【答案】 再如：The bridge was begun five years ago and the estimated cost has already doubled.
建筑物动工这个概念,都用sth was begun
类似的我们可以说The bridge was started 5yrs ago.
当然一般begin用主动
如：
The film they want to watch begins at seven.
The meeting began promisingly,but then things started to go wrong.
电影开始,会议开始都是主动
但比较下就知道,桥梁不是开始,而是动工,所以被动
