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？
