=2,则输入x 的取值X 围是(28,57] .解:当输出k =2时,应满足 2x+1≤115,解得28<x ≤57. 2(2x+1)+1>11512.数列{a n }满足:a 1=2,a n =1-1a n -1(n =2,3,4,…),则a 12=-1.解:由已知a 1=2,a 2=1-1a 1=12,a 3=1-1a 2=-1,a 4=1-1a 3=2,可知{a n }是周期为3的周期数列,则a 12=a 3×4=a 3=-1. 13.已知函数f (x )=|x -2|,若a ≠0,且a ,b ∈R ,都有不等式|a +b |+|a -b |≥|a |·f (x )成立,则实数x 的取值X 围是 [0,4] .解:|a +b |+|a -b |≥|a |·f (x )及a ≠0得f (x )≤|a +b |+|a -b ||a |恒成立,而|a +b |+|a -b ||a |≥|a +b +a -b ||a |=2,则f (x )≤2,从而|x -2|≤2,解得0≤x ≤4.14.在△ABC 中有如下结论:“若点M 为△ABC 的重心,则MA +MB +MC =0”,设a ,b ,c 分别为△ABC 的内角A ,B ,C 的对边,点M 为△ABC 的重心.如果a MA +b MB +33c MC =0,则内角A 的大小为π6;若a =3,则△ABC 的面积为934. 解:由a MA +b MB +33c MC =a MA +b MB +33c (-MA -MB )=(a -33c )MA +(b -33c )MB =0. 又MA 与MB 不共线,则a =33c =b ,由余弦定理可求得cos A =32,故A =π6. 又S △=12bc sin A =12×3×33×12=934.15.给定集合A ={a 1,a 2,a 3,…,a n }(n ∈N ,n ≥3),定义a i +a j (1≤i <j ≤n ,i ,j ∈N )中所有不同值的个数为集合A 两元素和的容量,用L (A )表示,若A ={2,4,6,8},则L (A )=5;若数列{a n }是等差数列,设集合A ={a 1,a 2,a 3,…,a m }(其中m ∈N *,m 为常数),则L (A )关于m 的表达式为2m -3.解:①∵2+4=6,2+6=8,2+8=10,4+6=10,4+8=12,6+8=14,∴L (A )=5.②不妨设数列{a n }是递增等差数列可知a 1<a 2<a 3<…<a m ,则a 1+a 2<a 1+a 3<…<a 1+a m <a 2+a m <…<a m -1+a m ,故a i +a j (1≤i <j ≤m )中至少有2m -3个不同的数.又据等差数列的性质:当i +j ≤m 时,a i +a j =a 1+a i +j -1; 当i +j >m 时,a i +a j =a i +j -m +a m ,因此每个和a i +a j (1≤i <j ≤m )等于a 1+a k (2≤k ≤m )中一个, 或者等于a l +a m (2≤l ≤m -1)中的一个.故L (A )=2m -3.三、解答题:本大题共6小题,共75分.解答应写出文字说明,证明过程或演算步骤. 16.(本小题满分12分)若盒中装有同一型号的灯泡共12只,其中有9只合格品,3只次品.(1)某工人师傅有放回地连续从该盒中取灯泡3次,每次取一只灯泡,求2次取到次品的概率;(2)某工人师傅用该盒中的灯泡去更换会议室的一只已坏灯泡,每次从中取一灯泡,若是正品则用它更换已坏灯泡,若是次品则将其报废(不再放回原盒中),求成功更换会议室的已坏灯泡前取出的次品灯泡只数X 的分布列和数学期望.解:(1)每次取到一只次品的概率P 1=C 13C 112=14,则有放回连续取3次,其中2次取得次品的概率P =C 23(14)2·(1-14)=964.(5分) (2)依题知X 的可能取值为0、1、2、3.(6分) 且P(X =0)=912=34,P(X =1)=312×911=944,P(X =2)=312×211×910=9220,P(X =3)=312×211×110×99=1220.(8分)则X 的分布列如下表:(10分)EX =0×34+1×944+2×9220+3×1220=310.(12分)17.(本小题满分12分)已知函数f(x)=2sin ωx·cos (ωx +π6)+12(ω>0)的最小正周期为4π.(1)求正实数ω的值;(2)在△ABC 中,内角A 、B 、C 的对边分别为a 、b 、c ,且满足2b cos A =a cos C +c cos A ,求f(A)的值.解:(1)∵f(x)=2sin ωx(cos ωx·cos π6-sin ωx·sin π6)+12(2分)=3sin ωx cos ωx -sin 2ωx +12=32sin 2ωx -12(1-cos 2ωx)+12=sin (2ωx +π6).(5分) 又f(x)的最小正周期T =2π2ω=4π,则ω=14.(6分)(2)由2b cos A =a cos C +c cos A 及正弦定理可得2sin B cos A =sin A cos C +sin C cos A =sin (A +C).又A +B +C =π,则2sin B cos A =sin B.(8分)而sin B≠0,则cos A =12.又A ∈(0,π),故A =π3.(10分)由(1)f(x)=sin (x 2+π6),从而f(A)=sin (π3×12+π6)=sin π3=32.(12分)18.(本小题满分12分)已知数列{a n }的前三项与数列{b n }的前三项对应相等,且a 1+2a 2+22a 3+…+2n -1a n =8n 对任意的n ∈N *都成立,数列{b n +1-b n }是等差数列.(1)求数列{a n }与{b n }的通项公式;(2)是否存在k ∈N *,使得b k -a k ∈(0,1)?请说明理由.解:(1)已知a 1+2a 2+22a 3+…+2n -1a n =8n (n ∈N *).