(A) because many residents of the Southeast do not share the same ethnic heritage as
(B) because many residents of the Southeast do not share the same ethnic heritage with
(C) because many residents of the Southeast do not have the same ethnic heritage as
(D) due to many residents of the Southeast not sharing the same ethnic heritage with（C）
(E) whereas many residents of the Southeast do not share the same ethnic heritage as
我选的是 B。这里为什么要用have not share 呢？ 我感觉有两种意思：1。东南居民和东北居民有分享共同的文化遗产，如b所说；2。 东南居民不像东北居民那样有共同文化遗产，那就是东南居民之间没有共同文化遗产，像c所说。
不知道我的疑惑有没有说清楚，大家可以帮我解释一下使那个吗？ 我有些糊涂了，觉得两个答案差不多，就是看意思了，估计？
谢谢！ |
