Reagan enjoyed a good joke and often made fun of himself. He was very old, almost 70 years of age, when he became President of the USA. Because of this, people often joked about his age. Once, during a meeting, President Reagan was complaining about some reporters who said that he could not hear very well. He wanted to prove that he was healthy and could hear well, so he took out his hearing aid, and said to the people at the meeting, “Say something.” One man pretended to speak. He moved his mouth and made movements with his hands. Everyone thought Reagan would be angry, but he laughed and listened for a very long time.President Reagan not only enjoyed a good joke when he was relaxing, but he also liked to joke during serious situations. In 1981, he had a shot accident. At the hospital, he joked to the doctors that he hoped they supported him in the government and would let him alive. He was试卷第2页,共9页able to keep his sense of humor even when he was hurt. 1、Ronald Reagan was ______in the year 1985. A .a reporter B .an actor C .a doctorD .a president2、The reason why people joked about Reagan's age was that______.

A .His poor hearing. B .His accident. C .His overwork.D .His illness.The Mayan Indians lived in Mexico for thousands of years. The Maya were so bright that they achieved a lot. They had farms, temples and cities with many buildings. They knew much about nature and the world around them. This knowledge helped them to live a better life than most people of that time.In ancient Mexico there were many small clearings in the forest. In each clearing was a village with fields of crops around it. The Maya planted seeds after they cleared the land. A farmer was able to grow crops that produced for several people. But not every Maya had to be a farmer. Some were builders or priests (祭司).The Maya believed in many gods. They built large temples to honor them. Skillful workers built cities around these temples. It was difficult because they had to carry all of the building materials themselves. Today, many of these ancient Mayan cities and temples are still standing. Although the Maya worked hard to build the beautiful cities, very few of them lived in them. Usually, only the priests lived in the cities. The other people lived in small villages in the forests. Their houses were much simpler. Most Maya lived a simple life close to nature.