① n ≥2时,a 1+2a 2+22a 3+…+2n -2a n -1=8(n -1)(n ∈N *).②①-②得2n -1a n =8,解得a n =24-n ,在①中令n =1,可得a 1=8=24-1, 所以a n =24-n (n ∈N *).(4分)由题意b 1=8,b 2=4,b 3=2,所以b 2-b 1=-4,b 3-b 2=-2, ∴数列{b n +1-b n }的公差为-2-(-4)=2, ∴b n +1-b n =-4+(n -1)×2=2n -6, b n =b 1+(b 2-b 1)+(b 3-b 2)+…+(b n -b n -1)=8+(-4)+(-2)+…+(2n -8)=n 2-7n +14(n ∈N *).(8分)(2)b k -a k =k 2-7k +14-24-k ,当k ≥4时,f (k )=(k -72)2+74-24-k 单调递增,且f (4)=1,所以k ≥4时,f (k )=k 2-7k +14-24-k ≥1.又f (1)=f (2)=f (3)=0,所以,不存在k ∈N *,使得b k -a k ∈(0,1).(12分) 19.(本小题满分13分)某化工厂生产某种产品,每件产品的生产成本是3元,根据市场调查,预计每件产品的出厂价为x 元(7≤x ≤10)时,一年的产量为(11-x )2万件;若该企业所生产的产品全部销售,则称该企业正常生产;但为了保护环境,用于污染治理的费用与产量成正比,比例系数为常数a (1≤a ≤3).(1)求该企业正常生产一年的利润L (x )与出厂价x 的函数关系式;(2)当每件产品的出厂价定为多少元时,企业一年的利润最大,并求最大利润.解:(1)依题意,L (x )=(x -3)(11-x )2-a (11-x )2=(x -3-a )(11-x )2,x ∈[7,10].(4分)(2)因为L ′(x )=(11-x )2-2(x -3-a )(11-x )=(11-x )(11-x -2x +6+2a )=(11-x )(17+2a -3x ).由L ′(x )=0,得x =11[7,10]或x =17+2a 3.(6分) 因为1≤a ≤3,所以193≤17+2a 3≤233. ①当193≤17+2a 3≤7,即1≤a ≤2时,L ′(x )在[7,10]上恒为负,则L (x )在[7,10]上为减函数,所以[L (x )]max =L (7)=16(4-a ).(9分)②当7<17+2a 3≤233,即2<a ≤3时,[L (x )]max =L (17+2a 3)=427(8-a )3.(12分) 即当1≤a ≤2时,则每件产品出厂价为7元时,年利润最大,为16(4-a )万元.当2<a ≤3时,则每件产品出厂价为17+2a 3元时,年利润最大,为427(8-a )3万元.(13分) 20.(本小题满分13分)设函数y =f (x )的定义域为(0,+∞),且在(0,+∞)上单调递增,若对任意x ,y ∈(0,+∞)都有:f (xy )=f (x )+f (y )成立,数列{a n }满足:a 1=f (1)+1,f (12a n +1-12a n )+f (12a n +1+12a n)=0.设S n =a 21a 22+a 22a 23+a 23a 24+…+a 2n -1a 2n +a 2n a 2n +1.(1)求数列{a n }的通项公式,并求S n 关于n 的表达式;(2)设函数g (x )对任意x 、y 都有:g (x +y )=g (x )+g (y )+2xy ,若g (1)=1,正项数列{b n }满足:b 2n =g (12n ),T n 为数列{b n }的前n 项和,试比较4S n 与T n 的大小. 解:(1)当x ,y ∈(0,+∞)时,有f (xy )=f (x )+f (y ),令x =y =1得f (1)=2f (1),得f (1)=0,所以a 1=f (1)+1=1.(1分)因为f (12a n +1-12a n )+f (12a n +1+12a n )=0,所以f (14a 2n +1-14a 2n)=0=f (1). 又因为y =f (x )在(0,+∞)上是单调增函数,所以14a 2n +1-14a 2n =1,即1a 2n +1-1a 2n=4,(3分) 所以数列{1a 2n }是以1为首项,4为公差的等差数列,所以1a 2n=4n -3,所以a n =14n -3. ∵a 2n a 2n +1=1(4n -3)(4n +1)=14[14n -3-14n +1],∴S n =14[11-15+15-19+…+14n -3-14n +1]=14[1-14n +1].(5分) (2)由于任意x ,y ∈R 都有g (x +y )=g (x )+g (y )+2xy ,则g (2x )=2g (x )+2x 2,∴g (1)=2g (12)+2·(12)2=2[2g (14)+2·(14)2]+12=22g (14)+122+12=22[2g (123)+2·(123)2]+122+12=23g (123)+123+122+12=…=2n g (12n )+12n +12n -1+12n -2+…+122+12=1, ∴g (12n )=122n ,即b 2n =122n . 又b n >0,∴b n =12n ,(9分) ∴T n =12+122+…+12n =1-12n ,又4S n =1-14n +1. 当n =1,2,3,4时,4n +1>2n ,∴4S n >T n ;(10分)当n ≥5时,2n =C 0n +C 1n +C 2n +…+C n -1n +C n n >1+2n +2n (n -1)2=1+n 2+n . 而n 2+n +1-(4n +1)=n 2-3n =n (n -3)>0,故4S n <T n .(13分)(用数学归纳法证明参照计分)21.(本小题满分13分)定义F (x ,y )=(1+x )y ,其中x ,y ∈(0,+∞).