题目内容
12．-_____ you _____ your homework yet？-Yes．I _____ it ten minutes ago．（ ）
| A． | Did，do； finished | B． | Have，done；finished | ||
| C． | Have，done； have finished | D． | Will，do； finished |
分析 --你完成你的作业了吗？
--是的，我十分钟之前就完成了．
解答 答案：B．
根据yet，可知这里的意思是还、尚、迄今、到那时，一般用于现在完成时的一般疑问句中，现在完成时态的结构为have/has+动词的过去分词，再根据yesterday，可知答句应该用一般过去时，这里用finish的过去式形式finished，故选B．
点评 本题主要考查现在完成时，用法：表示过去发生或完成的动作对现在造成的影响或结果，还表示过去发生动作一直持续到现在．其结构是have/has+及物动词的过去分词．
