in employee illness prevention and gain as much as $200 billion through improving performance of workers if they simply provided
by preventing illness among employees and gain as much as $200 billion through improved worker performance if they simply provided
each year和annually意思重复
by、through代表通过的意思，and前后需要出现by或through来保持平行
by doing sth／through sth
choice d, in employee illness prevention改变了句子的意思，变成了在预防员工疾病这件事情上可以省下钱。相当于今年在员工疾病预防上花的钱比去年在员工疾病预防上花的钱减少了58 billion。
choice e, by preventing illness方式状语表达的意思是通过预防疾病，公司可以省下58 billion。correct
de之间选错，
D: save money in employee illness prevention 在员工疾病预防方面省钱（少花钱给员工疾病预防）
E: save money by preventing illness among employees 通过预防员工之间的疾病省钱
each year 和anually重复
没注意到each year 和 anually重复。错选A，they指代不明
each year 与 annually 重复，比较选项间的不同也是必要的
D save money in sth (从某处省钱) 和 save money by sth （通过某处省钱）
D: save money in employee illness prevention 在员工疾病预防方面省钱
E: save money by preventing illness among employees 通过预防员工之间的疾病省钱
each year 与 annually 重复
D的improving performance - 只能把improving看成动名词，因为句首doing很少做adj。 应该是通过核心词"performance" 而不是"提高" 来赚钱，所以选E。
通过预防疾病这件事节约成本，而不是在疾病的预防里节约成本
题干有each year首先排除ABC, 和annually赘余。D中through improving performance of workers 可理解为伴随状语连词+ving，所以逻辑主语是companies in the US，但是提高工人的表现不是公司，而是比如说高科技啥的，所以D不对。E中through improved worker performance不存在这个问题。D中in employee illness prevention是状语，在预防疾病方面也讲的通，E中是by preventing illness among employees也是状语，逻辑主语companies也可以讲的通，所以我认为这不是考察的点。不知道我的理解对不对？
D，workers和companies都有可能是they的指代对象，有歧义
E，they只能指代companies，没有歧义，更优
主要考点：redundancy、平行
语义：companies通过某种方式做到省钱和赚钱
语法：
ABC选项：通过观察选项发现，多出annually，此处为redundancy错误，因为开头已经有each year。排除；
D选项：原句合理句意为companies通过某种方式做到省钱和赚钱。对比E发现，by和through有通过某种方式的意思，D选少了by，不平行。排除
a的annually和each year重复！
annually和each year有重复的嫌疑！
annuall 和 each year 重复语义 排除abc ， d语义错误不是在防治上省钱，而是通过防治省钱
save ¥50 in prevention 语义错 prevention不能用金钱衡量
each year和annually重复！
D感觉和原文说的不是一个意思了 D说的是在员工疾病防御上可以赚很多钱
E说的是可以通过防止员工生病赚钱
each year 和annually重复冗余！！！！！！