(1)令函数f (x )=F (1,log 2(x 3+ax 2+bx +1)),其图象为曲线C ,若存在实数b 使得曲线C 在x 0(-4<x 0<-1)处有斜率为-8的切线,某某数a 的取值X 围;(2)令函数g (x )=F (1,log 2[(ln x -1)e x +x ]),是否存在实数x 0∈[1,e],使曲线y =g (x )在点x =x 0处的切线与y 轴垂直?若存在,求出x 0的值;若不存在,请说明理由.(3)当x ,y ∈N ,且x <y 时,求证:F (x ,y )>F (y ,x ).解:(1)f (x )=F (1,log 2(x 3+ax 2+bx +1))=x 3+ax 2+bx +1,设曲线C 在x 0(-4<x 0<-1)处有斜率为-8的切线,又由题设知log 2(x 3+ax 2+bx +1)>0,f ′(x )=3x 2+2ax +b ,3x 20+2ax 0+b=-8 ①∴存在实数b 使得 -4<x 0<-1 ②有解,(3分)x 30+ax 20+bx 0>0 ③由①得b =-8-3x 20-2ax 0,代入③得-2x 20-ax 0-8<0,∴由 2x 20+ax 0+8>0 有解,-4<x 0<-1得2×(-4)2+a ×(-4)+8>0或2×(-1)2+a ×(-1)+8>0, ∴a <10或a <10,∴a <10.(5分)(2)∵g (x )=(ln x -1)e x +x ,∴g ′(x )=(ln x -1)′e x +(ln x -1)(e x)′+1=e x x +(ln x -1)e x +1=(1x +ln x -1)e x +1.(6分) 设h (x )=1x +ln x -1.则h ′(x )=-1x 2+1x =x -1x2, 当x ∈[1,e]时,h ′(x )≥0.h (x )为增函数,因此h (x )在区间[1,e]上的最小值为ln1=0,即1x+ln x -1≥0. 当x 0∈[1,e]时,e x 0>0,1x 0+ln x 0-1≥0, ∴g ′(x 0)=(1x 0+ln x 0-1)e x 0+1≥1>0.(8分) 曲线y =g (x )在点x =x 0处的切线与y 轴垂直等价于方程g ′(x 0)=0有实数解. 而g ′(x 0)>0,即方程g ′(x 0)=0无实数解.故不存在实数x 0∈[1,e],使曲线y =g (x )在点x =x 0处的切线与y 轴垂直.(9分)(3)证明:令h (x )=ln(1+x )x ,x ≥1,由h ′(x )=x 1+x -ln(1+x )x 2, 又令p (x )=x 1+x-ln(1+x ),x ≥0, ∴p ′(x )=1(1+x )2-11+x =-x (1+x )2≤0, ∴p (x )在[0,+∞)上单调递减,∴当x >0时,有p (x )<p (0)=0,∴当x ≥1时,有h ′(x )<0,∴h (x )在[1,+∞)上单调递减,(11分)∴当1≤x <y 时,有ln(1+x )x >ln(1+y )y, ∴y ln(1+x )>x ln(1+y ),∴(1+x )y >(1+y )x ,∴当x ,y ∈N ,且x <y 时,F (x ,y )>F (y ,x ).(13分)。

六年高考四年模拟试题分类:诗鉴赏(补遗)13.(浙江省2010届高三第一次五校联考)阅读下面这首诗,完成后面问题。
灞上秋居马戴①灞原风雨定,晚见雁行频。
落叶他乡树,寒灯独夜人。
空园白露滴,孤壁野僧邻。
寄卧郊扉久,何年致此身?注:①马戴,生卒年不详,生活于中晚唐之交的动荡年代。
(1)前两联诗人所见哪些意象?流露了诗人怎样的情感?简析之。
(2)第三联用了什么表现手法?后两联抒发了诗人怎样的情怀?试作赏析。
答案(1)秋风秋雨、雁群、落叶、寒灯。
一个“频”字,既表明了雁群之多,又使人联想起雁急于投宿的惶急之状。
古人每见雁回,易惹思乡之情。
“落叶他乡树”,又见风雨中片片黄叶从树上飘落下来,寄居在孤寺中的诗人在他乡看到落叶的情景,不能不有所感触,“树高千丈,叶落归根”。
自己羁留异地,何时才能回到故乡东海呢?其心情之酸楚,完全渗透在这句诗的字里行间。
“寒灯独夜人”,一个“寒”字,一个“独”字,写尽客中凄凉孤独的况味。
(2)烘托手法。
“空园白露滴”用的是以“声”烘托“静”的手法,露滴的声音使人感到寂静,其中的人又是如何彻夜难眠,孤独。
“孤壁野僧邻”同样是用烘托的手法。
明明孑然一身,孤单无依,却偏说还有一个邻居,而这个邻居竟是一个绝迹尘世、犹如闲云野鹤的僧人。
与这样的野僧为邻,诗人的孤独无依就显得更加突出了。
“寄卧郊扉久,何年致此身?”诗人为了求取官职来到长安,在灞上已寄居多时,一直没有找到进身之阶,因而这里率直道出了怀才不遇的苦境和进身希望的渺茫。
14.(福建省子江中学2010届高三上学期12月月考)阅读下面这首古诗,回答问题。
小园【清】黎简水影动深树,山光窥短墙。
秋村黄叶满,一半入斜阳。
幽竹如人静,*寒花为我芳。
小园宜小立,新月似新霜。
【注:寒花,菊花。
】(1)你认为诗的首联中哪个字用得最好?为什么?请简要赏析。
(2)这首诗的后两联由物及人(诗人),请简要赏析诗中“人”的形象特点。
答案(1)答案一:“窥”。
角度巧(不说小园里的人越过短墙能看见墙外山光,却说“山光窥短墙”,好像那山光探头进入短墙,在窥视这小园中的景物,巧妙突出了小园景物之富于魅力);拟人化(以物拟人,写活了“山光”的意态神情,与王安石“两山排闼送青来”有异曲同工之妙)。

