Sally has become a computer programmer since one year ago.错在哪 为什么`

has become中become是个短暂动词
since one year ago用现在完成时是对的
但要用状态的has been来表达
Sally has been a computer programmer since one year ago.

其实还可以说
Sally became a computer promgrammer one year ago.

Sally has been a computer programmer since one year ago

or

Sally became a computer programmer one year ago

为什么?时态,只有中国教育才注重的东西
