你好,此处的had traveled是一个过去完成时态,此句中had never traveled(从未旅行过)这个动作是发生在句中的was very excited(非常兴奋)这个过去的动作之前,即出现了“过去的过去”这个标志,所以才用到了过去完成时态
过去完成时态的用法要点:
1.当某动作发生在过去的某个动作之前时,则此动作就可以用过去完成时态了,即用过去完成时态一定要出现“过去的过去”
2.过去完成时态的结构:had+动词的过去分词/had+Ved
句子翻译是:Sally非常兴奋因为她从未坐火车旅行过
祝你开心
望采纳谢谢

这是过去完成时,表示过去的过去,即过去某一时刻之前就已经完成的动作
结构为: had + 过去分词
e.g. When he arrived at the station, the train had left.
By the end of last term, they had learned 3,000 words.
