Drones, as the main tool of low-altitude economy, are widely used in people’s daily life. They are not just toys for fun, but useful helpers in many fields. In the food delivery (配送) field, drones are a big help. Many food delivery companies use drones to send food to people’s homes. Unlike delivery cars, drones don’t need to wait for traffic lights or avoid crowded roads. They can fly directly to the destination (目的地). It usually takes 10 to 20 minutes for a drone to deliver food, which is much faster than traditional delivery ways. This makes people’s life more convenient, especially when they are busy with work or study. In agriculture (农业), drones also play an important role. Farmers used to spray pesticide by hand, which was tiring and inefficient (低效的). Now, with drones, farmers can finish spraying a large field in a short time. Drones can spray pesticide evenly (均匀地), which helps crops grow better. What’s more, using drones is safer for farmers, because they don’t need to get close to harmful pesticide. Besides, drones are used in environmental protection. Some drones are equipped with (配备) special cameras and sensors (传感器). They can fly over rivers, forests and cities to check the environment. For example, they can find out if there is pollution in rivers, or if there are dead trees in forests. This helps people protect the environment more effectively. With the development of technology, drones will be used in more fields. They will bring more convenience to our life and help low-altitude economy develop better. 1. What is the main tool of low-altitude economy according to the passage? A. Cars B. Drones C. Planes D. Ships 2. Why is drone food delivery faster than traditional delivery ways? A. Drones are bigger than delivery cars. B. Drones can fly directly without waiting for traffic. C. Drones have more delivery workers. D. Drones can carry more food at a time. 3. What does the underlined word “they” in Paragraph 3 refer to? A. Farmers B. Drones C. Crops D. Pesticide 4. Which field is NOT mentioned in the passage? A. Food delivery B. Agriculture C. Environmental protection D. Education 5. What’s the main idea of the passage? A. Drones are toys for fun. B. Low-altitude economy is developing slowly. C. Drones are widely used in daily life and help low-altitude economy. D. Farmers use drones to spray pesticide. 答案：1.B 2.B 3.B 4.D 5.C 解析： 1. 细节理解题。题干意为“根据文章，低空经济的主要工具是什么？”。根据第一段第二句“Drones, as the main tool of low-altitude economy, are widely used in people’s daily life.”(无人机作为低空经济的主要工具，被广泛应用于人们的日常生活中)，可知答案选B。 2. 细节理解题。题干意为“为什么无人机送餐比传统配送方式更快？”。根据第二段第二句“Unlike delivery cars, drones don’t need to wait for traffic lights or avoid crowded roads.

In 2026, drones are becoming more and more common in our life. They can do many things that we can’t do easily, and they bring a lot of convenience to us. One of the most popular uses of drones is taking photos and videos. Many people use drones to take beautiful photos of scenery (风景). For example, when you travel to a mountain, a drone can fly high and take a bird’s-eye view (鸟瞰图) of the mountain. It can also take videos of weddings, parties and other important events. These photos and videos are more wonderful than those taken by mobile phones or cameras. Drones are also used in emergency (紧急情况) rescue. When there is a flood or an earthquake, roads may be blocked (堵塞). Firefighters and rescuers can use drones to look for people who are trapped (被困). Drones can fly over the disaster area (灾区) quickly and send real-time (实时的) photos and videos to rescuers. This helps rescuers find trapped people faster and save more lives. In addition, drones are used in logistics (物流). Some companies use drones to send small packages, such as books, clothes and small electronic products. Drones can deliver packages to remote areas (偏远地区) that are hard to reach by cars. This solves the problem of “last mile” delivery (最后一公里配送) in remote areas. However, there are some rules for flying drones. We can’t fly drones in restricted areas (禁区), such as airports, military bases (军事基地) and government buildings. We also need to register (登记) our drones before flying them. These rules are important to keep our sky safe. 1. What is one of the most popular uses of drones? A. Sending food B. Taking photos and videos C. Spraying pesticide D. Delivering packages 2. Why are drone photos and videos more wonderful? A. They are taken by professional photographers. B. Drones can fly high and take bird’s-eye views. C. Drones are more expensive than mobile phones. D. They are edited by professional software. 3.

