(6分)①因为马克思首先是一个革命家。

他毕生的真正使命,就是以这种或那种方式参加推翻资本主义社会及其所建立的国家制度的事业,参加现代无产阶级的解放事业。

正是他第一次使现代无产阶级意识到自身的地位和需要,意识到自身解放的条件。

斗争是他的生命要素。

而他进行斗争的热烈、顽强和卓有成效,是很少见的。

最早的《莱茵报》(1842年),巴黎的《前进报》(1844年),《德意志-布鲁塞尔报》(1847年),《新莱茵报》(1848-1849年),《纽约每日论坛报》(1852-1861年),以及许多富有战斗性的小册子,在巴黎、布鲁塞尔和伦敦各组织中的工作,最后,作为全部活动的顶峰,创立伟大的国际工人协会,——老实说,协会的这位创始人即使别的什么也没有做,也可以为这一成果自豪。

②正因为这样,所以马克思是当代最遭嫉恨和最受诬蔑的人。

各国政府——无论专制政府或共和政府,都驱逐他;资产者——无论保守派或极端民主派,都竞相诽谤他,诅咒他。

他对这一切毫不在意,把它们当作蛛丝一样轻轻抹去,只是在万分必要时才给予答复。

现在他逝世了,在整个欧洲和美洲,从西伯利亚矿井到加利福尼亚,千百万革命战友无不对他表示悼念、爱戴和尊敬,而我敢大胆地说:他可能有过许多敌人,但未必有一个私敌。

③他的英名和事业将永垂不朽!1.下列加点字写法或注音有误..的一项是()。

(1分)A.顶峰.(fēng) B.嫉.恨(jì) C.诽.谤(fěi) D.不朽.(xiǔ)2. 第②段画线句存在语病,请加以修改。

(2分)3.第①段运用了什么论证方法?有何作用?(3分)(二)、阅读下文,完成4——7题。

(10分)①多媒体音乐会,这种听起来高科技现代化的音乐会产品,如今出现得越来越频繁。

前几天的“肖邦〃爱”多媒体浪漫钢琴音乐剧便是一大代表。

差不多半个世纪后,同样是法国人的勒庞发现,大众的理性能力非常值得怀疑。

又过了半个世纪,在1930年代,西班牙哲学家加塞特发现了“大众灾难”的秘密——纳粹德国不过是大众集体非理性的合乎逻辑的结果。

①“大众”这一概念,隐含着是“现代社会”的产物。

而我们说到以宏大叙事、激昂理想为特征的“大时代”和以个体、群体的小情趣、小偏好为特征的“小时代”,恰恰和“大众”、“现代社会”这两个概念息息相关——它们都是公共领域裂变①的结果。

