新素材·禁产水银温度计 ①China stopped making mercury thermometers(水银温度计) completely starting from January 1, 2026. This news has drawn much attention, marking the end of a common household medical tool that has helped families for many years.
②Mercury thermometers have their advantages. They are cheap, often costing only a few yuan, and very accurate(准确的)—their error is only ±0.1℃. This helps people check if they have a fever. Many people also like them because they can be used for a long time if stored carefully. However, their hidden danger can't be ignored. The mercury inside is a harmful heavy metal. It can cause long-term health problems, especially for children's and pregnant women's nervous systems. If the glass breaks, mercury turns into small balls that change into gas quickly. This gas is harmful; it can damage health and pollute the environment for a long time. This ban(禁令) is part of China's efforts to protect the environment.
③ Modern choices, such as electronic thermometers, ear thermometers, and forehead thermometers, are safe and easy to use. They use infrared technology to measure temperature from a distance and give results in seconds. They work well for daily use.
④Some people are buying more mercury thermometers, but it's not necessary. Stores still sell the ones they already have for some time. But if we keep them at home, it may increase the risk of breakage and mercury leakage(泄漏). It's smarter to choose safer thermometers.
⑤Saying goodbye to mercury thermometers is not a loss but progress. This change shows that we are paying more and more attention to health and the environment. Let's welcome these new tools for a safer future.

【语篇解读】本文是一篇说明文。文章主要介绍了中国自2026年1月1日起全面停止生产水银温度计的禁令，分析了水银温度计的优缺点，介绍了替代工具以及该禁令的意义。
1. A 补全文章题。此处位于第三段开头，第二段介绍水银温度计的优缺点，下文介绍现代替代品（电子体温计、耳温计等）的优点，由此可知此处应起承上启下的过渡作用，引出替代品的话题，A项“没有必要担心用什么替代。”回应了人们可能产生的疑虑，自然过渡到下文对安全易用的现代体温计的介绍。故选A。
2. B 推理判断题。根据第二段“However, their hidden danger can't be ignored ...”可知水银温度计存在安全隐患，对健康和环境有害，根据第四段“Some people are buying more mercury thermometers”可知仍有人购买水银温度计，由此可知部分家庭可能并未充分认识到其潜在风险，仍选择继续使用。故选B。
3. B 篇章结构题。结合文章内容可知，第①段引出话题，中国自2026年1月1日起全面停止生产水银温度计；第②③④段分别介绍水银温度计的优缺点、替代品和应对方式；第⑤段总结升华。故选B。
4. D 文章主旨题。结合文章内容可知，本文围绕“中国禁止生产水银温度计”展开，介绍了该禁令的背景、原因、替代工具和意义等。故选D。
