College courses learned on line.C. Some world-famous lectures.D. Four interesting books in discount.BMatthew Layton was 20 minutes from home in Sevierville, Tennessee, on a cold November night in 2016 when he got a cell phone call from his mother. "The mountain’s on fire,” she screamed, “and Brian’s up there!”Layton’s family owned a dozen rental cabins(小屋) on Shields Mountain, and Layton’s friend and fellow rental-cabin owner, Brian McGee, age 56, was up there trying to put the fire out by himself. Layton, 32, hit the gas. He lived on the mountain too.Layton turned around and headed for a dirt road. He made it about halfway up the steep, winding path before his front-wheel-drive car gave up. He called McGee, who drove down in his pickup so they could fight the fire together.They headed first to Layton’s rental cabins. “I wanted to make sure our guests were gone. They were,” says Layton. At that point, he had a choice: try to save his cabins or resc ue people renting other cabins nearby. “On the moun tain, you don't have many locals. They’re mostly tourists who don’t know their way around,” he says.Over the next two hours, the two friends drove through the smoky mountain, knockingon doors and leadi ng panicked people to safety. “I know that mountain so well,” Layton says, “I could drive and know exactly where I am just by time traveled.” Thanks to their brave and immediate action, the two helped 14 people out of the danger.Fourteen people died that night in Sevier County. But the fire didn’t take away a single life on Shields Mountain. And though his home and business were destroyed, Layton remains calm. “I wasn’t worried about my loss, not when I saw those families trapped on the mountain,” he says,“I knew I was gonna help them.”24. Where was Layton when the fire broke out?A. Visiting his mother.B. Away from his home.C. Heading for the cabins.D. Driving on a dirt road.25. What can we learn from Para.2-3?A. Layton’s car broke down ha lfway.B. Brian was in charge of Layton’s cabins.C. Layton picked up Brian on the path.D. Brian lived in the mountain alone.26. Why could the two friends rescue the people?A. They put out the fire before it spread.B. They turned to locals for help.C. Layton was familiar with the area.D. Brian gave up his own cabins.27. What did Layton mean in the last paragraph?A. He blamed himself.B. He suffered a lot.C. He was relieved.D. He felt sorry.CIf your friends are happy—turns out you’re more likely to be happy too.If your friends are overweight, that too ups the chances you’ll gain weight. Those effects have been shown in studies. And now researchers have identified another seemingly contagious quality: exercise.The researchers analyzed the running activity of more than a million people worldwide who used an exercise tracking device(装置) for five years. And they used weather patterns as a way to randomly examine different parts of that global network.Cities have different weather patterns, Sinan Aral, a computational social scientist at MIT says, this experiment allowed them to ask: Does a rainy day in New York affect running in San Diego? “If the weather in New York causes changes in the running behavior in San Diego, it can really only be happening through the influences of the friends who live between New York and San Diego.”And that is exactly what he and his colleague saw: that the behavior of one city’s runners could indeed affect the behavior of runners in another socially connected city. Women tended to be influenced more by the female runners in their networks. And less active runners tended to influence more active runners to run more, but not so much the other way around.Still, this could be valuable for health professionals. “We have to start thinking about consumers and citizens as networked consumers and citizens. Where they are influenced by and influence their social network in very strong ways, that will change the way a particular intervention(干涉) succeeds or fails.”In other words—if your prescription is more exercise? The doctors might want to write a prescription for your friends and family, too.28. Which does the underlined word “contagious” in Para. 1 mean?A. Affected.B. Excellent.C. Beneficial.D. Different.29. What can we conclude from the experiment?A. Weather changes people’s feelings.B. People’s behaviour affects each other.C. Exercise has something to do with weather.D. P eople’s connection depends on distance.30. What does “this” in Para. 5 refer to?A. Women are easier influenced by male runners.B. People in the same city affect each other more.C. Friends tend to influence each other in exercising.D. A rainy day in one city affects running in another.31. Which of the following can be the best title for the text?A. Think twice before running.B. More exercise benefits health.C. Weather patterns affect running behavior.D. Healthy behavior can spread like illness.DMany Americans think of driverless cars as a futuristic technology that will revolutionize travel in cities and along state highways. But recent experiments are proving that autonomous vehicles also have the potential to improve the quality of life for millions of Americans underserved by traditional modes of transportation, such as the elderly and disabled, so long as lawmakers make smart policies that pave the way for innovation.A retirement community in San Jose, Calif. , which has been transformed by a small fleet of driverless taxis, shows the potential of self-driving cars to transform people’s lives. Built by a tech start-up called Voyage, the modified Ford Fusions are currently limited to a two-mile road, but residents are already having the benefits of these autonomous vehicles, which allow them to participate in social activities they would otherwise be unable to enjoy simply because they could not get to them.When the trial run finally expands to 15 miles of road, these residents—whose average age is 76—will also have a convenient and reliable new way to appointments. As these cars continue to serve residents there, it is easy to understand why California is moving to simplify regulations for the industry.In Michigan, forward-thinking policies have the potential to unlock other hidden benefits of autonomous vehicles, especially for those with physical disabilities. The Michigan Disability Rights Coalition has strongly advocated for the development of this technology, saying that it could give people with disabilities greater opportunities in the workforce and enable them to lead more fulfilling, independentlives.Many recognize that autonomous vehicles will be the future of transportation, but it is too often overlooked that this future cannot arrive fast enough for millions of Americans who are forced to depend on others for day-to-day travel. The policymakers should follow the lead of places like California and Michigan, and pass rules and regulations to unlock these hidden benefits of driverless cars.32. Wha t’s the attitude of most American people to the future of autonomous vehicles?A. Curious.B. Doubtful.C. Indifferent.D. Optimistic.33. What is the modified Ford Fusion?A. A kind of autonomous vehicle.B. A fleet of driverless taxis.C. A road for driverless cars.D. A retirement community.34. What are examples in California and Michigan to prove?A. Driverless cars’ disadvantages.B. Governments’ right decisions.C. Benefits to the aged and the disabled.D. The regulations are forward-thinking.35. What does the author attempt to inform us in the last paragraph?A. The benefits of driverless cars have been fully unlocked.B. Regulations should go hand in hand with driverless technology.C. The concept of autonomous vehicles has been widely recognized.D. The weak groups are often overlooked despite technology advances.阅读附加题:Cities usually have a good reason for being where they are, like a nearby port or river. People settle in these places because they are easy to get to and naturally suited to communications and trade. New York City, for example, is near a large harbour at the mouth of the Hudson River. Over 300 years its population grew gradually from 800 people to 8 million. But not all cities develop slowly over a long period of time. Boom towns grow from nothing almost overnight. In 1896, Dawson, Canada, was unmapped wilderness (荒野). But gold was discovered there in 1897, and two years later, it was one of the largest cities in the West, with a population of 30,000.Dawson did not have any of the natural conveniences of cities like London or Paris. People went there for gold. They travelled over snow-covered mountains and sailed hundreds of miles up icy rivers. The path to Dawson was covered with thirty feet of wet snow that could fall without warning. An avalanche (雪崩) once closed the path, killing 63 people. For many who made it to Dawson, however, the rewards were worth the difficult trip. Of the first 20,000 people who dug for gold, 4,000 got rich. About 100 of these stayed rich men for the rest of their lives.But no matter how rich they were, Dawson was never comfortable. Necessities like food and wood were very expensive. But soon, the gold that Dawson depended on had all been found. The city was crowded with disappointed people with no interest in settling down, and when they heard there were new gold discoveries in Alaska, they left Dawson City as quickly as they had come. Today, people still come and go — to see where the Canadian gold rush happened. Tourism is now the chief industry of Dawson City — its present population is 762.1. What attracted the early settlers to New York City?A. Its business culture.B. Its small population.C. Its geographical position.D. Its favourable climate.2. What do we know about those who first dug for gold in Dawson?A. Two-thirds of them stayed there.B. One out of five people got rich.C. Almost everyone gave up.D. Half of them died.3. What was the main reason for many people to leave Dawson?A. They found the city too crowded.B. They wanted to try their luck elsewhere.C. They were unable to stand the winter.D. They were short of food.4. What is the text mainly about?A. The rise and fall of a city.B. The gold rush in Canada.C. Journeys into the wilderness.D. Tourism in Dawson.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。

