满分100分，时间90分钟。
第Ⅰ卷(选择题共40分)一、选择题(共10小题，每小题4分，共40分，在每小题给出的四个选项中，第1～6小题只有一个选项符合题目要求，第7～10小题有多个选项符合题目要求，全部选对的得4分，选不全的得2分，有选错或不答的得0分) 1．如图，执行任务的“歼20”战机正沿直线斜向下加速俯冲。
将“歼20”简化为质点“O”，用G表示它受到的重力，F表示除重力外其他作用力的等效力，则下图中能正确表示此过程中战机受力情况的是(A)解析：执行任务的“歼20”战机正沿直线斜向下加速俯冲，则所受的合力方向应该和运动方向在同一直线上，否则就要做曲线运动。
2．(2021·北京朝阳区高一期末)如图所示，在注满清水的竖直密封玻璃管中，红蜡块R正以较小的速度v0沿y轴匀速上浮，与此同时玻璃管沿水平x轴正方向做匀速直线运动。
从红蜡块通过坐标原点O开始计时，直至蜡块运动到玻璃管顶端为止。
在此过程中，下列说法正确的是(A)A．红蜡块做匀速直线运动B．红蜡块做变速曲线运动C．红蜡块的速度与时间成正比D．仅增大玻璃管运动的速度，红蜡块将更快运动到顶端解析：两个匀速直线运动的合运动还是匀速直线运动，则红蜡块做匀速直线运动，所以A正确B错误；红蜡块做匀速直线运动，红蜡块的速度保持不变，所以C错误；根据运动的独立性原理，水平方向的运动不会影响竖直方向的运动，则仅增大玻璃管运动的速度，红蜡块运动到顶端的时间不变，所以D错误。
3．(2021·石家庄市高一上学期期末)“套圈”是老少皆宜的游戏。
如图所示，将A、B、C三个套圈分别以速度v1、v2、v3水平抛出，都能套中地面上的同一玩具，已知套圈A、B抛出时距玩具的水平距离相等，套圈A、C抛出时在同一高度，设套圈A、B、C在空中运动时间分别为t1、t2、t3。

一、选择题(本大题共12个小题，每小题5分，共60分，在每小题给出的四个选项中只有一个是符合题目要求的)1．(2012·湖北卷)已知某几何体的三视图如图所示，则该几何体的体积为( )A .8π3B ．3πC .10π3D ．6π[命题意图] 本题考察空间几何体的三视图． [答案] B[解析] 显然有三视图我们易知原几何体为一个圆柱体的一部分，并且有正视图知是一个1/2的圆柱体，底面圆的半径为1，圆柱体的高为6，则知所求几何体体积为原体积的一半为3π.选B .2．已知正方体外接球的体积是323π，那么正方体的棱长等于( ) A ．2 2 B .223 C .423 D .433[答案] D[解析] 设正方体的棱长为a ，球的半径为R ，则43πR 3＝323π，∴R ＝2.又∵3a ＝2R ＝4，∴a ＝433.3．直线x －2y ＋1＝0关于直线x ＝1对称的直线方程是( ) A ．x ＋2y －1＝0 B ．2x ＋y －1＝0 C ．2x ＋y －3＝0 D ．x ＋2y －3＝0[答案] D[解析] 在所求直线上任取一点P(x ，y)，则点P 关于直线x ＝1的对称点为P ′(2－x ，y)，且P ′在直线x －2y ＋1＝0上，即2－x －2y ＋1＝0，整理得x ＋2y －3＝0，故选D .4．在空间直角坐标系中，O 为坐标原点，设A(12，12，12)，B(12，12，0)，C(13，13，13)，则( )A．OA⊥AB B．AB⊥AC C．AC⊥BC D．OB⊥OC [答案]C[解析]|AB|＝12，|AC|＝36，|BC|＝66，因为|AC|2＋|BC|2＝|AB|2，所以AC⊥BC.5．若P(2，－1)为圆(x－1)2＋y2＝25的弦AB的中点，则直线AB 的方程为()A．x－y－3＝0 B．2x＋y－3＝0C．x＋y－1＝0 D．2x－y－5＝0[答案]A[解析]设圆(x－1)2＋y2＝25的圆心为C(1,0)，则AB⊥CP，∵k CP＝－1，∴k AB＝1，∴y＋1＝x－2，即x－y－3＝0，故选A.6．已知m，n是两条不同直线，α，β，γ是三个不同平面，下列命题中正确的是()A．