为什么用倒装？主语过长？

主语过长，谓语过短不倒装很难看。

OG192
    

192.
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.

    

(A)            to which has been added English, Spanish, and Italian words

    

(B)            added to which is English, Spanish, and Italian words

    

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

    

(D)            with English, Spanish, and Italian words
            having been added to it

    

(E)            and, in addition, English, Spanish, and Italian
            words are added

    

            

    

The underlined section must modify the noun phrase seventeenth-century French
by noting additions made to French subsequently from foreign
vocabularies. C, the best choice, does this clearly, directly, and
correctly in the form of a relative clause.
            （从未判断部分判断，划线部分与原句的关系） Because the subject of this clause is plural (words), the verb must also be plural (have been added).
        （主谓一致）A and B incorrectly use singular forms has been added and is added. B also awkwardly inverts and divides the verb phrase (added... is). D offers an awkward adverbial construction, which cannot be used to modify nouns.
            （副词短语无法形容名词） E offers an incoherent and incomplete new clause with the wrong verb tense and no logical complement for are added that is, we are not told to what the words are added.
            （时态错，add to 是固定用法，另外另一个句子改变句意）

是不是答案改为倒装根好呢？因为主语很长

                to which have been added English, Spanish, and Italian words

(A)            to which has been added English, Spanish, and Italian words

A 的错误，只是用了has 而非have

根据OG上的解释是说A和C所表达的意思正好相反,A调整后是which has been added to  English, Spanish, and Italian words.C调整后是  English, Spanish, and Italian words have been added to which.所以根据句子的逻辑关系,选择C
