导读

托福考试涵盖文章内容范围广，之前我们为大家爱分享过生物类、地理类甚至经济类的文章，本期呢，我们为大家分享一篇社科类的文章。

托福阅读的文章涵盖范围非常广，复杂的专业知识，艰涩的学科词汇让很多同学头疼。今天我们就几个题来把握一下社会科学方面的问题，掌握一些社科类的词汇。

社科类词汇相对于地质，生物类词汇而言，相对常见，也更容易识背。同学们课下一是可以通过词汇书以及词汇资料去积累记忆，第二就是及时进行文章精读，归纳整理。

我们今天就一篇阅读部分社科类文章进行讲解，希望大家能积累一些地社科词汇，掌握做题方法。

Two other developments presaged the end of the era of turnpikes and started a transportation revolution that resulted in increased regional specialization and the growth of a national market economy. First came the steamboat; although flatboats and keelboats continued to be important until the 1850’s steamboats eventually superseded all other craft in the carrying of passengers and freight. Steamboats were not only faster but also transported upriver freight for about one tenth of what it had previously cost on hand-propelled keelboats. Next came the Erie Canal, an enormous project in its day, spanning about 350 miles. After the canal went into operation, the cost per mile of transporting a ton of freight from Buffalo to New York City declined from nearly 20 cents to less than 1 cent. Eventually, the western states diverted much of their produce from the rivers to the Erie Canal, a shorter route to eastern markets.

Paragraph 5 mentions that the Erie Canal led to a reduction in all of the following EXCEPT

A.the length of the route that goods from the West traveled across to reach eastern markets.

B.the cost of transporting freight.

C.the price of produce from western states.

D.the amount of produce from western states that was shipped on rivers.

根据题干我们知道，这是一道细节选非题，题干问第五段中Erie运河并没有导致四个选项中哪个的减少。我们需要在文章中运河的建成导致了什么的下降，文章未提及的即答案。我们拿Erie Canal定位到了Next came the Erie Canal，往后看我们发现，1.the cost per mile of transporting a ton of freight declined，即运输每吨货物的价格减少，即对应选项B，运输的花费减少，2. the western states diverted much of their produce from the rivers to the Erie Canal西方国家转移很多产品从河道到运河，即对应选项D，由经过河流运输的货物减少。3. the Erie Canal, a shorter route to eastern markets，运河即通往东方世界更短的路线，即对应选项A，从西方运往都东方的路径长度减少。因此，该题选C，西方世界产品的价格并未提及。
