问一个句子中的两个词Ethnologists had a distinct reason for wanting to hear the stories： they were after linguistic or anthropological data that would supplement their own field observations, and they believed that the personal stories, even of a single individual, could increase their understanding of the cultures that they had been observing from without.这里的they指代的是stories吧?那么after是什么意思呢?还有这里这个without就真是让我莫名其妙了.哪个大虾帮帮忙,不胜感激
