Across和OVER
这两个介词,意思往往相近,但仍有一些区别。
1. 二者都可用来表示”处于或达到一条线、一条河或一条路的另一侧”(与细而长的物体相对而言的位置或动作)
例如:
We walked over/across the road.
See if you can jump over/across the stream.
His room’s just over/across the corridor.
We’ll be over/ across the frontier by midnight.
表示发生在水面或者水的上方的动作，可以用OVER, 但在水中发生的动作不能用OVER.]
如:
How long would it take to swim across the river?
在这里就不能用OVER.
2. 两者都可表示”处于……的另一侧”, 但为表示到达另一侧的动作,则只能用OVER.
If we can be over/across the fence before sunrise we’ve got a chance.
When I last saw him he was climbing very slowly over the fence.
3. 两者都可以表示某一范围内的动作。

但是， 表示从一定范围的一边到另一边,则只能用ACROSS.
