人教版高考物理一轮总复习课后习题 第一章 运动的描述 匀变速直线运动的研究 单元质检一

单元质检一运动的描述匀变速直线运动的研究(时间:90分钟满分:100分)一、单项选择题(本题共8小题,每小题3分,共24分,在每小题给出的四个选项中,只有一项符合题目要求)1.(浙江常熟高三上学期阶段性抽测)关于速度的描述,下列说法正确的是( )A.电动车限速20 km/h,指的是平均速度大小B.子弹射出枪口时的速度大小为500 m/s,指的是平均速度大小C.某运动员百米跑的成绩是10 s,则他冲刺时的速度大小一定为10 m/sD.京沪高速铁路测试时列车最高时速可达484 km/h,指的是瞬时速度大小答案:D解析:电动车限速20km/h,即最高速度不超过20km/h,是指瞬时速度,故A 错误;子弹射出枪口时的速度大小为500m/s,指的是瞬时速度,故B错误;10m/s是百米跑的平均速度,但冲刺时的速度为瞬时速度,大小不能确定,故C错误;京沪高速铁路测试时列车最高时速可达484km/h,指的是某时刻的速度可以达到484km/h,是瞬时速度,故D正确。

2.(河南名校联盟高三上学期10月质检)我国首艘海上商用地效翼船“翔州一号”,从三沙市永兴岛到三亚仅仅只需要几个小时,若地效翼船“翔州一号”到港前以6 m/s2的加速度做匀减速直线运动,其初速度为60 m/s,则它在12 s内滑行的距离是( )A.144 mB.288 mC.150 mD.300 m答案:D=解析:地效翼船从以初速度为60m/s,运动到停止所用时间t=v-v0a0-60s=10s,由此可知地效翼船在12s内不是始终做匀减速运动,它在最后-62s内是静止的,故它12s内滑行的距离为,故选项D正确。

3.(天津一中高三月考)沿直线做匀变速运动的一列火车和一辆汽车的速度分别为v1和v2,v1、v2在各个时刻的大小如表所示,从表中数据可以看出( )v2/(m·s-1) 9.8 11.0 12.2 13.4 14.6A.火车的速度变化较慢B.汽车的加速度较小C.火车的位移在减小D.汽车的速度增加得越来越慢答案:A解析:火车的加速度为a1=Δv1Δt =-0.51m/s2=-0.5m/s2,汽车的加速度为a2=Δv2Δt =1.21m/s2=1.2m/s2,汽车的加速度较大,火车的加速度较小,可知火车速度变化较慢,故A正确,B错误;因为火车的速度一直为正值,速度方向不变,则位移在增加,故C错误;因为汽车做匀加速直线运动,加速度不变,单位时间内速度增加量相同,故D错误。

唐山一中高三年级2016年12月调研考试语文命题:李双审核:赵梁丹注意事项:选择题第14题写在答题纸相应位置,其余均按对应题号填涂在客观题答题卡上。

第Ⅰ卷(阅读题共70分)一、现代文阅读(35分)(一)论述类文本阅读(9分)阅读下面的文字,完成1—3题。

根据史料记载来看,富民不仅向佃户提供土地、耕牛、种子、农具及其他生产生活资料,投入大量生产成本,而且对生产过程也非常关心。

苏洵说富民对佃户‚鞭笞驱役‛,应有言过其实者,但其所反映的富民驱使督促佃客耕种土地,并对相关生产活动进行管理,则应是租佃制下富民群体之共同行为特征。

胡宏言,‚夫客户,依主户以生,当供其役使,从其约束者也‛。

其所谓‚约束‛者,当是指富民主户对客户的日常管理。

他还列举了一些不从‚约束‛的表现,其中一条便是‚习学末作,不力耕桑之业‛。

由此可见富民对佃客的日常‚约束‛,一个重要的方面就是对其生产过程进行管理与监督。

这还可用宋代官田出租的‚监庄‛之制观照加以说明。

官府将系官之田出租给佃户,招募上三等富户充当‚监庄‛来进行监督与管理,并可影响到其秋成收入;官府根据所收秋成之多寡推赏,实质是对富民‚监庄‛之功效高低的酬奖;官府只招上三等富户充当监庄,说明富民已具备相关‚监庄‛之经验,而其经验的获得,当与他们对其私有庄田出租管理的实践密不可分。

