用英语学英语口语：Bus和Coach的区别口语训练
我们在能用中文表达bus是公交车，coach是长途班车的基础上，用英语表达它们的意思，用英语积累英语，同时训练自己的英语口语能力。
在美国，a bus can be a coach, and a coach can be a bus.
But some difference between them still arises.
我们基本上可以这样用英语描述bus和coach，不一定全面，但其中的重要词汇必须要变成自己的英语使用能力。
Bus：
Well a bus usually runs down streets around a city,or inside a city. A bus stops at every bus stop on its fixed route.So we say Bus Route 1,Route2,etc.A bus route is a bus line(一路车，二路车).
travel around or inside a city, from one bus stop to another stop, bus route是表述bus的必备英语词汇。
route (r-out)
Coach：
Well a coach travels long distances on the highway from one city to another city,or between cities, or even between countries, like the coaches in Europe.
看得出用英语学英语，我们可以“横向”获得哪些有用的英语表达没有？
