高中英语完成时

为什么选A不选B?

A.studies B.studied? C.is studying D.has been studying
为什么这个选D 如果把Cathy is换成 Cathy was 是不是选B呢?为什么?
谢谢了!

1.一丝不是说在农场已经工作五年,他意思是毕业后没有教学,而过去五年在农场工作,强调过去式.现在完成时的话,说明现在还在农场工作,但事实是他在教学.明白了吗?这道题很值的琢磨.出的有水平.
2.说明事情正在进行,is taking,如果改成 took,后边就是studied,此句用的是现在完成进行时,她一直在学英语.换成was,就是had been studying,是过去完成进行时.

高中英语完成时---Have you been teaching here since graduation? ---N 这个英语错在哪儿i have been teaching here for 30 years when you grad I have been teaching English since 1986.改为同义句 have been here 后面可不可以用since I HAVE BEEN HERE SINCE TIME they have been here since 2000 why have you been here? I have lived here since then还是I have been here since then对啊? I have been teaching in this school since three years ago.变同 i have been teaching since 2006中的teach为什么要加ing? 1.They have been here since 2000.___ ___ We have been studying english since we move here
