朱光潜《西方美学史》考研模拟试题及详解（二）
一、名词解释
1．味
答：“味”是中国传统的一个美学范畴。它不同于“五味”的“味”，最早使用这个美学范畴的是老子。“淡乎其无味”是老子对“道”的理解，恬淡的味是最高的味。后来陶潜、王维、司空图、梅尧臣、苏轼等人都延伸发展了这种思想，从而形成了中国美学史和中国艺术史的一种审美趣味和审美风格——平淡。
2．情象
答：情象是意境系统里的一种象。情象有别于意象，心像，言象等。它分别对应原初状态里的象和再生状态的象。原初状态的情象是指作者在创作准备，是灵感来临、原初状态下发生的情思与境象相容。情是精魂，象为形质。无情，象不生；无象，情不能附着。再生状态的情象是指经过文字的创造而凝结成言象后新的情象，它不同于原初状态的情象就在于它更加凝练，是读者接受的新情象。
3．审美活动
答：审美活动是人类的一种基本的活动方式，它存在于人类丰富的现实生活中。审美活动区别于其他活动的三个特点：首先，人在审美活动中的存在不同于日常生活中的存在，它是一种超越性的存在方式。其次，人的审美中存在不同于异化活动中的存在，它是一种自由的存在方式。最后，人在审美中的存在不同于人的现实存在，它是一种应然的存在方式。从根本上说，审美活动就是人之所以为人的最具本质性的存在方式。
二、简答题
1．刘熙载：“怪石以丑为美，丑到极处，便是美到极处。一‘丑’字中丘壑未易尽言。”结合这句话谈谈中国古典美学中丑的审美意义。
答：刘熙载的“怪石以丑为美，丑到极处，便是美到极处，一‘丑’字中丘壑未易尽言”。这句话是指怪石之所以“以丑为美”，所以“陋劣之中有至好”，是在于它表现了宇宙元气运化的生命力。这一审美观，发源于庄子的命题，即美与丑可以转化、神奇可以化为臭腐。
（1）中国古典美学对丑的认识
中国古典美学体系中，“美”与“丑”并不是最高范畴，而属于较低层次的范畴。在中国美学史上，人们对于“美”和“丑”的对立，并不看得那么严重，并不看得那么绝对。人们认为，无论是自然物，也无论是艺术作品，最重要的，并不在于“美”或“丑”，而在于要有“生意”，要表现宇宙的生命力。这种“生意”，这种宇宙的生命力，就是“一气运化”。
（2）中国古典美学中丑的审美意义
①艺术家在自己作品中创造丑怪的形象
历史上出现了一些艺术家，着意在自己作品中创造丑怪的形象。唐代韩愈就常常用艰涩难读的诗句描绘灰暗、怪异、恐怖的事物，所以刘熙载说：“昌黎诗往往以丑为美。”杜甫诗中也常常描绘丑的事物和景象，并且常常使用“丑”、“老丑”一类的字眼。书法家中追求丑怪的人就更多。清初的傅山甚至直接喊出“宁丑毋媚”的口号。在这些艺术家看来，艺术中的“丑”不仅不低于“美”，而且比“美”更能表现生命的力量，更能表现人生的艰难，更能表现自己胸中的勃然不可磨灭之气。
②以美为主，以丑衬美的审美意识，在中国古典美学中具有重要地位
丑的特征因美的对照而更加显著，反之亦然。唐代刘禹锡“沉舟侧畔千帆过，病树前头
万木春”以死寂病态的丑来衬托充满生机活力的社会和自然的壮美，这种以丑衬美的认识早于西方近千年。丑的表现往往在使人们在感官上对世界的认识更鲜明、更深刻。
③化丑为美，即把现实丑转化为艺术美，是中国美丑观的又一重要观念
其效果是通过对丑恶现象的艺术加工引起审美快感。因为艺术所展示的不是现实中原封不动的丑，而是被赋予了艺术形象的对象，它的内容会引起人们道德伦理的批判，而形式却给人以艺术享受，唤起审美快感。甚至很多人认为丑的形象比美的形象更具感染力和冲击力。这里的化丑为美又分两种，即由人物外表丑化为对象心灵美的，和化人物丑为作家美的。丑显示着生命力的旺盛，勃发着一种恶狠的，自虐性的快感。
2．席勒：“只有当人充分是人的时候，他才游戏；只有当人游戏的时候，他才完伞是人”谈谈你对这句话的理解。
答：（1）对这句话的理解
席勒“只有当人充分是人的时候，他才游戏；只有当人游戏的时候，他才完伞是人”这句话是说人之所以会产生游戏的冲动，是因为生命力的盈余。即当人充分是人的时候。游戏可以调和人身上自然与理性的矛盾，使人处于自由状态，从而达到人性的完满实现。即人完全是人。席勒阐发了他关于游戏说的两个观点：
①“过剩精力”是文艺与游戏产生的共同生理基础
席勒在康德的基础上加以发挥，他认为人的艺术活动是一种以审美外观为对象的游戏冲动。“过剩精力”是文艺与游戏产生的共同生理基础。所谓游戏，其实也就是一种审美活动。在席勒看来，人之所以会产生游戏的冲动，是因为生命力的盈余。审美的游戏，是对动物性游戏的提升，它根本上是一种想象力的游戏。游戏作为游戏冲动作为调和感性冲动和理性冲动的中介，创造了最广义的美。
②自由是审美与游戏的根本特征
游戏可以调和人身上自然与理性的矛盾，使人处于自由状态，从而达到人性的完满实现。席勒认为，游戏的根本特征在于自由。而人只有在审美活动中才是自由的。基于以上观点，他认为审美与游戏是相通的。这也正是在审美摆脱任何外在目的，而以自身为目的，心灵各种内力达到和谐因而是自由的这意义上使用游戏这一概念的原因。
席勒认为，游戏不仅是审美活动的根本特征，而且是人摆脱动物状态达到人性的一种主要标志。席勒所说的游戏，是指人在摆脱了物质欲望和道德必然性的懒散后所从事的一种真正自由的活动。游戏，其实就是一种审美活动。（
（2）席勒“游戏说”的贡献与不足
他试图从人的生命活动的独特性质中去探寻审美发生的直接精神动力，并且敏锐地揭示审美活动与人自由本质之间的内在关系。他既看到了人的审美活动与动物游戏活动的不同，也发现二者之间存在的某种深层的联系。
然而席勒“游戏说”忽视了对动物相认的游戏转化过程的机制及人的游戏得以发生和进行的社会历史条件的探讨。在席勒看来，游戏与审美几乎是同义词。
3．鲍姆嘉通认为美学是感性学，黑格尔认为美学是艺术哲学，比较两者的区别与联系。
答：鲍姆嘉通是德国启蒙运动时期的哲学家、美学家。历来在美学史上形成共识的看法是他第一个采用Aesthetica的术语，提出并建立了美学这一特殊的哲学学科，被誉为“美学之父”。而黑格尔是德国古典美学的集大成者。他们对于美学都有各自不同的看法。
鲍姆嘉通与黑格尔两者的区别和联系如下：
（1）区别
①两者的美学研究对象不同
鲍姆嘉通认为美学对象就是研究美，美感和艺术美的规律，就是研究感性认识的完善。美学所研究的规律可以应用到一切艺术，“对于各种艺术有如北斗星”。而黑格尔认为美学对象是研究美的艺术。他把自然美排除在美学研究领域之外，他之所以研究自然美，是因为自然美是心灵美的反映形态。可见，黑格尔认为美学的研究对象只是艺术美。
