题目内容
How has technology made your life easier? When you go to a shopping mall, you can enjoy free Wi-Fi there. (A)When you want to take a taxi, you can book one with your phone. In fact, all of these things can be seen as the first building blocks of a smart city.
The idea of a smart city was first suggested by tech company IBM in 2010. Generally, a smart city is a city that uses digital technology, such as 5G networks and the "internet of things", to improve urban planning, save money and resources (资源), and make our lives more convenient.
Cities like Boston, Amsterdam and Copenhagen are already using smart technology to improve public services. In the US cities of Boston and Baltimore, smart trash bins can sense (感知) how full they are and tell workers when (B)they need to be cleaned. In Amsterdam, traffic is monitored (监测) and adjusted according to real-time data gathered from sensors around the city. There are fewer traffic jams.
Smart cities will allow us to save resources. By using sensors and 5G networks to check the usage of water, gas and electricity, city managers can figure out how to use these resources more efficiently. For example, water and gas pipes (管道) could remind repair workers when there is a leak (泄漏). Air pollution could be more closely monitored, too.
(C)Of course, it will take time to build the smart cities of the future. But since we've already seen successful examples, it won't be long until more cities join in. Tech Republic estimates (估计) that by 2050, about 60 percent of people worldwide will live in smart cities.
