长难句翻译

难句类型：复杂修饰、插入语

A long-held view of the history of English colonies that became the United States has been that England’s policy toward these colonies before 1763 was dictated by commercial interests and that a change to a more imperial policy, dominated by expansionist militarist objectives, generated the tensions that ultimately led to the American Revolution.

一个对于后来成了美国的英国殖民地的历史的长久以来的观点，认为英国在1763年以前对于这些殖民地的政策被经济利益所支配，而且认为一种向着更大程度帝国制度的政策上的转变——为扩张主义的军事目标所左右——产生了最终导致美国革命的紧张气氛。

解释：主架构简单，可是主语和表语从句都不让人省心。句子的主干其实就是：A long-held view has been that..。但是主语A long-held view之后却是修饰它的一个三层的定语：of the history of the english colonies that became the United States。系动词has been之后所接的表语从句其实不止一个，其实原句是用了and来连接两个并列的表语从句，has been that…and has been that…。后面的has been照例被省略。
