1. Cajuns speak a dialect brought to southern Louisiana by the 4,000 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

OA是C， 我的问题是C中的Have been 能改成现在时吗？能反映一个general truth吗？为什么一定是现在完成时？

不可以用一般现在时，add to已经完成，不再继续，现在或将来这个动作不再有了。

动作发生在过去，强调对现在的影响，表示一个持续完成的动作，所以要用现在完成时。

不可以。

因为现在完成时表示动作已完成，且对现在造成影响；
现在时只是动作发生在现在，和过去无关。

dialect已经在过去形成，并且对现在有影响（仍在使用中）。
