--- Is your father in?--- No, he ______ for three hours. A．was out B．has been out C．went out D．has gone out

Answer 1

B

试题分析：句意：你的父亲在家吗？不，他已经出去三个小时了。for three hours表示一段时间的时间状语，句子用现在完成时，be out 表示状态，动作可以延续，故选B 点评：非延续性动词向延续性动词的转变熟记一下几个： leave --- be away,  borrow --- keep,   buy --- have,  begin/start --- be on,      die --- be dead, leave --- be away from, fall asleep --- be asleep
