after，at the back of的词汇辨析
这些词均有“在……后面”之意。
after 和behind用来表地点时，前者强调的是顺序的先后，而后者侧重方向和位置的前后关系。请比较：The student sat after me.那个学生坐在我后面。(我坐在他前面)。The student sat behind me.那学生坐在我背后。after与behind用于指时间时，前者强调时间的先后顺序，而后者则着重于表示“落后……”或“迟于……”的概念。试比较：Who ruled after James I?詹姆斯一世之后是谁统治的?You are forty minutes behind sch
at the back of 这个前置词短语既可指具体的位置的先后，又可用于指抽象的概念。
