①2x−6>2 ②，解①得x>2，解②得x>4．故不等式组的解集是x>4．故答案为：x>4．先求出不等式组中每一个不等式的解集，再求出它们的公共部分即可．考查了解一元一次不等式组，一元一次不等式组的解法：解一元一次不等式组时，一般先求出其中各不等式的解集，再求出这些解集的公共部分．解集的规律：同大取大；同小取小；大小小大中间找；大大小小找不到．10.【答案】2(a+2)(a−2)【解析】解：2a2−8=2(a2−4)=2(a+2)(a−2)．故答案为：2(a+2)(a−2)．首先提取公因式2，进而利用平方差公式分解因式即可．此题主要考查了提取公因式法以及公式法分解因式，熟练应用乘法公式是解题关键．11.【答案】14【解析】【分析】此题考查几何概率的求法，事件(A)所表示的区域的面积与总面积的值，就是事件(A)发生的概率．求出黄色区域圆心角在整个圆中所占的比例，这个比例即为所求的概率．【解答】解：∵黄色扇形区域的圆心角为90°，所以黄色区域所占的面积比例为90360=14，即转动圆盘一次，指针停在黄色区域的概率是1，4．故答案为1412.【答案】y=x2+2【解析】解：二次函数y=x2−1的顶点坐标为(0,−1)，把点(0,−1)向上平移3个单位长度所得对应点的坐标为(0,2)，所以平移后的抛物线解析式为y=x2+2．故答案为：y=x2+2．先确定二次函数y=x2−1的顶点坐标为(0,−1)，再根据点平移的规律得到点(0,−1)平移后所得对应点的坐标为(0,2)，然后根据顶点式写出平移后的抛物线解析式．本题考查了二次函数图象与几何变换：由于抛物线平移后的形状不变，故a不变，所以求平移后的抛物线解析式通常可利用两种方法：一是求出原抛物线上任意两点平移后的坐标，利用待定系数法求出解析式；二是只考虑平移后的顶点坐标，即可求出解析式．13.【答案】k<4【解析】【分析】此题考查了一元二次方程ax2+bx+c=0(a≠0)的根的判别式△=b2−4ac：当△>0，方程有两个不相等的实数根；当△=0，方程有两个相等的实数根；当△<0，方程没有实数根．根据判别式的意义得到△=42−4k>0，然后解不等式即可．【解答】解：∵关于x的一元二次方程x2+4x+k=0有两个不相等的实数根，∴△=42−4k>0，解得k<4．故答案为：k<4．14.【答案】y1<y2【解析】【试题解析】，−4<0，解：∵反比例函数y=−4x∴在每个象限内，y随x的增大而增大，∵A(−4,y1)，B(−1,y2)是反比例函数y=−4图象上的两个点，−4<−1，x∴y1<y2．故答案为：y1<y2．根据反比例函数的性质和题目中的函数解析式可以判断y1与y2的大小，从而可以解答本题．本题考查反比例函数图象上点的坐标特征，解答本题的关键是明确反比例函数的性质，利用函数的思想解答．15.【答案】103【解析】解：设圆锥的底面圆半径为r，依题意，得2πr=120π×10，180cm．解得r=103故选：10．3圆锥的底面圆半径为r，根据圆锥的底面圆周长=扇形的弧长，列方程求解．本题考查了圆锥的计算．圆锥的侧面展开图为扇形，计算要体现两个转化：1、圆锥的母线长为扇形的半径，2、圆锥的底面圆周长为扇形的弧长．16.【答案】48【解析】【分析】由图2知，AB=BC=10，当BP⊥AC时，y的值最小，即△ABC中，AC边上的高为8(此时BP=8)，即可求解．本题考查了函数图象的理解和应用，等腰三角形的性质．把图形和图象结合理解得到线段长度是解决本题的关键．【解答】解：根据图象可知点P 在BC 上运动时，此时BP 不断增大，由图象可知：点P 从B 向C 运动时，BP 的最大值为10，即BC =10，由于M 是曲线部分的最低点，∴此时BP 最小，即BP ⊥AC ，BP =8，∴由勾股定理可知：PC =6，由于图象的曲线部分是轴对称图形，∵图象右端点函数值为10，∴AB =BC =10，∴PA =PC =6(三线合一)，∴AC =12，∴△ABC 的面积为：12×12×8=48，故答案为：48． 17.【答案】解：①√8+(3−π)0−(12)−1+tan45°=2√2+1−2+1=2√2；②{x +y =3①3x −5y =4②①×3得：3x +3y =9③，③−②得：8y =5，解得：y =58，把y =58代入①得：x +58=3，解得：x =198，原方程组的解为：{x =198y =58．【解析】①先化简各数，然后再进行计算即可；②利用代入消元法或加减消元法即可解决．本题考查了实数的运算，零指数幂，负整数指数幂，解二元一次方程组，特殊角的三角函数值，学生必须准确熟练掌握才能正确解答．18.【答案】解：(2m+1m −1)÷m2−1m=2m+1−mm⋅m(m+1)(m−1) =m+1m⋅m(m+1)(m−1)=1m−1，当m=√3+1时，原式=1√3+1−1=1√3=√33．