D.Emergency First aid.CWith alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills (泄露)on people, nature, and the environment.Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil.Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea.Of all of today's environmental disasters, an oil spill may actually be one of the least serious.Although oil is poisonous, it is a natural material.In the end, it breaks down naturally.There are, of course, long-term effects, but it is usually more serious in the short term.Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible.In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tones of oil into the ocean.If you go there today, you will find it hard to see any sign that it ever happened.Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage.Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run IWe should be thinking more about reducing our dependency on oil.Governments should be encouraging research into new technologies, such as cars run by solar power (太阳能), electricity, hydrogen, and soon.Much of this research has, in the past, been held back by the oil, gas, and coal.If the world's millions of cars were 10% more efficient (高效的)—and the industry could easily produce cars at least twice as efficient ?we would need many fewer tankers crossing the oceans each year.If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.63.What is the passage mainly talking about?A.Oil spills pollution.B.What oil pollution is.C.Oil tanker accidents. D.How to reduce oil pollution. 64.How does the author support the idea that oil spills are not as serious as people believe?A.By giving a description.B.By making an argument.C.By giving an example.D.By drawing a diagram.65.What does the underlined word "risk" in Paragraph 5 refer to?A.Transportation depending more on oil.B.Poisonous oil breaking down naturally.C.Millions of tons of oil spilling into the sea.D.More environmental damage being caused.66.Which suggestion, is made for reducing oil tank accidents according to the passage?A.We should build safer tankers in the near future.B.We should develop new technologies to cut oil use.C.Tankers should not be allowed to sail near the coastlines.D.Countries should build more oil pipelines under the sea.DRecently there was a major discovery in the scientific research—the mapping of all DNA in a human gene (基因)is complete.Couple of years ago, this seems an impossible task for scientist to accomplish.All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away.Human cloning has always been a topic of argument, in terms of morality or religion.Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning.If the clone was free of genetic limitations.then the other clone would be as well.The latter could foe inserted in the woman and allowed to ripen to term.Moreover, cloning would enable women, who can't get pregnant, to have children of their own.Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs.This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more)organ (s).It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.Arguments against cloning are also on a perfectly practical side.Primarily, I believe that cloning would step in the normal "cycle" of life.There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development—the fundamental reason how living things naturally adapt to the ever-changing environment.Life processes failing to do so might result in untimely disappearance.Furthermore, cloning would make the uniqueness that each one of us possesses disappear.Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would beregarded as "objects" rather than people in the society.Scientists haven't 100 per cent.guaranteed that the first cloned humans will be normal.Thus this could result in introduction of additional limitations in the human "gene-pool".Regarding such arguable topics in "black or white" approach seems very innocent to me personally.We should rather try to look at all "shades" of it.I believe that cloning is only legal if its purpose is for cloning organs; not humans.Then we could regard this as for "saving life" instead of "creating life".I believe cloning humans is morally and socially unacceptable.67.Which of the following is true according to the passage?A.Genetic limitation will be beneficial for some women.B.A large number of genes will prevent us from developing.C.Prohibition of cloning might limit the freedom of scientists.D.First cloned humans might be normal according to scientists.68.What's the author's opinion on cloning?A.Cloning should be entirely banned.B.Cloning should be used in creating life.C.Cloning will take away the right to reproduce.D.Cloning is acceptable if it is used for cloning organs.69.Where can you read this article?A.In a story book.B.In a magazine.C.In a science fiction.D.In a brochure.70.Which of the following shows thestructure of the passage?第二节(共5小题;每小题2分,共10分)On a typical hot August day in Xianyou County, Fujian Province, Zeng Demei, a retired worker in his seventies, hurries down a busy street.In his hand is a black leather bag.Zeng opens his bag, taking out two forms.71 Each of the forms contains detailed information of a student.On his arrival two hours later a woman greets him and leads him to her office where another man is waiting.They are the two village officials.They inspect the forms handed to them by Zeng and immediately recognize the girls.72 ? "It’s a pity but it doesn't matter." says Zeng, who wastes no time in deciding to look for the remaining child, Su Qiuju.After half an hour, they stop outside a small house made of mud brick.A middle-aged man and a girl in a faded pink dress greet them.Su Qiuju is eight years old.She was forced to drop out of school after both her parents died.She is now living with her uncle who cannot afford his own children's education.However, the year of education Su Qiuju did complete was a successful one.73 .When they are about to leave, Zeng says, "I must find a supporter for this girl to sponsor her education." Zeng has made it his retirement task to help children complete their schooling.Back in 1999, Zeng took part in a campaign started by the local women's organization to help students from poor families.74 His task had begun and since then he has spent his time persuading his friends and neighbors and others to donate money."To me, children's education is the most important.75 I