②从英国工业革命时算起,包括以上的时间片段,无疑都是西方在现代化进程中的“大时代”:政治、经济、社会、文化命题宏大、高远,其间,伴随着残酷的战争。

在时代议题中,个人和小群体的趣味偏好无容身之地。

西方的现代化历程、中国从1911年到20世纪80年代的历程已经说明了这一点。

一个“大时代”,无人可以抗拒。

因为不跟随、参与、介入,个人将找不到意义,将有被抛弃感。

在“大时代”可以找到的自我面前,“小时代”的那种渺小的自我几乎不堪一击。

比如,20世纪30年代,在革命面前,一些具有“小资产阶级”情调的富家子弟,一些学生,就会感到个人的那些小情调是多么可笑。

革命所对应的“大时代”,使他们没有任何犹豫地迅速埋掉他们过去的自我。

然而按照勒庞、弗洛伊德、加塞特等人的说法,大众身上燃烧着的那些非理性的激情,极容易成为玩宏大叙事、政治修辞的领袖人物改变政治结构的能量。

毫无疑问,在这样的大众眼中,个人趣味、偏好渺小得不值一提。

The authors — at the Safra Center for Brain Science at Hebrew University in Israel — put people who had been blind since birth through 70 hours of training with a visual-to-auditory sensory (感官的) substitution 42 .Initially, the subjects were able to 43 among faces, houses, everyday objects, and body shapes. They were able to read letters and words, identify facial expressions and locate people’s positions 44 . In one video, a blind person is shown a picture of a woman with a ponytail and identified the hairstyle.Blind people have long used the capability to use another sensory ability to make up for blindness: Braille and blind walking canes allow people without sight to read and navigate. But when the authors of the current study put subjects in a brain scanner, they 45 insight into the process by which training with a sensory substitution device allowed the mind’s eye to “see”.The human brain is a 46 efficient and adaptable organ: when a sensory perception such as sight is lost, the specialized regions of the brain in which input from the eyes is processed are 47 to other duties.But scientists have long believed that the brain’s 48 is limited by early conditions: when a person is born blind, the capacity of the brain’s visual cortex (大脑皮层) to process sight never develops, scientists have believed. With that 49 opportunity, a window is closed, and even if eyesight were to be restored, the visual cortex, they believed, would forever remain “blind” to images.III.

NeverthelessA. contemporaryB. similarC. differentD. initialA. realizeB. attachC. demonstrateD. weakenA. unlikelyB. sensibleC. jealousD. miserableSection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)I believe that memory is never lost, even when it seems to be, because it has more to do with the heart than the mind.At the same time my 44-year-old husband, Ed, was losing his life, my mother was losing her ability to remember. She forgot how to start the car, whether or not she had eaten and which family members had died — including my father.I became afraid that one day I, too, would be unable to recall my husband, not because of Alzh eimer’s (早老性痴呆), but simply because my memory of him might disappear. So from the day of Ed’s diagnosis (诊断) until his death a year later, I set out to memorize him. I’d always be able to recite his qualities — kind, gentle, smart, funny — but I wanted to be able to think about the physical man in my mind as fully as possible when he was gone.Later I learnt that memory has a will of its own. You can’t control it any more than you can influence the weather. When it springs up, a person loved and lost is found, even just for a few seconds.Recently, when I was driving, I had a deep and sudden sense of Ed, and the way it felt to have him next to me in the car. My body softened as it used to when we were together seven years ago, living a shared life. I wasn’t remembering his face or the way he walked; the careful details I had stored had nothing to do with this moment in the car. And my mom’s brain couldn’tlabel my father correctly, but that was not important. It was clear to me that her husband was vivid in her heart, a memory even Alzheimer’s could not destroy.I believe there is a difference between memory and remembering. Remembering has something to do with turning the oven off before leaving the house, but memory is nurtured by emotion. It springs from a deeper well, safe from the passage of time.Ed is _____.A. the author’s mother B. the author’s fatherC. the author’s husband D. a physical manMemory has its own will so _____.A. the weather can’t control our memory B. it may happen anytime and anywhereC. it can spring up for a few seconds D. it is safe