B．﹣=6 C．（+）2=5 D．16=4考点：实数的运算；分数指数幂．分析：A、表示81的算术平方根；B、先算﹣6的平方，然后再求的值；C、利用完全平方公式计算即可；D、=．解答：解：A、，故A错误；B、﹣==﹣6，故B错误；C、=2+2+3=5+2，故C错误；D、==4，故D正确．故选：D．点评：本题主要考查的是实数的运算，掌握算术平方根、平方根和二次根式的性质以及完全平方公式是解题的关键．3．如图，要使AD∥BC，那么可以选择下列条件中的（）A．∠1=∠4 B．∠2=∠3 C．∠1+∠B=180°D．∠B=∠D考点：平行线的判定．分析：根据内错角相等两直线平行即可做出选择．解答：解：A、欲证AD∥BC，那可以选择：同位角相等，内错角相等，同旁内角互补，∵∠1和∠4是内错角，且∠1=∠4，∵要使AD∥BC，那么可以选择∠1=∠4．故本选项正确；B、∵∠2=∠3，可以证明AB∥CD，而不能证明AD∥BC，故本选项错误；C、∵∠1和∠B不是同旁内角，故本选项错误；D、∵∠B和∠D不是同位角，也不是内错角，所以不能证明AB∥CD；故选A．点评：此题主要考查学生对平行线的判定这一知识点的理解和掌握，比较简单，属于基础题．4．点P为互相垂直的直线a、b外一点，过点P分别画直线c、d，使c∥a、d⊥a，那么下列判断中正确的是（）A．c∥b B．c∥d C．b⊥c D．b⊥d考点：平行线的判定与性质；垂线．分析：根据题意作出图形后即可得到正确结论．解答：解：根据题意作出如下图形：根据图形知：b⊥c．故选C．点评：本题考查了平行线的性质与判定及垂线的定义，解题的关键是根据题意作出图形，也可以一步步的推导．5．下列说法中，正确的是（）A．两条直线被第三条直线所截，同位角相等B．联结直线外一点到直线上各点的所有线段中，垂线最短C．经过一点，有且只有一条直线与已知直线平行D．经过一点，有且只有一条直线与已知直线垂直考点：命题与定理．分析：分别利用平行线的性质、垂线段最短、平行线的判定以及垂直的判定分析得出即可．解答：解：A、两条平行线被第三条直线所截，同位角相等，错误；B、联结直线外一点到直线上各点的所有线段中，垂线段最短，错误；C、经过直线外一点，有且只有一条直线与已知直线平行，错误；D、经过一点，有且只有一条直线与已知直线垂直，正确；故选D．点评：此题主要考查了命题与定理，正确把握相关定义是解题关键．6．如图，在数轴上表示1、的对应点分别为A、B，B关于点A的对称点为点C，则点C所表示的数是（）A．﹣2 B．2﹣C．﹣1 D．1﹣考点：实数与数轴．分析：首先根据表示1、的对应点分别为点A、点B可以求出线段AB的长度，然后根据点B和点C关于点A对称，求出AC的长度，最后可以计算出点C的坐标．解答：解：∵表示1、的对应点分别为点A、点B，∴AB=﹣1，∵点B关于点A的对称点为点C，∴CA=AB，∴点C的坐标为：1﹣（﹣1）=2﹣．故选B．点评：本题考查的知识点为实数与数轴，解决本题的关键是求数轴上两点间的距离就让右边的数减去左边的数．知道两点间的距离，求较小的数，就用较大的数减去两点间的距离．二、填空题（共14题，每题2分，满分28分）7．16的平方根是±4．考点：平方根．专题：计算题．分析：根据平方根的定义，求数a的平方根，也就是求一个数x，使得x2=a，则x就是a的平方根，由此即可解决问题．解答：解：∵（±4）2=16，∴16的平方根是±4．故答案为：±4．点评：本题考查了平方根的定义．