2020-2021学年七年级数学下学期期末测试卷【人教版03】数学（答案卷）一．选择题（共12小题，满分48分，每小题4分）1．（4分）的相反数是（）A．B．C．D．【分析】直接利用相反数的定义得出答案．【解答】解：﹣2的相反数是：﹣（﹣2）＝2﹣．故选：A．2．（4分）（﹣7）2的算术平方根是（）A．7B．±7C．﹣49D．49【分析】先求出式子的结果，再根据算术平方根的定义求出即可．【解答】解：∵（﹣7）2＝49，＝7，∴（﹣7）2的算术平方根是7，故选：A．3．（4分）据科学家统计，目前地球上已经被定义、命名的生物约有1500万种左右，数字1500万用科学记数法表示为（）A．1.5×103B．1.5×106C．1.5×107D．15×106【分析】科学记数法的表示形式为a×10n的形式，其中1≤|a|＜10，n为整数．确定n的值时，要看把原数变成a时，小数点移动了多少位，n的绝对值与小数点移动的位数相同．当原数绝对值≥10时，n 是正整数；当原数的绝对值＜1时，n是负整数．【解答】解：1500万＝15000000＝1.5×107．故选：C．4．（4分）下列各式正确的是（）A．B．（﹣3）2＝9C．﹣22＝4D．＝2【分析】根据平方根、立方根的意义计算．【解答】解：A.＝2，故A错误，不符合题意；B．（﹣3）2＝9，故B正确，符合题意；C．﹣22＝﹣4，故C错误，不符合题意；D.＝﹣2，故D错误，不符合题意；故选：B．5．（4分）如图，已知直线AB∥CD，点F为直线AB上一点，G为射线BD上一点．若∠HDG＝2∠CDH，∠GBE＝2∠EBF，HD交BE于点E，则∠E的度数为（）A．45°B．55°C．60°D．无法确定【分析】设∠CDH＝x，∠EBF＝y，得到∠HDG＝2x，∠DBE＝2y，根据平行线的性质得到∠ABD＝∠CDG＝3x，求得x+y＝60°，根据三角形的内角和即可得到结论．【解答】解：∵∠HDG＝2∠CDH，∠GBE＝2∠EBF，∴设∠CDH＝x，∠EBF＝y，∴∠HDG＝2x，∠DBE＝2y，∵AB∥CD，∴∠ABD＝∠CDG＝3x，∵∠ABD+∠DBE+∠EBF＝180°，∴3x+2y+y＝180°，∴x+y＝60°，∵∠BDE＝∠HDG＝2x，∴∠E＝180°﹣2x﹣2y＝180°﹣2（x+y）＝60°，故选：C．6．（4分）已知是二元一次方程mx+3y＝7的一组解，则m的值为（）A．﹣2B．2C．﹣D．【分析】把x与y的值代入方程计算，即可求出m的值．【解答】解：把代入方程得：﹣m+9＝7，解得：m＝2．故选：B．7．（4分）不等式组的解集在数轴上表示正确的是（）A．B．C．D．【分析】分别求出每一个不等式的解集，结合各选项中解集在数轴上的表示即可．【解答】解：解不等式﹣2x+5≥3，得：x≤1，解不等式3（x﹣1）＜2x，得：x＜3，故选：B．8．（4分）甲、乙两种品牌的方便面在2016～2020年销售增长率如图所示，下列说法一定正确的是（）A．这几年内甲、乙两种品牌的方便面销售量都在逐步上升B．甲品牌方便面在2018年到2019年期间销售量在下降C．在2017到2018年期间，甲品牌方便面销售量高于乙品牌D．根据折线统计图的变化趋势，预测在2020～2021年期间，甲品牌的销售量高于乙品牌【分析】根据折线统计图可直接解答．【解答】解：从折线图来看：乙种品牌的方便面销售量呈上升趋势，甲种品牌的方便面销售量不稳定，有上升有下降，故A错误，不符合题意；甲品牌方便面在2018年到2019年期间只是增长率下降，不能得出销售量在下降，故B错误，不符合题意；在2017到2018年期间，甲品牌方便面销售量高于乙品牌，C正确，符合题意；根据折线统计图的变化趋势，不能预测在2020～2021年期间，甲品牌的销售量高于乙品牌，故D错误，不符合题意．故选：C．9．（4分）下列命题：①过一点有且只有一条直线与已知直线平行；②垂直于同一条直线的两条直线互相平行；③相等的角是对顶角；④平行于同一条直线的两条直线互相平行．其中是真命题有（）A．1个B．2个C．3个D．4个【分析】根据平行公理、平行线的判定定理、对顶角的概念判断即可．【解答】解：①过直线外一点有且只有一条直线与已知直线平行，故本小题说法是假命题；②在同一平面内，垂直于同一条直线的两条直线互相平行，故本小题说法是假命题；③相等的角不一定是对顶角，故本小题说法是假命题；④平行于同一条直线的两条直线互相平行，本小题说法是真命题；故选：A．10．