In a neighborhood, they can significantly reduce the use of motor-vehicles for short-distance trips. For example, instead of driving a car to the nearby grocery store, people can choose a shared bike. This helps to improve air quality in the neighborhood, reduce noise pollution, and contribute to a more sustainable and green living environment.

Fortunately，people are trying different ways of solving those problems.Where will bike-sharing go in China? You decide. “白色自行车”在路上 多年来，阿姆斯特丹的人民一直享受着骑自行车的益处。这源于大约50年前，最初被称为“白色自行车”的想法。阿姆斯特丹是个适合骑行的城市，因为这里地势平坦，所以便于骑行。这里也有很多地方可以停放自行车，市中心的大多数街上都有自行车道。由于方便骑行，阿姆斯特丹非常受骑行者的欢迎——有高达38%的出行是使用自行车。有些人甚至称阿姆斯特丹为“自行车之城”。 译文参考 “白色自行车”的想法从何而来呢？20世纪60年代一群骑行爱好者提出了一个想法。他们认为，如果市中心不允许汽车通行而只允许自行车通行，这会让所有人都受益。他们希望这样能够有助于节约能源，减少污染并提供免费的公共交通。这群人将数百辆自行车涂成白色并放置在阿姆斯特丹的许多地方供人们使用。任何人都能够骑这些自行车做短途出行。人们在行程结束时就地停放自行车，以便其他人能从那儿继续使用。然而不久就出现了问题，“白色自行车”全都消失了——小偷在几周内偷光了所有的自行车！ 1999年，“白色自行车”回到了阿姆斯特丹，这次自行车安装了计算机跟踪系统以记录它们的“一举一动”！要使用自行车，必须插入专用的卡片。新的“白色自行车”实际上不是白色的，而是被涂上了鲜艳的颜色。自行车要停放在专用的停车场。因此，人们要想使用它们，必须将它们停放到目的地附近的另一个专用停车场。 由于这个提议以及众多人的努力，如20世纪60年代的骑行爱好者和那些能够让“白色自行车”回归的人，现在你可以在阿姆斯特丹的市中心享受清新的空气和便利的交通。 如今，“白色自行车”的概念已经在世界范围内广泛传播，全球的共享单车也在增加。 在中国，越来越多的城市拥有了自己的“白色自行车”计划。本地人和游客都喜欢骑共享单车，因为共享单车是一种节省能源、减少空气和噪音污染并使人享受在城市里运动的益处的省钱且简便的方式。然而，问题也随之而来，例如自行车被盗和停放问题。幸运的是，人们正在尝试不同的方法来解决这些问题。在中国，共享单车未来会走向何方？这由你来决定。 返回 语基自查　固根基 返回 阅读单词——识记 1．pedal to the destination　 ______________________ 2．a tracking number 一个______号码 踩着踏板骑行到目的地　 追踪 核心单词——练通 1．_________ into the crowd 消失在人群中 2．a _______ permit 停车许可证 3．a ____ to success 成功之路 disappear　 parking　 path 拓展单词——用活 1．pay _______ fee交停车费 → ____ the car停车 2．_________ from sight从视野中消失 →_____________ of the proof证据的消失 3．________ systems 追踪系统 → _____ his progress追踪他的进步 parking　 park　 disappear　 disappearance　 tracking　 track 重点短语——再现 第一组　汉译英 1．想出，想到　　　　　　　 ____________ 2．发生，出现，走近；被提出 _________ 3．作为……而出名 ____________ 4．为……所喜欢，受……欢迎 ___________________ 第二组　英译汉 5．thanks to ___________ 6．pedal one's way _________ 7．plenty of _______________ come up with　 come up be known as　 become popular with　 幸亏，由于　 骑车前进　 充足的，大量的　 典型句式——默背 1．句型公式　so that引导目的状语从句 教材原句　People would leave the bike in the place where they finished their journey，___________________________________________________ (以便其他人能从那儿继续使用). 2．句型公式　不定式作状语 教材原句　________________(要想骑一辆自行车), you had to put in a special card. 3．句型公式　比较级＋and＋比较级 教材原句　In China，_____________________ (越来越多的城市)have their own “white bike” programmes. 返回 so that someone else could then take it and use it from there　 To take a bicycle　 more and more cities 语基讲练　提能力 返回 归 纳 Ⅰ. 核心词汇练全 come up with 想出，想到   come across　　 偶然遇见；被理解 come out 出现；出版；(花)开放；结果是 come about 发生 come up 发生，出现，走近；被提出 when it comes to (doing) sth 当谈及(做)某事时　 1 ①_________________________(期末考试临近了), so the students are studying hard. ②It is said that _____________________________(他的新书不久就会出版). ③【写作佳句——心理描写】当她突然想出解决这个问题的办法时，她感到如释重负。 ___________________________________________________________________________________________________________she felt a great sense of relief.