have to find sufficient funding before the school opens in September."When asked how long he will keep up his vital work as the community's guardian angel, he has a simple reply." Not until my eyes can't see, and my feet can't move."A.They were having problems with their schoolworkB.These are for the two girls he's going to visit this morningC.They live in a small village not very far, though only one of the girls is still living at homeD.She displayed a talent for handwriting, writing her three-character name neatly and beautifullyE.The thought of students dropping out of school bothers me so much that I can't get to sleep at nightF.Of course, some people question why I would want to give up my retirement to go to so much trouble G.He was so overcome by the tough situation of many poor children ?that he donated all his money to help out a girl第四部分:书面表达(共两节,35分)第一节:情景作文(20分)假设你是红星中学高三(1)班的班长李华,你们全班同学在“五一节”放假期间开展了“体验一天低碳生活”的活动。

D.Emergency First aid.CWith alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills (泄露)on people, nature, and the environment.Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil.Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea.Of all of today's environmental disasters, an oil spill may actually be one of the least serious.Although oil is poisonous, it is a natural material.In the end, it breaks down naturally.There are, of course, long-term effects, but it is usually more serious in the short term.Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible.In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tones of oil into the ocean.If you go there today, you will find it hard to see any sign that it ever happened.Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage.Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run IWe should be thinking more about reducing our dependency on oil.Governments should be encouraging research into new technologies, such as cars run by solar power (太阳能), electricity, hydrogen, and soon.Much of this research has, in the past, been held back by the oil, gas, and coal.If the world's millions of cars were 10% more efficient (高效的)—and the industry could easily produce cars at least twice as efficient ?we would need many fewer tankers crossing the oceans each year.If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.63.What is the passage mainly talking about?A.Oil spills pollution.B.What oil pollution is.C.Oil tanker accidents. D.How to reduce oil pollution. 64.How does the author support the idea that oil spills are not as serious as people believe?A.By giving a description.B.By making an argument.C.By giving an example.D.By drawing a diagram.65.What does the underlined word "risk" in Paragraph 5 refer to?A.Transportation depending more on oil.B.Poisonous oil breaking down naturally.C.Millions of tons of oil spilling into the sea.D.More environmental damage being caused.66.Which suggestion, is made for reducing oil tank accidents according to the passage?A.We should build safer tankers in the near future.B.We should develop new technologies to cut oil use.C.Tankers should not be allowed to sail near the coastlines.D.Countries should build more oil pipelines under the sea.DRecently there was a major discovery in the scientific research—the mapping of all DNA in a human gene (基因)is complete.Couple of years ago, this seems an impossible task for scientist to accomplish.All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away.Human cloning has always been a topic of argument, in terms of morality or religion.Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning.If the clone was free of genetic limitations.then the other clone would be as well.The latter could foe inserted in the woman and allowed to ripen to term.Moreover, cloning would enable women, who can't get pregnant, to have children of their own.Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs.This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more)organ (s).It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.Arguments against cloning are also on a perfectly practical side.Primarily, I believe that cloning would step in the normal "cycle" of life.There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development—the fundamental reason how living things naturally adapt to the ever-changing environment.Life processes failing to do so might result in untimely disappearance.Furthermore, cloning would make the uniqueness that each one of us possesses disappear.Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would beregarded as "objects" rather than people in the society.Scientists haven't 100 per cent.guaranteed that the first cloned humans will be normal.Thus this could result in introduction of additional limitations in the human "gene-pool".Regarding such arguable topics in "black or white" approach seems very innocent to me personally.We should rather try to look at all "shades" of it.I believe that cloning is only legal if its purpose is for cloning organs; not humans.Then we could regard this as for "saving life" instead of "creating life".I believe cloning humans is morally and socially unacceptable.67.Which of the following is true according to the passage?A.Genetic limitation will be beneficial for some women.B.A large number of genes will prevent us from developing.C.Prohibition of cloning might limit the freedom of scientists.D.First cloned humans might be normal according to scientists.68.What's the author's opinion on cloning?A.Cloning should be entirely banned.B.Cloning should be used in creating life.C.Cloning will take away the right to reproduce.D.Cloning is acceptable if it is used for cloning organs.69.Where can you read this article?A.In a story book.B.In a magazine.C.In a science fiction.D.In a brochure.70.Which of the following shows thestructure of the passage?第二节(共5小题;每小题2分,共10分)On a typical hot August day in Xianyou County, Fujian Province, Zeng Demei, a retired worker in his seventies, hurries down a busy street.In his hand is a black leather bag.Zeng opens his bag, taking out two forms.71 Each of the forms contains detailed information of a student.On his arrival two hours later a woman greets him and leads him to her office where another man is waiting.They are the two village officials.They inspect the forms handed to them by Zeng and immediately recognize the girls.72 ? "It’s a pity but it doesn't matter." says Zeng, who