Question

【题目】 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. 【1】 The idea of a smart city was first suggested by tech company IBM in 2010.【2】There are many examples in our lives, such as 5G networks and the “internet of things”, they are used 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 【3】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).【4】

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. 【5】

A.In the US cities of Boston, smart trash bins can sense how full they are and tell workers when they need to be cleaned.

B.In fact, all of these things can be seen as the first building blocks of a smart city.

C.Tech Republic estimates(估计)that by 2050, about 60 percent of people worldwide will live in smart cities.

D.Air pollution could be more closely monitored, too.

E.A smart city is a city that uses digital (电子的) technology.

【解析】

本文作者向大家介绍了智慧城市。主要介绍它的优点，事例以及未来的前景。

【1】句意：事实上，所有这些都可以看作是智慧城市的第一个组成部分。

根据上文“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.（当你去购物中心时，你可以在那里享受免费Wi-Fi。当你想乘出租车时，你可以用手机预订。）”可知此句是“事实上，所有这些都可以看作是智慧城市的第一个组成部分。”故选B。

【2】句意：智能城市是一个使用数字技术的城市。

根据上文“The idea of a smart city was first suggested by tech company IBM in 2010.（智能城市的概念最早是由IBM科技公司在2010年提出的。）”和下文“There are many examples in our lives, such as 5G networks and the “internet of things”, …(在我们的生活中有很多例子，例如5G网络和“物联网”，……)”可知“智能城市是一个使用数字技术的城市。”故选E。

【3】句意：在美国的波士顿，智能垃圾箱可以感知垃圾的装满程度，并告诉工人何时需要清洗。

根据上文“Cities like Boston, Amsterdam and Copenhagen are already using smart technology to improve public services（波士顿、阿姆斯特丹和哥本哈根等城市已经在使用智能技术改善公共服务）”可知此句是“在美国的波士顿，智能垃圾箱可以感知垃圾的装满程度，并告诉工人何时需要清洗。”故选A。

【4】句意：空气污染也可以得到更密切的监测。

根据上文“For example, water and gas pipes (管道) could remind repair workers when there is a leak (泄漏).（例如，水管和煤气管在发生泄漏时可以提醒修理工人。）”可知此句是“空气污染也可以得到更密切的监测。”都是列举事例说明。故选D。

【5】句意：科技届估计，到2050年，全球约60%的人口将生活在智能城市。

根据上文“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.（当然，建设未来的智慧城市还需要时间。但既然我们已经看到了成功的例子，那么很快就会有更多的城市加入进来。）”可知此句是“科技届估计，到2050年，全球约60%的人口将生活在智能城市。”故选C。
