2022年考博英语-东华大学考前模拟强化练习题（附答案详解）1. 单选题Although Asian countries are generally more _ in social customs than Western countries, there have been several notable examples of women leaders in both China and India.问题1选项A.conservativeB.confidentialC.comprehensiveD.consistent【答案】A【解析】考查形容词辨析。A项conservative“守旧的、传统的、拘谨的”；B项confidential“机密的、秘密的”；C项comprehensive“广泛的”；D项consistent“一致的、调和的”；句意：与西方国家相比，尽管亚洲国家在社会习俗上普遍较为保守，但在印度和中国却出现过几位著名的妇女领导人。因此该题A项正确。2. 单选题For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the U.S. had acquired when it purchased Louisiana, and the Apollo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war.Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science by going where no scientists had gone before. Today Mars looms as humanitys next great terra incognita. And with doubtful prospects for a short-term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planets reddish surface. Could it be that science, which has long played a minor role in exploration, is at last destined to take a leading role? The question naturally invites a couple of others: Are there experiments that only human could do on Mars? Could those experiments provide insights profound enough to justify the expense of sending people across interplanetary space?With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions the bacterial fossils rode to Earth on a meteorite (陨石) from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe.1. According to the passage, the chief purpose of explores in going to unknown place in the past was_.2. At present, a probable inducement for countries to initiate large-scale space ventures is_.3. What is the main goal of sending human missions to Mars?4. By saying “With Mars the scientific stakes are arguably higher than they have ever been”, the author means that_.5. The passage tells us that proof of life on Mars would _.问题1选项A.to display their countrys military mightB.to accomplish some significant scienceC.to find new areas for colonizationD.to pursue commercial and state interests问题2选项A.international cooperationB.nationalistic reasonsC.scientific researchD.long-term profits问题3选项A.tTo find out if life ever existed there.B.tTo see if humans could survive there.C.tTo prove the feasibility of large-scale space ventures.D.tTo show the leading role of science in space exploration.问题4选项A.with Mars the risks involved are much greater than any previous space ventures.B.in the case of Mars, the rewards of scientific exploration can be very highC.in the case of Mars, much more research funds are needed than ever beforeD.with Mars, scientists argue, the fundamental interests of science are at issue问题5选项A.make clear the complex chemistry in the development of lifeB.confirm the suggestion that bacterial fossils traveled to Earth on a meteoriteC.reveal the kind of conditions under which life originatesD.provide an explanation why life is common in the universe【答案】第1题:D第2题:C第3题:D第4题:B第5题:C【解析】1.【试题解析】：事实细节题。根据explorers go to unknown定位到全文首句。首句中提到，几个世纪以来，出于或多或少的经济原因及国家主义原因，探险家冒着生命危险深入到未知领域。本题是询问主要目的，所以reasons的定语从句中的内容即为答案“for reasons that were to varying degrees economic and nationalistic”，由此可知答案为D。2.【试题解析】: 判断推理题。题目的意思是说促使各个国家大规模的太空探险的主要诱因是什么，定位到第2段，“it is clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planets reddish surface.”可得知去太空探险是为了留下人类的痕迹也就是为了科学的探索，因此，答案为C。3.【试题解析】:判断推理题。根据main goal这一个关键词定位到第23段第43句。定位到原文，可得知在以往探险中一直扮演次要角色的科学这一次终于注定是主角了吗？?说明在以往探险中
