we hurried to the station only to find ourselves three hours earlier for the train

we hurried to the station only to find ourselves three hours earlier for the train
我们匆忙的赶到火车站,结果却发现我们比火车早到了三个小时ourselves three hours earlier for the train这句话我觉得是 主语+表语 少了个系动词是的难道 three hours earlier 被看做一个整体 用物主代词可以直接连接？后半句主语是we 谓语是find ourselves宾语，后面是修饰成分没有表语的（表语是跟在be动词后面的）we find him two hours earlier for the train. 主谓宾宾？对啊反正是没有表语的
