January 20, 2025, a Chinese tech company named DeepSeek made a new AI called DeepSeek-R1. This smart program can solve math problems, and answer questions quickly, but it costs much less to build. The team spent only 5.58 million. This shows that good ideas can beat big money.
DeepSeek-R1 learns by trying many times and getting better, like how students practice math. Other AIs need lots of prepared examples, but R1 improves by itself. For example, in a global math test, it got 79.8% right, higher than Open AI's model. A simple version of R1 can even run on low-cost computers, helping schools and small companies.
DeepSeek-R1 is free to use and change. On its first day online, over 19, 000 programmers worldwide started projects to study it. A German scientist said experiments with R1 cost 10 instead of 300 with other AIs. Even Meta(a famous US tech company) top scientist said, "This kind of free AI could change the world. "
US tech companies are worried. Meta plans to spend 65 billion more on AI research. Experts(专家) say China is catching up fast. A report in Nature magazine called R1 a "big step forward", proving that smart ideas beat expensive tools.
As a DeepSeek engineer said,"We want AI to be a friend, not something only rich people can use. " With R1, China shows the world that great things come from new ideas and hard work, not just money.
( )1. What is the main purpose of the passage?
A. To compare Chinese and American AI technologies.
B. To introduce a low-cost AI model from China.
C. To explain how computer chips work.
D. To encourage students to become programmers.
( )2. How much did it cost to train DeepSeek-R1?
A. 5.58 million. B. 65 billion. C. 10. D. 300.
( )3. What does the underlined phrase "improves by itself" mean in Paragraph 2?
A. R1 needs lots of prepared examples.
B. R1 becomes better through practice.
C. R1 copies answers from other AIs.
D. R1 only works with expensive tools.

We do eye exercises. We wear sunglasses. We do lots of things to protect our eyes. But we usually forget another important part of our body—the ears. Ears help us hear the world. But many things, such as loud noises, can hurt our ears, even make us deaf. Once this happens, it's hard to get your hearing back. March 3rd is Ear Care Day. So how can we protect our ears?
Keep your ears dry and warm. Dry your ears with a towel(毛巾) after swimming or taking a shower. If you feel water in your ear, shake your head a little bit. This can help you get the water out of your ear. Also, when the sun is shining, wear some sunscreen(防晒霜) on your ears. During the winter, protect your ears with a hat or a scarf.
You should clean your ears. Usually, our ears clean themselves. The earwax(耳垢) builds up, dries out, and then comes out of the ear along with some dirt. Don't clean your ears with anything sharp, or it may make the earwax go too deep into your ears and hurt them. But if your ears start to hurt, you can go to a doctor for help.
It's necessary to use earphones correctly. Don't listen to loud music on your earphones for a long time. Follow the "60 Rule": listen to music for no more than 60 minutes a day. Wearing over-ear(头戴式) earphones is better than wearing in-ear ones. It will do a better job of stopping outside noise. So you can listen at a lower volume.
( )4. Which of the following ways is bad for your ears?
A. Using a towel to dry your ears after swimming.
B. Taking the earwax out with any sharp things.
C. Using some sunscreen on your ears in summer.
D. Covering your ears with a hat or a scarf in winter.
( )5. Which of the following statements is TRUE according to the passage?
A. Our ears can hardly ever clean themselves.
B. We like to do lots of things that may hurt our ears.
C. The earwax may come out of our ears itself.
D. We'd better clean our ears with a doctor's help.
( )6. What does the underlined word "It" in the last paragraph refer to?
A. Following the "60 Rule". B. Listening to loud music.
C. Wearing in-ear earphones. D. Wearing over-ear earphones.
