(II)因为f (x )在区间[0,3π8]上是增函数,在区间[3π8,π2]上是减函数.又f (0)=-2,f (3π8)=22,f (π2)=2,故函数f (x )在区间[0,π2]上的最大值为2 2,最小值为-2. 16.解:(I)设“取出的4张卡片中,含有编号为3的卡片”为事件A ,则P (A )=C 12C 35+C 22C 25C 47=67. 所以,取出的4张卡片中,含有编号为3的卡片的概率为67.(II)随机变量X 的所有可能取值为1,2,3,4.P (X =1)=C 33C 47=135,P (X =2)=C 34C 47=435,P (X =3)=C 35C 47=27,P (X =4)=C 36C 47=47.所以随机变量X 的分布列是随机变量X 的数学期望E (X )=1×135+2×435+3×27+4×47=175.17.解法一:如答图1,以点A 为原点建立空间直角坐标系,依题意得A (0,0,0),B (0,0,2),C (1,0,1),B 1(0,2,2),C 1(1,2,1),E (0,1,0).答图1(I)证明:易得B 1C 1→=(1,0,-1),CE →=(-1,1,-1),于是B 1C 1→·CE →=0,所以B 1C 1⊥CE .(II) B 1C →=(1,-2,-1),设平面B 1CE 的法向量m =(x ,y ,z ), 则10,0,B C CE ⎧⋅=⎪⎨⋅=⎪⎩m m 即⎩⎨⎧x -2y -z =0,-x +y -z =0,消去x ,得y +2z =0,不妨令z =1,可得一个法向量为m =(-3,-2,1).由(1),B 1C 1⊥CE ,又CC 1⊥B 1C 1,可得B 1C 1⊥平面CEC 1,故B 1C 1→=(1,0,-1)为平面CEC 1的一个法向量.于是cos 〈m ,B 1C 1→〉=m ·B 1C 1→|m |·|B 1C 1→|=-414×2=-2 77,从而sin 〈m ,B 1C 1→〉=217.所以二面角B 1-CE -C 1的正弦值为217. (III)AE →=(0,1,0),EC 1→=(1,1,1).设EM →=λEC 1→=(λ,λ,λ),0≤λ≤1,有AM →=AE →+EM →=(λ,λ+1,λ).可取AB →=(0,0,2)为平面ADD 1A 1的一个法向量.设θ为直线AM 与平面ADD 1A 1所成的角,则sin θ=|cos 〈AM →,AB →〉|=|AM →·AB →||AM →|·|AB →|=2λλ2+(λ+1)2+λ2×2=λ3λ2+2λ+1. 于是λ3λ2+2λ+1=26,解得λ=13(负值舍去),所以AM = 2.解法二:(I)因为侧棱CC 1⊥平面A 1B 1C 1D 1,B 1C 1⊂平面A 1B 1C 1D 1,所以CC 1⊥B 1C 1.经计算可得B 1E =5,B 1C 1=2,EC 1=3,从而B 1E 2=B 1C 21+EC 21,所以在△B 1EC 1中,B 1C 1⊥C 1E .又CC 1,C 1E ⊂平面CC 1E ,CC 1∩C 1E =C 1,所以B 1C 1⊥平面CC 1E ,又CE ⊂平面CC 1E ,故B 1C 1⊥CE.答图2(II)如答图2,过B 1 作B 1G ⊥CE 于点G ,连接C 1G .由(I),B 1C 1⊥CE .故CE ⊥平面B 1C 1G ,得CE ⊥C 1G ,所以∠B 1GC 1为二面角B 1-CE -C 1的平面角.在△CC 1E 中,由CE =C 1E =3,CC 1=2,可得C 1G =2 63.在Rt △B 1C 1G 中,B 1G =423,所以sin ∠B 1GC 1=217,即二面角B 1-CE -C 1的正弦值为217.(III)如答图2,连接D 1E, 过点M 作MH ⊥ED 1于点H ,可得MH ⊥平面ADD 1A 1,连接AH ,AM ,则∠MAH为直线AM 与平面ADD 1A 1所成的角.设AM =x ,从而在Rt △AHM 中,有MH =26x ,AH =346x .在Rt △C 1D 1E 中,C 1D 1=1,ED 1=2,得EH =2MH =13x .在△AEH 中,∠AEH =135°,AE =1,由AH 2=AE 2+EH 2-2AE ·EH cos 135°,得1718x 2=1+19x 2+23x . 