wastes no time in deciding to look for the remaining child, Su Qiuju.After half an hour, they stop outside a small house made of mud brick.A middle-aged man and a girl in a faded pink dress greet them.Su Qiuju is eight years old.She was forced to drop out of school after both her parents died.She is now living with her uncle who cannot afford his own children's education.However, the year of education Su Qiuju did complete was a successful one.73 .When they are about to leave, Zeng says, "I must find a supporter for this girl to sponsor her education." Zeng has made it his retirement task to help children complete their schooling.Back in 1999, Zeng took part in a campaign started by the local women's organization to help students from poor families.74 His task had begun and since then he has spent his time persuading his friends and neighbors and others to donate money."To me, children's education is the most important.75 I have to find sufficient funding before the school opens in September."When asked how long he will keep up his vital work as the community's guardian angel, he has a simple reply." Not until my eyes can't see, and my feet can't move."A.They were having problems with their schoolworkB.These are for the two girls he's going to visit this morningC.They live in a small village not very far, though only one of the girls is still living at homeD.She displayed a talent for handwriting, writing her three-character name neatly and beautifullyE.The thought of students dropping out of school bothers me so much that I can't get to sleep at nightF.Of course, some people question why I would want to give up my retirement to go to so much trouble G.He was so overcome by the tough situation of many poor children ?that he donated all his money to help out a girl第四部分:书面表达(共两节,35分)第一节:情景作文(20分)假设你是红星中学高三(1)班的班长李华,你们全班同学在“五一节”放假期间开展了“体验一天低碳生活”的活动。

北大附中河南分校2013高考押题语文试题本试卷分第Ⅰ卷(阅读题)和第Ⅱ卷(表达题)两部分。
其中第Ⅰ卷第三、四大题为选考题,其它题为必考题。
第Ⅰ卷阅读题甲必考题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1-3题。
书会是宋代与科举有关的会社名称,或称课会,或称课社,或称文会。
它和乡校、家塾、舍馆一样都是民间开办的学校,与宗学、京学、县学等国立学校并存而补充之。
每遇大比之年,书会等民办学校也有人中榜及第,确实与科举考试有密切联系。
抑或受到宋代都市文艺商品化趋势的左右,抑或为了解决自身的生存问题,书会渐渐地由读书吟课的场所转变为从事文艺底本创作和伎艺表演的民间自发组织。
宋代的书会应不少。
由于书会渐渐走向专门化,以致被人们视同为一般的‚行会‛,且统称之为‚社会‛。
书会中从事伎艺底本创作的人称之为书会先生。
从有关资料看,书会先生据其专长,各有所司,分工明确。
宋代书会先生一般是没有功名而精于文艺的民间文人和艺人。
他们通常按照自己的审美认识和道德评价标准去进行文艺创作,并以获得商业利润为创作目的,即以文艺创作为谋生的手段。
因此.他们是一个职业化的、自治性的民间文艺创作群体。
他们的生活是自由的,甚至是放纵的。
北宋词人柳永可谓是书会先生的先驱。
他早年浪迹市井,放骸坊曲,为歌妓作词的经历与后代书会先生的生活方式无甚差异。
宋代书会先生创作的作品应该不少,而由于失载和散佚.今天能确认为书会先生创作的作品已不多,如小说《简帖和尚》、鼓子词《刎颈鸳鸯会》、戏文《张协状元》及一些曲子词和赚词。
从现存的资料看,词是宋代所有伎艺作品的重要组成部分,往往决定着伎艺作品的艺术品位和语言风格。
而伎艺作品质量的提高也是词的质量的提高,伎艺形式的创新也是词体的创新。
书会的创作和表演有助于词的传播和发展,尤其是鼓子词、唱赚和戏文的创作,导致了词体的发展和演变,即由单章体向联章体、套曲体、戏曲体嬗变。
书会先生活动的区域一般在大都市,其‚衣食父母‛(作品的消费者)主要是都市居民。

1、阅读下面的文字,完成下面小题。
可燃冰可以看成是高度压缩的固态天然气,遇火即可燃烧。
同等条件下,煤、石油、天然气燃烧产生的能量比它要少数十倍,而且燃烧后不产生任何污染物质,这让科学家们如获至宝,把它称作“属于未来的能源”。
可燃冰是迄今为止海底最具价值的矿产资源,它在海底分布的范围约占海洋总面积的10%,足够人类使用1000年。
然而可燃冰的形成条件极为,温度不能太高,压力不能太大,一般在浅海底层沉积物、深海大陆斜坡沉积地层中才具备这种条件,因此开采极为困难。
尽管人类地寻求最好的开采方式,但开采量还是。
而且如果“可燃冰”在开采中发生泄漏,分解出来的甲烷气体从海水释放到大气层,将使全球温室效应问题更趋严重,后果不堪设想。
可见,( ),只有合理地、科学地开发和利用,“可燃冰”才会真正地为人类造福。
我国对可燃冰的试开采起步较晚,却,曾在南海海域进行的“可燃冰”试开采中,连续产气22天,从而成为全球海域“可燃冰”试开采连续产气时间最长的国家。
