1.highway指城市街道的还有highway，不过这个指的是市区外的可以通行各种机动车辆的交通干线，也可以指我们常说的高速公路。例如：The small village hugs the highway.It would be connected by highway and rail to the capital and by rail only to Russia.2.motorway这个也是指高速公路，会更正式，特指的是为车辆快速通行而修建的专线，美语的话为freeway或者expressway。例如：Several cars piled up after ignoring the fog warning on the motorway.What if he got out on the gridlocked freeway and went down the emergency exit; would the course of his life change?I drove down another back road which will run next to the expressway and saw a frontloader knocking down a house.