中国香文化是中国独具特色的传统文化之一。

它的起源甚早,据考古学家的考证,甚至可以追溯到石器时代。

距今6000多年前的新石器晚期,古人就以燃烧木柴和其他祭品的方式来祭祀天地诸神。

近几十年考古发现的各类文物(如陶熏炉)表明,早在四五千年前,古人就已经使用香品了。

作为活化石的殷商甲骨文,早在3000多年前就已经有了“柴”字,意为“手持燃烧的祭礼”,堪称祭祀用香的形象注解。

春秋战国时,由于地域所限,中土气候温凉,不太适宜香料植物的生长,所用香木香草的种类尚不如后世丰富,但关于香木香草的使用方法已有很多,有熏烧(如蕙草、艾蒿),佩带(香囊、香花香草)、煮汤(泽兰)、熬膏(兰膏)、入酒等方法。

在我国第一部诗歌总集《诗经》中,不乏记述采掇香药香草的歌谣,如“彼采萧兮,一日不见,如三秋兮。

彼采艾兮,一日不见,如三岁兮”。

我国第一部医学典籍《黄帝内经》,总结了我国人民与疾病长期斗争的医疗经验,其中就提出了艾灸、熏燎等治病方法。

人们对香木香草不仅取之用之,而且歌之咏之,托之寓之。

《尚书》有“至治馨香,感于神明”之语,《孔子家语﹒六本》说:“入芝兰之室,久而不闻其香。

”在伟大诗人屈原的《离骚》、《九歌》等名篇中,他用香草来歌颂忠贤,以莸草来痛斥奸邪,我们可以从中了解战国时期香文化的一些梗概。

秦汉时期,封建社会的巩固,华夏大地的大统一,特别是汉朝张骞通西域后,丝绸之路的开通,使中外文化出现了空前的大交融。

当时东南亚、南亚和欧洲等地的各种香料开始传入我国,丰富了我国的香料种类,推动了香文化的发展。

班固给其弟班超的书信中有“窦侍中令载杂丝七百尺,市月氏马、苏合香”等语句,可见当时香料是丝绸之路中外贸易的主要商品之一。

《汉官曲制》还规定,“尚书郎怀香握兰,趋走丹墀”,“含鸡舌香伏奏事”。

I found an ad for selling greeting cards in the back of a children’s magazine. I thought to myself I could do this. I begged my mother to let me send for the kit (成套工具).Two weeks later the kit arrived. The next three hours later, I returned home withno card and a pocket full ofmoney shouting, “Mama, all the people couldn’t wait to buy my cards!” A salesperson was born.When I was twelve years old, my father took me to see Zig Ziegler. I remember sitting in the dark hall listening to Mr. Ziegler raise everyone’s spirits up to ceiling. I left there feeling like I could do anything. When we got to the car, I turned to my father and said, “Dad, I want to make people feel like that.” My father asked me what I meant. “I want to be a motivational speaker just like Mr. Ziegler,”I replied. A dream was born.Recently, I began pursuing my dream of motivating others. I realized that everything I had accomplished —the graduate degree, the successful sales career, speaking appointments, training and managing for a major fortune100 company as a senior manager— had prepared me for this moment. I told my boss who was a great leader I would leave the company though I might not reach such a height in career. He told me to proceed and he believed I would succeed.Having made that decision, I was immediately tested. One week after I gave notice, my husband was laid offfrom his job. We had recently bought a new home and needed both incomes to make the monthly mortgage (抵押) payment and now we were done to no income. I even planned to turn back to my former company, knowing they wanted me to stay but I was certain that if I went back, I would never leave. I decided I still wanted to move forward rather than end up with a mouth full of “if onlys” later on. A motivational speaker was born.When I held fast to my dream, even during the tough times, the miracles(奇迹)really began to happen. In ashort time period my husband found a better job. We didn’t miss a mortgage payment. And I was able to book several speaking appointments with new clients (客户). I discovered the incredible power of dreams. I loved my old job, my workmates and the company I left, but it was time to get on with my dream. To celebrate my success I had a local artist paint my new office as a garden. At the top of one wall she marked, “The world always makes way for the dreamer.”24.Why was the kit sent for?A. Selling greeting cards.B. Collecting greeting cards.C. Buying greeting cards.D. Sending greeting cards.25.When did the author decide to become a motivational speaker?A. After buying a new home by mortgage.B. After giving notice to leave her secure position in the company.C.

