=，∴AC=2AF=．【解析】（1）由平行四边形的判定定理：两组对边分别平行得到结论；（2）由角平分线、等量代换得到角相等，由等角对等边得到BD=AB=5，根据勾股定理列方程求解．本题考查了平行四边形的判定和性质，角平分线的性质，勾股定理的应用，解题的关键是利用勾股定理列方程．25.【答案】2号线；52＜x≤72；22.2；30【解析】解：（1）每周乘地铁1-2次的所占的百分比是：1-29.7%-12.1%-9.0%-12.2%=37%；；（2）调价后客流量下降百分比最高的线路是2号线，调价后里程x （千米）在52＜x≤72范围内的客流量下降最明显．增长率最高的线路是15号线，预计2016年1月这条线路的日均客流量将达到：17.3×（1+28.15%）≈22.2（万人）； 故答案是：2号线，52＜x≤72，22.2；（3）调价后小王每周（按5天计算）乘坐地铁的费用比调价前多支出：5×5×2×2×（5-2）=30（元）． 故答案是：30．（1）利用1减去其它组的百分比，即可求得每周乘地铁1-2次的所占的百分比； （2）根据调整后部分路线的客流量及变化率即可直接求得； （3）根据15.9公里确定调整后的票价，即可求解．本题考查的是条形统计图和扇形统计图的综合运用，读懂统计图，从不同的统计图中得到必要的信息是解决问题的关键．条形统计图能清楚地表示出每个项目的数据；扇形统计图直接反映部分占总体的百分比大小． 26.【答案】解：（1）如图，（2）∠BAD =∠BED ．理由如下：连结BC 、CD ，如图，∴AB 为⊙O 的直径，的直径， ∴∠ACB =90°， ∴BC ⊥AC ，∵直线l 与MA 所在直线关于直线MD 对称， ∴MD 平分∠EMC ，∴BC =BE ，∴点C 与点E 关于直线MD 对称， ∴△BCD ≌△BED ， ∴∠BCD =∠BED ， ∵∠BCD =∠BAD ， ∴∠BAD =∠BED ． 【解析】（1）连结两条线段即可；（2）连结BC 、CD ，如图，根据圆周角定理得到∠ACB=90°，则BC ⊥AC ，再根据轴对称的性质得到MD 平分∠EMC ，于是根据角平分线的性质得BC=BE ，所以可判断点C 与点E 关于直线MD 对称，得到△BCD ≌△BED ，则∠BCD=∠BED ，再由圆周角定理得∠BCD=∠BAD ，于是得到∠BAD=∠BED ． 本题考查了圆周角定理：在同圆或等圆中，同弧或等弧所对的圆周角相等，都等于这条弧所对的圆心角的一半．推论：半圆（或直径）所对的圆周角是直角，90°的圆周角所对的弦是直径．也考查了轴对称的性质．27.【答案】解：（1）∵二次函数y 1=x 2+bx +c 的图象C 1经过（-1，0），（0，-3）两点，∴．解得解得 ， ∴抛物线C 1的函数解析式为y =x 2-2x -3；（2）∵y 1=x 2-2x

【解析】（1）根据待定系数法，可得函数解析式；（2）根据抛物线平移的规律：向左平移加，向上平移加，可得答案； （3）根据函数与不等式的关系，可得答案．本题考查了二次函数与不等式组，函数图象平移的规律是：左加右减，上加下减；利用函数图象在上方的部分函数值大是解不等式组的关键．28.【答案】90； ；tan （90°90°--α） 【解析】解：连接AD ，∵AB=AC ，点D 是BC 的中点，∴∠ABC=∠C ，∠BAD=∠DAC=∠BAC ，AD ⊥BC ， ∵AD ⊥BC ，DE ⊥AC ， ∴∠ADE+∠CDE=90°，∠C+∠CDE=90°， ∴∠ADE=∠C ．又∵∠ADB=∠DEC=90°，∴△ADB ∽△DEC ， ∴=即AD•CE=BD•DE ．∵点D 是BC 的中点，点F 是DE 的中点，∴BD=BC ，DE=2DF ， ∴AD•CE═BC•2DF=BC•DF ， ∴=，又∵∠ADE=∠C ，∴△AFD ∽△BEC ， ∴=．在Rt △ADB 中，∵∠ABD=90°ABD=90°--∠BAD=90°BAD=90°--∠BAC ，BD=BC ，∴tan ∠ABD=tan （90°90°--∠BAC ）==，∴==tan （90°90°--∠BAC ）．∵△AFD ∽△BEC ，∴∠DAF=∠CBE ． ∵∠CBE+∠BOD=90°，∠AOH=∠BOD ， ∴∠DAF+∠AOH=∠CBE+∠BOD=90°， ∴∠AHO=180°AHO=180°-90°-90°-90°=90°=90°，即∠AHB=90°． （1）如图1，根据以上结论可得： ∠AHB=90°，=tan （90°90°--×90°）=．故答案分别为：90°、；（2）如图2， 猜想：∠AHB=90°，=．证明：根据以上结论可得： ∠AHB=90°，=tan （90°90°--×60°）=．（3）如图3，根据以上结论可得：=tan （90°90°--α）． 故答案为：tan （90°90°--α）． 连接AD ，根据等腰三角形的性质可得∠ABC=∠C ，∠BAD=∠BAC ，AD ⊥BC ，然后根据同角的余角相等可得∠ADE=∠C ．易证△ADB ∽△DEC ，可得AD•CE=BD•DE ．由此可得AD•CE=BC•2DF=BC•DF ，即=，由此可证到△AFD ∽△BEC ，则有=．在Rt △ADB 中根据三角函数的定义可得90°--90°--∠BAC）==，从而可得=tan（90°tan∠ABD=tan（90°∠BAC）．由△AFD∽△BEC可得∠DAF=∠CBE，即可得到∠DAF+∠AOH=∠CBE+∠BOD=90°，即可得到∠AHB=90°．利用以上结论即可解决题中的三个问题．本题主要考查的是相似三角形的判定与性质、三角函数的定义、等腰三角形的性质、同角的余角相等等知识，证到△AFD∽△BEC是解决本题的关键． 29.【答案】3； ；-1【解析】解：（1）点（2，3）和射线OA之间的距离为3，点（-2，3）和射线OA之间的距离为=，故答案分别为：3、；（2）∵直线y=x和双曲线y=之间的距离为，∴k＜0（否则直线y=x和双曲线y=相交，它们之间的距离为0）．过点O作直线y=x的垂线，与双曲线y=交于点A、B，过点B作BH⊥x轴，如图1，在Rt△OHB中，∠HOB=∠HBO=45°，OB=，则有OH=BH=OB=1，∴点B的坐标为（1，-1），∴k=1×（-1）=-1，故答案为：-1；（3）①过点O分别作射线OE、OF的垂线OG、OH，如图2，则图形M为：y轴的正半轴、∠GOH的边及其内部所有的点（图2中的阴影部分）；②图形W与图形N之间的距离为．提示：设抛物线y=x2-2与射线OG的交点为N，如图3，图形N上点的坐标可设为（x，x2-2），则图形W与图形N之间的距离为的最小值．易求出点N的坐标为（，-），从而有0≤x2≤，由此可得x2+（x2-2）2=（x2-）2+的最小值为（-）2+=，则图形W与图形N之间的距离为=．（1）只需根据新定义即可解决问题；（2）过点O作直线y=x的垂线，与双曲线y=交于点A、B，过点B作BH⊥x 轴，如图1，根据新定义可得直线y=x和双曲线y=之间的距离就是线段OB 的长，如何只需求出点B的坐标，运用待定系数法就可求出k的值； （3）①过点O分别作射线OE、OF的垂线OG、OH，如图2，根据新定义可得图形M为y轴的正半轴、∠GOH的边及其内部所有的点；②设抛物线y=x2-2与射线OG的交点为N，如图3，图形N上点的坐标可设为（x，x 2-2），根据新定义可得图形W与图形N之间的距离为的最小值．可通过求出点N的坐标得到x2的范围，然后利用二次函数的增减性求出x2+（x2-2）2=（x2-）2+的最小值，就可解决问题．本题属于新定义型，考查了用待定系数法求反比例函数的解析式、抛物线的增减性、勾股定理、求直线与抛物线的交点等知识，解决本题的关键是对新定义的理解．。

