The Court was still,in theory,under a duty to enquire into the facts alleged.
问题描述：
The Court was still,in theory,under a duty to enquire into the facts alleged.
The pillars that hold up the roof broke in the earthquake,leading to the collapse of the house.
请帮忙解释这两个句子,另外想问第二个句子中为何不是held up 而是原形?
改为holding可以吗？
答
从理论上讲,该法庭仍然有责任调查指称的事实.
那些托起屋顶的柱子在地震中断裂,导致房屋倒塌.
应该是 held up.不是打错了,就是印错了.
