A team of Chinese scientists aimed to deal with this environmental concern by developing an eco-conscious alternative. In a study published recently in the journal Science Advances, a team at the Institute of Process Engineering of the Chinese Academy of Sciences described how they engineered biodegradable glass made from amino acids (氨基酸). That glass would have a smaller impact on the environment and can break down in a few weeks or in several months. In a test, glass beads (玻璃珠) made out of amino acids were placed under the skin of mice, and the breakdown of the beads and the skin healing process were observed for 30 days. A diagram from the study shows how the mice's bodies broke down the beads. In that month, the glass implant degraded (降解) beneath the skin, the wound site healed, and fur grew back. “Throughout the experimental period, no mice showed any pain-related behavior that may have been caused by the glass implantation, and none of them experienced obvious weight loss，” the researchers wrote in their paper. Although amino acids do degrade over time in the environment, this biodegradable glass is not as durable as traditional glass, because amino acids can break down quickly in heat. In order to overcome this barrier, the researchers chemically modified the amino acids using the heating-cooling procedure applied in glass making. This is when materials for the glass are heated to become soft and then rapidly cooled so as to make the glass tougher. “It's important to point out that this biodegradable glass is currently in the lab stage, and far from large-scale commercialization，” emphasized Yan Xuehai, a professor involved in the study, in a press release. 【解题导语】　本文是一篇说明文。文章介绍了中国科学院的专家团队利用氨基酸研制出一种可降解的环保玻璃。 1．What did the researchers study during the experiment? A.The mice's skin healing process. B．The breakdown of the glass beads. C．The medical value of the new glass. D．The glass degradation with less injury to the mice. D　解析：细节理解题。根据第三段中的“Throughout the experimental period, no mice showed...obvious weight loss”可知，研究人员在实验中研究出玻璃降解对小鼠损伤较小。 2．What does the underlined word “modified” in paragraph 4 mean? A．Transformed.　　　　 B．Melted. C．Enlarged. D．Produced. A　解析：词义猜测题。根据画线词上文“In order to overcome this barrier, the researchers chemically”以及下文“the amino acids using the heating-cooling procedure applied in glass making”可知，为了克服这一障碍，研究人员使用玻璃制造中应用的加热—冷却程序对氨基酸进行化学转换。画线词意为“转换”。 3．How do the researchers improve the durability of amino acid glass? A．Adding more amino acids. B．Heating the glass and rapidly cooling it. C．Using special chemical substances. D．Changing the producing process of glass. B　解析：细节理解题。根据倒数第二段中的“This is when materials for the glass...to make the glass tougher.”可知，研究人员通过加热玻璃并迅速冷却来提高氨基酸玻璃的耐久性。 4．Which of the following can be the best title for the passage? A．A New Kind of Perfect Glass B．Amino Acids Make Glass Tougher C．Large-scale Commercial Glass Products D．Environment-Friendly and Biodegradable Glass D　解析：标题归纳题。通读全文，尤其是根据第一段内容可知，本文主要介绍了中国科学院的专家团队利用氨基酸研制出一种可降解的环保玻璃。因此，D项最适合作为文章的标题。 B (2026·杭州高二期中)On Oct.6, three scientists were awarded the 2025 Nobel Prize in Physiology or Medicine. They discovered how the body stops its own immune system from turning against itself, a process vital for preventing autoimmune (自身免疫性) diseases. The immune system performs a remarkable balancing act. On a daily basis, it must accurately identify and destroy a great many foreign invaders like viruses and bacteria, many of which have gradually developed into what look like our own cells. The critical question was: what system ensures this defense force does not harm the body it is meant to protect? For a long time, the thymus (胸腺), a small organ in the chest, was considered the central area for establishing “immune tolerance”. It was thought to remove attacking cells during early development. However, this theory could not fully explain the body's continuous self-control. The revolutionary change began with the work of Japanese scientist Shimon Sakaguchi. Through a series of innovative experiments on newborn mice in the 1980s and 1990s, he made an unexpected discovery that removing the thymus led to autoimmune disorders, suggesting that the organ was not just removing harmful cells but also the source of specialized protective cells. After a decade of strict investigations, Sakaguchi definitively identified a new class of cells in 1995, which he named “T-reggs”． In the beginning, the scientific community met this discovery with a lot of doubt, since the existence of these “peacekeeper” cells was a completely new idea. The crucial confirmation came from the work of American scientists Mary Brunkow and Fred Ramsdell. Their research in the late 1990s and early 2000s detailed the precise systems: T-reggs either produce calming proteins or deliver direct signals to take control of other attacking immune cells. Furthermore, they identified a specific protein called FoxP3, which acts as a key switch for T-reg function, providing a clear marker for their study. The discoveries of these three scientists have proved that immunity is not merely an attacking force but is under constant, active control. This essential knowledge has opened up new roads for treating autoimmune conditions, improving organ transplant capacity, and even developing more effective cancer treatments, showcasing the significant impact of understanding the body's internal safeguards. 