以前看见了关于among 和between用法的文章都是直接跳过，以为是个小儿科的知识点，直到有一次遇见了between描述三者以上之间的关系时才引起重视，仔细研究后将心得分享给广大读者：
1. between 介词和副词，prep.之间;(空间上或时间上)在…中间;(数量、重量、距离等)介于…之间;分隔着;从（一地）到（另一地）;合用
adv.(空间或时间上)介于…之间
一般情况下用于两者之间；但是，也可以用于表示三者或三者以上的（时间、空间、数量、重量、距离、年龄等）之间，此时表示被修饰的人或物的左右边各一个某物或人：或表示多者的两两之间，在（两个人、群体或事物）之间；between后接的对象一般都是具体的、整齐的、并具有个体分离性。
常用句型是between……(A,B,或C,D)and+最后一个：
