What will the future school look like is difficult to make clear, but most experts agree that the school will be electronic in the future.
“Present-day schools will no longer exist in the next century," says a report in The Age. "At that time, future schools will become community-style centers, which run seven days a week, 24 hours a day.” At the same time, computers will surely become a central part of the school in the future.
According to The Age, the distant learning will be popular and students will listen to teachers on computers. Going into classrooms on their computers, students will study at any time, which is very easy for them. However, it is necessary for students to go to the actual school in order to develop some social skills.
The Seashore Primary School is an imaginary school in the future created by the Education Department of Australia. At this school, all the teachers and students have laptop computers. Teachers check messages and call students back on a special telephone system and students use telephones to search for information or speak to their experts who teach their lessons. Besides, all the lessons are related to all sorts of subjects and all the students have their own learning plans created by teachers.
As one headmaster says, a laptop computer is students5 library, data storage （数据存储）as well as the bridge to a wider world. Technology has changed the emphasis of future learning. Thus, well pay more attention to the learning of kids rather than the teaching.
1．According to the report in The Age, students in future schools will _______.
A．have no teachers B．study at a set time
C．mainly study online D．never go to actual school
2．The example of the Seashore Primary School is given to show _______.
A．telephones are important in Australia
B．how future schools will work
C．every student needs a learning plan
D．students enjoy getting in touch with teachers
3．Which of the following is the best title of the text?
A．The Schools in the Future
B．Great Changes in Technology
C．The Seashore Primary School
D．Actual Schools to Be Replaced
【答案】1．C 2．B 3．A
【语篇解读】这是一篇说明文。文章主要谈了对未来学校的构想，例如，现在的学校将不复存在，以后的学校将是电子化的等等。
1．细节理解题。根据第三段中“According to The Age, the distant learning will be popular and students will listen to teachers on computers.”可知根据The Age的报道，远程学习将会很流行，学生将会在电脑上听老师讲课。由此可知，根据The Age的报道，未来学校的学生将主要在网上学习。故选C。
2．推理判断题。根据第四段中“At this school, all the teachers and students have laptop computers. Teachers check messages and call students back on a special telephone system and students use telephones to search for information or speak to their experts who teach their lessons. Besides, all the lessons are related to all sorts of subjects and all the students have their own learning plans created by teachers.”可知在这所学校，所有的老师和学生都有笔记本电脑。老师们通过一个特殊的电话系统检查信息并给学生回电话，学生们用电话搜索信息或与教授他们课程的专家交谈。此外，所有的课程都与各种学科相关，所有的学生都有自己的学习计划，由老师制定。由此可知，这段主要以海滨小学为例，说明了未来学校的工作方式。故选B。
3．主旨大意题。根据文章第一段“What will the future school look like is difficult to make clear, but most experts(专家) agree that the school will be electronic in the future.”可知未来的学校将会是什么样子很难弄清楚，但是大多数专家认为未来的学校将会是电子化的。结合文章主要谈了对未来学校的构想，例如，现在的学校将不复存在，以后的学校将是电子化的等等且本文给出了一篇报告的内容以及海岸小学作为例证。故A选项“未来的学校”符合文章标题。故选A。

【语篇解读】这是一篇说明文。文章主要介绍了瑞典北部的沙雷克国家公园，文章介绍了国家公园内的自然景观和当地居民的情况。
22．考查非谓语动词。句意：在瑞典遥远的北部沙雷克国家公园，我醒来时听到风拍打帐篷布的声音。分析句子结构buffet在句中应用非谓语动词形式，与逻辑主语wind构成主动关系，故应用现在分词作状语。可知故填buffeting。
23．考查冠词。句意：站在山崖边，我看到拉帕河从下面的山谷中流过。结合句意表示“在……的边缘”短语为at the edge of。故填the。
24．考查省略句。句意：沙雷克山曾经被大片的冰层覆盖，现在成了萨米人的家，萨米人是公园的当地居民。在once引导的时间状语从句中，当从句主语和主句主语一致且从句含有be的某种形式时，可省略从句的主语和be，本句的完整形式为：Once Sarek’s mountains were covered by vast sheets of ice，相当于省略了Sarek’s mountains were，故填covered。
25．考查定语从句。句意：沙雷克山曾经被大片的冰层覆盖，现在成了萨米人的家，萨米人是公园的当地居民。此处为非限制性定语从句修饰先行词Sami，先行词在从句中作主语，指人，故应用关系代词who引导，that不能引导非限制性定语从句。故填who。
26．考查动词时态。句意：萨米人以驯鹿为食，和驯鹿一起迁徙，并陪伴驯鹿数百年。根据上文“The Sami lived on reindeer, moved with them, and”可知描述过去发生的事情应用一般过去时。故填accompanied。
27．考查名词的数。句意：今天，大多数萨米人离开了他们在山谷中的古老小屋，转而在沙雷克附近的村庄里过着现代生活。cottage为可数名词，根据上文their可知数量不止一个，应用复数。故填cottages。
28．考查介词。句意：为了保持它的自然状态，除了萨米人，任何人都不允许住在沙雷克，所有新的开发都禁止在公园边界内进行。结合句意表示“除了……”短语为apart from。故填from。
29．考查名词。句意：为了保持它的自然状态，除了萨米人，任何人都不允许住在沙雷克，所有新的开发都禁止在公园边界内进行。空处作主语，表示“开发”应用名词development，表抽象概念，不可数。故填development。
30．考查固定句型。句意：人们希望沙雷克国家公园将永远保持自然而美丽。句型it be hoped that…表“人们希望……”，此处描述客观事实用一般现在时，主语为it，谓语动词用单数。故填is hoped。
31．考查形容词。句意：人们希望沙雷克国家公园将永远保持自然而美丽。remain为系动词，后跟形容词natural作表语。故填natural。

（2022·全国·高考真题）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? That is the very likely future of applying today’s “eyes in the sky” technology to making 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.
