请高手答题：roughly是副词,为什么这里用副词修饰名词one? It is work with important safety implications in an increasingly busy society,not just for shift-workers but for the roughly one in six Americans who regularly get six hours or less of sleep a night. 英语

【答案】
roughly的确是副词,含义是【几乎,大概】
但是这里roughly修饰的不是one,而是【one in six Amercians】,即【六分之一的美国人】
这里的副词roughly修饰的不是名词,二是数词,即那个【六分之一】,功能和含义十分接近【approximately】
副词并非绝对不能修饰名词的,如,It was rather a mess.里的rather.
