一、现代文阅读(一)论述类文本阅读(本题共3小题)阅读下面的文字,完成1~3题。
随着互联网时代的飞速发展,词语的传播速度变得更快更广。
眼下我们正处于一个乐此不疲发明各种网络缩略语的时代。
诸如“awsl”之类的高频网络用语累计超过330万次。
“awsl”,源于“啊,我死了”的拼音首字母缩写,表达了年轻人在感受到“惊讶、兴奋、快乐”等各种喜爱之情时的强烈情绪。
对诸如此类的缩略语,从汉语汉字的语言规范性或“纯洁性”出发,持不赞同态度的人不少,有人说缩略语其实是把汉字原本的模样弄丢了。
网络缩略语的形成与互联网的特性密不可分。
英国著名演化生物学家理查德·道金斯在《自私的基因》中提出“模因”概念:文化的基本单位通过非遗传的方式,特别是模仿而得到传递。
随着互联网技术的发展,模因从一个大脑传递到另一个大脑的过程变得极为简单,甚至可以用“病毒式传播”来形容。
网络传播的特点就是不断复制扩散,而复制过程中往往会再创造,比如“awsl”在传播过程中又衍生出“阿伟瘦了”“啊我睡了”等近十种脑洞大开的解读。
网络复制的简单便捷,以及在复制过程中的创新再造,使更多的网友由被动受众与旁观者变成直接参与者和行动者,最终成为一场集体娱乐的狂欢。
网络缩略语的流行作为一种文化现象,表达出年轻人情绪外泄与自我张扬,他们在追求时尚的过程中实现了内在的娱乐。
当某种流行语在一定的群体中开始流行的时候,从众心理会让更多的人接纳并使用这些流行语,以表明自己与时代潮流同步,同时避免被同一群体排斥,这种自我认同的强烈愿望使其更愿意投入到流行与时尚之中。

He was called by New Yorkers "the Little Flower" because he was short and always wore a carnation(康乃馨). He was a colorful character who used to ride the New York City fire trucks, raid(突袭) places that were illegal to make and sell alcohol with the police department, take homeless children to baseball games, and whenever the New York newspapers were on strike, he would go on the radio and read the Sunday funnies to the kids.One bitterly cold night in January of 1935, the mayor turned up at a night court that served the poorest district of the city. LaGuardia dismissed(赶走) the judge for the evening and took over the bench himself. Within a few minutes, an old woman wasbrought before him, charged(控告) with stealing a loaf of bread. She told LaGuardia that her daughter's husband had deserted her, that her daughter was sick, and that her two grandchildren were extremely hungry. But the shopkeeper, from whom the bread was stolen, refused to drop the charges. “It's a bad neighborhood,Your Honor,” the man told the mayor. She's got to be punished to teach other people around here a lesson.LaGuardia sighed. He turned to the woman and said, “I've got to punish you. The law makes no exceptions---ten dollars or ten days in prison.” But even as he pronounced sentence, the mayor reached into his pocket. He took out a bill and said, "Here is the ten-dollar fine which I now pay for the defendant(被告); and furthermore, I am going to fine everyone in this courtroom fifty cents for living in a town where a person has to steal bread so that her grandchildren can eat. Mr. Bailiff, collect the fines to the defendant.”So the following day the New York City newspaper reported that $47.50 was turned over to an old woman who had stolen a loaf of bread.4.What can we know about Fiorello LaGuardia from Paragraph 1?A.He was keen on public affairs.B.He was interested in planting carnations.C.He was a mayor for only a very short time.D.He was popular for his unique dressing style.5.Why did the old woman steal the bread?A.To test the justice of the court.B.To cure her daughter.C.To punish the cruel shopkeeper.D.To feed her grandchildren.6.What was the shopkeeper's excuse for insisting on the charges?A.To show the mayor the danger of stealing.B.To prevent similar things from happening.C.To make people understand the spirit of law.D.To punish the old woman's family indirectly.7.Which of the following can best describe Fiorello LaGuardia?A.Kind-hearted and wise.B.Confident and unselfish.C.Optimistic and responsible.D.Knowledgeable and ambitious.CYou can relax if remembering everything isn't your strong suit. Recent research makes the case that being forgetful can be a strength—in fact, selective memory can even be a sign of stronger intelligence.Traditional research on memory has focused on the advantages of remembering everything. But looking through years of recent memory data, researchers found that the neurobiology of forgetting can be just as important to our decision-making as what our minds choose to remember.Making intelligent decisions doesn't mean you need to have all the information at hand. It just means you need to hold onto the most valuable information. And that means clearing up space in your memory palace for the most up-to-date information on clients and situations. Our brains do this by creating new neurons(神经元) in our hippocampus, which have the power to overwrite(重写)existing memories that are influencing our decision-making.If you want to increase the number of new neurons in our brain's learning region, try exercising. Some aerobic exercise like jogging, power walking and swimming has been found to increase the number of neurons making important connections in our brains.When we forget the names of certain clients or details about old jobs, the brain is making a choice that these details don't matter. Although too much forgetfulness can be a cause for concern, the occasional lost detail can be a sign of a perfectly healthy memory system. The