试卷第3页,共9页Around the year 800, the Maya left their villages and beautiful cities, never to return. No one knows why this happened. They may have died from a deadly disease. They may have left because the soil could no longer grow crops. The lost secrets of the Maya are still beyond the reach of modern people. They are still one of our greatest mysteries. 5、The Maya lived better than most people of their times because ______. A .they had skillful workers B .they believed in many gods C .they knew better about nature D .they could measure time correctly6、It can be inferred from the passage that ______.

二、填空题:本大题共5小题,每小题3分,共15分. 16.120 17.318.π3 【解析】由已知,sin α=437,sin(α+β)=5314,可求cos β=cos[(α+β)-α]=12,所以β=π3.19.221320.-5三、解答题:本大题共5小题,共40分.21.【解析】(Ⅰ)证明:f (-x )=log 21+(-x )1-(-x )=log 21-x1+x=log 2⎝ ⎛⎭⎪⎫1+x 1-x -1=-log 21+x1-x =-f (x ), 又x ∈(-1,1),所以函数f (x )是奇函数.(3分) (Ⅱ)设-1<x 1<x 2<1,f (x 2)-f (x 1)=log 21+x 21-x 2-log 21+x 11-x 1=log 2(1-x 1)(1+x 2)(1+x 1)(1-x 2)因为1-x 1>1-x 2>0;1+x 2>1+x 1>0所以(1-x 1)(1+x 2)(1+x 1)(1-x 2)>1,所以log 2(1-x 1)(1+x 2)(1+x 1)(1-x 2)>0所以函数f (x )=log 21+x 1-x在(-1,1)上是增函数.(6分)22.【解析】(Ⅰ)因为是投掷两次,因此基本事件(b ,c )为(1,1),(1,2),(1,3),(1,4),(2,1),(2,2),(2,3),(2,4),(3,1),(3,2),(3,3),(3,4),(4,1),(4,2),(4,3),(4,4),共16个,(1分)当b +c =5时,(b ,c )的所有取值为(1,4),(2,3),(3,2),(4,1),(2分) 所以所求概率为P 1=416=14.(3分)(Ⅱ)①若方程一根为x =1,则1-b -c =0,即b +c =1,不成立.②若方程一根为x =2,则4-2b -c =0,即2b +c =4,所以⎩⎪⎨⎪⎧b =1,c =2.③若方程一根为x =3,则9-3b -c =0,即3b +c =9,所以⎩⎪⎨⎪⎧b =2,c =3.④若方程一根为x =4,则16-4b -c =0,即4b +c =16,所以⎩⎪⎨⎪⎧b =3,c =4.由①②③④知,(b ,c )的所有可能取值为(1,2),(2,3),(3,4),所以方程为“漂亮方程”的概率为P 2=316.(8分)23.【解析】证明:(Ⅰ)∵底面ABCD 是菱形, ∴BD ⊥AC ,∵SA ⊥底面ABCD ,∴BD ⊥SA , ∵SA 与AC 交于A, ∴BD ⊥平面SAC ,∵BD 平面SBD ,∴平面SBD ⊥平面SAC .(4分) (Ⅱ)取SB 中点E ,连接ME ,CE,∵M 为SA 中点,∴ME ∥AB 且ME =12AB ,又∵ABCD 是菱形,N 为CD 的中点, ∴CN ∥AB 且CN =12CD =12AB ,∴CN ∥EM ,且CN =EM,∴四边形CNME 是平行四边形, ∴MN ∥CE ,又MN 平面SBC, CE 平面SBC ,∴直线MN ∥平面SBC .(8分) 24.【解析】(Ⅰ) 依题可得a 2=a 1+2=4,a 3=a 2+2=6, 依题可得{a n }是公差为2的等差数列,∴a n =2n .(2分) (Ⅱ) ∵ S n =n (n +1),∴1S n =1n (n +1)=1n -1n +1,∴T n =⎝ ⎛⎭⎪⎫1-12+⎝ ⎛⎭⎪⎫12-13+…+⎝ ⎛⎭⎪⎫1n -1n +1=1-1n +1<1.(5分)(Ⅲ)依题可得n (n +1)·(n -1)n +4n (n +1)-λ(n +1)(n -1)n ≥0, 即(n -1)n +4-λ(n -1)≥0, 即λ≤n +4n -1对大于1的整数n 恒成立,又n +4n -1=n -1+4n -1+1≥5,当且仅当n =3时,n +4n -1取最小值5, 所以λ的取值范围是(-∞,5].(8分)25.【解析】(Ⅰ)因为圆C 的圆心到直线x +y -2=0的距离为d =|0+0-2|12+12=2,(1分)所以r2=d 2+(82)2=(2)2+42=18.(2分)所以圆C 的方程为x 2+y 2=18.(3分)(Ⅱ)设直线l 与圆C 切于点P (x 0,y 0)(x 0>0,y 0>0),则x 20+y 20=18.(4分) 因为k OP =y 0x 0,所以圆的切线的斜率为-x 0y 0.则切线方程为y -y 0=-x 0y 0(x -x 0),即x 0x +y 0y =18.(5分)则直线l 与x 轴正半轴的交点坐标为⎝ ⎛⎭⎪⎫18x 0,0,与y 轴正半轴的交点坐标为⎝⎛⎭⎪⎫0,18y 0.所以围成的三角形面积为S =12×18x 0×18y 0=162x 0y 0.因为18=x 20+y 20≥2x 0y 0,所以x 0y 0≤9.当且仅当x 0=y 0=3时,等号成立.