(2025·湖南省九校联盟高三下第二次联考)In the race to develop artificial intelligence (AI) systems that can outperform humans, DeepSeek—one cutting­edge technology, developed by a team of researchers in Asia, has already demonstrated its ability to revolutionize industries ranging from healthcare to finance. However, as DeepSeek's capabilities grow, so do the ethical questions surrounding its use.

One of the most impressive features of DeepSeek is its ability to analyze vast amounts of data in real time. For example, in healthcare, it has been used to predict disease outbreaks by analyzing patterns in patient data. In finance, it has helped banks find fraud with very high accuracy. Yet, these advancements come with a price. It raises concerns about privacy and consent (允许). Who owns the data being used, and how can we ensure it is not misused?

Another area where DeepSeek has shown promise is in natural language processing (NLP). Its ability to understand and generate human language has made it a valuable tool for translation services. However, critics argue that this technology could be weaponized to spread misinformation or influence public opinions. The recent controversy over AI­generated deepfake videos is also a reminder of the potential dangers.

Despite these challenges, people who support DeepSeek argue that its benefits far outweigh the risks. They point to its potential to solve some of the world's most pressing problems, such as climate change and poverty. For instance, DeepSeek has been used to make smarter cities consume less energy, reducing carbon emissions significantly. In agriculture, it has helped farmers increase crop yields by analyzing soil data.

The debate about DeepSeek's ethical influences is far from settled. Some call for stricter regulations to prevent misuse, while others believe that innovation should not be stopped because of fear. As we move forward, one thing is clear: the future of AI will depend on our ability to pursue balance between progress and responsibility.

(2025·安徽省合肥市第八中学高三下保温卷)Jill Wheatley was a PE teacher in Germany. On the weekends she competed in marathons around Europe. But life threw her a near deadly blow. While teaching a PE class, she was hit in the head with a baseball. The impact was so great it left her with a brain injury and 70 percent vision loss, permanently blinding her in one eye. She spent 26 months in seven different hospitals, at times wishing it would just all end.

Desperately, Wheatley set out to find comfort and healing in nature. She travelled to Nepal where a friend convinced her to run in the Annapurna 100 with him. The power from that race changed her life and eventually had her looking up at the tops of the mountains. Project Vision 8，000 was born. And she began her mission to stand on top of the world's 14 highest mountains, towering 8，000 metres above sea level, to show herself and others the power in choice and possibility.

Colours, and touch help guide her on the mountain and she has never once felt too tired to carry on. “The only thing constant is change, so when the weather gets really bad or a storm is coming in, I know it is going to pass.” So far, she's had few problems standing among giants, but she admits she continues to struggle with overcoming: the “mountains of her mind”. Having already stared death in the face, Wheatley has great respect for the mountains and the mission she is on. But she's not scared. The experience almost claimed her life, but it is now the driving force and
