This kind of architecture style was originated from ancient Greece.

John Dalrymple was descended from an ancient Ayrshire family.

曹老师您好，我想请教您一下：

这里的“originate”和“descend”都是不及物动词，为什么字典上查到的句子也有被动用法“be originated from”和“be descended from”以及“be derived from”

之前学习中学到：不及物动词是没有被动用法。

曹老师我想请教下，这里的被动该如何理解呢。

谢谢您的回复，万分感谢！
