B【解析】need必须，may可能，must一定，必须，should应该；根据句意"约翰尼，你不能玩刀子，你可能会伤到你自己"可知，要填"可能"，其它选项语意不通．故选：B．约翰尼，你不能玩刀子，你可能会伤到你自己．考查情态动词．要根据情态动词的含义和用法，进行比较，找出正确答案．35.【答案】 D【解析】easily容易地，副词，more

1.5；（2）画出将△ABC向左平移4个单位长度后得到的△A1B1C1；（3）以点A为位似中心，在网格内画出△AB2C2，使△AB2C2与△ABC位似，且位似比为3：1．【分析】（1）割补法求解可得；（2）将点A、B、C分别向左平移4个单位得到对应点，再顺次连接可得；（3）利用位似图形的性质得出对应点位置，进而得出答案．解：（1）△ABC的面积为：2×2﹣﹣﹣＝1.5，故答案为：1.5；（2）如图，△A1B1C1为所作；（3）如图，AB2C2为所作．．21．如图，两栋居民楼之间的距离CD＝30m，楼AC和BD均为10层，每层楼高为3m．上午某时刻，太阳光线GB与水平面的夹角为30°．若小明家住在楼AC的4楼，此时他家是否会被遮挡住？请说明理由（参考数据：≈1.732，≈1.414）．【分析】设太阳光线GB交AC于点F，过F作FH⊥BD于H，解直角三角形求出BH≈17，于是得到FC＝HD＝BD﹣BH≈13，可得此刻楼BD的影子会遮挡到楼AC的第5层．解：他家会被遮挡住，理由：设太阳光线GB交AC于点F，过F作FH⊥BD于H，由题意知，AC＝BD＝3×10＝30m，FH＝CD＝30m，∠BFH＝∠α＝30°，在Rt△BFH中，tan∠BFH＝，∴BH＝30×＝10≈10×1.7＝17（米），∴FC＝HD＝BD﹣BH≈30﹣17＝13（米），∵≈4.3，所以在四层的上面，即第五层，答：他家会被遮挡住．22．如图，已知抛物线y＝mx2和直线y＝﹣2x+b都经过点A（﹣2，6），点O为坐标原点，直线y＝﹣2x+b与x轴交于点B．（1）求m、b的值；（2）连接AO，点C是抛物线上一点（异于点A），且S△AOB＝S△COB，求点C的坐标．【分析】（1）根据抛物线y＝mx2和直线y＝﹣2x+b都经过点A（﹣2，6），将A点坐标代入解析式即可求；（2）根据直线y＝﹣2x+2与x轴交于点B，求出点B的坐标，进而求出S△AOB＝S△COB＝3，进而求出点C的纵坐标，代入抛物线解析式可求．解：（1）∵抛物线y＝mx2和直线y＝﹣2x+b都经过点A（﹣2，6），∴6＝（﹣2）2m，6＝﹣2×（﹣2）+b，∴m＝，b＝2；（2）令y＝0，即﹣2x+2＝0，解得x＝1，点B的坐标为（1，0），∴OB＝1，∴S△COB＝S△AOB＝×1×6＝3，∵S△COB＝×1×y c，∴点C的纵坐标为6，当y＝6时，6＝x2，∴x＝±2，∵C是抛物线上一点（异于点A），∴C点的坐标为（2，6）．23．某景区商店销售一种纪念品，这种商品的成本价10元/件，已知销售价不低于成本价，且物价部门规定这种商品的销售价不高于16元/件，市场调查发现，该商品每天的销售量y（件）与销售价x（元/件）之间的函数关系如图所示．（1）求y与x之间的函数关系式，并写出自变量x的取值范围；（2）每件销售价为多少元时，每天的销售利润为125元？【分析】（1）首先利用待定系数法求出一次函数解析式，进而得出答案；（2）根据已知表示出利润，进而解方程得出答案．解：（1）设y与x之间的函数关系式为：y＝kx+b，把（10，30），（16，24）代入得：，解得：．故y与x之间的函数关系式为：y＝﹣x+40（10≤x≤16）；（2）由题意可得：（﹣x+40）（x﹣10）＝125，解得：x1＝15，x2＝35，根据x的范围，只取x＝15．答：每件销售价为15元时，每天的销售利润为125元．24．