请问这段英语里两个动词 were fired ; met our challenge 为什么用过去式
RONALD REAGAN:"If I could just take a moment,I had an assignment the other day.Someone asked me to write a letter for a time capsule that is going to opened in Los Angeles a hundred years from now.
"We live in a world in which the great powers have poised and aimed at each other horrible missiles of destruction,nuclear weapons that can in a matter of minutes arrive at each other's country and destroy virtually the civilized world we live in.
"And suddenly it dawned on me; those who would read this letter a hundred years from now will know whether those missiles were fired.They will know whether we met our challenge.Whether they have the freedoms that we have known up until now will depend on what we do here.Mister President..." [Cheering]

those who would read this letter a hundred years from now will know whether those missiles were fired.
这里用的虚拟语气,必须用过去时态表示.表示假使这种情况的发生会明白那些导弹是否被发射.
whether those missiles were fired.They will know whether we met our challenge.
紧接着下面的这个whether跟前面的whether表达同样的意思,所以同样用过去时态表示虚拟,即使的情况.这种事情并未发生,只是假使的情况.