整理得5x 2-22x -6=0,解得x =2(负值舍去),所以线段AM 的长为 2.18.解:(I)设F (-c ,0),由c a =33,知a =3c .过点F 且与x 轴垂直的直线为x =-c ,代入椭圆的方程有(-c )2a 2+y 2b 2=1,解得y =±6b 3.于是2 6b 3=4 33,解得b = 2. 又a 2-c 2=b 2,从而a =3,c =1, 所以所求椭圆的方程为x 23+y 22=1.(II)设点C (x 1,y 1),D (x 2,y 2),由F (-1,0)得直线CD 的方程为y =k (x +1).由方程组⎩⎨⎧y =k (x +1),x 23+y 22=1,消去y ,整理得(2+3k 2)x 2+6k 2x +3k 2-6=0,可得x 1+x 2=-6k 22+3k 2,x 1x 2=3k 2-62+3k 2.因为A (-3,0),B (3,0),所以AC →·DB →+AD →·CB →=(x 1+3,y 1)·(3-x 2,-y 2)+(x 2+3,y 2)·(3-x 1,-y 1) =6-2x 1x 2-2y 1y 2=6-2x 1x 2-2k 2(x 1+1)(x 2+1) =6-(2+2k 2)x 1x 2-2k 2(x 1+x 2)-2k 2 =6+2k 2+122+3k 2.由已知得6+2k 2+122+3k 2=8,解得k =± 2.19.解:(I)设等比数列{a n }的公比为q ,因为S 3+a 3,S 5+a 5,S 4+a 4成等差数列,所以S 5+a 5-S 3-a 3=S 4+a 4-S 5-a 5,即4a 5=a 3,于是q 2=a 5a 3=14.又{a n }不是递减数列且a 1=32,所以q =-12,故等比数列{a n }的通项公式为a n =32×(-12)n -1=(-1)n -1·32n .(II)由(I)得S n =1-(-12)n =⎩⎪⎨⎪⎧1+12n ,n 为奇数,1-12n ,n 为偶数.当n 为奇数时,S n 随n 的增大而减小,所以1<S n ≤S 1=32,故0<S n -1S n ≤S 1-1S 1=32-23=56.10 / 11 当n 为偶数时,S n 随n 的增大而增大,所以34=S 2≤S n <1,故0>S n -1S n ≥S 2-1S 2=34-43=-712. 综上,对于n ∈N *,总有-712≤S n -1S n ≤56. 所以数列{T n }最大项的值为56,最小项的值为-712. 20.解:(I)函数f (x )的定义域为(0,+∞).f ′(x )=2x ln x +x =x (2ln x +1),令f ′(x )=0,得x =1e . 当x 变化时,f ′(x ),f (x )的变化情况如下表: 递减 递增 所以函数f (x )的单调递减区间是(0,1e ),单调递增区间是(1e ,+∞). (II)当0<x ≤1时,f (x )≤0,设t >0,令h (x )=f (x )-t ,x ∈[1,+∞).由(I)知,h (x )在区间(1,+∞)内单调递增.h (1)=-t <0,h (e t )=e 2t ln e t -t =t (e 2t -1)>0.故存在唯一的s ∈(1,+∞),使得t =f (s )成立.(III)因为s =g (t ),由(II )知,t =f (s ),且s >1,从而ln g (t )ln t =ln s ln f (s )=ln s ln (s 2ln s )=ln s 2ln s +ln ln s =u 2u +ln u, 其中u =ln s .要使25<ln g (t )ln t <12成立,只需0<ln u <u 2. 当t >e 2时,若s =g (t )≤e ,则由f (s )的单调性,有t =f (s )≤f (e)=e 2,矛盾.所以s >e ,即u >1,从而ln u >0成立.另一方面,令F (u )=ln u -u 2,u >1.F ′(u )=1u -12,令F ′(u )=0,得u =2.当1<u <2时,F ′(u )>0;当u >2时.F ′(u )<0,故对u >1,F (u )≤F (2)<0,因此ln u <u 2成立. 综上,当t >e 2时,有25<ln g (t )ln t <12.。

