It was developed by DeepSeek, a Chinese business based in Hangzhou, Zhejiang province. The new AI was r 1 on Jan 20. In just one week, it beat OpenAI’s ChatGPT and became the top free application (应用) in Apple’s App Store, reported Xinhua. Its developer said that DeepSeek-R1 is as good at difficult tasks as other big models but needs less computing power (算力). It is also the c 2 of its kind and took only about 5.57 million US dollars (40.58 million yuan) to develop. That is way less than the hundreds of millions or even billions that US businesses have had to spend on building similar AI models, Marc Andreessen, a technology expert in the US, told Xinhua. DeepSeek-R1’s success largely came from its s 3 training way. Traditionally, AI is trained in two ways. One is Chain-of-Thought (CoT，思维链), where AI learns to break problems into smaller, simpler steps. The other is Supervised Fine-Tuning (SFT，监督微调), which works by showing AI lots of practice problems along with the right answers for it to find a pattern. DeepSeek-R1, h 4 , used Reinforcement Learning (RL，强化学习) as the key way, Xinhua reported. In R1, AI learns by trying different things. It gets rewards for correct actions and gets punished (受到惩罚) for m 5 . For example, in a game, it gets points for picking up trash and loses points for breaking a glass. Over time, it works out the best solution all by i 6 . This is how DeepSeek-R1 has grown to be a reasoning model, which is a new type of AI, noted Microsoft engineer Vinayak Hegde. Regular AI models, like GPT-40, usually just give direct answers. But reasoning models are trained to b 7 think and show the process. 【答案】1．(r)eleased 2．(c)heapest 3．(s)pecial/(s)uper/(s)uperior 4．(h)owever 5．(m)istakes 6．(i)tself 7．(b)oth/(b)etter/(b)est) 【导语】本文主要介绍了由中国浙江杭州的DeepSeek公司开发的新型人工智能模型 DeepSeek-R1.0。它于1月20日发布，一周内就超越了OpenAI的ChatGPT成为苹果应用商店中排名第一的免费应用。该模型在完成困难任务时表现出色且所需算力少、开发成本低。其成功主要源于独特的训练方式——强化学习，通过不断尝试、因正确和错误行为获得奖惩来自己找到最佳解决方案，进而成长为一种新型的推理模型，这种模型与普通模型不同，能更好地思考并展示过程。 1．句意：新的人工智能于1月20日发布。根据“The new AI was...on Jan 20.”及首字母提示可知，这里说新人工智能在1月20日被发布，“release”表示“发布”，此处是一般过去时的被动语态“was+过去分词”，所以用“release”的过去分词“released”。故填(r)eleased。 2．句意：它也是同类产品中最便宜的，开发成本仅约557万美元（4058万元人民币）。根据“It is also the...of its kind and took only about 5.57 million US dollars (40.58 million yuan) to develop.”及首字母提示可知，后面提到开发成本仅需557万美元，说明它是同类中最便宜的，“cheapest”是“cheap”的最高级形式，表示“最便宜的”。故填(c)heapest。 3．句意：DeepSeek-R1的成功很大程度上源于其特殊的/超级的/优越的训练方式。根据“DeepSeek-R1’s success largely came from its s...training way.”及首字母提示可知，这里表示它成功源于某种训练方式，结合后文介绍其独特训练方式可知，special、super、superior都符合语境，表示其训练方式与众不同、很棒 。故填(s)pecial/(s)uper/(s)uperior。 4．句意：然而，据新华社报道，DeepSeek-R1使用强化学习（RL）作为关键方法。前文提到传统人工智能的训练方式，这里说DeepSeek-R1使用不同的训练方式，前后是转折关系，“however”表示“然而”，用于句中时常用逗号隔开。故填(h)owever。 5．句意：它因正确的行为得到奖励，因错误受到惩罚。根据“It gets rewards for correct actions and gets punished (受到惩罚) for...”及首字母提示可知，这里说正确行为有奖励，与之相对应的是错误行为会受惩罚，“mistake”表示“错误”，这里用复数形式“mistakes”。故填(m)istakes。 6．句意：随着时间的推移，它完全靠自己找出最佳解决方案。根据“Over time, it works out the best solution all by...”及首字母提示可知，“by oneself”是固定短语，表示“独自，靠自己”，这里主语是“it”，其反身代词是“itself”。故填(i)tself。 7．句意：但推理模型经过训练能够更好地思考并展示过程。/但推理模型经过训练能够全面思考并展示过程。根据“But reasoning models are trained to...think and show the process.”及首字母提示可知，这里说推理模型与普通模型不同，能在思考和展示过程方面有更好的表现。“both”表示“两者都”，表示推理模型能同时做到思考和展示过程；“better”是“well”的比较级，表示能更好地思考和展示过程；“best”是“good”的最高级，也符合语境。故填(b)oth/(b)etter/(b)est)。 Racing into the future In 2024, we saw many new scientific achievements. What can we expect in 2025? Mind-reading machines In 2025, China plans to make brain-computer interface (BCI，脑机接口) devices (设备) to help people in different ways, like in medicine and virtual reality (虚拟现实). NEO, one device made by Chinese scientists, is a wireless (无线的) BCI with eight small parts that connect to the brain. It helps people who can’t move their hands to use t 1 again. AI agents AI, or artificial intelligence, is changing the world a lot. AI agents, which can see what’s around them and make choices by themselves, are becoming important. AI agents can help with “easy” jobs like filling out reports. Then, as we make b 2 ones, they will be able to watch and control systems on their own. For example, an AI agent app can help plan your summer trip by booking flights, hotel rooms, and restaurant tables. It even r 3 that you like hotels with