若m∥α，n∥α，则m∥nB．若α⊥γ，β⊥γ，则α∥βC．若m∥α，m∥β，则α∥βD．若m⊥α，n⊥α，则m∥n[答案]D[解析]A中还可能m，n相交或异面，所以A不正确；B、C中还可能α，β相交，所以B、C不正确．很明显D正确．7．如图，在长方体ABCD－A1B1C1D1中，M，N分别是棱BB1，B1C1的中点，若∠CMN＝90°，则异面直线AD1和DM所成角为()A．30°B．45°C．60°D．90°[答案]D[解析]因为MN⊥DC，MN⊥MC，所以MN⊥平面DCM.所以MN⊥DM.因为MN∥AD1，所以AD1⊥DM.8．(2012－2013·山东济宁模拟)已知直线l过点(－2,0)，当直线l 与圆x2＋y2＝2x有两个交点时，其斜率k的取值范围是() A．(－22，22) B．(－2，2)C．(－24，24) D．(－18，18)[答案]C[解析]设直线l的斜率为k，则l的方程为y＝k(x＋2)，即kx－y＋2k＝0，由于l与圆x2＋y2＝2x有两个交点，则需满足圆心到直线的距离d＝|3k|k2＋1＜1，解得－24＜k＜24.9．在三棱柱ABC－A1B1C1中，各棱长相等，侧棱垂直于底面，点D是侧面BB1C1C的中心，则AD与平面BB1C1C所成角的大小是()A．30°B．45°C．60°D．90°[答案] C[解析] 过A 作AE ⊥BC 于点E ，则易知AE ⊥面BB 1C 1C ，则∠ADE 即为所求，又tan ∠ADE ＝AEDE ＝3，故∠ADE ＝60°.故选C .10．过点M(－2,4)作圆C ：(x －2)2＋(y －1)2＝25的切线l ，且直线l 1：ax ＋3y ＋2a ＝0与l 平行，则l 1与l 间的距离是( )A .85B .25 C .285 D .125[答案] D[解析] 因为点M(－2,4)在圆C 上，所以切线l 的方程为(－2－2)(x －2)＋(4－1)(y －1)＝25，即4x －3y ＋20＝0.因为直线l 与直线l 1平行， 所以－a 3＝43，即a ＝－4，所以直线l 1的方程是－4x ＋3y －8＝0，即4x －3y ＋8＝0.所以直线l 1与直线l 间的距离为|20－8|42＋(－3)2＝125.故选D .11．点P(4，－2)与圆x 2＋y 2＝4上任一点连线的中点轨迹方程是( )A ．(x －2)2＋(y ＋1)2＝1B ．(x －2)2＋(y －1)2＝4C ．(x －4)2＋(y －2)2＝1D ．(x －2)2＋(y －1)2＝1 [答案] A[解析] 设圆上任意一点为(x 1，y 1)，中点为(x ，y)，则⎩⎨⎧x ＝x 1＋42y ＝y 1－22，⎩⎪⎨⎪⎧x 1＝2x －4y 1＝2y ＋2，代入x 2＋y 2＝4，得(2x －4)2＋(2y ＋2)2＝4，化简得(x －2)2＋(y ＋1)2＝1.12．设P(x ，y)是圆x 2＋(y ＋4)2＝4上任意一点，则(x －1)2＋(y －1)2的最小值为( ) A .26＋2 B .26－2 C ．5 D ．6[答案] B[解析] 如图，设A(1,1)，(x －1)2＋(y －1)2 ＝|PA|，则|PA|的最小值为|AC|－r ＝26－2.三、填空题(本大题共4小题，每小题5分，共20分)13．顺次连结A(1,0)，B(1,4)，C(3,4)，D(5,0)所得到的四边形绕y 轴旋转一周，所得旋转体的体积是________．[答案] 184π3[解析] 所得旋转体的上底、下底分别为3,5，高为4的圆台，去掉一个半径为1，高为4的圆柱．V 台＝13(9π＋9π×25π＋25π)×4＝196π3，V 柱＝4π，则V ＝V 台－V 柱＝184π3.14．经过点P(1,2)的直线，且使A(2,3)，B(0，－5)到它的距离相等的直线方程为________．