题目内容
14.The telephone _______ four times in the last hour,and each _________ for my roommate.( )| A. | has rung; was | B. | was ringing; is | C. | had rung; was | D. | rang; has been |
分析 在过去的1小时里电话已经响过4次了,每次都是找室友的.
解答 答案:A.
根据 in the last hour可知,"在过去的1小时里"表示一段时间,此句表示表示过去发生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;主语是The telephone,是名词单数形式,应该用助动词has,再根据and each _________ for my roommate,这里描述的是过去所发生的事情,故使用一般过去时,each每个,各个,做主语时谓语动词用单数,故选A.
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.注意各种时态的结构及其用法.
