My father isn’t at home. He home for a week.A. has left B. has been away from C. left

问题补充：

My father isn’t at home. He home for a week.

A. has left B. has been away from C. left

答案：

解析：句意：我父亲不在家。他离开家一周了。leave离开，是非延续性动词，不与for短语等表示成段的时间状语连用；be away from远离，是延续性动词，可与成段的时间状语连用。left是leave的过去时，此处说已经离开家一个月，应用现在完成时。故选B。