Ⅲ.阅读理解(共8小题；每小题2.5分，满分20分) A (2024·甘肃天水高一期中) Being in nature is really good for you.Even just seeing nature on your way to school will brighten your day.This is the experience that is being recreated in Birmingham, England. Once the area around Birmingham was filled with orchards(果园), resulting in its being called“a city surrounded by blossoms (花朵)”．However, by the 1900s, industrialisation had begun to take hold, and the orchards were destroyed to make room for buildings and factories.And according to the National Trust, Birmingham has lost 85% of its trees since the beginning of the 20th century. But on January 17, 2023 that began to change.According to the website Secret Birmingham, a number 11 bus left its station filled with trees instead of people.All along its 27-mile route, the bus dropped off those trees to citizens, schools, and community groups, who then planted them.All in all, about 600 trees have been handed out. “Blossom is not only beautiful, but it's also important for the well-being of the environment，”says Lucy Reid, who's leading the Birmingham project.“It's also great for pollinators(传粉者), such as bees, which help trees produce fruit, and the trees also help to clean the air.” This isn't the first time the National Trust has helped Birmingham blossom. The Trust created“blossoms pop-ups” as part of the Birmingham 2022 Festival. According to the project, blossoming tree installations(装置) were set up in various well-known Birmingham locations such as St.Philip's Cathedral Square. The National Trust has also started blossoming tree projects in other UK cities.In 2021, it created the London Blossom Garden, and now the Trust is planting fruit trees in Plymouth, Newcastle, and Nottingham.Its work is important for the protection of the country's wildlands and climate.However, their Blossoming Birmingham project shows that protecting a country's nature not only helps the environment but brings joy and beauty to people as well. 语篇解读　本文是一篇说明文。文章介绍了英国伯明翰市如何通过植树项目恢复其自然美景的情况。 1．What led to the loss of orchards in Birmingham? A．Extreme climate. B．Poor management. C．City development. D．Decreasing production. √ 细节理解题。根据第二段中的“However, by the 1900s, industrialisation had begun to take hold, and the orchards were destroyed to make room for buildings and factories.”可知，20世纪由于工业化占据主导地位，果园被摧毁为建筑和工厂腾出空间，因此，城市发展导致了伯明翰果园的减少。故选C项。 2．How does the National Trust help Birmingham blossom according to Paragraph 3? A．By filling the buses with blossoms. B．By sending its people to plant trees. C．By providing trees for people to plant. D．By surrounding bus stations with trees. √ 细节理解题。根据第三段中的“...a number 11 bus left its station filled with trees instead of people.All along its 27-mile route, the bus dropped off those trees to citizens, schools, and community groups, who then planted them.”可知，该基金会通过提供树木供人们种植来帮助伯明翰变得漂亮。故选C项。 3．What is Lucy Reid trying to talk about in Paragraph 4? A．The importance of farming. B．The purposes of the project. C．The ways to protect the planet. D．The benefits of flowering trees. 段落大意题。根据第四段内容可知，本段中露西·里德主要介绍开花树木的好处，即具有美观和保护环境的双重益处。故选D项。 √ 4．What does the National Trust contribute to doing according to the last paragraph? A．Beautifying the Earth naturally. B．Bringing nature back to England. C．Improving the living conditions for people. D．Taking the lead in protecting the environment. √ 细节理解题。根据最后一段中的“Its work is important for the protection of the country's wildlands and climate.However, their Blossoming Birmingham project shows that protecting a country's nature not only helps the environment but brings joy and beauty to people as well.”可知，该基金会的工作对保护国家的荒地和气候很重要，它为把大自然带回英国作出了贡献。故选B项。 