初三英语（单选）
did you watch TV this morning?the lost child ____last night
标准答案是was found.但为什么不能填has been found或had been found
能讲一下一般过去时,现在完成时和过去完成时的区别,标志性词语分别是那些?

现在完成时have done往往表示过去的某一动作持续到现在并对现在有影响,但是这里的昨晚找到小孩的动作只是一个单纯的过去的动作,小孩找到了,动作也结束了,而且这里有last night 为证,没有延续的意思.如果句子说失踪的小孩到现在一直没找到,那么就可以说：The lost child has not been found until now.因为小孩从失踪到现在一直没被找到,动作还在持续中.
不知道我是否说清楚了,但愿能帮上你.
