)1。

先秦时期某思想家提出:“以德就列,以官服事,以劳殿赏,量功而分禄、故官无常贵,而民无终贱,有能则举之,无能则下之。

"其思想属于A、强调赏罚的法家思想B。

提倡无为的道家思想C。

提倡道德的儒家思想D。

主张选贤的墨家思想【答案】D【解析】依照材料中“以官服事,以劳殿赏,量功而分禄"得出“尚力”的思想;依照“有能则举之,无能则下之"得出“尚贤"的思想,这一思想家为墨家,故D项正确。

ABC三项均不符合题意,排除、点睛:材料指出,墨子主张依照德能来分配官职名禄,有才能的人“举之”,无才能的人“下之”,如此就“官无常贵,民无终贱”,社会就实现公义了、这体现了墨子对公正至上的强调。

依照所学可知,墨子主张尚贤,是对世卿世禄的否定,有利于实现社会公平、2。

甘肃省武山县三中2018_2019学年高二语文上学期第一次月考试题

甘肃省武山县三中2018_2019学年高二语文上学期第一次月考试题

甘肃省武山县三中2018-2019学年高二语文上学期第一次月考试题注意事项:1.答题前填写好自己的姓名、班级、考号等信息2.请将答案正确填写在答题卡上一、现代文阅读(一)、论述类文本阅读(本题共3小题,9分)从“对话”的视角看中国古代之“家”,不难发现,“家”的功能经历了一个从祭祀、生产再到住所的过程。

