(2)公平的游戏规则为:数字之和为偶数,小夏获胜;数字之和为奇数,小秋获胜.理由如下:∴数字之和为偶数的可能性为号21,数字之和为奇数的可能性为21,对于双方是公平的. (还有其他设计方法,只要公平,合理即得满分).命题立意:考查概率的意义及求法.21.(本小题满分12分)目前广州市小学和初中在校生共有约128万人,其中小学生在校人教比初中在校人数的2倍多14万人(数据来源:2005学年度广州市教育统计手册). (1)求目前广州市在校的小学生人数和初中生人数;(2)假设今年小学生每人需交杂费500元,初中生每人需交杂费1 000元,而这些费用全部由广州市政府拨款解决,则广州市政府要为此拨款多少?解:(1)设初中生人数为x 人,则小学在校生人数为(2x+14)人.由题意,得x+2x+14=128. 解得x=38. 2x+14=2×38+14=90.所以目前广州市在校的小学生人数为90万人,初中生人数为38万人.(2)广州市政府拨款数=500×90+1 000×38=45 000+38 000=83 000(万元). 所以广州市政府要为此拨款83 000万元. 命题立意:考查列方程(组)解应用题.点评:此题紧扣社会的热点问题,让同学们关心社会热点问题. 22.(本小题满分12分)如图8,⊙O 的半径为1,过点A(2,0)的直线切⊙O 于点B ,交y 轴于点C.图8(1)求线段AB 的长;(2)求以直线AC 为图象的一次函数的解析式. 分析:(1)由于直线AC 是⊙O 的切线,B 为切点,所以需连结OB ,利用切线的性质得OB ⊥AB ,在Rt △AOB 中,利用勾股定理,求出AB 的长.(2)要求直线AC 的解析式,需知A 、C 两点的坐标,设解析式为y=kx+b ,将A 、C 两点代入求出k 、b 的值. 解:(1)连结OB. ∵AB 是⊙O 的切线,B 为切点, ∴AB ⊥OB .在Rt △AOB 中,OA=2,OB=1, ∴AB=3122222=-=-OB OA .(2)∵∠A=∠A ,∠OBA=∠AOC=90°, ∴Rt △AOB ∽Rt △ACO . ∴AOABCO OB =. ∴332321=⨯=∙=AB AO OB OC . ∴C 点的坐标为)332,0(. 设直线AC 的解析式为y=kx+b , 将A(2,0),C )332,0(代入上式得 ⎪⎩⎪⎨⎧==+,332,02b b k ∴⎪⎪⎩⎪⎪⎨⎧=-=.332,33b k∴直线AC 的一次函数解析式为y=33233+-x . 命题立意:考查数形结合思想,点的坐标,与线段长的转化及切线的性质,一次函数解析式的求法.点评:此题是数形结合的典型题目,综合运用了图形与一次函数的主要知识,旨在培养同学们综合运用知识的能力.23.(本小题满分12分)图9是某区部分街道示意图,其中CD 垂直平分AF ,AB ∥CD ,BC ∥DF.从B 站乘车到E 站只有两条路线有直接到达的公交车,路线1是B→D→A→E,路线2是B→C→F→E ,请比较两条路线路程的长短,并给出证明.图9分析:由于路线1的路程为BD+DA+AE ,路线2的路程为BC+CF+FE ,将问题变为比较它们的大小这一数学问题.证明:如图12,延长FD ,交AB 于点G ,图12∵CD ∥AB ,点E 是AF 的中点, ∴点D 是FG 的中点,即FD=DG . ∵CE 垂直平分AF , ∴FD=AD ,AE=FE .① ∵CD ∥AB ,BC ∥DF , ∴四边形BGDG 是平行四边形. ∵BC=DG , ∴BC=FD=AD.② ∵四边形BCFD 是平行四边形, ∴BD=CF .③ 由①②③得BD+DA+AE=BC+CF+FE .所以两条路线路程相等.命题立意:考查线段的垂直平分线的性质,平行四边形判定与性质,中位线等知识. 点评:本题是一个图形在交通方面的应用题,解此类图形应用题的关键是建立合理的数学模型,并利用图形知识来解决这一模型,从而解决实际问题.24.(本小题满分14分)在△ABC 中,AB=BC ,将△ABC 绕点A 沿顺时针方向旋转得到△AB 1C 1,使点C 1落在直线BC 上(点C 1与点C 不重合), (1)如图10,当∠C >60°,写出边AB 1与边CB 的位置关系,并加以证明;(2)当∠C=60°时,写出边AB1与边CB的位置关系(不要求证明);(3)当∠C<60°,请你在图11中用尺规作图法作出△AB1C1(保留作图痕迹,不写作法),再猜想你在(1)、(2)中得出的结论是否成立?并说明理由.图10图11解:(1)AB1∥CB.证明:如图13,由旋转特征知,AC1=AC,△ABC≌△AB1C1.∴∠C=∠AC1.∵AB=BC,∴∠C=∠BAC=∠B1AC1=∠AC1C.∴AB1∥BC.图13(2)AB1∥CB.(3)成立.理由如下:∵AC=AC1,△ABC≌△AB1C1,∴∠C=∠AC1C.∵AB=BC,∴∠C=∠BAC=∠B1AC1=∠AC1C.∴AB1∥BC.命题立意:考查图形的旋转,等腰三角形的性质,平行线的判定.点评:本题实质是考查对图形旋转特征的理解,旋转前后的图形是全等的.25.(本小题满分14分)已知抛物线y=x2+mx-2m2(m≠0).(1)求证:该抛物线与x轴有两个不同的交点:(2)过点P(0,n)作y轴的垂线交该抛物线于点A和点B(点A在点P的左边)是否存在实数m、n,使得AP=2PB?若存在,则求出m、n满足的条件;若不存在,请说明理由.分析:(1)要证抛物线与x轴有两个不同的交点,实际上就是一元二次方程x2+mx-2m2=0有两个不相等的实数根,只要证出b2-4ac>0即可.(2)由题意可知A、B两点的纵坐标为n,代入抛物线解析式找出m、n的关系.(1)证明:∵m2-4×1×(-2m)2=m2+8m2=9m2>0,∴抛物线与x轴有两个不同的交点.(2)解:存在.由题意知:A 、B 两点的纵坐标为n ,代入抛物线的解析式得x 2+mx-2m 2=n , 即x 2+mx-2m 2-n=0. 设A(x 1,n),B(x 2,n), 则|x 1|=2|x 2|,即x 1=±2x 2.①⎪⎩⎪⎨⎧--=∙-=+=.2,,22212121n m x x m x x x x 消去x 1、x 2得92m 2=-2m 2-n ,∴n=(m≠0).②⎪⎩⎪⎨⎧--=∙-=+-=,2,,22212121n m x x m x x x x 消去x 1,x 2,得-2m 2=-2m 2-n , 解得n=0,m≠0的实数. 所以m 、n 满足的条件为n=2920m -(m≠0)或n=0,m≠0的实数. 命题立意:考查二次函数与一元二次方程的关系.点评:此题综合性强,难度较大,解决的关键是将二次函数问题转化为一元二次方程问题,然后求解.。
