B级 能力素养提升 Ⅳ.阅读理解 (2026甘肃金昌高二下月考) Acid rain,defined as rain,snow,fog or other forms of water that contain high levels of certain strong acids,was first identified by Scottish chemist Robert Augus Smith in 1852.This type of precipitation(降水) typically has a pH between 4.2 and 4.4,while normal rain is slightly acidic with a pH of 5.6.Though natural sources like rotting plants and erupting volcanoes release some acid-forming chemicals,human activities are the main driver of acid rain. Specifically,coal-burning power plants,factories,and cars burn fossil fuels,which send out harmful gases like sulfur dioxide (SO2) and nitrogen oxides (NOx).These gases then react with water,oxygen,and other substances in the air to form acids,and winds can carry these acidic compounds hundreds of miles across the surface. Ecologically,acid rain first makes rivers,lakes,and wetlands more acidic,which in turn causes the soil to release aluminum.This aluminum then flows into water bodies and poisons fish and other water-living creatures,with the harm further spreading through food chains to affect even non-water living animals like birds.Forests also suffer great damage:acid rain not only takes away necessary nutrients such as calcium from the soil and releases aluminum,but also burns tree leaves.As a result,plants become weak in resisting cold,insects,and diseases.Besides ecological damage,acid rain also wears down stone buildings and vehicles;when it turns into breathable fog,it can cause certain health problems. To solve these problems,we need to cut down on fossil fuels used and follow air-quality rules.The United Nations has been promoting global cooperation to reduce harmful gas emissions,and such efforts have helped some ecosystems recover from acid rain damage.However,recovery is slow,and difficulties in unifying global standards make progress harder.As long as fossil fuels continue to be used,acid rain will not disappear—this remains a global challenge that requires ongoing joint efforts. 1.According to the passage,what is the main cause of acid rain? A.Natural sources from erupting volcanoes. B.Human activities like burning fossil fuels. C.The reaction of water with oxygen in the air. D.The spread of acidic compounds by wind. 2.Which of the following is NOT mentioned as a direct consequence of acid rain on forests? A.Taking away essential nutrients from the soil. B.Releasing aluminum that harms plant roots. C.Burning tree leaves and weakening plants. D.Causing birds to lose their habitats. 3.What can be inferred from the passage about the recovery of ecosystems from acid rain damage? A.It is a quick process once harmful gas emissions stop. B.It is fully achieved through the efforts of the UN. C.It faces challenges for lack of unified global standards. D.It is impossible as long as fossil fuels are still in use. 4.What is the author’s attitude towards the issue of acid rain? A.Indifferent. B.Pessimistic. C.Concerned. D.Doubtful. Ⅴ.语篇填空 (2026辽宁沈阳高二下月考) The Mangrove Guardians Along the coast of southern China,a quiet revolution has taken root.Local fishermen,once dependent on offshore fishing,have become 1.　　　　　(protect) of the mangrove forests—ecosystems so vital that scientists call them the “coastal guardians”.  Mangroves,with their complex root systems,serve as natural barriers against storms and rising sea levels.They also provide rich breeding grounds 2.　　　　　 fish and shellfish.Yet for decades,these forests had been destroyed at 3.　　　　　 alarming rate to make way for fish farms and urban development.  In 2018,a conservation program 4.　　　　　　　　　　(launch) with an innovative approach:former fishermen would be trained as eco-tour guides and restoration workers.The idea was simple—if local communities could benefit 5.　　　　　(economic) from protecting mangroves,they would become their most devoted guardians.  