Everyone will find their dreams.CLong before iphones, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.Of course, technology does not yellow your teeth, cause disease or lead to cancer.But some individuals are soconcerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colors on their screens to a less tempting scale of gray.The big tech companies will have to work out how to respond to this new generation of quitters. Facebook isthe first to go public with its attempt, hoping its recent move can make the social network more homely.Last year the tech industry got a bad name—Big Tech—with unfortunate echoes(共鸣) of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders(股东) that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money in tobacco stocks.It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in theworld—connecting old friends and giving space for people to share their ideas—from the bad. In the meantime, stopping using technology remains problematic. In The W orld W ithout Mind: The Existential Threat of Big T ech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.So we need to do more to turn the tide. In the same way that public service announcements made smokingaround your children taboo(禁忌),we can warn parents against losing themselves in their smartphones while taking care of kids.We can also create no-smartphone zones at dinner. Eventually smartphones could be banned from all public places and help us give our attention to the people around us instead.28.How did people keep close relationships with others in the past?A. By smoking.B. By drinking.C. By phoningD. By diningout.29.Why is the tech industry called Big Tech?A. It plays a bad role in the world.B. It is as big as Big Tobacco.C. It has an unfortunate name.D. It is a giant in Silicon Valley.30.What can we infer from Franklin Foer’s argument about the tech?A. It promotes social development.B. It is still favored by some people.C. It is worse than Big Tobacco.D. It offers continuing nutrition.31.Which can be the best title for the passage?A. Creating a No Smartphone LifeB. Smartphones Enrich Our Social LifeC. Smoking Does Greater Harm Than Smartphones DoD. Quitting Smartphones Is the New Quitting SmokingDComedy and PsychologyEarlier this year I did a part-time comedy course. The class was taught by Ryan,a professional comedian.Ihad performed a show, which wasn’t originally meant to be a comedy. However, the audience laughed at my first joke, then continued to laugh throughout the routines that were meant to be serious. So it was the audience who told me I was funny, but I didn’ t understand why or how to control the comic (滑稽的) moments. So, I joined the course to learn.“Turn off your editor that makes you say the right thing and remember how to be a child,” explained Ryan. “Don’t try to be clever. Don’t try too hard to be funny…and knowing all about the theory of humor is unlikely to help you much. Just behave in a silly way. That’s what people want to see on stage.” Ryan would help us loosen up by saying things like, “Wander around talking to others, but make sure that you’re the lowest status person here.”I’d say that understanding the psychology of humor has actually helped. RecentlyI came across the bookInside Jokes: Using Humor to Reverse-Engineer the Mind. Its main idea is that any self-directed intelligent system will need to correct its own fault. There’s a risk that the occasional error will be made. If this was boring or burdensome, we’d be less willing to do it. However, evolution has made the process fun.Here’s a joke in the book: Two fish are in a tank. One says to the other, “Do you know how to drive thisthing?” It works on the principle that we have started to imagine one thing—that the tank is the typical container people keep fish in—and, just in time, the following words tell us that our first assumption was wrong—it’s a heavy vehicle. For correctlyfiguring out the error, we are rewarded with a pleasurable feeling. The joke is an efficient way of encouraging this natural reaction, and comedians have become experts in slightly touching this mental funny-bone in order to make us laugh.Ryan was right when he said that knowing the theory of humor wouldn’t help us that much as acomedy.During one exercise in the course, four of us were told to perform an opera. Susan and Caroline sang earnestly on either side of the stage, and I brought Henry to the floor, where we wrestled (摔跤) each other likeout-of-control teenagers. The rest of the group was in uncontrollable fits of laughter. As a performer, I’ ll neverappreciate just why it seemed so funny. But the point is that I would never have written this on the paper. It was a joyous, found moment.32.Why did the author attend the comedy course?A. He wanted to see how the theories worked in practice.B. He discovered he had some natural ability in comedy.C. He worried about how other performers would find him.D. He got unpleasant experiences when performing a comedy.33.Ryan required the people on the comedy course to .A. copy their favorite performanceB. imagine other people’ s reactionsC. help themselves feel comfortableD. behave in a more playful manner34.What is the purpose of the joke mentioned in Paragraph 4?A. To discuss what humor brings about exactly.B. To give an example of another kind of humor.C. To prove the point about psychology of humor.D. To show why some people are funnier than others.35.What view does the author put forward in the end?A. Visual humor is what appeals to people most.B. What people find funny is often unpredictable.C. Theories explaining humor tend to be mistaken.D. Learning comic skills proves to be a difficult task.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。