(8分) 因为x 0>0,y 0>0,所以1x 0y 0≥19,所以S =162x 0y 0≥1629=18.所以当x 0=y 0=3时,S 取得最小值18.所以所求切点P 的坐标为(3,3).(10分) 附加题:(附加题不记入总分)1.【解析】(Ⅰ)设动点坐标为P (x ,y ),则=(x ,y -1),=(x ,y +1),=(1-x ,-y ).因为·=k ||2,所以x 2+y 2-1=k [(x -1)2+y 2],(1-k )x 2+(1-k )y 2+2kx -k -1=0. 若k =1,则方程为x =1,表示过点(1,0)且平行于y 轴的直线.若k ≠1,则方程化为⎝ ⎛⎭⎪⎫x +k 1-k 2+y 2=⎝ ⎛⎭⎪⎫11-k 2,表示以⎝ ⎛⎭⎪⎫k k -1,0为圆心,以1|1-k | 为半径的圆.(Ⅱ)当k =2时,方程化为(x -2)2+y 2=1, 因为2+=(3x ,3y -1),所以|2+|=9x 2+9y 2-6y +1.又x 2+y 2=4x -3,所以|2+|=36x -6y -26. 因为(x -2)2+y 2=1,所以令x =2+cos θ,y =sin θ,则36x -6y -26=637cos(θ+φ)+46∈[46-637,46+637]. 所以|2+|的最大值为46+637=3+37, 最小值为46-637=37-3.2.【解析】(Ⅰ)设等差数列{}a n 的公差为d ,等比数列{}b n 的公比为q , 由题意得,⎩⎪⎨⎪⎧1+d =q 21+5d =q4,解得d =0或3,因数列{}a n ,{}b n 单调递增, 所以d >0,q >1,所以d =3,q =2,所以a n =3n -2,b n =2n -1.因为b 1=a 1,b 3=a 2,b 5=a 6,b 7>a 20,所以c 20=a 17=49.(Ⅱ)设等差数列{}c n 的公差为d ,又a 1=1,且b n =3n ,所以c 1=1,所以c n =dn +1-d . 因为b 1=3是{}c n 中的项,所以设b 1=c n ,即d (n -1)=2.当n ≥4时,解得d =2n -1<1,不满足各项为正整数; 当b 1=c 3=3时,d =1,此时c n =n ,只需取a n =n ,而等比数列{}b n 的项都是等差数列{}a n 中的项,所以S n =12n (n +1); 当b 1=c 2=3时,d =2,此时c n =2n -1,只需取a n =2n -1,由3n =2m -1,得m =3n +12,3n 是奇数,3n +1 是正偶数,m 有正整数解, 所以等比数列{}b n 的项都是等差数列{}a n 中的项,所以S n =n 2.综上所述,数列{}c n 的前n 项和S n =12n (n +1)或S n =n 2.(Ⅲ)存在等差数列{}a n ,只需首项a 1∈(1,q ),公差d =q -1. 下证b n 与b n +1之间数列{}a n 的项数为b n .即证对任意正整数n ,都有⎩⎪⎨⎪⎧b n <ab 1+b 2+…+b n -1+1b n +1>ab 1+b 2+…+b n,即⎩⎪⎨⎪⎧b n <a 1+q +q 2+…+qn -2+1b n +1>a 1+q +q 2+…+qn -1成立. 由b n -a 1+q +q 2+…+qn -2+1=q n -1-a 1-(1+q +q 2+…+q n -2)(q -1)=1-a 1<0, b n +1-a 1+q +q 2+…+qn -1=q n -a 1-(1+q +q 2+…+q n -2+q n -1-1)(q -1)=q -a 1>0. 所以首项a 1∈(1,q ),公差d =q -1的等差数列{}a n 符合题意.。

2017年普通高中学业水平考试模拟试卷二(附中版)物理试题 含解析
2017年湖南省普通高中学业水平考试模拟试卷二(附中版)物理一、选择题:本题包括16小题,每小题3分,共48分.每小题只有一个选项符合题意.1. 下列各组物理量中,全部是矢量的是A。
速度、路程、功率B。
力、位移、加速度C. 功、动能、加速度D. 位移、力、周期【答案】B【解析】速度既有大小又有方向,是矢量,路程、功率只有大小没有方向,都是标量,故A错误;力、位移、加速度既有大小又有方向,都是矢量,故B正确;功、动能只有大小没有方向,都是标量,加速度既有大小又有方向,是矢量,故C错误;位移、力既有大小又有方向,都是矢量,周期只有大小没有方向,是标量,故D错误.所以B 正确,ACD错误.2. 下列说法正确的是A. 伽利略提出了行星运动的三大定律B。
牛顿用实验的方法测出了引力常量C. 胡克认为只有在一定的条件下,弹簧的弹力才与弹簧的形变量成正比D. 开普勒从实验中得出了行星运动的三大定律【答案】C【解析】开普勒提出了行星运动的三大定律,故A错误;卡文迪许用实验的方法测出了引力常量,故B错误;胡克认为只有弹簧的弹性限度内,弹簧的弹力才与弹簧的形变量成正比.故C正确;开普勒在前人的基础上总结得出了行星的三大运动定律,并不是从实验中得到,故D错误。
所以C正确,ABD错误。

下列说法正确的是A. 在不需要考虑物体本身的大小和形状时,用质点来代替物体的方法叫微元法B. 在探究求合力方法的实验中利用了理想模型的方法C。
长度、时间、力是一组属于国际单位制的基本单位的物理量D. 在探究加速度、力和质量三者之间的关系时,先保持质量不变研究加速度与力的关系,再保持力不变研究加速度与质量的关系,该实验应用了控制变量法【答案】D【解析】在不需要考虑物体本身的大小和形状时,用质点来代替物体的方法理想模型法,故A错误;在探究求合力方法的实验中利用了等效替代的方法,故B错误;长度、时间、质量是一组属于国际单位制的基本单位的物理量,故C错误;在探究加速度、力和质量三者之间的关系时,先保持质量不变研究加速度与力的关系,再保持力不变研究加速度与质量的关系,该实验应用了控制变量法,故D正确。