如图，在△ABC中，AB＝8，BC＝4，CA＝6，CD∥AB，BD是∠ABC的平分线，BD 交AC于点E．（1）求CD的长；（2）求AE的长．【分析】（1）根据题意BD是∠ABC的平分线，可得∠ABE＝∠CBD，又因为CD∥AB，可得∠ABE＝∠BDC，通过等量代换，可知∠CBD＝∠BDC，以求得CD＝BC＝4；（2）由CD∥AB，可得△ABE∽△CDE，从而求出线段比例关系，求得AE＝2EC，因为CA＝AE+EC＝6，可求AE的长度．解：（1）∵BD是∠ABC的平分线，∴∠ABE＝∠CBD，∵CD∥AB，∴∠ABE＝∠BDC，∴∠CBD＝∠BDC，∴CD＝BC＝4，（2）∵CD∥AB，∴△ABE∽△CDE，∴，∴AE＝2EC，∵CA＝AE+EC＝6，∴AE＝4．25．如图是某区域的平面示意图，码头A在观测站B的正东方向，码头A的北偏西60°方向上有一小岛C，小岛C在观测站B的北偏西15°方向上，码头A到小岛C的距离AC 为10海里．（1）填空：∠BAC＝30°，∠C＝45°；（2）求观测站B到码头A的距离（结果保留根号）．【分析】（1）由题意得∠BAC＝90°﹣60°＝30°，∠ABC＝90°+15°＝105°，再由三角形内角和定理即可得出∠C的度数；（2）证出△BCP是等腰直角三角形，得出BP＝PC，再由锐角三角函数定义求出PA＝BP，然后求出BP的长，即可解决问题．解：（1）由题意得：∠BAC＝90°﹣60°＝30°，∠ABC＝90°+15°＝105°，∴∠C＝180°﹣∠BAC﹣∠ABC＝45°，故答案为：30，45；（2）过B作BP⊥AC于P，如图所示：则∠BPC＝∠BPA＝90°，∵∠C＝45°，∴△BCP是等腰直角三角形，∴BP＝PC，∵∠BAC＝30°，∴AB＝2PB，tan∠BAC＝＝，∴PA＝BP，∵PA+PC＝AC，∴BP+BP＝10海里，解得：BP＝（5﹣5）海里，∴AB＝2BP＝（10﹣10）海里，即观测站B到码头A的距离为（10﹣10）海里．26．若一个四边形的一条对角线把四边形分成两个等腰三角形，我们把这条对角线叫做这个四边形的和谐线，这个四边形叫做和谐四边形．（1）如图1，在8×5的网格图上（每个小正方形的边长为1）有一个△ABC，点A、B、C均在格点上，请在网格图中找出2个格点D，使得以A、B、C、D为顶点的四边形是和谐四边形，并画出相应的四边形．（2）如图2，在四边形ABCD中，AB∥CD，∠DAB＝40°，∠B＝80°，AC平分∠DAB．试说明：AC是四边形ABCD的和谐线；（3）已知，在四边形ABCD中，AB＝AD＝BC＝2，∠BAD＝90°，AC是四边形ABCD 的和谐线，直接写出CD的长2或2．【分析】（1）根据和谐四边形的定义，作出图形即可．（2）证明DA＝DC，AC＝AB，即可．（3）首先根据题意画出图形，然后由AC是四边形ABCD的和谐线，可以得出△ACD是等腰三角形，从图3，图4两种情况运用等边三角形的性质，正方形的性质和30°的直角三角形性质就可以得出结论．【解答】（1）解：如图，四边形ABDC即为所求．（2）证明：如图2中，∵AC平分∠DAB，∴∠DAC＝∠CAB＝∠DAB＝20°，∵CD∥AB，∴∠DCA＝∠CAB＝20°，∴∠DAC＝∠DCA，∴DA＝DC，∵∠ACB＝180°﹣∠CAB﹣∠B＝180°﹣20°﹣80°＝80°，∴∠ACB＝∠B，∴AC＝AB，∴AC是四边形ABCD的和谐线．（3）如图3，4，∵AC是四边形ABCD的和谐线，∴△ACD是等腰三角形．∵AB＝AD＝BC，如图3，当AD＝AC时，∴AB＝AC＝BC，∠ACD＝∠ADC，∴△ABC是正三角形，∴∠BAC＝∠BCA＝60°．