山西省临猗县临晋中学2019-2020高一语文9月月考试题

山西省临猗县临晋中学2019-2020高一语文9月月考试题

山西省临猗县临晋中学2019—2020学年高一语文9月月考试题一、现代文阅读(15分)(一)论述类文本阅读(共3个小题,9分)阅读下面的文字,完成1-3题。

自秦始皇统一中国后,中国古代社会就开始它漫长的封建社会发展史。

秦王朝的国运不长,而且秦王朝推行“以法为教”、“以吏为师”的文教政策,所以在家庭教育方面没有什么建树。

但是,随着汉王朝的建立和封建社会的持久安定,加上长期推行“独尊儒术”的文教政策,采取科举取士和以经术取士,注重以三纲五常之教统治人们思想和以孝道之教稳定家庭与社会的伦理道德关系,所以家庭教育得到迅速发展,并且日渐形成了它的特色。

魏晋南北朝时期,除了汉代形成的以经学作为主要内容的教育继续推行之外,由于统治阶级和一些知识分子的提倡,玄学、佛学、史学以及一些自然科学技艺及生产技艺等,也进入了不同阶层的家庭教育范围.总体说来,魏晋南北朝时期,由于战乱频仍、社会动荡不安,家庭的生产与生活也缺乏稳定性,所以这一时期的家庭教育与汉代相比,相差甚远,尤其是统治阶层受“九品中正”制取士制度的影响,豪门士族的子孙天生就是“上三品"的高官世袭者,而寒门士族的子孙即使学富五车也难以入上品,至于平民百姓的子孙就更不在话下,由此所造成的“读书无用"的观念也渗透到不同阶级和阶层的家庭教育实践中,造成诗书教育日渐衰落的局面。

汉魏六朝的家庭教育,尽管有由盛转衰的趋向,但是由于封建社会制度和家庭制度不断发展和完善,所以家庭教育的阶级性和等级性也日益明显起来。

形成了以皇家宗室为主体的贵族家庭教育,以及在职文官为代表的官宦家庭教育和广大生活在社会底层的平民家庭教育的家教制度.这三类家庭教育,一直沿续和发展到清末,在客观上对我国封建社会政治、道德、家庭乃至社会秩序等,都产生了深刻的影响。

皇家的教育主要在于培养储君,所以皇太子及诸王子的教育受到特别的重视,乃至成为国家政治的一件大事。

皇家的家教具有特权性,在措施上一是尽一切努力把全国图书搜集在皇家图书馆,垄断文化以作为皇家宗室的教材;二是收买天下第一流的学者充任宫廷教师;三是建立一整套宫廷教师制度和完备的教学制度。