from a passage of timeWhich of the following statements is TRUE according to the passage?A. Alzeimer’s is not very harmful to human beings.B. A physical man must be kind, gentle, smart, funny.C. Mem ory has much to do with the deep emotion in one’s heart.D. Good memory begins with turning the oven off before leaving.What is the best title of the passage?A. Memory —the deeper well from our heartB. Differences between memory and rememberingC. Alzheim er’s can never destroy our memoryD. Memory — the passage of timeThe letter is probably from _____.A. Supervisor Management Unit B. Thames Valley PoliceC. Criminal Justice System D. Crime Reduction CommitteeMs. Adamczak is _____.A. a victim in a crime B. a famous crime-news reporterC. a professional policeman D. a detective in clearing up crimesWhat does the word “leads” most probably mean?A. Clue.B. Darkness. C. Investigation. D. Contact.(C)The infant who begins to smile or laugh early will _____.A. have more advantages of development in growth and healthB. suffer from schizophrenic psychosis and even die in later lifeC. become a more subtle laughter when he or she grows upD. be more likely to take a whole life to perfect smiling and laughingThe expression “the first” in Paragraph 2 refers to _____.A. a leading factor B. recalling evening activitiesC. mastery over anxieties D. learning to laughWhich of the following statements can be inferred from the passage?A. The more you laugh and smile, the more likely you will be to succeed.B. Smile and laugh show your ability to overpower weakness and anxieties.C. Mastering social relationships means having a sense of humor.D. Scientists are more likely to go into laughing with no apparent reason.What is the best title of the passage?A. Beyond Laughter — A new book with fruitful findingsB. Smiling — A new mastery over anxietiesC. An important sign of confidence and successD. The function and meanings of smilingSection CDirections: Read the following text and choose the most suitable heading from the list A-F for each paragraph. There is one extra heading which you do not need.Is it ever too late to make changes?What’s one change you’d most like to see in your patients?What do you think your patients know about heart health surgery?Can you talk about some surprising risk factors for heart disease?Can you list the ill effects of smoking among common people?What are the biggest mistakes that people make about their heart health?77.We have a whole list of what we describe as “emerging” risk factors. Scientific evidence links them to the development of heart disease, although the strength of the evidence is not as solid as the evidence for the links between heart disease and high blood pressure or smoking.78.Not all doctors and hospitals are the same. Your health is too important not to do some research. Most people spend more time researching a new car than they do a heart surgeon. Ask questions. Get second opinions. Make sure that you get the best for your health. And don’t be worried about offending a doctor by going elsewhere for a second opinion. All of these are what you should be clear about.79.Too many patients wrongly believe in the claims for diets and dietary supplements. We have had many patients stop treatments because they have been convinced that a particular diet will reverse their heart disease. Improving heart health by taking dietary supplements is a totally national rumor.80.Exercise. Too many pat ients stay at home and sit before computer desks. We’d like to see everybody make the time to exercise for 30 minutes a day. It’s simple. Find a friend and go for a walk. You can even split it up into 10- or 15-minute increments. Maybe, it’s a new begin fo r some patients.Section DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)The purpose of Berland and Schoen’s research is to __________.What is the leading factor that helps individuals to be successful according to Berland and Schoen?How will a Natural-Born Leader feel when he is told to finish some challenging tasks?Berland and Schoen have studied Independent Seekers in the two aspects: __________.第II卷(共45分)I.

