cross, across与through的区别
cross 作动词用，“穿过，越过”的意思。主要表示在物体表面上横穿。如横过马路、过桥、过河等，与go across同义。

Cross (Go across )the bridge, and you will e a big buiding.

cross除了作动词外，还可作名词，是“十字架，十字形饰物”的意思。作名词时，它有较强的构词能力，它所构成的词的某些词义和用法是值得注意的。
比如crossroads是“十字路”或“十字路口”的意思，它的前面可以用a我爱我的中国，但-s是不能丢掉的。
The accident took place at a crossroads.
车祸发生在十字路口。
因为crossroad是基督教的用语，指“十字架的道路”，不是十字路口。《十字架的道路》表示基督徒在信奉基督时要愿意为宗教牺牲，对信徒而言，这是一条很难走的道路。
另外，crossing是工作汇总“渡口”、“横道线”或“（铁路与公路的）交叉点”。