Choose the one that fits best according to the information given in the passage.AJamie Oliver has been invited by Gordon Brown to prepare a banquet at No. 10 for President Barack Obama and other leaders of the G20, offering a cut-price menu to reflect times when trade and industry are far from prosperous and the rate of employment is decreasing.Downing Street sources say Oliver, the well-known chef, will cook using “honest high-street products” and avoid expensive or “fancy” ingredients.The prime minister is trying to avoid a repeat of the embarrassment last year when he sat down to an 18-course banquet at a Japanese summit to discuss world food shortages.Obama, President Nicolas Sarkozy of France, Chancellor Angela Merkel of Germany and other leaders will be served by apprentices (学徒) from Fifteen, the London restaurant Oliver founded to help train young people in poverty in order to make a living by mastering a skill.Brown wants the dinner to reflect the emphasis of the London summit, which he hopes will lead to an agreement to lift the world out of recession. “To be invited to cook for such an important group of people, who are trying to solve some of the world’s major problems, is really a privilege,” said Oliver.“I’m hoping the menu I’m working on will show British food and produce is some of the best in the world, but also show we have pioneered a high-quality apprentice scheme at Fifteen London that is giving young people a skill to be proud of.”The chef has not yet finalized the menu, but is expected to draw inspiration from his latest book, Jamie’s Ministry of Food, which has budget recipes for beef and ale stew (啤酒炖菜) and “impressive”chocolate fudge cake.56.

Hindi is the national, official, and main link language of India. English is an associate official language. The Indian Constitution also officially approves twenty-two regional languages for official purposes.Dozens of distinctly different regional languages are spoken in India, which share many characteristics such as grammatical structure and vocabulary. Apart from these languages, Hindi is used for communication in India. The homeland of Hindi is mainly in the north of India, but it is spoken and widely understood in all urban centers of India. In the southern states of India, where people speak many different languages that are not much related to Hindi, there is more resistance to Hindi, which has allowed English to remain a lingua franca(混合语)to a greater degree. Since the early 1600s, the English language has had a toehold on the Indian subcontinent, when the East India Company established settlements in Chennai, Kolkata, and Mumbai, formerly Madras, Calcutta, and Bombay respectively. The historical background of India is never far away from everyday usage of English. India has had a longer