜首，并成为渴望探索其功能的开发者的热门。 1 / 7 学科网（北京）股份有限公司 $