进而言之,富民将私田出租,其监督与否及管理水平之高低,应同样会影响其收成之多寡,也就决定了富民一般会对其佃户生产进行‚监庄‛性质的管理。

实际上,富民对佃客生产过程实施的监督与管理是全面而细致的,包括收获环节也不放过,即使遭遇酷暑天气时也是如此。

正因为富民参与到生产活动的各个环节,其田‚种之常不后时,而敛之常及其熟。

故富人之稼常美,少秕而多实,久藏而不腐‛,提高了粮食产量与品质,增加了收成,与‚种之常不及时,而敛之常不待其熟‛,由此难获‚美稼‛的少地自耕者形成鲜明对比。

从佃客方面来讲,虽然取得完整的土地佃权进行经营是其根本利益之所在,但由于其贫困的经济状况,需要富民‚借贷赒给无所不至‛,甚至‚借贷种种,与夫室庐牛具之属,其费动百千计,例不取息‛。

各人有各人的境界,没有两个人的境界是完全相同的。

人所有的境界,由低到高可以分为四种:自然境界、功利境界、道德境界、天地境界。

一个人看见一棵树,但不知道那就是树,今天看见一棵树,明天又看见一棵树,看到一千天,他才知道那就是树。

此时,“树”并不是第一千零一棵树,而是树的概念。

如果他进一步了解到什么是概念,而又自觉其了解,他的精神境界就开始进入概念世界了。

有概念而且自觉其有概念,是人之所以高于其他动物者。

一只猫,它知道饿了就吃,累了就睡,看见可怕的东西就跑。

人就不然了。

人不但有概念,而且自觉其有概念。

金岳霖曾说“哲学是概念的游戏”,他用了一个似乎自我解嘲的词。

人们或许以为这句话是一个戏论,这是因为他没有把这句话同人的精神境界联系起来。

一个人所有的概念就是他的精神境界;一个人所有的概念的高低,就分别出他的精神境界的高低。

例如一个人没有宇宙这个概念,他就根本不可能有“天地境界”。

明代杨椒山就义时曾作二诗,一曰:“浩气反太虚,丹心照千古。

平生未了事,留与后人补。

”二曰:“天王自圣明,制作高千古。

平生未报恩,留作忠魂补。

”一般看来,两首诗是同等地位,但其实迥然不同。

第一首是就人与宇宙关系而言,是为天地境界中的话。

AA little old couple walked slowly into McDonald’s one cold winter evening. They were so old that they looked out of place amid the young families and young couples eating there that night. Some of the customers looked admiringly at them. You could tell what the admirers were thinking. “Look, there is a couple who has been through a lot together, probably for 60 years or more!”The little old man walked right up to the cash register, placed his order with no hesitation and then paid for their meal. The couple took a table near the back wall and started taking food off the tray. There was one hamburger, one order of French fries and one drink. The little old man unwrapped the plain hamburger and carefully cut it in half. He placed one half in front of his wife. Then he carefully counted out the French fries, divided them in two piles and neatly placed one pile in front of his wife. He took a sip of the drink, his wife took a sip and then set the cup down between them.As the man began to eat his few bites of hamburger, the crowd began to get restless. Again you could tell what they were thinking, “That poor old cou ple. All they can afford is one meal for the two of them.”As the man began to eat his French fries, one young man stood and came over to the old couple’s table. He politely offered to buy another meal for the old couple to eat. The old man replied that they were just fine. They were used to sharing everything.Then the crowd noticed that the little old lady hadn’t eaten a bite. She just sat there watching her husband eat and occasionally taking turns sipping the drink.Again the young man came over and begged them to let him buy them something to eat. This time the lady explained that, no, they were used to sharing everything together.As the little old man finished eating and was wiping his face neatly with a napkin, the young mancould stand it no longer. Again he came over to their table and offered to buy some food.After being politely refused again, he finally asked a question of the little old lady. “Ma’am, why aren’t you eating? You said that you share everything. What is it that you are waiting for?”She answered, “The teeth”.21. The underlined phrase in the first paragraph most probably means __________.A. looked helplessB. looked romanticC. looked cheerfulD. looked unsuitable22. Why did some of the customers admire them?A.

