am，farm manager Dan Wood was at the East Lyme Post Office dropping off a box of fresh produce that later in the day would be delivered by mail to Chelsea Gubbins，who lives across town. 素能提升练 White Gate Farm is a member of Farmers Post，a pilot program that enables smallholder farms across eastern Connecticut to ship fresh produce and other farm products to local households through the United States Postal Service (USPS).Farmers Post takes advantage of a USPS program called Connect Local that allows small businesses to offer same-day and next-day delivery at a fixed low cost. Food remains in the fields because either market prices are too low or the cost of the workforce is too high，or because the size and shape of the produce make it unattractive to stores.Each year，around 10 million tons of crops never get harvested，causing about 16％ of total US food loss and waste. “Food that is wasted has a much larger influence than just the loss of the food itself，” says Julia Kurnik，senior director of Innovation Start-ups at WWF.“Everything that went into growing it goes out the window as well—the water，the land，and the energy.And as the food breaks down，it produces greenhouse gases.The bad effects amplify greatly.” Besides reducing food waste，selling farm products directly to local customers cuts down on the cross-country shipping of food grown in California or elsewhere.This reduces the so-called food miles that researchers believe cause about 6％ of the world's greenhouse gases.Fruits and vegetables，which are often transported out of season and require refrigeration，produce lots of greenhouse gases between farms and people's plates. Wood understands that Farmers Post can help to end that waste.“Farming is kind of like cooking for a big group，” he says.“This is helping us get right on the money，using almost 100％ of what we grow and harvest.” 语篇解读　本文是一篇说明文。文章主要介绍了美国康涅狄格州的一个小型农场 White Gate Farm 通过邮政局的 Connect Local 项目将农产品送给当地居民的故事。 1.Why was Farmers Post started？ A.To create more delivery jobs for local people. B.To provide professional modern farming methods. C.To make the delivery of produce easier and cheaper. D.To pick up and carry customers to different farms. √ 细节理解题。根据第二段内容可知，“农民邮政”项目通过美国邮政服务(USPS)将新鲜农产品和其他农产品运送到当地家庭，该项目允许小企业以固定的低成本提供当日和次日送达服务，使农产品的运输更容易、更便宜。故选C项。 2.What may cause some US crops to remain unharvested according to the text？ A.The shortage of workers and harvesting tool. B.The limited need for farm products. C.Bad weather and road conditions. D.Their low value and poor quality. √ 细节理解题。根据第三段中“Food remains in the fields...make it unattractive to stores.”可知，因为农产品的市场价格低，大小和形状对商店没有吸引力，所以导致美国的很多农作物依旧没有收获就留在地里，故其原因在于它们的价值低和质量差。故选D项。 3.What's the meaning of the underlined word “amplify” in Paragraph 4？ A.Decrease. B.Increase. C.Weaken. D.Change. √ 词义猜测题。根据画线词前面的内容“Everything that went into growing it goes out the window as well—the water，the land，and the energy.And as the food breaks down，it produces greenhouse gases.”可知，浪费食物就意味着种植食物时消耗的水、土地和能源是被浪费的，同时分解食物又产生了温室气体，因此糟糕的影响是在不断增加的。故画线词意为“增强”，与B选项“Increase.”为同义词。故选B项。 4.Which of the following is the best title for the test？ A.A farm-to-table program helps reduce food waste B.The food safety movement has met some challenges C.Small farms play a leading role in serving communities D.Farmers Post explores ways to make high-quality products √ 标题归纳题。根据第二段内容以及倒数第二段中的“Besides reducing food waste，selling farm products directly to local customers cuts down on the cross-country shipping of food grown in California or elsewhere.”并通读全文可知，文章介绍了美国康涅狄格州的一个小型农场 White Gate Farm 通过“农民邮政”项目利用邮政局的 Connect Local项目将农产品送到当地居民的故事。这个项目不仅帮助农场直接销售农产品从而减少了食品浪费，还减少了其他地方运输水果和蔬菜带来的温室气体排放。A选项“A farm-to-table program helps reduce food waste”最适合作文章标题。故选A项。 B (2025·湖北武汉高二期中) Located on the bank of the Yellow River，Zhuangshang village in Yuncheng，Shanxi Province，still has ancient temples and cave dwellings (窑洞)，some of which have a history of more than 800 years. But now，it has received a new label：a “zero-carbon” village，as recognized by the United Nations Development Programme. It starts with a new system.The old caves have been armed with a modern solar power system.The system，developed by Golden Cooperate Information and Automation Technology Co，can provide direct current (DC) power，to the homes of residents，rather than converting between DC and alternating current (AC).It is the key to helping the village achieve carbon neutrality，China Daily reported on August 30. “Residents can directly use electricity that is produced from panels installed on their roofs without buying power from the grid (电力网)，” Chen Wenbo，the company's president，told China Daily.“The system has no effect on the stability of the power grid.It is safe and can improve energy efficiency.” Safe，reliable and green，the low-voltage DC power distribution technology now enables each local household to generate about 4，000 kilowatt hours (千瓦时) of electricity per year.That solves more than 90 percent of the power consumption，according to Yuncheng Daily. “I can save at least 3，000 yuan every year on charges for electricity and fuel，” resident Chen Jiuhong told China Daily.“Plus，without any fire wood or coal in the house，the environment has become cleaner and more comfortable.” “In my house，electrical appliances，such as rice cookers and electric heaters，have replaced traditional gas stoves and coal-fired heating，” said Chen.According to preliminary calculations，each household will reduce carbon dioxide emissions by 7，000 kilograms per year，Yuncheng Daily reported. In dealing with climate change，China aims to peak its carbon dioxide emissions before 2030 and realize carbon neutrality before 2060.According to Chen Wenbo，the solar power system will be widely spread throughout Zhuangshang village.He also hopes the village will be a model for the country's energy revolution. 语篇解读　本文是一篇新闻报道。文章主要报道了山西运城庄上村配备了现代太阳能系统，实现了碳中和。 5.What is essential to the village's carbon neutrality？ A.Switching between DC and AC. B.Buying power from the grid. C.Providing electricity directly from the panels. D.Not influencing the grid's stable state. √ 细节理解题。根据第三段“The system，developed by Golden Cooperate Information...China Daily reported on August 30.”可知，帮助该村实现碳中和的关键是他们使用了直流电。故选C项。 6.Which of the following may be the advantages of the new system？ A.Inexpensive and efficient. B.Appropriate and extraordinary. C.Replaceable and crucial. D.Dependable and eco-friendly. √ 细节理解题。根据第五段内容可知，新的电力系统安全、可靠并且环保。故选D项。 7.According to the passage，how much electricity does each household probably consume annually？ A.3，600. B.4，000. C.4，400. D.5，000. √ 细节理解题。根据第五段内容可知，4 000千瓦时占了90％以上的电力消耗，所以一个家庭总的电力消耗应该是：4 000/90％≈4 444，大约4 400千瓦时。故选C项。 8.Where is the passage likely to come from？ A.A travel journal. B.A book review. C.A biography. D.A news report. √ 文章出处题。根据第三段中的“The system，developed by Golden Cooperate Information...China Daily reported on August 30.”可知，这篇文章应该是来自报纸，是一篇新闻报道。故选D项。 Ⅱ.完形填空(每小题2分，共30分) (2025·江苏一模) 　　When Mysha decided to improve her fitness in late 2019，taking up running was a no-brainer.She lives in a beautiful town on Scotland's east coast，so she found　1　wasn't so bad，with breathtaking scenery.
