＝∠B+∠BAD，列式可得结论．解：（1）①∵∠DAE＝30°，∴∠ADE+∠AED＝150°，∴∠ADE＝∠AED＝75°，∵∠BAC＝42°，∴α＝42°﹣30°＝12°，∴∠ACB＝∠B＝＝69°，∵∠ADC＝∠B+α，∴75°+β＝69°+12°，β＝6°；故答案为：12°，6°；②∵∠DAE＝36°，∴∠ADE+∠AED＝144°，∴∠ADE＝∠AED＝72°，∵∠BAC＝54°，∴α＝54°﹣36°＝18°，∴∠ACB＝∠B＝＝63°，∵∠ADC＝∠B+α，∴72°+β＝63°+18°，β＝9°；故答案为：18°，9°；③α＝2β，理由是：如图（1），设∠BAC＝x°，∠DAE＝y°，则α＝x°﹣y°，∵∠ACB＝∠ABC，∴∠ACB＝，∵∠ADE＝∠AED，∴∠AED＝，∴β+∠ADE＝α+∠ABC，β+＝α+，∴α＝2β；（2）α＝2β﹣180°，理由是：如图（2），设∠E＝x°，则∠DAC＝2x°，∴∠BAC＝∠BAD+∠DAC＝α+2x°，∴∠B＝∠ACB＝，∵∠ADC＝∠B+∠BAD，∴β﹣x°＝+α，∴α＝2β﹣180°．【点评】本题是三角形的综合题，难度适中，考查了等腰三角形的性质、三角形内角和定理、三角形外角的性质，熟练掌握等腰三角形的性质是关键，知道顶角的度数可以表示两个底角的度数，同时运用了类比的方法解决三个问题．七、解答题（本题满分12分）22．为了推动“龙江经济带”建设，我省某蔬菜企业决定通过加大种植面积、增加种植种类，促进经济发展．2017年春，预计种植西红柿、马铃薯、青椒共100公顷（三种蔬菜的种植面积均为整数），青椒的种植面积是西红柿种植面积的2倍，经预算，种植西红柿的利润可达1万元/公顷，青椒1.5万元/公顷，马铃薯2万元/公顷，设种植西红柿x公顷，总利润为y万元．（1）求总利润y（万元）与种植西红柿的面积x（公顷）之间的关系式．（2）若预计总利润不低于180万元，西红柿的种植面积不低于8公顷，有多少种种植方案？（3）在（2）的前提下，该企业决定投资不超过获得最大利润的在冬季同时建造A、B 两种类型的温室大棚，开辟新的经济增长点，经测算，投资A种类型的大棚5万元/个，B种类型的大棚8万元/个，请直接写出有哪几种建造方案？【分析】（1）根据总利润＝三种蔬菜的利润之和，计算即可；（2）由题意，列出不等式组即可解决问题；（3）由题意，列出二元一次不等式，求出整数解即可；解：（1）由题意y＝x+1.5×2x+2（100﹣3x）＝﹣2x+200．（2）由题意﹣2x+200≥180，解得x≤10，∵x≥8，∴8≤x≤10．∵x为整数，∴x＝8，9，10．∴有3种种植方案，方案一：种植西红柿8公顷、马铃薯76公顷、青椒16公顷．方案二：种植西红柿9公顷、马铃薯73公顷、青椒18公顷．方案三：种植西红柿10公顷、马铃薯70公顷、青椒20公顷．（3）∵y＝﹣2x+200，﹣2＜0，∴x＝8时，利润最大，最大利润为184万元．设投资A种类型的大棚a个，B种类型的大棚b个，由题意5a+8b≤×184，∴5a+8b≤23，∴a＝1，b＝1或2，a＝2，b＝1，a＝3，b＝1，∴可以投资A种类型的大棚1个，B种类型的大棚1个，或投资A种类型的大棚1个，B种类型的大棚2个，或投资A种类型的大棚2个，B种类型的大棚1个，或投资A种类型的大棚3个，B种类型的大棚1个．【点评】本题考查一次函数的应用．一次一次不等式组等知识，解题的关键是学会利用一次函数解决最值问题，学会利用不等式求整数解解决问题，属于中考常考题型．八、解答题（本题满分14分）23．甲、乙两车从A地驶向B地，并以各自的速度匀速行驶，甲车比乙车早行驶2h，并且甲车途中休息了0.5h，如图是甲乙两车行驶的距离y（km）与时间x（h）的函数图象．（1）求出图中m，a的值；（2）求出甲车行驶路程y（km）与时间x（h）的函数解析式，并写出相应的x的取值范围；（3）当乙车行驶多长时间时，两车恰好相距50km．【分析】（1）根据“路程÷时间＝速度”由函数图象就可以求出甲的速度，求出a的值和m的值；（2）由分段函数当0≤x≤1，1＜x≤1.5，1.5＜x≤7由待定系数法就可以求出结论；（3）先求出乙车行驶的路程y与时间x之间的解析式，由解析式之间的关系建立方程求出其解即可．解：（1）由题意，得m＝1.5﹣0.5＝1．120÷（3.5﹣0.5）＝40，∴a＝40．答：a＝40，m＝1；（2）当0≤x≤1时设y与x之间的函数关系式为y＝k1x，由题意，得40＝k1，∴y＝40x当1＜x≤1.5时，y＝40；当1.5＜x≤7设y与x之间的函数关系式为y＝k2x+b，由题意，得，解得：，∴y＝40x﹣20．y＝；（3）设乙车行驶的路程y与时间x之间的解析式为y＝k3x+b3，由题意，得，解得：．∴y＝80x﹣160．当40x﹣20﹣50＝80x﹣160时，解得：x＝．当40x﹣20+50＝80x﹣160时，解得：x＝．＝，．答：乙车行驶小时或小时，两车恰好相距50km．。

He began to make friends with Bruce Lee.B. He began to take an interest in China.C. He began to learn Beijing Opera in Beijing.D. He began to act the part of the Monkey King.44.What does the underlined word "obstacle" in Paragraph 3 probably mean？______A. chanceB. problemC. topicD. dream45.What can be inferred from the passage about Ghaffar？______A. He is successful in performing Beijing Opera.B. He has written some books about Beijing Opera.C. He got a prize for translating Journey to the West.D. He doesn't need any more members in his team.EIs advertisement really necessary？Billions of dollars are spent on it every year,so it must be important.After all,it's a busy world.You have to advertise to get people's attention to sell products!Not every company thinks that way,however.The NO-AD company doesn't advertise in traditional ways.It sells its products by word of mouth.In this way,they,can save money and keep costs down,which makes their products cheaper for customers."Word-of-mouth advertising" happens when one person tells another about a goodexperience with a product or service.That next person then tells another friend,familymember,or colleague （同事）.And so a chain of information is created.Usually,advertisers talk about how good their product