英语:on the top of和at the top 什么时候可以交换of的所有具体区别？

"Of"一般用于在名词或动词之后，表示对象、方式、原因等。，The book is on the table at the top.，Of my family, we all speak English.，，"On"则常用来表示地点、时间或程度等。，We will arrive at the airport on time.，On Sunday, I usually watch TV in the living room.，，而"at"除了表示地点外，还可以表示相对位置或时间点。，She sits at the edge of the pool.，At this moment, the sun is shining brightly on the beach.

In fact, it is not necessary to expound on the difference between "on" and "at" in detail. On emphasizes that the "surface" while at emphasizes that the "point". Therefore, on the top of ... refers to the surface of... placed at the top position. At the top of ... refers to the position of... at the top.

主要的区别在于 "表面" 和 "点" 的使用。"on" 表示在 ... 上方，强调的是 "面"；而 "at" 表示在 ... 在位置上，强调的是 "点"。"on the top of..." 指在 ... 在表面上，"at the top of..." 指在 ... 在顶部的位置。
