"on and in" what different?
on and in的词组和个有什么用!

介词都是有来源的.
on最初是表在什么上.一维或二维的.in表在什么里,二维或三维的
以后一切用法大都从中衍生.
具体讲起来很复杂,我也懂很少.
介词的意义
1．物体在空间的定位
给一个物体在空间定位需要两个或更多实体
Dirven(1993)做了如下分析,他认为at,in,on是最基本的也是最普遍的介词.
At 指在方向上的某个点：meet at the corner
On 指的是一种物理上的接触,必须把接触的地界看成是一维（一条直线）或二维的空间（一个平面）
In 只包含在地界之内,因此需要把地界看成是二维或者三维空间（一个平面或一个立体空间）
Sam is in the room.
空间意义对于介词来说是最典型的.
当介词的空间意义能从物质到精神空间上延伸,这种延伸不是偶然的,而是循序而成抽象概念的.
由空间意义引申的.
如he is in the bed.
he is on the bed.
是不一样的.on可能是躺在床板上,如二维.
in可能是被床单被子等盖着,像三维的.
至于其他的引申,估计得慢慢研究了,但基本上都是从空间概念延伸发展的
比如interested in,count on等.
如At 的延伸
空间意义at the station
时间 at six o’clock
状态 at work
领域范围good at guessing
方式at full speed
环境at these words(he left)
原因laugh at,irritation at
