原文You’ve heard that plastic is polluting the oceans—between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products. At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam. Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source (来源)of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that' s part of Von Wong's artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear. In a piece from 2018, Von Wong wanted to illustrate (说明) a specific statistic: Every 60 seconds, a truckload's worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped(倾倒)from a truck all at once. Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint. 28. What are Von Wong’s artworks intended for? A. Beautifying the city he lives in. B. Introducing eco-friendly products. C. Drawing public attention to plastic waste. D. Reducing garbage on the beach. 29. Why does the author discuss plastic straws in paragraph 3? A. To show the difficulty of their recycling. B. To explain why they are useful. C. To voice his views on modern art. D. To find a substitute for them. 30. What effect would "Truckload of Plastic" have on viewers? A. Calming. B. Disturbing C Refreshing D. Challenging. 31. Which of the following can be the best title for the text? A. Artists' Opinions on Plastic Safety B. Media Interest in Contemporary Art C. Responsibility Demanded of Big Companies D. Ocean Plastics Transformed into culptures 译文你听说过塑料正在污染海洋——每年有480万至1270万吨塑料进入海洋生态系统。但是，一根塑料吸管或一个塑料杯真的有区别吗？艺术家Benjamin Von Wong想让你知道这是真的。他用塑料垃圾建造了巨大的雕塑，迫使观众重新审视他们与一次性塑料产品的关系。 今年年初，这位艺术家创作了一件名为“Strawpocalypse”的作品，这是一对10英尺高的塑料波浪，在撞击过程中结冰。这座雕塑由从几次志愿者海滩清理中收集的168000根塑料吸管制成，首次出现在越南胡志明市的Estella Place购物中心。 全球只有9%的塑料垃圾被回收。塑料吸管绝不是塑料污染的最大来源，但它们最近受到了抨击，因为大多数人不需要用它们喝水，而且由于它们的体积和重量小，无法回收。冯·王作品中的每一根吸管都可能来自一种饮料，而这种饮料只使用了几分钟。一旦饮料消失，吸管将需要几个世纪才能消失。 在2018年的一篇文章中，冯·王想说明一个具体的统计数据：每60秒，就会有一卡车的塑料进入海洋。在这项名为“卡车塑料”的工作中，Von Wong和一群志愿者收集了10000多块塑料，然后将它们绑在一起，看起来像是从卡车上一次性倾倒的。 Von Wong希望他的工作也能帮助大公司减少塑料足迹。 28.冯的作品是用来做什么的？ A.美化他居住的城市。B.介绍环保产品。 C.提请公众注意塑料垃圾。D.减少海滩上的垃圾。 29.为什么提交人在第3段中讨论塑料吸管？ A.展示回收的困难。B.解释它们为什么有用。 C.表达他对现代艺术的看法。D.找到一个替代品。 30.《塑料卡车》会对观众产生什么影响？ A.冷静。B.干扰C.提神D.挑战。 31.以下哪一个可以是文本的最佳标题？ A.艺术家对塑料安全的看法B.媒体对当代艺术的兴趣 C.大公司的责任要求D.海洋塑料公司被判有罪

1 段译 一小群无人机能否保证铁路的安全性和可靠性，同时帮助铁路运营商每年节省数十亿欧元？这是应用今天的“天空之眼”技术以确保全球数百万公里的铁轨和基础设施全天候安全的未来。

Can a small group of drones (无人机) guarantee the safety and reliability of railways and, at the same time, help railway operators save billions of euros each year? 句译 一小群无人机能否保证铁路的安全性和可靠性，同时帮助铁路运营商每年节省数十亿欧元？ That is the very likely future of applying today's “eyes in the sky” technology to make sure that the millions of kilometres of rail tracks and infrastructure (基础设施) worldwide are safe for trains on a 24/7 basis. 句译 这是应用今天的“天空之眼”技术以确保全球数百万公里的铁轨和基础设施全天候安全的未来。

2 段译 无人机已经被用于检查高压电线。他们可以做同样的事情来检查铁路线和铁路基础设施的其他重要方面，如铁轨和道岔的正确位置。越是定期检查，铁路的安全性、可靠性和准时性就越能得到提高。成本将被削减，运营将全面提高效率。

Drones are already being used to examine high-tension electrical lines. 句译 无人机已经被用于检查高压电线。 They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points. 句译 他们可以做同样的事情来检查铁路线和铁路基础设施的其他重要方面，如铁轨和道岔的正确位置。 The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved. 句译 越是定期检查，铁路的安全性、可靠性和准时性就越能得到提高。 Costs would be cut and operations would be more efficient (高效) across the board.句译 成本将被削减，运营将全面提高效率。

3 段译 这包括大幅节省维护成本和更好地保护铁路人员安全。据计算，仅欧洲铁路每年就花费约200亿欧元用于维护，包括派遣维护人员（通常在夜间）检查和修复铁路基础设施。这可能是一项危险的工作，无人机协助机组人员可以避免这项工作。

That includes huge savings in maintenance costs and better protection of railway personnel safety.句译 这包括大幅节省维护成本和更好地保护铁路人员安全。 It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including sending maintenance staff, often at night, to inspect and repair the rail infrastructure. 句译 据计算，仅欧洲铁路每年就花费约200亿欧元用于维护，包括派遣维护人员（通常在夜间）检查和修复铁路基础设施。 That can be dangerous work that could be avoided with drones assisting the crews' efforts. 句译 这可能是一项危险的工作，无人机协助机组人员可以避免这项工作。

4 段译 通过使用最新技术，无人机还可以开始为铁路提供更高价值的服务，在铁路或道岔出现故障之前检测出故障。为了执行这些任务，铁路无人机不需要在头顶上飞行。工程师们正在研究一个新概念：未来的轨道无人机。它们将在列车前方的轨道上移动，并被编程为自主运行。配备先进传感器和人工智能的超小型无人机可以像副驾驶一样引导列车。凭借他们的预见能力，他们可以发出任何问题的信号，以便快速行驶的列车能够及时做出反应。

By using the latest technologies, drones could also start providing higher-value services for railways, detecting faults in the rail or switches, before they can cause any safety problems.句译 通过使用最新技术，无人机还可以开始为铁路提供更高价值的服务，在铁路或道岔出现故障之前检测出故障。 To perform these tasks, drones for rail don't need to be flying overhead.句译 为了执行这些任务，铁路无人机不需要在头顶上飞行。 Engineers are now working on a new concept: the rail drones of the future. 句译 工程师们正在研究一个新概念：未来的轨道无人机。 They will be moving on the track ahead of the train, and programmed to run autonomously. 句译 它们将在列车前方的轨道上移动，并被编程为自主运行。 Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot.句译 配备先进传感器和人工智能的超小型无人机可以像副驾驶一样引导列车。 With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time. 句译 凭借他们的预见能力，他们可以发出任何问题的信号，以便快速行驶的列车能够及时做出反应。
