意群训练： A long-held view of the histor y of the English colonies that became the United State s has been tha t England's polic y toward these colonies before 1763 was dictated by commercial interests and that a change to a more imperial policy , dominated b y expansionist militarist objectives , generated the tensions that ultimately led to the American Revolution .

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

译文： 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 （向着更大程度的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。
