1、2022年考博英语-重庆大学考试题库及全真模拟冲刺卷（附答案带详解）1. 填空题THE IRON BRIDGEThe Iron Bridge was the first of as kind in Europe and is universally recognized as a symbol of the Industrial Revolution.A: The Iron Bridge crosses the River Severn in Coalbrookdale, in the west of England. It was the first cast-iron bridge to
2、be successfully erected, and the first large cast-iron structure of the industrial age in Europe, although the Chinese were expert iron-casters many centuries earlier.B: Rivers used to the equivalent of todays motorways, in that they were extensively used for transportation. The River Severn, which
3、starts its life on the Welsh mountains and eventually enters the sea between Cardiff and Bristol, is the longest navigable river in Britain. It was ideal for transportation purpose, and special boats were built to navigate the waters. By the middle of the eighteenth century, the Severn was one of th
4、e busiest rivers in Europe. Local goods, including coal, iron products, wool, grain and cider, were sent by river. Among the goods coming upstream were luxuries such as sugar, tea, coffee and wine. In places, the riverbanks were lined with wharves and the river was often crowded with boats loading o
5、r unloading.C: In 1638, Basil Brooke patented a steel-making process and built a furnace at Coalbrookdale. This later became the property of Abraham Darby (referred to as Abraham Darby Ito distinguish him from his son and grandson of the same name.) After serving an apprenticeship in Birmingham, Dar
6、by had started a business in Bristol, but he moved to Coalbrookdale in 1710 with an idea that coke derived from coal could provide a more economical alternative to charcoal as a fuel for iron making. This led to cheaper, more efficient iron making from the abundant supplies of coal, iron and limesto
7、ne in the area.D: His son, Abraham Darby II, pioneered the manufacture of cast iron, and had the idea of building a bridge over the Severn, as ferrying stores of all kinds across the river, particularly the large quantities of fuel for the furnaces at Coalbrookdale and other surrounding ironworks, i
8、nvolved considerable expense and delay. However, it was his son Abraham Darby III (born in 1750) who, in 1775, organized a meeting to plan the building of a bridge. This was designed by a local architect, Thomas Pritchard, who had the idea of constructing it of iron.E: Sections were cast during the
9、winter of 1778-9 for a 7-metre-wide bridge with a span of 31 metres, 12 metres above the river. Construction took three months during the summer of 1779, and remarkably, nobody was injured during the construction process- a feat almost unheard of even in modern major civil engineering projects. Work
10、 on the approach roads continued for another two years, and the bridge was opened to traffic in 1781 Abraham Darby funded the bridge by commissioning paintings and engravings, but he lost a lot on the project, which had cost nearly double the estimate, and he died leaving massive larger debts in 178
11、9, aged only 39. The district did not flourish for much 1onger, and during the nineteenth and early twentieth centuries factories closed down. Since 1934 the bridge has been open only to pedestrians. Universally recognized as the symbol of the Industrial Revolution, the Iron Bridge now stands at the
12、 heart of the Iron Bridge Gorge World Heritage Site.F: It has always been a mystery how the bridge was built. Despite its pioneering technology no eye-witness accounts are known which describe the iron bridge being erected and certainly no plans have survived. However, recent discoveries, research a
13、nd experiments have shed new light on exactly how it was built, challenging the assumptions of recent decades. In 1997 a small water colour sketch by Elias Martin came to light in the Swedish capital, Stockholm. Although there is a wealth of early views of the bridge by numerous artists, this is the
14、 only one which actually shows it under construction.G: Up until recently it had been assumed that the bridge had been built from both banks, with the inner supports tilted across the river. This would have allowed river traffic to continue unimpeded during construction. But the picture clearly show
15、s sections of the bridge being raised from a barge in the river. It contradicted everything historians had assumed about the bridge, and it was even considered that the picture could have been a fake as no other had come to light. So in 2001 a half-scale model of the bridge was built, in order to se
16、e if it could have been constructed in the way depicted in the water colour. Meanwhile, a detailed archaeological, historical and photographic survey was done by the Iron bridge Gorge Museum Trust, along with a 3D CAD (computeraided design) model by English Heritage.H: The results tell us a lot more about how the bridge was built. We now know that all the large castings were made individually as they are all slightly different. The bridge wasnt welded or bolted toge
