m,则题意得:,整理得:x2﹣6x+4=0,故答案为:x2﹣6x+4=015.【解答】解:连接AE,过点F作FH⊥AE,∵六边形ABCDEF是正六边形,∴AB=BC=CD=DE=EF=a,∠AFE=∠DEF=120°,∴∠F AE=∠FEA=30°,∴∠AEP=90°,∴FH=,∴AH=,AE=,∵P是ED的中点,∴EP=,∴AP=.∴=16.【解答】解:如图,连接OC,延长AO交⊙O于F,连接DF.∵四边形ACDO是平行四边形,∴∠DOF=∠A,DO=AC,∵OF=AO,∴△DOF≌△CAO,∴DF=OC,∴点D的运动轨迹是F为圆心OC为半径的圆,∴当点D在BF的延长线上时,BD的值最大,∵∠AOB=108°,∴∠FOB=72°,∵OF=OB,∴∠OFB=54°,∵FD=FO,∴∠FOD=∠FDO=27°,∴∠A=∠FOD=27°,故答案为27°.三、解答题(本大题共8题,共72分,解答应写出文字说明、证明过程或演算步骤.)17.【解答】解:(1)2x2﹣3x+1=0(x﹣1)(2x﹣1)=0x﹣1=0或2x﹣1=0解得x1=1,x2=.(2)(x+1)2+2x(x+1)=0(x+1)(x+1+2x)=0x+1=0,3x+1=0,∴x1=﹣1,x2=﹣.18.【解答】解:原式=[+]•=•=,∵a是方程x2+3x+1=0的根,∴a2+3a+1=0,即a2+3a=﹣1,则原式=﹣.19.【解答】(1)证明:连接OC.∵CD是⊙O的切线,∴∠OCD=90°,∵∠AEC=90°,∴∠OCD=∠AEC,∴AE∥OC,∴∠EAC=∠ACO,∵OA=OC,∴∠OAC=∠OCA,∴∠EAC=∠OAC,∴AC平分∠DAE.(2)作CF⊥AB于F.在Rt△OCD中,∵OC=3,OD=5,∴CD=4,∵•OC•CD=•OD•CF,∴CF=,∵AC平分∠DAE,CE⊥AE,CF⊥AD,∴CE=CF=.20.【解答】解:(1)①线段CD如图所示;②当AB=BC时,四边形ABCD是菱形,此时C(﹣4,6),原来点C坐标(﹣4,8),∴线段CD向下平移2个单位时,四边形ABCD为菱形;故答案为2.(2)由题意AB=5,当P A=PB=时,四边形ABCD是正方形,∴(a)2+(﹣a﹣3)2=()2,解得a=﹣或(舍弃)∴当a=﹣时,四边形ABCD为正方形.故答案为﹣.21.【解答】解:(1)如图所示:所有等可能结果为(红、绿、红)、(红、绿、绿)、(红、绿、红)、(红、绿、绿)、(红、红、红)、(红、红、绿),(绿、绿、红)、(绿、绿、绿)、(绿、绿、红)、(绿、绿、绿)(绿、红、红)、(绿、红、绿)这12种等可能结果;(2)因为“取出至少一个红球”的结果数为10钟,所以“取出至少一个红球”的概率为=.22.【解答】解:(1)根据题意知,y==﹣x+;(2)根据题意,得:(﹣x+)x=384,解得:x=18或x=32,∵墙的长度为24m,∴x=18;(3)设菜园的面积是S,则S=(﹣x+)x=﹣x2+x=﹣(x﹣25)2+∵﹣<0,∴当x<25时,S随x的增大而增大,∵x≤24,∴当x=24时,S取得最大值,最大值为416,答:菜园的最大面积为416m2.23.【解答】解:(1)∵双曲线y=经过点D(6,1),∴=1,解得k=6;(2)设点C到BD的距离为h,∵点D的坐标为(6,1),DB⊥y轴,∴BD=6,∴S△BCD=×6•h=12,解得h=4,∵点C是双曲线第三象限上的动点,点D的纵坐标为1,∴点C的纵坐标为1﹣4=﹣3,∴=﹣3,解得x=﹣2,∴点C的坐标为(﹣2,﹣3),设直线CD的解析式为y=kx+b,则,解得,所以,直线CD的解析式为y=x﹣2;(3)AB∥CD.理由如下:∵CA⊥x轴,DB⊥y轴,设点C的坐标为(c,),点D的坐标为(6,1),∴点A、B的坐标分别为A(c,0),B(0,1),设直线AB的解析式为y=mx+n,则,解得,所以,直线AB的解析式为y=﹣x+1,设直线CD的解析式为y=ex+f,则,解得,∴直线CD的解析式为y=﹣x+,∵AB、CD的解析式k都等于﹣,∴AB与CD的位置关系是AB∥CD.24.【解答】解:(1)∵四边形ABCD为矩形,∴∠A=∠D=90°,∴∠AEP+∠APE=90°,∵PE⊥PC,∴∠APE+∠CPD=90°,∴∠AEP=∠DPC,∴△P AE∽△CDP;(2)∵AP=x,BE=y,∴DP=3﹣x,AE=2﹣y.∵△P AE∽△CDP,∴,即,∴.∵,∴当时,y有最小值,y的最小值为,又∵点E在AB上运动(显然点E与点A不重合),且AB=2,∴y<2.综上所述,BE的取值范围是≤BE<2;(3)存在,理由如下:如图,假设存在这样的点Q,使得QC⊥QE,由(1)得:△P AE∽△CDP,∴,∴AP•DP=AE•DC,∵QC⊥QE,∠D=90°,∴∠AQE+∠DQC=90°,∠DQC+∠DCQ=90°,∴∠AQE=∠DCQ.又∵∠A=∠D=90°,∴△QAE∽△CDQ,∴,∴AQ•DQ=AE•DC,∴AQ•DQ=AP•DP,即AQ•(3﹣AQ)=AP•(3﹣AP),∴3AQ﹣AQ2=3AP﹣AP2,∴AP2﹣AQ2=3AP﹣3AQ,∴(AP+AQ)(AP﹣AQ)=3(AP﹣AQ).∵AP≠AQ,∴AP+AQ=3.又∵AP≠AQ,∴AP≠,即P不能是AD的中点,∴当P是AD的中点时,满足条件的Q点不存在,故当P不是AD的中点时,总存在这样的点Q满足条件,此时AP+AQ=3.25.【解答】解:(1)∵抛物线y=ax2+2x+c与x轴交于A(﹣1,0)、B(3,0)两点,∴,解得.所以,抛物线的解析式为y=﹣x2+2x+3;(2)∵抛物线上的点C(m,n),∴n=﹣m2+2m+3,当m=3时,n=0,∴C(3,0),∴一次函数y=kx+b的图象l经过抛物线上的点C(m,n),∴3k+b=0,∴b=﹣3k,∴一次函数的解析式为y=kx﹣3k,∵直线l与抛物线只有一个公共点,∴方程kx﹣3k=﹣x2+2x+3有两个相等的实数根,∴(k﹣2)2+4(3k+3)=0,解得k=﹣4;(3)如图,过C点作CH⊥PD于H,C(m,n)在直线y=kx+b上,∴n=(﹣2m+2)m+b,∵点C在抛物线上,∴n=﹣m2+2m+3,∴b=m2+3,∴直线l为y=(﹣2m+2)x+m2+3,∵直线l与抛物线的对称轴相交于点D,∴D的横坐标为1,代入得:y=﹣2m+2+m2+3=8﹣(﹣m2+2m+3)=8﹣n,∴D(1,8﹣n),设P(1,p),则PD=8﹣n﹣p,HC=m﹣1,PH=p﹣n,在Rt△PCH中,PC=PD=8﹣n﹣p,∴(8﹣n﹣p)2=(p﹣n)2+(m﹣1)2∴(8﹣n﹣p)2﹣(p﹣n)2=(m﹣1)2,∴(8﹣2n)(8﹣2p)=m2﹣2m+1,∵n=﹣m2+2m+3,∴2(4﹣n)(8﹣2p)=4﹣n,∵k=﹣2m+2≠0,∴m≠1,∴n≠4,∴4﹣n≠0,∴2(8﹣2p)=1,∴p=,∴P(1,).。

