1. (2023高一下·青阳期中) 阅读理解

We are in the middle of another technology revolution. The digital economy will contribute 48% of GDP in China in 2035, up from 23% in 2020.

With the implementation（实施）of 5 G and consumer AI, smart cities are no longer just a concept. Indeed, in a surprising silver lining to the Covid-19 pandemic, smart city apps have shown they can help China contain the spread of the virus, helping to recover the economy. Other successful examples include applications for better traffic management, flood control and crime reduction.

The number of smart street lights required in China is estimated at 13 million assuming a 30% penetration rate（安装率）of all street lights in 2025. When the network of smart street lights increases further, it will also likely expand to cover more functions. In addition to basic lighting, it could include monitoring cameras, auto-police calling when the data shows abnormalities, weather information collection, WI-Fi hotspots converting telecommunication signals, e-vehicle chargers, and so on.

In order to deal with the difficulty of parking, Shenzhen has combined 5 G and AI to enhance the efficiency of car park usage. For example, drivers can seamlessly book a parking space at a hospital at the same time as scheduling a doctor's appointment. Drivers also know whether all of the parking spaces are occupied at the time of the doctor's appointment and can choose other transportation. Besides, Robots and sensors installed in the auto-valet parking lots work together to find a space and park the car for drivers, which provide much convenience for drivers.

With more technology applications, there is bound to be disruption（扰乱）to existing activities and the labour they require. If smart cities help driverless cars to take off, the thousands of drivers of taxis or delivery drivers that find low skilled employment in China's cities could be displaced and struggle to find alternative employment. New jobs will certainly arise from the implementation of smart city technology, but will likely require different skills and knowledge to those being displaced. The government will need to assist those whose employment is disrupted to find alternatives.
