--You speak very good English!--Thanks a lot.I ____ in America for five years
--You speak very good English!
--Thanks a lot.I ____ in America for five years
A worked B work C was working Dhad worked
为什么?求详解

Answer 1

答案是A.
此人正在和“我”对话,显然他此时不在美国.不可能选B,因为一般现在时表示经常或习惯性的动作.不可能选was workign ,因为和for five years 对不上.不可能选过去完成时,因为文中没有过去时的提示.只剩下A了,表示我曾经在美国工作过.
这种选项还算简单的.高考题是在worked 和have worked 之间选,错误率此时急剧上升.
