Public transportation is anything that the government runs or operates, such as buses, trains, and subways. 公共交通由政府运营，包括公共汽车、火车和地铁等。

Lucy says that she likes her job but that "it takes over an hour to get there from" her "part of town." 露西说她喜欢她的工作，但“从”她“这边到那里要花一个多小时。”

To get there means to arrive. Her part of town is her area of town. 到那里意思是到达。她那边是指她居住的城区。

"First," she says, she walks "three blocks to the subway station" and swipes her "monthly pass to get through the turnstile." “首先，”她走“三个街区到地铁站”，然后刷“月票通过旋转门”。

A subway, "subway," (one word) is a train, usually that goes underneath the ground. 地铁（subway）是一种火车，通常在地下跑。

In some cities, such as Chicago, they have an elevated train, which they call the El. 在有些城市，比如芝加哥，有高架火车，他们称之为高架线（El）。

Subways are usually, however, below the ground; they're underground. 然而，地铁通常在地下；所以叫地下铁。

In fact, in London, the subway is called the Underground or the Tube. 在伦敦，地铁被称为地下铁或地下线路。
