问一个英语语法问题,详细内容见补充.
句子是这样的Rumors,embroidered wiht detail,live on for years,neither denied nor confirmed,until they become accepted as fact even among people not known for their credulity.我想问问为什么最后一句的not修饰的不是known 而是crdulity,

not known for their credulity.这是过去分词短语作定语 以不轻信而闻名的=不是以轻信而闻名的
否定词 只能 放在 过去分词 前面
这就像 i can't speak english well一样 否定的是副词 well
总之 这只是 翻译问题
