58【解析】解：测量可得，图中A，B两点之间的距离是2厘米（精确到厘米），点B在点A 的南偏西58°（精确到度）．故答案为：2，58．根据长度的测量可求图中A，B两点之间的距离；根据方向角的定义可求点B 的方向．考查了两点间的距离，关键是熟练掌握长度和角的测量方法．13.【答案】答案不唯一，如：2x3【解析】解：可以写成：2x3+xy-5，故答案为：2x3．根据多项式的次数定义进行填写，答案不唯一，可以是2x3，3x3等．本题考查了多项式的定义和次数，明确如果一个多项式含有a个单项式，次数是b，那么这个多项式就叫b次a项式．14.【答案】4b-2a【解析】解：剩余白色长方形的长为b，宽为（b-a），所以剩余白色长方形的周长=2b+2（b-a）=4b-2a．故答案为4b-2a．利用矩形的性质得到剩余白色长方形的长为b，宽为（b-a），然后计算它的周长．本题考查了矩形的性质：平行四边形的性质矩形都具有；矩形的四个角都是直角；邻边垂直；矩形的对角线相等；15.【答案】∠COD，∠EOF【解析】解：∵射线OD平分∠COA，∴∠COD=∠1．∵∠DOF=∠AOE=90°，∴∠DOE+∠EOF=90°，∠DOE+∠1=90°，∴∠EOF=∠1．∴图中与∠1相等的角有∠COD，∠EOF．故答案为∠COD，∠EOF．根据角平分线定义可得∠COD=∠1；根据同角的余角相等可得∠EOF=∠1．本题考查了余角和补角，角平分线定义，掌握余角的性质是解题的关键．16.【答案】（2x-700）+x=5900【解析】解：设珐琅书签的销售了x件，则文创笔记本销售了（2x-700）件，根据题意得：（2x-700）+x=5900．故答案为：（2x-700）+x=5900．设珐琅书签的销售了x件，则文创笔记本销售了（2x-700）件，根据文创笔记本和珐琅书签共销售5900件，即可得出关于x的一元一次方程，此题得解．本题考查了由实际问题抽象出一元一次方程，找准等量关系，正确列出一元一次方程是解题的关键．17.【答案】-2或18【解析】解：∵AO=10，∴点A表示的数为±10，∵AB=8，且点A表示的数比点B表示的数小，∴点B表示的数是-2或18，故答案为：-2或18根据AO=10，得到点A表示的数为±10，由AB=8，且点A表示的数比点B表示的数小，得到点B表示的数在点A表示的数的右边，于是得到结论．本题考查了数轴，正确的理解题意是解题的关键．18.【答案】-2 2【解析】解：（1）（2x-1）+3+ax=2x-1+3+ax=（2+a）x+2，∵当三个滚珠同时相撞时，不论输入x的值为多大，输出y的值总不变，∴2+a=0，得a=-2，故答案为：-2；（2）当y=2x-1+3=2x+2时，令y=-1，则-1=2x+2，得x=-1.5（舍去），当y=3+（-2x）=-2x+3时，令y=-1，则-1=-2x+3，得x=-2，故答案为：-2．（1）根据题意得到y=2x-1+3+ax=（2+a）x+2，由y的值与x的值无关，可知x的系数为0，即2+a=0，由此求得a的值；（2）结合（1）的a的值，可知当y=-1时，此时只有两个球相撞，分两种情况，从而可以求得x的值．本题考查有理数的混合运算、代数式求值，解答本题的关键是明确题意，求出a的值和相应的x的值．19.【答案】解：（1）原式=5-9÷（-3），=5+3，=8；（2）原式=，=-4-8+10，=-2．【解析】（1）先根据乘方的意义计算乘方运算，然后利用除法法则把除法运算化为乘法运算，根据负因式的个数判断得到结果的符号，最后利用加法法则即可得出结果；（2）根据乘法分配律进行计算即可．此题考查了有理数的混合运算，有理数的混合运算首先弄清运算顺序，先乘方，再乘除，最后算加减，有括号先计算括号里边的，且先小括号，再中括号，最后算大括号，同级运算从左到右依次计算，有时可以利用运算律来简化运算，熟练掌握各种运算法则是解本题的关键．20.【答案】解：（1）移项得：5x+2x=1-8，合并得：7x=-7，解得：x=-1；（2）去分母得：3（x+1）=2（2-3x），去括号得：3x+3=4-6x，移项合并得：9x=1，解得：x=．【解析】（1）方程移项合并，把x系数化为1，即可求出解；（2）方程去分母，去括号，移项合并，把x系数化为1，即可求出解．此题考查了解一元一次方程，熟练掌握运算法则是解本题的关键．21.【答案】解：3（2ab2-4a+b）-2（3ab2-2a）+b=6ab2-12a+3b-6ab2+4a+b=-8a+4b，∵2a-b=-2，∴原式=-8a+4b=-4（2a-b）=-4×（-2）=8．【解析】利用去括号法则和合并同类项的方法先对所求式子进行化简，然后根据2a-b 的值，即可求得所求式子的值，本题得以解决．本题考查整式的加减-化简求值，解答本题的关键是明确整式化简求值的方法．22.【答案】15【解析】解：（1）S=（1+2+3+…+9）÷3=45÷3=15．故答案为15；（2）由计算知：1+2+3+…+9=45．设中间数为x，依题意可列方程：4×15-3x=45，解得：x=5．