(18分)①在所谓文学边缘化的时代,韩寒,这个戏谑、调侃的高中辍学青年,这个以赛车手为职业的业余作家,像这个戏剧性时代的一个戏剧性神话:他的博客点击率,已经超过4.5亿人次;在2009年,他被多家媒体选为“年度人物”;在2010年,他被《时代周刊》选为“全球最具影响力100人”,被《外交政策》选为“全球百大思想家”。
有人据此认为,。
②和郭敬明相比,韩寒展示了“80后写作”另一种可能性。
在韩寒戏谑、尖刻的追问中,郭敬明营造的“幻城..”⑴烟消云散,逐渐展现出冰冷的真相——“80后”一代依然生活在历史之中。
如果说,郭敬明的写作是“小时代”写作,那么韩寒的写作则是对抗“小时代”的“大时代”写作,通过对于一系列热点新闻事件反讽式的解读,重新建立历史与个人的关联,自由、公正等一系列“大词”,以及在“90年代”的范畴里被视为妨害“日常生活”的政治言说,在韩寒的杂文中被再次激活。
对于“80后”一代,韩寒的写作提醒了一点,个人的体验与命运,终究和具体的历史情境相关——而这是郭敬明高度抽象化的写作所努力抹去的。
③韩寒提供了一种新的“形式”来回应作为“内容”的当下中国。
“80后”是在“80年代”历史终结后开始写作的。
韩寒式的“大时代”写作,是“大时代”终结之后的“大时代”写作,以往回应“大时代”的艺术形式,比如充满悲剧意味的“呐喊”,已然被历史所摧毁,我们所面对的不过是伟大的遗骸。
韩寒有意或无意地体悟到这一点,“大时代”终结之后的“大时代”写作,是一场文化游击战,不再是“子夜”时分的“呐喊”,而是历史尽头的“故事新编”,在囚笼高中语文第1页共8页般的历史内部——这是王小波作品中的核心意象——的戏仿、消解与颠覆。

2011年上海市虹口区高三一模语文试卷(附答案)
2011虹口区高三语文第一学期期末质量抽查试卷(满分:150分考试时间:150分)一、80分(一)阅读下文,完成1-6题。
(16分)①最近《人民日报》头版头条用了个新闻标题《江苏给力“文化强省”》,其中的“给力”二字新鲜独特,让很多人感到意外,迅速成为网络热词并引起争议。
②这让我联想到日前公布的《中国语言生活绿皮书暨中国语言生活状况报告》。
这份报告中收录了诸多有代表性的热字、热词和热语,即流行语。
有些人对此颇有微词,认为这些流行语所代表的语言现象不过是一时的时髦会破坏语言的“纯洁”和“规范”。
这种失之狭隘的观点反复申说了好多年——年年有流行语新冒出来,年年就有人老生常谈。
其实语言像一面镜子,如实地反映着社会生活和社会文化的变化,而在语言三要素中,又以词汇对上述变化的反映最为迅速、最为活跃。
因此,流行语蕴含着超乎语言本身的意义,值得关注也值得研究。
③流行语记录着社会变化。
早在上世纪60年代,美国有社会语言学家提出了著名的“语言与社会共变”理论,指出:语言对社会有依附性,即语言作为一种特殊的社会现象,随着会的发展而发展,因社会的变化而变化。
比如1977到1980年间我国集中出现的流行语“拨乱反正”、“党纪国法”、“平反”、“冤假错案”等等,就如实反映了这一时期的社会特征;之后经济改革启动,“市场调节”、“关停并转”、“个体户”、“中外合资”等一系列流行语又扑面而来。
流行语对社会变化感知的敏锐度与应变力是极为突出的。
④一些流行语具有丰富的含义。
有时,人们时同一流行语的解读,会因立足点不同而产生分歧,甚至理解截然相反,这并不会削弱它,反而能增加这些词语的张力,比如山寨”一词,最初源于香港,专指一些不正规的产品,是“不正宗”、“不正统”的意思,最入公众视线的“山寨”是“山寨手机”,之后出现了“山寨建筑”、“山寨春晚”等系列衍生品,人们也渐渐把“山寨”等同于“盗版”和“侵权”,但同时有人解释“山寨”为一种奢侈品趋向的妥协,是追慕的表现形式,还有人认为“山寨”闪耀着草根阶层的智慧——众多对“山寨”的解读,使得这个词的意义在使用中丰富起来,“山寨文化”,“山寨现象”甚至成了颇有深度的理论研究命题。