②两者的美学定义的侧重点不同
鲍姆嘉通重感性。他不满意以往的理性主义哲学对感性认识的的贬低和轻视，注重感性认识，主要是审美意识和艺术问题的严肃的哲学沉思。因此，他提出了美学对象就是感性认识的完善。由此可见美学虽是作为一种认识论提出的，同时也是研究艺术和美的科学。
黑格尔重理念。他在《美学》开始就宣布他“所讨论的并非一般的美，而是艺术的美”，并且认为美学的正当名称应该是“艺术哲学”。这样，他就把美学的范围界定下来，排除了“自然美”。黑格尔的全部美学思想都是从一个中心思想生发出来的，这就是他对美的定义：“真，就它是真来说，也存在着。当真在它的这种外在存在中是直接呈现于意识，而且它的概念是直接和它的外在现象处于统一体时，理念就不仅是真的，而且是美的了”。美因此可以下这样的定义：美就是理念的感性显现。理念就是绝对精神，也就是最高的真实，黑格尔又把它叫做“神”、“普遍的力量”、“意蕴”等。这就是艺术的内容。
（2）联系
鲍姆嘉通鼓励感性认识以及在目的论上，对后来西方美学思想的影响是巨大的。黑格尔的美学思想也明显受到他的影响，提出了美是理念的感性显现。黑格尔所处时代的形式主义和感性主义在当时美学界以至在现在的资产阶级美学界都是占优势的。黑格尔的全部美学思想就是要驳斥这种风靡一时的形式主义和感性主义，强调艺术与人生重大问题的密切联系和理性的内容对于艺术的重要性。同时他们都强调美学是对艺术的研究，都不排斥艺术中的感性和理性因素。

Choose the best word（s）for each numbered blank and mark A, B, C, or D on ANSWER SHEET 1.（10 points） Among the thousands of business schools now operating around the world you would be hard-pressed to find one that doesn't believe it can teach the skills of entrepreneurship. However, of the people who immediately 1 to mind when one thinks of entrepreneurs——Bill Gates, Richard Branson or Oprah Winfrey, for example—few have done more than 2 a speech at a business school. 3 , a recent study by King's College in London has suggested what many intuitively 4 : that entrepreneurship may actually be in the blood—more to do with genes than classroom experience. All of which 5 the question—does an entrepreneur really need a business-school education? Not surprisingly some of the best-known schools in the field have a 6 answer to this: they don't actually profess to create entrepreneurs, 7 they nurture innate ability. Or as Timothy Faley of the entrepreneurial institute at Michigan's Ross School of Business 8 it: “A good idea is not enough. You need to know how to 9 a good idea into a good business.” Schools do this in a number of ways. One is to 10 that faculty are a mix of classic academics and businesspeople with experience of 11 their own successful firms. They can also create “incubators” where students 12 ideas and rub shoulders on a day-to-day basis with the external business world, receiving both advice and hard cash in the form of investment. Arguably such help is now more important than ever. The modern entrepreneur is faced with a more 13 world than when Richard Branson began by selling records out of a phone box. According to Patrice Houdayer, head of one of Europe's best-known entrepreneurship schools, EMIYON in France, new businesses used to move through a 14 series of growth steps—what he terms garage, local, national and international. Now however, 15 the communications revolution, they can leapfrog these stages and go global more or less