2016年高考(94)江西临川一中2016届高三第一模拟考试江西省临川一中2016届高三第一模拟考试语文试卷第卷阅读题一.现代文阅读(9分,每小题3分)阅读下面的文字,完成1~3题。
意境论的重生意境是中国美学的核心概念从历史上看,西方美学长期专注于对美的研究。
尽管18世纪后,一些西方美学家开始将研究对象调整为趣味或感性认识,19世纪后有用审美经验研究来取代美的研究的趋势,20世纪后关于艺术定义的争论占据了美学的大部分内容,但是,从总体来看,在两千多年的历史中,美可以说是西方美学的核心范畴。
什么是中国美学的核心范畴?有些研究者认为,美既然是西方美学的核心范畴,它也应该是中国美学的核心范畴,就像其他科学或学科的情形一样。
于是,他们以美为线索到卷帙浩繁的文本中去寻找美的思想。
结果令人失望,他们期待的深刻且丰富的美的思想并没有被发现。
这与中国独特的艺术传统和丰富的艺术宝库很不相称。
按理,不应该出现这种美学理论与艺术实践不相匹配的情况。
20世纪上半期活跃的美学家王国维、邓以蛰、宗白华等人发现,中国美学的核心范畴可能不是美,而是意象、意境、气韵等独特概念。
通过这些概念,他们发现了辉煌灿烂的中国美学宝库。
意境使人超越有形的局限中国美学的核心概念不是美而是意境,这一点已经成为中外学者的共识。
那么,什么是意境?它与美相比,究竟有何不同?对于这个问题,既可以通过追溯中国美学史来回答,也可以通过与西方美学的比较来回答。
从中国美学史来看,意境与意象和象等概念相关。
在《易传》中,象是与形对照起来界定的:在天成象,在地成形见乃谓之象,形乃谓之器。
象与形相比,有虚与实、动与静的区别。
象比形更虚灵、更生动。
象还有另外一个用法,类似于现代汉语中的想象。
《韩非子·解老》中对象做了这样的解释:人希见生象也,而得死象之骨,案其图以想其生也。
故诸人之所以意想者,皆谓之象也。
比较起来说,眼见的形为实,意想的象为虚。
正因为想象的介入,象变得更加虚灵、生动和非现实。

You might like to try one of these four experiences. Crocodile watching Do you fancy getting up close to some of the most terrifying animals on earth? Crocosaurus Cove, in Darwin (Australia) has the ―Cage of Death‖. It’s an enclosure that’s lowered into a pool. This gives you a 360 degree view of a crocodile as it’s being fed. The cable broke once and the cage sank to the bottom, but they’ve fixed it since then. EdgeWalk How about walking along the edge of a building several hundred meters up in the air? If that sounds like fun, head off to the CN Tower in Toronto (Ontario, Canada). Built in 1976, the tower is 553.33 meters tall. The EdgeWalk consists of a 20-30 minute stroll along a 1.5 meter wide platform that runs around the tower’s restaurant roof. During the walk, you’re encouraged to lean forwards as you look over Toronto’s skyline (轮廓线). Plastic ball rolling Do you fancy rolling down a hill in a plastic ball? Plastic ball rolling is popular all over the world, but the place to give it a go is in Rotorua (New Zealand). 临川一中、临川一中实验学校2016届高考第二次模拟考试英语试卷 第 3 页 (共 8 页)
Brother David and Andrew Akers came up with the idea in 1994. A typical orb (球) is about 3 meters in diameter, with an inner orb size of about 2 meters. There’s no brake or steering mechanism, but the inner layer of the plastic ball helps absorb the shock. Volcano bungee jumping If you’re looking for the adventure of a lifetime, how about going bungee jumping off a helicopter into the crater of a live volcano? As part of the jumping, a helicopter ride takes you to the Villarrica volcano, one of the most active in Chile. Once you’re at the drop zone, you leap off the helicopter and fall into the volcano. Finally, you enjoy the ride back to the airport flying at 130kph. Attracted by the above? If so, please contact us. Only half price from March 22 to April 25th For more information, please click here. 21. According to the passage, there was an accident once when people _____. A. jumped into the Villarrica volcano B. walked along the platform of the CN Tower C. rolled down a hill in a plastic ball in Rotorua D. watched crocodiles in the ―Cage of Death‖ in Darwin 22. Which of the following was first invented in New Zealand? A. EdgeWalk. B. Crocodile watching. C. Plastic ball rolling. D. Volcano bungee jumping. 23. It can be inferred that all the four experiences are ______. A. interesting sports B. exciting and extreme C. held on high places D. fit for middle to old people B I used to think that life in Jim Thorpe, Pennsylvania, was filled with never-changing routines. I hated that everyone seemed to know everything about everyone else. Everyone seemed to enjoy talking about other people and their lives. I also didn’t like the fact that people seemed very close-minded. I felt trapped. I felt like I was missing out on opportunities. It seemed to me that city life would be the opposite. Then I took my first trip to New York City. I couldn’t wait to experience the city. However, when I arrived in the Big Apple, it wasn’t at all what I had imagined. I knew it was home to thousands of people, but I hadn’t had the least expectation to see so many people on the street at one time. All the streets were filled with people. I also felt a little surprised to see that everyone was in a hurry and everything moved at such a fast pace. When I took the subway for the first time, I said hello to the middle-aged woman next to me. She looked at me with dislike and didn’t say a word. After just one day, I realized how important my small town is to me. Now I appreciate the familiar faces I see every day. I like the feeling of security and belonging my town offers. Jim Thorpe gives me a sense of community and togetherness that the city doesn’t provide. I realize just how much a simple hello does for a stranger — it really can make your day a little better. My big trip showed me that my small town really has instilled(注入) morals and values in me that I didn’t even know I had. I would never have known what a big place my town holds in my heart if I had not taken that trip to New York City. 24. How did the author feel about life in Jim Thorpe at first? A. People there cared little about others. B. People there liked to accept new things.
