OG 17 CR Q549


During the earliest period of industrialization in Britain, steam engines were more expensive to build and operate than either windmills or water mills, the other practicable sources of power for factories. Yet despite their significant cost disadvantages, steam-powered factories were built in large numbers well before technical improvements brought their cost down. Furthermore, they were built even in regions where geographical conditions permitted the construction of wind- and water-powered factories close to major markets.

Which of the following, if true, most helps to explain the proliferation of steam-powered factories during the earliest period of industrialization in Britain?

A) In many areas of Britain, there were fewer steam-powered factories than wind- or water-powered factories in the earliest period of industrialization.
B) Unlike wind- or water-powered factories, steam-powered factories were fueled with coal, which sometimes had to be transported significant distances from the mine to the site of the factory.
C) It was both difficult and expensive to convert a factory from wind power or water power to steam power.
D) In the early period of industrialization, many goods sold in towns and cities could not be mass-produced in factories.
E) In Britain, the number of sites where a wind or water-powered factory could be built was insufficient to provide for all of the demand for factory-produced goods at the time.


这道题正选为E, 我选了C, 错的原因我也想通了：题目要找的是能够解释“为什么steam engines比其他两种贵，但依然被广泛采用，” 而C的漏洞是“如果不打算建steam engines, 就不会去关心日后如果convert可能要花更多钱. 如果认为steam engines比water/wind mills好日后横竖是要convert的不如现在直接建了，属于主观过度推断 - 原文没有提及steam engines的优异性，只说它也是一个practicable sources of power for factories.

E我是在看到了all of the demand那里时否定的。 因为可以建wind/water mills的那些地方 （我不知道可以建wind/water mills的regions占总regions的多少 - 无论是10%还是70%） 不能满足市面对产品的总需求不是很正常吗？如果把能建wind/water mills 的地方建wind/water mills, 剩下的地方建steam engines factory说不定就能满足所有需求了呢？


请各位指教.

结论：尽管steam engine 贵，但是还是在能够建造风力和水力发电站的地方建造了steam engine

要解释这个结论那么就要给出建造steam engine 的好处和 水力/风力的不足之处

E 满足了这个要求。我没看懂楼主对E的解释，sorry

我对E的理解是，在那些个可以建造风力和水力的地方，即便是建造了前者，它们也是无法满足那时候的所有的需求的

要解释这个结 ...

谢谢回答！应该是我的思路太奇葩了，也没说清楚.

所以我才觉得E没有回答为什么在可以建wind/water mills的地方，依然不建这两种工厂。

这个题重看今天想开了：

题目思路：解释为什么steam-powered factories 这么贵还要建? By the way, 环境限制导致只能建steam-powered factories不是原因。

E - 因为wind/water factories 不可以满足所有需求 --- 暗示：steam-factories可以 -- implication：人们建steam-factories是因为它贵得有道理

C - 如果我认为steam-factories好，值得，我一开始就要建。如果我没建，说明我觉得它不好，而water/wind factories 更好，那我又何必去担心convert的费用。


关键还是要理解作者写各个句子的意图。不要往无关的方向琢磨。
