题目内容
6．He the city since he graduated from college．（ ）| A． | has left | B． | left | ||
| C． | has been away from |
分析 自从他大学毕业后，他就离开了这个城市．
解答 答案：C．根据语境since he graduated from college（ 自从他大学毕业后），可知主句的动作应是过去开始并延续到现在的动作，故主句应为由延续性动词构成的现在完成时态（基本结构：主语+have/has+动词的过去分词），left为终止性动词故不能用，故应用短语be away from表达状态．故答案为C．
点评 本题考查现在完成时态的用法，现在完成时态是指已经完成的动作对现在造成影响或后果，或者过去某一时间开始并一直持续到现在的动作或状态．
基本结构：主语+have/has+动词的过去分词．考生在此基础上结合语境可正确作答．
