选择恰当的语法结构能显著提升句子的信息密度和逻辑性，以下对比展示不同句式处理方式的效果差异：
原始表达：The situation that resulted in my grandfather's not being able to study engineering was that his father needed help on the farm.
优化版本：My grandfather couldn't study engineering due to his father's farm labor demands.
原被动句式：In the fall, not only did the cows have to be milked, but also the hay was mowed and stacked by my grandfather's family.
主动语态优化：During autumn harvests, my grandfather's family managed both dairy operations and hay processing.
通过删除冗余修饰语和合并相关信息，实现单位文本信息量的有效提升：
原始段落：Dairy cows were raised on the farm, which was located 100 kilometers from the nearest university and was in an area that was remote.
优化表达：The remote dairy farm, situated 100km from academic institutions, required full family commitment.
