5"Most people would agree that buildings represent a valuable record of any society’s past, but controversy arises when old buildings stand on ground that modern planners feel could be better used for modern purposes. In such situations, modern development should be given precedence over the preservation of historic buildings so that contemporary needs can be served."
很多人认为建筑代表了一个社会过去的历史价值，但是当现代城市的规划者想要利用老建筑占用的地盘做新的规划时，就会引起很多争辩。在这样的情况下，现代的发展应该优先被考虑，以使当代的需要得到满足。
6"History teaches us only one thing: knowing about the past cannot help people to make important decisions today."
7."So much is new and complex today that looking back for an understanding of the past provides little guidance for living in the present."
现在的生活日新月异，对过去的研究学习没有实际的指导意义
8."The study of history has value only to the extent that it is relevant to our daily lives."
只有当历史和我们的生活相关时，对它的研究才有扩展性和价值
