Human beings weren't designed to swallow emotions.
各位老师好，我想请教下:这句话还原成原句是“we design human beings to swallow their emotions.”那这句话（被动语态或主动语态）中，不定式是做什么成分呢，目的状语么？但是swallow their emotions的逻辑主语显然是human beings呀。
望各位老师指教！！万分感谢！！
be designed to do 的意思是“预定做某事”，其中的不定式表示目的。如：
This fund is designed to help refugees. 此资金专用于救助难民。
