Q1: Imagine what “It” looks like. Q2: Imagine how “It” eats CO2. It Eats CO2 Fast reading It Eats CO2 Carbon dioxide (CO2) is one of Earth’s most common greenhouse gases. It is important for life on the planet. Too much, however, can be very dangerous. In the past 60 years, CO2 in the air has increased 100-200 times faster than it did during the end of the last ice age. This poses a great threat to all the living things on Earth. So, many people and governments are working to solve the problem. One solution is called Carbon Capture and Storage (CCS). This process captures CO2 produced by human activities and stores it underground so it does not go into the air. But this process itself needs energy produced by fossil fuels and costs a lot of money. Also, it faces ongoing questions about the long-term safety of underground CO2 storage. Luckily, there is good news. Researchers at the University of Cambridge have developed a CO2-eating machine. It collects CO2 directly from the air and turns it into useful fuels using sunlight. The machine works in a daily cycle. At night, it captures CO2 from the air using its special filters. When daylight arrives, a mirror on it concentrates the sunlight. The concentrated sunlight heats the CO2 and turns it into a gas called syngas. The syngas can then be turned into fuels. Compared with CCS, the technology is safer, cleaner, and cheaper, making it a game-changer for solving the problem of too much CO2. The researchers are now working on improving the technology. They say that if it can be used at scale, it could kill two birds with one stone: reducing CO2 in the air and creating clean fuels. Where there is waste, there is treasure.

Too much, however, can be very dangerous. 定义核心概念，建立认知起点 转折，引出核心警示 本段开篇明义，从三个层面展开 补充其积极作用，让认知更全面 2 In the past 60 years, CO2 in the air has increased 100-200 times faster than it did during the end of the last ice age. This poses a great threat to all the living things on Earth. So, many people and governments are working to solve the problem. 承接首段风险，提供事实支撑并引出解决方案 自然引出后续解决方案，为下文具体阐述应对措施做铺垫 It has increased 100-200 times faster than it did during the end of the last ice age. It poses a great threat to all the living things on Earth. 用数据强化风险的紧迫性 明确风险的影响范围 Q: How fast has CO₂ increased over 60 years, and what is its influence? 3 One solution is called Carbon Capture and Storage (CCS). This process captures CO2 produced by human activities and stores it underground so it does not go into the air. But this process itself needs energy produced by fossil fuels and costs a lot of money. Also, it faces ongoing questions about the long-term safety of underground CO2 storage. 介绍 CCS 减排方案，同时客观指出其局限性 Choose the disadvantages of CCS. _______ 介绍这一方案的核心原理 CCS的局限 1. High costs 2. Use of fossil fuel energy 3. High requirements for workers 4. Uncertainty about long-term safety 5. Difficulty in capturing CO₂ from the air 1, 2, 4 4 Luckily, there is good news. Researchers at the University of Cambridge have developed a CO2-eating machine. It collects CO2 directly from the air and turns it into useful fuels using sunlight. 转折过渡，给出创新方案 打破前文的消极基调，话题转入新方案 简述原理，为下文详细描述做铺垫 5 The machine works in a daily cycle. At night, it captures CO2 from the air using its special filters. When daylight arrives, a mirror on it concentrates the sunlight.

IT is important for life on the planet. Too much, however, can be very dangerous. In the past sixty years, carbon dioxide in the air has increased one hundred to two hundred times faster than IT did during the end of the last ice age. This poses a great threat to all the living things on earth. So many people and governments are working to solve the problem. One solution is called carbon capture and storage ccs. This process captures carbon dioxide produced by human activities and stores at underground, so IT does not go into the air, but this process itself needs energy produced by fossil fuels and costs a lot of money. Also, IT faces ongoing questions about the long term safety of underground carbon dioxide storage. Lucy, there is good news. Researchers at the university of cambridge have developed a carbon dioxide eating machine. IT collects carbon dioxide directly from the air and turns IT into useful fuels using sunlight. The machine works in a daily cycle at night. IT captures carbon dioxide from the air using its special filters. When daylight arrives, a mirror on IT concentrates the sunlight. The concentrated sunlight heats the carbon dioxide and turns IT into a gas called singers. The thing can then be turned into fuels. Compared with C, C, S, the technology is safer, cleaner and cheaper, making IT a game changer for solving the problem of too much carbon dioxide. The researchers are now working on improving the technology. They say that if IT can be used at scale, IT could kill two birds with one stone, reducing carbon dioxide in the air and creating clean fuels. Where there is waste, there is treasure.