Seven years on,the results are striking.With over 2,000 hectares of mangroves 6.　　　　　　(restore) across the region,fish populations have recovered.7.　　　　　 was once a source of conflict has become a model of cooperation.Villagers now earn stable incomes through eco-tourism,8.　　　　　　(show) visitors the forests that they once 9.　　　　　(seek) to clear.  “This is not just about trees,” says project leader Ms.Chen.“It’s about redefining our relationship with nature.We commit ourselves to protecting the mangroves,10.　　　　　 they protect us in return.”  Ⅵ.应用文写作 (2026江西吉安高二下期中) 作为中国文化建设的重要主题活动,文化和自然遗产日(Cultural and Natural Heritage Day)定于每年六月的第二个星期六。在此特殊的日子到来之际,请你写一篇呼吁保护遗产地的文章,给校英文报投稿,内容包括: 1.保护遗产地的重要性; 2.提出具体建议。 注意: 1.写作词数应为80个左右。 2.请按如下格式在相应位置作答。 Protect Our Heritage Sites 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 Ⅶ.读后续写 阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。 (2026云南昭通高二下月考) Emma was a high school student who was passionate about environmental protection.One sunny Saturday,she and her best friend,Lily,decided to go to the local park for a volunteer clean-up.They had heard that the park,once a beautiful natural spot,had been filled with litter due to the large number of visitors during the recent holidays. When they arrived at the park,they were shocked by what they saw.The grass was covered with plastic bottles,food wrappers,and cigarette butts.The lake was filled with floating trash,making it look like a garbage dump.Emma and Lily quickly put on their gloves and took out the trash bags they had brought.They started by picking up the litter on the grass,putting each piece into the bag carefully. As they were working,they noticed a group of kids playing nearby.Some of the kids were throwing empty snack bags on the ground instead of using the trash cans.Emma walked over to them with a friendly smile,“Hey,guys!Do you know that littering is bad for the environment?The park will be much prettier if we all keep it clean.” One of the boys looked at her and said,“But it’s just a small piece of trash.It won’t make a difference.” Just then,a strong wind blew,and a plastic bag flew into the lake.Emma pointed to it and said,“See,that small piece of trash can end up in the water and harm the fish and other animals that live there.” The kids seemed to think about what she said. Suddenly,a park ranger rushed towards them.He looked worried and said,“There’s been an accident!A large barrel of chemical waste has leaked near the park’s water source.We need to stop it from polluting the whole water system!” 注意:1.续写词数应为150个左右; 2.请按如下格式在相应位置作答。 Emma and Lily immediately decided to help. 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 Finally,with their combined efforts,the leak was stopped. 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 知识积累卡 一、重点单词 1.release v.　　　　　　　　　　　  2.specifically adv.　　　　　　　　　　　  3.revolution n.　　　　　　　　　　　　  二、熟词生义 1.level　本文义:n.　　　　　　　  其他义:n.　　　　　　　  2.driver　本文义:n.　　　　　　　　　　  其他义:n.　　　　  三、词块速记 1.wear down 　　　　　　　　　　　  2.cut down on 　　　　　　　  3.serve as 　　　　　　　　　　　  4.benefit from 　　　　　　　　　　  5.commit oneself to 　　　　　　　　　  　 参考答案 Ⅰ.1.swept　2.banned　3.trembled　4.reputation　5.launched Ⅱ.1.charming　2.about　3.precisely　4.thoroughly　5.to Ⅲ.1.to take part in school public welfare activities 2.Nervous but excited 3.not only provides fresh vegetables but also teaches 4.made the shy boy brave enough 5.Hard though he tried Ⅳ.【语篇解读】本文是一篇说明文。文章主要介绍了酸雨的定义、成因、对生态系统和人类社会的危害,以及应对酸雨问题的措施和挑战。 1.B　细节理解题。根据第一段中“Though natural sources like rotting plants and erupting volcanoes release some acid-forming chemicals,human activities are the main driver of acid rain.”以及第二段中“Specifically,coal-burning power plants,factories,and cars burn fossil fuels,which send out harmful gases like sulfur dioxide(SO2) and nitrogen oxides(NOx).”可知,人类活动如燃烧化石燃料是酸雨的主要原因。故选B项。 2.D　细节理解题。