k2013天津高考语文试题及答案

类信息的人力和财力,而一些具有休闲娱乐特色的微博也为大众"粉丝"提供了茶余饭后的谈资。

传统的"粉丝"群体和社团要获得有关"粉丝"客体的信息,通常需由第三方提供,例如借助电视娱乐节目、广播和报纸的娱乐板块,或者是"粉丝"团能够接触到的明星的领导层提供的消息。

微博的产生无疑舍弃了第三方这一环节,"粉丝"只需通过关注名人微博,就可以即时接收明星发布的所有消息,甚至可以在明星微博下进行"评论",这就给"粉丝"创造出一种与名人直接互动交流的错觉。

"粉丝"在这种错觉之下认为自己与名人多了一层社会关系,是熟悉的双方的彼此关注。

6.下列对"微博粉丝"的表述,正确的一项是A."微博粉丝"精通现代媒体技术,热衷于使用微博,以此降低获取信息的成本。

B."微博粉丝"希望通过使用微博为自己获取名声和影响力,同时为大众建构生活的幻象。

C."微博粉丝"通过关注明星偶像的微博,接收信息或发表评论,可以得到貌似直接交流的其实是建立在心理错觉之上的快感体验。

D."微博粉丝"为应对自己遇到的痛、挫败、恐惧等,而把精力投入到微博上,为大众"粉丝"提供谈资。

7.下列对本文有关内容的理解,不正确的一项是A.使用微博以满足自己的社会、心理需求是"微博粉丝"存在与发展的主要原因。

B."微博粉丝"和传统"粉丝"都能获得一种投射在偶像身上的替代性满足,在追星的过程中实现自我认同。

C.关注机构官方微博和权威人士微博的"非忠实粉丝"对"粉丝"客体的态度,通常比专门追星和"微博粉丝"要冷静务实。

This population consists of birds,bats frogs,snakes,etc. For example,outdoor lighting severely affects migrating(迁徙的)birds.According to the International Dark-Sky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”Countless more animals casualties(伤亡)result from the use of artificial lighting.Clearly,people enjoy the benefits of lighting their evenings,but some scientists think it can be harmful for humans,too. They worry that exposure to light while sleeping can increase person’s chances of getting cancer.Emerald Valley is only one community that is becoming aware of the negative effects of hight pollution.For years,Flagstaff,Arizona,has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.Similar efforts have been made worldwide,and a movement is underway to remind us to turn off lights when we are not using them,so that other creatures can share the night.22)It happened last night thatA.the city’s lights affected the meteor watchingB.the meteors flew past before being noticedC.the city light show attracted many peopleD.the meteor watching ended up a social outing42.What do the astronomers complain about?A.Meteor showers occur less often than beforeB.Their observation equipment is in poor repairC.Light pollution has remained unsolved for yearsD.Their eyesight is failing due to artificial lighting43.What the author concerned about according to Paragraph 4?A.Birds may take other migration pathsB.Animal’living habits may change suddenlyC.Varieties of animals will become sharply reducedD.Animals’survival is threatened by outdoor lighting44.Lighting regulations in Flagstaff,Arizona are put into effect toA.Lessen the chance of getting cancerB.create an ideal observation conditionC.ensure citizens a good sleep at nightD.enable all creatures to live in harmony45.What message does the author most want to give us?A.Saving wildlife is saving ourselvesB.Great efforts should be made to save energyC.Human activities should be environmentally friendlyD.New equipment should be introduced for space studyC.Poet William Stafford once said that we are defined more by the detours(绕行路)in life that by the narrow road toward goals.I like this image.But I as quite by accident that I discovered the deep meaning of his words. For years we made the long drive from our home in Seattle to my parents’ home in Boise in nine hours.We traveled the way most people do:the fastest,shortest easiest road,especially when ai was alone with fournoisy,restless kids who hates confinement(限制)and have strong opinions about everything.Road trips felt risky,so I would drive fast,stopping only when I had to.We would stick to the freeways and arrive tired.But then Banner,our lamb was born.He was rejected by his mama days before our planned trip to Boise.I had two choices:leave Banner with my husband,or take him with me.My husband made the decision for me.That is how I found my self on the road with four kids,a baby lamb and nothing but my everlasting optimism to see me through.We took the country roads out of necessity.We had to stop every hour,let Banner shke out his legs and feed him.The kids chased him and one another.They’d get back in the car breathless and energized,smelling fresh from the cold air.We explored side roads,catching grasshoppers in waist-high grass.Even if we simply looked out of the car windows at baby pigs following their mother,or fish leaping out of the water,it was better than the best ride down the freeway. Here was life.And new horizons(见识).We eventually arrived at my parents’doorstep astonishingly fresh and full of storiesI grew brave with the trip back home and creative with my disciplining technique.On an empty section of road,everyone started quarreling.I stopped the car,ordered all kids out and told them to meet me up ahead.I parked my car half a mile away and read my book in sweet silence.Some road trips are by necessity fast and straight.But that trip with Banner opened our eyes to a world available to anyon adventurous enough to wander around and made me realize that a detour may uncover the best part of a journey----and the best part of yourself.46.Why did the author use to take freeways to her parents’home?A.It was less timeB.It would be faster and saferC.Her kids would feel less confinedD.She felt better with other drivers nearby47.The author stopped regularly on the country roads toA.relax in the fresh airB.take a dep breathC.take care of the lambD.let the kids play with Banner48.What does the author discover from the trip according to Paragraph 6?A.Freeways are where beauty hides.B.Getting close to nature adds to the joy of lifeC.Enjoying the beauty of nature benefits one’s healthD.One should follow side roads to watch wild animals49.Why did the author ask the kids