24．甲骨文有以形表意的特征。

图7中的“城”字中间的方形小框，表示四周的城墙，表示城楼，为士兵守护之意；“邦”字下边的“田”字，代指疆域土地，上半部分的象形符号，是标示疆界范围的界标。

从这两个字的结构和含义可以看出，“城邦”的含义和主要功能是“城”“邦”图7A．一定区域范围内统治管理中心B．具有对外防御能力的军事基地C．强化农业生产为主的经济中心D．土地和军队是国家财富的来源25.江南土豪从汉魏以来既已存在，并随着江南经济的进步而有较大规模的发展，在刘宋时期他们中就不乏“献私财数十万”以求升进者，但迄至梁末，他们并不能“预于南朝大政”，究其原因A.军功授爵排斥纳粟拜爵B.唯才是举一定程度规避门阀士族C.新兴地主缺乏武装力量D.九品中正制形成僵化的门阀制度26.据《建炎以来系年要录》记载：宋高宗谕大臣……曰“广南市舶（市舶司，为掌管海外贸易征税、管理外商及收购舶来物货的官署），利入甚厚，提举官宜得人而久任。

”据此可知宋代A.外贸收入用于国计民生B.外贸税收成为政府财政主要来源C.市舶事务需要专人掌管D.广州成为最主要的对外贸易口岸27.“商籍农而立，农赖商而行，求以相辅，而非求以相病……遁其有无，官民农商，各安其所而乐其生，夫是以为至治之极”。

与此观点相似的是A. “黄金珠玉，饥不可食，寒不可衣”B. “生民在勤，所宝惟谷”C. “工农商虞本为一体，皆富民之政”D. “国以人为本，人以衣食为本”28. 马克思曾说：“英国的入侵……摧毁了印度原有的经济基础，解构了那些半野蛮半原始的社会结构……虽然对此我们会心怀悲伤，但是我们一定不能忘记，正是这些看起来平和的田园牧歌式的乡村社会结构构成了东方专制主义最坚实的基础，它极大地禁锢了人类的思想。

