[新素材·脑脊接口技术]A medical breakthrough in China is giving new hope to people with spinal cord(脊髓) injuries. Scientists have created a brain-spinal chip(芯片) that allows paralyzed(瘫痪的) patients to move their legs, and even walk again.
The chip, only 1 mm wide, is designed to be fitted into the brain and spinal cord. If the natural communication between the brain and muscles(肌肉) is lost, this chip becomes the bridge. When the chips work, they create a direct connection between the brain and muscles.
The results have been amazing. A 34-year-old man, paralyzed after a fall, could move his legs just one day after the operation on January 8, 2025. Two weeks later, he walked five meters with help. Three other patients had similar operations in February and March, all getting better within weeks. Even though the patients’ nervous systems were damaged, the chips helped them walk again. This marks a big step in China’s progress in medical science and it brings hope for over 3.7 million people in China.
“This is just the beginning,” Jia, the lead researcher, said. “With the technology, these people may one day leave wheelchairs behind after 3 to 5 years of training.”
Behind this achievement is a long journey of careful research and bold thinking. It took the researchers over 10 years to develop the chip. They tested it on animals first, and then on people. They faced many challenges, yet they never gave up. Step by step, they developed a system to reconnect the mind and body in ways once appearing only in science fiction.
As the chip continues to improve, it lights a new path forward—one built on science, shaped by care, and aimed toward a brighter future.
1. What do we know about the chips mentioned in the passage?
A. They are only as wide as 2 mm. B. They are fitted into the man’s arms.
C. They help the patients walk again. D. They improve the patients’ memory.
2. Which of the following meanings is suitable for the underlined word “bold”?
A. 1. B. 2. C. 3. D. 4.
3. What is the writer’s main reason for writing this passage?
A. To recommend a science story. B. To introduce a new medical success.
C. To compare different treatments. D. To report an experienced doctor in medicine.
4. What is the main idea of this passage?
A. China’s chips bring new hope. B. Science fiction changes our lives.
C. Chinese scientists face challenges. D. China’s medical science has a bright future.

答案
B
【语篇解读】本文是一篇说明文。文章主要介绍了中国科学家研发的脑脊接口技术通过为脑部脊髓植入芯片帮助脊髓损伤患者恢复行走能力，标志着中国在医学科学领域的重大进步，为数百万患者带来新希望。
1. C 细节理解题。根据第一段“Scientists have created a brain - spinal chip that allows paralyzed patients to move their legs, and even walk again.”可知这种芯片可以帮助瘫痪患者重新行走。故选 C。
2. A 词义猜测题。根据语境“Behind this achievement is a long journey of careful research and bold thinking.”可知 bold thinking 与 careful research 是并列关系，描述研究历程。根据下文“It took the researchers over 10 years to develop the chip... they developed a system to reconnect the mind and body in ways once appearing only in science fiction.”可知研究者在十年的研究中面临挑战从未放弃，以突破常规的方式研发新技术，释义 1“敢于冒险和制定困难的决策”与之匹配。故选 A。
3. B 推理判断题。根据第一段“A medical breakthrough in China is giving new hope to people with spinal cord injuries. Scientists have created a brain - spinal chip that allows paralyzed patients to move their legs, and even walk again.”可知本文首段点明主题，即医学上的突破，后续聚焦芯片原理、疗效、研究历程和未来展望。由此可知作者的写作意图是介绍一项新的医疗成果。故选 B。
4. A 文章主旨题。结合文章内容可知，本文主要介绍了中国科学家研发的脑脊接口技术通过为脑部脊髓植入芯片帮助脊髓损伤患者恢复行走能力，为数百万患者带来新希望。故选 A。
