题目内容：

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？

优质解答

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.
