英语翻译
Often this earliest form of advertising involved a newly arrived ship loaded with goods.
这是一篇说广告起源的文章,这个句子是抽出来的一句,觉得有点晕.
请分析句子结构,然后标准翻译,

主语 this earliest form of advertising
谓语动词 involved
宾语 a newly arrived ship
定语 loaded with goods （修饰ship）
状语 often
这种最早的广告形式往往涉及一艘满载货物刚刚抵港的船.
如果要照顾上下文,采用意译较好：
每当有满载货物的船只抵达,这种广告雏形就派上用场了.