Drones are already being used to examine high-tension electrical lines. 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. The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved. Costs would be cut and operations would be more efficient (高效) across the board.
That includes huge savings in maintenance costs and better protection of railway personnel safety. 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. That can be dangerous work that could be avoided with drones assisting the crews’ efforts.
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. To perform these tasks, drones for rail don’t need to be flying overhead. Engineers are now working on a new concept: the rail drones of the future. They will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.
5．What makes the application of drones to rail lines possible?
A．The use of drones in checking on power lines. B．Drones’ ability to work at high altitudes.
C．The reduction of cost in designing drones. D．Drones’ reliable performance in remote areas.
6．What does “maintenance” underlined in paragraph 3 refer to?
A．Personnel safety. B．Assistance from drones.
C．Inspection and repair. D．Construction of infrastructure.
7．What function is expected of the rail drones?
A．To provide early warning. B．To make trains run automatically.
C．To earn profits for the crews. D．To accelerate transportation.
8．Which is the most suitable title for the text?
A．What Faults Can Be Detected with Drones
B．How Production of Drones Can Be Expanded
C．What Difficulty Drone Development Will Face
D．How Drones Will Change the Future of Railways
【答案】5．A 6．C 7．A 8．D
【语篇解读】本文是一篇说明文。应用今天的“空中之眼”的技术，无人机能在保证铁路安全可靠的同时又能帮助铁路运营商每年节省数十亿欧元。
5．推理判断题。根据文章第二段“Drones are already being used to examine high-tension electrical lines. 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.(无人机已经被用于检查高压电线。他们完全可以做同样的事情来检查铁路线路和铁路基础设施的其他重要方面，如铁路轨道和换乘点的正确位置)”可推知，无人机在高空工作的能力使无人机应用于铁路线路成为可能。故选A。
6．词义猜测题。根据后文“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. (据统计，仅欧洲铁路公司每年在铁路维护上的花费就约为200亿欧元，其中包括经常在夜间派遣维修人员检查和维修铁路基础设施)”可知花在maintenance上的费用是用于“inspect and repair the rail infrastructure （检查和维修铁路基础设施”，由此可知“That includes huge savings in maintenance costs and better protection of railway personnel safety”是指大幅节省检修成本和更好地保护铁路人员安全，划线词和 C项：Inspection and repair(检修)含义相近。故选C。
7．推理判断题。根据文章最后一段 “Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.(带有先进传感器和人工智能的非常小的无人机可以像副驾驶一样在火车前面行驶。 凭借他们的预见能力，他们可以发出任何问题的信号，以便快速行驶的火车能够及时做出反应。)”可知对于无人机期待的功能是提前发现问题。故选A。
8．主旨大意题。根据文章主题段第一段“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? That is the very likely future of applying today’s “eyes in the sky” technology to making sure that the millions of kilometers of rail tracks and infrastructure(基础设施)worldwide are safe for trains on a24/7 basis.(一小群无人机能否在保证铁路安全可靠的同时，帮助铁路运营商每年节省数十亿欧元?这很可能是应用今天的“空中之眼”技术的未来，以确保全球数百万公里的铁路轨道和基础设施全天候安全运行。)”以及后文第二段讲到了使用无人机检查电力线路使无人机应用于铁路线路成为可能;第三段讲到了使用无人机大幅节省维护成本和更好地保护铁路人员安全；第四段讲到了通过使用最新的技术，无人机还可以开始为铁路提供更高的价值，可知文章主要讲述了无人机将如何改变铁路的未来，所以D项“无人机将如何改变铁路的未来。”符合文章中心思想，适合作为本文的最佳标题。故选D。
