1. (2018七上·南沙期末) 阅读下列短文，从每题所给的 A、B、C 和 D 项中，选出最佳选项。

You may know a lot about smartphones. But what about smart cities?

Imagine living your life like this: When you wake up in the morning, you say "Open the window" to the computer and it opens the window. The sunshine is shining and the birds are singing. Then you finish breakfast and sit in front of your desk and begin to have classes through the Internet. With the help of building a smart city, this may become true one day.

A smart city uses digital technologies(数字科技）such as the Internet to improve city planning, save resources(资源) and make our lives easier. For example, people live in smart cities, where there is Internet almost everywhere. They can do many things at home, such as booking train tickets, paying water bills and shopping online. What a convenient life it is!

Now China is making some cities smarter. For example, Guiyang is going to build free Wi-Fi in the whole city. Tianjin plans to start a smart city program to solve traffic problems. Guangzhou is creating a smart city, so everyone in the city should play a role in creating a smart city.
