The Rise of Online Learning
In 2024, a report showed that over 500 million people in China had used online learning platforms. This number has grown rapidly over the past five years.
Online learning offers many benefits. First, it is flexible. Students can learn at any time and anywhere. Second, it is often cheaper than traditional classes. Many online courses are free or cost much less. Third, it provides access to top teachers and resources from around the world.
However, online learning also has challenges. Some students find it hard to stay focused without a teacher present. Others miss the social interaction with classmates. A 2025 study found that students who took online courses needed more self-discipline than those in traditional classrooms.
To address these challenges, many platforms have added live classes and discussion forums. Some schools have adopted a blended learning model, combining online and offline teaching.
The future of education is likely to include both online and traditional methods. The key is to find the right balance.
Over 500 million people in China had used online learning platforms by 2024.

How AI Is Changing the Way We Search
When we want to find information online, most of us type keywords into a search engine. But artificial intelligence (AI) is changing this process in exciting new ways.
Traditional search engines work by matching keywords. If you type “best restaurants near me”, the search engine looks for web pages containing those words. This method has worked well for decades, but it has limitations. For example, it cannot understand the meaning behind your words.
AI-powered search engines, like those introduced by major tech companies in 2024 and 2025, work differently. They use large language models to understand the meaning and purpose of your question. If you ask “What should I eat for dinner ”, an AI search engine might consider your past preferences, the weather, and what ingredients you have at home.
These new search tools can also answer complex questions directly. Instead of giving you a list of links, they provide a complete answer. For example, if you ask “How do I change a flat tyre ”, an AI search engine can give you step-by-step instructions with images and videos.
However, AI search engines are not perfect. Sometimes they provide incorrect information. Experts advise users to check important facts from reliable sources. As the technology improves, these problems are expected to become less common.
30. How do traditional search engines mainly work
　A. By understanding the meaning of questions.
　B. By matching keywords in web pages.
　C. By using large language models.
　D. By providing complete answers directly.
31. What can AI-powered search engines do that traditional ones cannot
　A. Search for keywords.
　B. Provide a list of links.
　C. Understand the meaning behind questions.
　D. Work faster than traditional ones.
32. What is one problem with AI search engines according to the passage
　A. They sometimes provide wrong information.　
　B. They are too expensive to use.
　C. They cannot answer simple questions.
　D. They require special training.
33. What is the main idea of this passage
　A. Traditional search engines are no longer useful.
　B. AI search engines are perfect and have no problems.
　C. People should stop using traditional search engines.　
　D. AI is changing how we search for information online.

The Dark Side of Social Media
Social media has changed the way we communicate. Platforms like WeChat, Douyin, and Weibo have billions of users worldwide. They allow us to stay connected with friends, share our lives, and discover new things. But there is a dark side to social media that many people ignore.
One major problem is addiction. A 2025 report found that the average Chinese teenager spends over six hours a day on social media. Some researchers compare this addiction to drug addiction. When users receive likes or comments, their brains release dopamine, a chemical that makes them feel good. This encourages them to keep checking their phones.
Another problem is the spread of false information. False news spreads six times faster than true news on social media. A 2024 study from MIT showed that false stories are 70% more likely to be shared than true ones. This can cause serious problems, especially during emergencies.
Cyberbullying is another serious issue. About 40% of young people have experienced online bullying, according to a 2025 survey. Unlike traditional bullying, cyberbullying can happen at any time. Victims cannot escape even in their own homes.
So what can we do Experts suggest setting time limits for social media use. We should also check information before sharing it. If we see someone being bullied online, we should report it. Social media can be a wonderful tool, but we must use it wisely.
34. How many hours does the average Chinese teenager spend on social media per day
　A. About 2 hours　 B. About 4 hours　 C. About 6 hours　 D. About 8 hours
35. Why do people keep checking their phones according to the passage
　A. Because they have nothing else to do.
　B. Because likes and comments make them feel good.
　C. Because they need to reply to messages.
　D. Because their phones force them to.
36. How much faster does false news spread than true news on social media
　A. Twice as fast　B. Three times as fast　C. Six times as fast　D. Ten times as fast
37. What is the writer‘s main purpose in writing this passage
　A. To encourage people to use more social media.
　B. To compare different social media platforms.　
　C. To explain how social media was invented.
　D. To warn people about the dangers of social media.

China’s Digital Yuan
In 2024, China expanded its digital yuan pilot programme to more cities across the country. By 2025, the digital yuan had been used in over 25 cities, with total transactions exceeding 500 billion yuan. China is leading the world in the development of central bank digital currencies (CBDCs).
What is the digital yuan Unlike cryptocurrencies such as Bitcoin, the digital yuan is issued by the People‘s Bank of China, the country’s central bank. This means its value is stable and backed by the government. People can use it for daily payments through mobile apps, just like WeChat Pay or Alipay.
Why is China promoting the digital yuan First, it makes payments more convenient. No internet connection is needed for some transactions. Second, it helps the government track money flows, which can reduce illegal activities like money laundering. Third, it reduces the cost of printing and handling paper money.
The digital yuan also has benefits for international trade. In 2025, China signed agreements with several countries to use the digital yuan for cross-border payments. This could reduce dependence on the US dollar in global trade.
However, challenges remain. Some people worry about privacy because the government can track transactions. Others prefer using existing payment apps that they are already familiar with. Despite these concerns, the digital yuan is expected to become more widely used in the coming years.
