题目内容
18．Look，Peter is still reading in the library，He _____ here for two hours．（ ）| A． | has come | B． | has been | C． | was | D． | came |
分析 看，Peter仍然在图书馆里看书，他在这里已经呆了两个小时了．
解答 答案：B． 根据for two hours可知这里是for引导的时间状语，"两个小时"表示一段时间，表示过去的动作一直持续到现在，应该用现在完成时态；现在完成时态的结构为have/has+动词的过去分词，排除CD；故又因为come是瞬间性动词，不能持续一段时间，后面跟延续性动词，所以要用have been，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．本题注意短暂性动词和延续性动词的区别．
