题目

问一下关于这几个句子的语法问题
Recently implemented "shift-work equations" based on studies of the human sleep cycle have reduced sickness,sleeping on the job,【fatigue among shift workers,and raised】production efficiency in various industries
括号中的句子有什么问题呢?为什么要改为“and fatigue among shift workers while raising"呢?它们之间有转折关系么?
Spanning more than fifty years,Friedrich 【Miiller had begun his career with the unpromising apprenticeship of being 】 a Sanskrit scholar and culminated in virtually every honor that European governments and learned societies could bestow.
括号内的句子为什么要改为" Miller's career began in an unpromising apprenticeship as" 原文有什么不妥么?
The coast Guard is conducting tests【 to see if pigeons can be trained for helping to find】 survivors of wrecks at sea.
括号中的句子用法有不对的地方么?为什么要改成" to see whether pigeons can be trained to help find "呢?原句中的be trained for 是不对的吗?
顺便再问一下 interaction 后跟of 还是between 如果都可以的话那分别是什么意思呢?