AI’ve often wondered if I might do more good as a travel agent rather than as a psychologist. It seems that I have been more dramatically affected by certain kinds of travel experiences than I ever have.My trip to Iceland is a fine example of that. The plan was to spend two days in a remote mountain hut in Iceland. I was working on a photographic book about winter in Iceland and needed to capture images of this amazing region of high mountain peaks, smoky volcanoes, and lakes with floating icebergs.The moment after we arrived, the weather turned extreme making visibility impossible. It snowed so much and the wind bl ew so hard that we couldn’t leave the tiny hut. To stay warm, we walked around in circles much of the day inside the tiny hut. We tried to call for help but the radio did not work. Day after day, we watched our supplies of food and fuel grow dangerously short. We got acute cabin fever (幽居病) and started going for walks and ski expeditions outside. Even when the weather finally broke, nobody came to get us even though it was three days beyond our scheduled pickup. By the time the rescue team came to pull us out, we had all given up hope.From then on, the world looks different to me, as does my life. It would have taken me years of psychotherapy to get to the same point.Almost everyone has a story to tell, and interestingly, most of these experiences were not altogether pleasant at the time. In fact, it appears that the most constructive life-changing journeys were those that involved some sorts of awful and uncomfortable events that forced the person to develop new resources, increase confidence, and solve problems in new ways.21. The writer went to Iceland to ______.A. enjoy the natural beautiful floating icebergsB. take photos about the region for a bookC. collect materials for psychological researchD. challenge the high mountains there22. During the trip in Iceland, those travelers faced difficulties EXCEPT that ______.A. they got lost in the mountainB. they were short of food and fuelC. they couldn’t see the surroundings clearlyD. they failed to get in touch with the rescue team23. From Paragraph 3, we learn that the travelers ______.A. were in despair before they were rescuedB. stayed in the hut for three days altogetherC. got sick because of going for ski outsideD. got rescued immediately the weather turned fine24. Which of the following statements is true according to the passage?A. The writer is a travel agent who loves difficult challenges.B. In Iceland the weather is always extreme and it snows a lot.C. The travellers were so depressed that they needed psychotherapy.D. Awful journeys may become life-changing events that inspire people.BOne of India’s top engineering schools has restricted Internet access in its boarding houses, saying addiction to surfing, gaming and blogging was affecting students’ performance, making them lonely and even suicidal.Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them. “Now, a student doesn’t even know who lives two doors away from him because he is so busy on the Internet,” said Prakash Gopalan, dean of Student Affairs. “The old dormitory culture of companionship and socializing among students is gone. This is not healthy in our opinion.”IIT-Mumbai, with about 5,000 students, is one of the seven IITs across India which are considered to be among the finest engineering schools in the world. They are also a talent pool for global technology giants. But their hard courses, tough competition and lonely campus lifestyle have taken an effect on students. Depressive and dysfunctional lifestyles are known to be common among IIT students, and at least nine have committed suicide inthe past five years. Students have unlimited free Internet access in their boarding houses to help them in their studies, but many also use it to surf, chat, download movies and music, blog and for gaming.“Starting Monday, Internet access will be banned between 11 p.m. and 12:30 p.m. at IIT­Mumbai’s 13 boarding buildings to encourage students to sl eep early and to try and force them out of their shells.” Gopalan said. But the move has not gone down well with students who say they hate their lives being regulated. “Now they will say we need to listen to a lullaby (摇篮曲) to go to sleep.” said Rajiv, an electronics student.25. According to the text, the students addicted to the Internet in IIT-Mumbai are likely to ______.A. perform well in studiesB. participate in social activitiesC. know their classmates betterD. feel lonely and even suicidal26. The underlined word “dysfunctional” in Paragraph 3 most probably means “______”.A. unpopularB. meaningfulC. abnormalD. exciting27. What measures have been taken in IIT-Mumbai?A. Students must go to bed before 11 p.m.B. Students are forbidden to surf the Internet on campus.C. Students have unlimited free Internet access in their dormitories.D. Internet access is unavailable in deep night in boarding buildings.28. We may infer from the last paragraph that ______.A. all electronics students hate the banning orderB. some students complain about the banning orderC. there is no Internet access on the IIT campus ever sinceD. more students prefer listening to music to surfing the InternetCWell, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It’s awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.It may sound risky, so many teens stay wi thin their own social circles to find rides, and don’t branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.“I think the digital connection of y oung people is really key, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they’ve been very used to sharing,” said Juliet Schor, a sociology professor at Boston College.The sharing economy got big during the recession (经济衰退), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, “The symbol of freedom isn’t the car any more because there’s technology out there connecting you to a car.”According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver’s license compared to six in ten today. So it’s not that surprisin g that on my 16th birthday I wasn’t rushing to get a license but an iPhone.“Driving, for young people, does mean they have to disconnect from their technology, and that’s a negative. So if they could sit in the passage side and still be connected, that’s going to be a plus.” Schor continued.To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.29. The American teens like me, prefer to possess an iPhone as a birthday gift because _______.A. it is most fashionable and coolB. they are bored with driving carsC. they are fond of being connectedD. it is much cheaper than a car30. We can learn from the text that _______.A. Twitter is a website for teens to make friends and achieve goalsB. ridesharing can be seen as a sign that people still count on each otherC. driving cars for teens means a plus and connecting with technologyD. having a car and cost-sharing symbolize more fre edom for the author’s mother31. Professor Juliet would agree that _______.A. young people will sit waiting to be contacted by reading a passageB. sharing economy is bound to be responsible for the recessionC. young people tend to share a car with strangers by means of TwitterD. being connected via technology comes first for young people32. The best title for the passage is probably _______.A. Twitter, an Awesome WebsiteB. Cars or iPhoneC. Teens Use Twitter to Thumb RidesD. Cool Teens on the GoDNews that Microsoft made a $44.6 billion bid to buy Yahoo resulted in heated discussions made by many Internet users. Here are some responses:Diane Burke of Weeks bury, KentuckyI think it would definitely be an interesting combination. Everyone recognizes the names Yahoo and Microsoft, but everyone also says, “Did you Google it?” Such a catchphrase (时髦话) is going to be hard to beat. Shaun Carney of Laurelville, OhioI think the merger (合并) will provide more competitions for Google. I don’t think the merger will allow Microsoft to develop faster than Google, though. I believe the increased competition this merger brings will force Google to stay on top of its game by offering more fresh and original Internet tools and expanding on the tools it already offers.Toni Suarez of Hacienda Heights, CaliforniaI view the merger as a necessary element in preventing a monopolization (垄断). Perhaps it would bring better high technology innovations to e-mail and help in researching and developing a better Internet!Rick R. of Edgewater, FloridaIt sounds like a disaster to me. If this were to happen, I would stop using my Yahoo e-mail account because I don’t like the feeling of Microsoft spying upon my business. I will sign up for Google.Antonio Glosser of Kansas City, MissouriRight now, Yahoo offers a lot of features and tools at no cost for all different levels of Internet users. Micr osoft seeks nothing but profit. Undoubtedly, they’ll do nothing other than find ways to start removing Yahoo’s formerly non-priced features. Microsoft’s greed will ruin the great thing that Yahoo currently is.33. How many companies are mentioned in the passage?A. One.B. Two.C. Three.D. Four.34. Which of the following statements is NOT true according to the passage?A. Shaun’s attitude towards Google is passive.B. Toni believes the Internet will have a promising future.C. Rick will support Google after the merger.D. Antonio is afraid that the merger will cost Yahoo’s free features.35. The passage is mainly about ______.A. opinions on the merger of Yahoo and MicrosoftB. the strengths of Yahoo and MicrosoftC. the strengths and weaknesses of large companiesD. the future of Yahoo and Microsoft第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