Each word can only be used once. Note that there is one word more than you need.People blind from birth can be taught to “see” images that are conveyed as sounds, says a new study that calls into question a 41 belief about the limits of the human brain.Devices that scan visual images and re-interpret regularities as sounds were used to re-train the brains of born-blind people in a study published this week inthe journal Neuron. The authors — at the Safra Center for Brain Science at Hebrew University in Israel — put people who had been blind since birth through 70 hours of training with a visual-to-auditory sensory (感官的) substitution 42 .Initially, the subjects were able to 43 among faces, houses, everyday objects, and body shapes. They were able to read letters and words, identify facial expressions and locate people’s positions 44 . In one video, a blind person is shown a picture of a woman with a ponytail and identified the hairstyle.Blind people have long used the capability to use another sensory ability to make up for blindness: Braille and blind walking canes allow people without sight to read and navigate. But when the authors of the current study put subjects in a brain scanner, they 45 insight into the process by which training with a sensory substitu tion device allowed the mind’s eye to “see”.The human brain is a 46 efficient and adaptable organ: when a sensory perception such as sight is lost, the specialized regions of the brain in which input from the eyes is processed are 47 to other duties.But scientists have long believed that the brain’s 48 is limited by early conditions: when a person is born blind, the capacity of the brain’s visual cortex (大脑皮层) to process sight never develops, scientists have believed. With that 49 opportunity, a window is closed, and even if eyesight were to be restored, the visual cortex, they believed, would forever remain “blind” to images.III.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices markedA, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)I believe that memory is never lost, even when it seems to be, because it has more to do with the heart than the mind.At the same time my 44-year-old husband, Ed, was losing his life, my mother was losing her ability to remember. She forgot how to start the car, whether or not she had eaten and which family members had died — including my father.I became afraid that one day I, too, would be unable to recall my husband, not because of Alzheimer’s (早老性痴呆), but simply because my memory of him might disappear. So from the day of Ed’s diagnosis (诊断) until his death a year later, I set out to memorize him. I’d always be able to recite his qualities —kind, gentle, smart, funny — but I wanted to be able to think about the physical man in my mind as fully as possible when he was gone.Later I learnt that memory has a will of its own. You can’t control it any more than you can influence the weather. When it springs up, a person loved and lost is found, even just for a few seconds.Recently, when I was driving, I had a deep and sudden sense of Ed, and the way it felt to have him next to me in the car. My body softened as it used to when we were together seven years ago, living a shared life. I wasn’t remembering his face or the way he walked; the careful details I had stored had nothing to do with this moment in the car. And my mom’s brain couldn’t label my father correctly, but that was not important. It was clear to me that her husband was vivid in her heart, a memory even Alzheimer’s could not destroy.I believe there is a difference between memory and remembering. Remembering has something to do with turning the oven off before leaving the house, but memory is nurtured by emotion. It springs from a deeper well, safe from the passage of time.65.Ed is _____.A. the author’s motherB. the author’sfatherC. the author’s husban dD. a physicalman66.Memory has its own will so _____.A. the weather can’t control our memoryB. it may happenanytime and anywhereC. it can spring up for a few secondsD. it is safe from a passage of time67.Which of the following statements is TRUE according to the passage?A. Alzeimer’s is not very harmful to human beings.B. A physical man must be kind, gentle, smart, funny.C. Memory has much to do with the deep emotion in one’s heart.D. Good memory begins with turning the oven off before leaving.68.What is the best title of the passage?A. Memory — the deeper well from our heartB. Differences between memory and rememberingC. Alzheimer’s can never destroy our memoryD. Memory — the passage of time69.The letter is probably from _____.A. Supervisor Management UnitB. Thames Valley PoliceC. Criminal Justice SystemD. Crime Reduction Committee70.Ms. Adamczak is _____.A. a victim in a crimeB. a famouscrime-news reporterC. a professional policemanD. a detective in clearing up crimes71.What does the w ord “leads” most probably mean?A. Clue.B. Darkness.C. Investigation.D. Contact.(C)72.The infant who begins to smile or laugh early will _____.A. have more advantages of development in growth and healthB. suffer from schizophrenic psychosis and even die in later lifeC. become a more subtle laughter when he or she grows upD. be more likely to take a whole life to perfect smiling and laughing73.The expression “the first” in Paragraph 2 refers to _____.A. a leading factorB. recalling evening activitiesC. mastery over anxietiesD. learning to laugh74.Which of the following statements can be inferred from the passage?A. The more you laugh and smile, the more likely you will be to succeed.B. Smile and laugh show your ability to overpower weakness and anxieties.C. Mastering social relationships means having a sense of humor.D. Scientists are more likely to go into laughing with no apparent reason.75.What is the best title of the passage?A. Beyond Laughter— A new book with fruitful findingsB. Smiling — A new mastery over anxietiesC. An important sign of confidence and successD. The function and meanings of smilingSection CDirections: Read the following text and choose the most suitable heading from the list A-F for each paragraph. There is one extra heading which you do not need.A.Is it ever too late to make changes?B.What’s one change you’d most like to see in your patients?C.What do you think your patients know about heart health surgery?D.Can you talk about some surprising risk factors for heart disease?E.Can you list the ill effects of smoking among common people?F.What are the biggest mistakes that people make about their hearthealth?77.We have a whole list of what we describe as “emerging” risk factors. Scientific evidence links them to the development of heart disease, although the strength of the evidence is not as solid as the evidence for the links between heart disease and high blood pressure or smoking.78.Not all doctors and hospitals are the same. Your health is too important not to do some research. Most people spend more time researching a new car than they do a heart surgeon. Ask questions. Get second opinions. Make sure that you get the best for your health. And don’t be worried about offending a doctor by going elsewhere for a second opinion. All of these are what you should be clear about.79.Too many patients wrongly believe in the claims for diets and dietary supplements. We have had many patients stop treatments because they have been convinced that a particular diet will reverse their heart disease. Improving heart health by taking dietary supplements is a totally national rumor.80.Exercise. Too many patients stay at home and sit before computer desks. We’d like to see everybody make the time to exercise for 30 minutes a day. It’s simple. Find a friend and go for a walk. You can even split it up into 10- or 15-minute increments. Maybe, it’s a new begin for some patients.Section DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.(Note:Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)81.The purpose of Berland and Schoen’s research is to __________.82.What is the leading factor that helps individuals to be successful accordingto Berland and Schoen?83.How will a Natural-Born Leader feel when he is told to finish some challengingtasks?84.Berland and Schoen have studied Independent Seekers in the two aspects:__________.第II卷(共45分)I.

