（l6 分）①人类之所以有今天这样的文明，文学在其中的力量和功德是不言而喻的。

难道文学要中断这样的责任了吗？让生活向下还是向上，向善还是向恶，难道文学就完全没有必要对这样最起码的问题进行拷问吗？“如果川端康成与大江健三两人生活的年代颠倒一下，大江在川端时代写大江式的作品，川端在大江的时代写川端式的作品，这两个日本人还会获得诺贝尔文学奖吗？”回答几乎是肯定的：不会。

因为川端时代的文学的标准还不只是“深刻”一维。

而大江时代，却将川端文学的命根子——美——彻底抛弃了。

②这个时代，是一个横着心要将“美”搞成矫情字眼、一提及就自觉浅薄的时代。

这个时代是讲思想神话的时代，悠悠万事，唯有思想——思想宝贝。

文学企图使人相信，在这个世界上，唯一值得人们尊重的就是思想，思想是高于一切的；谁在思想的峰巅，谁就是英雄，谁就应当名利双收。

正是在这样的语境中，我们患上了“恋思癖”的毛病。

对思想的变态追求，已使我们脱离了常识。

当我们穷凶极恶地在追求思想深度的时候，我们忘记一个掌识：获得石油必须钻井，因为石油蕴藏在具有一定深度的地下，但如果以为钻得越深就越有石油那就错了，因为再无止境地钻下去，就是泥浆和岩浆了。

思想崇拜，会导致思想迷信，而思想迷信则一定会导致思想的变态，其结果就是我们放弃常识，进入云山雾罩的思想幻觉。

其实，一旦背离真实，一个看上去再深刻的思想，也是无意义的。

（）这世界上有力量的并不只有思想。

我还是愿意重复我的老话：美的力量丝毫也不亚于思想的力量，有时甚至比思想的力量更加强大。

③“一种牺牲民族甚至人类体面的文学境界，是值得我们赞美和崇尚的境界吗？”斯洛文尼亚的齐泽克在谈到前南斯拉夫时代萨拉热窝被围困的情状时说，那些闻风而来的西方记者争先恐后寻找的只是：残缺不全的儿童尸体、被强奸的妇女、饥饿不堪的战俘。

这些都是可以满足饥饿的西方眼睛的绝好食粮。

（9分）当代阅读宣言①一个正在被技术改写的时代，需要我们对当代阅读作出以下思考：②在资讯全球化、传播形态和传播方式日新月异的浪潮下，以开放的态度开启阅读方式的革命，以主动的姿态应对传播技术的变革，是馆藏阅读书籍者和关注公共阅读潮流人理所当然的责任。

③20世纪70年代，法国哲学家利奥塔在《后现代状况》中这般描述：学术知识将转换成电脑语言，教师的角色将被电脑存储库取代，学生可以坐在终端机前随时调用——（a）人们尚存疑惑：书籍，作为人类千年文明传承的载体，难道终有一天将成为被人遗弃的标本？④科技的发展，可以让预言变成现实。

在搜索引擎强大的聚合功能面前，古典图书馆正显露颓势；在网络传播即时海量的模式面前，耕作式深度阅读变得不合时宜；在一切皆可数字化的年代，翻阅纸张正沦为向牧歌时代致敬的行为艺术……拿起终端、放下纸张；追求愉悦、告别沉思；亲近感性、疏离理性——（b）仿佛正如英特尔总裁安迪·格鲁夫所言，技术具有创造和毁灭的力量。

人们担心，新的传播形态，让即时阅读成为可能，但也不可避免地会导致“浅薄时代”的到来。

⑤时代在变，读者正在被改变。

在Internet面前，我们需要告别的，只是书籍崇拜，而非文明和文字。

我们坚信，离开了纸张，人类依然可以触摸文明的灵魂。

从竹简、羊皮纸、纸张到电子书，介质永远在变，但阅读作为人类最高精神体验方式的地位，却从未被根本撼动。

面对数字文明的冲击，人类的困惑和犹疑，也许不过是伊索寓言里的那只布里丹的驴子——（c）同时面对着两堆稻草左顾右盼，不知所措。

面对技术浪潮的汹涌澎湃，人类不应拒绝或冷眼旁观，而要接纳并迎头赶上。

Many of my peers also __41__ for the job, including some very competitive and intelligent students from famous universities.But why did the interviewer pick me instead of them?Finally, __42 __ pushed me to ask the interviewers after we became colleagues.

My job was to help foreign visitors experience the beach. I thought it would be very easy because my oral English was __47__ good. But when I went to talk with a group of foreign guests, I suddenly realized that I did not know a single beach volleyball term. I was embarrassed.After this, I read brochures in both Chinese and English every day to learn the terms for facilities and related words. This allowed me to deliver accurate __48__ to foreigners, and I was happy to work responsibly.After theseexperience, I’m more confident and I strongly believe that my fate is in my __49__.

