modernization and urbanization bring both benefits and problems. in order to solve the problem of housing, high-rise buildings have been and are being put up in ever greater numbers in more and more big cities.
high-rise buildings have their advantages and disadvantages, of course. in urban areas where land is epensive, they take up less space. some people say that high-rise buildings can give a city striking beauty. some buildings are apartments, which can house hundreds of families under one roof.on the other hand, high-rise buildings may be dangerous.what if there is a fire or an earthquake? what if power and water are in short supply? in addition, high-rise buildings/blocks may not be suitable for children and old people.
