have always been (done/doing) 区别?
always加了个频度副词，对语法无影响。have done是现在完成时，have been doing是现在完成进行时，强调这个动作一直在做，可能还要继续做下去；如：I have been working here for 10 years.(以后还要在这里干下去）I have been waiting for you the whole morning!(抱怨等得久了）

一般解释会说“两者之间”用between，三者或以上用among。这个说法有点教条，要看实际情况。比如树间长满了鲜花。(好多树呀）如果是路边的树，考虑用between，因为花在每两棵树之间；若是换个环境到树林里，还是用among合理。还有个更好理解的例子，我国新疆地区的地形是“三山夹两盆”，这里肯定要翻成between啦

should have prefered to 怎么理解？
