　　为什么会有这样两种表达(来自新概念第三层文章）Armedwithatorch.Lookingathis

　　Lookingathiswatch,hesawthatitwasoneo'clock,butthebellstruckthirteentimesbeforeitstopped.Armedwithatorch,thevicarwentupintotheclocktowertoseewhatwasgoingon.

　　Lookingathiswatch是vicar自己主动的动作,所以是用动名词,这我可以理解.

　　但我认为Armedwithatorch也是vicar自己主动的动作,为什么要用ed形式呢?

　　下面附上全部原文