河南省镇平县第一高级中学2017-2018学年高一上学期期末考前诊断语文试题

【题文】作文。

请以“回眸”为题写一篇不少于800字的记叙文。

要求:①文体必须是记叙文;②不要套作,不得抄袭。

【答案】回眸余余落辉,我爱一抹最美;涓涓潺水,我掬一捧最清;回顾走过的树林,我独恋枫叶最红;回眸成长的足迹——-我不忘毅者无疆的坚强。

7岁时,我爱看《西游记》,而孙悟空便是我的信念。

纵然可以千变万化,也要忍受五指山下的嘲讽,一压就是五百年,一忍就是风吹雨打,谁能顶天立地,坚强,被一只猴神化得如此悲壮,这便是开始,即便寂寞也精彩,大丈夫能屈能伸,猴哥,就应该这样。

10岁时,我迷上《三国演义》,原先只是喜欢打打杀杀,敬佩关羽而怨恨曹操,那一夜,考试失利后难眠的一夜,心头一触,原来曹操才是英雄。

这位大将军在宛城丧子折兵后的痛定思痛;这位汉丞相败走华容道时的嘲笑诸葛亮、周瑜;这位魏王在割须弃泡后巧施反间计,连遭挫折到始终不忘统一天下的抱负,不像刘备,被火烧七百里联营,烧回白帝城后一病不起;不像孙权,夺会荆州,守者父兄的基业就面南称帝。

曹操把坚强演义到顶峰,“老骥伏枥,志在千里;烈士暮年,壮心不已”,曹公的诗好不令人痛快!那一夜,我醒了,困难打不败,挫折打不倒,我学会了坚强。

13岁,我张大了,渐渐孤傲了,但《名人传》却逆转了我,他们都有伟大的成就,而他们也都是磨难造就的人,他们在漫漫黑夜中摸索前进,而坚强是他们心中的航标,即使看不到光明,他们却将坚强表现得淋漓尽致。

贝多芬在双目失明后继续创作乐曲,坚强是他音乐的音符;米开朗琪罗在教堂中,即使心不情愿,也全神贯注的雕刻,坚强是他的灵感,直到生命最后仍在坚持。

我心中孤傲的火焰慢慢熄灭,化作一泓平静泉水。

今年我15岁了,回眸成长之间,我懂了一句话“天将降大任于是人也,必先苦其心志,劳其筋骨,饿其体肤,空乏其身,行拂乱其所为”,既然上天已降大任于你我,那么,就让我们带者坚强出发吧!去奋斗,去拼搏,去履行生命的诺言!【解析】试题分析:这是一篇命题作文。