straightaway—encountering a whole new 16 of problems and challenges. In this 17 Professor Houdayer maintains that the increasingly 18 nature of MBA classes can help the nascent entrepreneur in three ways: by plugging them into an international network of contacts and advisors, by preparing them for the pitfalls and opportunities 19 with dealing across different cultures and by 20 them to the different ways that business is conducted around the globe.

(10 points) Facebook has been 1 with fire and has got its fingers burned, again. On November 29th America’s Federal Trade Commission (FTC) announced that it had reached a 2 settlement with the giant social network over 3 that it had misled people about its use of their personal data. The details of the settlement make clear that Facebook, which 4 over 800m users, betrayed its users’ trust. It is also notable because it appears to be part of a broader 5 by the FTC to craft a new privacy framework to deal with the rapid 6 of social networks in America. The regulator’s findin gs come at a 7 moment for Facebook, which is said to be preparing for an initial public offering next year that could value it at around $100 billion. To 8 the way for its listing, the firm first needs to resolve its privacy 9 with regulators in America and Europe. 10 its willingness to negotiate the settlement 11 this week. Announcing the agreement, the FTC said it had found a number of cases where Facebook had made claims that were “unfair and deceptive, and 12 federal law”. For instance, it 13 personally identifiable information to advertisers, and it failed to keep a promise to make photos and videos on deleted accounts 14 . The settlement does not 15 an admission by Facebook that it has broken the law, but it deeply 16 the company nonetheless. In a blog post published the same day, Mark Zuckerberg, Facebook’s boss, tried to17 the impact of the deal. First he claimed that “a small number of high-profile mistakes” were 18 the social network’s “good history” on privac y. The FTC is not relying on Facebook to police itself. Among other things, the company will now have to seek consumers’ approval before it changes the way it shares their data. And it has agreed to an independent privacy audit every two years for the next 20 years. There is a clear pattern here. In separate cases over the past couple of years the FTC has insisted that Twitter and Google accept regular 19 audits, too, after each firm was accused of violating its customers’ privacy. The intent seems to be to create a regulatory regime that is tighter than the status quo, 20 one that still gives social networks plenty of room to innovate. 1.