is.Although they say thingslike,"Studies show that our product is the best." or "Everyone loves this product."it can sound unconvincing.It's much more believable to hear about a product from a familymember or a friend who has used it.Our loved ones' opinions are very important to us,so we often listen to their advice about a product.Word-of-mouth advertising has other advantages,too.It's cost-effective（after all,it's free）and a company doesn't have to create a complex business plan to do it.Here is some advice for small businesses about word-of-mouth advertising.*Be prepared to talk about your company at any time.You never know who you willmeet.Always carry business cards.*Only say good things about your company.Don't say bad things about your company.*Help other companies by recommending people to them.The more you help others,the more good luck will come back to you,and that's good business.46.Why do some companies spend lots of money on advertisements？______A. To attract people to their products.B. To make the environment beautiful.C. To tell people the names of their companies.D. To make their products very useful.47.If someone says,"I always buy it."，the speaker probably means to ______ .A. sell the product to her familyB. tell her customer about the serviceC. buy the product for her colleagueD. recommend the product to her friend48.What does the underlined word "unconvincing" in Paragraph 4 probably mean？______A. uncomfortableB. unimportantC. unbelievableD. unusual五、任务型阅读-简答（本大题共1小题，共6.0分）49.I hit a stranger as he walked by me,"Oh,excuse me."I said.He replied with a smile andsaid,"Please excuse me too.I wasn't watching out for you."We said sorry to each other and went our own ways.Later that day,when I was cooking,my daughter was standing too close to me.When Iturned to reach for some milk,I nearly knocked her over. "Move out of the way!"Ishouted.She walked away sadly.While I was in bed that evening,my husband said to me,"While dealing with astranger,you were polite,but with a daughter you love,you were unkind.Your daughter brought you some flowers that she picked herself this afternoon.You'll find them in the kitchen by the door."I quietly went to my daughter's bed."Dear,I'm so sorry,"I said,"Are these the flowers youpicked for me？"She said,"I found them by the tree.I picked them because they're pretty like you.I knew you'd like them.""I replied,"I'm really sorry for the way I acted today.I shouldn't have shouted at you.""It's okay.I love you anyway,"she said as she kissed me.It's important and necessary for us to be kind to our loved ones.Everyone can live in a happy family if they do like this.(1) What was the writer doing when her daughter stood close to her that day？（不超过5个词）______(2) What did the writer's daughter bring her that day？（不超过5个词）______(3) What can we learn from this passage？（不超过15个词）______六、单词拼写/单词释义（本大题共4小题，共4.0分）50.People shouldn't be allowed to drive a car without a driver's l______（证件）.51.Five visitors will a ______（参加）tomorrow's meeting,including two Americans.52.The spread of the virus will be p ______（阻止）well by washing hands often.53.Miss Chen p______（更喜欢）to have offline classes rather than online classes.七、单词拼写-单句（本大题共1小题，共1.0分）54.The six-year-old American girl has learned hundreds of Chinese p______（诗）．八、书面表达（本大题共1小题，共20.0分）55.假如你是Helen,你知道你的父母很爱你，但是他们给你立的规矩太多，过于强调你的学习成绩，你感觉他们不理解你，你感到很沮丧。