Choose the one that fits best according to the information given in the passage you have just read.AIf you asked me, over a year ago, to choose between the neon lights and street lights of Chengdu, I would have chosen the colourful ones without hesitation. But my experiences during the time of the severe earthquake have given me a different perspective.In fear of the after shocks people would be constantly moving about and they stayed out of doors during the nights. When night fell and rain set in, we could feel cold, tired and helpless. But I remember one night, which changed my whole attitude to the lights of Chengdu. All of a sudden, there was a beam of yellow, then another, and another. Before we knew it, there were lights oneverywhere. The sea of light had the effect of making us feel overwhelmingly secure.I realized that the lights, which we had taken for granted before, were protecting the whole city.Then there were the people who came to our rescue, who made every effort to protect and save lives. I saw local taxi drivers on the road all night long transporting injured people to the hospitals. I saw volunteers from other parts of China hurrying with living essentials to the worst-hit areas…At that moment, Chengdu became a place where the word ‘love’ was being spelt in capital letters by caring people from every corner of the planet.Reconstruction is still in progress, but I’ve already come to understand that the quality of life in Chengdu comes not from the number of its modern buildings… but from the hope, the faith, the optimism, and the determination of the people…65.What does the underlined word mean?A. determinationB. evaluationC. destinationD. viewpoint66.What did the writer think of the street lights before the earthquake?A.The writer thought the street lights were very important to the people.B.The writer believed people couldn’t do without street lights.C.The writer considered the street lights as something natural.D.The writer had no idea about the street lights.67.What’s the best title for this passage?A. EarthquakeB. Lights in RainC. Hope, the LightsD. Love of PeopleBIn the UK, students’residence halls are run as profit-making business, but this can occasionally be to students’ disadvantage.As many universities choose to contract out their hall’s management to private companies, room rents are rising and student rights are suffering.In 20XX, 55 percent of student rooms were managed by private companies --- only 27 percent by universities and colleges, the National Union of Students (NUS) has reported.These private companies are improving the hall’s facilities in return for higher room rents. The most noticeable example of this trend is the growth in luxury halls. These are halls for students willing to pay more for larger rooms with better services.Chancellors Court, at EdinburghUniversity in Scotland, is one such luxury hall. Rooms are divided between standard and large, with larger rooms costing 173 pounds each week, 40 pounds more than smaller rooms. They come with a scenic view, color TV, fast Internet connection and a modern bathroom.Other luxury halls have private gyms for their residents. Private companies capitalize (用…以牟利) on their investment by renting out the students rooms to travelers over the summervacation period.But the NUS is concerned that luxury halls are affecting room rents at standard un-privatized halls. Most students in the UK pay on average 126 pounds a week for a private room in catered (提供餐饮的) halls of residence, the International Students Advice and Welfare organization has reported. According to the NUS, rent in UK halls of residence has risen by almost a quarter from 20XX to 2021.Veronica King, NUS vice-president of welfare, wants the privatization of university accommodation to stop.“For the students for whom luxury is not affordable, there is a significant risk that accommodation costs, coupled with the burden of complete fees, may reduce the choice of where to go to university,” she said.Legal quarrels with privatized (私有化了的) halls may also account for some of the 10 percent per year rise in student complaints to the office of the Independent Adjudicator for Higher Education (OIA). The OIA is an independent student complaints scheme that has authority over all higher education institutions in England and Wales.Rob Behrens, chief executive of the OIA, said he was unsurprised by the rise in complaints. “The bottom line is that students are today more self-confident in thinking about what their rights are and what are the things they can get form the commitments they make.”68.Why are room rents rising in British universities?A.Because the world is facing a financial crisis.B.Because most universities are getting bored about students’ complaints.C.Because many universities let private companies run students’ halls.D.Because not all universities can meet the demands of the students.69.Which of the following is not mentioned about a luxury hall?A.Students have to pay more for a luxury hall.B.Students can have a good view in a luxury hall.C.Students can enjoy their own gym in a luxury hall.D.Students can have an Internet connection free of charge.70.Why do some students want to pay more for a luxury hall?A.Because they just want to show that they are rich.B.Because they are better served in a luxury hall.C.Because there are too much complaints about small rooms.D.Because there are no other choices.71.What may happen to those who can’t afford the accommodation fee?A.They may borrow more money from the bank.B.They maygo to OIA for help.C.They may not go to college.D.They may go abroad for further study.CToday’s career assumption is that you can get a lot of development, challenge and job satisfaction and not necessarily be in a management role.Managing others is always a tough task, but in the past that stress was balanced by hopes for career mobility and financial rewards. Along with a sizable pay raise, people chosen as managers would begin a nearly automatic climb up the career ladder to successful executive private benefits: company cars, club memberships, plus the key to the executive washroom.But in today’s global and more competitive showground, a manager sits in an insecure (不稳定的)chair. More companies has begun to take less management as they come to view their organizations as collections of talents rather than hierarchies (等级). There are far fewer steps for managers to climb. Also, managerial jobs demand more hours and headaches than ever