写作要求:以“回眸”为题写一篇不少于800字的记叙文①文体必须是记叙文;②不要套作,不得抄袭。

河南省镇平县第一高级中学2017—2018学年高一上学期期末测试数学试题第Ⅰ卷(共60分)一、选择题:本大题共12个小题,每小题5分,共60分.在每小题给出的四个选项中,只有一项是符合题目要求的.1. 设A=x,y y=−4x+6,B=x,y y=5x−3,则A∩B等于()A. 1,2B. 1,2C. x=1,y=2D. 1,2【答案】B【解析】A=x,y y=−4x+6,B=x,y y=5x−3,两个集合均为点集,所以交集为直线的交点组成的集合.由y=−4x+6y=5x−3,解得x=1y=2,所以A∩B=1,2.故选B.2. 如果a>1,b<−1,那么函数f x=a x+b的图象在()A. 第一、二、三象限B. 第一、三、四象限C. 第二、三、四象限D. 第一、二、四象限【答案】B【解析】∴y=a x的图象过第一、第二象限,且是单调增函数,经过(0,1),f x=a x+b的图象可看成把y=a x的图象向下平移−b(−b>1)个单位得到的,故函数f x=a x+b的图象经过第一、第三、第四象限,不经过第二象限,故选B.3. 设A=x1<x<2,B=x x<a,若,则的取值范围是()A. a≥2B. a≤1C. a≥1D. a≤2【答案】A【解析】因为A=x1<x<2,B=x x<a,且,则a≥2.故选A.4. 设f log2x=2x x>0,则f3的值是()A. 128B. 256C. 512D. 8【答案】B【解析】设log2x=t,则x=2t,所以f(t)=22t,则f2=223=28=256,故选B.5. 已知函数y=f2x的定义域是−1,1,则函数y=f log2x的定义域是()A. 0,+∞ B. 0,1 C. 1,2 D. 2,4【答案】D【解析】函数y=f2x的定义域是−1,1,所以x∈−1,1,2x∈[12,2],所以函数y=f log2x中有:log2x∈[12,2],解得x∈2,4.即函数y=f log2x的定义域是2,4.故选D.点睛:复合函数定义域的求法①若y=f x的定义域为a,b,则不等式a<g x<b的解集即为函数y=f g x的定义域;②若y=f g x的定义域为a,b,则函数g x在a,b上的的值域即为函数y=f x的定义域.6. 若函数y=f x的值域是12,3,则函数F x=f x+1f x的值域是()A. 12,3 B. 2,103C. 52,103D. 3,103【答案】B【解析】令t=f x,则t∈12,3,则y =t +1t ,易知y =t +1t 在(0,1)单调递减,在(1,+∞)单调递增. 所以当t ∈ 12,3 时, t =1时,y 有最小值为2当t =12时,y =52,当t =3时,y =103. 则函数F x =f x +1f x 的值域是 2,103 . 故选项为B.7. 已知幂函数f x =x a 的图像过点 14,12 ,则式子4a 的值为( )A. 1B. 2C. 12D. 14【答案】B【解析】幂函数f x =x a 的图像过点 14,12 ,所以(14)a =12,所以a =12.即f x =x 12. 所以4a =412=2. 故选B.8. 定义在R 上的函数f x 满足f x +y =f x +f y +2x y x ,y ∈R ,f 1 =2,则f −3 等于( ) A. 2 B. 3 C. 6 D. 9 【答案】C【解析】定义在R 上的函数f x 满足f x +y =f x +f y +2x y x ,y ∈R 令x =y =0,得f 0 =f 0 +f 0 +0,解得f 0 =0; 令x =1,y =−1得f 0 =f 1 +f −1 −2,解得f −1 =0; 令x =y =−1得f −2 =f −1 +f −1 +2,解得f −2 =2; 令x =−2,y =−1得f −3 =f −2 +f −1 +4,解得f −3 =6. 故选C.S9. 设a >1,且m =log a a 2+1 ,n =log a a −1 ,p =log a 2a ,则m ,n ,p 的大小关系为( ) A. n >m >p B. m >p >n C. m >n >p D. p >m >n 【答案】B【解析】当a >1时,易知a 2+1>2a ,再由以a 为底对数函数在定义域上单调递增,从而可知m >p又∵(a2+1)−(a−1)=a2−a+2恒大于0(二次项系数大于0,根的判别式小于0,函数值恒大于0),即a2+1>a−1,再由以a为底对数函数在定义域上单调递增,从而可知m>n又∵当a>1时2a显然大于a−1,同上,可知p>n.综上∴m>p>n.故选B.10. 定义运算a∗b,a∗b=a a≤b,b a>b,例如1∗2=1,则函数y=1∗2x的值域为()A. 0,1B. −∞,1C. 1,+∞D. 0,1【答案】D【解析】当1⩽2x时,即x⩾0时,函数y=1∗2x=1当1>2x时,即x<0时,函数y=1∗2x=2x∴f(x)=1,x⩾0 2x2x,x<0故选D.11. 某种细胞在生长过程中,每10分钟分裂一次(由一个分裂为两个),经过2小时后,此细胞可由一个繁殖成()A. 511个B. 512个C. 211个D. 212个【答案】D【解析】依题意,10分钟后,个数为21个,20分钟后,个数为22个,所以2小时后,即为120分钟后,个数应为212个.故选D.12. 方程x2+2x+1=1x()A. 无实根B. 有异号两根C. 仅有一负根D. 仅有一正根【答案】D【解析】在同一直角坐标系下画出两函数图象,如图所示:函数y=x2+2x+1和y=1x ,仅有一个交点,在第一象限,即方程x2+2x+1=1x仅有一正根.故选D.点睛:函数零点的求解与判断(1)直接求零点:令f(x)=0,如果能求出解,则有几个解就有几个零点.(2)零点存在性定理:利用定理不仅要函数在区间[a,b]上是连续不断的曲线,且f(a)·f(b)<0,还必须结合函数的图象与性质(如单调性、奇偶性)才能确定函数有多少个零点.(3)利用图象交点的个数:将函数变形为两个函数的差,画两个函数的图象,看其交点的横坐标有几个不同的值,就有几个不同的零点.第Ⅱ卷(共90分)二、填空题(每题5分,满分20分,将答案填在答题纸上)13. 函数y=log x−13−x的定义域是__________.【答案】1,2∪2,3【解析】要使函数y=log x−13−x有意义,则x−1>0x−1≠13−x>0,解得1<x<3,且x≠2.所以函数y=log x−13−x的定义域是1,2∪2,3.答案为;1,2∪2,3.点睛:常见基本初等函数定义域的基本要求(1)分式函数中分母不等于零.(2)偶次根式函数的被开方式大于或等于0.(3)一次函数、二次函数的定义域均为R.(4)y=x0的定义域是{x|x≠0}.(5)y=a x(a>0且a≠1),y=sin x,y=cos x的定义域均为R.(6)y=log a x(a>0且a≠1)的定义域为(0,+∞).x2−5x−6的递减区间是__________.14. 函数y=log12【答案】6,+∞x2−5x−6中,有x2−5x−6>0,解得x<−1或x>6.【解析】函数y=log12t为减函数,令t=x2−5x−6,则y=log12,又t=x2−5x−6,为开口向上的抛物线,对称轴为x=52所以在−∞,−1,t=x2−5x−6单调递减,在6,+∞,t=x2−5x−6单调递增,x2−5x−6的递减区间是6,+∞.由复合函数单调性“同增异减”的原则,知,函数y=log12答案为:6,+∞.15. 用二分法求函数y=f x在区间2,4上的近似解,验证f2f4<0,给定精度为0.1,需将区间等分__________次.【答案】5【解析】因为区间2,4的长度为2,所以第一次等分后区间长度为1,第二次等分后区间长度为0.5,……第四次等分后区间长度为0.125<0.2,第五次等分区间后区间长度为0.0625<0.1,所以需要将区间等分5次. 故答案为:5.16. 已知函数f x满足:(1)对任意x1<x2,都有f x1<f x2;(2)f x1+x2=f x1⋅f x2.写出一个同时满足这些条件的函数解析式__________.【答案】y=2x【解析】∵x1<x2时,f x1<f x2∴f (x )为增函数∵f x 1+x 2 =f x 1 ⋅f x 2 根据指数函数的性质,∴满足条件的函数可以是:y =a x(a >1)故答案为:y =2x (底数大于1的指数函数即可).三、解答题 (本大题共6小题,共70分.解答应写出文字说明、证明过程或演算步骤.)17. (1)求值:lg 2lg 50+lg 5lg 20−lg 100lg 5lg 2; (2)已知log 53=a ,log 54=b ,用a ,b 表示log 2512. 