换言之,“家”是人与神灵对话、人与自然对话以及人与人对话之所。

家是人与神灵对话的场所。

祭祀对中国古人来说是非常重要的一件事,不仅是对神灵和超自然对象的臣服,也是人与神灵交流的一种方式。

祭祀对象分为三类:天神、地祇、人鬼。

天神称祀,地祇称祭,宗庙称享。

天神地祇由天子祭,诸侯大夫祭山川,士庶只能祭祀祖先和灶神。

祭祀需要场所,而家在很大程度上就是一种祭祀的场所。

《礼记·王制》曰:“天子七庙”,“诸侯五庙”,“大夫三庙”, “士一庙”,“庶人祭于寝”。

普通的老百姓只是“寝祭”。

寝又称为家,寝祭就是家祭。

寝祭在古代是一种普遍的对祖先的祭祀方式。

贵族统治者的庙祭,就是在寝祭基础上形成的。

人们通过这种对话,既可以表达对鬼神的敬畏,也可以表达对美好未来的期盼。

家也是人与自然进行对话的载体,这种对话首先以生产的方式实现。

美国学者史蒂文认为,“家庭在工业化之前是经济生产和交换最重要的商业机构。

每个家庭都或多或少地处于自给自足的状态;每个家庭不同的成员在生产基本物质产品的工作中也是密不可分地联系在一起的”。

夏商周时期,中国最基本的社会制度就是宗族制度。

而宗族作为政治、经济和生活的综合体,成为社会基本组织形式。

此时的个体家庭,则是组成宗族的最基本的单元。

《周礼》记载,西周时期,庶人的具体家庭已经成为一个生产经营单位,只不过土地仍然为宗族所有。

每个个体家庭的人口在2—7人,每家有一个成年男性作为家长,家庭要按照人口服徭役。

当时的个体家庭尚未从宗族中独立出来,在生产上实行的是“耦耕俱耘”的方式。

按照《诗·周颂·良耜》的记载,在宗族内部,个体家庭之间相互形成劳动协作的关系,也就是“一族同时纳谷”,“出必共洫间而耕,入必共族中而居”。

The students were not behaving themselves.B. The heated discussions angered the headmaster.C. He thought the headmaster would scold him.D. The headmaster was looking at his students' papers.4.(8分)CSan Francisco has decided that its city government workers can’t use computer programs that recognize faces. It is the first US city to take such a strong step to keep this technology under control.When a computer system identifies a person from their face in a picture, it’s called “facial recognition” (面部识别). Many police departments use facial recognition. It can be helpful when the police just have a picture of a suspect (嫌疑犯),but no other information. Normally, even with facial recognition the police must have other proof showing that a person is guilty. But many people say facial recognition programs aren’t good enough yet. The programs can usually recognize white men. But they’re not so good at identifying women and people with darker skin. They worry that “false matches” --- when the computer thinks it has identified a person, but it’s wrong --- will make innocent (无罪的) people look like criminals.For companies like Amazon and Microsoft, facial recognition is a big business. Amazon has worked hard to sell their facial recognition to police departments around the US. Microsoft sells tools that allow prisons to watch people inside.To work well, facial recognition programs must have a great number of pictures of people. But most people whose pictures are in the systems never gave permission (许可) for their pictures to be used.Many people worry that using computers to identify or track people will decrease freedom. Now, in many places, facial recognition is used to keep people under control and much of public life is watched on security cameras. Similarly, many cities in America and Europe are also almost completely covered by security cameras. Police officers now often wear cameras on their bodies, recording all the time. It’s usually not clear when governments are using facial recognition and how they are using it.Facial recognition is already being used at airports throughout Europe and in the US. The Department of Homeland Security expects to have picture of 97% of the people flying out of the country in the next four years.As these powerful computer programs become more common, San Francisco’s move to control facial recognition is an unusual and strong move to limit the way governments use computers to watch and control people.28.Why do people worry about facial recognition programs?A.They cannot multiply people’s responsibility.B.They cannot help the police identify good people.C.They will mistake innocent people for bad people.D.They will identify black people instead of white people.29.How can facial recognition programs function effectively?panies should work with each other.B.People should have more pictures taken.C.They should include as many pictures as possible.D.Police departments and prisons should be under control.30.What make people feel their freedom is on the decrease?A.There are the police everywhere.B. A lot of security cameras are used.C. More people are forced to stay at home.D. Governments focus more on facial recognition.31. What’s San Francisco’s attitude towards government workers using facial recognition?A. DisapprovingB. SupportiveC. DoubtfulD. Optimistic5.(8分)DMany people think of the brain as a mystery(神秘).They don’t know much about intelligence and how it works.When they think about what intelligence is, many people believe that a person is born either smart, average, or dumb(愚笨的)—and stays that way for life.But new research shows that the brain is more like a muscle — it changes and gets stronger when you use it.And scientists have been able to show just how the brain grows and gets stronger when you learn.Everyone knows that when you lift weights, your muscles get bigger and you get stronger.A person who can’t lift 20 pounds when they start exercising can get strong enough to lift 100 pounds after working out for a long time.That’s because the muscles become larger and stronger with exercise.And when you stop exercising, the muscles shrink(萎缩)and you get weaker.That’s why people say, “Use it or lose it!”But most people don’t know that when they practice and learn new things, parts of their brain change and get larger a lot like muscles do when they exercise.Inside the cortex (脑皮层)of the brain are billions of tiny nerve cells(神经细胞).Communication between these brain cells is what allows us to think and solve problems.When you learn new things, these tiny connections in the brain actually multiply and get stronger.The more you challenge your mind to learn, the more your brain cells grow.Then, things that you once found very hard or even impossible to do seem to become easy.The result is a stronger and smarter brain.Scientists started thinking that the human brain could develop and change when they studied animals’ brains.They found out that animals who lived in a challenging environment, with other animals and toys to play with, were more “aptitudinal”—they were better at solving problems and learning new things.32.What’s the main idea of the passage?A.Scientists show strong interest in what intelligence is.B.A new study shows the brain can be developed like a muscle.C.Both muscles and the brain are important to humans.D.Intelligence exists in both humans and animals.33.By using such numbers as 20 and 100 in Paragraph 2,the author tries to provethat .A.exercise plays an important role in keeping muscles strongerB.exercise is more important to people than most of the animalsC.everyone can keep healthy if they do enough exercisesD.everyone should learn as many new things as possible34.Like stronger muscles come from exercise, smarter brains need .A.to be well taken care of B.a good communication between personsC.help from scientists D.our learning new things35.What does the underlined word “aptitudinal” in the last paragraph probably mean? A.Strong B.Lovely C.Smart D.Active三、阅读七选五(本题共计1小题,总分10分)6.(10分)How to manage your email inbox36 .We love it and we hate it. We need it and want it, but too often the price we pay is that.

