8.By the end of last year,another new teaching building in our school.( )A. | would be completed | B. | had been completed | ||
C. | was being completed | D. | have been completed |
分析 直到去年底,另一栋新的教学楼被建好了.
解答 答案:B.
由时间状语By the end of last year可知,这是过去完成时态的标志,教学楼是被建,所以是被动语态,过去完成时态的被动语态结构:主语+had been+过去分词;故选B.
点评 过去完成时态表示过去的过去,时间状语是过去的参照时间.和现在完成时态不同的是,现在完成时态的参照时间是现在.学习时,要注意区分.
