Carbon dioxide (CO₂) is a main cause of global warming. But now, scientists in China have found a new way to use it. They made a special machine that can use CO₂ to produce electricity. This is a big success in green technology.
This new machine, named "Chaotan One", started working on 20 December 2024 in a steel factory in Guizhou, China. Old power plants use steam to make electricity. But "Chaotan One" is different. It uses a special form of CO₂. It takes the waste heat from the steel factory and turns it into electricity. This solves a long-term bottleneck: in the past, it was hard to use such heat efficiently.
This new technology has two main advantages. First, ▲. It can make over 85% more electricity from the same heat. Second, the machine is simpler. It has fewer parts, so it is easier to use and fix.
This is good news for our planet. It helps factories use their waste heat instead of letting it go. This means they need less other fuel and produce less CO₂. It shows how new ideas can help solve the problem of climate change.
China’s project gives hope. It offers a cleaner way for factories worldwide to make electricity and protect our Earth at the same time.

解析
【分析】
本题是一篇关于中国利用二氧化碳发电的英语阅读理解题，包含细节理解、词义猜测、信息还原、主旨大意类题目。解题思路为：先通读全文把握文章主旨（介绍“超探一号”机器利用CO₂和废热发电的绿色技术）；再针对每个题目，定位原文对应内容，结合上下文语境、选项表述逐一分析排除，选出最匹配的答案。
【解析】
6. 细节理解题：定位到第二段第一句“This new machine, named "Chaotan One", started working on 20 December 2024...”，可知该日期是“超探一号”机器开始运行的日期，对应选项B。
7. 词义猜测题：第二段提到“in the past, it was hard to use such heat efficiently”，说明过去难以高效利用废热是长期存在的难题，故“bottleneck”意为“困难的问题”，对应选项C。
8. 信息还原题：第三段讲新技术的两个优势，空后内容“能从相同热量产生超过85%更多的电”体现了新技术比旧方法效率更高，对应选项B。
9. 细节理解题：定位到第四段“helps factories use their waste heat instead of letting it go. This means they need less other fuel and produce less CO₂”，可知“超探一号”对抗气候变化的原因是将废热转化为电能，减少燃料使用，对应选项B。
10. 主旨大意题：文章主要介绍二氧化碳的新用途（用于发电），对应选项D。
【答案】
