A. so many people have been moving to Utah such that Mormons who were once 75 percent of population are now only accounting for half of it
B. many people have been moving to Utah, so Mormons once 75 percent of the population are now accounting for only half
C. that many people have been moving to Utah, such that the Mormons that were once 75 percent of the population are now accounting for only half of it
D. many people have been moving to Utah such that the Mormons, who once represented 75 percent of the population, now only account for half
E. so many people have been moving to Utah that the Mormons, who once represented 75 percent of the population, now account for only half E
这个题目肯定是选择E的 所以不能算争议题
这里有几个概念多说两句，用系动词连接的结构 即 主 系 表 结构 如果主语和表语都是名词 那么这两个名词必须要“可比”，或者说要能联系在一起
A选项里面 Mormons were 75% population这个主系表结构就是不对的，因为Mormons应该是一种人 它不能是人口，而E选项的表达则是正确的 它采用了represent和account for来连接两个名词 A的另外一个错误是so ... such that，这种表达是不符合习惯表达的，so 和such that里面有重复的意思，所以such 应该去掉
B选项里面将原句的so that从句（这个是状语从句）改为了so引导的并列句，这个是不好的，或者说文章并没有明确的标志要表达两者的并列意思，应该是that 从句所引导的意思是为了强调前面的 so many people have been moving这个动作的，所以就应该使用状语 而不应该使用并列句；同时so后面的句子也很奇怪，Mormons 75% of population 这两个名词性词汇放在一起可以有两种解释，一种是Mormons的75%人口，另一种是75%那个结构最为插入语，但是插入语通常需要用逗号隔开。
C这个选项句子结构不完整，前面是一个that引导的主语从句 后面such that作为状语从句，整个句子没有谓语动词 ，其他的毛病就不说了
D这个选项的错误不明显，或许真正的争议在D和E之间，在我看来呢D是没有任何语法错误的 但是：
首先原句中的so manny结构被打破 成为了 many such that这个结构，这个结构语法正确，意思却稍微有点改变，原句中强调了many 但是现在这个句子是把整个主句都作为原因，
其次only的位置从only account 变成了only half这个结构上的变化也是很蹊跷的，简单说之前的only修饰动词account 但是D中的only则修饰half
由此 E是最佳答案 希望这样的解释能够帮到你 |