故中间数x的值为5．（1）根据每一行三个数的和均为S，而这9个数的和恰好为1到9这9个正整数之和，由此可得S的值；（2）设中间数为x，利用包含中间数x的行、列、对角线上的数与9个数的关系列出方程，解方程即可．本题考查了一元一次方程的应用，理解洛书对应的九宫格的要求是解题的关键．23.【答案】两点之间，线段最短【解析】解：（1）如图，OD、OE为所作；（2）如图，点F为所作；（3）如图，点P为所作；（4）连接FC交OE于P，则根据两点之间，线段最短可判断此时PC+PF最小．答案为：两点之间，线段最短．（1）、（2）根据几何语言画出对应的几何图形；（3）连接CF交OE于P；（4）利用两点之间线段最短求解．本题考查了作图-复杂作图：复杂作图是在五种基本作图的基础上进行作图，一般是结合了几何图形的性质和基本作图方法．解决此类题目的关键是熟悉基本几何图形的性质，结合几何图形的基本性质把复杂作图拆解成基本作图，逐步操作．24.【答案】解：（1）方法一：∵AC=8，CB=2，∴AB=AC+CB=10，∵点M为线段AB的中点，∴，∴CM=BM-CB=5-2=3．或方法二：∴CM=AC-AM=8-5=3．（2）点M是线段CD的中点，理由如下：方法一：∵BD=AC=8，∴由（1）可知，DM=DB-MB=8-5=3．∴DM=MC=3，∴由图可知，点M是线段CD的中点．方法二：∵AC=BD，∴AC-DC=BD-DC，∴AD=CB．∵点M为线段AB的中点，∴AM=MB，∴AM-AD=MB-CB，∴DM=MC∴由图可知，点M是线段CD的中点．【解析】（1）方法一：根据线段的和差关系可求AB，再根据中点的定义可求BM，再根据CM=BM-CB或方法二：CM=AC-AM即可求解；（2）方法一：由（1）可知，DM=DB-MB，可得DM=MC，从而求解；方法二：根据等量关系可得AD=CB，根据中点的定义可得AM=MB，再根据等量关系可得DM=MC，从而求解．本题考查了两点间的距离，利用了线段的和差，线段中点的性质．25.【答案】x=2 1 3【解析】解：（1）当k=2，b=-4时，方程◇为：2x-4=0，x=2．故答案为：x=2；（2）答案不唯一，如：k=1，b=3．（只需满足b=3k即可）故答案为：1，3；（3）方法一：依题意：4k+b=0，∵k≠0，∴．解关于y的方程：，∴3y+2=-4．解得：y=-2．方法二：依题意：4k+b=0，∴b=-4k．解关于y的方程：k（3y+2）-（-4k）=0，3ky+6k=0，∵k≠0，∴3y+6=0．解得：y=-2．（1）代入后解方程即可；（2）只需满足b=3k即可；（3）介绍两种解法：方法一：将x=4代入方程◇：得，整体代入即可；方法二：将将x=4代入方程◇：得b=-4k，整体代入即可；本题考查了一元一次方程的解，熟练掌握解一元一次方程是关键．26.【答案】50°【解析】解：（1）∵∠AOC：∠BOD=4：5，∠BOD与∠AOC互余，∴∠BOD=90°×=50°；（2）①补全图形如下：∵∠BOD与∠AOC互余，∴∠BOD+∠AOC=90°，∴∠COD=90°，∵ON平分∠COD，∴∠CON=45°，∴∠AON=α+45°；②情形一：点D在∠BOC内．此时，∠AON=α+45°，∠COD=90°，依题意可得：α+45°+90°=180°，解得：α=45°．情形二：点D在∠BOC外．在0°＜α≤45°的条件下，补全图形如下：此时∠AON=45°，∠COD=90°+2α，依题意可得：45°+90°+2α=180°，解得：α=22.5°．综上，α的取值为45°或22.5°．故答案为：50°．（1）根据余角的定义即可求解；（2）①先根据余角、平角的定义求出∠BOC，再根据角平分线的定义求出∠COD，再根据角的和差关系即可求解；②分点D在∠BOC内，点D在∠BOC外两种情况即可求解．本题考查了余角和补角、角度的计算，正确理解角平分线的定义，理解角度之间的和差关系是关键．27.【答案】2 1，2，3 是【解析】解：（1）对于数阵A，2*3的值为2；若2*3=2*x，则x的值为1，2，3；（2）①由数阵图可知，数阵A是“有趣的”．②∵1*2=2，∴2*1=（1*2）*1，∵（a*b）*c=a*c，∴（1*2）*1=1*1，∵a*a=a，∴1*1=1，∴2*1=1．（3）不存在理由如下：方法一：若存在满足交换律的“有趣的”数阵，依题意，对任意的a，b，c有：a*c=（a*b）*c=（b*a）*c=b*c，这说明数阵每一列的数均相同．∵1*1=1，2*2=2，3*3=3，∴此数阵第一列数均为1，第二列数均为2，第三列数均为3，∴1*2=2，2*1=1，与交换律相矛盾．因此，不存在满足交换律的“有趣的”数阵．方法二：由条件二可知，a*b只能取1，2或3，由此可以考虑a*b取值的不同情形．例如考虑1*2：情形一：1*2=1．