2013年绵阳东辰国际学校高中招生考试13年语文试题(1)
2013年绵阳东辰国际学校高中招生考试语文试题(满分:80分,时间:55分钟)亲爱的同学们:四川高中前三强——绵阳东辰国际学校热烈欢迎你的到来,并由衷地为你即将“进一流高中,跟一流名师,创一流前途”而高兴!预祝你成功! 一、阅读(20分)读下列文章,完成1——4题。
清 欢林清玄(1)少年时代读到苏轼的一阕词,非常喜欢。
这阕词,写苏轼和朋友到郊外去玩,在南山里喝了浮着雪沫乳花的小酒,配着春日山野里的蓼菜、茼篙、新笋以及野草的嫩芽。
所以能深记这阕词,主要是爱极了最后的一句——“人间有味是清欢!” (2)那么,“清欢”是什么呢?(3)清欢,不同于“人生在世不称意,明朝散发弄扁舟”的自我放逐,不同于“人生得意须尽欢,莫使金樽空对月”的尽情欢乐,也不同于“人生不相见,动如参与商”的那种无奈。
当一个人感觉野菜的清香胜过了山珍海味,或者看出路边的石头也许比钻石更有魅力,或者觉得聆听林间鸟鸣比提笼遛鸟更令人感动,或者体会了静静品一壶茶比吃一顿喧闹的晚宴更能清洗心灵……他就懂得了“清欢”。
(4)我们活在这个世界上,领略过千百种人生。
可是,享受“清欢”就难了!尤其是生活在现代的人,差不多是没有清欢的。
(5)我们想在路边好好地散个步,可是人声车声不断地呼吼而过,一天里,几乎没有纯然安静的一刻。
(6)我们到馆子里,想要吃一些清淡的小菜,几乎不可得。
过多的油、过多的酱、过多的盐和味精已经成为中国菜最大的特色。
(7)我们有时只想和朋友啜一盅茶,饮一杯咖啡,可惜的是,心情也有了,朋友也有了,就是找不到约会的地方,即便是山中或海边。
凡是人的足迹可以到的地方,就有了垃圾、污秽和吵闹。
(8)我当学生的时候,有一位朋友住在圆通寺的山下,我们常常沿着上山的石阶,走走,坐坐,停停,看看。
我们顺手拈下山道两旁熟透的朱槿花,吸着花朵底部的花露,感觉清香胜蜜,心里遂有一种春天才会有的欢愉。
(9)后来,朋友到国外去了。
我又去了一趟圆通寺,寺院的门口摆满各种摊子。

秦汉、唐宋、明清中国建筑艺术基本保持和延续着相当一致的美学风格,即实践理性精神......。
世界各民族的主要建筑多半是供养神的庙堂,如希腊神殿、哥特式教堂等。
而中国的大都是宫殿建筑,供世上活着的君主们居住。
中国祭拜神灵在与现实生活紧紧相联系的世间居住的中心,而不在脱离世俗生活的特别场所。
中国建筑不重在给人强烈的刺激或认识,而重在生活情调的感染熏陶,它不是一礼拜才去一次的灵魂洗涤之处,而是能够居住或经常瞻仰的生活场所。
在这里,平面铺开的建筑的有机群体,实际已把空间意识转化为时间进程,就是说,不是像哥特式教堂那样,人们一下子被扔进一个巨大幽闭的空间中,感到渺小恐惧而祈求上帝的保护。
相反,中国建筑的平面纵深空间,使人慢慢游历在复杂多样的亭台楼阁间,在这个不断的进程中,感受到生活的安适与环境的和谐。
这种实践理性精神还表现在建筑物严格对称的结构上,严肃、方正,井井有条。
它不是以单个建筑物的形状体貌,而是以整体建筑群的结构布局、制约配合取胜,结构方正,逶迤交错,气势雄浑。
非常简单的基本单位却组成了复杂的群体结构,形成在严格对称中仍有变化,在多样变化中又保持统一的风貌。
由于主要是世间生活的场所,供游乐享受而不只供崇拜顶礼之用,从先秦起,中国建筑便充满了各种供人自由玩赏的精细的美术作品(绘画、雕塑)。
讲究斗拱飞檐,门、窗形式自由多样,追求色彩鲜艳。
《论语》中有‚山节藻棁‛、‚朽木不可雕也‛。
从汉赋中也可以看出当时建筑中绘画雕刻的繁富,‚金铺玉户‛‚重轩镂槛‛,是对它们的形容描述。
延续到近代,也仍然如此。
大概随着封建社会晚期经济生活和意识形态的变化,园林艺术日益发展。
显示威严庄重的宫殿建筑的严格的对称性被打破。

I knew she loved me; she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and daughter.They never happened. And a gulf opened between us. I was “too emotional(易动感情的)”. But she lived “on the surface”.As years passed and I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive me.I posted the letter and waited for her answer, none came.My hope turned to disappointment, then little interest and, finally, peace. It seemed that nothing happened. I cou ldn’t be sure that the letter had even got to Mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.Now the present of her desk told me that she was pleased that writing was my chosen work though she’d never been able to. I cleaned the desk carefully and found some papers inside —a photo of my father and a one-page letter, folded(折叠) and refolded many times.Give me an answer, my letter asks, in any way you choose, Mother, you always chose the act that speaks louder than words.36.

The scientific and medical communities(团体) are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延长) human life. But those communities and policy(政策) makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life.For the last few years, the genetic advances in the developing field of biotechnology(生物技术) have provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic code(密码) have opened a world of possibilities for human health, as well as for the popular imagination.While European and Japanese researchers are making rapid progress in decoding(解码) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal(致命的)diseases. Already, the Human Genome Project has become widely known and praised for finding the genes(基因) connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.46. Why did the scientists work hard at mapping the human genome?A. Because the human genome can destroy many illnesses.B. Because the human genome's completion can help them get rid of many diseases.C. Because they wanted to be better known than others.D.

The main idea of this article is about _______.A. unlocking genetic codeB. the genes' discoveryC. the great human genomeD. the genes and the scientistsDThe market is a concept(概念,观念). If you are growing tomatoes in your backyard for sale you are producing for the market. You might sell some to your neighbor and some to the local manager of the supermarket. But in either case, you are producing for the market. Your efforts are being directed by the market. If people stop buying tomatoes, you will stop producing them.If you take care of a sick person to earn money, you are producing for the market. If your father is a steel worker or a truck driver or a doctor or a grocer, he is producing goods or service for the market.When you spend your income, you are buying things from the market. You may spend money in stores, supermarkets, gas station and restaurants. Still you are buying from the market. When the local grocer hires you to drive the delivery truck, he is buying your labor in the labor market.The market may be something abstract(抽象的). But for each person or business who is making and selling something, it is very concrete. If nobody buys your tomatoes, it won’t be long before you get the message. The market is telling you something. It is telling you that you are using energies and resources in doing something the market doesn’t want you to do.51. Which of the following would be the best title of the passage?A. Selling and Buying.B. Everything you do is producing for the market.C. What is the market?D. What the market can do for you.52.

If you are growing tomatoes in your backyard for sale you are producing for the market. You might sell some to your neighbor and some to the local manager of the supermarket. But in either case, you are producing for the market. Your efforts are being directed by the market. If people stop buying tomatoes, you will stop producing them.If you take care of a sick person to earn money, you are producing for the market.

You may spend money in stores, supermarkets, gas station and restaurants. Still you are buying from the market.

But for each person or business who is making and selling something, it is very concrete. If nobody buys your tomatoes, it won’t be long before you get the message.
