TRIP OR JOURNEY? 用 trip 还是 journey？
A trip usually involves you going to a place and back again; a journey is usually one-way. A trip is often shorter than a journey, although it does not have to be. * trip 通常为往返旅行，journey 通常为单程旅行。trip 的行程常较 journey 短，但并非一定如此：
a trip to New York 去纽约的旅行
a round-the-world trip 环球旅行
It is often short in time, even if it is long in distance. Journey is more often used when the travelling takes a long time and is difficult. In North American English journey is not used for short trips. 即使距离远，trip 所花时间常常不长。如果旅程长且艰难较常用 journey。在美式英语中，journey 不用以指短途旅行：
(BrE) What is your journey to work like? 你上班的路程如何？
