题目内容
2.Tom,you play the violin so well.But I ______ you can play the violin.( )| A. | didn't know | B. | don't know | C. | hadn't known | D. | haven't known |
分析 汤姆,你的小提琴拉得真好.但是我以前都不知道你会拉小提琴呢!
解答 答案A根据句意作者表达的意思是"以前不知道你会拉小提琴",但是现在说话时知道了,所以"不知道"对方会拉小提琴是过去的事情,所以应用一般过去时态,故选A.选项B是一般现在时,表示经常性、习惯性的动作;选项C为过去完成时,表示过去的过去;选项D是现在完成时,表示过去发生的动作对现在造成的结果或影响.故排除选项B、C、D,答案为A.
点评 本题考查一般过去时,表示过去发生的一个动作.做题时,要注意分析动词形式及具体语境,想象在那个特定的时间动作所发生的背景,这个动作是经常性动作、一般性动作、进行性动作、完成性动作还是将要发生的动作.要根据四个选项时态的特点,结合句子动作发生的时间,选择正确的时态.