exposure to English than any other country which uses it as a second language, its distinctive words, idioms, grammar and rhetoric spreading gradually to affect all places, habits and culture.In India, English serves two purposes. First, it provides a linguistic tool for the administrative cohesiveness of the country, causing people who speak different languages to become united. Secondly, it serves as a language of wider communication, including a large variety of different people covering a vast area. It overlaps with local languages in certain spheres of influence and in public domains.English has special national status in India. It has a special place in the parliament, judiciary, broadcasting, journalism, and in the education system. One can see a Hindi-speaking teacher giving their students instructions during an educational tour about where to meet and when their bus would leave, but all in English. It means that the language permeates daily life. It is unavoidable and is always expected, especially in the cities.61. According to the writer, the Indian constitution recognizes_______.A. 22 official languagesB. Hindi as the national languageC. 2 national, official languagesD. 2 national languages62.

At an exercise in November 2008, more than 500 people from 70 different agencies were involved in running scenarios for the Games. Two further exercises are planned this year, said Mercer.Military camps are planned for the Sea-to-Sky highway linking Vancouver and Whistler, B.C. in order to patrol the backcountry and keep watch on the vital Games artery.Secure zones will be established around all venues and handheld screening equipment will be used at entrances.A network of surveillance cameras will also be in place, and the equipment that can scan for biological or nuclear threats will also reportedly be used.As to reports that terrorists are a threat and may go as for as infiltration contractors to gain accessto security planning, Mercer said,” Our threat at present is low.”“ I know where the security plans are, the security plans are secure, they’re safe, they’re locked up an d they’re not in any danger of being leaked or be in the hands of anybody we wouldn’t want them to be in.” Mercer said his goal is not only to ensure safety, but also best service. “ I’ll be personally disappointed if anybody left here and all they remembe red was security,” he said,” So our goal is to do it the Canadian way. Security will be there, security will be subtle, security will be friendly based on the threat level we’re at today.”66.

