同学们在使用方位介词in、on、to时,最容易混淆。为了牢记它们的区别,我自编了一首歌诀,帮助同学们记忆: in表方位范围里; on表两地相独立, 且有部分边同一; to也表示相独立; 但是界间有距离。 When students use the bearing prepositions in, on, and to, they are most likely to be confused. In order to keep in mind their differences, I wrote a song to help my classmates remember: In the table orientation range; On the table is independent of the two places, and some of the same side; To also said that independent; But there is a distance between the boundaries.