注意一个正数有两个平方根，它们互为相反数；0的平方根是0；负数没有平方根．8．如果a4=81，那么a=3或﹣3．考点：有理数的乘方．分析：根据有理数的开方运算计算即可．解答：解：∵a4=81，∴（a2）2=81，∴a2=9，∴a=3或﹣3．故答案为：3或﹣3．点评：本题考查了有理数的乘方运算的逆运算，解题时注意不用漏解．9．比较大小：﹣2＞﹣3（填“＜”或“=”或“＞”）考点：实数大小比较．分析：根据负数比较大小的法则进行解答即可．解答：解：因为|﹣2|=2≈2.828＜|﹣3|=3，所以：﹣2＞﹣3，故答案为：＞．点评：本题考查的是实数的大小比较，熟知负数比较大小的法则是解答此题的关键．10．计算：8=．考点：分数指数幂．分析：首先把8化成23，然后根据幂的乘方的计算方法，求出算式8的值是多少即可．解答：解：8=（23）==．故答案为：．点评：（1）此题主要考查了分数指数幂问题，要熟练掌握，解答此题的关键是把8化成23．（2）此题还考查了幂的乘方，要熟练掌握，解答此题的关键是要明确：（a m）n=a mn（m，n是正整数）．11．计算：（+2）2013•（﹣2）2013=﹣1．考点：二次根式的混合运算．分析：首先逆用积的乘方公式将原式变形为[（）（）]2013，然后利用平方差公式计算出（）（\sqrt{3}．﹣2）的值，最后再计算乘方即可解答：解：原式=[（）（）]2013=（﹣1）2013=﹣1．点评：本题主要考查的是二次根式的计算，逆用积的乘方公式和平方差公式是解题的关键．12．根据浦东新区2010年第六次全国人口普查公报，浦东新区常住人口为5 044 430人，数字5 044 430可用科学记数法表示为 5.04×106（保留3个有效数字）．考点：科学记数法与有效数字．分析：较大的数保留有效数字需要用科学记数法来表示．用科学记数法保留有效数字，要在标准形式a×10n中a的部分保留，从左边第一个不为0的数字数起，需要保留几位就数几位，然后根据四舍五入的原理进行取舍．解答：解：数据5 044

作直线，与a相交于点M，PM就是所要求作的垂线段；（2）以点P为顶点，画一条直线为一边，作∠P等于这条直线与直线b所成的夹角，则∠P的另一边所在的直线就是所要求作的直线c；（3）根据两直线平行，内错角相等求出∠MNP=∠40°，再根据直角三角形的两锐角互余即可求出∠MPN的度数．解答：解：（1）如图1所示，PM就是所要求作的点P到直线a距离的垂线段；（2）如图2所示，直线c就是所要求作的直线b的平行线；（3）如图3，∵直线a与b的夹角为40°，∴∠PNM=40°，∴∠MPN=90°﹣40°=50°．故答案为：50°．点评：本题考查了过直线外一点作已知直线的垂线，过直线外一点作已知直线的平行线，以及平行线的性质，直角三角形两锐角互余的性质，是小综合题，难度不大，只要细心便不难求解27．如图，已知AB∥CD，∠1=（4x﹣25）°，∠2=（85﹣x）°，求∠1的度数．考点：平行线的性质．专题：探究型．分析：先根据平行线的性质得出∠3的度数，再根据∠1=∠3可知∠1+∠2=180°，把，∠1=（4x﹣25）°，∠2=（85﹣x）°代入求出x的值，进而可得出结论．解答：解：∵AB∥CD，∴∠2+∠3=180°（两直线平行，同旁内角互补）．∵∠1=∠3（对顶角相等）∴∠1+∠2=180°，即（4x﹣25）+（85﹣x）=180，解得x=40．∴∠1=4x﹣25°=135°．点评：本题考查的是平行线的性质，用到的知识点为：两直线平行，同旁内角互补．