根据第三段中“Forests also suffer great damage:acid rain not only takes away necessary nutrients such as calcium from the soil and releases aluminum,but also burns tree leaves.As a result,plants become weak in resisting cold,insects,and diseases.”可知,酸雨对森林的直接影响包括从土壤中带走必要的营养物质、释放铝和灼伤树叶,使植物变得脆弱,而D项“导致鸟类失去栖息地”并未直接提及为酸雨对森林的直接影响。故选D项。 3.C　推理判断题。根据最后一段中“The United Nations has been promoting global cooperation to reduce harmful gas emissions,and such efforts have helped some ecosystems recover from acid rain damage.However,recovery is slow,and difficulties in unifying global standards make progress harder.”可推知,生态系统从酸雨损害中的恢复面临着缺乏统一全球标准的挑战。故选C项。 4.C　推理判断题。根据最后一段中“As long as fossil fuels continue to be used,acid rain will not disappear—this remains a global challenge that requires ongoing joint efforts.”可推知,作者对酸雨问题表现出了担忧的态度,认为这是一个需要全球共同努力解决的持续挑战。故选C项。 Ⅴ.【语篇解读】本文是一篇说明文。文章主要介绍了中国南部沿海渔民从依赖近海捕鱼、破坏红树林,转型为生态守护者,2018 年的保护项目成效显著,实现了人与自然的互利共生。 1.protectors　考查名词复数形式。主语fishermen是复数,此处体现身份的转变——从依赖近海捕鱼的渔民,变成了红树林的保护者,与后文的 guardians形成呼应,所以此处为复数名词protectors。 2.for　考查固定短语。此处为固定搭配provide sth.for sb./sth.,意为“为某人/某物提供某物”,此处指红树林为鱼类和贝类提供了丰富的繁殖地。故填for。 3.an　考查冠词。此处为固定搭配at a/an...rate,意为“以……的速度”;alarming发音以元音音素开头,填不定冠词an。 4.was launched　考查动词时态、语态和主谓一致。时间状语 In 2018 提示用一般过去时;主语a conservation program和 launch是被动关系,用一般过去时的被动语态,主语为单数,故填was launched。 5.economically　考查副词。此处修饰动词 benefit,需要用副词;economic是形容词,副词形式为economically,意为“经济上”。 6.restored　考查with复合结构。分析句子可知,此处为with 复合结构:with+宾语+宾语补足语;宾语mangroves和 restore是被动关系,且动作已完成,用过去分词作宾语补足语。故填restored。 7.What　考查主语从句。空格处引导主语从句,且在从句中作主语,指代“曾经是冲突源头的事物”,用连接代词what引导,句首首字母大写。故填What。 8.showing　考查非谓语动词。句子已有谓语动词 earn,此处用非谓语;主语Villagers 和 show 是主动关系,用现在分词作伴随状语,故填showing。 9.sought　考查动词时态。once 意为“曾经”,描述过去的动作,用一般过去时;seek的过去式为sought。故填sought。 10.and　考查连词。前后两个分句是顺承并列关系:“我们致力于保护红树林,而它们反过来也会保护我们”,故填并列连词and。 Ⅵ.Protect Our Heritage Sites  As Cultural and Natural Heritage Day approaches,it is a good time to focus on heritage protection.Natural heritage sites impress us with their beauty and foster a sense of respect for nature,while cultural ones link us to the past and human history.Preserving them allows us to appreciate the past and gain inspiration for the future. To protect them,we can limit visitors to fragile sites and require advance ticket booking for better management.We also need more investment in heritage restoration.In addition,public education through campaigns and websites is necessary to raise awareness. As their guardians,let’s act together to protect them so that future generations can enjoy these precious gifts of nature and human wisdom. Ⅶ.Emma and Lily immediately decided to help.They first gathered the group of kids,explaining the urgency of the situation.“Every hand counts right now,” Emma said firmly,and the kids nodded,eager to make amends.The ranger handed them protective masks and pointed to the sandbags stored nearby.Together,they carried the heavy sandbags to the leak site,stacking them in a circle around the barrel to contain the spreading chemical waste.Lily used a small shovel to dig a shallow ditch,diverting the small amount of leaked waste away from the water source,while Emma kept watch to ensure no waste seeped through the sandbag barrier.  Finally,with their combined efforts,the leak was stopped.The ranger let out a sigh of relief,patting the kids on the back.“You all did a fantastic job—this could have been a disaster without your help,” he said.The sun was setting as they packed up,and the park looked a little cleaner already.The kids promised to never litter again and even said they’d come back to help with future clean-ups.Emma and Lily walked home tired but happy,knowing that their passion for the environment had not only made a difference that day but also inspired the next generation to care for the planet.  知识积累卡 一、1.释放;排放;放出　2.具体地;明确地;尤其　3.革命;巨变;大变革 二、1.含量;浓度　水平;等级　2.诱因;主要成因　司机 三、1.磨损;侵蚀;消磨　2.削减;减少　3.充当;担任;用作 4.从……中获益　5.致力于;投身于 学科网（北京）股份有限公司 $