【解题导语】　本文是一篇新闻报道。文章围绕2025年诺贝尔生理学或医学奖展开，介绍了三位科学家的核心发现，且该发现为自身免疫病治疗、器官移植优化及癌症疗法研发开辟了新路径。 5．What does “immune tolerance” in paragraph 3 refer to? A．The process of avoiding self-attack. B．The function in producing immune cells. C．The ability to destroy viruses and bacteria. D.The tendency of losing continuous self-control. A　解析：推理判断题。根据第三段中的“It was thought to remove attacking cells ...body's continuous self-control.”可知，免疫耐受指的是避免自我攻击的过程。 6．What can be inferred from Sakaguchi's experiment? A．The result was immediately accepted. B．The thymus failed to remove harmful cells. C．T-reggs were confirmed to produce calming proteins. D．The thymus had a previously unknown protective function.　 D　解析：推理判断题。根据第四段中的“suggesting that the organ was...the source of specialized protective cells”可知，坂口的实验表明胸腺具有先前未知的保护功能。 7．What is mainly mentioned about the discovery in the last paragraph? A．Its remaining challenges. B．Its impact on our bodies. C．Its wide applications in medicine. D．Its success in curing illnesses. C　解析：推理判断题。根据最后一段内容可推知，该段主要提到了这一发现对医学的广泛应用，包括治疗自身免疫性疾病、提高器官移植能力和开发更有效的癌症治疗方法。 8．Which of the following can be the best title for the passage? A．T-reggs: Body's Peacekeepers B．Thymus: Centre of Creating Cells C．Side Effects of the Immune System D．Fight Against Autoimmune Diseases A　解析：标题归纳题。通读全文可知，文章围绕2025年诺贝尔生理学或医学奖展开，介绍了三位科学家的核心发现：胸腺能产生名为“调节性T细胞(T-reggs)”的保护性细胞，通过特定机制调控免疫系统，避免其攻击自身(即“免疫耐受”)，为多类疾病治疗开辟了新路径。因此，A项最适合作为文章标题。 C In a lab at the University of Miami, containers of coral (珊瑚) from Florida, Honduras, and the Cayman Islands are part of a “coral Olympics”. Scientists are testing which one can best survive hotter ocean temperatures. Over the past two years, 80% of the world's reefs (礁) have faced dangerous levels of heat, which causes coral to bleach (白化). Florida's reefs are on the front line—more than 90% of the living coral has died. For decades, people have tried to restore reefs by growing and planting coral in the ocean. However, after lots of restored coral near Florida died in a recent marine heat wave, scientists began to look for a new strategy. In 2023, ocean temperatures around Florida reached over 90°F, far beyond what branching coral could survive. Bleaching doesn't always kill coral, but long exposure to heat can cut off its nutrient supply. On some reefs, 95% of the restored coral died. These losses pushed researchers to look for new solutions. They shifted their focus to species that survived the heat, such as brain and boulder coral, which grows more slowly but can stand higher temperatures. Meanwhile, scientists began breeding (培育) coral that can better handle heat. Florida coral has been crossbred with coral from Honduras, creating “Flonduran” coral that combines features from both regions. At the University of Miami, researchers are now testing whether the crossbred coral can adapt to warmer waters. Honduran coral comes from reefs that regularly experience higher temperatures, and the hope is that it can pass on its heat adaptability to the next generation. This process, called “assisted gene flow”， helps coral adapt faster. So far, “Flonduran” coral in Florida has shown promise, even under heat stress. However, scientists warn that there is no single “super coral”. Coral strong against heat may be weak against disease. What reefs need most is diversity—many kinds of coral with different strengths. Researchers hope their work can inspire other regions to share coral samples and ideas, giving coral reefs a better chance to survive in a hotter world. 【解题导语】　本文是一篇说明文。文章介绍了科学家为拯救因高温而白化的珊瑚礁，在实验室测试不同地区珊瑚的耐热性，培育新品种，希望为珊瑚礁在更热的世界中提供更好的生存机会。 9．Why were scientists keeping containers of coral in the lab?

B　解析：细节理解题。根据第一段中的“Scientists are testing which one can best survive hotter ocean temperatures.”可知，科学家在实验室保存珊瑚容器是为了检测珊瑚在高温下的生存能力。 10．Why did scientists quit their former coral restoration strategy？　 A．It caused severe coral bleaching. B．The restoration costs were too high. C．It proved ineffective in hot weather. D．The sea near Florida was heavily polluted. C　解析：细节理解题。根据第二段中的“However, after lots of restored coral ... beyond what branching coral could survive.”可知，科学家放弃之前的珊瑚修复策略是因为在高温天气下之前的策略被证明是无效的。 11．What can be inferred about “Flonduran” coral? A.It reproduces faster. B．It may adapt to heat successfully. C．It outgrows native coral. D．It will replace Florida coral soon. B　解析：推理判断题。根据第三段中的“Meanwhile, scientists began breeding coral... from both regions.”以及第四段中的“So far, ‘Flonduran’ coral ...under heat stress.”可推知，它可能会成功地适应高温。 12．What can be a suitable title for the passage? A．The Coral Olympics in Miami Lab B．Saving Coral Through Global Cooperation C．The Coral Bleaching in Florida D．Developing a Better Coral for a Hot World D　解析：标题归纳题。通读全文可知，文章介绍了科学家们为了拯救珊瑚礁，在实验室里测试哪种珊瑚能在高温下生存得最好，并尝试通过杂交培育出更能适应高温的珊瑚品种。因此，D项最适合作为文章标题。 Ⅱ.七选五 (2026·揭阳高二期末)Everyone wants to succeed in their life, don't they?