( A )One day I visited an art museum while waiting for my husband to finish a business meeting. I was looking forward to a quiet view of the art works.A young couple viewing the painting ahead of me chatted nonstop between themselves. I watched them a moment and decided the wife was doing all the talk. I admired the husband’s patience for putting up with her continuous talk. Annoyed by their noise, I moved on.I saw them several more times as I moved through the different rooms. Each time I heard her talk and talk, I moved away quickly.I was standing at the counter of the museum gift shop when the couple came towards the exit. Before they left, the man reached into his pocket and pulled out a white object. He pulled it into a long stick and then tapped his way into the coatroom to get his wif e’s jacket.“He’s a brave man,” the clerk at the counter said. “Most of us would give up if we were blinded at such a young age. During his recovery, he made a promise that his life wouldn’t change. So, as before, he and his wife come in whenever there is a new art show.”“But what does he get out of the art?” I asked. “He can’t see.”“Can’t see? You’re wrong. He sees a lot. More than you and I do,” the clerk said.“His wife describes each painting so he can see it in his mind.”I learned something about patience, courage and love that day.

In 1917 he joined the army and was sent to Alabama. There he met his future wife Zelda Sayre. Then he decided to make some money to impress her.His life with her was full of great happiness, as he wrote in h is diary: “My own happiness in the past often approached such joy that I could share it even with the person dearest to me but had to walk it away in quiet streets and take down parts of it in my diary.”This side of paradise, his first novel, was published in 1920. Encouraged by its success, Fitzgerald began to devote more time to his writing. Then he continued with the novel the Beautiful and Damned (1922), a collection of short stories Thales of the Jazz Age (1922), and a play The Vegetable (1923). But his greatest success was The Great Gatsby, published in 1925, which quickly brought him praise from the literary world. Yet it failed to give him the needed financial security. Then, in 1926, he published another collection of short stories All the Sad Young Men.However, Fitzgerald’s problems with his wife Zelda affected his writing.
