一道有关时态的英语选择题~Oh,it’s you.I’m sorry I _______ know you _______ here.A.don’t; are B.didn’t; areC.didn’t; were D.don’t; were这道题选C,为什么不选B呢
因为这是宾语从句,宾语从句主句时态和从句时态要一致.主句过去时,从句过去时. I _______ know you _______ here.句子中的know后面其实是省略了引导词that的,所以B肯定是错误的

因为现在我知道你在这儿了。所以我不知道要用过去式,用were here 是因为从句要和主句的时态保持一致。

句子意思是:哦,是你啊!很抱歉,我不知刚才是你在这里(言下之意,现在知道了)。那肯定前后时态保持一致了,用过去时,所以选C

前面就是过去时了后面也得是啊,这是时态一致原则~