【解析】根据分式的减法和除法可以化简题目中的式子，然后将m的值代入即可解答本题．本题考查分式的化简求值，解答本题的关键是明确分式化简求值的方法．19.【答案】解：(1)30；(2)①设D类人数为a，则A类人数为5a，根据题意，得：a+6+12+5a=30，解得：a=2，即A类人数为10、D类人数为2，补全图形如下：②120；③估计大约6月1日这天行走的步数超过10000步的好友人数为150×12+230=70人．【解析】【分析】此题主要考查了条形统计图、扇形统计图的综合运用，读懂统计图，从统计图中得到必要的信息是解决问题的关键.条形统计图能清楚地表示出每个项目的数据．(1)由B类别人数及其所占百分比可得总人数;(2) ①设D类人数为a，则A类人数为5a，根据总人数列方程求得a的值，从而补全图形; ②用360°乘以A类别人数所占比例可得; ③总人数乘以样本中C、D类别人数和所占比例．【解答】解：(1)本次调查的好友人数为6÷20%=30人，故答案为：30；(2)①见答案；②扇形图中，“A”对应扇形的圆心角为360°×1030=120°，故答案为：120；③见答案．20.【答案】解：设原计划平均每天施工x平方米，则实际平均每天施工1.2x平方米，根据题意得：33000x −330001.2x=11，解得：x=500，经检验，x=500是原方程的解，∴1.2x=600．答：实际平均每天施工600平方米．【解析】设原计划平均每天施工x平方米，则实际平均每天施工1.2x平方米，根据时间=工作总量÷工作效率结合提前11天完成任务，即可得出关于x的分式方程，解之即可得出结论．本题考查了分式方程的应用，找准等量关系，正确列出分式方程是解题的关键．21.【答案】解：列表如下：由表可知，共有9种等可能结果，其中抽出的两张卡片上的图案都是“金鱼”的4种结果，所以抽出的两张卡片上的图案都是“金鱼”的概率为49．【解析】列表得出所有等可能结果，然后根据概率公式列式计算即可得解本题考查了列表法和树状图法，用到的知识点为：概率=所求情况数与总情况数之比． 22.【答案】−3<x <−1【解析】解：(1)∵点A(−1,3)在反比例函数y =k x (k 为常数，且k ≠0)的图象上， ∴k =−3，∴反比例函数的解析式为y =−3x ，∵点B(−3,a)在反比例函数图象上，∴a =1，∴点B(−3,1)，设直线AB 的函数关系式y =mx +n ，则{−m +n =3−3m +n =1，解得：{m =1n =4， ∴直线AB 的解析式为y =x +4；(2)由图可知，当−3<x <−1时，一次函数的图象在反比例函数图象上方， ∴当mx +n >k x 时，x 的取值范围为−3<x <−1，故答案为：−3<x <−1．(3)∵直线y =x +4与x 轴交于点C ，且当y =0时，x =−4，∴点C 的坐标为(−4,0)，∴OC =4，点B 到x 轴的距离为1，∴S △BOC =12×4×1=2，∴S △ACP =92S △BOC =9，设点P 的坐标为(a,0)，则CP =|a +4|，∴S △ACP =12×3×|a +4|=32|a +4|=9，解得：a =2或a =−10，∵点P 在x 轴的正半轴上，∴a=2，∴点P的坐标为(2,0)．(1)先由点A求得反比例函数的解析式，然后求得点B的坐标，进而用待定系数法求得直线AB的解析式；(2)观察直线在双曲线上方的部分得到x的取值范围；(3)先求得点C的坐标，然后求得△BOC的面积，然后设点P的坐标为(a,0)，最后根据△ACP和△BOC的面积关系列出方程求得a的值，即可得到点P的坐标．本题考查了反比例函数图象上点的坐标特征、待定系数法求一次函数的解析式、一次函数图象上点的坐标特征，解题的关键是准确设出点P的坐标表示出CP的长．23.【答案】解：过点C作AB的垂线CD，垂足为D，∵AB⊥CD，sin30°=CD，BC=80千米，BC∴CD=BC⋅sin30°=80×1=40(千米)，2=40√2≈56.4(千米)，AC=CDsin45∘∵cos30°=BD，BC=80(千米)，BC∴BD=BC⋅cos30°=80×√3=40√3(千米)，2∵tan45°=CD，CD=40(千米)，AD∴AD=40(千米)，∴AB=AD+BD=40+40√3≈40+40×1.73=109.2(千米)，∴汽车从A地到B地比原来少走多少路程为：AC+BC−AB=136.4−109.2=27.2≈27(千米)．答：汽车从A地到B地比原来少走的路程为27千米．【解析】过点C作AB的垂线CD，垂足为D，在直角△ACD中，解直角三角形求出CD的长度和AC的长度，在直角△CBD中，解直角三角形求出BD的长度，再求出AD的长度，进而求出汽车从A地到B地比原来少走多少路程．本题考查了勾股定理的运用以及解一般三角形的知识，求三角形的边或高的问题一般可以转化为解直角三角形的问题，解决的方法就是作高线．