Researchers at the University of Illinois Urbana-Champaign have developed a method to turn food waste into fuel that can power airplanes. Their study, published in Nature Communications, shows this fuel meets all industry standards for regular plane fuel. 1 2 3 4 课 后 习 题 32 This innovation comes at a crucial time. Transportation produces nearly 30% of US greenhouse gas emissions (排放), with commercial flights contributing about 7%. While cars are shifting towards electric batteries, airplanes face a bigger challenge: plane fuel carries about 50 times more energy than standard lithium batteries (锂电池) per kilogram, making long electric flights currently impossible. Biofuels from plants have been used in cars for years, but they haven't worked well for planes because of strict chemical 1 2 3 4 课 后 习 题 requirements. This is where food waste offers a new solution. The Illinois team collected waste from food-processing plants and used a process called hydrothermal liquefaction (HTL)—like a high-tech pressure cooker—to quickly turn it into crude oil (原油). They then cleaned the oil: removing impurities like salt and ash. What remained were the exact hydrocarbons needed for plane fuel. Tests confirmed the fuel passes standards set by aviation authorities without requiring special additives, meaning it could 1 2 3 4 课 后 习 题 theoretically power commercial planes today. “We take the waste and recover energy to make a usable product,” said Professor Yuanhui Zhang, highlighting the shift towards a circular economy. However, expanding the technology from lab experiments to fueling entire planes remains a major problem. It will require significant time, fund, and industrial cooperation. As Zhang notes, “Our research solves the science and engineering problems— then industry can step in.” 1 2 3 4 课 后 习 题 This research not only presents a promising way to reduce plane emissions but also turns a common waste problem into a potential resource for cleaner air travel.#7 【文章大意】本文是一篇说明文，主要介绍研究人员研发出将食物 废料转化为飞机燃料的方法，阐述了其优势、原理及推广难点，凸 显环保价值。 1 2 3 4 课 后 习 题 ( )1.What made standard batteries unsuitable for planes? A.Weight. B.Price. C.Shape. D.Quality. √ 1 2 3 4 课 后 习 题 37 [解析] 细节理解题。根据第二段中的“While cars are shifting towards electric batteries, airplanes face a bigger challenge: plane fuel carries about 50 times more energy than standard lithium batteries (锂电池)per kilogram, making long electric flights currently impossible.”(虽然汽车正转向电池驱动，但飞机面 临着更大的挑战：每公斤飞机燃料的能量约为标准锂电池的50倍， 这使得目前长途电动飞行无法实现。)可知，标准电池因单位重量的 能量过低，不适合飞机使用，核心问题与重量相关。故选A项。 1 2 3 4 课 后 习 题 38 ( )2.What can be inferred about the oil made by the Illinois team? A.It promises huge profits. B.It needs special additives. C.It meets required standards. D.It's made in food-processing plants. √ 1 2 3 4 课 后 习 题 39 [解析] 推理判断题。根据第四段中的“Tests confirmed the fuel passes standards set by aviation authorities without requiring special additives, meaning it could theoretically power commercial planes today.”可推断，伊利诺伊大学团队制成的油 (转化后为燃料)符合所需标准。故选C项。 1 2 3 4 课 后 习 题 40 ( )3.What is the author's attitude towards the technology? A.Supportive. B.Doubtful. C.Indifferent. D.Critical. [解析] 推理判断题。根据最后一段“This research not only presents a promising way to reduce plane emissions but also turns a common waste problem into a potential resource for cleaner air travel.”可知，作者用“有前景的”评价该技术，体现出支持的态度。故 选A项。 √ 1 2 3 4 课 后 习 题 41 ( )4.Which of the following best sums up the text? A.All roads lead to Rome. B.Green outweighs growth. C.Make food out of fuel. D.Turn trash into treasure. [解析] 主旨大意题。通读全文，第一段点明核心“将食物废料转化为 飞机燃料”，后文围绕该技术的原理、优势、难点展开，核心是“变废 为宝”。结合第一段“One person's trash (废弃物) could soon become another person's plane fuel.”(一个人的废弃物可能很快会 变成另一个人的飞机燃料。)可知，“Turn trash into treasure.” (变废为宝。)最能概括全文。故选D项。 √ 1 2 3 4 课 后 习 题 42 Ⅴ 阅读七选五(每小题2.5分，满分12.5分) [2026·广东汕尾高二期末] Encouraging a love for science from an early age sets the foundation for curiosity, critical thinking, and problem-solving skills.