28．已知：如图，∠A=∠D，∠B=∠C，那么∠1与∠2互补吗？为什么？考点：平行线的判定与性质．分析：首先根据内错角相等得两条直线平行，再根据平行线的性质得内错角相等，运用等量代换的方法得∠AFC=∠D，再根据平行线的判定得两条直线平行，从而根据平行线的性质证明结论．解答：解：∠1与∠2互补．理由如下：∵∠C=∠B，∴AB∥DC，∴∠A=∠AFC，∵∠A=∠D，∴∠AFC=∠D；∴AF∥ED，∴∠1+∠2=180°．点评：此题考查平行线的判定和性质，注意综合运用平行线的性质与判定．2）如图（a），如果∠B+∠E+∠D=360°，那么AB、CD有怎样的关系？为什么？解：过点E作EF∥AB，如图（b），则∠ABE+∠BEF=180°（两直线平行，同旁内角互补）因为∠ABD+∠BED+∠EDC=360°（已知）所以∠FED+∠EDC=180°（等式的性质）所以EF∥CD（同旁内角互补，两直线平行）所以AB∥CD时，∠1，∠2，∠3，∠4满足∠1+∠3=∠2+∠4．考点：平行线的性质．分析：过点E作EF∥AB，由平行线的性质可得出∠ABE+∠BEF=180°，∠ABD+∠BED+∠EDC=360°可得出∠FED+∠EDC=180°，故可得出FE∥CD，由此可得出结论．解答：解：过点E作EF∥AB，如图（b），则∠ABE+∠BEF=180°（两直线平行，同旁内角互补）．因为∠ABD+∠BED+∠EDC=360°（已知），所以∠FED+∠EDC=180°（等式的性质），所以EF∥CD（同旁内角互补，两直线平行），所以AB∥CD时，∠1，∠2，∠3，∠4满足∠1+∠3=∠2+∠4．故答案为：两直线平行，同旁内角互补，180，等式的性质，同旁内角互补，两直线平行，∠1+∠3=∠2+∠4．点评：本题考查的是平行线的性质，用到的知识点为：两直线平行，同旁内角互补．五、综合题（满分6分）30．皓皓同学在学习了“平方根”这节课后知道了“负数在实数范围内没有平方根”，她对这句话产生了兴趣，她想知道负数在其他范围内是否有平方根，所以她上网查找了以下一些资料．数的概念是从实践中产生和发展起来的，在学习了实数以后，像x2=﹣1这样的方程还是没有实数解的，因为没有一个实数的平方等于﹣1，即负数在实数范围内没有平方根，所以为了了解形如x2=﹣1这类方程的解，就要引入一个新的数i．定义：如果一个数的平方等于﹣1，记为i2=﹣1，这个数i叫做虚数单位．在这种情况下，i可以与实数b相乘再同实数a相加从而得到形如“a+bi”（a、b为实数）的数，人们把这种数叫作复数，a叫这个复数的实部，b叫做这个复数的虚部．它的加、减、乘法运算与整式的加、减、乘法运算类似．比如：（1）（2+i）+（4﹣3i）=6﹣2i（2）（i）2=﹣3（3）（5+i）（5﹣i）=52﹣i2=25﹣（﹣1）=26这样数的范围就由实数扩充到了复数，在这种规定下，负数在复数范围内就有平方根．比如：±i就是﹣1的平方根．根据上面的材料解答以下问题：（1）计算：①（2+i）﹣（3﹣2i）=﹣1+3i②i3=﹣i③（3+i）2=8+6i（2）在负数范围内﹣9的平方根是±3i（3）在复数范围内分解因式x4﹣4=（x+）（x﹣）（x+i）（x﹣i）．考点：实数的运算；因式分解的应用．专题：阅读型．分析：（1）①根据合并同类项法则计算即可；②根据积的乘方进行运算，③根据完全平方公式计算；（2）根据平方根的概念计算；（3）根据因式分解的方法进行计算即可．解答：解：（1）①（2+i）﹣（3﹣2i）=2+i﹣3+2i=﹣1+3i，②i3=i2•i=﹣i，③（3+i）2=9+6i+i2=8+6i；（2）±=±3i；（3）x4﹣4=（x2+2）（x2﹣2）=（x+i）（x﹣i）（x﹣）（x+）．故答案为：（1）①﹣1+3i②﹣i③8+6i；（2）±3i；（3）（x+i）（x﹣i）（x﹣）（x+）．点评：本题考查的是实数的运算和因式分解的应用，理解新定义、正确运用因式分解的方法是解题的关键．。

