He wanted his sons to learn not to judge things too quickly. So he sent them to go and look at a pear tree far away in turns.The first son went in the winter; the second in the spring, the third in summer and the youngest son in the fall.When they had all gone and come back, he called them together to describe what they had seen.The first son said that the tree was ugly. The second son said no; it was covered with green leaves, and full of hope. The third son disagreed. He said there were many flowers that smelled so sweet and looked so beautiful; it was the most wonderful thing he had ever seen. The last son disagreed with all of them; he said there was lots of fruit in the tree, full of life and harvest(收获).The man then explained to his sons that they were all right, but they had each seen only one season in the tree's life. He told them "You cannot judge a tree, or a person by only one season and its true nature—the pleasure, joy, and love that come from that life can only be judged at the end, when all the seasons are up."If you give up when it's winter; you will miss the promise of your spring, the beauty of your summer, harvest of your fall. Don't let the pain of one season kill the joy of all the rest.31.Why did the man ask his sons to go and look at a pear tree in turns? (not more than15 words)32.Did the four sons have the same answer? (not more than 5 words)33.What did the man think about his sons' answers? （not more than 20 words）34.请将文中画线的句子翻译成汉语。

﹣1，），C（z+1，），已知A、B关于原点对称，C在二、四象限平分线上．∴，解得．∴点A的坐标为：（﹣1，﹣3），点B的坐标为：（1，3），点C的坐标为：（2，﹣2）．（2）由点A的坐标为：（﹣1，﹣3），点B的坐标为：（1，3），点C的坐标为：（2，﹣2）．可得A、B、C三点所在的坐标系如下图：（3）如下图所示：∵点A的坐标为：（﹣1，﹣3），点B的坐标为：（1，3），点C的坐标为：（2，﹣2）．∴S△ABC＝S矩形AEFG﹣S△AEC﹣S△CFB﹣S△ABG＝．【点评】本题考查在平面直角坐标系中两点关于原点对称，二四象限角平分线上点的坐标的相关知识，根据各点的坐标可以画出相应的平面之家坐标系，根据三角形各点在平面直角坐标系中的坐标，将△ABC放在矩形AEFG中，从而求出相应三角形的面积．