to get out of the car on their way back home?A.To give herself some time to readB.To order some food for themC.To play a game with them.D.To let them cool down50.What could be the best title for the passage?A.Charm of the DetourB.The Road to BraveryC.Creativity out of NecessityD.Road trip and Country LifeD.When asked about happiness,we usually think of something extraordinary, an absolute delight,which seems to get rarer the older we get.For kids,happiness has a magical quality.Their delight at winning a race or getting a new bike is unreserved(毫不掩饰的).In the teenage years the concept of happiness changes.Suddenly it’s conditional on such things as excitement,love and popularity.I can still recall the excitement of being invited to dance with the most attractive boy at the school party.In adulthood the things that bring deep joy----love,marriage,birth----also bring responsibility and the risk of loss.For adults,happiness is complicated(复杂的)My definition fo happiness is “the capacity for enjoyment”.The more we can enjoy what we have,the hap pier we are.It’s easy to overlook the pleasure we get from the company of friends,the freedom to live where we please,and even goo health.I experienced my little moments of pleasure yesterday.First I was overjoyed when I shut the last lunch-box and had the house to myself.Then I spent an uninterrupted morning writing,which I love.When the kids and my husband came home,I enjoyed their noise after the quiet of the day.Psychologists tell us that to be happy we need a mix of enjoyable leisure time and sat isfying work.I don’t think that my grandmother,who raised 14 children,had much of either.She did have a network of close friends and family,and maybe this is what satisfied her.We,however,with so many choices and such pressure to succeed in every area,have turned happiness into one more thing we’ve got to have.We’ve so self-conscious about our “right” to it that it’s making us miserable.So we chase it and equal it with wealth and success,without noticing that the people who have those things aren’t necessarily happierHappiness isn’t about what happens to us----it’s about how we see what happens to us.It’s the skillful way of finding a positive for every negative.It’s not wishing for what we don’t have,but enjoying what we do possess.51.As people grow older,theyA.feel it harder to experience happinessB.associate their happiness less with othersC.will take fewer risks in pursuing happinessD.tend to believe responsibility means happiness52.What can we learn about the author from Paragraph 5 and 6?A.She cares little about her own healthB.She enjoys the freedom of travelingC.She is easily pleased by things in daily lifeD.She prefers getting pleasure from housework53.What can b informed from Paragraph 7?A.Psychologists think satisfying work is key to happinessB.Psychologists’opinion is well proved by Grandma’caseC.Grandma often found time for social gatheringsD.Grandma’s happiness came from modest expectations of life54.People who equal happiness with wealth and successA.consider pressure something blocking their wayB.stress then right to happiness too muchC.are at a loss to make correct choicesD.are more likely to be happy55.What can be concluded from the passage?A.Happiness lies between the positive and the negativeB.Each man is the master of his own fateC.Success leads to happinessD.Happy is he who is content四、阅读表达My name is Clara.I still remember that chilly December day,sitting in science class.I’d finished a worksheet early and picked up a TIME for Kids magazine. A piece of news caught my eye:NASA was holding an essay contest to name its Mars rover(火星探测器).Before I even knew anything else about it,a single word flooded my 11-year-old mind,Curiosity.I couldn’t want for the bell to ring so I could get started on my essay.That afternoon,I raced home,sat do wn at the computer,and typed until my fingers ached. “Curiosity is an everlasting flame that burns in everyone’s mind...”Five months later, my mon received a phone call,and immediately, a wide smile spread across her face.On August 5,2012,at 10:31 p.m,the rover named Curiosity touched down safely on the surface of Mars,and I was honored to have a front-row seat in NASA.Curiosity is such an important part of who I am.I have always been fascinated by the stars,the planets,the sky and the universe. I remember as a little girl,my grandmother and I would sit together in the backyard forhours.She’d tell me stories and point out the stars,Grandma lived in China,thousands of miles away from my home in Kansas,but the stars kept us together even when we were apart.They were always there, yet there was so much I didn’t know about them.That’s what I love so much about space.People often ask me why we go to faraway places like Mares.My answer is simple because we’re curious.We human beings do not just hole up in one place.We are constantly wondering and trying to find out what’s over the hill and beyond the horizon.56.How did Clara get the new about the essay contest?( no more than 10 words)57.Why did Clara have a front-row seat in NASA?( no more than 10 words)58.What does Clara remember about the time spent with Grandma?( no more than 15 words)59.What does the underlined phrase “hole up”mean?(1 word)60.In your opinion,why is curiosity important?( no more than 20 words)五、书面表达61.假设你是某大学的学生李津,你校英语俱乐部将选举新一届副主席,负责规划、组织俱乐部的相关活动,你欲参选,请按以下提示,写一篇竞选演讲稿。

