第二节读后续写（满分25分）
Para 1:
After an hour of studying,we realized that we had learned more than we expected.Tom successfully worked out all the math problems that had confused him before,and he even summarized the problem-solving skills by himself.I finished my English composition,and the handwritten words made my thoughts more coherent and sincere.The old man beside us nodded with a smile when he saw our progress.We also helped each other with difficult points—Tom pointed out the grammar mistakes in my composition,and I explained the logical relationships in the math problems to him.The library was quiet,and the sound of turning pages and writing filled our hearts with a sense of achievement.
Para 2:
When the internet came back on,we chose to continue studying with our books and pens.The smart devices around us started to work again,but we didn't feel the urge to use them.We found that studying with traditional tools allowed us to focus more and think deeply.After finishing our study tasks,we chatted with the old man.He told us that technology is a good helper,but it should not replace our own thinking.On our way home,Tom said happily,"Today I learned that even without AI,we can learn well by relying on ourselves and each other."This experience made us understand that the combination of technology and traditional learning methods is the best way to make progress.

Last year, I struggled with English grammar and often felt frustrated before exams. My grades were falling, and I was afraid to ask teachers for help after class. One day, my deskmate introduced me to an AI learning app called GrammarGo.
At first, I was skeptical about whether AI could really help me. But after using it for a week, I was surprised by its effectiveness. The app could analyze my grammar mistakes in my compositions and explain them clearly with examples. It also generated targeted practice exercises for me to strengthen weak points.
Whenever I had a question, I could chat with the AI tutor anytime, and it always gave patient and detailed answers. Gradually, my confidence grew, and I started to enjoy learning English. My grammar improved a lot, and my English score rose from 65 to 88 in the final exam.
This experience taught me that technology can be a powerful helper if we use it wisely. “AI doesn’t replace hard work, but it can make our efforts more efficient,” I told my classmates. Now, I often recommend GrammarGo to my friends who have similar learning problems.

Nowadays, technology has deeply changed our way of life. From AI assistants to smart devices, we enjoy great convenience brought by technology. However, some people worry that over-reliance on technology will make us lose our ability to think and communicate. In my opinion, we should find a balance between using technology and maintaining human connections.
On one hand, technology has greatly improved our efficiency and quality of life. AI tools can help us finish work faster, online learning makes education more accessible, and smart home devices make our life more comfortable. During the pandemic, remote work and online learning allowed us to continue our life without interruption. Technology has become an indispensable part of modern society.
On the other hand, overuse of technology can cause problems. Many people spend too much time on their phones, ignoring face-to-face communication with family and friends. Some students rely too much on AI to finish homework, losing the ability to think independently. Privacy leaks and cyberbullying are also serious problems caused by technology.
Therefore, we should use technology wisely. We should take advantage of its benefits while avoiding its negative effects. We can set limits on screen time, keep in touch with our loved ones offline, and learn to protect our personal data. Only in this way can we enjoy the convenience of technology without losing our humanity.

A. It will make life more convenient

D. We should spend all our time on phones
D
In 2025-2026,artificial intelligence(AI)has stepped into a new stage of practical application,and its integration with green low-carbon development has become one of the most prominent trends in global technological innovation.As the world pays more attention to carbon neutrality and environmental protection,AI technology,with its advantages of big data analysis,intelligent decision-making and efficient optimization,is becoming a core driving force to promote energy conservation,emission reduction and the development of circular economy.
In the field of energy management,AI-powered smart monitoring systems have been widely used in thermal power plants,wind farms and photovoltaic power stations across the world.These systems can collect real-time data on energy production,transmission and consumption through thousands of sensors,and use algorithm models to predict energy demand and adjust output dynamically.For example,in China’s northwest wind power base,AI systems have reduced wind curtailment rate by 18%in 2026 by accurately forecasting wind speed and power grid load,which means more clean energy can be connected to the power grid and used effectively.In urban residential areas,smart energy management apps based on AI can analyze the electricity and water consumption habits of families,and provide personalized energy-saving suggestions,helping ordinary households cut their carbon emissions by an average of 22%per year.
In industrial emission reduction,AI has solved many long-standing problems for traditional high-energy-consuming industries.Intelligent detection robots equipped with AI and machine vision can identify excessive pollutant emissions in factories with higher accuracy and faster speed than manual inspection,and send early warning signals to managers in real time.Some steel and chemical enterprises have introduced AI optimization production lines,which can adjust raw material ratio and production process according to real-time data,reducing energy consumption per unit of product by 15%to 25%while ensuring product quality.What’s more,AI big data platforms are also helping governments to carry out precise environmental supervision—by integrating data from enterprise monitoring,satellite remote sensing and environmental monitoring stations,the platforms can track carbon emission sources in real time and provide scientific basis for formulating emission reduction policies.
Of course,the development of AI-powered green technology still faces some challenges.The high cost of AI equipment and the lack of professional technical talents restrict its popularization in small and medium-sized enterprises.In addition,the operation of AI systems itself also consumes a certain amount of energy,which requires the industry to further develop low-energy-consumption AI chips and optimization algorithms.However,with the continuous investment in scientific research and the improvement of relevant support policies,more and more countries and enterprises are joining the team of AI-enabled low-carbon development.Experts predict that by 2030,AI technology will help the global carbon emission reduction reach more than 1.5 billion tons per year,becoming an indispensable part of the global sustainable development strategy.

第二节 读后续写（满分25分）
Last Saturday, I went to the city library with my little brother Tom to study for the upcoming exam. We planned to use the library’s smart study rooms, which are equipped with AI tutors and high-speed internet. But when we arrived, we found that the internet was down, and all the smart devices were not working. The librarian told us that a sudden power cut had caused the system to crash.
Tom was very upset because he needed to use the AI tutor to practice his math problems. I was also worried because I had to finish my English composition online. We sat down at a table and tried to study without the smart devices, but it was hard to focus. Tom kept complaining, and I felt frustrated too.
Just when we were about to leave, an old man sitting next to us smiled and said, “When I was young, we studied with only books and pens, and we still learned a lot. Maybe you can try to study the old way too.” We looked at him and decided to give it a try. We took out our textbooks and notebooks, and started to study together. Tom asked me questions, and I helped him solve the math problems. I wrote my composition by hand, and it felt more meaningful than typing on a screen.
续写开头：
Para 1: After an hour of studying, we realized that we had learned more than we expected.
Para 2: When the internet came back on, we chose to continue studying with our books and pens.
