我国文人画的长处就在于不单纯追求表面的形似,而重于表现作者对自然的主观情感和印象,借以抒发作者的心灵和情趣。
苏轼更是明确地提出了“论画以形似,见与儿童邻”的艺术主张。
在强大的文化影响下,文人把绘画变成文化的载体,要见才情、见学问、见人格、见风度。
与此互为因果的便是越来越成熟地追求诗、书、画、印在画面上的有机构成。
几种艺术样式融为一体,互相辉映,不仅能增加画面形式的美感,而且能使画面的内涵容量无限增加,具有补充和阐发画面内容的作用。
这种美的法则是中国文化的独特产物,是随着中国画发展到一定历史时期,知识分子走上画坛并且逐渐替代职业画家居主流地位而产生的。
苏东坡评王维:“味摩诘之诗,诗中有画;观摩诘之画,画中有诗。
”这句话奠定了文人画的理论基础。
诗与画结合有两层意思,即画上无题诗、书款,而有诗意,可谓诗、画意境的结合;画上有题诗、书款,诗画相配,相得益彰,使有限的画面包含无限的寓意。
画与诗尽管是两种不同的艺术形式,但从创作过程来看,在选材、艺术构思、表现方法等方面都有相似、相通之处。
画中有诗,其内在意蕴和抒情色彩就能丰富并提高画的意境。
从元代开始,画必题诗、书款,至明清更甚。
王冕所绘《墨梅图》中梅枝遒劲盘郁,冷傲孤高而生机盎然,其题诗云:“吾家洗砚池头树,朵朵花开淡墨痕。
不要人夸好颜色,只留清气满乾坤。
”经此诗一点,作者傲兀脱俗的气质以及生活理想和高尚情操跃然纸上,极大地拓展了作品的美学境界。
文人画的书画结合也有两层意思:一是文人画家兼擅书法,追求以书入画;二是诗文题跋要与构图密切配合,以求书画结合的形式美。
书、画本不同体,但是在中国传统文人的手中却同出一法。
随着书法艺术的全面繁荣,文人作画自觉不自觉地以书入画。
普通高等学校招生全国统一考试地理试题(上海卷,解析版)【试卷总评】该套试题总体难度适宜,整体而言,命题的基本要求仍然与保持不变。
第一,以高中系统地理为主的内容格局不变。

However, only a few people know that the story is really a pack of lies. Let me explain.About a hundred or so years ago there was a hotel owner in Wales who was fed up with business being so bad. His hotel was stuck in the middle of nowhere and hardly anyone came to stay. Then, one day, he had an idea. A famous prince called Llewellyn had lived in the area during the Middle Ages and had been keen on dogs. This is hardly surprising as hunting was extremely popular at that time. So what he did was to make up the story of the brave and faithful Gelert and how he had been killed by his ungrateful master.Of course, people would be far more likely to believe the story if there was something they could see. So one day, the hotel keeper went to the top of a high hill and built a sort of monument from the stones he found lying around A friend of his, who was an accountant, helped him to construct it .The "tale" soon caught on and developed a life of its own. Afterwards, people came from far and wide to see the spot where the dog was buried. Needless to say, business became very good for the hotel owner.65. According to the tale, the dog was killed by ___.A. a hotel ownerB. a famous accountantC. its masterD. the prince's son66. The owner of the hotel successfully improved his business by ___.A. making up a storyB. constructing a hotel on the hillC. showing people around his hotelD. inviting a friend to help him67.

