高1・高2向け｜英語長文問題96（科学技術）145語＋和訳・解答解説

Drones have changed a lot in the last few years. At first, many people used them only for fun or short videos. Today, drones can fly more smoothly because their sensors and control software are better. Some drones can avoid trees and wires, and they can come back to the starting point when the battery is low. This makes them easier and safer to use. Drones are also useful at work. Farmers use them to check fields and find places that need water. Rescue teams search for lost hikers, and they can send a small light or a radio. Delivery companies test drones to carry small packages to remote areas. In cities, drones help engineers inspect bridges and roofs without climbing high places. As batteries improve, drones may fly longer and do even more jobs. However, pilots must follow local rules and respect people’s privacy.
