题目解析:
选择欧洲北方没有被南方影响到的地方。此段的前半段都是在讲北方试图向南方扩展势力,而从But这个转折开始讨论南方对于北方大的影响,可以用选项关键词在But之后的内容进行分别定为,A选项关键词为castles, B选项为education, C选项为cities, D选项为industry and trade:
1) Over the course of the twelfth century, the feudal kingdoms witnessed a proliferation of cities modeled in large degree on those of the south.
原文这句话和C选项呼应。
2)Contact with the merchants and financiers of the Mediterranean led to the development of northern industry and international trade (which helped to pay for many of the castles and cathedrals mentioned earlier).
这句话和D选项呼应。
3) And education spread as well, culminating in the foundation of what is arguably medieval Europe's greatest invention: the university.
这三点分别对应了C、D、B选项,只有A选项没有提到,因此答案为A选项。