A Prince and His DogB. A Profit - Making LieC. A Magnificent HotelD. A Faithful but Unlucky Dogsummer, join the International Conservation Scouts on a fun - filleddifference. Year after year, young people from all around the world get together at one of our sixteen 环境保护) camp. Their shared aim? To help protect the countryside and its wildlife.Many animals and plants are in danger of disappearing forever. The dormouse, a kind of mouse, needs woodland plants for food and trees to stay in. Its habitatdestroyed by man and it needs our help to survive.69. The main purpose of this passage is ___.A. to offer young people a fun - filled holidayB. to attract young people to attend a conservation campC. to persuade people into exploring the countrysideD. to raise funds for the International Conservation Scouts70. According to the passage, you can ___ at the conservation camps.A. experiment on the dormouseB. practise your favorite hobbiesC. enrich your knowledge of wildlifeD. have free accommodation and food71. Judging from the writing style of the passage, it is ___.A. a piece of advertisementB. a science reportC. a passage for professional readingD. a passage for arguing an opinion( C )In some children who go blind, certain parts of the brain that normally control vision appear to switch jobs and focus instead on sound, a new study has found.The study, by researchers at the University of Montreal, involved 7 adults who could see and 12 adults who had lost their vision when they were children. Each participant sat in a room with 16 loudspeakers at different locations. The room was designed so that there were no echoes. During the experiment, the speakers irregularly produced sounds. Participants had to point to where the sounds were coming from. Meanwhile, the researchers monitored blood flow in the brains of the participants to see which brain structures were working during the task.The results showed that five of the blind participants were very good at pointing to where sounds were coming from. In these people, blood flow increased in the visual cortex- an area at the back of the right side of the brain. This part of the brain is usually associated with vision.The other seven blind participants showed no increase in activity in the visual cortex. These people didn't do very well at picking out where sounds were coming from. Now, the researchers are looking at whether these people have gained an enhanced sense of touch instead of sound to replace their lostvision.The scientists say that their study shows how adaptable parts of the brain can be.72. The purpose of the experiment described in the passage is to find whetherA. blind children can regain their sightB. blind people have a better sense of soundC. the sense of touch is better among blind peopleD. blood flow in the brains of blind people is slower73. The participants of the experiment were asked ___.A. to tell the difference between 16 soundsB. to take down the time each sound lastedC. to identify the direction the sound came fromD. to detect the number of the loudspeakers.74. During the experiment, blood flow in the brains of the participants was measured in order to ___.A. learn about the way they react to echoesB. look for the way of enhancing hearing abilityC. find which parts of the brain were functioningD. expose the relationship between seeing and touching75. Which of the following statements best summarizes the main idea of the passage?A. Most blind people have a well - developed sense of touch.B. People go blind because of the breakdown of their visual cortex.C. Most blind people have a better sense of sound than normal people.D. Human brains can adjust themselves after the loss of a certain function.(D)Indian's snake charmers are to be retrained as wildlife teachers under a plan to prevent their unique skills and knowledge from being lost. The charmers, who make snakes dance to the sound of flutes(笛子), used to be a traditional feature of Indian life, performing in towns and villages, until they were banned in 1972 to control the trade in snake skins.The government is now considering a plan to train the saperas, as they are known, to visit schools and zoos to tell children about forests and wildlife. There is also a proposal to set up a “dial a snake charmer” service to help householders to deal with unwelcome intruders.