B We all have an idea about the common types of environmental problems. However, light pollution may be a new term to many of us.But, the fact is that it does affect mankind, other living forms and the environment as a whole. What is light pollution? It presents all forms of misused man-made light. The obvious cause of light pollution is the use of outdoor lighting products improperly.It can be office lighting, car headlights, station lights, streetlights and many more. Light pollution is harmful to both animals and plants.Upon studies, it is found that obvious effects are observed in the behaviour of animals that are active at night.Needless to mention, bright light at night makes it difficult for these animals to hunt, wander and perform their regular activities.Light pollution is directly or indirectly responsible for causing several diseases.Its effects are related to disturbance in the physical rhythm(节奏).It contributes to risks of developing cancerous cells.So, it's nothing less than a threat to human health. You have already seen the negative effects of light pollution on animals and human health.Apart from this, the actual cost of misused light is about millions of dollars every year.It also leads to the release of greenhouse gases and global warming. After all, coal or gas is used for producing electricity. While outdoor lighting and using man-made lighting products are part of our modern lifestyle, some simple ways will surely help in reducing light pollution. For example, while installing(安装)outdoor lighting, make sure that they are pointed downwards.Also, use only the required lighting equipment for both homes and offices.Believe it or not, many people living in the urban areas cannot view clear sky and stars at night.Let's contribute our part in reducing the pollution. 语篇解读　本文为一篇说明文。文章主要介绍了光污染的定义、造成的危害及防治建议等。 5．What can we learn about light pollution? A．It has little effect on plants. B．It contributes to most cancers. C．It is a negative fruit of light technology. D．It affects animals' behavior during the day. √ 细节理解题。根据第二段“The obvious cause of light pollution is the use of outdoor lighting products improperly.”可知，光污染是滥用各种人造光源而形成的，可以说是光技术的不良结果。故选C。 6．Why does light pollution affect the climate? A．It increases the temperature at night. B．It creates clouds in parts of the Earth. C．It stops the release of greenhouse gases. D．It is related to the burning of coal and gas. 细节理解题。根据第四段“It also leads to the release of greenhouse gases and global warming.After all, coal or gas is used for producing electricity.”可知，光需要电，而电是烧煤或煤气产生的。因此，从这个角度来说光污染会引起全球变暖。故选D。 √ 7．What can be inferred from the last paragraph? A．Light pollution needs to be dealt with urgently. B．Only simple ways can help reduce light pollution. C．There is no clear sky or stars over the urban areas. D．Citizens should be banned to install outdoor lighting. √ 推理判断题。根据最后一段最后两句“Believe it or not, many people living in the urban areas cannot view clear sky and stars at night.Let's contribute our part in reducing the pollution.”可知，光污染非常严重，该问题有待紧急解决。故选A。 8．How can we contribute our part in reducing light pollution? A．Forbid the use of outdoor lighting. B．Use clean energy to produce electricity. C．Avoid unnecessary lights at home and offices. D．Reduce money spent on light in urban areas. √ 细节理解题。根据最后一段“Also, use only the required lighting equipment for both homes and offices.”可知，在家里和办公室里只用必需的照明产品便可减少光污染，即避免不必要的照明。故选C。 Ⅳ.完形填空(共15小题；每小题1分，满分15分) I went on a bird-watching hike in the South American rainforest to see some rare birds.Our guide, Carlos, 1 us through the thick trees and plants until we reached a 2 where we could spot the birds we were looking for.We waited 3 , hoping to catch a glimpse of the rare creatures. 4 , Carlos gave us a signal and pointed to a 5 nearby.We could hardly see anything, but Carlos had 6 one of the rare birds we were searching for.