[答案] 4x －y －2＝0或x ＝1[解析] x ＝1显然符合条件；当A(2,3)，B(0，－5)在所求直线同侧时，所求直线与AB 平行，∵k AB ＝4，∴y －2＝4(x －1)， 即4x －y －2＝0.15．圆x 2＋y 2＋Dx ＋Ey ＋F ＝0关于直线l 1：x －y ＋4＝0与直线l 2：x ＋3y ＝0都对称，则D ＝________，E ＝________.[答案] 6 －2[解析] 由题设知直线l 1，l 2的交点为已知圆的圆心．由⎩⎪⎨⎪⎧ x －y ＋4＝0，x ＋3y ＝0，得⎩⎪⎨⎪⎧x ＝－3，y ＝1，所以－D 2＝－3，D ＝6，－E2＝1，E ＝－2.16．已知圆C 过点(1,0)，且圆心在x 轴的正半轴上，直线l ：y ＝x －1被圆C 所截得的弦长为22，则过圆心且与直线l 垂直的直线的方程为________．[答案] x ＋y －3＝0 [解析] 设圆心(a,0)(a ＞0)， ∴(|a －1|2)2＋(2)2＝|a －1|2.∴a ＝3.∴圆心(3,0)．∴所求直线方程为x＋y－3＝0.四、解答题(本大题共6小题，共70分，解答应写出文字说明，证明过程或演算步骤)17．(本小题满分10分)(2011·课标全国高考，文18)如图，四棱锥P－ABCD中，底面ABCD为平行四边形，∠DAB＝60°，AB＝2AD，PD⊥底面ABCD.(1)证明PA⊥BD；(2)设PD＝AD＝1，求棱锥D－PBC的高．[解析](1)证明：因为∠DAB＝60°，AB＝2AD，由余弦定理得BD＝3AD.从而BD2＋AD2＝AB2，故BD⊥AD.又PD⊥底面ABCD，可得BD⊥PD.所以BD⊥平面PAD.故PA⊥BD.(2)如图，作DE⊥PB，垂足为E.已知PD⊥底面ABCD，则PD⊥BC.由(1)知BD⊥AD，又BC∥AD，所以BC⊥BD.故BC⊥平面PBD，所以BC⊥DE.则DE⊥平面PBC.由题设知PD＝1，则BD＝3，PB＝2.根据DE·PB＝PD·BD，得DE＝3 2，即棱锥D－PBC的高为3 2.18．(本小题满分12分)如图，矩形ABCD的两条对角线相交于点M(2,0)，AB边所在直线的方程为x－3y－6＝0，点T(－1,1)在AD边所在直线上．(1)求AD 边所在直线的方程； (2)求矩形ABCD 外接圆的方程．[解析] (1)因为AB 边所在直线的方程为x －3y －6＝0，且AD 与AB 垂直，所以直线AD 的斜率为－3.又因为点T(－1,1)在直线AD 上，所以AD 边所在直线的方程为y －1＝－3(x ＋1)，即3x ＋y ＋2＝0.(2)由⎩⎪⎨⎪⎧x －3y －6＝03x ＋y ＋2＝0，解得点A 的坐标为(0，－2)．因为矩形ABCD两条对角线的交点为M(2,0)，所以M 为矩形ABCD 外接圆的圆心．又r ＝|AM|＝(2－0)2＋(0＋2)2＝2 2.所以矩形ABCD 外接圆的方程为(x －2)2＋y 2＝8.19．(本小题满分12分)已知圆的半径为10，圆心在直线y ＝2x 上，圆被直线x －y ＝0截得的弦长为42，求圆的方程．[解析] 方法一：设圆的方程是(x －a)2＋(y －b)2＝10.因为圆心在直线y ＝2x 上，所以b ＝2a. ①解方程组⎩⎪⎨⎪⎧x －y ＝0，(x －a )2＋(y －b )2＝10， 得2x 2－2(a ＋b)x ＋a 2＋b 2－10＝0， 所以x 1＋x 2＝a ＋b ，x 1·x 2＝a 2＋b 2－102.由弦长公式得2·(a ＋b )2－2(a 2＋b 2－10)＝42，化简得(a －b)2＝4. ②解①②组成的方程组，得a ＝2，b ＝4，或a ＝－2，b ＝－4.故所求圆的方程是(x －2)2＋(y －4)2＝10，或(x ＋2)2＋(y ＋4)2＝10.方法二：设圆的方程为(x －a)2＋(y －b)2＝10，则圆心为(a ，b)，半径r ＝10，圆心(a ，b)到直线x －y ＝0的距离d ＝|a －b|2. 