Science，Technology，Engineering and Math （SoSTEM）event on Wednesday January 21．Before SoS TEM started，I interviewed Charles Bolden．He was an astronaut （宇航员）and has been to space four times．"I enjoy watching young people take their ideas and turn them into reality，"he said．Next I spoke to Dr．Ellen Stofan．She spoke about her lifelong interest in science．When I was in the middle school，I knew I wanted to be a scientist，but I wasn't sure what kind，"she told me．As she grew up，she became interested in space．Her advice to young people who want to become a scientist is to"follow your dreams"．My third interview was with Megan Smith．She talked about encouraging more girls to step into STEM fields．She told me that women have always been part of amazing scientific discoveries，even though sometimes history records have left women out．Finally，I interviewed Kathy Pham，who is working to improve health care for more Americans through IT services．I asked her advice for young people who want a career （职业）in computer science．She advised kids to join in groups working on science and technology and to read more books on the subject．After the interview，we had a free talk．When I asked which technology careers were going to be most in need in the next 10years，Dr．Stofan noted that careers having something to do with energy sources are certainly going to be needed．My biggest take﹣away from the event was that the future holds many wonderful chances for people interested in STEM．Just as the computer scientist Kathy Pham said：Whatever your love is﹣whether it's clothing，space or cars一today you canfind a STEM field where you can do something you like．44．How many people did Linda interview before SoSTEM started？A．Three．B．Four．C．Five．D．Six45．When Dr．Stofan was young，she wanted to

event on January 25．D．There will be many chances for people interested in STEM．25．（8分）We all know that zebras have stripes （条纹）．But why？It's hard to get a black﹣and﹣white answer．This is a question not just common people like us have asked，but scientists too．Several studies have been done to find out the reason behind the stripes and many theories （理论）have been suggested．According to a recent study，the type of stripes changes depending on the temperature where zebras live．The warmer the place is，the more stripes they may have．From this study，scientists believe thatstripes may help to keep a zebra cool in warmer places．According to the cooler temperature theory，when air hits a zebra，the movements of air are stronger and faster over the black parts and slower over the white．This is because black color takes in more heat than white．So at the point where the black and white meet，there is cooling airflow．It can quickly cool a zebra's skin!In fact，scientists have noticed that heavily striped zebras have 5.4T lower skin temperature than other animals without stripes in the same area．Some scientists believe that stripes may be an adaptation （适应）by zebras to defend （防卫）themselves from the horseflies that follow zebras．The cooler temperature theory holds merit here too，since disease﹣carrying flies like horseflies like it hot．Flies also don't like landing on striped surfaces．There also have been many other theories that have been suggested for why zebras have stripes．Some explanations are very common．One of them is that stripes may help zebras hide in grass especially from lions．Lions are color blind and even if they are not far away they may see stripes as grey and be confused by them．What's more，zebras are a large group of animals living together．When a number of zebras stand or move together，stripes may confuse lions into thinking it is one large animal．48．Stripes are helpful for zebras to．A．stay coolB．move togetherC．live in cold placesD．fight against diseases49．How do zebras'stripes protect them from lions？A．Lions may be frightened away by strips．B．Lions may see stripes as many animals．C．Stripes can prevent zebras from being seen．D．Stripes may make lions confused．50．The underlined words"holds merit"in Paragraph 4probably mean""．A．works wellB．sounds unreasonableC．causes disagreementD．needs supporting facts51．