问：

在人生地不熟的环境迷路了。我想说：请问警察局怎么走？我这样说：Could you show me where is the police station?正确吗？

答：

一般人迷路，会直接找人问路，像你这么谨慎，要先找警察局才肯问路的，还真不多见。在此先解决你的问题：
Could you please show me where the police station is?
请问警察局怎么走？

若是下次迷路，正巧面前有位本地人看起来很安全，你可以试着问：
Could you show me where we are on this map?
请问这里是这份地图上的哪里？

I'd like to go here. [showing that person where on the map] Could you tell me how to get there?

我想去这个地方。（拿地图给对方看）请告诉我要怎么走？

Could you tell me how to get to the Orlando West Holiday Inn?
