B 新素材 脑脊髓芯片(2025·苏州中考改编)
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.
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 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, says.
"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.

答案
B 【文章大意】本文介绍了中国科学家研发的一种脑脊髓芯片,它能帮助脊髓损伤患者恢复行走能力。这一成果标志着中国医疗科学的重大进步,为众多患者带来希望。
1. C [解析]细节理解题。根据“Scientists have created abrain-spinal chip(芯片) that allows paralyzed(瘫痪的)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 [解析]词义猜测题。根据“Behind this achievement(成就) is a long journey of careful research and bold thinking.”可知,"bold thinking"与"careful research"为并列关系,描述研究历程。根据词典中的第一条释义“1. PERSON/ACTION not afraid of taking risks and making difficultdecisions”可知,bold意为“敢于冒险和做艰难的决策”,这与研究者十年攻坚、不怕冒险的精神相匹配。故选A。
3. D [解析]写作意图题。根据“A medical breakthrough inChina is giving new hope to people with spinal cord injuries(脊髓损伤). Scientists have created a brain-spinal chip(芯片) that allows paralyzed(瘫痪的) patients to move theirlegs, and even walk again.”可知,文章首段点明主题,即中国在医学上的成功突破,后续聚焦芯片原理、疗效及意义,末段展望未来。因此,作者的写作意图应是介绍一项新的医疗成果。故选D。
4. A [解析]标题归纳题。本文介绍了中国科学家研发的一种脑脊髓芯片是如何帮助脊髓损伤患者恢复行走能力的,标志着中国在医疗领域的重大进步,并为数百万患者带来新希望。选项A“中国芯片带来新的希望”作为标题最合适。故选A。
