In 2025, a team of scientists from China developed a new environmental tech called “Solar-Powered Algae (藻类) Mats” (SPA Mats), which has become a great achievement in cleaning polluted water. Unlike traditional water treatment (处理) methods that cost much and use lots of energy, SPA Mats use solar power to grow special algae that eat harmful things in rivers, lakes and even oceans. This technology has been tested in three Chinese cities since early 2026 and shown amazing results.
Each SPA Mat is a thin, flexible sheet that can be spread on water surfaces easily. It is covered with tiny solar panels that provide energy for the algae to grow fast. Every 1 m2 of SPA Mats can clean 120 liters of polluted water per day, and it can work for up to 18 months without being replaced. The team first tested 50 SPA Mats in a small polluted river in Hangzhou. After two months, the water quality improved greatly. Encouraged by this, they added 150 more mats in the same area. In total, these mats reduced harmful chemicals in the river by 65% and made the water clear enough for small fish to return. Local people also noticed that the bad smell from the river was gone, and more birds began to stay nearby.
However, the technology still has room for improvement. The SPA Mats work best in areas with plenty of sunlight, but they don’t work as well on cloudy days or in dark water. Also, making the mats requires special materials that are not cheap yet. Scientists are now working to optimize the technology, hoping to make the mats affordable and suitable for different weather conditions.
The team behind SPA Mats hopes to bring this technology to more countries by 2027, for it shows environmental protection and scientific development can go hand in hand. Such green tech can surely grow fast in the future, solve more water pollution problems around the world and let more people see the great power of science and nature working together.

For more than a month, the world has been excited about a new AI model, DeepSeek-R1. 36 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). 37 That is much less than the hundreds of millions or even billions that US businesses have had to spend on building similar AI models.
38 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, however, used Reinforcement Learning (RL,强化学习) as the core method, Xinhua reported. In RL, AI learns by trying different things. 39 For example, in a game, it gets points for picking up trash (垃圾) and loses points for breaking a glass. Over time, it works out the best solution all by itself.
This is how DeepSeek-R1 has grown to be a reasoning model, which is a new type of AI. 40 Regular (常规的) AI models like GPT-40, however, usually just give direct answers.
A．The new AI was released on Jan 20.
B．It gets rewards for correct actions and gets punished for mistakes.
C．Reasoning models are trained to both think and show the process.
D．DeepSeek-R1’s success largely came from its special training method.
E．It is also the cheapest of its kind and took only about 5.57 million US dollars (40.58 million yuan) to develop.
四、短文填空
根据上下文和所给的首字母写出所缺单词。注意使用正确形式，每空限填一词。
Do you want to become an astronaut It is often considered one of the most challenging j 41 in the world. In fact, being an astronaut is not e 42 because it’s difficult to pass different kinds of training. Just take Wang Yaping, an excellent Chinese astronaut, as an example. She didn’t do well when she took the first training course. However, after years of practice, she finally m 43 to become an astronaut. Now she is so p 44 of her work and shares her space stories with students everywhere. She hopes more young people will learn about space exploration and make their space d 45 come true.

