把……置于……之中

把……置于……之中 means "place ... within ..." and follows the frame 把 A 置于 B 之中. Use it when you need to place an object within a larger context or framework for understanding. These are formal written patterns, so keep the fixed parts complete and do not replace them with casual spoken wording. Pay attention to the relation: placement in a context, inclusion in a system, transformation, passive evaluation, inevitable result, a following consequence, or an analytical frame. Common mistakes include dropping 为, 作, 以, 地, 的是, 之中/之上, or using a similar expression with a different logical focus.
