问题：新概念3里第二课的一个问题Armedwithatorch,the 
Arm with a torch, the vicar went up into the clock tower to see what was going on.这里armed with 与 主语vicar 应该是主动关系啊， 牧师拿着手电筒， 为什么用被动？麻烦高手给我这个菜鸟讲解一下～谢谢了～！！ 
回答：armed with
用...武装起来, 装备有...的

arm
vt., vi.
武装; 装备
arm oneself against danger
武装起来, 对付危险
armed to the teeth
武装到牙齿; 全副武装

arm和vicar是动宾关系，所以用被动。

补充：
我再把分词作状语的形成过程推导一下
The vicar was armed with a torch.+ The vicar went up into the clock tower to see what was going on.
去掉The vicar was，合成一句：
Armed with a torch, the vicar went up into the clock tower to see what was going on.
也即分词作状语