What is the passage mainly about？A．Why lions can't eat zebras．B．How horseflies keep away from zebras．C．Why zebras have stripes．D．How animals adapt to nature．26．（8分）Entertainment （娱乐）is a developing business．Its popularity continues to grow as it keeps up with technology．More people are willing to pay for entertainment with their time and money．Sometimes entertainment is a form of escapism（逃避）．It takes us away from our reality and gets us into another world﹣not our own．•Why do we want to escape？Boredom or loneliness：The boredom of daily life gets to us and we feel we need some excitement and a bit change．A TV running in the background，and maybe catching our attention every now and then，keeps us company．Fear and avoidance：We don't want to face something we fear，or can't bring ourselves to move past the fear and do something about it．We're scared to go for what we want，so we choose to turn on the TV．Struggle：Life sometimes feels like a battle﹣traffic，work，taking care of ourselves and keeping up with what's going on．Al the end of the day all we want to do is forget about all of it and sit mindlessly in front of TV．Escaping has never been easier than today．We have many forms of escape．And the most favored is entertainment．•________Easy to reach and affordable：You can stay at home and watch TV，or surf online allday long．Social connection：one can line up for a new movie and socialize with other people or go to a ballgame and cheer for his or her favorite team．Entertainment has become something people have in common and can talk about．All forms of entertainment are okay if we know what we're doing．And more importantly，we have complete control over when entertainment comes to an end．•To face our fears and reality or to escape？If you tried escaping before and it didn't help，it's time to deal with the problems you face．Before watching a TV show，make sure that the important thing is taken care of．Leave your favorite show to the end of the day，after you've taken care of what matters to you．This will allow you to enjoy every minute．There is nothing wrong with entertainment，if we don't place a higher value on it than our own reality and what matters to us．When we entertain ourselves mindfully，we won't need to escape．We turn entertainment into the reality of the moment．And when we're done，we move on 一with no regret．And that can be a lot of fun．52．One reason why we want to escape is that．A．we are eager to get over our fearB．we prefer to sit mindlessly before TVC．people are willing to pay for their entertainmentD．people need some excitement and change in daily life53．Which of the following sentences might be the best to fill in the blank？A．Who can we socialize with？B．What's the best form of escapism？C．Why is entertainment in such great need？D．How does the entertainment business develop？54．Which of the following can explain the underlined sentence？A．We can stop entertaining when we want to．B．It's more important to control our daily life．C．Entertainment leads to the loss of self﹣control．D．We need to learn about all forms of entertainment．55．The writer may agree that．A．escape from life is more difficult than everB．entertainment is the best way for us to enjoy lifeC．the popularity of entertainment depends on technologyD．we can truly entertain ourselves with real matters done．七、五选五27．（10分）Following Their DreamsFlorence lived in the countryside of Kenya （肯尼亚）in Africa．When she was 12，she wanted nothing more than to finish school．But for many girls like her，school is not a choice．（56）．Families will probably spend money educating boys．Many girls are forced to marry．（57）．It was Beads for Education，started by Lisa Stevens，that helped realize her dream．