Ⅱ. 阅读理解。
Do you have an old mercury thermometer(含汞温度计) in your medicine box at home? For over 100 years, families have used it to check if someone has a fever. It has been a helpful friend to us when we are sick. But things have changed. Now, you are not able to buy it in shops anymore. A new rule took effect. Since 1 January, 2026, companies in China have stopped making mercury thermometers. They also stopped making mercury blood pressure monitors.
You might ask,“Why do we need to stop using them?” The reason is very simple. It is because of the silver liquid inside. This is called mercury. It helps us see the temperature, but it is also very toxic(有毒的). It is dangerous for people and for nature. Imagine you are sick and you feel weak. You might accidentally drop the thermometer on the floor. Smash! It breaks and the mercury comes out.
▲ The mercury can get into the air in your room quickly. If the room is small, the air becomes toxic. This is very bad for everyone in the house, especially for children. Because of this danger, we must make a change. We need something safer for our homes.
Now, electronic thermometers are becoming the new heroes. You have probably seen them before. They are usually made of plastic and have a digital screen. It is true that some people complain about them. They say,“The electronic ones are not accurate. The old ones can tell the temperature more correctly.” It is normal to feel this way when things change. But remember, the most important thing is safety. Electronic thermometers are safe to use, even when you drop them.
This change is good for our environment too. The old “health guards” are retiring. In the future, we will have even better tools. We might use smart watches or other tools to check our health, for example…

【分析】
做这组阅读理解题时，需先通读全文把握主旨，再针对每道题的设问，定位原文对应段落，结合上下文语境、词义及逻辑关系逐一分析选项。具体思路：1. 第1题需明确文章核心内容，判断回答的核心问题；2. 第2题定位第二段，查找停止生产含汞温度计的原因；3. 第3题需结合空格前后的逻辑，选择承上启下的句子；4. 第4题根据上下文对应关系猜测词义；5. 第5题根据最后一句提示推断后续内容。
【解析】
1. 解析：文章先介绍含汞温度计的使用情况，重点阐述中国停止生产含汞温度计的原因，因此文章回答的核心问题是“为什么需要停止生产含汞温度计”，对应选项C。
2. 解析：根据第二段内容，停止生产的原因是温度计内的汞有毒，对人和自然有危险，对应选项C。
3. 解析：空格前讲打碎温度计汞泄漏，空格后讲汞进入空气导致室内空气有毒，空格处需承上启下，说明这个小事故是大问题，对应选项B。
4. 解析：第四段提到“旧的 ones can tell the temperature more correctly”，结合语境，人们抱怨电子温度计不“accurate”，即不“正确的”，对应选项C。
5. 解析：最后一句提到未来会用更好的健康检测工具，比如智能手表，因此接下来会介绍新的检测工具，对应选项C。