18．（8分）（2019•金台区二模）为了贯彻落实“精准扶贫”精神，某单位决定运送一批物资到某贫困村，货车自早上8时出发，行驶一段路程后发现未带货物清单，便立即以50km/h的速度回返，与此同时单位派车去送清单，途中相遇拿到清单后，货车又立即掉头并开到目的地，整个过程中，货车距离出发地的路程s（km）与行驶时间t（h）的函数图象如图所示．（1）两地相距172千米，当货车司机拿到清单时，距出发地40千米．（2）试求出途中BC段的函数表达式，并计算出中午12点时，货车离贫困村还有多少千米？【分析】（1）依据函数图象中y的最大值可得到两地的距离，用80减去从2小时到2.8小时的路程即可；（2）先求得BC段的速度，然后计算出距离贫困村的距离即可．【解答】解：（1）当t＝5时，y＝172km，所以两地相距172km．80﹣50×（2.8﹣2）＝80﹣40＝40km，所以货车司机拿到清单时，距出发地40千米．故答案为：172；40．（2）设直线BC的解析式为y＝kx+b，∵B（2.8，40），C（5，172），∴，解得，∴直线BC的解析式为y＝60x﹣128．（172﹣40）÷（5﹣2.8）＝60千米/小时．60×1＝60，所以中午12点时，货车离贫困村还有60千米【点评】本题主要考查的是一次函数的应用，读懂函数图象是解题的关键．19．（9分）（2019春•增城区期中）在平面直角坐标系中，O为坐标原点，点A的坐标为（a，﹣a），点B坐标为（b，c），a、b、c满足．（1）若a没有平方根，判断点A在第几象限并说明理由；（2）若点A到y轴的距离是点B到y轴距离的3倍，求点B的坐标；（3）点D的坐标为（2，﹣4），△OAB的面积是△DAB面积的2倍，求点B的坐标．【分析】（1）根据负数没有平方根进行解答即可；（2）解方程组得出关于a的代数式，分两种情况解答即可；（3）根据AB坐标判断线段AB平行于x轴，进而解答即可．【解答】解：（1）∵a没有平方根，∴a＜0，∴﹣a＞0，∴点A（a，﹣a）在第二象限；（2）由方程组，用a表示b，c得b＝﹣a+4，c＝﹣a，再利用点A到y轴的距离是点B到y轴距离的3倍得：|﹣a|＝3|﹣a+4|，可以分两种情况分析：①﹣a＝3（﹣a+4），解之，得a＝6，所以b＝﹣2，c＝﹣6；②﹣a＝﹣3（﹣a+4），解之，得a＝3，所以b＝1，c＝﹣3；综上，B（﹣2，﹣6）或B（1，﹣3）；（3）利用A（a，﹣a）和B（﹣a+4，﹣a），可以判断线段AB平行于x轴．由点D的坐标（2，﹣4），△OAB的面积是△DAB面积的2倍，可以判断点A和点B在x轴的下方，则a＞0，AB•a＝2×AB•|a﹣4|，解得，a＝或a＝8，所以，B（，）或B（﹣4，﹣8）．【点评】本题考查了坐标与图形性质：利用点的坐标计算线段的长和判断线段与坐标轴的位置关系．也考查了三角形的面积公式．20．（10分）（2019秋•锦江区校级期中）如图，直线y＝kx+b与x轴、y轴分别交于点A（4，0）、B（0，4），点P在x轴上运动，连接PB，将△OBP沿直线BP折叠，点O的对应点记为O'．（1）求k、b的值；（2）在x轴上是否存在点C，使得△ABC为等腰三角形？若存在，求出点C的坐标；若不存在，说明理由．（3）若点O′恰好落在直线AB上，求△OBP的面积．【分析】（1）用待定系数法直接求出；（2）分三种情形讨论，①当AB＝AC时，②当BA＝BC时，③当CA＝CB时；分别求出即可；（3）分P在x轴的正半轴和负半轴：①当P在x轴的正半轴时，求OP＝O'P＝AO'＝4﹣4，根据三角形面积公式可得结论；②当P在x轴的负半轴时，同理可得结论．【解答】解：（1）∵点A（4，0）、B（0，4）在直线y＝kx+b上，∴，解得：k＝﹣1，b＝4；（2）存在，理由如下：如图1所示，①当AB＝AC时，AC＝AB＝＝4，可得C1（4﹣4，0），C2（4+4，0）．②当BA＝B时，OA＝OC＝4，可得C3（﹣4，0）．③当CA＝CB时，点C与点O重合，可得C4（0，0），综上所述，满足条件的点C坐标为（4﹣4，0）或（4+4，0）或（﹣4，0）或（0，0）．