  • 第5题:


    Paragraph 5 supports which of the following inferences about the commercial revolution between AD 1000 and 1300?( )

    A.It had very little impact on social attitudes and values.
    B.It brought about major political changes throughout Europe.
    C.It lessened the influence of the church.
    D.It increased the population of small towns.

    答案:A
    解析:
    推断题。根据题干关键词commercial revolution定位到文章第五段第一、二句。题干要求根据第五段内容选出关于商业革命的合理推断,需要根据上下文做出合理的逻辑分析。第五段阐述了商业革命带来的社会影响。B项“给整个欧洲带来了重大的政治变革”,原文并没有说明商业革命是否导致政治变革,故B项错误。第五段倒数第二句指出贵族阶层和教士决定主导的社会态度、价值观、思想和行为模式。因此C项“减轻了教会的影响”与原文不符。D项“增加了小城镇的人口”与原文Most towns remained small不符。A项“对社会态度和价值观的影响很小”,根据第五段最后两句可知,十一世纪的商业革命改变的是城市文化生活,对社会态度和价值观的影响甚微,A项表述正确。故本题选A。参考译文:从十二世纪六十年代开始,欧洲北部新银矿的开发促使了大量银币的铸造和流通。现金的广泛使用极大地增加了国际贸易量。贸易的业务流程发生了根本性的变化。以前,游商一个人几乎要负责贸易业务的各个方面,后来就演变成了三种不同角色的商人各司其职的运作模式:店商负责“总部”的运转,出资并组织管理公司整体进出口贸易业务;专职的货运人员负责通过陆路和海路运输货物;居住在国外城市的公司代理商,根据总部的建议,负责销售和采购。以前,一个商人就能监管贸易过程的所有事项,并且买卖双方能直接商定价格进行交易,商业信函并没有什么作用。但分工明确后,商业信函开始大量出现。之后,商业城市之间常规的快递服务开始兴起。当企业不得不开始与股东、制造商、客户、分支机构、员工和竞争对手打交道时,商业会计就变得更加复杂。道路通行费变高,高到足以为所谓的道路改革提供资金,道路改革包括建造新的路面和桥梁、穿过阿尔卑斯山的新隧道,以及为旅客提供的新旅馆和招待所。商家间的相互信任促进了赊销(先收货后付款)的增长,从而促进了金融领域的新发展:比如汇票的产生,使耗时长且有风险的长途硬币运输变得不再必需。德国汉萨同盟的商业探索活动很好地体现了这些进步。汉萨同盟是欧洲城镇的商业协会,可追溯到1159年。到十四世纪末,该同盟迅速扩大到包括荷兰和波兰在内的约200个城市。沿着波罗的海和北海的常规、明确的贸易路线,同盟城市的船只运输大量的毛皮、蜡、铜、鱼、谷物、木材和酒。这些货物主要用于交换西部城市的其他成品,主要是布料和盐。在布鲁日和伦敦等城市,汉萨商人获得了特殊的贸易优惠,免除了所有通行费,并允许他们在当地的集市售卖商品。汉萨商人建立了国外贸易中心,其中最著名的是“伦敦钢院”,一个有仓库、办公室、教堂、公司代表住处的封闭社区。到了十三世纪末,汉萨商人开发了一种重要的商业技术,即商业登记。商人们公开记录他们的债务和合同,并且会得到同盟的担保。这种方式在北欧地区的信贷和商业发展中起到了决定性的作用。这些发展进步被一位现代学者称为“商业革命”。从长远来看,中世纪的商业革命(公元1000年~1300年)给欧洲社会带来了根本性的变化。其中一个显著的变化是,商人只占人口的一小部分,不到10%。但是他们带来的影响却远远超过了10%这个数字。商业革命创造了大量的新财富,这意味着人们会有更高的生活水平。财富的存在并没有逃过国王和其他统治者的眼睛。财富需要纳税,通过征税,国王可以创造出强大的中央集权国家。在之后的几年内,与中产阶级的联盟关系使国王能够削弱贵族的利益,并建立了“现代”国家。商业革命还为成千上万的农业工人提供了提高社会地位的机会。欧洲社会从几乎完全孤立的农村向相对更加城镇化的情况开始缓慢但稳定地转变,这是十一世纪的商业革命带来的最大影响。尽管如此,除意大利中部和北部地区以及弗兰德斯郡以外,商人们并没有掌控中世纪的社会。大多数城镇规模依然很小。贵族阶层和教会人士决定了主导的社会态度、价值观、思想及行为模式。然而,十一至十四世纪的商业变革确实为城市生活和文化的发展奠定了经济基础。

    C

    They have made innovative tools more and more irrelevant.