若满足交换律，则2*1=1，再次计算1*2可知：1*2=（2*1）*2=2*2=2，矛盾；情形二：1*2=2由（2）可知，2*1=1，1*2≠2*1，不满足交换律，矛盾；情形三：1*2=3若满足交换律，即2*1=3，再次计算2*2可知：2*2=（2*1）*2=3*2=（1*2）*2=1*2=3，与2*2=2矛盾．综上，不存在满足交换律的“有趣的”数阵．故答案为：2；1，2，3；是．（1）根据定义a*b为数阵中第a行第b列的数即可求解；（2）①根据“有趣的”定义即可求解；②根据a*a=a；（a*b）*c=a*c，将2*1变形得到2*1=（1*2）*1即可求解；③若存在满足交换律的“有趣的”数阵，依题意，对任意的a，b，c有：a*c=（a*b）*c=（b*a）*c=b*c，这说明数阵每一列的数均相同．进一步得到1*2=2，2*1=1，与交换律相矛盾．因此，不存在满足交换律的“有趣的”数阵．考查了规律型：数字的变化类，探究题是近几年中考命题的亮点，尤其是与数列有关的命题更是层出不穷，形式多样，它要求在已有知识的基础上去探究，观察思考发现规律．。

You may think the firsthamburgers, of course, comes from the United States or Germany. But the fact isthat it comes from China.If you're thinking it is impossible right now, you're not alone. Rou jia mois called Chinese hamburger. It is said to be the world's first hamburger. Roujia mo appeared earlier than American ones, from about 221 BC to 207 BC. Chinesehamburgers are "meat burgers" or "meat sandwiches." They are very real —with a lot of meat inside without any vegetables, which is quite different from the American-style burgers.It was a street food in Shanxi Province of China in the past, and is now eaten all over the country. It's usually prepared and eaten on the street. While the bun is traditionally baked in a clay oven, today it's often fried in a pan. The bun, or mo in Chinese, is made up of a simple mixture （混合物） of wheal flour and water. And this makes a chewy （有嚼劲的） and fine bun, or mo, for the delicious filling. The meat filling might be pork, beef, lamb or chicken that has been （炖） for hours.Rou jia mo usually costs about 6 yuan each in most parts of China. You can find it everywhere. It is the best snack between meals when visiting some places. If you try it once, you will never forget this "mouth-watering" food.(1)What is rou jia mo called?(2)When did rou jia mo appear?(3)Do people eat rou jia mo all over China now?(4)How much is rou jia mo in most parts of China?(5)What do you think of rou jia mo according to the passage?书面表达17根据下面各题所给的中文及英文提示，完成下面的句子。