【答案】(1)1;(2)a +b 2.【解析】试题分析:(1)都化为与lg2有关的式子,log 34利用换底公式化为常用对数,求解即可.注意lg2lg5≠1. (2)利用换底公式将log 2512化为以5为底的对数,再将真数用4和6表达求解即可. 试题解析:(1)原式=lg 2 lg 25×2 +lg 5lg 4×5 −2lg 5lg 2=lg 2 2lg 5+lg 2 +lg 5 2lg 2+lg 5 −2lg 5lg 2 =2lg 2lg 5+ lg 2 2+2lg 2lg 5+ lg 5 2−2lg 5lg 2= lg 2+lg 5 2= lg 10 2=1(2)log 2512=log 512log 525=log 53+log 54log 552=a +b 2.18. 已知f x 是定义在 −2,2 上的减函数,并且f m −1 −f 1−2m >0,求实数m 的取值范围. 【答案】m ∈ −12,23 .【解析】试题分析:由题设条件知,可先将不等式f (m-1)-f (1-2m )>0可变为f (m-1)>f (1-2m ),再利用函数是减函数的性质将此抽象不等式转化为关于m 的不等式组,解不等式组即可得到m 的取值范围. 试题解析:由f m −1 −f 1−2m >0可得f m −1 >f 1−2m . 又f x 是定义在 −2,2 上的减函数,∴ m −1<1−2m ,−2<m −1<2,−2<1−2m <2 ⇒ m <23,−1<m <3,−12<m <32,⇒−12<m <23,即m∈ −12,23.点睛:本题属于对函数单调性应用的考察,若函数f x在区间上单调递增,则x1,x2∈D,且f x1>f x2时,有x1>x2,事实上,若x1≤x2,则f x1≤f x2,这与f x1>f x2矛盾,类似地,若f x在区间上单调递减,则当x1,x2∈D,且f x1>f x2时有x1<x2;据此可以解不等式,由函数值的大小,根据单调性就可以得自变量的大小关系.本题中可以利用对称性数形结合即可.19. 设函数y=f x(x∈R且x≠0)对定义域内任意的x1,x2,恒有f x1⋅x2=f x1+f x2. (1)求证:f1=f−1=0;(2)求证:y=f x是偶函数;(3)若f x为0,+∞上的增函数,解不等式f x+f x−12≤0.【答案】(1)见解析;(2)见解析;(3){x|1−174≤x<0或12<x≤1+174}.【解析】试题分析:(1)利用赋值法求解,令x1,x2=1或x1,x2=-1即可得证.(2)令x2=-x,x1=-1,结合奇偶性的定义即可判断.(3)利用y=f(x)在(0,+∞)上为增函数,f(1)=0,f(x)为偶函数;即可求解不等式;试题解析:(1)∵x≠0,f x1⋅x2=f x1+f x2,令x1=x2=1,f1=2f1,∴f1=0,令x1=x2=−1,f−1=2f−1,∴f−1=0.(2)∵x∈R且x≠0,恒有f x1⋅x2=f x1+f x2,令x1=−1,x2=x,∴f−1⋅x=f−1+f x,∴f−x=f x,∴y=f x是偶函数.(3)∵f x在0,+∞上为增函数,则在−∞,0上是减函数,又f x+f x−12≤0,∴f x x−12≤f1或f x x−12≤f−1,∴0<x x−12≤1,①或0>x x−12≥−1,②∴由①②得:1−4≤x<0或12<x≤1+4.点睛:本题属于对函数单调性应用的考察,若函数f x在区间上单调递增,则x1,x2∈D,且f x1>f x2时,有x1>x2,事实上,若x1≤x2,则f x1≤f x2,这与f x1>f x2矛盾,类似地,若f x在区间上单调递减,则当x1,x2∈D,且f x1>f x2时有x1<x2;据此可以解不等式,由函数值的大小,根据单调性就可以得自变量的大小关系.本题中可以利用对称性数形结合即可.20. 已知函数f x=a−22x+1a∈R.(1)判断f x在定义域上的单调性;(2)要使f x≥0恒成立,求实数的取值范围.【答案】(1)见解析;(2)2,+∞.【解析】试题分析:(1)根据单调性的定义即可判断f(x)在定义域上的单调性;(2)利用参数分离法,结合指数函数的性质进行求解.试题解析:(1)显然对任意x∈R且2x+1≠0,∴f x的定义域为R.设x1,x2∈R,且x1<x2,则f x2−f x1=a−22x2+1−a+22x1+1=22x1+1−22x2+1=22x2−2x12x1+12x2+1.∵y=2x为增函数,且x2>x1,∴2x2>2x1.而2x1+12x2+1>0恒成立,于是f x2−f x1>0,即f x2>f x1,故f x是R上的增函数.(2)由f x≥0恒成立,可得a≥22x+1恒成立.∵对任意的x∈R,2x>0,∴2x+1>1,∴0<12x+1<1,∴0<22x+1<2.要使a≥22x+1恒成立,只需a≥2即可,即的取值范围是2,+∞.21. 如过函数f x对于定义域内的任意两个数x1,x2都满足:f x1+x22≤12f x1+f x2,那么称函数f x 为下凸函数;而总有fx 1+x 22≥12 f x 1 +f x 2 时,那么称函数f x 为上凸函数.根据以上定义,判断指数函数f x =a x (a >0且a ≠1)在R 上是否为下凸函数,并说明理由. 【答案】见解析.【解析】试题分析:根据凹函数的定义,结合指数函数的图象和性质,用作差法比较大小,可得结论. 试题解析: 因为fx 2+x 22=ax 2+x 22=ax 12⋅a x 22,12f x 1 +f x 2 =12a x 1+a x 2 ,所以fx 2+x 22−12 f x 1 +f x 2 =−12 a x 1+a x 2−2ax 12a x 22=−12 a x 12−a x 222≤0,所以fx 2+x 22≤12 f x 1 +f x 2 对于R 上的任意两个数恒成立,所以指数函数在R 上为下凸函数22. 定义在R 上的函数f x 满足f x +2 =f x ,且f −x =−f x .当x ∈ 0,1 时,f x =2x 4x +1.(1)求f x 在 −1,1 上的解析式; (2)证明f x 在 0,1 上是减函数;(3)当取何值时,方程f x =λ在 −1,1 上有解.【答案】(1)f x =2x4x +1,x ∈ 0,1 ,−2x 4x +1,x ∈ −1,0 ,0,x ∈ −1,0,1 .;(2)见解析;(3)−12<λ<−25,或λ=0,或25<λ<12. 【解析】试题分析:(1)设x ∈ −1,0 ,则−x ∈ 0,1 结合f (-x )=-f (x ),及x ∈(0,1)时,f x =2x4x +1,,可求x ∈(-1,0)时得f (x ),在f (-x )=-f (x )中可求f (0)=0 (2)利用函数的单调性的定义证明即可.(3)方程f x =λ在 −1,1 上有解的充要条件是,在函数f x ,x ∈ −1,1 的值域内取值,只需求出函数的值域,然后求解k 的范围. 试题解析:(1)设x ∈ −1,0 ,则−x ∈ 0,1 . ∵f −x =−f x ,且x ∈ 0,1 时,f x =2x 4x +1,∴x ∈ −1,0 时,有f x =−f −x =−2−x4−x +1=−2x1+4x .在f−x=−f x中,令x=0得f−0=−f0⇒f0=0.∵f x+2=f x,f−x=−f x,令x=−1,得f−1+2=f−1,f−1=−f1,∴f1=−f1⇒f1=0,从而f−1=0,∴当x∈−1,1时,有f x=2x4x+1,x∈0,1,−2x4x+1,x∈−1,0, 0,x∈−1,0,1..(2)设0<x1<x2<1,则x2−x1>0,f x2−f x1=2x24x2+1−2x14x1+1=2x1−2x22x1+x2−14x1+14x2+1.∵0<x1<x2<1,∴0<x1+x2<2,∴2x1+x2>1,且2x2>2x1,∴2x1+x2−1>0,2x1−2x2<0.又∵4x1+1>1>0,4x2+1>1>0,∴2x1−2x22x1+x2−14x1+14x2+1<0,即f x2−f x1<0,∴f x在0,1上是减函数.(3)方程f x=λ在−1,1上有解的充要条件是,在函数f x,x∈−1,1的值域内取值.∵x∈0,1时,f x=2x4x+1是减函数,∴x∈0,1时,f0>f x>f1,即f x∈25,12.∵f−x=−f x,∴x∈−1,0时,f x∈ −12,−25.又f−1=f0=f1=0,∴x∈−1,1时,函数f x的值域为 −12,−25∪0∪25,12.∴当−12<λ<−25,或λ=0,或25<λ<12时,方程f x=λ在−1,1上有解.。

