关于with不能做副词修饰名词的解释，求帮助

with短语作副词时不可以修饰名词，

　　例如og192. Cajuns speak a dialect brought to southern Louisiana by the four thousand Acadians who migrated there in 1755; their language is basically seventeenth-century French to which has been added English. Spanish. and Italian words.

　　(C)to which English, Spanish, and Italian words have been added(正确答案)

　　(D)with English, Spanish, and Italian words having been added to it (with短语作副词时不可以修饰名词。此外，having done永远不可以做后置定语修饰名词!这条可以作为绝对错误原则，排除选项!)

我没看懂，

（1）什么叫with结构做副词？ clause也有词性？还是说  xxxxx French with English words being added, 这样不能用，因为added with French是错的，要用added to， 这个意思吗？