1.95．【考点】实数与数轴．【分析】根据题意可知A点在原点左边，离原点距离为1.2，B点在原点右边，离原点距离为，由此列出算式求AB．【解答】解：依题意，得AB=﹣（﹣1.2）=0.75+1.2=1.95．故答案为：1.95．15．如图，直线a∥c，直线b与直线a、c相交，∠1=∠42°，那么∠2=138°．【考点】平行线的性质．【分析】先根据平行线的性质求出∠1的度数，再由补角的定义即可得出结论．【解答】解：∵直线a∥c，∠1=∠42°，∴∠3=∠1=42°，∴∠2=180°﹣∠3=180°﹣42°=138°．故答案为：138°．16．如图，写出图中∠A所有的内错角：∠ACD，∠ACE．【考点】同位角、内错角、同旁内角．【分析】内错角就是：两个角在截线的两旁，又分别处在被截的两条直线内侧的位置的角．【解答】解：根据内错角的定义，图中∠A所有的内错角：∠ACD，∠ACE．故答案为∠ACD、∠ACE．17．如图，正方形ABCD的面积为5，正方形BEFG面积为4，那么△GCE的面积是﹣2．【考点】正方形的性质；算术平方根．【分析】根据正方形的面积求出两个正方形的边长，然后求出CE，再利用三角形的面积公式列式计算即可得解．【解答】解：∵正方形ABCD的面积为5，正方形BEFG面积为4，∴正方形ABCD的边长为，正方形BEFG的边长为2，∴CE=﹣2，△GCE的面积=CE•BG=×（﹣2）×2=﹣2．故答案为：﹣2．18．如图，要使AD∥BC，需添加一个条件，这个条件可以是∠1=∠4．（只需写出一种情况）【考点】平行线的判定．【分析】根据平行线的判定，可以添加这两条直线被第三条直线所截时的内错角相等，故此题可以添加条件∠1=∠4．【解答】解：可以添加条件∠1=∠4，根据内错角相等，两直线平行可得到AD∥BC．故答案为：∠1=∠4．三、计算：（本大题共4小题，每题5分，满分20分）19．计算：2﹣+．【考点】二次根式的加减法．【分析】直接利用分数加减运算法则合并求出答案．【解答】解：原式=2﹣+=．20．计算：8﹣3×5．【考点】二次根式的混合运算．【分析】直接利用二次根式乘法运算法则化简，进而得出答案．【解答】解：原式=8﹣15×2=﹣22．21．计算：（﹣）2﹣（+）2．【考点】二次根式的混合运算．【分析】先进行完全平方公式的运算，然后合并．【解答】解：原式=3﹣2+2﹣3﹣2﹣2=﹣4．22．利用幂的运算性质进行计算：×3÷（）．【考点】实数的运算；分数指数幂．【分析】原式利用分数指数幂变形后，再利用同底数幂的乘除法则变形，计算即可得到结果．【解答】解：原式=9×3÷27=（9×3÷27）=1．四、（本大题共6题，23、24、25、26、27每小题6分，28题8分，满分38分23．按下列要求画图并填空：（1）如图1，尺规作图：作出△ABC的边AB的垂直平分线，交边AB、AC于点M、N．（2）如图2，过点A画出垂线段AE⊥BC，交直线BC于点E；过点B画出垂线段BF⊥AC，交直线AC于点F．