2014年东北三省三校高三第二次联合模拟考试（语文）高考语文2014-04-14 1151()2014年高三三校第二次联合模拟考试语文答案一、1．C（因果倒置。

原文第一段中提到：“东方主义” 建构成一种优劣对比的知识体系，通过教育、媒体以及留学生，向全球扩散，它最严重的后果，就是弱者会被教育得产生“自认劣等意识”。

）2．B（“经济的改变要以权力的改变为前提”错，原文“经济的改变需要权力的改变”，结合本段内容可知，是说东方在经济改变之后，寻求有权力的改变，才会有东西方的关系的改变，“东方主义”才能终结。

）3．C（A项“看似困难，实则容易”是对原文的错误理解。

B项“使中国人不再有”“并能够”都过于绝对。

D项“要真正实现不同民族之间的相互尊重”不正确，原文是“要真正实现对异文化的尊重”，可见文章强调的是“西方”对“东方”，不是“相互”的，“异文化”说成“不同民族”是偷换概念。

）二、（一）4．D（致：送给）5．C (①⑤⑥和“利”无关)6．A（A项三人表现不是截然不同的，凸显性格的说法也不对。

韩康子、魏桓子满足了智伯索要土地的要求，而赵襄子没有。

）7．（1）智伯说：“你怎么知道的？”絺疵回答说：“我看见他俩看我很仔细，然后快步跑开，那是知道我识破他们心思的缘故。

”（何以：凭什么，怎么， 1分；其：他们，他俩，1分；趋疾，快步跑开，1分；故：原因，1分；句子通顺，2分）（2）智伯军队为救水淹而大乱，韩、魏两军从侧面攻击智伯军，赵襄子带领士兵从正面迎击。

（翼：从侧面，1分；将：带领，1分；句子通顺，2分）（二）8．①听觉角度。

角声催促，鸟还未被惊醒，邻户的鸡已啼鸣，这是凌晨在驿站客舍听到的情景，点明题中的“晓”字。

（2分）②视觉角度。

连绵村庄，晨烟未散，行人起，丛林中残月在天，这是晓行所见的情景。

（2分）③感觉角度。

眼泪被寒霜微微凝结，为御寒而喝的酒，还不够抵抗天气的寒冷，这是写晓行的感触和感受。

（2分）9.这首词表达了思乡怀人的惆怅和羁旅漂泊的倦怠。

为什么教育不能产业化教育究竟能不能产业化?教育的确在一定程度上具有与私人产品相同的属性，比如这种产品的消费也具有一定的竞争性、排他性，并且，受教育者可以通过教育得益，例如增加工资收入、提高社会地位、获得精神享受等，其教育花费也就等同于私人的一种投资。

