Unfortunately for the planet，only about 9 percent of that plastic waste has ever been recycled.Another 12 percent has been burned，most recently in waste-to-energy facilities.But most of the rest has gone into landfills—or worse，into the environment. Much of what is done to recover plastic from the waste stream is a purely mechanical process.Once the plastic items have been sorted by polymer type and sent to the recycling workplace，they are simply cut up，washed clean and melted down into pellets (团粒).The pellets are then sold to manufacturers that will incorporate (组合) the material into new products. 　　Many of the chemical recycling techniques are already quite mature. According to a 2019 report by Closed Loop Partners，a New York-based investment firm that invests in circular economy-related start-ups，that list includes more than 40 plastics recycling plants that are either operating or scheduled to open within the next few years in the United States and Canada alone.At least some of those plants are expected to incorporate chemical recycling technology. 　　【语篇解读】　本文是一篇说明文。文章主要介绍了塑料垃圾的产生情况、回收现状以及化学回收技术的发展。 1.When does plastic waste reach its peak？ A.Before 1950.

Inspired by a school project，Sophia conducted in-depth research by interviewing scientists and government officials and presented her findings on water conservation to the United Nations.Sophia’s scientific inquiry led her to experiment with hydrogels (水凝胶)—substances capable of absorbing and retaining water—which could be used in agriculture to reduce water consumption and lessen the strain on the lake’s water supply.While in eighth grade at Rowland Hall Middle School in Salt Lake City，she developed her own eco-friendly hydrogels using starch and other biodegradable materials.Her innovative approach earned her second place in the Technology category at the 2024 Scientific Junior Innovators Challenge，organized by Society for Science. Sophia credits her success to the guidance of her mentors—local high school science teachers who dedicated their time to teaching her organic chemistry，providing resources，and lending her laboratory equipment. “They spent countless lunch hours mentoring me，” she recalls.Sophia emphasizes that finding good mentors can start with something as simple as sending an email to knowledgeable people in the community. One key lesson Sophia learned is that scientific experiments rarely go exactly as planned.Through trial and error，discussions with mentors，and extensive reading，she realized that setbacks are an integral part of the scientific process. For aspiring scientists，Sophia offers advice：observe curiously，think carefully，and act courageously.She encourages a proactive approach to problem-solving，starting with community issues，studying existing solutions，and bravely exploring new paths.Sophia’s experience，marked by overcoming research obstacles，highlights the rewarding nature of scientific exploration.And her story demonstrates that while research can be challenging，the pursuit of solutions is immensely fulfilling. 　　【语篇解读】　本文是一篇记叙文。文章主要讲述了14岁女孩Sophia Zhang致力于环保科研的故事。 4.What is the primary goal of Sophia’s project？ A.Exploring the effects of climate change.

A typical structure contributes approximately one-fifth of its electrical consumption to cooling，as reported by the International Energy Agency.By transferring energy usage to periods of lower cost，major buildings can reduce annual power expenses by hundreds of thousands of dollars.Additionally，this approach minimises reliance on electricity generated by the most polluting fossil fuel power stations. To date，ice-based energy storage has primarily been carried out in offices，hospitals，hotels，and other large facilities with centralised air conditioning，owing to the substantial spatial requirements of the batteries.For instance，a system in the basement of a New-York-City banking high-rise comprises approximately 100 water tanks，each comparable in size to a standard parking space，according to Holly Paeper，president of the American commercial HVAC division at Trane Technologies. Nevertheless，this drawback is gradually being addressed.Nostromo Energy，a manufacturer specializing in ice batteries，has engineered “Ice Brick” units designed for tighter spaces.Meanwhile，California-based Ice Energy has deployed (部署) thousands of its “Ice Bear” systems in single-story locations and intends to introduce a more compact model for residential use later this year. Currently，the expansion of this technology is chiefly restricted by regional climate conditions and pricing strategy.Buildings situated in colder climates may operate cooling systems infrequently.Moreover，if power companies do not apply time-varying electricity rates or offer financial stimulation for demand reduction during peak periods，ice batteries may not deliver significant economic benefits.However，in suitable markets，ice batteries can be integrated with other energy storage technologies to enhance grid (电力网) reliability and meet growing electrical demand. 　　【语篇解读】　本文是一篇说明文。文章介绍了冰电池的工作原理、应用现状与局限性，探讨其如何通过转移用电时间降低成本并减少对污染能源的依赖。 8.What aspect of ice batteries is mainly talked about in Paragraph 1？ A.The cheap source.

B.Low-cost. C.High-powered. D.Well-designed. 词义猜测题。根据第四段内容可知，“compact”是为解决“空间需求大”的问题而设计的，因此“compact”意为“小型的”。故选A。 √ 11.What strategy may promote the application of the ice battery？ A.Increasing funding for power plants. B.Offering off-peak electricity discounts. C.Improving regional climate conditions. D.Banning conventional cooling systems. √ 推理判断题。最后一段中“Moreover，if power companies do not apply time-varying electricity rates or offer financial stimulation for demand reduction during peak periods，ice batteries may not deliver significant economic benefits.”指出，若电力公司不提供“分时电价”或高峰时段节能激励，冰电池难以节省费用，由此可知，非高峰时段电价折扣可促进冰电池的应用。故选B。 D (2026·浙江嘉兴检测) 　　Throughout history，trees have played a crucial role in maintaining ecological balance.They absorb CO2 and transform it into oxygen.But one of the challenges with this traditional carbon absorption is that the CO2 trees store can be released back into the atmosphere when they die. However，the discovery of certain trees in Kenya adds a new dimension to this natural process.These trees，also found in several other countries，have been observed to transform CO2 into calcium oxalate.Then bacteria (细菌) present in the trees and surrounding soil transform it further into calcium carbonate (碳酸钙)，a primary component of limestone and chalk.The unique process ensures that the CO2 is kept in solid form for much longer，even after the tree’s life ends.This finding was emphasized by Mike Rowley from the University of Zurich at the Goldschmidt Conference. While the scientific community is optimistic about these findings，several challenges remain.The primary concern is determining the exact amount of CO2 that these trees can transform throughout their lifetime.Without this accurate data，it is challenging to assess the full impact of this method globally.Understanding the ecological balance and ensuring the preservation of biodiversity are crucial before worldwide planting of these trees.Cooperative research efforts are needed to explore these aspects and develop a comprehensive strategy for using these trees as a natural solution to climate change. This discovery in Kenya invites us to reconsider the potential of natural processes in addressing environmental challenges.While technological solutions to climate change are vital，integrating natural methods offers an alternative approach.The unique ability of these trees presents a promising method for exploration. The journey to fighting climate change is complex.As we dig deeper into understanding natural phenomena like the Kenyan trees，we must ask ourselves：How can we make the best of the power of nature to create a sustainable future for generations to come？ 　　【语篇解读】　本文是一篇说明文。文章聚焦树木生态作用，重点阐述肯尼亚特殊树木将二氧化碳转化为碳酸钙的固碳机制，提及研究挑战，为自然应对气候变化提供新思路。 12.What is special about the trees found in Kenya？ A.They absorb more CO2.
