How to distinguish "over" and "across"?
When referring to the sixth edition of the Oxford Advanced Dictionary,we can discover that the first defination of "across"(used as adv.) and the seventh(maybe) defination is exceedingly similar,and yet they are not exactly the same,for we can only use "echoing across the field" rather than over.
I would be grateful if somebody could help.
ATTENTION!this is not merely a translation

通常会把across和over搞错的时候,它们所表达的意思是"穿过",across就是指从东西的内部穿过,比如"穿纸",用across就表示把纸弄破,从纸中间穿过.
over是指从竖直上方穿过,再以"穿纸"为例,就是把纸放在水平面上,然后从上方有一定距离出通过.
lz是想问这个么?

在谈到先进的第六版牛津字典,我们可以发现,第一defination"跨越"(用作ADV). 七、(可能)defination极其相似,但不完全相同,因为我们只能用"反映整个领域",而不是结束. 我希望能有人可以.

怎样区别"over"和"across"
当我们查阅牛津高级词典第六版时就能发现"across"(副词)的第一个定义和第七个定义非常相似,但并不是完全相同,因为我们只可以用"echoing across the field"而不能用"over"
