The technology of the North American colonies did not differ strikingly from that of Europe, but in one respect, the colonists enjoyed a great advantage. Especially by comparison with Britain, Americans had a wonderfully plentiful supply of wood.
The first colonists did not, as many people imagine, find an entire continent covered by a continuous forest. Even along the Atlantic seaboard, the forest was broken at many points. Nevertheless, all sorts of fine trees abounded, and through the early colonial period, those who pushed westward encountered new forests. By the end of the colonial era, the price of wood had risen slightly in eastern cities, but wood was still extremely abundant.
The availability of wood brought advantages that have seldom been appreciated. Wood was a foundation of the economy. Houses and all manner of buildings were made of wood to a degree un known in Britain. Secondly, wood was used as a fuel for heating and cooking. Thirdly, it was used as the source of important industrial compounds, such as potash, an industrial alkali; char coal, a component of gunpowder, and tannic acid, used for tanning leather.
The supply of wood conferred advantages but had some negative aspects as well. Iron at that time was produced by heating iron ore With charcoal. Because Britain was so stripped of trees, she was unable to exploit her rich iron mines. But the American colonies had both iron ore and wood; iron production was encouraged and became successful. However, when Britain developed coke smelting, the colonies did not follow suit because they had plenty of wood and besides, charcoal iron was stronger than coke iron. Coke smelting led to technological innovations and was linked to the emergence of the Industrial Revolution. In the early nineteenth century, the former colonies lagged behind Britain in industrial development because their supply of wood led them to cling to charcoal iron.
Why was the use of coke smelting advantageous according to the text?
选项
A、It led to advances in technology.
B、It stimulated the demand for wood.
C、It was less expensive than wood smelting.
D、It produced a stronger type of iron than charcoal smelting.
答案
A
解析
细节题。题干意为“根据文章,为什么焦炭冶炼是优越的?”根据“Coke smelting led to technological innovations...”可以知道,焦炭冶炼推进了科技发展,而其他选项都是不正确的,故A正确。
