18. with respect to 关于，至于，谈到
without respect to 不管，不顾
比较 with respect to VS regarding
with respect to比较正式，经常用于商务文稿中。在英式英语中，还可以说in respect of，后者更加正式。
相比而言，regarding的正式程度略微低些，口语中也经常说。当然，同源的词，更正式的用法还可以用with/in regard to，以及in this/that regard。
以上是基本理解。用法上还是观察体会出一点细微区别。如下例句：
With respect to your inquiry, I enclose an explanatory leaflet.
He refused to divulge any information regarding the man's whereabouts.
实际上在使用中，前者多用于With respect to sth, + 主句这样的结构。因为正式的文体中主句一般比较长，将该短语前置可以使句子比较平衡。通?？梢胛汗赜谀呈挛?就某方面而言，+主句内容。
而后者多用于中心词 + regarding sth这样的结构。语义不会太复杂，一般可译为关于...(sth)的...（中心词）。
想起群里讨论，整理如下：
to some degree/ to some extent ?在一定程度上
degree 程度水平 extent 应用面积,范畴
to the extent ? ?在某种程度上 # To the extent they'd seen them, they'd seen them in the movies.即使见到，也是在电影里。
to the degree （较少用）到···程度 # He knows the place to the degree that he can find any landmark with his eyes closed.
