So far in 2020, COVID-19 might be one of the best-known terms. Many people are asked to stay at home because of it. Then how can people date with their friends, have a meal with their relatives, or even walk their dogs in quarantine? Drones may be the answers to the questions.         Today, drones are created and used in many different ways, which is especially good news for some lazy people. For example, drones can help people deliver packages or food, check the health of plants, save lives, and even walk the dog. Using a drone to walk dogs may be a crazy idea, but a man really did that. In California, a man, Vakis, keeps a dog whose name is Oliver. While Vakis was lying comfortably on his couch on the balcony, he was also controlling a drone, which was walking Oliver for him. Oliver was kept on a leash which was tied to the drone. And it was taught to follow the drone.         Another man also used a drone to walk his dog even more smartly. He set up a route in his drone, and the drone itself led his dog out and home. He didn’t even have to control the drone! Through the camera on the drone, he could make sure if both are safe by just watching the video the drone sent back. Drones may change our life more in the coming years. Hundreds of drones might fly high above, and drop or send people food, presents, medicine or anything needed.  * term 詞 leash 牽繩 route 路線 control 控制
