The idea for this project came from blocks.Xin Du, a researcher at Southeast University in Nanjing, China, was inspired when a student brought in a set of blocks.Du realized that just like blocks that can be amalgamated together and can be rearranged, water droplets (水滴) could do something similar.This could be a great way to build systems that control the flow of liquids in tiny tubes, a field known as microfluidics, which studies how liquids move in small spaces, such as in batteries or to model blood flow in the body. In their research, Du's team designed a system where water droplets could stick together to form a liquid path.They created a grid with tiny plastic pillars (柱子) that held the droplets in place.When the droplets touched, they joined together but did not spill (溢出) out.This allowed the scientists to control the direction of the liquid path.If they needed to change the direction, they could easily move the droplets around, much like changing the setup of blocks. The system was reconfigurable, meaning it could be quickly adjusted without starting over.This flexibility is important in microfluidics, where experiments often need to be changed as new discoveries are made. Du's team is also working to improve the system by making even smaller channels.Their final goal is to use this technology to improve organoid research, where artificial organs made from living cells are studied.This new system could provide better ways to supply nutrients or blood to these growing cells, making the study of living tissues more accurate and efficient. [语篇解读]本文是一篇说明文。文章主要介绍了一项来自中国的研究团队的创新成果——使用水滴构建的新型设备，该设备有助于微小液体的研究和管理，并强调了其易于构建、调整和改造的特点。 1．How does the device created by the team in China differ from others? A．It is made from plastic.

A．Enlarged. B．Combined. C．Distinguished. D．Shown. 解析：选B。词句猜测题。根据画线单词所在句“Du realized that just like blocks that can be amalgamated together and can be rearranged, water droplets could do something similar.”可推测，积木是可以组合在一起并重新排列。选项B“combined”意为“结合、组合”，与此相符。故选B。 3．What does Du's team expect of the system? A．It will have wide application in medical treatment. B．It will bring a heavy profit to the team. C．It will enable students to be fond of blocks． D．It will decrease the cost of artificial organs． 解析：选A。推理判断题。根据文章最后一段内容可知，他们的最终目标是利用这项技术推动类器官研究的发展，该系统可以为正在生长的细胞提供更好的营养物质或血液供应方式，使对活体组织的研究更加准确和高效，这表明它有望在医疗领域得到广泛应用。故选A。 4．Which is the most suitable title for the text? A．Exposure to Various Blocks Sharpens the Brain B．There Is a Growing Trend Toward Playing Blocks C．Blocks Inspired a New Way to Study Liquids D．Engineers Unlocked the Secret of Water Droplets 解析：选C。标题归纳题。通读全文可知，文章开篇介绍中国团队用水滴制造出新型设备，接着说明该项目的灵感来源于积木，最后提到团队对该系统的改进和期望。C项准确概括了文章核心内容，即积木的拼接和排列方式给研究员带来灵感，促使其设计出用水滴控制液体流动的新方法来研究液体。故选C。 Ⅱ.阅读七选五(每小题2.5分，共12.5分) (2025·广东深圳检测)The history of fireworks began around the first century BC, when the Chinese invented gunpowder (火药).1( ) They used crackers (爆竹) to scare off bad spirits and express good wishes.Early Chinese fireworks were generally firecrackers, designed to make a loud sound.
