题目解析：
本题为否定事实信息题，根据选项中的关键词，回原文定位，用排除法得出答案。
A选项关键词“waterways”,我们找到原文中和水道相关的这句话 “Moscow has the rare fortune of being located near the headwaters of four major rivers: the Oka, the Volga, the Don, and the Dnieper.”意思是“莫斯科极其幸运地坐落在奥卡河、伏尔加河、顿河及第聂伯河这四条主要河流的源头附近。”因此A选项符合原文，故排除。
B选项说莫斯科周围都是开阔地带，定位到本段最后一句“This offered marvelous opportunities for expansion across the flowing plain, especially as there were no mountains or other natural obstacles to hem in the young principality.”这句话说明莫斯科周围没有群山和自然障碍，地处平原地带，故B选项符合原文，排除。
C选项说莫斯科位于道路交叉口。定位到这一句“Moscow lay as a crossing of three roads.”，C选项完全符合原文，故排除。
D选项说莫斯科因地处河湾地带而免受侵略，在这一段中只提到河流能促进莫斯科经济发展，并没有提到河流抵御外敌的作用，故D选项原文未提及，为正确答案。
First, attention may be given to the doctrine of geographic causation. It stresses the decisive importance of the location on Moscow for the later expansion of the Muscovite state (the medieval state centered in Moscow) and includes several lines of argument. Moscow lay as a crossing of three roads. The most important was the way from the historically crucial city of Kiev and the declining south to the growing northeast. In fact Moscow has been described as the first stopping and setting point in the northeast. But it also profited from moments in other directions, including the reverse. Thus it seems immigrants came to Moscow after the Mongol devastation of the lands further to the northeast. Moscow was also situated on a bend of the Moscow River that flows from the northwest to the southeast into the Oka, the largest western tributary of the Volga River. To speak more broadly of water communications which span and unite European Russia, Moscow has the rare fortune of being located near the headwaters of four major rivers: the Oka, the Volga, the Don, and the Dnieper. This offered marvelous opportunities for expansion across the flowing plain, especially as there were no mountains or other natural obstacles to hem in the young principality.
