（2025湖南师大附中高一月考）Taking advantage of people's appetite for trendy clothes, fast fashion has grown rapidly in recent years. It refers to cheaply made clothing that allows consumers to buy a stylish outfit at an affordable price. Today, the fast fashion industry is valued at $150.82 billion （about 1,094 billion yuan）—up 10.74 percent from 2024—and is expected to reach $291.1 billion by 2032, according to UniformMarket.
However, this growth comes with serious environmental consequences, one of which is carbon emissions. To keep costs low, the fast fashion industry uses synthetic（合成的）materials like polyester（聚酯纤维）in the large-scale production of clothing. Polyester can create two to three times more carbon emissions than cotton, leading to serious air pollution. What's worse, the rapid changes in fashion trends have created a “throwaway” culture that results in huge amounts of textile wastes. When synthetic materials end up in landfills, they stay there for hundreds of years, causing
soil damage and polluting groundwater.
In addition to using cheap but harmful materials, fast fashion also reduces costs by taking advantage of its workers. According to the George Washington University, the fast fashion industry employs around 75 million factory workers worldwide, but less than 2 percent earn a living wage. These factors together make fast fashion unsustainable, as it leads to both environmental harm and social injustice.
The need to solve these problems has made sustainable fashion more important than ever. First introduced in the 1990s, this idea refers to clothing that is made ethically（符合道德规范地）and is environmentally friendly. It looks at the whole
life of the product, including how it is made, used and thrown away.
“There is no beauty in the finest cloth if it makes hunger and unhappiness，” said Indian social activist Mahatma Gandhi. His words remind us of the hidden costs behind the fast fashion industry. True beauty lies in clothing that is made ethically, without harming people or the planet.
1.What may the figures used in paragraph 1 highlight ( )
A.The popularity of fashionable clothes. B.The economic benefits of fast fashion.
C.The environmental influence of fast fashion. D.The booming development of the fast fashion industry.
2.Which of the following makes fast fashion unsustainable ( )
A.The diverse dressing styles of people. B.The destruction of soil caused by wastes.
C.The unreasonable use of cotton materials. D.The high costs of employing workers worldwide.
3.What can we know about sustainable fashion ( )
A.It was not proposed until a decade ago.
B.It aims to promote the economic development.
C.It emphasizes the complete process of clothes production.
D.It mainly focuses on the environmental aspect of the clothing industry.
4.What is the best title for the passage ( )
A.Cheap Clothes, High Risks
B.Online Shopping, Fashion Trends
C.Recycling Solves Fashion Waste Crisis
D.Fast Fashion Fuels Global Economic Growth
【解析】 推理判断题。根据题干关键词“figures used in paragraph 1”定位到文章第一段。根据第一段中的“fast fashion has grown rapidly in recent years”和递增的数字“the fast fashion industry is valued at $150.82 billion...reach $291.1 billion by 2032”可知，第一段中所使用的数据可能是为了进一步突出快时尚行业的蓬勃发展。D项是定位内容的概括替换。
【解析】 细节理解题。根据题干关键词“unsustainable”定位到文章第三段。根据第三段开头“In addition to using cheap but harmful materials”可知，第二段也是导致快时尚不可持续的因素，故可在第二、第三段中找答案。根据第二段中的“When synthetic materials...polluting groundwater”可知，废弃物造成的土壤破坏导致了快时尚的不可持续性。B项是“When synthetic materials end up in landfills…polluting groundwater”的概括替换。
【解析】 推理判断题。根据题干关键词“sustainable fashion”定位到文章第四段。根据第四段中的“First introduced in the 1990s, this idea…thrown away”可知，可持续时尚强调了服装生产的整个过程。 C项是定位内容的概括替换。
【解析】 标题判断题。根据第二段中的“However, this growth comes...carbon emissions”和第三段中的“In addition to...taking advantage of its workers”及全文内容可知，文章介绍了快时尚低价背后的环境和社会风险，如空气污染、剥削工人，倡导可持续时尚。因此A项“便宜的服装，高风险”最适合作文章标题。
A Beijing girl surnamed Zhou gave herself a perfect birthday gift in February. The Beijing-based Internet company employee got a 200-yuan cake for half the usual price. The 30-year-old said the cake happened to be her favorite taste and she felt it was the most exceptional find in her year-and-a-half-long buying of “leftover blind boxes”—or randomly（随机地） packed boxes of unsold food and drinks available at discounted rates.
