the ‘smart city’ project, launched by the University of Cantabria seven years ago.” 和文章最后一段 “The Santander smart project is attracting the attention of larger cities in Europe and elsewhere that are looking for smart solutions to urban problems.”可知，文章旨在介绍智能城市项目。故B项正确。
二、七选五（每小题2分，共10分）
There have been a lot of comments recently surrounding 5G, the next generation of wireless technology. 9. ? How might it change our lives?
5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. Earlier “G” systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity (容量). 10. . It is expected to permit more users to do more things at a faster rate.
However, technology experts say there is a major way that 5G is different from the earlier systems. 11. . It will affect many more devices and industries than other “G” versions.
5G will help fuel future “smart cities” by connecting sensor networks. 5G is also expected to connect self-driving cars and support new technologies involving virtual reality(虚拟现实). Higher 5G speeds could also permit doctors to commonly perform remote medical operations. Factories and businesses could use 5G technology to increase automation and improve the collection of information.
12. . The increased data flow across 5G networks would give Internet attackers a lot more possibilities to steal and misuse data. In addition, the wider use of a 5G wireless network
means any breakdown of the system would have more widespread and severe results. Such difficulties could affect public safety. 13. , or a network breakdown could cause self-driving vehicles to crash.
A. Why is 5G so popular B. What is this technology C. Every coin has two sides
D. The new 5G system promises more of the same E. It will move beyond mobile network technology
F. A breakdown of 5G networks may cause economic losses G. A failure during a doctor’s remote operation could lead to death 【答案】9. B
10. D
11. E
12. C
13. G
【解析】本文属于说明文，介绍5G技术以及其优点，同时也存在的安全风险。
9. 分析文章结构可知，本文属于总分结构，文章主要就第一段的两个问题展开来写，根据第二段“5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system.”可知，第一个问题是关于5G概念，故选B。
10. 根据前一句“Each new technology brought major improvements in speed and greatly increased network capacity (容量).可知，每一项新的通信技术都会带来速度提升，容量扩大。D选项，而5G在此基础上会带来更多的东西，本句中的“of the same”与前一句呼应，切题，故选D。
11. 根据后一句“It will affect many more devices and industries than other “G” versions.”可知，与其他的四代通信产业相比，5G会影响更多的设备和产业。E选项，它的影响超过移动网络技术切题，在句中起递进说明作用，故选E。
12. 根据后文“The increased data flow across 5G networks would give Internet attackers a
lot more possibilities to steal and misuse data.”可知，本段主要讲述5G技术可能存在的风险，故选C。
13 根据后一句“or a network breakdown could cause self-driving vehicles to crash.”可知，网络故障可能会导致自动驾驶汽车出车祸，讲述5G技术对公共安全可能造成的不利作用。G选项，远程手术的失败可能造成病人死亡。本句是对前一句的具体阐述，切题，故选G。
