China’s Five-hundred-meter Aperture Spherical Radio Telescope, known as FAST, is carrying out important technical upgrades in Guizhou Province recently. As the world’s largest single-dish radio telescope, it plays a key role in space science research.
Workers are replacing six old steel cables with new home-made parts for the telescope. It is the first time China uses completely independent domestic technology to repair the large equipment. The whole project is planned to finish by the end of June this year.
These new cables will greatly improve the telescope’s safety and working stability. It can receive clearer signals from faraway stars and galaxies in the universe. Better equipment helps scientists discover more unknown space secrets and study black holes and distant stars more accurately.
FAST has made many great scientific achievements since it began working. The latest repair shows China’s rapid progress in space engineering and high-tech equipment. Independent technological development makes China stronger in global astronomical research. It also offers more chances for international scientific cooperation and helps humans know more about the huge universe.

China’s “Artificial Sun” — the Experimental Advanced Superconducting Tokamak (EAST) — has set a new world record, according to the latest report from China Daily. Located in Hefei, Anhui Province, EAST is the world’s first fully superconducting tokamak device, designed to explore clean and nearly limitless nuclear fusion energy.
On January 20, 2025, the EAST team achieved a major breakthrough: maintaining a 100-million-degree Celsius plasma for 1,066 seconds. This is the longest stable operation of high-confinement plasma in tokamak history, far exceeding previous global records. Unlike traditional fossil fuels, nuclear fusion produces no greenhouse gases or long-term radioactive waste, making it a key solution to global energy shortages and climate change.
The success of EAST is the result of over 20 years of hard work by Chinese scientists and engineers. They overcame countless technical challenges in superconducting materials, plasma control and device stability. The project also involves international cooperation, with researchers from over 30 countries contributing to related research.
Looking ahead, EAST will continue to conduct in-depth experiments to optimize fusion technology. Experts believe that nuclear fusion energy could be commercially available within 30 years. As a pioneer in the field, China is leading the global exploration of clean energy and contributing to a sustainable future for humanity.
( ) 1. Where is China’s EAST “Artificial Sun” located
A. In Guiyang, Guizhou.
B. In Hefei, Anhui.
C. In Shanghai, East China.
D. In Beijing, North China.
( ) 2. What can we infer about nuclear fusion energy from Paragraph 2
A. It will replace all energy sources soon.
B. It causes serious pollution like fossil fuels.
C. It is environmentally friendly and sustainable.
D. It has been widely used in daily life.
( ) 3. What does Paragraph 3 mainly imply about the EAST project
A. It relied entirely on foreign technology.
B. Its success came from long-term efforts and teamwork.
C. It faced no difficulties during development.
D. It has no international research value.
( ) 4. What is the main idea of the passage
A. The history of nuclear fusion research worldwide.
B. The advantages of nuclear fusion over fossil fuels.
C. China’s EAST sets a new record and leads clean energy exploration.

China has launched its largest AI for Science (AI4S) computing cluster, a homegrown system designed to accelerate scientific research across key fields like physics, chemistry and biology.
The cluster, developed by the Chinese Academy of Sciences, is equipped with 60,000 advanced AI chips, providing over 10 exaflops of computing power. Unlike traditional supercomputers that focus on general tasks, this AI-centric system is tailored to handle complex scientific calculations, such as simulating molecular structures and analyzing astronomical data. It can cut research time from months to days for many experiments.
The AI4S cluster addresses a critical bottleneck in global scientific research: the slow speed of data processing. By integrating artificial intelligence with high-performance computing, it enables scientists to model complex natural phenomena with higher accuracy.
