etween 是可以用于两者以上的,但原则是比较对象必须是独立的,能够区分的,不是一组的.
比如,Can you tell the differences between English,Chinese,and Arabic?
而如果比较对象被划分为一组,则需要用among,
比如,a discussion among the members
choosing among many cheeses
另一种情况,如果主句或上下文表明between比较的对象必须是1对1进行的,
那即使比较对象是一组也必须用between.
比如,agreement合约条款签署对象必须是一对一的,
An agreement was signed between the five countries.
所以原句应为the connection among girls.
如果用between,则需改成the connection between Sally,Jane,Ann and Tina.
除非上下文有显示girls之间的比较是一对一的.