Set a timer on your phone and stick to it.Scan your inbox. 39 At the same time, leave out everything that is unnecessary and answer timely requests first.40 Instead of creating an email, try speaking with the person you want to communicate with.

I was not as rich as before! We moved to the small apartment, and there was only one shower in the bathroom.It was so cold to take a shower in such a cold winter.But I found that if one person took the shower first, the room could get a little warmer.So every day I rushed to the bathroom first.I was thinking that, when she took the shower, the room would get warmer, even if it was only 1℃.Now I cannot give her a comfortable life, take her to good restaurants, or buy expensive dresses for her, but at least, I can give her 1℃ love.21. Why did the couple move to the small apartment?A.Both of them were out of work.B.They wanted to live a better life.C.They were too poor to live in the former house.D.The man could take better care of his business.22.Which of the following can replace the underlined word “exhausted”?A.Tired.B.Worried.C.Devoted.D.Injured.23. What can be inferred from the passage?A.They would live a richer life soonB.The woman would get angry after reading the diary.C.The man would care less about his business.D.The woman misunderstood her husband.24. What's the best title of the passage?A.A Love Story B.Fight for the BathroomC.A Suffering Couple D.1℃ LoveBToday, in many places, like restaurants and hotels, people use Wechat or other kinds of payment to pay for their bills. So some scholars say that the wallet is heading for extinction. It will die off with the generation who read printed newspaper. The kind of shopping where you hand over notes and count out change in return now happens only in small retail(零售) counters, like buying a bar of chocolate or a pint of milk from a corner shop. At the shops where you spend any real money, that money is increasingly abstract. At the most famous retail store Victoria Beckham on Dover Street, you don’t have to stand at any kind of cash register when you decide to pay. The staff are equipped with iPads to take your payment while you relax on a sofa.Wherever you go, you can get an excellent service, if you have the money. But across society, the abstraction of the idea of cash makes me uneasy. Maybe I’m just old-fashioned. But earning money isn’t quick or easy for most of us. Isn’t it a bit weird(怪异的) that spending it should happen in half a blink of an eye?But I’ll leave the economics to the experts. What bothers me about the death of the wallet is the change it reflects in our physical environment. The opposite of a wallet is a smart phone or an iPad. When we pay for anything, instead of digging through pieces of paper and peering into corners in a wallet, what we need to do is to move our fingers left and right. Show your wallet, if you still have one. It may not be here much longer.25.According to the text, customers can pay their bills _________ in big modern stores.A. secretlyB. separatelyC. electronicallyD. mentally26.What makes the writer feel uncomfortable nowadays?A. Saving money is out of date.B. Spending money is so fast and easy.C. Earning money is getting more difficult.D. The pleasure of spending money is fading.27.The writer implies that_________.A. he likes the nature of his walletB. he is against technological progressC. he feels insecure about the changes of the modern paymentD. he wants to return to the old traditions of the old society.CFor many people in the US, sports are not just for fun. They’re almost a “religion”.Thousands of sports fans buy expensive tickets to watch their favorite teams and athletes play in person. Other fans watch the games at home,sticking to their TV sets,never missing a game. Many a wife becom es a “sports widow” during her husband’s favorite season. Americans’ devotion to sports has created a new class of wealthy people:professional athletes. Sports stars often receive million-dollar salaries. Some even make big money by appearing in advertisements for soft drinks,shoes and almost everything.Sports are an important part of American culture. Throughout their school life,Americans learn to play many sports. Many students try out for the school teams. Athletic events at universities attract scores of fans and benefit the whole community. Many people also enjoy non-competitive activities,like hiking,cycling,horseback riding,camping or hunting.Many sports were imported from other countries. Europeans brought tennis,golf,bowling and boxing to America. Football and baseball came from other Old World games. Only basketball has a truly American origin. Americans export sports fever as well. Satellites broadcast games to sports fans around the globe. NBA is a good example. The names of American superstars like basketball great Michael Jordan have become household words all over the world. 