(16分)鲁迅:反抗者的精神文本林贤治①鲁迅自己说过,他的文字有两类,一类是为别人乃至为敌人的,一类是为自己的。
依照这种说法,小说当介于两者之间,既有的方面,也有的方面。
说到小说创作,他说:“我仍抱着十多年前的‘启蒙主义’,以为必须是‘为人生’,而且是要改良这人生。
”正是人生,把别人和自己统一到他的小说里来了。
②因为志在启蒙,作为小说家,鲁迅一开始就教他的读者把世界当作问题来理解,也就是说他必须把一个充满疑问的现实世界揭示出来。
这是一个吃人的世界:吃与被吃,各种各样的吃。
鲁迅把世界截然分为上下两大层面,在小说中,虽然也着意暴露上流社会的堕落,却更多地倾注了内心的悲悯,描述底层的不幸、那许许多多人们的被吃的情形,有学者统计说,《呐喊》、《》计二十五个短篇中,便有十三篇描写了二十四个人的“狂”与“死”。
死亡家庭成员有四种人:革命者或先觉者,知识分子,普通人,还有儿童。
统括起来,都是社会的无权者和弱势者。
夏济安对鲁迅小说里的黑暗面有特别深的认识,他指出:“鲁迅是一个善于描写死的丑恶的能手,不仅散文诗,小说也如此,他的小说中很多生动的形象都有着那样一种苍白的色调、呆滞的目光、缓慢而静悄悄的动作,以致在死亡完全抓攫他们以前,他们就已经有点像死尸了。
丧仪、坟墓、死刑,特别是杀头,还有病痛,这些题目都吸引着他的创造性的想象,在他的作品中反复出现,多种形式的死亡的阴影爬满了他的著作。
”一个恐怖的、悲惨的、荒谬的世界何以能够长存?对于有着五千年文明史的中国国民来说,这是一个问题,对此,鲁迅的小说并没有给出答案,其实当时作者本人未必便有答案,惟是留下艰难摸索的印迹,作为暗示读者的记号而已。

我夜晚从湖上归来,(杀鹅的)屠户门前有很多只鹅都在号叫,声音充满了大街小巷,好像在诉说着什么。
鹅很警觉,能够防盗,也能赶退蛇,它的粪便(能够)杀蛇。

But back then he was the one always made fun of in school gym classes in Devonshire, England.It was a mountain bike he received for his 15th birthday that changed him. At first he went biking alone in a nearby forest. Then he began to ride the bike along with a runner friend. Gradually, Saunders set up his mind on building up his body, increasing his speed and strength. At the age of 18, he ran his first marathon.The following year he met John Ridgway and started to work as an instructor at Ridgway’s school of adventure(冒险)in Scotland, where he learnt about Ridgway’s cold-water exploits. Greatly interested, Saunders read all he could about North Pole explorers and adventures, he decided that this would be his future.In 2001, after becoming a skillful skier, Saunders started his first long-distance expedition (探险)towards the North Pole. It took unbelievable energy. He suffered frostbite(冻伤), ran into a polar bear and pushed his body to the limit, pulling his sled up and over the rocky mountains.Saunders has since become the youngest person to ski alone to the North Pole, and he’s skied more of the North Pole by himself than any other British man.

