请教一个关于一句英语句子的问题.不能理解句子的结构.
Such inns as there were were generally dirty and flea-ridden; the food simply local cheese accompanied by bread often twelve months old,all washed down with coarse wine.
这是新4的第三课课文里的一句话.为什么the food simply local cheese ,bread often twelve months old可以单独成为一个名词短语用.不能理解.
但希望大家能够为小弟排忧解难.
