But in the past, it faced serious environmental 11 . Many factories produced waste gas into the air and 12 serious air pollution. People had to wear masks (口罩) to keep healthy. The government took many 13 to protect the environment. On the one hand, they strictly 14 the number of highly polluting factories. Some old factories were closed (被关停) 15 . On the other hand, they asked some factories to use new and clean energy sources. They also required some factories to install new equipment (安装新设备) to 16 pollution. They also planted many trees and flowers along the streets. These plants not only made the city look more beautiful but also helped make the air clean. People in Shijiazhuang also played an important 17 in protecting the air. They chose to take the bus, walk or ride bikes to work 18 driving cars. They were 19 of their action because they thought they did their own part for the environment. They also had confidence that the environment in their city would become better 20 they worked together. As more and more people joined in, Shijiazhuang became a greener and cleaner city gradually. 11．A．symbols B．results C．services D．challenges 12．A．caused B．described C．prepared D．realised 13．A．steps B．effects C．purposes D．reasons 14．A．followed B．argued C．controlled D．greeted 15．A．freely B．easily C．usually D．completely 16．A．compare B．reduce C．introduce D．organise 17．A．role B．race C．research D．tie 18．A．according to B．instead of C．such as D．because of 19．A．tired B．careful C．afraid D．proud 20．A．until B．so C．if D．although 【答案】 11．D 12．A 13．A 14．C 15．D 16．B 17．A 18．B 19．D 20．C 【导语】本文讲述石家庄市政府和市民共同努力，通过关闭污染工厂、绿色出行等措施改善环境，使城市变得更绿更清洁。 【详解】11．句意：但在过去，它面临严重的环境挑战。 根据“faced serious environmental”及后文污染描述，可知是面临挑战，challenges“挑战”，契合语境。symbols“象征”，results“结果”，services“服务”，均不符合城市遭遇污染问题的文意。 12．句意：许多工厂向空中排放废气，导致严重空气污染。 根据“produced waste gas”，可知排放废气导致污染，caused表示“造成、引发”，匹配因果逻辑。described“描述”，prepared“准备”，realised“意识到”，无法体现废气与污染的因果关系。 13．句意：政府采取了许多措施保护环境。 固定搭配“take steps”意为“采取措施”，对应后文关停工厂、推广清洁能源等一系列治理行为。 14．句意：他们严格控制高污染工厂的数量。 根据“protect the environment”，可知需控制高污染工厂的数量，controlled“控制”，符合治理污染的行政行为。followed“跟随”，argued“争辩”，greeted“问候”，和环境整治的内容无关。 15．句意：一些旧工厂被完全关停。 根据“closed”及环保力度，可知是完全关停不合格的老旧污染工厂。completely“完全地”，语义通顺合理。freely“自由地”，easily“轻易地”，usually“通常”，不符合关停工厂的治理力度。 16．句意：他们还要求一些工厂安装新设备以减少污染。 根据“protect the environment”，可知目的是减少污染。reduce“减少”，贴合设备的作用。compare“对比”，introduce“介绍、引进”，organise“组织”，不符合设备治理污染的功能。 17．句意：石家庄市民也在保护空气中发挥了重要作用。 固定搭配“play a role in”意为“发挥作用”，用来表述民众参与环保的价值。 18．句意：他们选择乘公交、步行或骑车上班，而不是开车。 乘坐公共交通、绿色出行是用来替代开车的方式，“instead of”表示“代替、而不是”，符合取舍关系。according to“根据”，such as“例如”，because of“由于”，逻辑关系不匹配。 19．句意：他们为自己的行动感到自豪，因为他们认为他们为环境尽了力。 根据“did their own part”，可知人们主动为环保出力，内心会产生自豪感，固定搭配“be proud of”表示“为……”骄傲。tired“疲惫的”，careful“细心的”，afraid“害怕的”，和民众奉献后的心理不符。 20．句意：他们也相信，如果大家齐心协力，他们城市的环境就会变得更好。 大家共同努力是环境改善的前提条件，if“如果”，引导条件状语从句，逻辑通顺。until“直到”，so“因此”，although“虽然”，无法体现条件关系。 