阅读理解。 There are many different kinds of communities around the world. Communities can be urban (in a city), suburban (near a city), or rural (in the countryside, far from a city). Urban communities usually have many neighborhoods, where people often live close together in apartment buildings or small houses. Streets in these neighborhoods often have lots of people and many stores and businesses. People in urban neighborhoods often walk or take public transportation to get to places. In suburban communities, people live in separate houses. Stores and businesses are not usually nearby, and people often have to drive to get there. Some suburban communities have public transportation, and others don't. In rural communities, people often live far from each other, not in neighborhoods. There isn't usually any public transportation, and people have to drive everywhere. Whether in urban, suburban, or rural areas, some communities are friendly, and others aren't. For example, in some communities, people know their neighbors, they help each other, and their children play together all the time. In other communities, people sometimes don't even know their neighbors' names. In the old days, most people around the world lived in small towns and villages, where they knew their neighbors. These days, more people live in large urban communities. Experts think that in the future most people will live in 'megacities' of more than ten million people. Will there be friendly neighborhoods in these communities in the future? Time will tell. 注：(1) community 社区 (2) whether 不管…(还是…) (3) expert 专家 (4) neighborhood 四邻, 街坊；住宅区 (5) separate 各自的, 分开的 1.
