同学们做题的时候时常因为理解的不准确，而导致答案错误，尤其是一些隐含的意思，需要经过头脑的推理才能作出正确的解答。否则会出现学生振振有词觉得自己是对的，还给得出理由。今天我们一起来看看今天的内容：tpo33阅读第二篇真题+解析吧！
The new railroad networks shifted the direction of western trade. In 1840 most northwestern grain was shipped south down the Mississippi River to the bustling port of New Orleans. But low water made steamboat travel hazardous in summer, and ice shut down traffic in winter. Products such as lard, tallow, and cheese quickly spoiled if stored in New Orleans‟ hot and humid warehouses. Increasingly, traffic from the Midwest flowed west to east, over the new rail lines. Chicago became the region‟s hub, linking the farms of the upper Midwest to New York and other eastern cities by more than 2,000 miles of track in 1855. Thus while the value of goods shipped by river to New Orleans continued to increase, the South‟s overall share of western trade dropped dramatically.
5. According to paragraph 3, what was a disadvantage of shipping goods from
northwestern areas to New Orleans?
A. There was no reliable way to get goods from New Orleans to eastern cities.
B. The cost of shipping goods by river to New Orleans continued to increase.
C. Goods shipped from New Orleans‟ neighboring areas had a significant
competitive advantage because of their lower transportation costs.
D. The temperatures and humidity.
答案 B
解析 细节题: Thus while the value of goods shipped by river to New Orleans
continued to increase, the South‟s overall share of western trade dropped
dramatically. 意思是说因为虽然货物本身的价值在增加, 但是南部的市场
份额却在下降, 就暗示了越来越少人的人愿意通过该途径运货, 即要么速
度太慢要么成本太高。
问题讨论：
学生：我选的是D ，原文明明有说Products such as lard, tallow, and cheese quickly spoiled if stored in New Orleans‟ hot and humid warehouses. 所以temperature和humidity是很明显的disadvantage啊，为什么要选那么隐晦的B??
老师：因为问题是what was a disadvantage of shipping goods from northwestern areas to New Orleans 意思是在从西北 到 New Orleans 运输过程的disadvantage, 而D选项讲的是到了New后储存的缺陷(...if stored in New Orleans‟ ). B选项在“Thus while the value of goods shipped by river to New Orleans continued to increase”中有体现， 就是运输的费用keep increasing
value of goods 和 cost of shipping goods是两个不同的概念
