【推荐指数】★★★★22．（2010重庆，22，10分）已知：如图，在平面直角坐标系xOy 中，直线AB 与x 轴交于点A （－2，0），与反比例函数在第一象限内的图象的交于点B （2，n ），连结BO ，若S △AOB ＝4．（1）求该反比例函数的解析式和直线AB 的解析式；（2）若直线AB 与y 轴的交点为C ，求△OCB 的面积．【分析】运用待定系数法确定函数解析式，三角形面积的计算方法可以表先求出点B 的坐标，然后分别代入即可求出直线和反比例函数的解析式．【答案】解：（1）因为直线AB 与x 轴交于点A （－2，0），所以OA ＝︱－2︱＝2，且S △AOB ＝12B AO y 所以：12B AO y ＝4，即122B y ⨯＝4，所以B y ＝4，又因为点B 在第一象限，所以B y ＝4，即点B 的纵坐标为4，所以点B 的坐标为（2，4），设直线的解析式为y kx b =+，反比例函数为ay x=，将A （－2，0）、B （2，4）y kx b =+得：0242x b k b =-+⎧⎨=+⎩解之得：21b k =⎧⎨=⎩，所以设直线的解析式为2y x =+B （2，4）代入a y x =得：8a =，所以反比例函数解析式为：8y x=．（2）将x ＝0代入2y x =+得y ＝2，即点C 的坐标为（0，2）因为OBC OBA AOC S S S ∆∆∆=-OCB ＝4－12AO OC ∙＝4－2＝2．所以△OCB 的面积为2．【涉及知识点】待定系数法确定函数解析式．【点评】本题通过待定系数法确定函数解析式，注意对三角形的面积计算的应用，适当应用图形的分割法，将问题简化．待定系数法确定函数解析式是中考的一个热点问题． 【推荐指数】★★★★

现要从发了3条箴和4条箴言的同学中分别选出一位参加该校团委组织的“箴言”活动总结会，请你用列表法或树状图的方法求出所选两位同学恰好是一位男同学和一位女同学的概率．【分析】根据两幅不完整的统计图寻找出有用的信息，再分别计算出其他的数据，根据数据再将条形图补充完整．然后根据概率的计算方法计算出相应的概率． 【答案】（1）由扇形图可以看到发箴言三条的有3名学生且占25％，所以，总人数为：3÷25％＝12(人)，所以发4条的同学人数为：12－2－2－3－1＝4（人），本月学生发的箴言共2×1＋2×2＋3×3＋4×4＋1×5＝36．则平均所发的条数是：36÷12＝3(条) （2）可以用如下图的树形图表示出来，由树形图可以看到共有12种可能，并且每种情况出现的机会均等，恰好为一男一女的共有7种可能，所以恰好是一位男同学和一位女同学的概率为：712P． 【涉及知识点】统计图的表示，概率的计算．【点评】本题是数据描述和概率计算的基本题型，是对学生基本运算能力的考查，树形图或列表的方法是解决概率经常运用的方法．数据的描述和概率是中考的一个热点问题，尤其是概率是中考中经常与其他的知识相结合． 【推荐指数】★★★★24．（2010重庆，24，10分） 已知：如图，在直角梯形ABCD 中，AD ∥BC ，∠ABC ＝90°．点E 是DC 的中点，过点E

＝120°就好了，而∠MFC ＝120°，所以需要证明： ⊿AM D ≌⊿F MC ，然后分别求出各角，即可得出结论． 【答案】（1）连接MD ，∵点E 是DC 的中点，M E ⊥DC∴MD ＝MC （线段垂直平分线的性质）在⊿AM D 和⊿F MC 中，CF ＝AD ，MF ＝MA ，MD ＝MC ∴⊿AM D ≌⊿F MC （sss ） ∴∠MAD ＝∠MFC ＝120° 又∵AD ∥BC ，∠ABC ＝90°∴∠BAD ＝90°∴∠MAB ＝120°－90°＝30° ∴AM ＝2MB (2) ∵AD ∥BC∴∠ADM ＝∠DMB ， 又∵⊿AM D ≌⊿F MC ∴∠ADM ＝∠MCF ∴∠DMB ＝∠MCF又∵点E 是DC 的中点，M E ⊥DC∠DME ＝∠PMB ＝ 12∠MCF在R t ⊿PMB 中 ∵∠PBM ＝90°∴∠MPB ＝90°－∠PMB即：∠MPB ＝90°－