skills．Time management is hard to practice well．But once done，you will manage time much better．With minor tweaks and little efforts，you can do all you need to do in an effective（有效率的）way．The key to good time management is to understand the difference between the urgent and the important．"Urgent"tasks need your immediate（立即的）attention，but whether you give that immediate attention may or may not matter（要紧）．"Important"tasks matter，because not doing them may have serious or even bad results．For example，answering the phone is urgent．If you don't do it，you may miss something important．However，it may be a stranger who just wants to sell you a phone you don't need at all．That's not important．Going to the dentist is important．If you don't，you may get gum disease．But it's not urgent．If you leave it too long，however，it may become urgent，because you may get a toothache．Helping to pick up your brother or sister from school is both urgent and important．If you are not there at the right time，they will keep waiting and worry too much．Seeing Wechat moments（朋友圈）is neither urgent nor important．So why do you put it first？Knowing the difference between the urgent and the important is the key to

began in the15th century．Ballet dancers may be men and women﹣ballet is not just for girls!They are strong，pretty，and flexible（柔韧的）．Many movements in ballet are unusual for the human body．Dancers turn their legs out，instead of having their knees and feet straight forward．They also point their feet and may even dance on the tips of their toes．Dancers must go through a lot of training．Many take classes almost daily if they'd like to be professional（职业的）ballet dancers．They need to practice often to keep up theirstrength．That also means that dancers need to take very good care of their bodies，so their bodies can keep up with the dancing!Dancers need to be well rested and eat healthy meals．They also should drink plenty of water and listen to their bodies by resting if that's what their bodies need．In ballet class，most teachers ask dancers to warm up their bodies at first．After that，dancers come to the center to practice other movements．They should start slowly when learning new steps，so their bodies have time to get used to the steps and not get injured．In fact，it is not easy to become good ballet dancers．