地点介词: in/on/at

定义 / 说明

地点介词帮助我们表达人或物在哪里。最常见的基础介词是 inonat。通常 in 表示在空间内部,on 表示在表面上,at 表示一个点位或整体地点。这些词虽然小,却很重要,也常常较难,因为选择取决于意义而不只是直译。

关键规则

  • in 用于在某空间内:in the room, in the bag
  • on 用于在表面上:on the table, on the wall
  • at 用于点位或作为一个地点看待的位置:at home, at school, at the station
  • 有些表达必须整体记忆:at home,不是 in home
  • 根据概念选择介词:内部、表面、点位/地点。
