However little known （the feelings or views of such a man may be on his first entering a neighbourhood） ,this truth is so well fixed in the minds of the surrouding families ,（that he is considered as the rightful property of some one or other of their daughters）.
这句话的主句是this truth is so well fixed in the minds of the surrouding families ,主句的谓语动词是is.
前半句However little known the feelings or views of such a man may be on his first entering a neighbourhood中,however是副词不用管,little也是副词,known是过去分词,过去分词作状语表伴随,known后面省略了一个引导宾语从句的that,所以原句应该是However little known （that the feelings or views of such a man may be on his first entering a neighbourhood ）.
后半句that he is considered as the rightful property of some one or other of their daughters中,that是和主句中的so搭配的,so…that…,如此……以致…….请问 little known the feelings or views of such a man may be on his first entering a neighbourhood.是什么意思？谢谢~尽管不知道这样一个男人第一次拜访邻里的感受和想法这是傲慢与偏见里的吧，前一段有事一直没回复，不好意思啊，希望对你有帮助。