阅读(80分)一、阅读下面的文章,完成1-6题。

(17分)①先秦诸子由于社会影响巨大,历史贡献卓著,因此对中国文脉的形成有特殊贡献。

我把先秦诸子的文学品相分为三个等级――第一等级:庄子、孟子;第二等级:老子、孔子;第三等级:韩非子、墨子。

在这三个等级中,处于第一等级的庄子和孟子已经是文学家,而庄子则是一位大文学家。

②把老子和孔子放在第二等级,实在有点委屈这两位精神巨匠了。

我想他们本人都无心于自身的文学建树,但是,虽无心却有大建树。

这便是天才,这便是伟大。

在文脉上,老子和孔子谁应领先?这个排列有点难。

相比之下,孔子的声音,是恂恂教言,浑厚恳切,有人间炊烟气,令听者感动,令读者萦怀;相比之下,老子的声音,是铿锵断语,刀切斧劈,又如上天颁下律令,使听者惊悚,使读者铭记。

孔子开创了中国语录式的散文体裁,使散文成为一种有可能承载厚重责任、端庄思维的文体。

孔子的厚重和端庄并不堵眼堵心,而是仍然保持着一个健康君子的斯文潇洒。

更重要的是,由于他的思想后来成了千年正统,因此他的文风也就成了永久的楷模。

他的文风给予中国历史的,是一种朴实的正气,这就直接成了中国文脉的一种基调。

中国文脉,蜿蜒曲折,支流繁多,但是那种朴实的正气却颠扑不灭。

因此,孔子于文,功劳赫赫。

本来,孔子有太多的理由在文学上站在老子面前,谁知老子另辟奇境,别创独例。

以极少之语,蕴极深之义,使每个汉字重似千钧,不容外借。

在老子面前,语言已成为无可辩驳的天道,甚至无须任何解释、过渡、调和、沟通。

这让中国语文,进入了一个几乎空前绝后的圣哲高台。

我听不止一位西方哲学家说:"[甲]从语言方式,老子[乙]是最高哲学。

孔子不如老子果断,因此在外人看来,更像一个教育家、社会评论家。

"外国人即使不懂中文,也能从译文感知"最高哲学"的所在。

有一段时间,德国人曾骄傲地说:"全世界的哲学都是用德文写的。

"这当然是故意的自我夸耀,但平心而论,回顾以前几百年,德国人也确实有说这种"大话"的底气。

然而,当他们读到老子就开始不说这种话了。

据统计,现在几乎每个德国家庭都有一本老子的书,其普及度远远超过老子的祖国。

③说完第二等级,我顺便说一下第三等级。

韩非子和墨子,都不在乎文学,有时甚至明确排斥。

但是,他们的论述也具有了文学素质,主要是那些干净而雄辩的逻辑所造成的简洁明快,让人产生了一种阅读上的愉悦。

当然,他们两人实干家的形象,也会帮助我们产生文字之外的动人想象。

④更重要的是要让出时间来看看第一等级,庄子和孟子。

孟子是孔子的继承者,比孔子晚了一百八十年。

在人生格调上,他与孔子很不一样,显得有点骄傲自恃,甚至盛气凌人。

这在人际关系上好像是缺点,但在文学上就不一样了。

他的文辞,大气磅礴,浪卷潮涌,畅然无遮,情感浓烈,具有难以阻挡的感染力。

他让中国语文,摆脱了左顾右盼的过度礼让,连接成一种马奔车驰的畅朗通道。

文脉到他,气血健旺,精神抖擞,注入了一种"大丈夫"的生命格调。

⑤但是,与他同一时期,一个几乎与他同年的庄子出现了。

庄子从社会底层审察万物,把什么都看穿了,既看穿了礼法制度,也看穿了试图改革的宏谋远虑,因此对孟子这样的浩荡语气也投之以怀疑。

岂止对孟子,他对人生都很怀疑。