＋2．试问4月份与5月份分别在哪一周销售此种蔬菜一千克的利润最大？且最大利润分别是多少？ （3）若5月份的第2周共销售100吨此种蔬菜．从5月份的第3周起，由于受暴雨的影响，此种蔬菜的可供销量将在第2周销量的基础上每周减少a %，政府为稳定蔬菜价格，从外地调运2吨此种蔬菜，刚好满足本地市民的需要，且使此种蔬菜的销售价格比第2周仅上涨0．8 a %．若在这一举措下，此种蔬菜在第3周的总销售额与第2周刚好持平，请你参考以下数据，通过计算估算出a 的整数值． （参考数据：372＝1369，382＝1444，392＝1521，402＝1600，412＝1681）【分析】本题考查待定系数法确定函数解析式的和应用函数解决实际问题，在四月份可以看出4月份y 与x 的函数关系式应符合一次函数的关系，将五月的两对数值代入即可求出二次函数的解析式，第二问根据利润等于售价减去进价列出函数关系式比较得出函数关系式比较即可，第三问根据；总销售额＝售价×出售的量，并且第三周的总销售额与第2周刚好持平得到等量关系． 【答案】（1）通过观察可见四月份周数y 与x 的符合一次函数关系式：y ＝0．2x ＋1．8;将（1，2．8）(2，2．4)代入y ＝－ 1 20 x 2＋bx ＋c ．可得：12.82012.425b c b c ⎧=-++⎪⎪⎨⎪=-++⎪⎩解之：143.1b c ⎧=-⎪⎨⎪=⎩ 即y ＝120-x 2 14-x ＋3．1（2）4月份此种蔬菜利润可表示为：W 1＝y －m ＝（0．2x ＋1．8）－（ 14 x ＋1．2），即： W 1＝－0．05x ＋0．65月份此种蔬菜利润可表示为： W 2＝y －m ＝（120-x 2 14-x

