Question

希望能帮忙解答一下，非常感谢！

Darcy was divided between admiration of the brilliant which exercise had given to her complexion, and doubt as to the occasion's justifying her coming so far alone.(这段话伊丽莎白去Netherfield看望生病的姐姐Jane ，达西先生在餐厅迎接她时的内心想法。)这句话中的as to the occasion's justifying her coming so far alone这句话怎么解释啊？尤其是as to the occasion's justifying ，是什么用法啊？

Answer 1

was divided between admiration of the brilliancy which exercise had given to her complexion, and doubt as to the occasion's justifying her coming so far alone

was divided between admiration... and doubt...在欣赏与怀疑（两种情感）之间摇摆

admiration of the brilliancy which exercise had given to her complexion
翻译：对运动给她的皮肤带来的亮泽的欣赏

doubt as to the occasion's justifying her coming so far alone
as to: with regard to 关于，是个介词词组，后面接名词性成分，这里接了个名词occasion加动名词justiying...作补语
justify sth 给某事充分的理由
the occasion指的是她姐姐生病的这件事
翻译：对于这件事作为她独自走这么远的路程的充足理由的怀疑，
也就是说：怀疑Liz为了这件事就自走这么远的路程是不是有必要