2017秋期期末高一考前诊断语文试题1. 下列词语中加点的字,读音有错误的一组是()A. 赎.罪(shú)驯.顺(xùn)潭柘.寺(zhâ)蓊.蓊郁郁(wěng)B. 商榷.(quâ) 枷.锁(jiā) 吐蕃.族(bō) 含情脉脉.(mò)C. 砥砺.(lì) 蜷.缩(juǎn) 应.声虫(yìng) 放浪形骸.(hã)D. 惦.记(diàn)袅娜.(nuó)普陀.山(tuó) 游目骋.怀(chěn g)【答案】C【解析】试题分析:题干是“下列词语中加点的字,读音有错误的一组是”。

本题考查汉字字音的识记和辨析。

要看准题目要求,是选择“有错误”的一项。

C项,蜷.缩(quán )放浪形骸.(hái)点睛:高考字音考查的对象主要有多音字、形声字和异形(包括形似)同音(包括近音)字三种。

由于生活中那些容易读错的字往往也就是高考字音考查的重点内容,因此,归纳出误读的常见类型对我们复习备考是很有帮助的。

同时。

针对每一种误读类型,我们都要采取积极的措施,从而能够有的放矢地掌握好字音这个考点。

字音的误读的原因主要有以下几种。

(1)把多音字的甲音误读成乙音。

【历史】河南省镇平县第一高级中学2017-2018学年高一上学期第一次月考试题 (解析版)

河南省镇平县第一高级中学2017-2018学年高一上学期第一次月考试题一、选择题(本大题共40小题,每小题1.5分,共60分,在每小题所给出的四个选项中,只有一项是符合题目要求的)1.商代统治者凡政治事务都要通过占卜进行决策,这说明我国古代早期政治制度的特点之一是A. 神权与王权结合B. 以血缘关系为纽带C. 权力的高度集中D. 以宗族关系为基础【答案】A【解析】根据题干可知,商朝通过占卜决定国家各项事务,说明统治者欲通过神化王权加强统治,维护王权的绝对权威,A项正确。

以血缘关系为纽带维系政治统治主要涉及到西周时期宗法制,与占卜无关,排除B。

商朝实行内外服制度,商王对参加联盟的附属国的控制力是有限的,并未实现权力的高度集中,排除C。

原始社会氏族成员共同管理的形式是以以宗族关系为基础,与迷信占卜有本质区别,排除D。

综上所述,本题正确答案为A。

2.王位世袭制代替禅让制是历史的进步,主要是因为王位世袭制A. 代表了先进阶级的利益B. 是文明时代开始的标志C. 是生产力发展的结果和进步的要求D. 是华夏族开始形成的标志【答案】C【解析】随着生产力的发展,原始社会公有制逐步被私有制所取代,与经济基础的变革相适应,禅让制被王位世袭制所取代。

因此,世袭制代替禅让制是生产力发展的必然结果和时代进步的要求。

故C项正确;王位世袭制取代禅让制是阶级对立的产物,并不能体现该制度代表了先进阶级的利益。

故A项错误;奴隶社会取代原始社会,标志着人类社会从愚昧时代进入文明时代。

因此中国古代文明时代开始的标志是第一个国家的建立,即夏朝的建立,并非王位世袭制。

故B项错误;华夏族的形成要追溯至炎黄时期,并非在夏朝形成,且不能简单以一项政治制度的更替作为华夏族形成的标志。

故D项错误。

3. “封建亲戚,以藩屏周。

”这句话指的是( )A. 分封制B. 井田制C. 郡县制D. 行省制【答案】A【解析】试题分析:材料中“封建亲戚,以藩屏周”,意思是将西周的宗族姻亲分封到各地,广建子国,构筑一道屏障,来捍卫周天子的中央权威。

