【同类练习】(2025·广东省中山市一模 · AI回收机器人)原文呈现(阅读下文,尝试自己划分结构)At a recycling center, two team members spend all day pulling items from a conveyor belt covered in garbage. One pulls out juice cartons and plastic bottles that can be reprocessed, while the other searches for pollutants in the stream of paper products. They are AI-powered robots that each look like a supercharged mechanical arm. Yes, even recycling has gotten involved in the AI revolution.In theory, materials recovery facilities (MRFs) gather the wastes, sort them out, and then sell the materials to companies that can reuse them. In practice, the MRFs aren't all that good. The issue is that it's long been too hard for recycling plants to sort materials with the level of specificity needed to reuse them. The traditional recycling methods succeed in separating waste into broad categories of paper, glass, and metal. But finer layers of detail often go unnoticed, especially with plastic. It's hard for recyclers to determine whether, say, a container is a milk container or a pesticide container.AI stands to make a change, giving recycling plants a far more detailed view into packaging. The AI-powered recycling robots are "vision systems": In the same way ChatGPT is trained, they ingest lots of photographs of thrown-away items in various states of damage. The robots are then able to identify even tiny differences in a product's color, shape, texture, or logo. Recycling operators said that traditional systems tend to be 85 to 95 percent accurate, while robotics companies claim up to 99 percent accuracy.That is not to say that the turn to AI has already fixed recycling. The high-tech systems won't come cheap — an individual robot can cost as much as $300,000. Even if costs eventually decrease, recycling robots can't change the fact that recycling, even at its best, is just not a particularly efficient way of dealing with single-use products. From a plastics-pollution standpoint, what's better than a recyclable single-use cup is not using one at all.题目(请依据结构分析选择答案)1. What is described in the first paragraph? A. A common sight of a recycling center. B. The application of AI tools in recycling. C. The power of AI to change an industry. D. A display of difficulties in waste sorting.2. What is the challenge faced by recycling plants? A. The accuracy of waste sorting. B. The low profit from selling reusable materials. C. The efficiency of waste management. D. The unnoticeable danger in collecting waste materials.3. What does the underlined word "ingest" in Paragraph 3 mean? A. Edit. B. Copy. C. Absorb. D. Download.4. What can be inferred from the last paragraph? A. Single-use products should be restricted. B. Costs of high-tech systems will increase. C. Recyclable products should be advocated. D. AI will be the final frontier of recycling.
(思考提示:先划分本文的 Problem→Solution→Result 结构,再判断每道题对应哪个部分。)
答案详析通读文章后发现文章符合研究报告类说明问结构一: Problem → Solution → Result(问题→解决→结果)即: ├─ 问题:描述一个社会/环境/科技问题 ├─ 解决:介绍研究者提出的新方法/技术/措施 └─ 结果:说明效果、局限性或未来展望文章结构分析如下段落/结构功能/核心内容第1段: 引入现象→ AI机器人已应用于回收行业第2段: 问题→ 回收工厂无法精确分类垃圾第3段: 解决方案→ AI视觉系统可识别细微差异,提高准确率第4段:结果与评价→ AI方案成本高昂,且无法解决根本问题——应减少一次性产品使用结构如何帮助解题:· 问“第一段描述了什么” → 定位第1段(引入现象)· 问“回收工厂面临的挑战” → 定位第2段(问题)· 问“AI如何工作”或“ingest的含义” → 定位第3段(解决方案)· 问“从最后一段能推断出什么” → 定位第4段(结果与评价)· 第1段(Introduction 介绍/ Phenomenon现象) 关键句:“They are AI-powered robots... even recycling has gotten involved in the AI revolution.” 描述回收中心使用AI机器人的场景,引出AI应用于回收这一现象。
· 第2段(Problem 问题) 关键句:“The issue is that it's long been too hard for recycling plants to sort materials with the level of specificity needed to reuse them.” 指出回收工厂面临的难题:无法精确分类,尤其难以区分不同用途的塑料容器。· 第3段(Solution解决方案/法) 关键句:“AI stands to make a change... The robots are then able to identify even tiny differences...” 介绍AI解决方案:AI视觉系统通过学习大量垃圾照片,能识别产品颜色、形状、纹理等微小差异,提高分类准确率。· 第4段(Result 结果& Evaluation评价) 关键句:“The high-tech systems won't come cheap... what's better than a recyclable single-use cup is not using one at all.” 评价AI方案的局限性:成本高昂,且无法从根本上解决一次性产品的问题,真正的解决之道是减少使用一次性产品。
详解:题目与结构的对应关系
1题:What is described in the first paragraph?
回顾这类研究报告结构
第一部分→介绍即引入话题或阐述问题(本段没有阐述问题):描述一个社会/环境/科技问题对应第1段(Introduction介绍)。本段主要介绍AI工具在回收中的应用。 1题:第一段明确说“even recycling has gotten involved in the AI revolution”,描述AI机器人在回收中心工作,因此是AI工具在回收中的应用。故选B。 答案:B(The application of AI tools in recycling)
· 2题:What is the challenge faced by recycling plants?
对应第2段(Problem)。明确指出垃圾分类的精确度是挑战。描述一个社会/科技问题
第二段关键句“The issue is that it's long been too hard for recycling plants to sort materials with the level of specificity needed to reuse them”直接指出挑战是分类精确度。故选A。 答案:A(The accuracy of waste sorting)
· 3题:What does the underlined word "ingest" in Paragraph 3 mean?
对应第3段(Solution解决)。结合语境,指机器人“吸收”或“摄入”大量图片进行学习,与“absorb”同义。第三段说AI机器人“ingest lots of photographs”进行学习,意为“吸收”数据,与absorb相符。故选C。 答案:C(Absorb)
· 4题:What can be inferred from the last paragraph? 对应第4段(Evaluation)。最后一句暗示一次性产品应被限制使用。最后一段最后一句“what's better than a recyclable single-use cup is not using one at all”表明应限制一次性产品。故选A。 答案:A(Single-use products should be restricted)
