across是横穿，through是有包围性的穿过，那么如果是表面上的纵穿用英文怎么表达

想辨析最好还是看英文例句~
across/cross:
go across the street
cross the street

through:
go through the forest
through the roof

span:
a history spanning more than 5000 years

cover through / across

go through

go across

across,through都有穿过的意思，across偏向于平面的穿过，如across the road;而through偏向于空间上的穿过，如through the forest

如果是具体的事物，用across就可以了，如果是抽象的事物，像历史啊什么的用span
