给你简单分析一下:

"have"和"own"都可表示"拥有"的意思,但用法意义上有一些区别(别的词义我们这里不讨论):

*have的"拥有",多指"持有,存在".
如
the table has four leg.桌子有四条腿.
they have five cars.

*own的"拥有",多指"所有,具有所有权",其主语多指人(也可以是拟人化的动物/物品).
Who owns this house?
谁拥有这幢房子？

所以说,我们一般不会说:the table owns four leg.
一定要这样说,也可以,但象是给桌子赋予了人的意识,它"拥有"4条腿.

这样说,楼主能理解么.(这两个词其他的意思,我就不说了,也没什么可比性,且楼上将词典COPY的很全,你也可以看看,呵呵)
