题目内容

13．Mr．Brown his hometown since he the army．（　　）

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

分析 Brown先生自从他参军以来就离开了家乡．

解答答案：B．
根据关键词 since he ____the army可知，这里强调一种持续的状态；所以本句使用现在完成时态，其构成为：have/has+过去分词，主语Mr．Brown是第三人称单数形式，所以助动词用has；其动词要用延续性动词be away，其过去分词为been away，since在这里是自从…以来，它引导的从句应该用一般过去时形式，join的过去式形式是joined，故选B．

点评判断动词的时态，要通过所给的时间状语、提示词或语境去判断动词存在的状态．注意容易混的动词的用法．
