"Be located in" 和 "be located on" 都是用来描述位置的短语。
"Be located in" 通常用于描述建筑、房屋、城市或区域等相对更大的范围内的位置,表示某物体位于某个区域内部。例如:
Beijing is located in northern China. (北京位于中国北部。)
The hotel is located in the city center. (这家酒店位于市中心。)
"Be located on" 则通常用于描述物体、建筑等占据的空间范围的表面位置,一般是指在某个较小的区域、物体表面等。例如:
The painting is located on the wall. (这幅画挂在墙壁上。)
The airport is located on the outskirts of the city. (机场位于市郊。)
总之,"be located in" 表示具体位置的区域内,而"be located on" 表示所在位置在某个更大的物体表面上。