    正确答案: A
    解析:
    录音中指出了新的信息和通讯技术正在驱动着世界经济(New information and communication technologies are driving the global economy),也即是为世界经济提供力量,所以B项正确;他们降低了全球通讯成本(They have brought down the cost of global communication),所以A正确;创新方式更易使用(innovative tools have become easier to use),所以C项的表述“他们使得创新方式越来越不重要”不正确;互联网,手机和电子资金转账系统正在打开全球市场(The Internet, mobile phones and electronic funds transfer are opening up the global marketplace),所以D项也正确。

    C.Democracy Has Lost Its Appeal Nowadays
    D.Images in the Information Age

    答案:A
    解析:
    主旨题。文章意在展示信息时代影像的影响力,说明人们总是容易相信眼睛看到的东西。故本题选A。参考译文:如果我们能弄清楚朝鲜在网上发布的那些令人费解的视频有何含义,也许我们在应对朝鲜的核挑衅行为时能更自如些。朝鲜最近发布的一段视频中出现了如下内容:一名正在做梦的男子、一些朝鲜文字、起火的摩天大楼,以及正飞越太空的火箭。视频的背景音乐是钢琴家弹奏的《天下一家》,节奏处理得很哀婉。这是一种无害的幻想,还是一种正式的挑战?针对这一视频西方是否应该发表声明回应?西方是不是也应该发布一段自己的视频?这些问题很难回答。传统媒体正在被互联网“取代”。然而,信息经济释放的“信息”往往难以解读,炮制这些“信息”的目的也难以辨明。电影研究学者斯蒂芬·阿普康在本周出版的《影像时代》一书中称,如今可以探讨一种建立在解读此类非语言信息基础上的新型“读写能力”。阿普康这本书往低了说是关于电影“语言”的,但该书还蕴含着更深的哲学思想。如今,我们的文化日益全球化。尽管文化依然依赖于文字,但文字已越来越多地被包含在影像中,最终留在人们记忆中的也是影像。南加州大学电影艺术学院院长伊丽莎白·戴利认为,写作在今天的地位与文艺复兴前夕的拉丁语类似,是一种学术界使用的语言。YouTube网站上的视频以及其他影像材料则相当于当时的意大利语。它们都是人们日常使用的语言,也是许多创新思维的媒介。一直以来,形象在公共辩论中所起的作用比我们承认的要大。几乎没人在乎理查德·尼克松在1960年与约翰·肯尼迪的总统辩论中整体发言质量略胜一筹,他们只看到这位共和党人胡子拉碴、仪容不整。阿普康援引一位神经科学家的话说,人们如此习惯于捕捉一些微妙的信号,以至于他们往往在看到政治人物的第一眼就“立刻”决定自己是否喜欢这个人。而如今,那些情感冲击力巨大、直观的非语言信息能够得到更广泛的传播。比如,2009年6月,在伊朗总统选举不合法引发抗议期间,一个名叫娜达·萨勒什·阿哈·索尔丹的女孩被枪杀的视频传遍了全世界。而在那部令观众动容的纪录片《科尼2012》(该视频在6天内被浏览了1亿次)中,一些美国政治积极分子呼吁军方逮捕一个乌干达军阀。阿普康指出,视觉是人类最信任的感官,因此需要谨慎对待。当前存在一种挥之不去的危险,就是那些虐待过程的影像可能令公众极度不安,促使他们要求政府出兵。这可以说正是1992年索马里大饥荒时的情况,当时美国在仓促间决定对索马里进行军事干预。阿普康表示,将来我们可能需要“同时具备怀疑精神和敏锐的判断力”,让民众能够“比较辩证地评论呈现在自己面前的内容”。但这一点很难实现。当影像激发出来的情感与语言的论证逻辑得出同一结论时,人们通常能够轻易做出决定。然而当两者的结论相互抵触时,人们必然会偏向其中一方。直到最近,国家治理、学生研究和司法判决的核心才将我们的强烈感情从谨慎思维中净化出来。然而,如今的影像极度丰富和富有冲击力,已经主导了我们的思维过程。尽管阿普康喜欢YouTube的即时性,但他担心,政治宣传人员很快就将学会编造故事来满足“隐藏的心理需求”,从而轻易操控选民。民众对投票的看法有两种。第一种是基于身份来投票。你是农民,那么你就投票给最偏向农民的候选人。第二种则是基于观点来投票,而不是考虑自己的身份。你认为销售税应该取代所得税,那么你就投票给持相同观点的候选人。然而,现在这种基于影像的沟通过程,与身份或观点几乎没什么关系。这种过程只与“最低公分母原则”有关,在这种原则下,你只是一种叫做人类的动物而已。对这个问题没什么显而易见的解决办法。就算我们拥有阿普康所说的怀疑精神,某种特定机制在感知、吸收和解释信息时会“带有”特定风格。你可能不会觉得印刷机与“新教”有任何关联。然而印刷机似乎是新教兴起的先决条件。与此类似,我们的民主制度尽管不太完美,却代表了文字文化发展的顶峰。阿普康告诉我们,在1960年的几次总统辩论中,肯尼迪“利用了一种能够操纵心理的东西,比起单纯的事实,这种东西具有更为原始的力量”。回想起来,那是个不祥的时刻。一旦你发现了这种东西,民主制度岂不是注定会丧失一些吸引力?就像一部你已预知结局的侦探小说一样。