整数约为8．【涉及知识点】函数解析式的应用，一元二次方程的解法．【点评】待定系数法确定函数解析式是中考的热点问题，尤其是第一问中对函数的认识通过各点的特点来判断变量之间的函数关系式；在本题中的第三问中数据较多，需要学生能够在众多的数据中理清等量关系，代入计算，还要熟练掌握一元二次方程的求根公式法的应用．【推荐指数】★★★★★★26．（2010重庆，26，12分）已知：如图（1），在平面直角坐标xOy 中，边长为2的等边△OAB 的顶点B在第一象限，顶点A 在x 轴的正半轴上．另一等腰△OCA 的顶点C 在第四象限，OC ＝AC ，∠C ＝120°．现有两动点P 、Q 分别从A 、O 两点同时出发，点Q 以每秒1个单位的速度沿OC 向点C 运动，点P 以每秒3个单位的速度沿A →O →B 运动，当其中一个点到达终点时，另一个点也随即停止．（1）求在运动过程中形成的△OPQ 的面积S 与运动的时间t 之间的函数关系，并写出自变量t 的取值范围；（2）在等边△OAB 的边上（点A 除外）存在点D ，使得△OCD 为等腰三角形，请直接写出所有符合条件的点D 的坐标；（3）如图（2），现有∠MCN ＝60°，其两边分别与OB 、AB 交于点M 、N ，连接MN ．将∠MCN 绕着C点旋转（0°＜旋转角＜60°），使得M 、N 始终在边OB 和边AB 上．试判断在这一过程中，△BMN 的周长是否发生变化？若没有变化，请求出其周长；若发生变化，请说明理由．【分析】在本题中是双动点问题，要计算三角形的面积需要分别表示出三角形的底和高，然后代入面积公式，注意分段函数的不同表达方式，在第二问中，直接写答案，需要学生考虑全面不可遗漏，第三问中要注意旋转的应用，问题的关键是理解MN ＝OM ＋AN ．【答案】解：（1）如图，过点Q 作QE 垂直x 轴，垂足为E ，过点C 作CF 垂直x 轴，垂足为F ， 在Rt ⊿OQE 中，∵OQ ＝t ，∠EOQ ＝30°，sin 30QE OQ ︒=，∴sin 302t OE QO =⨯︒= 第一种情况，点P 运动到O 点前：在⊿OQP 中∵OP ＝2－3t ，∴11(3)(3)2224OPQ t t t S OP QE t ∆-=⨯=⨯-=（0＜t ＜23） 第二种情况，点Q 运动到C 点前：在⊿OQP 中，∵∠AOQ ＝30°， ∠BOA ＝60°，∴∠POQ ＝90°∴11(32)(32)222OPQ t t S OP OQ t t ∆-=⨯=⨯-=（23＜t ＜3）(2)如图可以看到有三个点：1D （23，0），2D （3，1），3D （43，23） (3) 如图将CNA ∆绕着点C 旋转120°（A '与O 重合）使得CNA ∆落到CN A ''∆处．则CNA ∆≌CN A ''∆（旋转的性质）∴CN '＝CN ， A N ''＝AN ，∠NCA ＝∠N CA ''，∴∠NCM ＝∠N CM '在MCN ∆和CN M '∆中∠NCM ＝∠N CM '，CN '＝CN ，CM ＝CM ，∴MCN ∆≌CN M '∆，∴MN ＝N M '，即MN ＝A N ''＋A M '，∴MN ＝AN ＋OM ，则△BMN 的周长为：BM ＋BN ＋MN ＝BM ＋BN ＋AN ＋OM ＝OB ＋AB ＝4所以则△BMN 的周长为定值，这个定值是4．【涉及知识点】直角三角形的性质，等腰三角形的性质，三角形全等的判定和性质，旋转的应用、相似三角形．【点评】本题第一问是典型的双动点的问题，是分段函数，需要学生能准确把握两种情况，并且要注意第二种情况是直角三角形；第二问中共有三个点，学生很容易找到前两个，第三个不易找到，并且计算坐标用到相似三角形的知识，学生也很难完整的把本题做出解答；本题具有较强的综合性，涉及到了多个知识点，需要学生具有扎实的基础知识和综合能力．【推荐指数】★★★★★。

It is also known as kiteboarding, and in some European countries as flysurfing. Kitesurfing works through wind power(动力) by using a large kite to pull arider on the water at high speed.At first, kitesurfing was a difficult and dangerous sport. Now it is becoming easier and safer because of the safer kite design. For an able and strong person, kitesurfing can be a very fun, extremely exciting sport, just like skating on the water with a feeling of flying. It has become more and more popular.Compared with other water sports, kitesurfing is easier to learn. A beginner can understand how to operate the kite with 5—10 hours of training. And anybody aged from 13 to 65 can learn. It is not expensive to get the equipment for kitesurfing, which costs $1,000 to $2,500. Training lessons range from $200 to $500 for two or three hours. With the development of its equipment progress, kitesurfing is becoming even safer. After some training, you can enjoy its excitement and challenging feeling.With the rising popularity of kitesurfing, most major seaside cities have kitesurfing clubs. In China, Xiamen is the only place that has the kitesurfing club, which provides professional kitesurfing training and equipments.【小题1】Kitesurfing has a history of about years.A．30B．50C．100D．130【小题2】 is mentioned in the passage as the power of kitesurfing.