2019届山西省临猗县临晋中学高三9月月考英语试卷

临晋中学2019届高三年级9月份月考英语试题一阅读理解(每小题3分,共60分)A.Suppose you’re in a rush¸felling tired¸not paying attention to your screen¸and you send an email that could get you in trouble.Realisation will probably set in seconds after you’ve clicked “send”.You freeze in horrors and burn with shame.What to do? Here are four common email accidents¸and how to recover.Clicking “send” too soonDon’t waste your time trying to find out if the receivers has read it yet.Write another email as swiftly as you can and send it with a brief explaining that this is the correct version and the previous version should be ignored.Writing the wrong nameThe sooner you notice¸the better.Respond quickly and briefly¸apologizing for your mistake.Keep the tone measured: don’t handle it too lightly¸as people can be offened¸especially if your error suggests a misunderstanding of their culture(i.e.incorrect ordering of Chinese names).Clicking “reply all” unintentionallyYou accidentally reveal(透露)to entire company what menu choices you would prefer at the staff Christmas dinner¸or what holiday you’d like to take.In this instance¸the best solution is to send a quick¸light-hearted apology to explain your awkwardness.But it can quickly rise to something worse¸when everyone starts hitting “reply all” to join in a long and unpleasant conversation.In this instance¸step away from your keyboard to allow everyone to calm down.Sending an offensive message to its subjectThe most awkward email mistake is usually committed in anger.You write an unkind message about someone¸intending to send it to a friend¸but accidentally send it to the person you’re discussing.In that case ¸ask to speak in person as soon as possible and say sorry.Explain your frustrations calmly and sensibly—see it as an opportunity to clear up any difficulties you may have with this person.1.After realising an email accident¸you are likely to feel _______.A.curious B.tired C.awful D.funny2.If you have written the wrong name in an email¸it is best to ________.A.apologise in a serious manner B.tell the receiver to ignore the errorC.learn to write the name correctly D.send a short notice to everyone3.What should you do when an unpleasant conversation is started by your “reply all” email?A.Try offering other choices.B.Avoid further involvement.C.Meet other staff members.D.Make a light-hearted apology.4.How should you deal with the problem caused by an offensive email?A.By promising not to offend the receiver again.B.By seeking support from the receiver’s friends.C.By asking the receiver to control his anger.D.By talking to the receiver face to face.5.What is the passage mainly about?A.Defining email errors.B.Reducing email mistakes.C.Handling email accidents.D.Improving email writing.BGetting less sleep has become a bad habit for most American kids.According to a new survey(调查) by the National Sleep Foundation¸51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights¸even though they have to get up early.Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day¸and 15% said they had fallen asleep at school.How much sleep you need depends a lot on your age.Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours.For most school-age children¸ten hours is ideal(理想的).But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours.And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.“More children are going to bed with TVs on¸and there are more opportunities(机会) to stay awake¸with more homework¸the Internet and the phone¸” says Dr.Mary Carskadon¸a sleep researcher at Brown University Medical School.She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep.0ther experts say part of the problem is chemical.Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics¸but also make it hard for teenagers to fall asleep before 11 pm.Because sleepiness is such a problem for teenagers¸some school districts have decided to start high school classes later than they used to.Three years ago¸schools in Edina¸Minnesota¸changed the start time from 7:25 am to 8:30 am.Students¸parents and teachers are pleased with the results.6.What is the new National Sleep Foundation survey on?A.American kids’ sleeping habits.B.Teenagers’ sleep-related diseases.C.Activities to prevent sleeplessness.D.Learning problems and lack of sleep.7.How many hours of sleep do 11-year-olds need every day?A.7 hours.B.8 hours.C.10 hours.D.18 hours.8.Why do teenagers go to sleep late according to Carskadon?A.They are affected by certain body chemicals.B.They tend to do things that excite them.C.They follow their parents’ examples.D.They don’t need to go to school early.CPassenger pigeons(旅鸽) once flew over much of the United States in unbelievable numbers.Written accounts from the 18th and 19th centuries described flocks(群) so large that they darkened the sky for hours.It was calculated that when its population reached its highest point, there were more than 3 billion passenger pigeons – a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant bird in the world.Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.Sadly, the abundance of passenger pigeons may have been their undoing.Where the birds were most abundant, people believed there was an ever-lasting supply and killed them by the thousands.Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time.The birds were shipped to large cities and sold in restaurants.By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered (驱散) the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline.Soon the great flocks were gone, never to be seen again.In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years.The last confirmed wild pigeon in the United States was shot by a boy in Pike County, 0hio, in 1900.For a time, a few birds survived under human care.The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden on September 1, 1914.9.In the 18th and early 19th centuries, passenger pigeons _______.A.were the biggest bird in the world B.lived mainly in the south of AmericaC.did great harm to the natural environmentD.were the largest bird population in the US10.The underlined word “undoing” probably refers to the pigeons’ ______.A.escape B.ruin C.liberation D.evolution11.What was the main reason for people to kill passenger pigeons?A.To seek pleasure.B.To save other birds.C.To make money.D.To protect crops.12.What can we infer about the law passed in Michigan?A.It was ignored by the public.B.It was declared too late.C.It was unfair.D.It was strict.DHollywood’s theory that machines with evil(邪恶) minds will drive armies of killer robots is just silly.The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want.In 1960 a well-known mathematician Norbert Wiener¸who founded the field of cybernetics(控制论)¸put it this way:“If we use¸to achieve our purposes¸a mechanical agency with whose operation we cannot effectively interfere(干预)¸we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”A machine with a specific purpose has another quality¸one that we usually associate with living things:a wish to preserve its own existence.For the machine¸this quality is not in-born¸nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead.So if we send out a robot with the single instruction of fetching coffee¸it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task.If we are not careful¸then¸we could face a kind of global chess match against very determined¸super intelligent machines whose objectives conflict with our own¸with the real world as the chessboard.The possibility of entering into and losing such a match should concentrate the minds of computer scientists.Some researchers argue that we can seal the machines inside a kind of firewall¸using them to answer difficult questions but never allowing them to affect the real world.Unfortunately¸that plan seems unlikely to work:we have yet to invent a firewall that is secure against ordinary humans¸let alone super intelligent machines.Solving the safety problem well enough to move forward in AI seems to be possible but not easy.There are probably decades in which to plan for the arrival of super intelligent machines.But the problem should not be dismissed out of hand¸as it has been by some AI researchers.Some argue that humans and machines can coexist as long as they work in teams—yet that is not possible unless machines share the goals of humans.0thers say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility.Still others think that super intelligent AI will never happen.0n September 11¸1933¸famous physicist Ernest Rutherford stated¸with confidence¸“Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However¸on September 12¸1933¸physicist Leo Szilard invented the neutron-induced(中子诱导) nuclear chain reaction.13.Paragraph 1 mainly tells us that artificial intelligence may .A.run out of human control B.sati sfy human’s real desiresC.command armies of killer robots D.work faster than a mathematician14.Machines with specific purposes are associated with living things partly because they might be able to .A.prevent themselves from being destroyedB.achieve their original goals independentlyC.do anything successfully with given ordersD.beat humans in international chess matches15.What does the author think of the safety problem of super intelligent machines?A.It will disappear with the development of AI.B.It will get worse with human interference.C.It will be solved but with difficulty.D.It will stay for a decade.E 七选五Money MattersParents should help their children understand money.16 So you may start talking about money when your child shows an interest in buying things,candy or toys,for example.1.The basic function of moneyBegin explaining the basic function of money by showing how people trade money for goods or-services.It is important to show your child how money is traded for the things he wants to have.If he wants to have a toy,give him the money and let him hand the money to the cashier (收银员).17 When your child grows a bit older and understands the basic function of money,you can start explaining more complex ways of using money.2.Money lessonsApproach money lessons with openness and honesty.18 If you must say no to a child's request to spend money,explain,"You have enough toy trucks for now." 0r,if the request is for many different things,say,"You have to make a choice between this toy and that toy."3.19Begin at the grocery store.Pick out two similar brands of a product — a name-brand butter and a generic (无商标产品),for example.You can show your child how to make choices between different brands of a product so that you can save money.20 If he chooses the cheaper brand,allow him to make another purchase with the money saved.Later,you may explain how the more expensive choice leaves less money for other purchases.A.Wise decisionsB.The value of moneyC.Permit the child to choose between them.D.Tell your child why he can — or cannot — have certain things.E.Ask yourself what things that cost money are most important to you.F.Talk about how the money bought the thing after you leave the toy store.G.The best time to teach a child anything about money is when he shows an interest.二完形填空(每小题2分,共40分)If you want to learn a new language¸the very first thing to think about is why.Do you need it for a 21 reason¸such as your job or your studies? 22 perhaps you're interested