For two weeks I would try to be a loving husband and father. Totally loving. No ifs, ands or buts.The idea had come to me as I listened to a talk on my car radio. The speaker was quoting a Biblical passage about husbands and their wives. Then he went on to sa y, “Love is an act of will.A person can choose to love.” To myself, I had to admit that I had been a selfish husband. Well, for two weeks that would change.And it did. Right from the moment I kissed Evelyn at the door and said, “That new yellow sweater l ooks great on you.” “Oh, Tom, you noticed”, she said, surprised and pleased. Maybe a littlepuzzled. After the long drive, I wanted to sit and read. Evelyn suggested a walk on the beach. I started to refuse, but then I thought, “Evelyn’s been alone here wi th the kids all week and now she wants to be alone with me.” We walked on the beach while the children flew their kites.So it went. Two weeks of not calling the Wall Street firm where I am a director; a visit to the shell museum though I usually hate muse ums. Relaxed and happy, that’s how the whole vacation passed.I made a new promise to keep on remembering to choose love.There was one thing that went wrong with my experiment, however. Evelyn and I still laugh about it today. On the last night at our cottage, preparing for bed, Evelyn stared at me with the saddest expression.“What’s the matter?” I asked her.“Tom,” she said in a voice filled with distress, “I don’t?”“What do you mean?”“Well…that checkup I had several weeks ago…our doctor…did he tell yo u something about me? Tom, you’ve been so good to me…am I dying?”It took a moment for it all to be understood. Then I burst out laughing.“No, honey,” I said, wrapping her in my arms. “You’re not dying; I’m just starting to live.”25. From the story we may infer that Tom drove to the beach cottage ______.A. with his familyB. with EvelynC. aloneD. with his children26. During the two weeks on the beach, Tom showed more love to his wife because _.A. he was determined to be a good husbandB. he had made a lot of money in his Wall Street firmC. she looked lovely in her new clothesD. the doctor said his wife was seriously ill27. The author says, “There was one thing that went wrong with my experiment.” What does “one thing” refer to?A. He praised her sweater, which puzzled her.B. She insisted on visiting a museum, which he hated.C. He knew something about her illness but didn’t tell her.D. He was so good to her that she thought she must be dying.28. By saying “I’m just starting to live,” Tom means that ______.A. he is just beginning to understand the real meaning of lifeB. he is just beginning to enjoy life as a loving husbandC. he lived an unhappy life before and is now starting to changeD. he is beginning to feel regret for what he did to his wife beforeCA woman renewing her driver’s license at the County Clerk’s office was asked to state her occupation. She hesitated, uncertain how to classify herself.“What I mean is,” explained the recorder, “do you have a job, or are you just a …”“Of course I have a job,” said Emily.“I’m a mother.”“We don’t list ‘mother’ as an occupation… ‘housewife’ covers it,” said the recorder.One day I found myself in the same situation.The clerk was obviously a career woman, confident and possessed of a high sounding title.“What is your occupation?” she asked.The words simply popped out.“I’m a Research Associate in the field of Child Development and Human Relations.”The clerk paused, ballpoint pen frozen in midair.I repeated the title slowly, and then I stared with wonder as my statement was written in bold, black ink on the official questionnaire.