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. It helps people live longer.C. Sunlight prevents its production.D. It does harm to people’s health.( )34.Which of the following is TRUE according to the passage?A. Women should get enough sunlight in pregnancy.B. Children born under Aquarius are cleverer than those born in autumn.C. People born in May will live longer than those born in October.D. Professor Russell Foster is interested in star signs and believes in them.( )35. What does the passage mainly tell us?A. People can know the length of life by star signs.B. Women should choose to give birth to children in spring.C. A child’s season of birth has an effect on him or her.D. Vitamin D is not very important to people’s health.V. 用所给词的适当形式填空。

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：．。