从某种意义上说,古文字是对思维进行考古的工具。

古人类主要运用形象进行思维。

这种特点反映在古诗歌中,人们喜欢用比兴来说明某种道理;反映在原始神话中,人们通过具体的故事来说明某个道理,抽象的道理是没用的。

形象思维曾是人类最得心应手的思维方式。

抽象思维是在形象思维的基础上逐步发展起来的。

从文字的创造特点看,绘画文字是最早的文字。

这种文字的主要特点是象形。

不仅中国的古文字用形象来表示,古巴比伦人、古雅玛人、古埃及人等无一不是从象形开始来创造古文字的。

创造文字的时代,人们抽象思维的能力还比较薄弱。

人们进行抽象思维,还很难脱离具体形象来进行,往往要依赖于对形象的类比、比较、联想来进行。

表现在文字的创造上,形与义密切结合在一起,人们是从形象来了解符号的意义的。

文字的产生一方面是以人类抽象思维的能力达到一定水平为基础的。

但另一方面,象形文字又标志着人类抽象思维能力还不发达,这种低下的抽象思维能力不可能创造太抽象的符号。

抽象思维能力的低下还主要表现在古文字上的词类上,表现为形容词的极端贫乏。

从甲古文看,形容词数量相当少,只有白、厚、明、光、赤、美、丽等为数不多的形容词。

事物的性质包含在事物之中,与事物不可分离,只能通过人的思维才能把事物的性质从事物本身分开。

在近代一些少数民族那里,要说热,只能说“像火一样”。

早期文字中的“鱼”字是各种各样的鱼类象形,后来逐渐概括出一种共同的鱼的特征的象形文字,作为各种各样鱼的代表。

早期文字中,几乎每个文字都经历了一定的概括过程。

没有概括过程,就不可能产生一般意义上的文字。

这种概括能力使人们能概括出事物的共同性质,撇开了同类事物之间的差别性、个性和偶然性,产生了最初的种、类概念。

山西省临猗县临晋中学2019届高三语文9月月考试题

山西省临猗县临晋中学2019届高三语文9月月考试题第Ⅰ卷阅读题一、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1~3题。