“Might I ask,” said the clerk with new interest, “Just what you do in this field?”Coolly, without any trace of panic in my voice, I heard myself reply, “I have a continuing program of research (what mother doesn’t), in the lab and in the field (normally I would have said indoors and out). Of course, the job is one of the most demanding in the humanities (any mother care to disagree?), and I often work 14 hours a day (24 is more like it).But the job is more challenging than most careers and rewards are more of a satisfaction rather than just money.”There was an increasing note of respect in the clerk’s voice as she completed the form, stood up, and showed me out.As I drove into our driveway, buoyed up (依托) by my glamorous new career, I was greeted by my lab assistants---ages 13, 7, and 3.Upstairs I could hear our new experimental model (a 6 month old baby), in the child-development program, testing out a new vocal pattern.I felt proud! I had gone on the official records as someone more distinguished andindispensable (不可缺少的) to mankind than “just another mother.”Motherhood…What a glorious career! Especially when there’s a title on the door.29. What can we infer from the conversation between the woman and the recorder at the beginning of the passage?A. The woman felt ashamed to admit what her job was.B. The recorder was impatient and rude.C. Motherhood was not recognized and respected as a job by society.D. The author was upset about the situation that mothers faced.30. Why did the woman clerk show more respect for the author?A. Because the author cared little about rewards.B. Because she admired the author’s research work in the lab.C. Because she thought the author did admirable work.D. Because the writer did something she had little knowledge of.31. What is the author’s purpose of writing the passage?A. To show how you describe your job affects your feelings toward it.B. To show that the author had a grander job than Emily.C. To argue that motherhood is a worthy career and deserves respect.D. To show that being a mother is hard and boring work.DIt was Sunday morning. I heard loud noises of moving furniture in the next room. I could almost feel the excitement of John who was soon going to get a room of his own. I knew how much he longed for his right to privacy when he was sharing a room with his younger brother, Robot. He said, “Mum, Can I have a room of my own? I could use Jeff’s. He won’t mind.”It was true that Jeff had graduated from college and flown from the nest. But would he mind? The room was the place where I told him a thousand stories and we had a thousand talks. As close as we were, though, the time came when Jeff needed a door between us. His life was spreading into areas that had less to do with family. I no longer could-or-should know everything about him.It turned out that getting Jeff’s permission was easy. He said, “Of course, Mum, it would be selfish of me to hold on to it.” Then his voice softened, “Mum, I won’t be living at home again — you know that.” Behind his glasses, his eyes were lit with all the love. There were no doors closed here— they had all opened up again.As John and I were cleaning the room, I fixed my eyes o n Jeff’s things around me and could almost touch the little boy I knew was gone forever. I looked at the room and, in my heart, I let it go. To hold on would be, as Jeff said, selfish. Now it was time for John, shouldering through the door, his eyes bright with promise of independence, to disappear behind the door. It was time for letting go to happen again.32. The underlined sentence in the second paragraph probably means “______”.A. Jeff needed his right to privacyB. Jeff finally flew out of the houseC. Jeff got tired of those familiar storiesD. Jeff would have less to do with his family33. Which of the following is TRUE according to the passage?A. John was moving to live with his brother.B. John was eager to get a room of his own.C. Jeff volunteered to give his room to John.D. Jeff refused to let his brother have his room.34. How did the author feel about her children’s sense of independence?A. Delighted.B. Jealous.C. Mixed.D. Embarrassed.35. It can be inferred from the passage that ______.A. the children did not like to live with adultsB. all her three kids made the author feel depressedC. none of the members in the family thought the same wayD. the author loved and missed the time together with her kids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。