Not only do dancers need to control their bodies well，but they need to have a good understanding of music．Ballet looks soft，but it is really an athletic activity．If you love to move your body and use it to tell stories，ballet might be a great activity for you to try!（1）When did the first ballet begin？In the15th century（2）Is ballet just for girls？No，it isn't（3）Why do professional ballet dancers need to practice often？Because they need to keep up their

三、现代文阅读（共20分）（一）阅读《我愿意去读懂你》，完成17-21题。
（共15分）我愿意去读懂你王小毛我真后悔给爸买智能手机，更后悔教会他刷朋友圈。
周一我在公司被忙碌的工作牵得团团转，郁闷地在朋友圈发了条动态：“一个上午累成狗。
”几分钟后，手机提示音响个不停，全是爸发来的超长语音。
我以为家里出了什么大事，赶紧放下工作躲进厕所收听。
哦，原来是一堂生动的思想教育课，最后还说：“不要把自己和狗相提并论，你是狗，你爸是什么？”我抱着手机，真是哭笑不得，不知和爸从何说起。
一个周末，我约了闺蜜去逛街，回来时发现好端端的家被我表妹一条名叫“肉肉”的哈士奇狗给“强拆”了，可是肇事者一脸不屑地蹲在门口根本没表现出一点儿愧疚之意。
卫生纸被撕碎了，我忍；沙发被啃了，也可不计较；但当我看到摔碎的粉饼和折断的口红时，一股怒火攻上心头，立刻拍照片配上狠话发到朋友圈：“这种狗怎么炖好吃？”几分钟后，我爸的斥责电话就打了进来：“你是不是疯了，为了这么点儿事儿就要杀肉肉！”我实在无语。
为避免爸产生不必要的误解，从此后我再发朋友圈，都会选择性地屏( bì)他，仅向他展示自己“积极向上”的一面。
因此，爸的唠叨明显少了。
【有一天，天气甚好，我穿着新买的春装去公园玩儿。
因为知道爸喜欢我参加户外活动，便拍了几张美图展示健康生活理念。
爸好像一直擎着手机窥探我，整日无事可做，只等待另一头伺机而动——照片刚发好，就是一个秒赞。
可接着我又收到三篇“深度好文”，大概是“小心病从脚入…‘女人最怕脚受凉…‘足部穴位详图”这类的标题。
唉，真是防不胜防！为了扮潮，我特意露出一截脚踝。
谁承想大好春色他不看，偏偏把注意力放在我的脚上。
我赶紧解释，气温回升一点儿都不冷，街上的小姑娘都这样打扮。
爸大概觉得用语音说费事，直接打电话过来。
最后的结果是我只好妥协，下午回家换了长裤、长袜，并拍照片儿发给他看。
此后，我每天都能收到爸推送的“养生文”，感觉自己有望活到下个世纪。
】十一假期到来的前三天，爸一改风格，每天准时分享两篇“感恩父母”系列文章，接着还发来这样的语音：“女儿呀，你要是忙就不要回来了！爸特别好……咳……咳……”听听，我怎么能不回去？那日下了出租车，只见爸满面红光地在小区门口等我，一边还在和几位邻居侃大山。
我主动和几位叔叔打招呼，爸对我的举止、衣着特别满意，在回家的路上不停地示好：“女儿呀，老爸给你做了一桌好吃的！”爸的厨艺确实很好，我空着肚子赶火车，早已饿得饥肠辘辘，一见蛋黄煸鸡翅、蒜蓉开背虾、红烧排骨，我扑上去抄起筷子准备开吃，却被爸叫停：“等下！我先拍个照！”为了取个全景，爸踩着一个小凳子，其间三次下来调整摆盘，好不容易拍完饭桌，为了凑“九宫格”，他还要拍我送他的礼物，以及我吃得满嘴流油的囧样子。
他没完没了地折腾，根本顾不上吃饭，我风卷残云，吃饱喝足后，见他扔弓着身子不停地删删改改。
我一直觉得，爸身上有一种与年龄不符的幼稚。
印象中，爸是我周围第一个接触QQ的家长。
我读中学时，有一天放假，我在电脑前和网友聊得甚欢，爸借着送水果的机会，在我身后磨磨蹭蹭半天，最后用讨好的口气问：“宝贝女儿，你能不能帮爸爸申请一个QQ号？”当爸可以在我的个人空间自由出入的时候，我已经悄悄玩起了微博，没有爸这个“好友”跟踪，我终于可以肆无忌惮地宣泄情绪。
我原本不想让他知道，可一次亲戚聚会，表弟在饭桌上大咧咧地问我：“姐，你关注一下我的微博，@我一下呗！”我感觉情况不妙。
果然爸迅速从推杯换盏的氛围中抽离，一脸疑惑地问：“啥是微博？怎么关注？”于是，我又成了爸的“特别关注”。
这些年，爸一路跟着我，从QQ到微博，再到微信，一直艰难地适应着这个日新月异的网络时代。
但他用尽全力也只做到了形式上的趋从——他其实并不懂我，更猜不透我在想什么。
，爸发完朋友圈，才安心地坐到饭桌前。
饭菜已经凉透，我提出给他热一下，他却说：“不用了，你快去给爸点赞。
”我只好听他的话，点进他的朋友圈，手动点赞。
是的，我把爸设为不看他的朋友圈，因为受不了他动辄用养生好文刷屏。