  • 第19题:

    问答题
    Practice 3  You should spend about 40 minutes on this task.  Write about the following topic:  Happiness is considered very important in life. Why is it difficult to define? What factors are important in achieving happiness?  You should write at least 250 words.

    正确答案: 【参考范文】
    Throughout the history of human being, people are always pursuing happiness while nobody can give a definition nor can a consensus be achieved. Generally, happiness consists of two levels: material level and spiritual level. As far as I am concerned, spiritual happiness can bring people with greater satisfaction.
    To begin with, being happy is not a mood under certain circumstances, but a person with a certain set of attitudes. It is difficult for anyone to get what he wants without a great deal of effort. After making great and arduous effort, even if the target is achieved as expectation, there is nothing left but suffering and pain, because he amplifies the efforts rather than emphasizes the harvests. To reach the happiness they seek, however, the only thing people should do is to change their attitude toward happiness, and the way they look at the world around them.
    Moreover, happiness is not what people are born with but what people take action to get. Many people seek their unique happiness through imagination and daydreams. Obviously, everyone fantasies sometimes. But, without actions, no one can come close to finding the happiness he seeks. Happiness and bliss cannot be found merely through unrealistic envision, but must be sought through actions, through doing.
    To sum up, although we say that happiness is rooted in optimistic attitudes, it can never be achieved without any effort. It arises spontaneously from within as small goals are reached.

    单选题
    Which of the following is NOT true about elephants?
    A

    Usually elephants die at age of 60-70.

    B

    The female Asian elephants do not carry tusks.

    C

    Most mature elephants with good ivory are killed illegally.

    D

    Elephants are killed for ivory and meat.


    正确答案: D
    解析:
    录音中提到“Although elephants can live for up to 60-70 years, with the threat from ivory poaching few mature elephants with good ivory reach this age.”(尽管大象可以生活长达60-70年,但是由于象牙偷猎活动的威胁有良好象牙的成年大象很少达到这一年龄),所以C项正确,但是由此不能推断出通常大象都在60-70岁时死去,故A项错误。根据录音可知,雄性和雌性非洲象都有象牙,但是只有雄性的亚洲象有象牙,由此可知,雌性亚洲象没有象牙,所以B项正确。根据“Elephants are also being killed for their meat”可知,D项也正确。
