我和爷爷出去，今天我们不做公交车，要坐地铁了。早听说郑州有地铁，今天我就来坐一坐吧。
Grandpa and I are going out. Today we are not going to take the bus. We are going to take the subway. I heard that there is a subway in Zhengzhou. I'll take a seat today.
我们一进地铁站，就看见一列地铁缓慢的驶过来，跟坐火车时一样的感觉呀，平稳而舒服，环境也干净，车票还是跟公交车一样便宜，车上人不多，有的是静坐聊天，有的在玩手机，到站了就 自觉有序的下车。
As soon as we got into the subway station, we saw a train coming slowly. It was the same as when we took the train. It was smooth and comfortable, and the environment was clean. The ticket was still as cheap as the bus. There were not many people on the bus, some were sitting quietly and chatting, some were playing with mobile phones, and when we got to the station, we got off in order.
怎么样，大家有时间也来享受一下吧。
Well, let's enjoy it when you have time.
