But this has raised a big question: who owns the copyright of AI-generated homework? In 2026, a middle school student in Shanghai used an AI tool to write an essay for a national writing competition. The essay won first prize, but later the judges found out that it was written by AI. They took away the prize and said that AI-generated work cannot be considered original. Many teachers agree with this decision. They say that homework is supposed to help students learn and develop their own thinking skills. If students use AI to do their homework, they are not learning anything. They also say that using AI to win competitions is cheating. However, some students have different opinions. They say that AI is just a tool, like a calculator or a dictionary. They use AI to help them organize their ideas and improve their writing. They believe that the final work is still their own because they have to edit and revise the AI-generated content. In my opinion, AI tools are neither good nor bad. It depends on how we use them. If we use them as a helper to improve our learning, they can be very useful. But if we use them to cheat or avoid doing our own work, they will be harmful. Schools should teach students how to use AI properly and responsibly. 1.What happened to the student in Shanghai?（ ） A. He won a writing competition with an AI-written essay. B.

A 【解析】 语篇概述：本文围绕学生使用AI工具完成作业引发的版权争议展开，介绍了老师和学生的不同观点，最后作者表明AI工具本身无好坏之分，关键在于使用方式。 1. 句意：上海的学生发生了什么事？ 考点：细节理解题 解题线索：根据文章第二段“In 2026, a middle school student in Shanghai used an AI tool to write an essay for a national writing competition.

But this has raised a big question: who owns the copyright of AI-generated homework? In 2026, a middle school student in Shanghai used an AI tool to write an essay for a national writing competition. The essay won first prize, but later the judges found out that it was written by AI. They took away the prize and said that AI-generated work cannot be considered original. Many teachers agree with this decision. They say that homework is supposed to help students learn and develop their own thinking skills. If students use AI to do their homework, they are not learning anything. They also say that using AI to win competitions is cheating. However, some students have different opinions. They say that AI is just a tool, like a calculator or a dictionary. They use AI to help them organize their ideas and improve their writing. They believe that the final work is still their own because they have to edit and revise the AI-generated content. In my opinion, AI tools are neither good nor bad. It depends on how we use them. If we use them as a helper to improve our learning, they can be very useful. But if we use them to cheat or avoid doing our own work, they will be harmful. Schools should teach students how to use AI properly and responsibly. 1.What happened to the student in Shanghai?（ ） A. He won a writing competition with an AI-written essay. B.

This is called digital literacy. In 2026, the Chinese government has made digital literacy a compulsory subject in all primary and middle schools.

They learn how to find reliable information online, how to tell the difference between real and fake news, and how to protect their personal information.

They learn to ask questions like: Who made this? Why did they make it? Is it true? This helps them avoid being fooled by fake news and online scams. Digital literacy classes also teach students about the dangers of the Internet. They learn about cyberbullying, online addiction, and the importance of balancing screen time with other activities. Many teachers and parents welcome this new subject. They say that it is necessary for students to learn these skills in order to be safe and successful in the digital world.

In 2026, the live-streaming shopping market is worth more than 5 trillion yuan. However, it also has many problems. One of the biggest problems is false advertising. Many live streamers exaggerate the quality of their products. They use AI-generated pictures and videos to make their products look better than they really are. Some even sell fake products. Another problem is that some live streamers encourage teenagers to spend too much money. They use tricks like "limited time offers" and "flash sales" to make people buy things they don't need.