pools. Space p 4 Space traffic this year will be as busy as that in 2024. China completed its first space mission of the year on Jan 7 with a Long March 3B rocket. In 2025, our country will complete Shenzhou manned missions and Tianzhou cargo (货物) missions to the Tiangong space station. A 5 , China and the European Union will work together to send the SMILE satellite into space in order to study the solar wind and get a deeper understanding of the Sun-Earth relation. Going clean Due to climate change, 2024 was the hottest year on record. Because of this, g 6 technology has become more important than ever. One key technology is carbon capture and storage (CCS，碳捕获与储存). It works by taking CO₂ away from other gases at factories before people r 7 the gases into the air, and transporting the CO₂ to an underground site. By October 2024, CCS projects had held about 45 million tons of CO₂ every year, equaling the emissions of 10 million cars. In 2025, clean energy is set to be used more for power than coal. 【答案】1．(t)hem 2．(b)etter 3．(r)emembers 4．(p)lans 5．(A)lso 6．(g)reen 7．(r)elease 【导语】本文展望了2025年的科学发展方向，包括脑机接口、人工智能、太空探索及绿色能源等领域的新成就。 1．句意：它帮助那些不能动手的人再次使用它们。根据句中“people who can’t move their hands”可知，所指代的是“hands”，应用代词代替；结合首字母t提示，应填them。故填(t)hem。 2．句意：然后，随着我们制造出更好的（AI系统），它们将能够自己监控和控制系统。根据句中“they will be able to watch and control systems on their own.”可知，此处表示“更好的”，结合首字母b提示，应填better。故填(b)etter。 3．句意：它甚至会记住你喜欢带游泳池的酒店。根据句中“that you like hotels with pools”可知，动词应表示“记住”，结合首字母r，应填remembers，作谓语动词。时态为一般现在时，主语it为第三人称单数。故填(r)emembers。 4．句意：太空计划。根据“In 2025, our country will complete Shenzhou manned missions and Tianzhou cargo (货物) missions to the Tiangong space station.”和“China and the European Union will work together to send the SMILE satellite into space in order to study the solar wind and get a deeper understanding of the Sun-Earth relation.”描述中国将要完成的多项任务可知，此处应填名词，表示“计划”，结合首字母p，应填plan，此处表泛指，用其复数形式。故填(p)lans。 5．句意：中国和欧盟也将合作发射SMILE卫星，以研究太阳风并更深入地了解太阳与地球的关系。根据“In 2025, our country will complete Shenzhou manned missions and Tianzhou cargo (货物) missions to the Tiangong space station. ”和“China and the European Union will work together…”可知，此处表示“也、同时”，结合首字母A，应填also，符合语境。故填(A)lso。 6．句意：因此，绿色技术比以往任何时候都更重要。根据句中“Due to climate change, 2024 was the hottest year on record.”及首字母g提示可知这是关于环保的，应填green，意为“环保的，绿色的”，作形容词修饰technology。故填(g)reen。 7．句意：它通过在工厂排放前从其他气体中去除二氧化碳，并将二氧化碳运输到地下场所来工作。根据句中“before people…the gases into the air”可知，此处动词表示“释放、排放”，结合首字母r，应填release，作动词使用，时态为一般现在时，主语people为复数，用动词原形。故填(r)elease。 2 / 17 1 / 17 学科网（北京）股份有限公司 $$ Unit 4 Computers 单词短语句型语法（教材考点精练） 一、单项选择，每小题1分，满分15分 1．Of all the students in my class, she writes _________.

It was developed by DeepSeek, a Chinese business based in Hangzhou, Zhejiang province. The new AI was r 1 on Jan 20. In just one week, it beat OpenAI’s ChatGPT and became the top free application (应用) in Apple’s App Store, reported Xinhua. Its developer said that DeepSeek-R1 is as good at difficult tasks as other big models but needs less computing power (算力). It is also the c 2 of its kind and took only about 5.57 million US dollars (40.58 million yuan) to develop. That is way less than the hundreds of millions or even billions that US businesses have had to spend on building similar AI models, Marc Andreessen, a technology expert in the US, told Xinhua. DeepSeek-R1’s success largely came from its s 3 training way. Traditionally, AI is trained in two ways. One is Chain-of-Thought (CoT，思维链), where AI learns to break problems into smaller, simpler steps. The other is Supervised Fine-Tuning (SFT，监督微调), which works by showing AI lots of practice problems along with the right answers for it to find a pattern. DeepSeek-R1, h 4 , used Reinforcement Learning (RL，强化学习) as the key way, Xinhua reported. In R1, AI learns by trying different things. It gets rewards for correct actions and gets punished (受到惩罚) for m 5 . For example, in a game, it gets points for picking up trash and loses points for breaking a glass. Over time, it works out the best solution all by i 6 . This is how DeepSeek-R1 has grown to be a reasoning model, which is a new type of AI, noted Microsoft engineer Vinayak Hegde. Regular AI models, like GPT-40, usually just give direct answers. But reasoning models are trained to b 7 think and show the process.
