英语问题they would turn up their noses at a bar or two
Most economists hate gold.【 Not,you understand,that they would turn up their noses at a bar or two.】
我看到括号里这句话的翻译是：要知道这可不是因为他们瞧不起一两块黄金
我想问下,括号里这句话是什么机构和句式啊.不懂啊,还有后面的什么turn up their noses 是不是谚语啊,是鄙视轻视的意思么,因为把鼻子都翻上去了?

Answer 1

来自not that...but that...不是……而是……
Not that I dislike her,but that I have no time.
并不是我不喜欢她,而是我没有工夫.
you understand是插入语.