Peter Corbett helped Mark Wellman out of his wheelchair and onto the ground. They stood before El Captain, a huge rock almost 1.2 kilometers high. Mark had long dreamed to climb El Captain when he was a child. At the age of twenty one, he had fallen while climbing mountain, losing his legs. But he never losthis love for life.Mark knew he couldn't finish the climb alone, but his friend Peter would be there to lend a helping hand. They thought it would take seven days to reach the top. Now Peter climbed about 30 meters up and hit a piton(岩钉) into the rock. Fastening(拴紧) one end of a 50meter rope(绳子) to the piton, he let the other end of the rope fall down.Mark caught the rope and fastened it to his belt. He next reached above his head and fastened a T-bar(丁字铁) to the rope. Mark took a deep breath, pushed the T bar up almost as far as his arms could reach, and began the first pull up. High above, Peter let out a cheer, “You're on your way.”For the first four days the two men progressed upward(向上) without accident. But on the fifth day, a very strong wind began to blow, making it hard for Mark to hold on to his rope. But Mark kept on pushing up the T-bar and pulling himself up.It took them one day more than they had expected. But as the two heads appeared the group of people waiting on the top went wild with joy.Mark Wellman showed that if you set your heart and mind on something, no wall is too high, no dream impossible.【小题1】 With the help of his friend, Mark could climb up El Captain about meters in height each day.A．300B．150C．50D．30【小题2】While climbing, Mark .A．carried the T-bar on his back and stepped upwardB．pushed up the T-bar and pulled himself upC．sat in his wheelchair and pushed himself upD．held on to the rope drawn up by his friend【小题3】Which is the correct order of the steps before Mark's climbing?a. push up the T-barb. tie the rope to his beltc. hit the piton into the rockd. fasten the T-bar to the ropee. tie the rope to the pitonA．c e b d aB．e c a b dC．e b d c aD．b d e c a【小题4】Which of the following is true of Mark Wellman?A．He realized his dream without anyone helping him.B．He was badly injured when he climbed El Captain.C．He dreamed to climb up El Captain for a long time.D．He climbed up the rock by using a tool for the disabled.【小题5】What can we learn from the passage?A．A friend in need is a friend indeed.B．Dreams will come true in the end.C．Each step is important to success.D．Nothing can stop a strong will.20.【小题1】Paul tried to open the door but it didn't work.（改为同义句）Paul tried to open the door but ▲ .【小题2】I want one kilo of fish.（对划线部分提问）▲▲▲ of fish do you want?【小题3】 The news report is very exciting.（改为感叹句）▲▲ exciting news report it is l【小题4】 His mother came home.

中考英语专题3：句型转换
专题三、句型转换【知识盘点】句型转换这一题型是先给出一个句子，然后再给出一个包含几个空白处的句子，要求根据括号内的具体要求在第二句的空白处填入适当的词来完成。
它有完全的句式转换和句子中某一部分或几部分的转换。
该题型主要考查同学们的语言基础知识及句子结构的构成、变化、运用等。
其特点是规律性强、灵活性小，旨在考查考生用不同的句型结构来表达相同、相近或相反的语意的能力，训练灵活运用语言的技巧。
【命题规律】从题型上看，句型转换可分为两大类：一是按要求改写句子。
即按照指定要求将原句改写成其他形式的句子，如肯定句改为否定句，陈述句改为一般疑问句、特殊疑问句、反意疑问句、感叹句，对划线部分提问等。
另一类是同义句、近义句的转换，即要求用不同的句型，不同的语言手段表达相同的思想。
【命题趋势】从近年来的考题趋势来看，句型转换从单纯测试语法知识向改变句子结构填空，填词后使句意不变或与要求相符的方向发展。
其中许多属于常用句型。
【解题技巧】一、肯定句改为否定句1. 改变谓语结构在系动词be, become, feel, smell等，助动词be, have, do 等以及情态动词can, may, should等后加not。
如果句子的谓语中不是以上这些词，而是行为动词，则相应地将动词的原形，第三人称单数或过去式变为否定形式。
如：He has seen the film before.→He hasn’t seen the film before.He will write the book in two months.→He won’t write the book in two months.He does his homework in the evening.→He doesn’t do his homework in the evening.2. 用含否定意义的词（如never, nothing, nobody, none, neither, little, few等）。
