when _____(present) with a common case, sales managers tend to see sales problems and production managers see production problems.
答案是presented.既然有when这个连词了,说明应该是从句,那么present应该是谓语动词了,为什么还要用非谓语动词的分词呢?

这么对你说吧
时间状语从句中,当主句和从句的主语一致(在这里都是sales managers ),而且从句的谓语是BE动词,可以省略从句的主语和BE动词,在这里就是省略的sales managers was
其实完整的句子是这样的:when the sales managers was presented with a common case, sales managers tend to see sales problems and production managers see production problems

好深奥
