in vs on 在 by means of上的区别:
in - 就是by means of, 用什么方法。这个比较泛泛和笼统,外延广。
on - 这里的by means of,有前提或限制。因为on本身常常表using as a means of conveyance or of supporting or supplying movement,是通过运载模式的方式,因此Used to indicate a means of conveyance,进而演变成Used to indicate availability by means of,最后成为:by means of (something considered as a mode of transport)。 因此:on的by means of强调的是一种转变的模式。 buy house on mortgage,就是用贷款的方式,最终把房子转变成自己的财产。这是一种置产的模式,隐含着所有权的转换。因此on的by means of强调一定的内涵限制。