（4分）已知x＞y，xy＜0，a为任意有理数，下列式子一定正确的是（）A．﹣x＞﹣y B．a2x＞a2y C．﹣x+a＜﹣y+a D．x＞﹣y【分析】根据已知求出x＞0，y＜0，再根据不等式的性质逐个判断即可．【解答】解：∵x＞y且xy＜0，∴x＞0，y＜0，∴A、﹣x＜﹣y，故本选项不符合题意；B、当a＝0时，a2x＝a2y，即a2x＞a2y错误，故本选项不符合题意；C、∵x＞y，∴﹣x＜﹣y，∴﹣x+a＜﹣y+a，故本选项符合题意；D、根据题意不能判断x和﹣y的大小，故本选项不符合题意；故选：C．11．（4分）如图，把一张长方形纸条折叠成如图所示的形状，若已知∠2＝65°，则∠1为（）A．130°B．115°C．100°D．120°【分析】先根据翻折变换的性质求出∠3的度数，再由平行线的性质即可得出结论．【解答】解：∵∠2＝65°，∴∠3＝180°﹣2∠2＝180°﹣2×65°＝50°，∵矩形的两边互相平行，∴∠1＝180°﹣∠3＝180°﹣50°＝130°．故选：A．12．（4分）为庆祝建党100周年，更加深入了解党的光荣历史，我校团委计划组织全校共青团员到曾家岩周公馆、红岩村纪念馆、烈士墓渣滓洞一线开展红色研学之旅．计划统一乘车前往，若调配30座客车若干辆，则有8人没有座位；若调配36座客车，则用车数量将减少1辆，并空出4个座位．设计划调配30座客车x辆，全校共青团员共有y人，则根据题意可列出方程组为（）A．B．C．D．【分析】根据“调配30座客车若干辆，则有8人没有座位；若调配36座客车，则用车数量将减少1辆，并空出4个座位”列出方程即可．【解答】解：设计划调配30座客车x辆，全校共青团员共有y人，根据题意得：，故选：A．二．填空题（共4小题，满分16分，每小题4分）13．（4分）比较大小：＜6﹣（填“＞”“＜”或“＝”）．【分析】分别判断出、6﹣与4的大小关系，即可判断出、6﹣的大小关系．【解答】解：∵＜，＝4，∴＜4；∵6﹣＞6﹣2＝4，∴＜6﹣．故答案为：＜．14．（4分）若关于x、y的方程组的解满足x+y＝2k，则k的值为﹣．【分析】根据等式的性质，可得答案．【解答】解：②+①，得2x+2y＝2k﹣3，∴x+y＝k﹣，∵关于x，y的方程组的解满足x+y＝2k，∴2k＝k﹣，解得k＝﹣．故答案为：﹣．15．（4分）若关于x的不等式组．只有4个整数解，则a的取值范围是．【分析】先解不等式组得到2﹣3a＜x＜21，再利用不等式组只有4个整数解，则x只能取17、18、19、20，所以16≤2﹣3a＜17，然后解关于a的不等式组即可．【解答】解：，解①得x＜2，解②得1x＞2﹣3a，所以不等式组的解集为2﹣3a＜x＜21，因为不等式组只有4个整数解，所以16≤2﹣3a＜17，所以﹣5＜a≤﹣．故答案为：﹣5＜a≤﹣．16．（4分）如图，平面直角坐标系中O是原点，等边△OAB的顶点A的坐标是（2，0），动点P从点O出发，以每秒1个单位长度的速度，沿O→A→B→O→A…的路线作循环运动，则第2021秒时，点P的坐标是（，）．【分析】计算前面7秒结束时的各点坐标，得出规律，再按规律进行解答便可．【解答】解：由题意得，第1秒结束时P点的坐标为P1（1，0）；第2秒结束时P点的坐标为P2（2，0）；第3秒结束时P点的坐标为P3（2﹣1×cos60°，1×sin60°），即P3（，）；第4秒结束时P点的坐标为P4（1，2×sin60°），即P4（1，）；第5秒结束时P点的坐标为P5（，）；第6秒结束时P点的坐标为P6（0，0）；第7秒结束时P点的坐标为P7（1，0），与P1相同；……由上可知，P点的坐标按每6秒进行循环，∵2021÷6＝336……5，∴第2021秒结束后，点P的坐标与P5相同为（，），故答案为：（，）．三．解答题（共8小题，满分86分）17．（8分）（1）计算；（2）解方程组．【分析】（1）利用实数混合运算的法则计算即可；（2）利用代入法可解．【解答】解：（1）原式＝9+（﹣3）+2+2﹣＝10﹣；（2）．①+②得：20x+20y＝60．∴x+y＝3 ③．由③得：y＝3﹣x④，把④代入①得：11x+9（3﹣x）＝36．解得：x＝4.5．把x＝4.5代入④得：y＝﹣1.5．∴原方程组的解为：．18．（8分）按要求解下列不等式（组）．（1）解关于x的不等式1﹣≤，并将解集用数轴表示出来．（2）解不等式组，将解集用数轴表示出来，并写出它的所有整数解．【分析】（1）去分母，去括号，移项，合并同类项，系数化成1即可；（2）先求出每个不等式的解集，再求出不等式组的解集即可．