从这个意义上讲，教育具有商品属性，可以定价，可以买卖。

但是，教育同时具有公共产品的基本属性——社会公益性。

受教育者通过教育可以获得个人的种种直接收益，但受过良好教育的公民无疑可以给全社会带来广泛的收益，包括生产力的提高、社会文明程度的进步等等。

正因教育消费有溢出效应，也就是公益性，所以，经济学把教育定义为“准公共产品"，而不是私人产品。

这早已成为世界性的共识，成为世界所有国家主要由政府举办教育事业的最重要的理论根基。

1 999年10月联合国教科文组织在巴黎召开了首次世界教育大会，大会一致认为“市场规律和竞争法则不适用于教育。

教育不是经济的一个分支。

教育过程、教育目标、教育结果或t教育产品'都不能与经济相提并论"。

Students from the University fo Georgia will help run the aquarium and conduct research at the animal hospital.The aquarium was paid for almost completely by a $ 200 million gift from Berne Marcus, co-founder of Home Depot Inc, and his wife, Billi.”It’s going to be the mo st unique aquarium in theworld ,”said Marcus, Marcus said the aquarium was a “thankyou”note to the city of Atlanta and the State of Georgia, where the Home Depot first opened for business.68．According to this passage，Ralph and Norton are ．A．polar bears B．whalesharks C．penguins D．dolphins69．The world’s largest aquadmis located in．A．Los Angeles B．New York C．Atlanta D．Miami70．Which of the following is TRUE?A．The aquarium was designed to look like a giant shark．B．The aquarium’s giant tanks can hold eighteen million gallons of waterC．Ralph and Norton arrived in June，2005 from Japan．D．Marcus helped to build the aqualium to show his thanks to Atlanta．71．By saying”We want to be the world’s most engagingaquarium”Jeff Swanagan means．A．the aquarium will attract alarge number of visitorsB．the aquarium will be home to very special sea animalsC．the aquarium will be rebuiltand will be made even largerD．tlle aquarium will be the largest habitat for sea lifeEI llegal removal of coral(珊瑚)along Sri Lanka’s coastine increased the amount of destruction on the island by last December’s tsunami, say researchers.Harindra Femando, a fluid dynamicist(力学家)at Arizona State University in Tempe, made the connection after a visit to his native Sri Lanka earlier this year. While serving as a scientific expert and translator for a BBC-documentary team, he chatted with locals who said they saw the tsunami turn sideways when it hit coral-which would have made it less powerful than in coral-free areas. Fernando linked this to trucks he had seen last year carring piles of coral away from the sea.Using the eyewitness reports, estimates(估算) of wave heights, and a series of divers to check the persence or absence of corals, Fernando and his colleagues produces a map of coral gaps and wave flooding along Sri Lanka’s southwest coast.The tsunami reached significantly farther inland through the gaps;in one instance, the water travelled 1.5 kilometres long and knocked a passenger train off its tracks, killing 1,700. But only a few kilometers away, where the coral was still undamaged, the wave travelled just 50 metres inland and caused no deaths,There is a similar phenomenon. In Nicaragua in 1992,a tsuanmi poured through a break in the coral reef made ot let boats through,”Within this passage, water went one kilometre inland,”says Fernando.”But nearby, where the coral was undamaged, there were still beach umbrellas standing.”In Sri Lanka, coral is illegally mined to provide souvenirs for toursits, or to be used in house paint. Coral harvesters sometimes blow it up with dynamite(炸药)in order to collect fish at the same time. Often, the reefs in the best shape are those in front of hotels, as the hotel owners maintain them for the tourists, Fernando hopesthat his findings will encourages the Sri Lankean government to enforce(实施) its laws against coral mining.72．Harindra Fernando did all the following EXCEPT ．A．serving as a translator for a BBC-documentary teamB．helping the Sri Lankang overnment enforce its laws againstcoral miningC．producing a map of coral gaps along Sri Lanka’s southwest coastD．linking the coral removal with the destruction of Tsunami73．The main idea of Paragraph 5 is that ．A．undamaged coral can greatly decrease tsunami damageB．coral-free area is a danger to passenger trainsC．in general,water travels 30 times farther inland in acoral-free areaD．it is urgent to enforce laws against coral mining74．Which of thefollowing may NOT be the cause of coral gaps?A．Boat passages． B．Tourists’sight seeing．C．Fish collecting D．Tourists’souvenirs75．Which of thefollowing would be the best title for the passage?A．Harindra Fernsndo,a Great Environment ProtectorB．Stop Using Coral as SouvenirsC．Coral Cried”Help!Help!”D．Coral Mining Enhanced(加剧)Tsunami Damage非选择题(共35分)第四部分写作(共两节，满分35分)第一节短文改错(共2014小题；每小题1分．满分2014分)此题要求改正所给短文中的错误。

She has dozens of wine glasses already.M: Here’s an usual gift—a beautiful Chinese teapot. And it’s not expensive at all. It’s only $10.45. Do you think your mother would like it?W: It’s hard to make up my mind. But I think this is a good choice. Thanks for helping me.10.Some time ago, a friend of mine who worked in a part of the city I didn’t know very well, invited me to call on him. It took me hours to get there and I took great trouble to find a proper spot to park my car. As I was already three-quarters of an hour late, I parked my car quickly.At noon, just as I was l eaving my friend’s office, it suddenly struck me that I had no idea where I had parked my car. I could hardly go up to a policeman and tell him that I had lost a small green car somewhere ! Walking down street after street, I examined each car closely and was very happy to see a small green car just behind an old car. But how disappointed I was to discover that though the car was exactly like my own, it belonged to someone else! Feeling quite tired now, I went off for lunch. Some time later, I left the restaurant and walked down the street. Turning the corner, I nearly jumped for joy: my car was right in front of me, and there was no problem this time.To tell the truth, driving in crowded cities is far from being a pleasure and it is much easier to walk than to drive.11。

I am planning to apply for the Cambridge Summer Session 2014. Now I’m writing to ask several questions concerned.Firstly, I’m curious to know about the courses. How many courses will you offer in all and what subjects will it cover? Since I major in English, I would very much like to take some courses related to English literature and culture. I also want to know the schedule of these courses to see whether I’ll have time to visit other places in Britain on weekends. So I would appreciate it if you could forward a course plan to me?Secondly, do you provide boarding during the Summer Session? Are all the students living on campus or will you arrange home-stay?Thank you in advance! Looking forward to your reply!Yours sincerely,Li Hua。