What does the underlined phrase “last mile” delivery mean? A. Delivering packages to the first stop. B. Delivering packages to the final destination, especially in remote areas. C. Delivering packages by car. D. Delivering packages in one hour. 5. Which of the following is TRUE according to the passage? A. Drones can be flown anywhere. B. We don’t need to register drones before flying. C. Drones can help in emergency rescue. D. Drones can’t deliver packages to remote areas. 答案：1.B 2.B 3.C 4.B 5.C 解析： 1. 细节理解题。题干意为“无人机最受欢迎的用途之一是什么？”。根据第二段第一句“One of the most popular uses of drones is taking photos and videos.”(无人机最受欢迎的用途之一是拍照和录像)，可知答案选B。 2. 细节理解题。题干意为“为什么无人机拍摄的照片和视频更精彩？”。根据第二段第二、三句“Many people use drones to take beautiful photos of scenery. For example, when you travel to a mountain, a drone can fly high and take a bird’s-eye view of the mountain.”(很多人用无人机拍摄美丽的风景照片。例如，当你去山上旅行时，无人机可以飞得很高，拍摄山的鸟瞰图)，可知无人机拍摄更精彩的原因是可以飞得高，拍摄鸟瞰图，故选B。 3. 细节理解题。题干意为“当灾难中道路被堵塞时，无人机可以帮助救援人员做什么？”。根据第三段第三句“Firefighters and rescuers can use drones to look for people who are trapped.”(消防员和救援人员可以用无人机寻找被困的人)，可知答案选C。 4. 词义猜测题。题干意为“划线短语‘last mile’ delivery是什么意思？”。根据第四段第二、三句“Some companies use drones to send small packages... Drones can deliver packages to remote areas that are hard to reach by cars. This solves the problem of ‘last mile’ delivery in remote areas.”(一些公司用无人机发送小包裹……无人机可以将包裹送到汽车难以到达的偏远地区。这解决了偏远地区“最后一公里”配送的问题)，结合上下文，“last mile” delivery指的是“将包裹送到最终目的地，尤其是偏远地区”，故选B。 5. 细节判断题。题干意为“根据文章，下列哪一项是正确的？”。A选项“无人机可以在任何地方飞行”，根据最后一段第二句“We can’t fly drones in restricted areas”(我们不能在禁区飞行无人机)，可知A错误；B选项“我们飞行无人机前不需要登记”，根据最后一段第三句“We also need to register our drones before flying them”(我们飞行无人机前还需要登记)，可知B错误；C选项“无人机可以帮助紧急救援”，根据第三段内容，无人机可以在灾难中帮助寻找被困人员，可知C正确；D选项“无人机不能将包裹送到偏远地区”，根据第四段第三句“Drones can deliver packages to remote areas”(无人机可以将包裹送到偏远地区)，可知D错误。故选C。 C篇 In 2026, low-altitude economy is becoming a new growth engine (增长引擎) of China’s economy. Drones, as an important part of low-altitude economy, are changing the way we live and work. Let’s learn about some new uses of drones in daily life. First, drones are used in medical care (医疗保健). Some hospitals use drones to send emergency medicine and test samples between different hospitals. For example, if a small hospital doesn’t have a certain kind of medicine, a drone can send it from a big hospital quickly. This saves a lot of time and helps patients get treatment (治疗) faster. In some remote areas, drones also deliver medicine to people who live far away from hospitals. Second, drones are used in city management (城市管理). Many cities use drones to check roads, buildings and public facilities (公共设施). For example, drones can check if there are potholes (坑洼) on the roads, or if the buildings are damaged. They can also check the environment of parks and streets. This helps city workers manage the city more efficiently. Third, drones are used in education. Some schools use drones to teach students about science and technology. For example, students can learn how drones fly, how to control drones and how drones work. This not only makes learning more interesting, but also helps students develop an interest in science and technology. With the development of low-altitude economy, more and more new uses of drones will appear. Drones will become an important part of our life, and they will make our life better and more convenient. 1. What is the new growth engine of China’s economy in 2026? A. Low-altitude economy B. Drones C. Medical care D. City management 2. How do drones help in medical care? A. They help doctors do operations. B. They send emergency medicine and test samples. C. They take care of patients. D. They build new hospitals. 3. What does the underlined word “efficiently” in Paragraph 3 mean? A. 缓慢地 B. 高效地 C. 困难地 D. 随意地 4. Which of the following is a new use of drones mentioned in the passage? A. Taking photos B. Sending food C. Teaching students D. Spraying pesticide 5. What can we infer (推断) from the passage? A. Drones will not be used in more fields. B.