【解答】解：（1）1﹣≤，去分母得：6﹣2（2x﹣1）≤3（1+x），去括号得：6﹣4x+2≤3+3x，移项得：﹣4x﹣3x≤3﹣6﹣2，合并同类项得：﹣7x≤﹣5，系数化成1得：x≥，在数轴上表示为：；（2），解不等式①得：x≤1，解不等式②得：x＞﹣3，所以不等式组的解集是﹣3＜x≤1，在数轴上表示不等式组的解集为：，所以不等式组的整数解是﹣2，﹣1，0，1．19．（10分）已知：3a+21的立方根是3，4a﹣b﹣1的算术平方根是2，c的平方根是它本身．（1）求a，b，c的值；（2）求3a+10b+c的平方根．【分析】（1）根据立方根，算术平方根，平方根的概念即可求出答案；（2）根据（1）中所求a、b、c的值代入代数式3a+10b+c中即可求出答案．【解答】解：（1）根据题意可知，3a+21＝27，解得a＝2，4a﹣b﹣1＝4，解得b＝3，c＝0，所以a＝2，b＝3，c＝0；（2）因为3a+10b+c＝3×2+10×3+0＝36，36的平方根为±6．所以3a+10b+c的平方根为±6．20．（10分）填空，完成下列证明过程，并在括号中注明理由．如图，已知∠BEF+∠EFD＝180°，∠AEG ＝∠HFD，求证：∠G＝∠H．证明：∵∠BEF+∠EFD＝180°，（已知）．∴AB∥CD（同旁内角互补，两直线平行）．∴∠AEF＝∠EFD（两直线平行，内错角相等）．又∵∠AEG＝∠HFD，∴∠AEF﹣∠AEG＝∠EFD﹣∠HFD，即∠GEF＝∠HFE．∴EG∥FH（内错角相等，两直线平行）．∴∠G＝∠H．（两直线平行，内错角相等）．【分析】根据平行线的判定得出AB∥CD，根据平行线的性质得出∠AEF＝∠EFD，求出∠GEF＝∠HFE，根据平行线的判定推出EG∥FH，根据平行线的性质得出答案即可．【解答】证明：∵∠BEF+∠EFD＝180°（已知），∴AB∥CD（同旁内角互补，两直线平行），∴∠AEF＝∠EFD（两直线平行，内错角相等），又∵∠AEG＝∠HFD，∴∠AEF﹣∠AEG＝∠EFD﹣∠HFD，即∠GEF＝∠HFE，∴EG∥FH（内错角相等，两直线平行），∴∠G＝∠H（两直线平行，内错角相等），故答案为：已知，CD，同旁内角互补，两直线平行，∠AEF，两直线平行，内错角相等，∠GEF，∠HFE，EG，内错角相等，两直线平行，两直线平行，内错角相等．21．（12分）为了解某市市民对“垃圾分类知识”的知晓程度．某数学学习兴趣小组对市民进行随机抽样的问卷调查．调查结果分为“A．非常了解”，“B．了解”，“C．基本了解”，“D．不太了解”四个等级进行统计，并将统计结果绘制成如图两幅不完整的统计图（图1，图2）．请根据图中的信息解答下列问题：（1）这次调查的市民人数为1000人，图2中，n＝35；（2）补全图1中的条形统计图，并求在图2中“A．非常了解”所在扇形的圆心角度数；（3）据统计，2020年该市约有市民900万人，那么根据抽样调查的结果，可估计对“垃圾分类知识”的知晓程度为“D．不太了解”的市民约有多少万人？据此，请你提出一个提升市民对“垃圾分类知识”知晓程度的办法．【分析】（1）从条形、扇形统计图中可以得到“C组”有200人，占调查总人数的20%，可求出调查人数；计算出“A组”所占的百分比，进而可求“B组”所占的百分比，确定n的值；（2）计算出“B组”的人数，即可补全条形统计图；“A．非常了解”所占整体的28%，其所对应的圆心角就占360°的28%，求出360°×28%即可；（3）样本中“D．不太了解”的占17%，估计全市900万人中，也有17%的人“不太了解”．【解答】解：（1）这次调查的市民人数为：200÷20%＝1000（人）；∵m%＝×100%＝28%，n%＝1﹣20%﹣17%﹣28%＝35%∴n＝35；故答案为：1000，35；（2）B等级的人数是：1000×35%＝350（人），补全统计图如图所示：“A．非常了解”所在扇形的圆心角度数为：360°×28%＝100.8°；（3）根据题意得：“D．不太了解”的市民约有：900×17%＝153（万人），提升市民对“垃圾分类知识”知晓程度的办法：市民通过网络等渠道增加对垃圾分类的了解，理解垃圾分类的重要意义．答：“D．不太了解”的市民约有153万人．提升市民对“垃圾分类知识”知晓程度的办法：市民通过网络等渠道增加对垃圾分类的了解，理解垃圾分类的重要意义．22．（12分）如图，△ABC的三个顶点坐标为：A（﹣3，1），B（1，﹣2），C（2，2），△ABC内有一点P