Complete the diagram / Fill in the numbered blanks by using the information for the passage.Write NO MORE THAN 3 WORDS for each answer.Why must we pay taxes? The answer is that the government needs money for many things, for example, to pay its soldiers, sailors and airmen, to build roads, bridges, offices, schools, etc, and to buy goods from abroad; and only the people of the country can supply the money.One of the most important taxes is income-tax which a person pays according to the amount of his income, whether he is a merchant, a doctor, a lawyer, a shopkeeper, a miner or anything else. This is called a “direct” tax, because it is paid in money directly to the government.Another tax is paid on goods such as watches, jewelry, new clothes, tobacco, wine, etc, when they are brought into a country. Such a tax is paid as part of the price of these goods if they arelate sold in shops. We call it “indirect” tax, because it is paid indirectly through the sho pkeepers. People usually complain about having to pay taxes, but they forget that the money is spent on things that they and their families need. We need policemen to catch thieves, to see that men obey the laws, to direct traffic, etc, and they must be paid what they earn; children need education and there must be schools and teachers; we want our streets to be kept clean, and the wages of men who do this kind of work have to be paid. Above all, the country must always be ready to defend itself against a ttacking enemies, and we can’t have an army without paying for it. Besides, if a country wants to develop, there are many other things to do.Taxes, therefore, cannot be avoided. We buy our food and clothes and pay for our amusements; but, there are several things that the State finds the money for, and that is necessary for us if our society is to continue. We have no real reason to complain, therefore, when we are asked to supply money to be spent for the good of ourselves and for our fellow-citizens.Tax is a 71 part of our lifeWhy mustwe pay taxes?⊕The State need the money for our society to 72 .⊕We supply money for the good of ourselves and 73 .How do we pay taxes?⊕74The tax is paid according to one’s 75 .The tax is paid to the government.⊕76The tax is paid through 77 .The tax is paid as part of the price of goods.Where does tax money go?⊕To 78 —to keep us safe⊕To teachers—to 79⊕To cleaners—to 80⊕To the army—to defend our countrySECTION BDirections: Read the following passage. Answer the questions according to the information given in the passage and the required words limit. Write your answers on your answer sheet.Baloney sausage is a kind of sausage that many Americans eat often. The word baloney also has another meaning in English. It is used to describe something—usually something someone says—that is false or wrong or foolish.Baloney sausage comes from the name of the Italian city, Bologna. The city is famous for its sausage,a mixture of smoked,spiced meat from cows and pigs. But baloney sausage does not taste the same as beef or pork alone.Some language experts think this different taste is responsible for the birth of the expression baloney. The baloney sausage tastes nothing like the meat that is used to make it.Baloney is a word often used by politicians to describe the ideas of their opponents.The expression has been used for years. Fifty years ago,a former governor of New York State, Alfred Smith,criticized some claims by President Franklin Roosevelt about the successes of the Roosevelt administration. Smith said,“No matter how thin you slice it, it is still baloney.”A similar word has almost the same meaning as baloney. It even sounds almost the same. The word is blarney. It began in Ireland about 1600.The lord of Blarney castle,near Cork,agreed to surrender the castle to British troops. But he kept making excuses for delaying the surrender. And,he made them sound like very good excuses,“this is just more of the same blarney.”The Irish castle now is famous for its Blarney stone. Kissing the stone is thought to give a person special powers of speech. One who has kissed the Blarney stone, so the story goes, can speak words of praise so smoothly and sweetly that you believe them, even when you know they are false.81. What does baloney originally mean in this passage? (no more than 4 words)82. Where was Blarney castle? (no more than 2 words)83. According to some experts, what resulted in another meaning of the expression baloney?(no more than 12 words)84.
