2017年专四英语阅读基础训练题 2017年专四英语阅读基础训练题 Initiative is doing the right thing without being told.以下是小编为大家搜索整理的2017年专四英语阅读基础训练题，希望能给大家带来帮助!更多精彩内容请及时关注我们应届毕业生考试网! The case for college has been accepted without question for more than a generation. All high school graduates ought to go, says conventional wisdom and statistical evidence, because college will help them earn more money, become "better" people, and learn to be more responsible citizens than those who don' t go. But college has never been able to work its magic for everyone. And now that close to half our high school graduates are attending, those who don' t fit the pattern are becoming more numerous, and more obvious. College graduates are selling shoes and driving taxis; college students interfere with each other' s experiments and write false letters of recommendation in the intense competition for admission to graduate school. Other find no stimulation in their studies, and drop out—often encouraged by college administrators. Some observers say the fault is with the young people themselves—they are spoiled and they are expecting too much. But that is a condemnation of the students as a whole, and doesn' t explain all campus unhappiness. Others blame the state of the world, and they are partly right. We have been told that young people have to go to college because our economy can' t absorb an army of untrained eighteen-year-olds. But disappointed graduates are learning that it can no longer absorb an army of trained twenty-two-year-olds, either. Some adventuresome educators and watchers have openly begun to suggest that college may not be the best, the proper, the only place for every young person after the completion of high school. We may have been looking at all those surveys and statistics upside down, it seems, and through the rosy glow of our own remembered college experiences. Perhaps college doesn' t make people intelligent, ambitious, happy, liberal, or quick to learn things—may it is just the other way around, and intelligent, ambitious, happy, liberal, quick-learning people are merely the ones who have been attracted to college in the first place. And perhaps all those successful college graduates would have been successful whether they had gone to college or not. This is heresy to those of us who have been brought up to believe that if a little schooling is good, more has to be much better. But contrary evidence is beginning to mount up. 1.According to the author, ___.

DataFocus分析案例：2013至2017年各国制造业进出口情况

年各国制造业进出口情况

DataFocus分析案例:2013至2017年各国制造业进出口情况摘要：如何推动制造业的发展一直是制造行业想研究的问题。本文通过DataFocus数据分析系统，研究2013至2017年各国制造业进出口情况，分析不同类型国家的制造业进出口情况，找出进出口金额变化率较特殊的国家的进出口情况，了解制造业现状，提高制造业的发展。得到了以下结论：统计的78个国家的收入类型共四种，数量随等级的递增而增加；不同类型国家的进出口金额变化趋势基本相同，2013-2016年基本都处于上升趋势，而在2017年均向下走向，推测与2017年发生的“特朗普签署美国30年来最大规模税改”有关；高收入国家中，2016年前，各国进出口总额基本都处于上升趋势，而香港下降较明显；香港的进口金额缓慢上升，而出口金额不断下降，推测与香港的泡沫经济有关。关键词：制造业；进出口；香港

一、案例背景随制造业革命即将到来;未来五至十年内，所有行业的制造企业都将卷入一场争夺战，力争根据客户需求有效地进行生产。企业必须作出战略选择以维持较强的竞争力，投资科技以确保能够持续分析客户偏好和购买习惯相关数据，从而迅速应对市场变化，因此美国大通银行希望能掌握全球制造业的进出口情况，了解制造业现状，从而提高制造业的发展。二、案例问题首先基于2013至2017年各国制造业进出口情况数据，找出进出口金额最多的国家类型为高收入国家及高收入国家中变化率较特殊的国家香港。然后对香港制造业的进出口金额进行了分析。三、案例分析将分析的“2013至2017各国制造业进出口统计”、“国家名”、“时间”CSV文件导入到Focus系统中。 1.不同类型国家的数量图1不同类型国家的数量数据选取了78个国家有关制造业进出口金额的情况统计，每个国家属于不同的收入类型，首先对不同类型国家的数量进行统计。图1即为其统计图，从图1可以看到，这些国家被分为4组，分别为：低收入国家、中低等收入国家、中高等收入国家和高收入国家，比例按照收入等级的递增而增加；并发现高等收入