There are hundreds of skills to help you read more in lesstime. Here are two skills that I think are especially good.Preview—if it’s long and hard. Previewing isespecially useful for getting a general idea of heavy reading like long magazine articles and business reports.Here’s how to preview.Read the first two paragraphs and the last two paragraphs carefully.Then read only the first sentence of the other paragraphs.Previewing doesn’t give you all the details. It keeps you from spending time on things you don’t really want -or need -or read.Skim-if it’s short and simple. Skimming is a goodway to get a general idea of light reading like popularmagazines or the sports and entertainment of your daily paper.Here’s how to skim.Get your eyes to move fast. Sweep them across eachline.Pick up only a few key words in each line.Everybody skims differently. You and I may not pick up the same words when we skim the same piece, but we’ll get a similar idea of what it’s all about.48. How many skills does the writer introduce to help us in reading?A. One.B. Two.C. Three.D. Four.49. What should you do if you read a long article according to the writer?A. Read every word of it.B. Read all the details.C. Pick up a few key words in each line.D. Read the first and the last two paragraphs carefully.50. If you read a simple article, which reading skill is better to get the general idea?A. Previewing.B. Skimming.C. Reading.D. Sweeping.B“Teenager”means a person from 13 to 19 yearsold. Although they’re young, they have to make manyimportant choices by themselves. Often teachers andparents cannot handle them because they don’tunderstand and know teenagers, especially their wishes,problems or different moods in a short time. They needto think about questions like these: Should we go tocollege? What kind of job do I want? However, otherpeople also influence their choices. Who influences teenagers?It depends on the kind of choice. When teenagers buy things, friends are the most important influence. This is especially true for clothes and music. TV shows, advertisements and parents also influence teenagers. In more serious things, parents are probably the most important influence. Some teenagers say it’s best to regard both parents and friends as influences. James, a seventeen-year-old boy says he’s―just a crazy man ‖. He also says, ―Parents are really important because they can tell you what ’s right and wrong.‖But teenagers also feel they need to make choices —to make their own mistakes. As one teenager girl said, ―If our parents don ’t let us make our own choices, maybe in the future we don ’t know how to do it.‖ And they feel friends can often be a big help, especially because friends sometimes know more about their situation than their parents.51. Why do teenagers sometimes have to make their own choices?A. Because the teachers want them to do it.B. Because their parents want them to do it.C. Because teenagers like to make choices by themselves.D. Because teachers and parents don ’t understand them well.52. Who influences most to the teenagers when they buy music?A. Their teachers.B. Theirs parents.C. Their friends.D. Movie stars.53. What does the passage mainly talk about?A. Everybody needs to make choices.B. Teenagers need to make choices by themselves.C.

There are two reasons —land and wood. In many countries the trees have been cut down because the land was needed for animals or crops. In other parts of the world the trees are cut down because their wood is wanted. This wood is used by local people for firewood or it is used for building. But many people don’t know that in most places the trees won’t be replaced. The soil in the forests is very thin, but it is protected by the trees. When the trees are cut down, the soil is washed away by the rain or blown away by the wind. Soon nothing can be grown on it. The forest becomes a desert. Then more land will be needed, and more trees will be cut down.When the forest is destroyed, it isn’t only the trees that are lost —the homes of millions of animals and plants are destroyed, too. All kinds of animals are in danger —fish,reptiles, birds, mammals, insects, and shellfish —as well as thousands of plants.Who is to blame for this? The answer is simple: all of us. There are just too many people in the world. The world’s population is now six billion. Of course, it’s very easy to blame the local people. We don’t cut down trees. They do. But the products are bought by people like you and me —wood houses, beds, tables, chairs, paper…Why are the forests being destroyed? Just look around. You are probably using it right now.51.

Nowadays games on the net are very popular with college students. Some of my roommates are very interested in them. They not only play games in their free time, but also keep talking about them at night when lights are off, and they regard games as a part of their life. I’ve asked them to give it up, but they wouldn’t listen to me. It has become a rather big problem. Should I report it to our teachers or do something else?TedDear Ted,Drop it. Your roommates, as grown—ups, can do whatever they want with their time so long as it doesn’t break school rules or violate(妨碍)other people’s interests.Playing perhaps gives these students relaxation from hard study. If they play too often and have little time to study, they will reap what they have sown(自食其果), but you will not. Reporting to the teachers would only harm your good name in your dormitory(宿舍). However, you have rights to ask your roommates to be quiet when you need sleep. If they aren’t angry with you, they will stop talking. But be polite and friendly. Perhaps, in return, join them in a game or two.Victor51.
