题目内容：

across the world ,all over the world ,around the world都有全世界的意思,做句子时可以替换吗?
它们之间有什么区别吗?

优质解答

all around the world
= all over the world
= throughout the world
= everywhere in the world
复数名词 + across the world 与上述同义.
而单数名词 + across the world 则有"穿越"之意,
around the world 或 all over the world , 会比across the world 更为普遍~