真假的区分在何处?生死的界线在哪里?他陷入了困惑,又继之以嘲讽。

这就使他从礼义辩论中撤退,回到对生存意义的探寻,成了一个由思想家到文学家的大步跃升。

⑥他的人生调子,远远低于孟子,甚至也低于孔子、墨子、荀子或其他别的"子"。

但是这种低,使他有了孩子般的目光,从世界和人生底部窥探,问出一串串最重要的"傻"问题。

但仅仅是这样,他还未必能成为先秦诸子中的文学冠军。

他最杰出之处,是用极富想象力的寓言,讲述了一个又一个令人难忘的故事,而在这些寓言故事中,都有一系列鲜明的艺术形象。

这一下,他就成了那个思想巨人时代的异类、一个充满哲思的文学家。

他的文章,就成了中国哲学史、也是中国文学史的第一流佳作。

⑦此后历史上一切有文学才华的学人,都不会不粘上庄子。

这个现象很奇怪,对于其他"子",都因为思想观念的差异而有明显的取舍,但庄子却例外。

没有人会不喜欢他讲的那些寓言故事,没有人会不喜欢他与南天北海融为一体的自由精神,没有人会不喜欢他时而巨鸟、时而大鱼、时而飞蝶的想象空间。

⑧在这个意义上,形象大于思维,文学大于哲学,活泼大于庄严。

1.文章第一段中提到的先秦诸子分属儒家、道家、___家和___家。

(2分)2.第二段中“委屈”一词在本文中的意思是____。

(2分)3.联系上下文,为第二段的画线句选项填空,并简述理由。

(3分)选项一:仅就是;选项二:如果是4.在文章前半部分,作者用大量的笔墨写孔子和老子,请分析这样构思的用意。

(3分)5.下面不符合文意的一项是()(2分)A.在文脉上老子和孔子文章各有千秋,是两种不同的风格,难分伯仲。

B.中国文脉绵延至今,虽然支流繁多,但其基调始终是一种朴实的正气。

C.孟子的精神气质与其文章相辅相成,为中国文脉注入了一种“大丈夫”的生命格调。

D.庄子的文章因为深邃的哲思和自由的精神,成为了中国哲学史和文学史上第一流的佳作。

6.概括作者对先秦诸子“文学品相”分级的标准,并简要阐述你对此标准的看法。

(5分)二、阅读下面的文章,完成7-13题。

(21分)市集沈从文①廉纤的毛毛细雨,在天气还没有大变以前欲雪未能的时节,还是霏霏微微落将下来。

一个小小乡场,位置在又高又大陡斜的山脚下,前面濒着瘦瘦的河,被如烟如雾雨丝织成的帘幕,一起把它蒙罩着了。

②照例的三八市集,还是照例的有好多好多乡下人,小田主,买鸡到城里去卖的小贩子,花幞头大耳环丰姿隽逸的苗姑娘,以及一些穿灰色号褂子的副爷们、穿高筒子老牛皮靴的团总……各从附近的乡村来做买卖。

他们的草鞋底半路上带了无数黄泥浆到集上来,又从场上大坪坝内带了不少的灰色浊泥归去。

去去来来,人也数不清多少。

③集上的骚动,吵吵闹闹,凡是到过南方(湖湘以西)乡下的人,是都会知道的。

倘若你是由远远的另一处地方听着,那种喧嚣的起伏,你会疑心到是滩水流动的声音了!这种洪壮的潮声,还只是一般做生意人在讨论价钱时很和平的每个论调而起。

就中虽也有遇到卖牛的场上几个人象唱戏黑花脸出台时那么大喊大嚷找经纪人,也有因秤上不公允而起口角——然而究竟还是因为人太多,一两桩事,实在是万万不能做到的!④卖猪的场上,他们把小猪崽的耳朵提起来给买主看时,那种尖锐的嘶喊声,使人听来不愉快至于牙齿根也发酸。

