英语语法I wasn't even aware they were still making pennies中为什么用wasn't?
I wasn't even aware they were still making pennies中为什么用一个wasn't?
句子写成I even have no awareness that they were still making pennies不行么?
句子写成I isn't even aware they were still making pennies不行么?
句子写成I havn't aware they were still making pennies可以么
原文翻译是 我都不知道还有制造这种便是的
按句子意思就是现在也不知道对吧，那为什么还要用过去式的，而不是isn't
答
后面的从句中用了were过去式 主从一致所以前面的句子中也用过去式 am的过去式为was 根据意思应用否定 所以用wasn't什么情况要主从一致？我过去不知道 现在知道了才会有这句话至于主从一致 一般情况下 主语中的谓动何从句中的谓动时态都是一致的 具体的还要放到语境中去