由弦长、弦心距、半径组成的直角三角形得d 2＋(422)2＝r 2，即(a －b )22＋8＝10，所以(a －b)2＝4.又因为b ＝2a ，所以a ＝2，b ＝4，或a ＝－2，b ＝－4.故所求圆的方程是(x －2)2＋(y －4)2＝10，或(x ＋2)2＋(y ＋4)2＝10.20．(本小题满分12分)(2012·山东卷)如图，几何体E－ABCD是四棱锥，△ABD为正三角形，CB＝CD，EC⊥BD.(1)求证：BE＝DE；(2)若∠BCD＝120°，M为线段AE的中点，求证：DM∥平面BEC.[解析](1)设BD中点为O，连接OC，OE，则由BC＝CD知，CO⊥BD，又已知CE⊥BD，所以BD⊥平面OCE.所以BD⊥OE，即OE是BD的垂直平分线，所以BE＝DE.(2)取AB中点N，连接MN，DN，∵M 是AE 的中点，∴MN ∥BE ，∵△ABD 是等边三角形，∴DN ⊥AB.由∠BCD ＝120°知，∠CBD ＝30°，所以∠ABC ＝60°＋30°＝90°，即BC ⊥AB ，所以ND ∥BC ，所以平面MND ∥平面BEC ，故DM ∥平面BEC.21．(本小题满分12分)在平面直角坐标系xOy 中，已知圆C 1：(x－4)2＋(y －5)2＝4和圆C 2：(x ＋3)2＋(y －1)2＝4.(1)若直线l 1过点A(2,0)，且与圆C 1相切，求直线l 1的方程；(2)直线l 2的方程是x ＝52，证明：直线l 1上存在点P ，满足过P 的无穷多对互相垂直的直线l 3和l 4，它们分别与圆C 1和圆C 2相交，且直线l 3被圆C 1截得的弦长与直线l 4被圆C 2截得的弦长相等．[解析] (1)若直线斜率不存在，x ＝2符合题意；当直线l 1的斜率存在时，设直线l 1的方程为y ＝k(x －2)，即kx －y －2k ＝0， 由条件得|4k －5－2k|k 2＋1＝2， 解得k ＝2120， 所以直线l 1的方程为x ＝2或y ＝2120(x －2)，即x ＝2或21x －20y －42＝0.(2)由题意知，直线l 3，l 4的斜率存在，设直线l 3的斜率为k ，则直线l 4的斜率为－1k ，设点P 坐标为(52，n)，互相垂直的直线l 3，l 4的方程分别为：y －n＝k(x －52)，y －n ＝－1k (x －52)，即kx －y ＋n －52k ＝0，－1k x －y ＋n ＋52k ＝0，根据直线l 3被圆C 1截得的弦长与直线l 4被圆C 2截得的弦长相等，两圆半径相等．由垂径定理得：圆心C 1到直线l 3与圆心C 2到直线l 4的距离相等． 故有⎪⎪⎪⎪⎪⎪4k －5＋n －52k k 2＋1＝⎪⎪⎪⎪⎪⎪3k－1＋n ＋52k 1k 2＋1， 化简得(52－n)k ＝212－n 或(12＋n)k ＝－n －12＝－(12＋n)．关于k 的方程有无穷多解，有12＋n ＝0，即n ＝－12，即直线l 2上满足条件的点P 是存在的，坐标是(52，－12)．22．(本小题满分12分)(2013·全国高考卷Ⅱ文科18题)如图已知三棱柱ABC －A 1B 1C 1中，D 、E 分别是AB 、BB 1的中点．(1)证明：BC1∥面A1CD1；(2)设AA1＝AC＝CB＝2，AB＝22，求三棱锥C－A1DE的体积．[解析](1)连结AC1交A1C于点F，则F为AC1的中点，又D是AB中点，连结DF，则BC1∥DF，因为DF⊂平面A1CD，BC1⊄平面A1CD，所以BC1∥平面A1CD.(2)因为ABC－A1B1C1是直三棱柱，所以AA1⊥CD，由已知AC ＝CB，D为AB中点，所以，CD⊥AB，又AA1∩AB＝A，于是CD⊥平面ABB1A1，由AA1＝AC＝CB＝2，AB＝22得，∠ACB＝90°，CD＝2，A1D＝6，DE＝3，A1E＝3，故A1D2＋DE2＝A1E2，即DE⊥A1D，所以VC－A1DE＝13×12×6×3×2＝1.。