before but offer slim, if any financial paybacks and perks.Now managers must manage many people who are spread over different locations, even over different continents. They must manage across functions with, say, design, finance and marketing.In many companies, when the most praised people in business are those launching something new, management seems like an invisible, thankless role. Employers are looking for people who can do things, not for people who make other people do things.Moreover it may not pay to be a manager, at least not the way it once did. Ms. Chmielewski says, “The emotional rewards can be great, and there were times when I enjoyed management. But a 10-to-11-hour day and one weekend day a month is the norm (标准)”.With more people cautious of joining management, are companies being hurt or worrying about developing future leaders? Not many are. While employers have fired a lot of managers, they believe many more candidates linger on at many companies. “Another reason why companies aren’t short of managers,” argues Robert Kelley, a business professor, “is that so many workers today are self-managed, either individually or via teams, they don’t need a manager.”72.By writing the passage, the writer seems to _____.A. explain reasons for firing managersB. advise people not to become managersC. express dissatisfaction of some managersD. encourage managers to be more competitivepared with past, the managing job today is more _____.A. demandingB. rewardingC. questionableD. acceptable74.The author mentions what Ms Chmielewski says to reflect that _____.A.the managers’ low working efficiency makes them less paidB.the gain of being a manager is not as satisfactory as beforeC.she enjoys great emotional rewards of being a manager nowD.she misses the past enjoyment of being a manager75.What can we infer from the last paragraph?A.More and more people are eager to become managers.B.There will be more managers to be employed in the future.C.Employers think it easy for them to find managers in the future.D.Teamwork makes it possible for companies not to hire more managers.Section CDirections: Read the following text and choose the most suitable heading from the list A-F for each paragraph. There is one extra heading which you do not need.A.Take your vitamins.B.Remember to brush before bed.C.Wash your hair now and then.D.Get your protein.E.Walk it off.F.Eat good fats.It is very important to keep your hair healthy. Here are five ways for you.76. _____ Good fats are also called necessary fatty acids which the body can’t produce naturally. Eating these types of fats will help promote healthy skin, nails, teeth and hair. They can be found in the form of oil, or in food such as seeds, nuts and olives.77. _____ Hair is nothing more than dead protein. But that doesn’t mean that it is not important. A lack of it can cause slow growth and thinning, where on the contrary, getting enough amounts can help promotes growth. Good choices to include in the diet would be eggs, lean meats, tofu, fish, yogurt and beans.78. _____ There are a handful of vitamins that have been known to be effective for healthy hair. Some of the main ones include vitamin B, biotin, calcium, vitamins A, C and E, and iron. Other than in extra form, these nutrients can also be found naturally in citrus (柑橘类) fruits, peppers, low-fat dairy products, dried fruits, green vegetables and whole grains. A large salad can be made with the inclusion of a lot of these food.79. _____ Getting enough exercise can help promote hair growth. Circulation to the scalp isa very important factor for healthy hair and growth. Aim to get at least 20 to 30 minutes of exercise every day. It can be walking, jogging, weight training, biking or moderate intensity activity that is enjoyable and easy to fit into your schedule.80. _____ Right after you brush your teeth, brush your hair as well. Brushing hair fifty to one hundred strokes right before bed can help remove pollutants and dirt while also stimulating circulation. Also, natural oils are released, which will add more sheen (光泽) and oxygen to your hair.Section DDirection: Read the passage carefully. Then answer the questions or complete the statements in the fewest words.(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.) Every day we meet people in a number of business and social situations. And the way we meet and greet them creates an impression. It’s important to do so in proper way, no matterwhether you areintroducing yourself to someone, or introducing two people to each other. To keep you aware of this, we have gathered tips on how to make a proper introduction.✧Always stand when making an introduction.When you are seated and someone comes up to greet you, make the effort to stand up. By doing this, you show respect for yourself and for the other person.✧Always maintain eye contact while making an introduction.Many people are not aware of the value of this simple action. When you make eye contact you are giving a confident image.✧Always introduce a person of lesser authority to one of greater authority.The most important thing to remember is to say the most important person’s name first. For example, when introducing you supervisor to a job candidate, you would give your supervisor’s name first. “Bob Jones, may I introduce Susan Lee, who has just graduated from ABCUniversity?”✧In a situation where rank is unimportant, an introduction is based on sex and age.A man is presented to a woman and a younger woman to an older woman. What if you find yourself in a situation where you have forgotten the other person’s name? Start with a handshake and reintroduce yourself. By doing this, you will usually cause the other person to do the same. However, if the other person does not take your suggestion, it is OK simply to apologize and let the person know that you can’t remember her or his name. This is not the ideal situation, of course, but it doesn’t happen to all of us. The other person should be forgiving.81.When you are sitting and a person comes to you, hoping to talk to you, you should___________________________________.82.Why does a person need to maintain eye contact while making a conversation?_____________________________________________________________83.Who should you introduce first, your grandfather or your classmate?_____________________________________________________________84.If you forget a person’s name, you’d better_____________________________________________________________.第II卷I.