24.【答案】(1)证明：如图，连接OD，∵OD=OA，∴∠ADO=∠OAE，∵AB=BE，∴∠OAE=∠E，∴∠ADO=∠E，∴OD//BE，∵DC⊥BE于点C，∴∠PDO=∠DCB=90°，∵PD经过⊙O的半径OD的端点D，且PD⊥OD，∴PD是⊙O的切线．(2)解：∵∠PDO=90°，∠P=30°，∴∠AOD=60°，∴△OAD是等边三角形，∵∠ODA=∠OAD=60°，∴∠ADP=∠P=30°，∴OA=OD=DA=PA=2，∴OP=4，∴PD=√OP2−OD2=√42−22=2√3，∴S阴影=S△POD−S扇形AOD=12×2√3×2−60×π×22360=2√3−2π3，∴阴影部分的面积为2√3−2π3．【解析】(1)连接OD，由△OAD和△BAE都是等腰三角形可证明∠ADO=∠E，则OD//BE，于是∠PDO=∠DCB=90°，可证明PD是⊙O的切线；(2)先根据∠PDO=90°，∠P=30°求得∠AOD=60°，证明△AOD是等边三角形，可证明OA=OD=DA=PA=2，则OP=4，根据勾股定理求出PD的长，由S阴影=S△POD−S扇形AOD求出阴影部分的面积即可．此题考查圆的切线的判定、等腰三角形的性质、等边三角形的判定与性质、平行线的判定与性质、勾股定理、扇形的面积等知识，此题综合性较强，属于考试压轴题．25.【答案】解：(1)设y 与x 的函数解析式为y =kx +b ，将(10,30)、(16,24)代入，得：{10k +b =3016k +b =24，解得：{k =−1b =40，所以y 与x 的函数解析式为y =−x +40(10≤x ≤16)；(2)根据题意知，W =(x −10)y=(x −10)(−x +40)=−x 2+50x −400=−(x −25)2+225，∵a =−1<0，∴当x <25时，W 随x 的增大而增大，∵10≤x ≤16，∴当x =16时，W 取得最大值，最大值为144，答：每件销售价为16元时，每天的销售利润最大，最大利润是144元．【解析】本题主要考查用待定系数法求一次函数的解析式与二次函数的应用，解题的关键是熟练掌握待定系数法求一次函数解析式及根据相等关系列出二次函数解析式及二次函数的性质．(1)利用待定系数法求解可得y 关于x 的函数解析式；(2)根据“总利润=每件的利润×销售量”可得函数解析式，将其配方成顶点式，利用二次函数的性质进一步求解可得．26.【答案】1 35°【解析】解：(1)如图1中，设BD 交AD 于J ．∵OA=OB，OC=OD，∠AOB=∠COD=35°，∴∠DOB=∠COA，∴△OAC≌△OBD(SAS)，∴AC=BD，∠CAO=∠DBO，∵∠AJM=∠BJO，∴∠AMJ=∠BOJ=35°，∴ACBD=1，∠AMB=35°，故答案为：1，35°．(2)如图2中，结论：ACBD=2，∠AMB=90°．理由：设AO交BM于J．在△OAB和△OCD中，∠AOB=∠COD=90°，tan∠OAB=tan∠OCD=12，∴OBOA =ODOC=12，∵∠COD=∠AOB=90°，∴∠COA=∠DOB，∴△COA∽△DOB，∴ACBD =OCOD=2，∠JAM=∠JBO，∵∠AJM=∠BJO，∴∠AMJ=∠JOB=90°．∴∠AMB=90°．(3)如图3−1中，当点D在线段OA上时，在Rt△AOB中，∠AOB=90°，OB=2√2，OBOA =12，∴OA=4√2，∵OD=√5，∴AD=OA−OD=4√2−√5．如图3−2中，当点D在AO的延长线上时，AD=OA+OD=4√2+√5，综上所述，满足条件的AD的值为4√2−√5或4√2+√5．(1)①如图1中，设BD交AD于J.证明△OAC≌△OBD(SAS)，推出AC=BD，继而得到结论ACBD=1；②证明△OAC≌△OBD(SAS)，推出∠CAO=∠DBO，继而可得结论∠AMJ=∠BOJ=35°；(2)设AO交BM于J.证明△COA∽△DOB，推出ACBD =OCOD=2，∠JAM=∠JBO可得结论．(3)分两种情形：如图3−1中，当点D在线段OA上时，如图3−2中，当点D在AO的延长线上时，解直角三角形求出OA即可解决问题．本题属于几何变换综合题，考查了全等三角形的判定和性质，相似三角形的判定和性质，解直角三角形等知识，解题的关键是正确寻找全等三角形或相似三角形解决问题，学会用分类讨论的思想思考问题，属于中考压轴题．27.【答案】(1,2)【解析】解：(1)令y=0，则−x+3=0，解得x=3，令x =0，则y =3，∴B(3,0)，C(0,3)，将B ，C 的坐标代入抛物线y =ax 2+2x +c 得：{9a +6+c =0c =3，解得：{a =−1c =3， ∴抛物线的解析式为y =−x 2+2x +3；当y =0时，x 1=3，x 2=−1，∴A(−1,0)；(2)①如图，过点M 作ME ⊥x 轴于点E ，∵B(3,0)，C(0,3)，∴∠CBA =45°，∠AMB =90°，∴ME =AE =BE =12AB =2，∴OE =1，∴M(1,2)；故答案为：(1,2)．