[讨论]XDF P293-17

yuguanglais

17.　An attempt to ratify the Equal Rights Amendment, begun almost two decades ago, has been unsuccessful despite efforts by many important groups, including the National Organization for Women.

答案A

提问：

begun过去分词作状语，表示被动。记忆中begin没有被动的。为什么这里可以？

看动作的发出者，决定主被动.

还是不很明白:

an attempt began almost 2 decades ago. 

an attempt was begun almost 2 decades ago.

本人觉得主动很顺, 反而被动, 怪怪的, 被开始吗?.....

请教高手指点.

同样遇到该问题了，顶一下。记忆中未遇到过begin用被动的，查字典例句也是用主动的：1. Building began last year.  2. The new fare will be 1, beginning (from) next month.  万一在以后考题里遇到，究竟用主动还是被动呢？