“For generations they have been a feature of Indian life but now they can't earn a living for fear of arrest,” said Behar Dutt, a conservationist behind the plans, “if a policeman doesn’t catch them, animal rights activists report them.”Many snake charmers have continued to work clandestinely since the ban, despite the threat of up to three years in jail. But their trademark cloth-covered baskets, hung from a bamboo pole carried across their shoulders, make them an easy target for police.The fate of Shisha Nath, 56, from Badarpur, a village just outside of Delhi, is typical of practitioners(从业者) of the dying art. “I used to earn enough to support my family and send my children to school, "he said. "Now it's hard to earn even f, 1 a day. My children want to be snake charmers. It’s our identity. We love the work. But it s become impossible.Ne xt month Dutt’s project to train 30 snake charmers will begin at a snake park in Pune, western India, where experts will enrich their home-grown skills with some formal knowledge.More than the law, though, it is the dishonest attitude of their fellow countryman that angers many snake charmers."'We're disturbed all the time but when people want a snake removed from the house, they rush tous," said Prakash Nath, who was ordered recently to the home of Sonia Gandhi, the Congress party leader.76. According to the passage, snake charmers will be retrained as wildlife teachers mainly because___.A. schools need large numbers of such teachersB. most of them cannot support their familiesC. their performances on the street are bannedD. the government plans to save the dying art77. The purpose of the proposed "dial a snake charmer" telephone service is ___.A. to give performance of snake dancingB. to teach householders how to catch and kill snakesC. to offer cleaning service to wealthy householdersD. to help remove unwanted snakes from the houses78. The word "clandestinely" in paragraph 4 can be best replaced by the word "___"A. secretlyB. publiclyC. subconsciouslyD. diligently79. Which of the following statements is NOT true according to the passage?A. Snake charmers can easily be recognized by the police on the street.B. Children of snake charmers would not like to continue their fathers' job.C. Snake charmers are quite angry with the attitude of their fellow countrymen.D. The animal rights activists take a negative attitude towards snake charmers.( E )Directions:Read the following text and choose the most suitable heading from A-F for each80. ___If you suddenly received a lot of money, how would you spend it? For the people of Tuvalu, a tiny state comprising nine islands in the South Pacific, something unusual happened. In 1999 Tuvalu, with its population of 11,000,was the third poorest state in the world. Later, Tuvalu received a domain name on the Internet ——the letters “.tv”. A communication company from California quickly offered to buy the domain name for $ 40 million. The islanders became very rich.81. ___At the same time the islanders received some very bad news. Due to global warming, and because the islands are only 3m above sea level, Tuvalu will probably become the first state in the world to disappear under the sea. According to scientific estimates, the islands will suffer severe floods within the next 15 - 20 years, and by the end of the century, the islands will have disappeared from sight altogether.82. ___You can already see signs of the rising sea on Tuvalu. Pools of seawater appear here and there, some beaches are swallowed by the waves, and the roots of trees are rotting by the ocean. The rains cause temporary floods.83. ___But despite these problems, the Tuvaluan had their new money. Paul Lindsay, a documentary film - maker, went all the way to Tuvalu, and came back with an incredible story. As the water rises, the Tuvaluan are using the money to develop the land that is soon to disappear. They are building new houses, planning nightclubs, restaurants and hotels, and new cars are driving around on new roads. "Just because we are sinking, it doesn't mean we don't want to raise our standards of living." Lindsay was told by Sam Teo, Tuvalu' s minister for natural resources.84. ___Of the $ 40 million Tuvalu received through the Internet deal, $ 10 million was used to asphalt the islands' L9km of roads. Before 1999 there were four cars on the islands. The Tuvaluan used to walk or cycle everywhere. There was a flood of imported foods and goods and soon these had unexpected consequences. The Tuvaluan people now suffer from diseases such as obesity, high blood pressure and diabetes. Others discovered that it was too expensive for them to keep their cars. There is now a huge rubbish dump in the middle of this tropical paradise, covered with abandoned cars and other waste.第II卷(共45分)I .

一、现代文阅读(35分)(一)现代文阅读I(本题共5小题,19分)阅读下面的文字,完成下面小题。
对素食者和肠胃疾病患者来说,藜麦的发现是一个奇迹。
藜麦不含麸质,富含镁和铁,比其他种子含有更多的蛋白质,包括人体无法独自生成的必需的氨基酸。
美国宇航局宣布,藜麦是地球上营养最均衡的食物之一,是宇航员的理想之选。
产于安第斯山的藜麦有一个令西方消费者神往的传说:印加人非常重视藜麦,认为它是神圣的,并且称之为“万谷之母”。
不过,藜麦的爱好者却通过媒体发现了一个令人不安的事实。
从2006年到2013年,玻利维亚和秘鲁的藜麦价格上涨了两倍。
2011年,《独立报》称,玻利维亚的藜麦消费量“5年间下降了34%,当地家庭已经吃不起这种主食了,它已经变成了奢侈品”。
《纽约时报》援引研究报告称,藜麦种植区的儿童营养不良率正在上升。
2013年,《卫报》用煽动性标题提升了人们对这个问题的关注度:“素食者的肚子能装下藜麦令人反胃的事实吗?”该报称,贫穷的玻利维亚人和秘鲁人正在食用更加便宜的“进口垃圾食品”。
《独立报》2013年一篇报道的标题是“藜麦:对你有利--对玻利维亚人有害”。
这些消息传遍了全球,在健康饮食者之中引发了一场良心危机。
在社交媒体、素食博客和健康饮食论坛上,人们开始询问食用藜麦是否合适。
这种说法看似可信,被许多人认可,但是经济学家马克·贝勒马尔等人对此则持保留意见。
毕竟,藜麦贸易使大量外国资金涌入玻利维亚和秘鲁,其中许多资金进入了南美最贫穷的地区。
几位经济学家跟踪了秘鲁家庭支出的调查数据,将种植且食用藜麦的家庭、食用但不种植藜麦的家庭和从不接触藜麦的家庭划分为三个小组。