∵∠BAD＝90°，∴∠CAD＝30°，过点C作CE⊥AD于E，∴CE＝AC＝1，∴AE＝，∴DE＝AD﹣AE＝2﹣，∴CD＝＝2如图4，当AD＝CD时，CD＝2，综上所述，满足条件的CD的长为2或2．27．如图1，矩形OABC顶点B的坐标为（6，2），定点D的坐标为（9，0），动点P从点O出发，以每秒2个单位长度的速度沿x轴的正方向匀速运动，动点Q从点D出发，以每秒1个单位长度的速度沿x轴的负方向匀速运动，P、Q两点同时运动，相遇时停止，在运动过程中，以PQ为斜边在x轴上方作等腰直角三角形PQR．设运动时间为t秒．（1）当t＝1时，△PQR的边QR经过点B，当t＝时，点R落在边BC上；（2）设△PQR和矩形OABC重叠部分的面积为S，求S与t的函数关系式；（3）如图2，过定点E（4，0）作EF⊥BC，垂足为F，当△PQR的顶点R落在矩形OABC 的内部时，过点R作x轴、y轴的平行线，分别交EF、BC于点M、N，若∠MAN＝45°，直接写出t的值．【分析】（1）△PQR的边QR经过点B时，△ABQ构成等腰直角三角形，则有AB＝AQ，由此列方程求出t即可，当R落在BC边上时，因为△PQR是等腰直角三角形，故PR＝AB，由此列出方程求解即可；（2）在图形运动过程中分三种情况讨论，按t的取值范围分段写出关系式即可；（3）首先判定四边形ABFE是正方形，其次通过旋转，由三角形全等证明MN＝EN+BN，设EM＝m，BN＝n，在Rt△FMN中，有勾股定理得出m和n的关系式，由此等式列方程求出t的值即可．解：（1）△PQR的边QR经过点B时，△ABQ构成等腰直角三角形，∴AB＝AQ，即2＝9﹣6﹣t，解得t＝1，∴t＝1时，△PQR的边QR经过点B；点R落在边BC上，则R纵坐标的长度和AB相同，∵△PQR为等腰直角三角形，∴PQ＝2AB＝2×2＝4，即9﹣t﹣2t＝4，解得t＝，∴t＝时，点R落在边BC上；故答案为：1，；（2）①当0≤t≤1时，如图1所示，设PR交BC于点G，过点P作PH⊥BC于点H，则CH＝OP＝2t，GH＝PH＝2，∴S＝S矩形OABC﹣S梯形OPGC＝6×2﹣（2t+2t+2）×2＝10﹣4t；②当1＜t≤时，如图2所示，设PR交BC于点C，RQ交BC、AB于点S、T，过点P作PH⊥BC于点H，则CH＝OP＝2t，GH＝HP＝2，QD＝t，则AQ＝AT＝9﹣6﹣t＝3﹣t，∴BT＝BS＝AB﹣AT＝2﹣（3﹣t）＝t﹣1，∴S＝S矩形OABC﹣S梯形OPGC﹣S△BST＝6×2﹣﹣（2t+2t+2）×2﹣（t﹣1）2＝﹣t2﹣3t+；③当＜t≤3时，如图3所示，设RQ与AB交于点T，则AT＝AQ＝9﹣6﹣t＝3﹣t，PQ＝9﹣2t﹣t＝9﹣3t，∴PR＝RQ＝PQ＝（9﹣3t），∴S＝S△PQR﹣S△AQT＝PR2﹣AQ2＝[（9﹣3t）]2﹣（3﹣t）2＝t2﹣t+；综上，S与t的函数关系式为；（3）∵E（4，0），∴AE＝AB＝2，∴四边形ABFE是正方形，如图4，将△AME绕A顺时针旋转90°，得到△ABM'，其中AE和AB重合，∵∠MAN＝45°，∴∠EAM+∠NAB＝45°，∴∠BAM'+∠NAB＝45°，∴∠MAN＝∠M'AN，连接MN，在△MAN和△M'AN中，，∴△MAN≌△M'AN（SAS），∴MN＝M'N＝M'B+BN，∴MN＝EM+BN，设EM＝m，BN＝n，则FM＝2﹣m，FN＝2﹣n，在Rt△FMN中，由勾股定理得：FM2+FN2＝MN2，即（2﹣m）2+（2﹣n）2＝（m+n）2，整理得，mn+（m+n）﹣4＝0，①延长NR交x轴于点S，则m＝EM＝RS＝PQ＝×（9﹣3t），∵QS＝PQ＝×（9﹣3t），AQ＝3﹣t，∴n＝BN＝AS＝QS﹣AQ＝×（9﹣3t）﹣（3﹣t）＝﹣，∴m＝3n，代入①式，化简得：3n2+4n﹣4＝0，解得n＝或n＝﹣2（舍去），∴BN＝﹣＝，解得t＝，故答案为：．。
