2012 年潍坊市初中学业水平考试 数学试题参考答案及评分标准 一.选择题:(本题共 12 小题,共 36 分.在每小题给出的四个选项中,只有一个是正确的,请把正 确的选项选出来,每小题选对得 3 分,选错、不选或选出的答案超过一个,均记零分.) 题号 答案 1 A 2 C 3 B 4 C 5 A 6 D 7 C 8 B 9 D 10 C 11 A 12 D

二.填空题: (本题共 5 小题,共 15 分.只要求填写最后结果,每小题填对得 3 分. ) ?8 13.x(x+2)(x-6) 14、 y ? 15.x=30 x 16.∠BDE=∠BAC 或 BE=BC 或∠ACB=∠DEB 等(写出一个即可.) 18. (本题满分 9 分) (1)证明:因为弧 ED 所对的圆周角相等,所以∠EBD=∠ECD,又因为∠A=∠A,所以 ?ABD ∽
?ACE .

17. n2 .

三.解答题: (本题共 7 小题,共 69 分.解答应写出文字说明、证明过程或演算步骤. )

(2)法 1:因为 S ?BEC ? S ?BCD ,

S ?ACE ? S ?ABC ? S ?BEC , S ?ABD ?S ?ABC?S ?BCD ,

所以 S ?ACE ? S ?ABD ,

又由(1)知 ?ABD ~ ?ACE ,所以对应边之比等于 1, 所以 AB=AC, 即三角形 ABC 为等腰三角形. 法 2:因为 ?BEC 与 ?BCD 的面积相等,有公共底边 BC,所以高相等, 即 E、D 两点到 BC 距离相等,所以 ED∥BC, 所以∠BCE=∠CED, 又因为∠CED=∠CBD, 所以∠BCE=∠CBD, 所以∠ABC=∠ACB 19. (本题满分 9 分) 解: (1)设李明每月存款 x 元,储蓄盒内原有存款 y 元,依题意得, ?2 x ? y ? 80 ? x ? 15 , 解得 ? , ? ?5 x ? y ? 125 ? y ? 50 所以,储蓄盒内原有存款 50 元. (2)由(1)得,李明 2012 年共有存款 12×15+50=230(元) , 2013 年 1 月份后每月存入 15+ t (元) , 2013 年 1 月到 2015 年 6 月共有 30 个月, 依题意得,230+30(15+ t )>1000,
2 解得 t >10 ,所以 t 的最小值为 11. 3

20. (本题满分 10 分) 解: (1)由题意得,在 Rt ?ADC 中, CD 21 ? ? 21 3 =36.33, AD ? ? tan30 3 3 CD 21 在 Rt ?BDC 中, BD ? ? ? 7 3 =12.11, ? tan60 3 所以 AB=AD-BD=36.33-12.11=24.22 ? 24.2(米). (2)汽车从 A 到 B 用时 2 秒,所以速度为 24.2÷2=12.1(米/秒) , 因为 12.1×3600=43560, 所以该车速度为 43.56 千米/小时, 大于 40 千米/小时, 所以此校车在 AB 路段超速. 21.(本题满分 10 分) 解: (1)每人随机取一张牌共有 9 种情况:

所以四边形 AECF 为平行四边形. (2)当 AECF 为菱形时,连结 AC 交 BF 于点 O, 则 AC 与 EF 互相垂直平分, 又 BO=OD, 所以 AC 与 BD 互相垂直平分, 因为 M 是 BC 的中点,AM⊥BC, 所以, ? ABM ≌ ?CAM ,
?ABC 为等边三角形,

所以,四边形 ABCD 是菱形,

所以 AB=BC。

所以,AB=AC,

∠ABC=60°,∠CBD=30°. 在 Rt△BCF 中, CF:BC=tan∠CBF= 所以 AB:AE=

设该家庭以前每月平均用气量为 a 立方米,则由题意得 解得 a =23(立方米) , 即该家庭以前每月平均用气量为 23 立方米. 24. (本题满分 11 分)

50 a ? 10 , 115

解;(1)设抛物线对应二次函数的解析式为 y ? ax2 ? bx ? c ,
1 ? ?a ? 4 ?0 ? 4a ? 2b ? c ? ? 由 ?0 ? 4a ? 2b ? c ,解得 ?b ? 0 , ?? 1 ? c ?c ? ?1 ? ? ? 1 所以 y ? x 2 ? 1 . 4

(2)设 M( x1 , y1 ),N( x2 , y2 ) ,因为点 M、N 在抛物线上, 1 2 1 2 2 所以 y1 ? x1 ? 1 , y2 ? x2 ? 1 ,所以 x2 ? 4( y2 ? 1) ; 4 4
2 2 2 又 ON 2 ? x2 ? y2 ? 4( y2 ? 1) ? y2 ? ( y2 ? 2)2 , 所 以 ON= 2 ? y 2 , 又 因 为 y2 ? ?1 , 所 以

ON= 2 ? y 2 .………5 分 设 ON 的中点 E,分别过点 N、E 向直线 l1 作垂线,垂足为 P、F, OC ? NP 2 ? y 2 ? 则 EF ? , 2 2 所以 ON=2EF, 即 ON 的中点到直线 l1 的距离等于 ON 长度的一半, 所以以 ON 为直径的圆与 l1 相切.…………7 分 (3)过点 M 作 MH⊥NP 交 NP 于点 H,则 MN 2 ? MH 2 ? NH 2 ? ( x2 ? x1 ) 2 ? ( y2 ? y1 ) 2 , 又 y1 ? kx1 , y2 ? kx2 ,所以 ( y2 ? y1 )2 ? k 2 ( x2 ? x1 ) 2 , 所以 MN 2 ? (1 ? k 2 )(x2 ? x1 )2 ,所以 MN ? 1 ? k 2 ( x2 ? x1 ) ; 又因为点 M、N 既在 y ? kx 的图象上又在抛物线上,所以 kx ? 所以 x ?
1 2 x ? 1 ,即 x 2 ? 4kx ? 4 ? 0, 4

4k ? 16k 2 ? 16

所以 MN 2 ? 16 1 ? k 2 ,? MN=4(1+ k 2 ).…………………9 分 延长 NP 交 l 2 于点 Q,过点 M 作 MS⊥ l 2 交 l 2 于点 S, 1 2 1 2 1 2 2 )?2 , 则 MS+NQ= y1 +2+ y2 +2= x1 ? 1 + x2 ? 1 +4= ( x1 ? x2 4 4 4
2 又 x1 ? x2 ? 2[4k 2 ? 4(1 ? k 2 )] ? 16k 2 ? 8 , 2

?

2

2 ? 2k ? 2 1 ? k 2 ,所以 ?x2 ? x1 ? ? 16?1 ? k 2 ? ,

?

2

所以 MS+NQ= 4k 2 ? 2 ? 2 =4(1+ k 2 )=MN. 即 M、N 两点到 l 2 距离之和等于线段 MN 的长.…………………11 分 说明:本参考答案给出了一种解题方法,其它正确方法应参考本标准给出
