But do you know it 　1　 took human beings a very long time to understand numbers this way? That’s why teaching children about numbers is one of the most 　2　 things too. In ancient times when people wanted to count their animals, they had no system of numbers to use. They would put a 　3　 into a bag for each animal. The more animals they owned, the more stones they had. It may 　4　 why the word “calculate” comes from the Latin word “calculus” which means “stone”. Then, people started using lines to count. They would draw a line for each thing they counted, but they still hadn’t 　5　 words for numbers, so they could not write the numbers down. Later on, people used fingers. Again, we have the word that goes back to (追溯) this. The word “digit” comes from the Latin word “digitus” which means “finger”! The ten-finger counting system influenced the 　6　 of our base-10 number system. The number system we use today was first 　7　 in India. It became 　8　 in the Arab countries. Then Arab traders (商人) 　9　 it to Europe. Today, these numbers are 　10　 as Arabic numerals. This system is called the decimal system (十进制) because it uses the number 10 as its base. (  ) 1.

It was developed by DeepSeek, a Chinese company in Hangzhou, Zhejiang Province. The new AI came out on January 20th, 2025. In just one week, it beat other AI models and became the No. 1 free app in the app stores. So far, it has changed the AI world greatly. Its developer said that DeepSeek-R1 is as good at difficult tasks as other AI models. More importantly, it’s the cheapest of its kind, costing only about 5.57 million dollars. That is much cheaper than other similar AI models. DeepSeek-R1’s success largely came from its special training method. 　▲　 One is CoT (思维链), where AI learns to break problems into smaller and simpler steps. The other is SFT (监督微调), which works by showing AI lots of practice problems along with the right answers. Instead of using the traditional ways, DeepSeek mainly uses the method called RL (强化学习). For example, in a clean-up game, it gets points for picking up trash like plastic bottles and loses points for breaking a glass. After some time, it can find the best way to play the game all by itself. What’s more, DeepSeek-R1 is free for everyone to get a copy of its code (代码). They can also change the code when they want to use it for themselves. Being free is important. It helps users share knowledge so that it can be used more widely around the world. (  ) 1. Compared with other AI models, DeepSeek-R1 is ________. A. cheaper to develop B. smarter than others C. better at difficult tasks D. quicker to solve problems (  ) 2. Which of the following can be put in “　▲　” in Paragraph 3? A. It is cool because it is a new kind of AI. B. Traditionally, AI is trained in two ways. C. Let’s see how it is different from others. D. AI engineers can train the models quickly. (  ) 3. What does the underlined word “trash” in Paragraph 4 mean? A. Information. B. Medicine. C. Treasure. D. Rubbish. (  ) 4. Why is it important to use DeepSeek-R1 for free? A. It makes AI safer. B. It creates new knowledge. C. It makes the use of AI wider. D. It creates better companies. (  ) 5. What is the best title for the passage? A. Making an AI Model B. Sharing AI Technology C. Creating AI Robots D. Changing AI World VI. 短文填空 A. They can only use numbers or letters instead. B. Similarly, some numbers hold special meanings in Chinese culture. C. In Western countries, some people think the number 13 brings bad luck. D. It is interesting to see how Chinese people use numbers in different ways. E. To simplify things, they used the hotline number — 10010.com. F. For this reason, many couples choose to get married on May 20th. Do you like the number 13? 1. ________ In the past, a lot of tall buildings didn’t have the 13th floor. 2. ________ For example, the number “4” is said to be unlucky because it sounds like the Chinese word for “death”. But that’s just one example of how numbers carry cultural meanings in China. When I first came to China, I was surprised to see that many websites had numbers instead of letters in their names. I soon realized that this is actually convenient, as Chinese characters cannot be used for website addresses. 3. ________ In pinyin, the telecom company China Unicom is called Zhongguo Liantong. If the company used its pinyin name for its website address, it would be quite long. 4. ________ In addition, the pronunciations of some numbers sound similar to other words in Chinese. This is wordplay (双关语). For example, the numbers “520” in Chinese sound similar to the Chinese phrase “I love you”. 5. ________ VII. 语法填空 Zhao Xintong: His Inspiring Road to the World Snooker Championship On May 5th, 2025, the 28-year-old Chinese snooker star Zhao Xintong won the World Snooker Championship in Sheffield, England, becoming the youngest champion from Asia.
