题目内容
9.He has taught English here since he ______ to the countryside.( )| A. | came | B. | has come | C. | has been |
分析 自从他来到乡下他一直在这教英语.
解答 答案:A
分析句子结构可知该句为含有since引导的时间状语从句的复合句,表示从过去某个时间开始这个动作一直持续到现在,故该句理解为"自从他来到乡下他一直在这教英语.".其中主句为现在完成时态,since引导的状语从句的谓语动词是一般过去时,故填入come的过去式came,故选A
点评 本题考查了动词的时态.做题时,一定要特别关注有关的时间短语,这是判断句子时态的标志.在没有时间状语的情况下可以联系上下文根据语境来做出正确判断
