原文Marian Bechtel sits at West Palm Beach’s Bar Louie counter by herself, quietly reading her e-book as she waits for her salad. What is she reading? None of your business! Lunch is Bechtel’s "me" time. And like more Americans, she’s not alone. A new report found 46 percent of meals are eaten alone in America. More than half（53 percent）have breakfast alone and nearly half（46 percent）have lunch by themselves. Only at dinnertime are we eating together anymore, 74 percent, according to statistics from the report. "I prefer to go out and be out. Alone, but together, you know?" Bechtel said, looking up from her book. Bechtel, who works in downtown West Palm Beach, has lunch with coworkers sometimes, but like many of us, too often works through lunch at her desk. A lunchtime escape allows her to keep a boss from tapping her on the shoulder. She returns to work feeling energized. "Today, I just wanted some time to myself," she said. Just two seats over, Andrew Mazoleny, a local videographer, is finishing his lunch at the bar. He likes that he can sit and check his phone in peace or chat up the barkeeper with whom he's on a first-name basis if he wants to have a little interaction（交流）. "I reflect on how my day's gone and think about the rest of the week," he said. "It's a chance for self-reflection, You return to work recharged and with a plan." That freedom to choose is one reason more people like to eat alone. There was a time when people may have felt awkward about asking for a table for one, but those days are over. Now, we have our smartphones to keep us company at the table. "It doesn't feel as alone as it may have before all the advances in technology," said Laurie Demeritt, whose company provided the statistics for the report. 28. What are the statistics in paragraph 2 about? A. Food variety. B. Eating habits. C. Table manners. D. Restaurant service. 29. Why does Bechtel prefer to go out for lunch? A. To meet with her coworkers. B. To catch up with her work. C. To have some time on her own. D. To collect data for her report. 30. What do we know about Mazoleny? A. He makes videos for the bar. B. He’s fond of the food at the bar. C. He interviews customers at the bar. D. He’s familiar with the barkeeper. 31. What is the text mainly about? A. The trend of having meals alone. B. The importance of self-reflection. C. The stress from working overtime. D. The advantage of wireless technology. 译文Marian Bechtel独自一人坐在西棕榈滩的Bar Louie柜台旁，一边等着吃沙拉，一边静静地读着电子书。她在读什么？不关你的事！午餐是柏克德的“自我”时间。和更多的美国人一样，她并不孤单。 一份新的报告发现，在美国，46%的膳食是单独食用的。超过一半（53%）的人单独吃早餐，近一半（46%）的人自己吃午餐。根据该报告的统计数据，只有在晚饭时间，我们才会一起吃饭，这一比例为74%。 “我更喜欢出去走走。一个人，但要在一起，你知道吗？”柏克特尔从书中抬起头来说。Bechtel在西棕榈滩市中心工作，有时会和同事一起吃午饭，但和我们许多人一样，她经常在办公桌上吃午饭。她可以在午餐时间逃离，以免老板拍她的肩膀。她回到工作岗位时感到精力充沛。“今天，我只是想给自己一些时间，”她说。 就在两个座位上，当地摄像师安德鲁·马佐莱尼正在酒吧吃完午饭。他喜欢坐下来平静地查看手机，或者如果他想与之进行一点互动，可以直接与酒吧老板聊天。“我反思我的一天过得怎么样，并思考本周剩下的时间，”他说。“这是一个自我反思的机会，你带着计划重新投入工作。” 选择的自由是越来越多的人喜欢独自用餐的原因之一。曾经有一段时间，人们可能会因为要一张桌子而感到尴尬，但那些日子已经过去了。现在，我们有了智能手机，可以在谈判桌上陪伴我们。Laurie Demeritt的公司为该报告提供了统计数据，她说：“在技术进步之前，它并不像以前那样孤独。”。 28.第2段中的统计数字是关于什么的？ A.食物种类B.饮食习惯C.餐桌礼仪D.餐厅服务。 29.为什么柏克德更喜欢出去吃午饭？ A.去见她的同事。B.为了赶上她的工作。 C.自己有一些时间。D.为她的报告收集数据。 30.我们对马佐莱尼了解多少？ A.他为酒吧制作视频。B.他喜欢酒吧里的食物。 C.他在酒吧采访顾客。D.和酒吧老板很熟。 31.课文主要讲什么？ A.独自用餐的趋势。B.自我反省的重要性。 C.加班带来的压力。D.无线技术的优势。

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。