AMany years ago, when I was fresh out of school and working in Denver, I was driving to my parents’ home in Missouri for Christmas. I stopped at a gas station about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register (收款台), I said hello to an older couple who were also paying for gas.I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken t o at the gas station. They said they would take me to my friend’s. We chatted on the way into the city, and when I got out of the car, the husband gave me his business card.I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I’d left the li ghts on all day, and the battery (电池) was dead. Then I noticed that the Friendly Ford dealership—a shop selling cars—was right next door. I walked over and found two salesmen in the showroom.“Just how friendly is Friendly Ford?” I asked and explained my t rouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said.“Thank you” —two powerful words. They’re easy to say and mean so much.1. What happened when the author found smoke coming out of his car?A.He had it pulled back to the gas station. B.The couple sent him a business card.C.The couple offered to help him. D.He called his friend for help.2. The battery of the author’s car was dead because ________.A.something went wrong with the lights B.the meeting lasted a whole dayC.he forgot to turn off the lights D.he drove too long a distance3. By telling his own experiences, the author tries to show ________.A.how to write a thank-you letter B.how to deal with car problemsC.the kind-heartedness of older people D.the importance of expressing thanksBPeople in the United States honor their parents with two special days:Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible (有责任感的) citizens. They give love and care. These two days make us think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child care.These two special days a re celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery (墓地).On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays.4. Which of the following is NOT a reason for children to show love and respect for parents?A. Parents bring up children.B. Parents give love and care to children.C. Parents educate children to be good persons.D. Parents pass away before children grow up.5. What do you think “florists” do?A. They sell flowers.B. They make and sell bread.C. They offer enough room for having family parties.D. They sell special gifts for Mother’s Day and Father’s Day.6. What do you know from the passage?A. Mother’s Day and Father’s Day are both in May.B. Fewer women worked outside the home in the past.C. Not all the children respect their parentsD. Fathers are not as important as mothers at home.7. On Mother’s Day and Father’s Day, ________.A. people usually have family partiesB. everyone goes to visit the cemeteryC. children always go to parents’ homeD. hand-made cards are the most valuable giftsCFootball T-shirts are more commonly connected with boys than girls. This can often cause a problem when you want to find a cool shirt for a girl. That is not to say that there are no cool shirts out there for girls to wear. The problem is that they are often harder to find than the ones for boys.You can get custom (订制的) shirt printed for girls from a number of custom print stores. Of course you have to make sure that they are legally allowed to use the logos (商标) and colours of the team you want to support.You can also go through official channels to get the shirt you want. The official channels will generally be the large sportswear stores or the official stores of the teams. These stores will be able to use the colours of the teams and even put the name of the person who the shirt is for on it.If you do not feel like you have to try the T-shirts on, then an online store may be your best choice. The reason for this is that you can visit various stores and find the best ones.If you want to see what the T-shirt looks like in real life, then going to a store is the best choice. Large sportswear stores often have football shirts. These are the best places to go if you do not live close to an official store. And these stores usually have lower prices than the official stores.8. According to the text, football T-shirts ________.A. are all made by boysB. are seldom loved by girlsC. are only designed for boysD. are difficult to find for girls9. According to the text, custom print stores ________.A. could use any colours and logos as they likeB. should be operated by the football teamsC. could print anything that official stores sellD. should legally use your favourite logos10. If you don’t need to try the T-shirts on, you can visit ________.A. official storesB. online storesC. large sportswear storesD. custom print stores11. What kind of readers is this passage for?A. Football players.B. Clothes store owners.C. Female football fans.D. Physical education teacherDEnglish songs have been very popular for people around the world for many decades. Songs from Elvis Presley to Ricky Martin, from the Beatles to Eminem and from Natalie Cole to Britney Spears have all been enjoyed by people around the world, even for people who don’t speak English, and even for people who speak zero English.From my experience, some people listen to English songs for 20-30 years but still don’t achieve any good English skills. Some people choose English songs to be their main learning method, but most of them fail.Listening to English songs does not help you to speak English fluently. It does help you gain some vocabulary, but most of these words are unusua l ones that you don’t use in everyday life. You won’t learn the sentence “It is a difficult project. We really need to meet the deadline.” in any English songs. All you will hear are love, passion, affection, hate and blue, for the feeling, not the color.People like using English songs to practice English skills because it’s easy and enjoyable. They think that sitting in the car listening to English songs day after day will improve their English skills. It actually will not.You will definitely not improve your listening skills because normal people don’t speak with a tune. People don’t talk like Eminem’s songs. You can’t get yourself familiar with English pronunciation or accent just from listening to English songs. The words that they pronounce in the songs are not the words that you will hear in your everyday life. They can even confuse you more about how English is pronounced.I would fully encourage you to watch English movies and listen to radio news or other normal talks, but not music. Of course, you can consume it for fun but not with the aim of improving your English skills. Having good English skills is not that easy. Remember you should work hard to improve your English step by step.12. According to the passage, listening to English songs can help you _____A. improve your English grammarB. speak English more fluentlyC. gain the skills of writingD. learn more new words13. Which of the following statements is NOT true according to the passage?A. Most people think it is convenient to learn English by listening to English songs.B. It’s hard for people to improve their listening skills by listening to English songs.C. It’s a good idea to learn to speak with an English accent by listening to English songs.D. It’s rare to hear normal p eople speak English like they are singing.14. What can we learn about the words in English songs?A. Most of them are vivid and interesting.B. They are seldom used in people’s everyday life.C. English learners should learn more of them.D. They can help people improve their pronunciation.15. It can be inferred from the passage that the writer may be _____.A. an experienced English learnerB. a well-known pop singerC. a Chinese music fanD. an American teacher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入空白处的最佳选项。
