The workers who gets a promotion, the student whose grades improve, the foreigner who learns a new language-all these are examples of people who have measurable results to show for their efforts.
请问：
为何不是 are improved？
to show 修饰的是什么？我感觉是 people，由于 results 应该用 shown。

请问：
为何不是 are improved？
【答】improve 可与物，也可以不及物，所以用主动语态或者被动语态均可。
to show 修饰的是什么？我感觉是 people，由于 results 应该用 shown。
【答】我把句子简化一下：people have measurable results to show
1. 意思是：大家有可以衡量的结果去展示
2. 不定式show 的逻辑主语是people；逻辑宾语是measurable results。
3. 该结构在英语中比比皆是，比如： I have a lot of work to do today.
