18. For more than 300, 000 years, human beings have paid much attention to developing technology to make our life easier, faster and more comfortable with the help of machines and tools.
Thanks to the modern technology, humans live longer and more healthily, and are able to get better food, medicine and shelter. We can be proud of this progress. In the past, many poor people died from hunger and diseases. But now many diseases can be cured successfully.
We need "more", more food, more shelters, more medicines, etc.. And up to now, technology has been used in various fields in the city, including intelligent (智能的) education, intelligent medical treatment, intelligent tourism, smart transportation and especially the field of 5G. Recently, Central China's Hubei province has built more than 300 5G base stations (基站) and achieved full 5G signal coverage (信号覆盖) in some of its cities. A dozen 5G experience centers have been completed in cities including Xiaogan, Yichang and Jingmen.
With the development of the high technology, our living conditions have already been improved a lot. But we still have a long way to go. So, we ought to face all the challenges positively to make it serve us better.