三、阅读理解（共5小题，每小题2分，满分10分） Do you know that the average person uses about 150 liters of water every day? That is a lot of water! Most of this water is used for showering, flushing the toilet, washing clothes and dishes, and drinking. But there are many places in the world where people do not have enough clean water. In some African countries, people walk for hours every day just to get a small bucket of water. This water is often dirty and causes diseases. Scientists are working on ways to save water. One idea is to collect rainwater. Rainwater can be used for watering plants and washing cars. Another idea is to clean and reuse wastewater from factories and homes. This is called water recycling. As students, we can also help save water. Turn off the tap while brushing your teeth. Fix dripping taps quickly. Take shorter showers. Every drop counts! Let’s work together to protect our water resources for the future. 21．How much water does an average person use every day? A．About 50 liters. B．About 100 liters. C．About 150 liters. D．About 200 liters. 22．In some African countries, what do people do to get water? A．They collect rainwater. B．They walk for hours. C．They recycle wastewater. D．They buy bottled water. 23．What is water recycling? A．Drinking more water. B．Collecting rainwater. C．Cleaning and reusing wastewater. D．Taking shorter showers. 24．Which of the following is NOT mentioned as a way to save water? A．Turn off the tap while brushing teeth. B．Fix dripping taps. C．Take shorter showers. D．Drink less water. 25．What is the main idea of the passage? A．Water is important and we should save it. B．African people have no water. C．Scientists are not helpful. D．Taking showers is bad. 【答案】21．C 22．B 23．C 24．D 25．A 【导语】本文是一篇说明文，围绕水资源展开，介绍普通人每日用水量、部分地区缺水现状、科学家研发的节水办法以及学生日常节水措施，呼吁大家保护水资源。 【详解】21．第一段写明“Do you know that the average person uses about 150 liters of water every day?”，普通人每天大约使用150升水。 22．第二段提到“In some African countries, people walk for hours every day just to get a small bucket of water.”，说明在一些非洲国家，人们要步行数小时去取水。 23．第三段末尾说明“Another idea is to clean and reuse wastewater from factories and homes. This is called water recycling.”，由此可知水循环就是净化并再利用废水。 24．第四段列举学生节水方法：“Turn off the tap while brushing your teeth. Fix dripping taps quickly. Take shorter showers.”，文中没有提到“少喝水”。 25．全文先介绍日常耗水量、全球缺水困境，再介绍各类节水手段，最后一段号召共同保护水资源，核心主旨是水资源很重要，我们应当节约用水。 1 / 10 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ Unit 1 Water 单元重点单词短语句型语法精练 参考答案 考点夯基攻坚 小题夯基·精准突破 一、根据音标默写单词（共 5 小题，每小题 1 分，共 5 分） 1.drop 2.waste 3.stream 4.duty 5.shortage 二、根据汉语提示填空（共 10 小题，每小题 1 分，共 10 分） 1.polluting 2.treated 3.reduce 4.valuable 5.stored 6.pipes 7.action 8.waste 9.resources 10.tap 三、选词填空（共 10 小题，每小题 1.5 分，满分 15 分） 1.actions 2.pollute 3.value 4.stored 5.reduce 6.waste 7.treat 8.tap 9.resources 10.living 四、用单词的适当形式填空（共 10 小题，每小题 1 分，共 10 分） 1.are polluted 2.valuable 3.action 4.isn’t treated 5.Living 6.to reduce 7.stored 8.shortage 9.is cleaned 10.to protect 五、完成句子（共 5 小题，每小题 2 分，满分 10 分） 1.take action 2.must be treated 3.is valuable for 4.are polluted by 5.turn off 综合攻坚·知能拔高 一、语法选择（共10小题，每小题1分，满分10分） 1．C 2．A 3．B 4．C 5．B 6．C 7．B 8．D 9．B 10．A 二、完形填空（共10小题，每小题1分，满分10分） 11．D 12．A 13．A 14．C 15．D 16．B 17．A 18．B 19．D 20．C 三、阅读理解（共5小题，每小题2分，满分10分） 21．C 22．B 23．C 24．D 25．A 1 / 1 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ Unit 1 Water 单元重点单词短语句型语法精练 教材考点概览 考点夯基攻坚 小题夯基·精准突破 一、根据音标默写单词（共 5 小题，每小题 1 分，共 5 分） 1.