②∵∠AMQ =90°，∴若四边形AMQP 为平行四边形即可使得四边形AMQP 为矩形，设点P(m,−m 2+2m +3)，∵点A(−1,0)→M(1,2)，∴P(m,−m 2+2m +3)→点Q(m +2,−m 2+2m +5)，将Q 点的坐标代入直线y =−x +3得，−m 2+2m +5=−m −2+3，解得：m 1=4，m 2=−1(舍去)，∴P(4,−5)．(3)∵∠OCB =45°，∴2∠ACB 为钝角，如图，此时∠ANB =2∠ACB ，∵∠ANB=∠ACB+∠CAN，∴∠ACB=∠CAN，∴NC=NA，设N(x,−n+3)，则NC2=n2+(−n+3−3)2=2n2，NA2=(n+1)2+(−n+3)2，∴2n2=(n+1)2+(−n+3)2，解得n=52，∴N(52,1 2).(1)利用直线解析式求出点B、C的坐标，然后利用待定系数法求二次函数解析式解答即可；(2)①可知∠CBA=45°，∠AMB=90°，由等腰直角三角形的性质可得M点的坐标；②由条件可得∠AMQ=90°，若四边形AMQP为平行四边形，则可得四边形AMQP为矩形，由平移规律则可得出点P的坐标；(3)由∠OCB=45°可知2∠ACB为钝角，此时∠ANB=2∠ACB，由外角定理可知∠ACB=∠CAN，由等角对等边可得AN=CN，根据两点间的距离公式可建立等式，求解即可．本题属于二次函数综合题，涉及待定系数法求函数解析式，平行四边形的存在性，坐标系中点的平移，角度存在性等知识，(3)关键是利用平行四边形的性质转化为点的平移；(4)关键是得出AN=CN．。

Children born under Aquarius (Jan. 21st-Feb.19th ) may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn. Scientists believe many of the differences can be explained by the mother’s exposure(暴露) to sunlight in pregnancy(怀孕). Sunlight helps lead to the production of vitamin Din the body. The lack(缺乏) of vitamin D in the first months of life may have a bad effect on health.Vitamin D is called the “sunshine vitamin”. It has a good effect on health. A study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar Studies in the US showed that people born in autumn lived about 160 days longer than those born in spring.Professor Russell Foster said the conclusions were surprising and interesting. He added, “These are small effects but they are very, very clear. I am not giving voice to star signs and they are just for fun. But it is true that we are affected by our season of birth.”( )31. A child’s season of birth can affect all the following things EXCEPT ___________ according to the first two paragraphs.A. his healthB. his heightC. his length of lifeD. his quality of being clever ( )32. What does the underlined word “effect” mean ___________.A. progressB. methodC. matchD. influence( )33. What can we know about vitamin D according to the passage?A. It comes from sunlight.B.