2．句意：这些艰难的时光鼓励他为他的贫穷国家努力学习。
encourage sb. to do sth.是固定搭配，意为“鼓励某人做某事”。to study是动词不定式，符合该搭配的用法。
3．句意：这是非常具有挑战性的，但黄旭华和他的团队勇敢地承担了这个任务。
前半句“This was very challenging.”和后半句“Huang Xuhua and his team took on the task bravely.”之间是转折关系，but是连词，表转折，符合语境。
4．句意：当时，中国缺乏先进的技术和资源，这使得进展就像一场艰难的斗争。
“uphill battle”是泛指“一场艰难的斗争”，“uphill”是以元音音素开头的单词，不定冠词用an。
5．句意：为了保密，他们停止了与外界的联系，甚至是他们的家人。
stop doing sth.意为“停止正在做的事”，stop to do sth.意为“停下来去做另一件事”。此处表示停止与外界联系，contacting是动名词，符合“stop doing sth.”的结构。
6．句意：黄旭华离开家乡很多年。
away from是固定短语，意为“远离”，符合“离开家乡”的语境。故填from。
7．句意：最大的挑战之一是设计一个核反应堆。
“one of+the+形容词最高级+可数名词复数”是固定结构，意为“……中最……之一”。“biggest”是“big”的最高级，前面需加the。
8．句意：因为他们不能从外国专家那里得到帮助，他们不得不依靠自己。
根据“they had to depend on...”可知，他们无法从外国专家那里获得帮助，“couldn’t”是“can’t”的过去式，意为“不能”，符合语境。
9．句意：因为他们不能从外国专家那里得到帮助，他们不得不依靠自己。
“depend on oneself”是固定短语，意为“依靠某人自己”。主语是“they”，反身代词是themselves。
10．句意：另一个具有挑战性的任务是确保潜艇在水下保持平衡。
another意为“另一个”，用于三者或三者以上中的“另一个”，符合语境。others是代词，意为“其他人/物”；the other用于两者中的“另一个”；other是形容词，意为“其他的”，后接名词复数。
11．句意：最后，在20世纪70年代，中国第一艘核潜艇被成功建造和测试。
主语“China’s first nuclear submarine”和谓语“build”之间是被动关系，需用被动语态。根据“in the 1970s”可知，时态为一般过去时，was built符合一般过去时的被动语态结构。
12．句意：黄旭华继续努力工作，直到他去世。
“until”意为“直到……为止”，符合“努力工作到去世”的语境。when意为“当……时”；why意为“为什么”；after意为“在……之后”，与逻辑不符。
13．句意：一天早上，他如此专注于他的设计，以至于他错误地穿了两只不同的鞋去办公室！
“so...that...”是固定结构，意为“如此……以至于……”，此处“deep”是形容词，so符合“so...that...”的结构。
14．句意：一天早上，他如此专注于他的设计，以至于他错误地穿了两只不同的鞋去办公室！
此处需要一个副词来修饰动词“wore”，mistakenly是副词，意为“错误地”，符合语境。mistaken是形容词；mistake是名词或动词；mistakes是“mistake”的复数形式。
15．句意：他们明白他为什么会有这样的行为。
根据前文“He was so deep in thought about his designs that he mistakenly wore two different shoes to the office!”可知，同事们理解他为什么会这样， why引导宾语从句，意为“为什么”，符合语境。how意为“如何”；when意为“什么时候”；what意为“什么”，均与逻辑不符。

For more than a month, the world has been excited about a new AI model, DeepSeek-R1. 36 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). 37 That is much less than the hundreds of millions or even billions that US businesses have had to spend on building similar AI models.
38 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, however, used Reinforcement Learning (RL,强化学习) as the core method, Xinhua reported. In RL, AI learns by trying different things. 39 For example, in a game, it gets points for picking up trash (垃圾) and loses points for breaking a glass. Over time, it works out the best solution all by itself.
This is how DeepSeek-R1 has grown to be a reasoning model, which is a new type of AI. 40 Regular (常规的) AI models like GPT-40, however, usually just give direct answers.
A．The new AI was released on Jan 20.
B．It gets rewards for correct actions and gets punished for mistakes.
C．Reasoning models are trained to both think and show the process.
D．DeepSeek-R1’s success largely came from its special training method.
E．It is also the cheapest of its kind and took only about 5.57 million US dollars (40.58 million yuan) to develop.
【答案】36．A 37．E 38．D 39．B 40．C
【导语】本文讲述了新的人工智能模型DeepSeek-R1在短时间内取得优异成绩，介绍了其开发成本低、采用特殊训练方法等特点，还将其与推理模型和常规AI模型进行对比。
36．前文提到世界对新AI模型DeepSeek-R1感到兴奋，此处需要引出关于它的具体信息，A项“The new AI was released on Jan 20.”给出了该AI模型的发布时间，是对前文的进一步说明，符合语境。
37．前文提到DeepSeek-R1和其他大模型一样擅长处理困难任务但所需算力更少，此处需要补充关于它的其他优势，E项“It is also the cheapest of its kind and took only about 5.57 million US dollars (40.58 million yuan) to develop.”说明了它成本低这一优势，与后文美国企业花费数亿甚至数十亿形成对比，符合语境。
38．后文介绍了传统AI的两种训练方式以及DeepSeek-R1采用的强化学习训练方式，此处需要引出关于训练方法的话题，D项“DeepSeek-R1’s success largely came from its special training method.”引出下文对训练方法的介绍，符合语境。
39．前文提到在强化学习中AI通过尝试不同事物来学习，此处需要进一步说明这种学习方式的特点，B项“It gets rewards for correct actions and gets punished for mistakes.”是对强化学习中AI学习方式的进一步解释，与后文游戏中的例子相呼应，符合语境。
40．前文提到DeepSeek-R1成长为推理模型，此处需要说明推理模型的特点，C项“Reasoning models are trained to both think and show the process.”解释了推理模型的特点，与后文常规AI模型通常只给出直接答案形成对比，符合语境。