Zhou is one among many middle-aged and young people who are increasingly using WeChat's leftover blind box mini program Xishi Magic Bag, which satisfies consumers' needs while recommending a low-carbon, low-waste lifestyle. After paying online through the program, consumers can collect the randomly packed boxes of leftover food during the appointed time, typically just before closing time, between 8 and 10 pm.
“The original price is generally two to three times the price on the program,” Zhou said, adding that by placing 194 such orders, she ensured that food worth 5,700 yuan, accounting for 520 kilograms in carbon dioxide emissions（二氧化碳排放）, did not go to waste. “I appreciate the environmental idea of the program. In addition, I'm curious and open to trying out different foods and new ways,” she said, adding that she regularly checks for new additions on the program and tries them out.Despite the discounted prices, Zhou said the quality of the service remained good, encouraging her to buy more using the program.
“The program gets along with the development of Internet Plus, in agreement with the idea of sustainable development, and provides a simple way of dealing with food wastage by actively engaging with the public,” said Luo Xueming, chief expert at the Guangdong Modern Urban Industrial Technology Research Institute. However, Luo also stressed food quality and safety problems concerning perishable （易腐坏的） products, and stressed the need to increase consumers' awareness of food resources, which is important for enlarging the user base and ensuring the long-term success of the plan.
“Once widely carried out, this program will hold great importance for China's food safety plan,” he said.#1.5
1.What can we learn about “leftover blind boxes” ( )
A.They're sold to the blind. B.They can be got anytime.
C.They're a widespread lifestyle. D.They can be bought at reduced prices.
2.What does the author want to show by mentioning the numbers in paragraph 3 ( )
A.Zhou has got a cheaper item.
B.Zhou is fond of the program.
C.Much money has been spent on the program.
D.The program is of great benefit to the environment.
3.What is Zhou's attitude towards “leftover blind boxes” ( )
A.Favorable. B.Objective. C.Uncertain. D.Uninterested.
4.According to Luo Xueming, which of the following is the biggest concern ( )
A.Food price. B.Food safety.
C.Environmental protection. D.Sustainable development.
【解析】 细节理解题。根据题干关键词“leftover blind boxes”定位到第一段中的“The 30-year-old said...drinks available at discounted rates”。分析定位句可知，破折号后的“randomly（随机地）packed boxes of unsold food and drinks available at
discounted rates”是对“leftover blind boxes”（剩食盲盒）的解释。由此可知，剩食盲盒可以以折扣价购买。D项中的“at reduced prices”是文中的“at discounted rates”的同义替换。
【解析】 写作目的题。根据题干关键词“the numbers in paragraph 3”定位到第三段中的“by placing 194 such orders... did not go to waste”。由定位句可知，通过下194个这样的订单，她确保了价值5 700元的食物没有浪费，这些食物相当于减少了
520千克的二氧化碳的排放。由此可推知，作者提及这些数字是为了说明这个程序对环境有很大的好处。D项是定位内容的话外音替换。
【解析】 观点态度题。第三段Zhou所说的话“‘I appreciate the environmental idea of the...tries them out”中的appreciate、 open、new、tries them out等都是带有积极感彩的词汇。由此可推知，Zhou对这个项目是支持的（Favorable）态度。objective客观的；uncertain不确定的；uninterested不感兴趣的。
【解析】 细节理解题。根据题干关键词“Luo Xueming”和“the biggest concern”定位到最后一段中的“However, Luo also stressed food quality and safety problems...the long-term success of the plan”。由定位句可知，Luo强调了易腐产品的食品质量和安全问题，并强调需要提高消费者对食品资源的认识。由此可知，食品安全是Luo Xueming最担心的问题。 B项“Food safety”是对定位句中“food quality and safety problems”的同义替换。

【解析】 考查动词的时态和主谓一致。空前是主语The concept，空处为系动词。此处描述客观情况，应用一般现在时。主语是单数概念，谓语动词用单数形式。故填is。
【解析】 考查定语从句。分析句子结构并结合语境可知，“____ she plans to package…rental period”修饰名词短语less formal clothing，且空前有逗号，因此空处引导非限制性定语从句。空处在从句中作package和offer的宾语，先行词less formal
clothing指物，故用关系代词which引导该从句。
【解析】 考查名词所有格。空处作定语，修饰名词lives，应用名词所有格形式。故填people's。