南阳一中2016年秋高三第三次月考语文试题命题:方云国、徐红伟、牛远、谭丽、华新旭、田济华、吴文选组题:李纳新 10.28 一、阅读下面的文字,完成1~3题。

(9分)“黑箱”是控制论中的概念,意为在认识上主体对其内部情况全然不知的对象。

“科技黑箱”的含义与此有所不同,它是一种特殊的存贮知识、运行知识的设施或过程,使用者如同面对黑箱,不必打开,也不必理解和掌握其中的知识,只需按规则操作即可得到预期的结果。

例如电脑、手机、摄像机、芯片,以及药品等,可以说,几乎技术的全部中间和最终成果都是科技黑箱。

在科技黑箱的生产过程中,科学知识是基础,价值观和伦理道德则对科学知识进行选择。

除此以外,科技黑箱中还整合了大量人文的、社会的知识,并且或多或少渗透了企业文化和理念。

这样,在电脑或手机中就集成了物理学、计算机科学、管理学、经济学、美学,以及对市场的调研和政府的相关政策等知识。

科技黑箱是特殊的传播与共享知识的媒体,具有三大特点。

首先,它使得每一个使用者——不仅牛顿,都能直接“站在巨人的肩上”继续前进。

试想,如果要全世界的电脑使用者都透彻掌握电脑的工作原理,掌握芯片上的电子理论,那需要多少时间?知识正是通过科技黑箱这一途径而达到最大限度的共享。

如今,计算机天才、黑客的年龄越来越小,神童不断出现,他们未必理解计算机的制作过程就能编写软件、破译密码。

每一代新科技黑箱的出现,就为相对“无知识”的年轻一代的崛起与赶超提供了机会。

其次,处在相对低端的科技黑箱往往与语境和主体无关,而处于高端的科技黑箱则需满足特定主体在特定场合乃至心理的需要。

人们很少能对一把锤子做什么改进,而使用一个月后的电脑则已经深深地打上了个人的印记,这就说明,在认识变得简单易行之时,实践变得复杂和重要。

最后,当科技为我们打开一扇又一扇门的时候,我们能拒绝它的诱惑不进去吗?而一旦进去,我们的行为能不受制于房间和走道的形状吗?表面上是使用者在支配科技黑箱,然而科技黑箱却正在使用者“不知情”的情况下,对使用者施加潜移默化的影响,也就是说使用者被生产方对象化了。

天津市2024高三上学期第三次月考语文试卷本试卷考试时间150分钟,总分150分。

第I卷一、(9分)阅读下面一段文字,完成下面小题。

苏州的美是含蓄的。

要是不下一番寻索的(),你就别想领会它。

________走到山腰,站在“迎笑亭”前,回头一看,原来这么美!眼下是一片松树的海,没有风,但是闭上眼睛,就能听到一种()的声音,正如悠远的琴曲。

深吸一口气,就闻到松脂()的芳香。

再远一点,有整齐的农田,有蜿蜒的小河,有模糊的远山。

传闻这条小河是为西施到对面象山而开凿的。

你怎能信任这条满怀青春的小河倒有两千岁!正如我跟前这座“迎笑亭”,一个四角方方的房子,你怎能信任这就是传闻中苏东坡到过的地方。

可是假如四周的美景把你迷得(),你是什么都会信任的,仿佛自己已经置身仙山。

1. 依次填入括号内的词语,最恰当的一组是()A. 功夫飒飒沁人心脾神魂颠倒B. 工夫铮铮神清气爽如痴如醉C. 功夫飒飒神清气爽如痴如醉D. 工夫铮铮沁人心脾神魂颠倒2. 下列填入文中横线处的句子,连接最恰当的一项是()A. 站在灵若山跟前,觉得它不过是一个有树的山丘,所以没有什么稀奇的。

B. 站在灵岩山跟前,并不觉得它有什么稀奇的,不过是一个有树的山丘罢了。

C. 灵岩山不过是一个有树的山丘罢了,站在它跟前,不觉得它有什么稀奇的。

D. 灵岩山并不让人觉得它有什么稀奇的,不过是一个有树的山丘罢了。

3. 对选文中涉及的文化常识解说正确的一项是()A. 古代的琴曲有很多,比如著名的《高山流水》,据《列子》记载,俞伯牙弹琴,钟子期能听出他是“志在高山”还是“志在流水”,遂成知音。

B. 西施是古代著名的美女,后世《红楼梦》中,曹雪芹却用“病如西子胜三分”来形容贾宝玉,别有一番趣味。

C. 苏轼的文化思想特别丰富,儒、道、释三家对其均有影响,我们从其作品中就可以感受到。

比如“人生如梦”一句,可以品出《庄子》的意味,“逝者如斯”,源自《诗经》,而“造物者之无尽藏”,则是佛家用语。
