I don’t smoke now, but I ____for almost ten years.

I don’t smoke now, but I ____for almost ten years.
A. ever smoked B. have ever smoked
C. had ever smoked D. was ever smoking
为什么选A。这句话是什么意思？考点是一板过去时及其被动式，怎么讲？

Answer 1

选择A，for+一段时间通常用于完成时，但是上下文明确说明，这件事已经结束了，就只能用一般过去式。
如：The couple have lived here for 3 years.
He smoked for 20 years, but he gave it up.