(1) (But this may have less to do with the luring call of academic surroundings than with changing market conditions —a factor that academic critics rarely take into account.) Robert Silverberg, a former president of The Science Fiction Writers of America, is one of the most prolific professionals in a field dominated by people who actually write for a living. (Unlike mystery or Western writers, most science-fiction writers cannot expect to cash in on fat movie sales or TV tie-ins.) (2) (Still in his late thirties, Silverberg has published more than a hundred books, and he is disarmingly frank about the relationship between the quality of genuine prose and the quality of available outlet. )By his own account, he was “an annoyingly verbal young man ” from Brooklyn who picked up his first science-fiction book at the age of ten, started writing seriously at the age of thirteen, and at seventeen nearly gave up in despair over his inability to break into the pulp magazines. (3)( At his parents ’ urging, he enrolled in Columbia University, so that, if worst came to worst, he could always go to the School of Journalism and “get a nice steady job somewhere ”.) During his sophomore year, he sold his first science-fiction story to a Scottish magazine named Nebula. By the end of his junior year, he had sold a novel and twenty more stories. (4) (By the end of his senior year, he was earning two hundred dollars a week writing science fiction, and his parents were reconciled to his pursuit of the literary life. )“I became very cynical very quickly,” he says. First I couldn ’t sell anything, then I could sell everything. The market played to my worst characteristics. An editor of a schlock magazine would call up to tell me he had a ten-thousand-word hole to fill in his next issue. I ’d fill it overnight for a hundred and fifty dollars. I found that rewriting made no difference. (5)( I knew I could not possibly write the kinds of things I admired as a reader —Joyce, Kafka, Mann —so I detached myself from my work.) I was a phenomenon among my friends in college, a published, selling author. But they always asked, “When are you going to do something serious?” —meaning something that wasn ’t science fiction —and I kept telling them, “ When I ’m financially secure.” 答案 1.但是这一点与其说是与学术环境具有诱惑力的召唤有关，还不如说是与变化的市场状况有关——一这是一个学术评论家很少考虑的因素。 2.还不到四十岁，西尔弗伯格就已出版了一百多本书籍，而他对真正散文的质量与应时之作的质量之间的关系十分坦诚，毫无掩饰。 3.在他双亲的敦促下，他报考了哥伦比亚大学，所以即便最糟他也能进入新闻学校，“将来总可以有一份稳定的好工作。” 4.到大四结束的时候，他每星期写科幻小说已经可以赚两百美元了，而他的双亲也接受了他对于文学生涯的追求。 5.我知道我写不出作为读者的我所喜欢的东西，就像乔伊斯、卡夫卡、曼恩的作品，所以我不再那么关注我所写的东西。 总体分析 本文介绍了科幻小说家罗伯特·西尔弗伯格。文章先指出科幻小说的繁荣与市场需求关系紧密，接着通过介绍多产的科幻小说家西尔弗伯格的创作经历予以说明。 本文考查的知识点：后置定语、插入语、比较结构、同位语、上下文中词义的选择，等。

(10 points) Could a hug a day keep the doctor away? The answer may be a resounding "yes!" 1 helping you feel close and 2 to people you care about, it turns out that hugs can bring a 3 of health benefits to your body and mind. Believe it or not, a warm embrace might even help you 4 getting sick this winter. In a recent study 5 over 400 health adults, researchers from Carnegie Mellon University in Pennsylvania examined the effects of perceived social support and the receipt of hugs 6 the participants' susceptibility to developing the common cold after being 7 to the virus .People who perceived greater social support were less likely to come 8 with a cold ,and the researchers 9 that the stress-reducing effects of hugging 10 about 32 percent of that beneficial effect. 11 among those who got a cold, the ones who felt greater social support and received more frequent hugs had less severe 12 . "Hugging protects people who are under stress from the 13 risk for colds that's usually 14 with stress," notes Sheldon Cohen, a professor of psychology at Carnegie. Hugging "is a marker of intimacy and helps 15 the feeling that others are there to help 16 difficulty." Some experts 17 the stress-reducing , health-related benefits of hugging to the release of oxytocin, often called "the bonding hormone" 18 it promotes attachment in relationships, including that between mother and their newborn babies. Oxytocin is made primarily in the central lower part of the brain , and some of it is released into the bloodstream. But some of it 19 in the brain, where it 20 mood, behavior and physiology. 1．[A] Unlike [B] Besides [C] Despite [D] Throughout 2．[A] connected [B] restricted [C] equal [D] inferior 3．[A] choice [B] view [C] lesson [D] host 4．[A] recall [B] forget [C] avoid [D] keep 5．[A] collecting [B] involving [C] guiding [D] affecting 6．[A] of [B] in [C] at [D] on 7．[A] devoted [B] exposed [C] lost [D] attracted 8．[A] across [B] along [C] down [D] out 9．[A] calculated [B] denied [C] doubted [D] imagined