（3）点A到直线BC的距离是线段AE的长．【考点】作图—复杂作图．【分析】（1）分别以A、B为圆心，大于AB的长为半径画弧，两弧交于两点，过两点作直线，交边AB、AC于点M、N，则直线MN即为AB的垂直平分线；（2）利用直角三角尺过点A作AE⊥BC，过点B作BF⊥AC即可；（3）根据点到直线的距离的定义可知点A到直线BC的距离是垂线段AE的长．【解答】解：（1）（2）如图所示：（3）点A到直线BC的距离是线段AE的长．故答案为AE．24．已知：如图，在△ABC中，FG∥EB，∠2=∠3，那么∠EDB+∠DBC等于多少度？为什么？解：因为FG∥EB（已知），所以∠1=∠2 （两直线平行，同位角相等）．因为∠2=∠3（已知），所以∠1=∠3（等量代换）．所以DE∥BC（内错角相等，两直线平行）．所以∠EDB+∠DBC=180°（两直线平行，同旁内角互补）．【考点】平行线的判定与性质．【分析】根据平行线性质推出∠1=∠2，推出∠1=∠3，得出DE∥BC，根据平行线的性质推出即可．【解答】解：∵FG∥BE（已知），∴∠1=∠2（两直线平行，同位角相等），∵∠2=∠3，∴∠1=∠3（等量代换），∴DE∥BC（内错角相等，两直线平行），∴∠EDB+∠DBC=180°（两直线平行，同旁内角互补）．故答案为：已知，两直线平行，同位角相等，等量代换，内错角相等，两直线平行，180°，两直线平行，同旁内角互补．25．如图，已知AB∥CD，∠1=（4x﹣25）°，∠2=（85﹣x）°，求∠1的度数．【考点】平行线的性质．【分析】由AB∥CD，根据两直线平行，同旁内角互补，即可得∠1+∠2=180°，即可得方程（4x﹣25）+（85﹣x）=180，解此方程即可求得答案．【解答】解：∵AB∥CD，∴∠1+∠2=180°（两直线平行，同旁内角互补）．即得（4x﹣25）+（85﹣x）=180，解得：x=40．∴∠1=4x﹣25=135°．26．如图，AB∥DE，CM平分∠BCE，∠MCN=90°，∠B=50°，求∠DCN的度数．【考点】平行线的性质．【分析】先根据AB∥DE得出∠B+∠BCE=180°，进而得出∠BCE的度数，由角平分线的定义得出∠ECM的度数，再根据平角的性质即可得出结论．【解答】解：∵AB∥DE，∴∠B+∠BCE=180°（两直线平行，同旁内角互补）．∵∠B=50°，∴∠BCE=180°﹣50°=130°，∵CM平分∠BCE，∴∠ECM=∠BCE=65°，∵∠MCN=90°，∴∠DCN=180°﹣∠MCN﹣∠ECM=180°﹣90°﹣65°=25°．27．已知：如图，AD∥BE，∠1=∠2，那么∠A=∠E吗？请说明理由．【考点】平行线的判定与性质．【分析】首先根据条件AD∥BE，可证出∠A=∠3，再证明DE∥CB，根据平行线的性质可得∠E=∠3，最后根据等量代换可以得到∠A=∠E．【解答】解：相等，理由：∵AD∥BE，∴∠A=∠3，∵∠1=∠2，∴DE∥BC，∴∠E=∠3，∴∠A=∠E．28．先阅读下列的解答过程，然后再解答：形如的化简，只要我们找到两个正数a、b，使a+b=m，ab=n，使得，，那么便有：（a＞b）例如：化简解：首先把化为，这里m=7，n=12，由于4+3=7，4×3=12即，∴==（1）填空：=，=（2）化简：．【考点】二次根式的化简求值．【分析】由条件对式子进行变形，利用完全平方公式对的形式化简后就可以得出结论了．【解答】解：（1）==，=；=，=，=；故答案为：，（2）原式==，=﹣22016年7月20日。
