原文：
Yet the critical campaign I pondered did not take place, partly because of external hindrances, but also because of my intervening doubt. In fact, the Head Juries were rather well suited to the most recent cultural viewpoints and interrelationships of human activities. There could have been no other plan devised for the general Industrial Exhibitions of 1851.

参考答案：

然而我所认为的关键性措施并未被采取，部分是由于客观原因，但部分也是由于我在两者间的犹豫。事实上，“首席评审委员会原则”更符合最近的文化观点以及人类活动的相互影响。再也找不到为了1851年这种综合性工业博览会而设计的其它计划了。
