2022年考博英语-辽宁大学考试内容及全真模拟冲刺卷（附带答案与详解）1. 单选题Standing on the rim of the Grand Canyon, gazing across this giant wound in the Earths surface, a visitor might assume that the canyon had been caused by some ancient convulsion. In fact, the events that produced the canyon, far from being sudden and cataclysmic, simply add up to the slow and orderly process of erosion.Many millions of years ago, the Colorado Plateau in the Grand Canyon area contained 1,000 more feet of rock than it does today and was relatively level. The additional material consisted of some 14 layered fonnations of rock. In the Grand Canyon region these layers were largely worn away over the course of millions of years.Approximately 65 million years ago the plateaus flat surface in the Grand Canyon area bulged upward from internal pressure; geologists refer to this bulging action as upwarping; it was followed by a general elevation of the whole Colorado Plateau, a process that is still going on. As the plateau gradually rose, shallow rivers that meandered across it began to run more swiftly and cut more definite courses. One of these rivers, located east of the upwarp, was the ancestor of the Colorado. Another river system called the Hualapai, flowing west of the upwarp, extended itself eastward by cutting back into the upwarp; it eventually connected with the ancient Colorado and captured its waters. The new river then began to carve out the 277-miIe-long trench that eventually became the Grand Canyon. Geologists estimate that this initial cutting action began no earlier than 10 million years ago.Since then, the canyon forming has been cumulative. To the corrosive force of the river itself have been added other factors. Heat and cold, rain and snow, along with the varying resistance of the rocks, increase the opportunities for erosion. The canyon walls crumble; the river acquires a cutting tool, tons of debris; rainfall running off the high plateau creates feeder streams that carve side canyons. Pushing slowly backward into the plateau, the side canyons expose new rocks, and the pattern of erosion continues.1.What does the passage mainly discuss?2.In the first sentence the author refers to the Grand Canyon as a “wound” to indicate that（ ）.3.Which of the following conclusions about the Grand Canyon can be drawn from the passage?问题1选项A.Patterns of erosion in different mountain ranges.B.Forces that made the Grand Canyons.C.The increasing pollution of the Colorado River.D.The sudden appearance of the Grand Canyon.问题2选项A.it was caused by some ancient convulsionB.its presence is an embarrassment to the State of ColoradoC.it looks like an injury on the Earths surfaceD.it is caused many visitors to injure themselves问题3选项A.Its contours are constantly changing.B.It contains approximately 14 million tons of rock.C.Its eruptions have increased in recent years.D.It is being eroded by toxic waste and pollutants.【答案】第1题:B第2题:C第3题:A【解析】1.主旨大意题。文章第一段介绍了大峡谷主要是由于缓慢而有序的侵蚀作用形成；第二三段对大峡谷形成的原因和过程进行了仔细分析；最后一段进一步介绍大峡谷的进一步形成是由于各种力的作用。因此B选项“大峡谷形成的各种力”符合题意。2.推理判断题。由文章第一段中的Standing on the rim of the Grand Canyon, gazing across this giant wound in the Earths surface, a visitor might assume that the canyon had been caused by some ancient convulsion.（站在大峡谷的边缘，凝视着地球表面这个巨大的伤痕，游客可能会认为峡谷是由一些古老的震动造成的）可知C选项“看上去像是地球表面的伤痕”符合题意。3.推理判断题。由文章最后一段中的Pushing slowly backward into the plateau, the side canyons expose new rocks, and the pattern of erosion continues.（缓慢地向后推进高原，旁边的峡谷露出新的岩石，侵蚀模式继续进行）可知大峡谷的轮廓在不断变化，因此选A。2. 单选题You have to thaw the meat before it can be cooked.问题1选项A.tenderizeB.defrostC.seasonD.braise【答案】B【解析】考查动词辨析。thaw意为“(结冰后) 解冻，融化，融解”；tenderize意为“使嫩，使软化”；defrost意为“（给）化霜，（使）解冻”；season意为“加调料调味，加作料”；braise意为“炖，焖”。句意：烹饪肉之前，你得先解冻它。3. 翻译题Deepen educational cooperation in an all-round way to promote long-term development. Education is fundamental to a countrys enduring prosperity. It is necessary for us all to intensify exchanges and cooperation between educational and academic institutions, expand linkages between institutions of higher learning and carry out youth, cultural and sports exchanges in diverse forms. In particular, we should increase educational assistance to less developed countries, promote two-way flow of educational resources and raise the educational level of our region.Strengthen international cooperation in disaster reduction and relief in the spirit of helping those in need and assisting those in difficulty. As natural disasters know no national boundaries, they must be managed by cooperative efforts. In recent years, we have laid a good foundation of cooperation in responding to the sudden strike of the Indian Ocean earthquake and tsunami and other major disasters. We should step up cooperation in developing a disaster early-warning system, sharing disaster information and reduction technology
