1.When answering this question, you can compare the types and availability of transportation options in big cities versus small cities. In big cities, there are usually more diverse and comprehensive transportation systems, including subways, buses, trams, taxis, and ride-sharing services. These options provide convenience and efficiency for residents and visitors. 2.In small cities, transportation options might be more limited, often relying on buses, personal vehicles, and sometimes bicycles. Public transportation may not be as frequent or extensive, and the infrastructure might not support as many options. You can also discuss the impact of these differences on daily life, commuting, and accessibility.
