Ⅰ. 阅读下面短文，从每小题所给的A、B、C三个选项中，选出一个最佳选项。
A New Star in the AI World
Recently, people around the world have been talking excitedly about a new AI system named DeepSeek-R1. The company that created it, also called DeepSeek, is from Hangzhou, Zhejiang.
This new AI first came out on January 20. Just one week later, it got ahead of OpenAI’s ChatGPT and became the top free app in the App Store. What makes it so special?
According to the company, DeepSeek-R1 can do difficult tasks like maths as well as other top AI models, but it uses far less computing power (the energy and time computers need to work). It is also much cheaper to build, costing only about 40 million yuan. That is far less than what many US companies spend, which can be hundreds of millions or even billions, said a technology expert(专家).
The secret to its success is a different way of training. Unlike older methods, DeepSeek mainly used Reinforcement Learning (just like how people learn from experience), which lets the AI learn on its own by trying and getting praise or points. This makes it better at thinking through problems.
Also, DeepSeek-R1 is open-source. This means anyone can see and use its code freely, and even change it for their own projects. Being open-source helps share knowledge and make technology better for everyone, said the company’s founder.