1.文中画横线的句子有语病,下列修改最恰当的一项是A.同等条件下,煤、石油、天然气燃烧产生的能量比它要少数十倍,而且燃烧后几乎不产生任何污染物质B.同等条件下,它燃烧产生的能量比煤、石油、天然气要多出数十倍,而且燃烧后几乎不产生任何污染物质C.同等条件下,它燃烧产生的能量比煤、石油、天然气要多出数十倍,而且燃烧后不产生任何污染物质D.同等条件下,它燃烧产生的能量比煤、石油、天然气要多出数十倍,而且燃烧后绝不产牛任何污染物质2.依次填入文中横线上的词语,全都恰当的一项是A.苛刻殚精竭虑微不足道后米居上B.尖刻殚精竭虑微乎其微青出于蓝C.苛刻千方百计微乎其微后来居上D.尖刻千方百计微不足道青出于蓝3.下列填入文中括号内的语句,衔接最恰当的一项是A.“可燃冰”带给人类的不仪是新的希望,还有新的挑战B.“可燃冰”在带给人类新的希望的同时,更多的是新的挑战C.“可燃冰”带给人类的不仅是新的挑战,还有新的希望D.“可燃冰”在带给人类新的挑战的同时,更多的是新的希望2、阅读下面这首宋诗,完成下面小题。

”1.阅读《荒漠中的苇》一文,完成后面问题。
(共16分)荒漠中的苇王剑冰①汽车穿行于茫茫戈壁已经很久了。
人们初开始的兴趣早已变成了朦胧的睡意。
公路像条细细的带子在沙漠中甩来甩去,不知尽头在何处。
有人不停地在后悔,应该走另一条国道的,是我等少数几个出的点子,说走这条路可以看到五彩城。
远远的五彩城直到我们走到了天黑,看到一颗好大的月亮,也没有见到它的踪影,旅途上的事情是不能凭美丽的想象来完成的。
慢慢地我也没有了什么兴趣。
除了沙漠还是沙漠,而且沙漠的颜色还不是金黄色的,很多都是粗糙的暗褐色的沙石,在公路的两边铺向无尽的远方。
胡杨呢?红柳呢?几乎看不到什么植被,偶尔的几株沙棘,一晃就过去了。
有时出现的不高的丘陵,也仅够让视线有个起伏的弧度。
沙海茫茫,真正是茫茫了。
②窄窄的戈壁公路上跑着的几乎就是我们这一辆汽车,弱小的一叶扁舟样地在大海的波涛中翻涌。
③中间在什么地方吃了一顿午饭,然后就昏昏沉沉睡着了。
醒来已是半下午了,车子还是不急不躁地跑着。
我又一次地把头靠在窗户上,无聊地看着已不成风景的风景。
就在这时,我竟然看到了一种熟悉的植物,是的,是那种水乡才能看到的植物——苇!起先我有点不相信自己的眼睛,以为是看错了,当这种植物又一次在我的视线中出现的时候,我真正地看清了,是苇。
④在我的感觉里,苇是属于弱者,弱者都是以群居的形式出现的,所谓“芸芸众生”。
群居才能产生勇气,才能产生平衡,才能产生力量,才会便于生存。
苇便是一种群像的结合体,荡漾是她的形容词。
我曾在双台河口湿地保护区,在我的家乡渤海湾,在孙犁笔下的白洋淀,都看到过面积逾十万亩甚至百万亩的大芦苇荡。
那一望无际的芦苇,像纤腰袅娜的女子,一群群相拥相携地在风中悠悠起舞。
“蒹葭苍苍,白露为霜。
所谓伊人,在水一方。
”《诗经》中对一位玉人的思念也是以这美丽的植物为衬物。
作为一种最为古老的植物,苇给人们带来的总是美好的向往。
很多的女孩借用了苇的名字,那是一种带有情感的、内涵丰富的、柔韧的、温馨的表达与体现。
⑤可眼前这些苇却显得这般瘦削,不成气势。
就像初生小女的头发,稀稀落落地表明着生命的再生。
或像耄耋老者,以几许羊胡迎风,扬看着不多的时日。
我想象不到在这样荒凉(不只是荒凉,简直是恐怖)的地方,怎么会有苇的植物生长。
是鸟的羽翅?是风的神力?她们真的不该诞生在这里。
在白洋淀、沙家浜,苇正牵裳起舞,接受着游人的赞叹,在渤海湾、黄海滩,苇也是丰足地吸吮着大地的乳汁,欢快地歌唱。
⑥这该是植物中的弱女子啊,给她一片(不,哪怕是一点)水,她就敢生根、发芽、开花,摇曳出一片星火,一片阳光。
那确实是一小片水,好像是修路开挖出的低洼地,仅仅是存留的一点点雨水,而绝不会是人为的故意,她们就结伴地生长起来,那是多么少的伴儿啊。
但女子们还是愿意有伴的,这是她们的天性。
孤芳自赏的苇似乎不称为苇,况且在这样的地方她们别说孤芳,连群艳也无可夺目。
如果不是我惺忪中的一瞥,一个王姓男子也就同她们连一目的交情也错过了。
⑦那片水已经剩了一点点,而她们的长大,还不是借助那一点水吗?看她们的样子,也就是刚刚过了童年而进入了青春期。
那可是戈壁滩,是茫茫大漠,她们会摇曳、会挣扎多久呢?水涸地裂,沙丘涌动,她们都活不了。
我已经看到,离水稍远的几株已经干枯颓折。
⑧不过我想,既然作为一种生命,站立于这个世界上,就有她生命存在的意义和可能。
这个生命就会不讲方式,不图后果地向上生长,直至呼出最后一息。
苇,或被风收去,或被沙掩埋,都会以她最后的努力,度过她最美丽的时光。
苇,你的意思不是萎,是伟!想起金克木《生命》一诗中有一句“生命是低气压的太息,是伴着芦苇啜泣的哈欠。
”暗自笑了,这不知写于何时何背景的诗句,有些明了又有些不明,我这时倒是想改一句:“生命是伴着啜泣与哈欠的芦苇。
”⑨西部,戈壁,荒漠,苇,我把这样的字眼在寂寞的旅途上相连,竟就连出了一种美妙的景象。
【小题1】本文主体是写“苇”,而开篇却用较多笔墨写了“荒漠”,这样写有什么用意?(3分)【小题2】第(4)段中“苇便是一种群像的结合体,荡漾是她的形容词。

(14分)先刷干净手里的瓶子姜炳炎①这是一个人人追求成功的时代。
以往我们只看到成功人士的光鲜面,而其中的历练、积累、艰辛却鲜为人知。
②1975年,19岁高中毕业的金志国被分配到青岛啤酒厂刷酒瓶。
在当时,高中文化已不算低,他对此深感委屈,刷的酒瓶常被返工。
一次又被质检员指责后,他将酒瓶摔地上说:“我不伺候它了!”眼看冲突就要爆发。
这时一位老师傅急忙把他拉过来,拿着瓶子问:“小金,你爹喝啤酒吗?”金志国回答肯定。
“那好,你现在就要把瓶子刷好,因为它装的酒可能被你爹喝,你不希望老人家喝那些用不干净的酒瓶装的酒吧?连这样简单工作都做不好,谁相信你能做好别的事?”老师傅边说边认真地刷着酒瓶,给他做榜样。
③“目标再远,也要先从刷瓶子开始。
”老师傅的话,一直激励着金志国。
从此,金志国的态度明显转变,不仅再没返工,还琢磨着怎样刷瓶子既干净又效率高,他不断地成长,直至后来担任青岛啤酒厂的总裁、董事长。
④“不积跬步,无以至千里;不积小流,无以成江海”的千年古训,至今仍是至理名言。
小酒瓶蕴含奋发的智慧。
奋发来自远大的目标,没有目标,就没有方向,就没有动力。
当选青啤董事长的那天,金志国向员工讲起了当年的经历:“我自己的目标,就是从刷瓶子开始的。
我做洗瓶工的那段日子,非常快乐,高效地创造了让一排排啤酒瓶摆放整齐、各就各位的“神话”。
继而他幽默地说:“我这董事长没有什么特长,就是刷瓶,是认认真真地刷瓶。
从今天起,我要把青岛啤酒这个瓶刷得比别人家的酒瓶都干净、都漂亮。
当然,这需要大家把自己手里的瓶子也都刷得干净和漂亮。
⑤小酒瓶包含坚强的智慧。
大自然中,一粒种子未落沃土而入缝隙,它不屈地穿过岩石绽放绿色,足以辉映整个春天。
同样,人处逆境时,坚强尤为可贵。
霍金轮椅上的美丽人生,海伦黑暗里寻求光明,司马迁隐忍后重于泰山的鸿篇巨制,苦难中的史铁生不懈地追问……坚强,成就生命的高度。
⑥小酒瓶充实激情的智慧。
刷酒瓶其实是一项简单的工作。
周而复始,往返循环,让不少人产生厌倦心理。
而金志国却是用激情刷瓶子。
我们常说:“心有多大,舞台就有多大。
”西方也有这样的谚语:“你有自信就年轻,畏惧就年老;有希望就年轻,绝望就年老;岁月刻蚀的不过是你的肌肤,但如果失去了激情,你的灵魂就不再年轻。
”凭着这种把简单事情做到极致的精神,金志国提升的不仅是工作质量,还有人生的境界和做人的价值。
⑦细想来,每一个人的工作和生活,都是一个要刷的酒瓶,我们只要全心全意地把它刷得干净漂亮,这样装的酒才会香醇可口。
