哪位大哥大姐帮我用英文介绍一下地铁的

Nowadays, Subways have been one of main Trasportation in each city. Subways are special kinds of trains that are usually built underground and are often found in big cities. They are typically made up of multiple train lines that start and end in different places, and sometimes intersect each other in between, allowing passengers to get from one place to another. By operating underground, they help large numbers of people to get around easily, since they still allow space for people to walk, drive, and take busses up on the street. Everyday I go to work by subways.
