New York City had a deeper harbor than other Atlantic seaports was one reason for its prosperity during the early 19th century.
参考答案:错
解析:
[分析]: 因果关系的找寻和判断。 根据原文It allowed settlers in the Great Lakes region to send their crops eastward to New York City at the mouth of Hudson at a much lower cost.From there,crops could be shipped to other Atlantic ports可知,当时大湖区的定居者们将谷物经水道东运至Hudson河口的纽约城,其运费比其它方式便宜许多。在那里,货物再用船运到大西洋沿岸其它港口。由此可推断,纽约城繁荣的原因应该是因为该地是货物的集散地。而题干说纽约城有比其它大西洋诸港都深的港口在原文中并未提到,因此题干的说法是错误的。[解题关键] 正确理解语句含义并作出正确的推断是解题的关键。