researchers found that our brains facilitate decision-making by stopping us from focusing too much on unimportant past details. Instead, the brain helps us remember the most important part of a conversation.We can get blamed for being absent-minded when we forget past events in perfect detail. These findings show us that total recall(记忆) can be overvalued. Our brains are working smarter when they aim to remember the right stories, not every story.8.How can we help our brains produce more neurons?A.By having deep sleep frequently.B.By learning new skills constantly.C.By doing mental labor repeatedly.D.By practicing swimming regularly.9.Which of the following can best replace "facilitate" underlined in paragraph 5?A.put offB.repeatC.promoteD.overuse10.What conclusion can be drawn from the text?A.Memory loss is well worth noticing.B.We shouldn't stress total recall too much.C.Decisions can't be made without memories.D.Forgetting is even more important than remembering.11.What can be a suitable title for the text?A.Caution: do remember to forgetB.Why and how people choose to forgetC.Want to become smarter? Learn to forgetD.Being forgetful might mean you are smarterDWorld travel has moved on to a new level as new websites spring up to enable travelers to plan their trips online. Virtual tourism is the latest name of the game and although relatively new, it has seen some tourism websites grow to host over one-million users.Typically, this development features a website that contains the answers to almost any tourism question. Tips and information are not provided by a single source, such as the website host, but rather from travelers themselves---often in the thousands. This has proven to be exceptionally beneficial for would-be travelers who are seeking information on questions such as where to find the best museum or beach; whether it is better to tour Brussels with a bicycle or on foot; and which exchange rate bureaus are available in Italy. Questions about food and restaurants, tourist spots, safety, accommodation, and others are all answered. In addition, posted tips promote better preparation, such as what to pack when heading for Sicily(西西里岛).Apart from the useful tips, visual images and virtual tours have also been made available. If you'd like to visit the Eiffel Tower, it's a good idea to view the surrounding areas, to pick a safer train route, or to know that it's very close to the Seine River and that a walk along it would enhance the experience.Virtual tours have sprung up globally. In South Africa, John Gore established the Virtual Tour Guide in November last year. On his blog, Gore was quoted a saying, "The world is panoramic(全景的).” “We are able to turn our heads and look in all directions and get a feel for where we are, but the typical photograph cannot show or describe that experience completely.”However, there is an answer---technology makes it possible to share the world around us in a 360 degree panoramic way, whichreally makes the viewer feel as though he or she is really there.12. From the second paragraph we know ____________.A. we can solve any problem on websitesB. websites offer all the tips and informationC. we can get all our questions answered onlineD. we can get many tips about tourism on websites13. What does the underlined word "sprung up" most probably mean?A. Appeared.B. Moved.C. Competed.D. Reduced.14. What makes us see the world in a panoramic way?A. Information.B. Photograph.C. Technology.D. Virtual images.15.What's the main purpose of the passage?A. To introduce the history of virtual tourism.B. To give some advice on virtual tourism online.C. To attract more tourists to travel to the world.D. To teach us how to establish a website online.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

河南省鹤壁市高级中学2020_2021学年高一语文上学期第二次段考试题
河南省鹤壁市高级中学2020-2021学年高一语文上学期第二次段考试题一、现代文阅读(36分)(一)论述类文本阅读(本题共3小题,9分)阅读下面的文字,完成1一3题。
阳明心学的当代意义,其实是由其本身的特质决定的。
阳明心学本身就是自由活泼、积极主动的,极具创造性。
阳明心学的第一个根本特点,就是强调人的道德主体性,即道德自由。
阳明心学告诉我们,良知是心之本体,知行的本体。
人是有良知的,人应该不断地发明良知、实践良知,振起人的精神生命。
“致良知”是学问修养的灵魂与第一原则。
王阳明告诉了我们一条道德人格的上升通道,彰显了人性本来的光辉,强调人性的光辉不仅要照亮我们自身,甚至还要照亮他人。
人不应该向下沉沦,不能为物欲所遮蔽,不能陷入异化之中而否定自我的人性。
这一点,可以唤醒现代人冷漠的、功利的、庸俗化的心灵,拯救当下的生态危机、信仰危机、道德伦理危机。
王阳明对自然万物,包括草木、鸟兽、山水、瓦石等,都有一种深厚的生命关怀,强调“仁者以天地万物为一体”。
他发扬了孔子的“仁爱”与孟子的“仁民爱物”思想,在他看来,不仅是动植物等自然之物,甚至人造之物(如瓦),因其源于自然,又是人生存的不可或缺的物品,也都有生命,都有存在权利,都要顾惜。
天地万物是一个生命整体,虽然人类必须取用动植物,但动植物仍有自身的价值,体现了一种普遍的道德关怀。
王阳明的“致良知”,就是把“真诚恻怛”的仁爱之心发挥、扩充、实现出来,去应对万物,使万物各安其位,各遂其性。
大众普遍存在这样的问题:认可书本上、讲堂上的道理,但离开书本和讲堂后却难以躬行践履。
“知行合一”其实正是针对这个问题而来的。
做不到是因为还没能理会得透,理会透了自然做得到。
阳明心学告诉我们,要在日用伦常之间,在礼乐刑政之间,将天地万物一体之仁发用出来,用来敬老爱亲,用来修身齐家。
用来尽伦尽职,为政理事。
做一分,就体认一分良知,体认一分良知,就要行一分。
这一点,可以赋予今人实践道德、完善自我的勇气。