中国文化的起源众说纷纭,巫起源说是其中之一。

中国文明以农耕文明起家,巫就成了中国文化的母胎。

在一个无法迁徙的农耕部落中,如何消融自然的变化所引起的恐慌,就是这个群体顺利生存下去的关键因素。

人类社会要通过一系列反复的宗教节日与自然发展取得协调一致,“在庆祝节日时,人类社会积极地参加进了季节变化所表现出来的宇宙危机中”。

在顺利度过这个宇宙危机的仪式中,巫无疑起到了决定性的作用,因为他是宇宙危机以及协调危机仪式中的唯一解释者,他阐发着来自宇宙自然之神的意见以及宇宙危机协调的效果,他的阐释决定了部落是生活在希望还是恐惧中。

在氏族部落时期,巫是部落的领袖,因为通神而为大家信服崇拜,享有崇高的权威。

巫即是萨满,在满语中是智者,也就是拥有智慧的人。

但是此智者非希腊之智者。

希腊智者运用理性和知识,找出对方的逻辑漏洞,在辩论中取胜。

萨满则相反,他的智慧不来自理性和经验,而是来自神灵的启示。

萨满通过一种类似舞蹈的仪式,使神灵附在自己的身上,此时萨满和神灵即为一体,萨满说的话就是神灵的启示。

巫如果想成功解读危机和灾难,在部落平民的眼中,就必须看到危机被解决的实际果效,如洪水退去、干旱结束、日食的太阳完全出现。

如果巫身上仅仅是无理性的疯狂,显然无法实现这么重大的功能。

所以巫除了在仪式中的动作和神灵附体式的颤抖之外,还要有关于天文、农业甚至医病的知识和技能。

那么巫就成了当时知识的掌管者,他们负责解释任何一个引起恐慌的非自然事件,并且使人们看到这种解释的效果,从而使他们从恐惧中走出,进入正常的生产中去。

中国诸子百家的起源,古代史书一直认为诸子出于王官,是周王室的王官流落于民间而成。

其实王官之学也是巫,因为周王室“国之大事,惟祀与戎”,所以巫在那个时代是一切事物的核心,百官皆由巫出。

临猗中学2019--2020学年9月份阶段性考试高二语文试题(考查时间:150分钟满分:150分)一、现代文阅读(36分)(一)论述类文本阅读(3小题,共9分)阅读下面的文字,完成1-3题。

杜甫之所以能有集大成之成就,是因为他有可以集大成之容量。

而其所以能有集大成之容量,最重要的因素,乃在于他生而禀有一种极为难得的健全才性——那就是他的博大、均衡与正常。

杜甫是一位感性与理性兼长并美的诗人,他一方面具有极大极强的感性,可以深入到他接触的任何事物,把握住他所欲攫取的事物之精华;另一方面又有着极清明周至的理性,足以脱出于一切事物的蒙蔽与局限,做到博观兼美而无所偏失。

这种优越的禀赋表现于他的诗中,第一点最可注意的成就,便是其汲取之博与途径之正。

就诗歌体式风格方面而言,古今长短各种诗歌他都能深入撷取尽得其长,而且不为一体所限,更能融会运用,开创变化,千汇万状而无所不工。

我们看他《戏为六绝句》之论诗,以及与当时诸大诗人,如李白、高适、岑参、王维、孟浩然等,酬赠怀念的诗篇中论诗的话,都可看到杜甫采择与欣赏的方面之广;而自其《饮中八仙歌》《曲江三章》《同谷七歌》等作中,则可见到他对各种诗体运用变化之神奇工妙;又如从《自京赴奉先县咏怀五百字》《北征》及“三吏”“三别”等五古之作中,可看到杜甫自汉魏五言古诗变化而出的一种新面貌。

就诗歌内容方面而言,杜甫更是无论妍媸巨细,悲欢忧喜,宇宙的一切人物情态,都能随物赋形,淋漓尽致地收罗笔下而无所不包,如写青莲居士之“飘然思不群”,写空谷佳人之“日暮倚修竹”;写丑拙则“袖露两肘”,写工丽则“燕子风斜”;写玉华宫之荒寂,予人以一片沉哀悲响;写洗兵马之欢忭,写出一片欣奋祝愿之情、其涵蕴之博与变化之多,都足以为其禀赋之博大、均衡与正常的证明。

其次值得注意的,则是杜甫严肃中之幽默与担荷中之欣赏,我以为每一位诗人对于其所面临的悲哀与艰苦,都各有其不同的反应态度,如渊明之任化,太白之腾跃,摩诘之禅解,子厚之抑敛。
