l know Mr Brown;we_____to each other at an international conference.
A.are introduced B.have been introduced C.were introduced D.had been introduced
A.are introduced B.have been introduced C.were introduced D.had been introduced
我觉得选C吧.时态不是特别明显,但是翻译过来是,我知道Mr Brown,我们在一次国际会议上被介绍给对方,know是一般现在时,往前推一个时态是一般过去时.不知道答案对不对.
再问： 那为什么不用现在完成时，他过去被介绍的动作对现在产生了影响，否则我就不会知道Mr Brown
再答： 现在完成时的定义是过去发生的动作持续到现在，并且对未来仍有影响，时态标志有since,so far,over the years,in the past few years,recently等等很多，但是这题没有体现，做英语选择要记住，如果没有这样的时态标志，并且可以确定过去发生过，最佳答案是一般过去时。
