The entire town of Delta was closed down by the goverment authourities ,after testing confirmed that the toun had been poisoned .这句句话中，“testing confirmed ”是何用法？其主语是谁？town ？testing confirmed ”是何用法？其主语是谁？testing 是何用法？

testing这儿是名词，就是主语呀！confirmed是谓语动词！that the town had been poisoned 是confirmed的宾语从句！意思是“检验结果确认这个小镇已被有毒物质污染了”！