28.Many a wife becomes a “sports widow” in the US probably because________. A.they are serious in religion B.they are devoted to sportsC.their husbands are missing D.their husbands stick to sports29.Which of the following is NOT true according to the passage? A.American people like to exchange different sports from each other. B.American students go in for various sports and athletic events.C.Lots of American people take part in non-competitive activities.D.The US sports stars can earn a large sum of money via the media.30.We can infer from the passage that________.A.all the Americans are sports fans B.most Americans like competition C.sports culture influences the world D.America has invented many sports 31.The writer mainly intends to tell us________.A.where sports can help to make money B.how important sports are in America C.why sports are so popular in America D.what affect Americans’ everyday lifeCHave you ever run into a careless cell phone user on the street? Perhaps they were busy talking, testing or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name — phubbers (低头族).Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie(自拍照) in front of a car accident site and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.Although the ending sounds overstated, the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying. “The neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.But that’s not a ll. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happilywith each other and this creates a strange atmosphere, Qilu Evening News reported.It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.32. For what purpose does the author give the example of a cartoon in Para. 2 ?A. To inform people of the bad effects of phubbing.B. To advertise the cartoon made by students .C. To indicate the world will finally be destroyed by phubbers.D. To warn doctors against using cell phones while treating patients.33. Which of the following is NOT a risk a phubber may have?A. His social skills could be affected.B. His neck and eyesight will be gradually harmed.C. He will cause the destruction of the world.D. He might get separated from his friends and family.34. Which of the following may be the author’s attitude towards phubbing?A. Supportive.B. Opposed.C. Optimistic.D. Objective.35. What may the passage talk about next?A. Advice on how to use a cell phone.B. People addicted to phubbing.C. Measures to reduce the risks of phubbing.D. Consequences of phubbing. 第二节(共5小题;每小题2分,满分10分)Five Life Skills Your Teen Should Learn Before Moving Out ____36____ Teens should understand the importance of sleep, exercise and nutrition.

It will be great 62 you can tell me some information about chopsticks, such 63 their origin and the materials they are made from.M: Good question. Chopsticks originated in China, but they are 64 (wide) used in many Asian countries. Chopsticks may be made of any of the65 (follow) materials: bamboo, wood, gold, silver, ivory, or plastic, and they may be 66 round or square. Some chopsticks are decorated 67 colored pictures. Ordinary chopsticks used in Chinese homes are made of wood or bamboo. In ancient times, the rich used jade or gold chopsticks to display their wealth. Many kings and emperors used silver chopsticks to see if their food had been poisoned.W: OK, thank you. And I’d like to know why Chinese people use chopsticks.68 not knives and forks, like Americans?M: Oh, that is a good question. I think Chinese people choose chopsticks, rather than knives and forks, because Chinese people, under the influence of Confucianism, have traditionally 69 (consider) knives and forks as symbolizing a type of violence. On the other hand, chopsticks reflect 70 (gentle) and kindness. And maybe Chinese food simply seems to taste better when eaten with chopsticks.第三部分书面表达(满分25分)假设你是学生李华,得知好朋友William在学习中感到压力很大,学习效果甚微,请你按照以下要点给他写一封电子邮件,帮助他放松身心,提高学习效率。