（3）存在两种情况：①当P在x轴的正半轴上时，如图2所示：点O′恰好落在直线AB上，则OP＝O'P，∠BO'P＝∠BOP＝90°，∵OB＝OA＝4，∴△AOB是等腰直角三角形，∴AB＝4，∠OAB＝45°，由折叠得：∠OBP＝∠O'BP，BP＝BP，∠PO'B＝∠POB＝90°，∴∠PO'A＝90°，∴O'B＝OB＝4，∴AO'＝4﹣4，Rt△PO'A中，O'P＝AO'＝4﹣4＝OP，∴S△OBP＝OB•OP＝×4×（4﹣4）＝8﹣8；②当P在x轴的负半轴时，如图3所示：由折叠得：∠PO'B＝∠POB＝90°，O'B＝OB＝4，∵∠BAO＝45°，∴PO'＝PO＝AO'＝4+4，∴S△OBP＝OB•OP＝×4×（4+4）＝8+8；综上所述，△OBP的面积为8﹣8或8+8．【点评】此题是一次函数综合题，考查了待定系数法、坐标与图形性质、折叠的性质、勾股定理、等腰直角三角形的判定与性质、三角形的面积公式、等腰三角形的性质以及分类讨论等知识；本题综合性强，熟练掌握待定系数法和等腰三角形的性质，进行分类讨论是解题的关键．一，填空题（每题4分，共20分）21．（4分）（2019秋•锦江区校级期中）若xy＝5，x+y＝﹣6，则+＝．【分析】根据有理数的加法法则、乘法法则得到x＜0，y＜0，根据二次根式的混合运算法则把原式化简，代入计算即可．【解答】解：∵xy＝5，x+y＝﹣6，∴x＜0，y＜0，∴+＝﹣﹣＝﹣（+）＝﹣×＝，故答案为：．【点评】本题考查的是二次根式的化简求值，掌握二次根式的混合运算法则是解题的关键．22．（4分）（2019秋•锦江区校级期中）已知关于x的不等式组，只有三个整数解，则实数a的取值范围是﹣2＜a≤﹣1．【分析】先求出不等式组的解集，再根据不等式组有且只有三个整数解求出整数解，得出关于a的不等式组，解得即可．【解答】解；由不等式组得；a≤x＜2，∵只有三个整数解，∴a的取值范围是﹣2＜a≤﹣1，故答案为﹣2＜a≤﹣1．【点评】本题考查了解一元一次不等式组，不等式组的整数解的应用，解此题的关键是能根据已知和不等式组的解集得出关于a的不等式组．23．（4分）（2019春•长宁区期末）我们知道：当x＝2时，不论k取何实数，函数y＝k（x ﹣2）+3的值为3，所以直线y＝k（x﹣2）+3一定经过定点（2，3）；同样，直线y＝（k﹣2）x+3k一定经过的定点为（﹣3，6）．【分析】先将y＝（k﹣2）x+3k化为：y＝（x+3）k﹣2x，可得当x＝﹣3时，不论k取何实数，函数y＝（x+3）k﹣2x的值为6，即可得到直线y＝（k﹣2）x+3k一定经过的定点为（﹣3，6）．【解答】解：根据题意，y＝（k﹣2）x+3k可化为：y＝（x+3）k﹣2x，∴当x＝﹣3时，不论k取何实数，函数y＝（x+3）k﹣2x的值为6，∴直线y＝（k﹣2）x+3k一定经过的定点为（﹣3，6），故答案为：（﹣3，6）．【点评】本题主要考查了一次函数图象上点的坐标特征，直线上任意一点的坐标都满足函数关系式y＝kx+b．24．（4分）（2015•达州）在直角坐标系中，直线y＝x+1与y轴交于点A1，按如图方式作正方形A1B1C1O、A2B2C2C1、A3B3C3C2…，A1、A2、A3…在直线y＝x+1上，点C1、C2、C3…在x轴上，图中阴影部分三角形的面积从左到右依次记为S1、S2、S3、…S

n的值．【解答】方法一：解：∵直线y＝x+1，当x＝0时，y＝1，当y＝0时，x＝﹣1，∴OA1＝1，OD＝1，∴∠ODA1＝45°，∴∠A2A1B1＝45°，∴A2B1＝A1B1＝1，∴S1＝×1×1＝，∵A2B1＝A1B1＝1，∴A2C1＝2＝21，∴S2＝×（21）2＝21同理得：A3C2＝4＝22，…，S3＝×（22）2＝23∴S n＝×（2n﹣1）2＝22n﹣3故答案为：22n﹣3．方法二：∵y＝x+1，正方形A1B1C1O，∴OA1＝OC1＝1，A2C1＝2，B1C1＝1，∴A2B1＝1，S1＝，∵OC2＝1+2＝3，∴A3C2＝4，B2C2＝2，∴A3B2＝2，S2＝2，∴q＝＝4，∴S n＝．【点评】本题考查了一次函数图象上点的坐标特征以及正方形的性质；通过求出第一个正方形、第二个正方形和第三个正方形的边长得出规律是解决问题的关键．25．（4分）（2017秋•姜堰区期中）如图，在平面直角坐标系xOy中，A（0，6），B（4，0），直线l的函数关系式为y＝kx（k＞0），过点A作AP⊥直线l，垂足为P，连接BP，则BP
