C人与自然——沙储暖流
A town in Finland has begun using the world's largest "sand battery(电池)" to help provide heat. The unusual way of storing energy allows the town to create heat when electricity prices are cheap, and store it for long periods of time. The heat can then be used whenever it's needed.
Pornainen is a town mainly heated through a central heating company(公司) called Lovisan Lämpö. Until recently, Pornainen's heat came from burning oil and wood chips. Lovisan Lämpö was looking for ways to cut the pollution it created. They hired(雇用) a company called Polar Night to build the world's largest sand battery. In 2022, Polar Night successfully built a smaller sand battery.
About 43% of Finland's energy comes from renewable sources like solar and wind power. But they only produce power part of the time. This means that sometimes there's more energy than is needed, and sometimes there's not enough. The way to solve this problem is to store the energy so it can be used when it's needed. A sand battery works because sand can be heated to very high temperatures. If well kept, sand can hold this heat for a long time.
Pornainen began using the sand battery earlier this summer to warm up homes, government buildings, a library, and a school. In cold, dark winter months, the battery will cut the amount of wood burned by 60%. Mikko Pajanen, the head of Lovisan Lämpö, says, "Our goal is to stop adding new greenhouse gases to the environment by 2035, and the sand battery is an important step towards that."
Now Polar Night is also looking into ways to turn the stored heat back into electricity.
()23. What can we learn about sand battery?
A. It can create heat whenever it's needed.
B. It was built by Lovisan Lämpö in 2022.

C篇
本文为一篇科技说明文,介绍了芬兰小镇使用“沙电池”存储可再生能源(如太阳能、风能)并用于供暖的创新方式及其环保意义。

【分析】
23题：需定位原文关于沙电池的描述，逐一核对选项。A选项对应原文“create heat when electricity prices are cheap, and store it for long periods of time. The heat can then be used whenever it's needed”，可知是储存后按需使用，而非沙电池随时产热，排除；B选项原文明确建造者是Polar Night，2022年建的是小型沙电池，并非Lovisan Lämpö，排除；C选项结合沙电池的储能功能及Pornainen用其供暖的描述，符合原文；D选项原文提到沙电池可减少污染，排除。
24题：第2段讲Lovisan Lämpö为减污染找方法，雇公司建沙电池；第3段讲芬兰可再生能源供需不稳定，需储能，沙电池可解决该问题，两段均为建沙电池的原因，选A。
25题：定位Mikko的话“the sand battery is an important step towards that（stop adding new greenhouse gases）”，可知他对沙电池的环保作用持积极态度，即充满希望，选B。
26题：文章介绍芬兰小镇用沙电池储能供暖的创新方式及环保意义，核心是介绍新的节能方法，选C。
【解析】
23题：根据原文第一段，沙电池是电价低时产热并储存，需要时使用，并非随时产热，A错误；第二段说明建造者是Polar Night，2022年建的是小型沙电池，B错误；第四段提到Pornainen用沙电池供暖，结合其储能功能，C正确；原文提到沙电池可减少木材燃烧量，污染小，D错误，故选C。
24题：第二段阐述Lovisan Lämpö为减少污染寻找解决方案，雇佣公司建造沙电池；第三段说明芬兰可再生能源供需不稳定，需储能，沙电池可解决该问题，两段均为建造沙电池的原因，故选A。
25题：根据第四段Mikko的表述，沙电池是实现2035年停止新增温室气体目标的重要一步，可知他对沙电池的未来持积极态度，即充满希望，故选B。
26题：文章主要介绍芬兰小镇使用“沙电池”存储可再生能源并用于供暖的创新方式及其环保意义，目的是介绍一种新的节能方法，故选C。