卖羊的场上,许多美丽驯服的小羊儿咩咩地喊着。

一些不大守规矩的大羊,无聊似的,两个把前蹄举起来,作势用前额相碰。

大概相碰是可以驱逐无聊的,所以第一次訇的碰后,却又作势立起来为第二次预备。

牛场却单独占据在场左边一个大坪坝,因为牛的生意在这里占了全部交易四分一以上。

那里四面搭起无数小茅棚(棚内卖酒卖面),为一些成交后的田主们喝茶喝酒的地方。

那里有大锅大锅煮得“稀糊之烂”的牛脏类下酒物,有大锅大锅香喷喷的肥狗肉,有从总兵营一带担来卖的高粱烧酒;也还有城里馆子特意来卖面的。

假若你是城里人来这里卖面,他们因为想吃香酱油的缘故,都会来你馆子,那么,你生意便比其他铺子要更热闹了。

⑤到城里时,我们所见到的东西,不过小摊子上每样有一点罢了!这里可就大不相同。

单单是卖鸡蛋的地方,一排一排地摆列着,满箩满筐的装着,你数过去,总是几十担。

辣子呢,都是一屋一屋搁着。

此外干了的黄色草烟,用为染坊染布的五倍子和栎木皮,还未榨出油来的桐茶子,米场白濛白濛了的米,屠桌上大只大只失了脑袋刮得净白的肥猪,大腿大腿红腻腻还在跳动的牛肉……都多得怕人。

不大宽的河下,满泊着载人载物的灰色黄色小艇,一排排挤挤挨挨的相互靠着也难于数清。

⑥市集中是没有什么统系制度。

虽然在先前开场时,总也有几个地方上的乡约伯伯,团总,守汛的把总老爷,口头立了一个规约,卖物的照着生意大小缴纳千分之几——或至万分之几,但也有百分之几——的场捐,或经纪佣钱,棚捐,不过,假若你这生意并不大,又不须经纪人,则不须受场上的拘束,可以自由贸易了。

⑦到这天,做经纪的真不容易!米场脚底下笼着他那双厚底高筒的老牛皮靴子,为这个爬斗;为那个倒箩筐。

牛羊场的一面为这个那个拉拢生意,身上让卖主拉一把,又让买主拉一把;一面又要顾全到别的地方因争持时闹出岔子的调排,委实不是好玩的事啊!大概他们声音都略略嚷得有点嘶哑,虽然时时为别人扯到馆子里去润喉。

不过,他今天的收入,也就很可以酬他的劳苦了。

⑧因为阴雨,又因为做生意的人各都是在各自村子里住家,有些还得在散场后走到二三十里路的别个乡村去;有些专靠漂场生意讨吃的还待赶到明天那个场上的生意……所以散场很早。

不到晚炊起时,场上大坪坝似乎又觉得宽大空阔起来了!……再过些时候,除了屠桌下几只大狗在啃嚼残余,因分配不平均在那里不顾命的奋斗外,便只有由河下送来的几声清脆篙声了。

⑨归去的人们,间或有骑着马,马项颈下挂着一串小铜铃叮叮当当跑着的,但这是少数;大多数还是赖着两只脚在泥浆里翻来翻去。

他们总笑嘻嘻的担着箩筐或背一个大竹背笼,满装上青菜、萝卜、牛肺、牛肝、牛肉、盐、豆腐、猪肠子一类东西。

手上提的小竹筒不消说是酒与油。

有的拿草绳套着小猪小羊的颈项牵起忙跑;有的肩膊上挂了一个毛蓝布绣有白四季花或“福”字“万”字的褡裢,赶着他新买的牛;有的却是口袋满装着钱心中满装着欢喜,——这之间各样人都有。

7.文章开头的环境描写的作用是____。

(2分)8.文章第二、三两段写出了“三八市集”_________的特点。

(2分)9.关于文章的第四段,下列说法正确的一项是:()(2分)A.这段的内容由市集中的人转向市集中的货品,在结构上有承上启下的作用。

B.作者用拟人的手法写大羊相斗来“驱逐无聊”,目的是反映市集中牲畜交易的萧条。

C.那么卖酒卖面的小茅棚是到集市中做交易的人们喝茶喝酒和谈生意的地方。

D.作者选择的场景从牲畜交易的场所到卖酒卖面的茅棚,文字不多但画面丰富。

10.简析文章第五段中“一排一排”、“一屋一屋”、“白濛白蒙”等叠词的表达效果。

(3分)11.结合文章第七、八两段内容,简述动静结合的描写手法在本文中的作用。

(4分)12.对本文理解和赏析正确的两项是()()(4分)A.作者在第二段写到村民草鞋底上的泥,意在表现他们平日生活的劳累和艰辛。

B.在市集上做生意的人都必须按规矩缴纳一定数额的“场捐”、“棚捐”和“经纪佣钱”。