绝密★启用前2013年普通高等学校招生全国统一考试(天津卷)文科综合历史部分试题1.右图为《岛夷志略》片段。

从其内容判断,该著作的出现应不晚于A.秦汉时期B.隋唐时期C.宋元时期D.明清时期【答案】C【解析】本题以中国古代中央对地方的行政管辖为切入点,旨在考查考生获取图片信息和运用历史知识说明现实问题的能力。

本题一定要抓住图片中“万里石塘”这一关键信息,联系教材中元朝行省图中的信息进行对比,就可以得出结论:“万里石塘”即元朝所管辖的南海地区。

故选C项。

2.“从宋代起,棉花开始成为一种重要纺织原料……到了元代,丝、麻、棉鼎足而三,明代以后,棉花的重要性超过麻。

”出现这些变化的前提条件是A.政府的大力推广B.棉纺织技术的改进C.商品经济的发展D.棉花成为经济作物【答案】B【解析】本题以中国古代纺织原料的变化为切入点,旨在考查考生对古代手工业技术进步的理解能力。

解答本题的关键是要区别棉花种植的不断扩大与棉花能够成为主要的“纺织原料”在原因上的不同。

A项政府的大力推广、C项商品经济的发展、D项棉花成为经济作物,这些条件都不同程度地推动了棉花种植的扩大。

但是,棉花能够逐渐成为主要的“纺织原料”,其前提条件还是棉纺织技术的改进,故选B项。

3.孟德斯鸠认为,共和政体是全体人民或仅仅一部分人民握有最高权力的政体;君主政体是由单独一个人遵照固定的和确立了的法律执政;专制政体是按一个人的意志行使权力。

他主张实行的政体是A.民主共和B.贵族共和C.君主立宪D.君主专制【答案】C【解析】本题以孟德斯鸠的政治主张为切入点,旨在考查考生解读材料信息和运用知识的能力。

根据题干信息“共和政体……仅仅一部分人民握有最高权力的政体”和“专制政体是按一个人的意志行使权力”的语义色彩,结合所学知识,我们不难判断孟德斯鸠是反对这两种政体形式的,故排除A、D两项。

贵族共和政体是少数贵族的“集体”统治,材料中没有体现,故排除B项。

根据题干信息:“君主政体是由单独一个人遵照固定的和确立了的法律执政”,这符合孟德斯鸠“依法治国”的根本理念,再结合所学知识判断,C项正确。
