Question

【题目】阅读短文，按要求完成各题。

How has technology made your life easier? When you go to a shopping mall, you can enjoy free Wi-Fi there. 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 (电子的) 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 how full they are and tell workers when 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.

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.

【1】It is a city that uses digital technology.

【2】The USA./America.

【3】By using sensors and 5G networks.

【4】No, it won't.

【5】About 60 percent of people worldwide will live in smart cities.

【解析】

这是一篇说明文。文章主要介绍智能城市。智能城市指的是使用电子科技的城市；同时介绍了智能科技在世界一些城市的使用情况及优势；并提到了智能城市的发展前景。

【1】根据第二段“a smart city is a city that uses digital (电子的) technology”可知智能城市指的是使用电子科技的城市。故答案为It is a city that uses digital technology.

【2】根据第三段“In the US cities of Boston”可知城市波斯顿属于美国。故答案为The USA./America.

【3】根据倒数第二段“Smart cities will allow us to save resources. By using sensors and 5G networks”可知通过使用探测设备和5G网络，智能城市帮助我们节约能源。故答案为By using sensors and 5G networks.

【4】根据最后一段“it won’t be long until more cities join in”可知有更多的城市加入，未来不会花很长时间建立智能城市。此处是否定的回答。故答案为No, it won’t.

【5】根据最后一段最后一句“Tech Republic estimates (估计) that by 2050, about 60 percent of people worldwide will live in smart cities”可知到2050年全世界大约有60%的人住在智能城市里。故答案为About 60 percent of people worldwide will live in smart cities.