Beads has provided many girls with the best education possible．Florence was the first of 320Kenyan girls in third grade．（58）．During her visit，she heard that many women made and sold baskets．They used the money to send their daughters to school．Two years later，she started to help sell the Kenyan crafts in the U．S．In 1998，Stevens began helping girls continue their education．（59）．In January，2015，she opened the fourth one．"I want to provide the girls with the best education possible and prepare them for college and beyond，"Stevens said．The new high school is named Tembea，which means"to walk"．Florence is walking toward a bright future．（60）．"Florence is the first in her family to finish highschool and college，"says Stevens．"She is an example for all girls in Kenya．"八、任务型阅读28．（10分）Our views towards life change over the time．When I was around five years old，I was in a car accident．At that time，I did not realize the seriousness of it and how lucky I was to still be alive．As I look back to think what happened on that night，I now realize how lucky my family members and I were to not have gotten serious injuries．The clay of the accident started out great．My brother，Troy and I had spent the night before at JoAnn's house，with Heather，and JoAnn's husband Gary．The next day we spent playing inside the house，because it was cold，windy and rainy outside．At night，JoAnn told us we were going out and that where we were going was a surprise．The five of us climbed into an old car，and we set off for our surprise．It was still cold，windy，and raining cats and dogs outside when we left．Troy，Heather and 1sat in the backseat together happily．The next thing I knew was that everything was chaos （混乱）!The road was so slick （滑的）that the car lost control．Glass was flying everywhere，and it sounded like there was noise all around us．Then it was totally quiet，except for the sound of the rain and wind．Troy，Heatlier and I were all lying on top of one another．The three of us were crying，not knowing what had happened．JoAnn and Gary were trying to calm （使平静）us down and kept asking us if we were all right．Luckily，none of us was injured，just a few cuts．After that I only remember sitting there in the cold，dark night waiting for Gary to get back with people to help us．We never got to the surprise that night．Bui at least we were ableto go home in one piece．After my brother and I got home that night，I remember my parents let us stay up as long as we wanted to．I guess my parents were realizing just how close they came to losing us that night．As I think of the tragedy （悲剧）that could have happened on that night，I realize how precious （宝贵）life is．I treasure my family and friends，and hope that we will share a loving，caring，and rewarding lifetime together．Things seldom go the way I plan them to，but I take a deep breath，try to laugh，and make the best of it．61．Did the accident happen at night？62．What was the weather like when the accident happened？63．How did the accident happen？64．What was the writer doing when Gary asked for help？65．What is the passage mainly about？．九、书面表达29．（15分）根据中文提示和英文海报内容，写出意思连贯、符合逻辑、不少于50词的短文，所给的英文提示词仅供选用．请不要出现真实的学校、班级和姓名．假如你叫李华，你的美国笔友想知道你有什么好的学习或生活习惯？你是如何养成这个习惯的？它跟你带来什么益处？请你根据他的问题回复邮件．1．What good habit do you have？2．How do you

阅读下面的文字,完成后面的题。
有些外国人颇为羡慕中国人有私章。
他们觉得在小小的一块石头上刻上自己的名姓,或阴或阳，或篆或籀,或铁线或九叠，都怪有趣的。
抗战时期，闻一多在昆明，以篆（zuàn）刻图章为副业，当时过境的美军不少，常有人登门造访,请求他的铁笔。
他照例先给对方起一个中国名字，告诉他们那几个中国字既是谐音，又有吉祥高雅的涵义。
对方已经乐不可支，然后就会约期取件,当然是按润例计酬.虽是（甲) ，却也不轻松，视石之大小软硬而用指力、腕力或臂力，积年累月地捏着一把小刀,伏在案上于方寸之地纵横排奡注,势必至于两眼昏花,肩耸背驼，手指磨损。
对于他，。
在字画上盖章，能使得一幅以墨色或青绿为主的作品,由于朱色印泥的衬托，而显得格外生动，有（乙）之妙.据说这种做法以酷爱文化的唐太宗为始,他有自书“贞观”二字的联珠印,嗣后唐代内府所藏的精品就常有“开元”“集贤"等钤记.一般而言，收藏家或鉴赏家在字画名迹上盖个图章原不是什么坏事，不过一幅完美的作品若是被别人在空白处盖上了密密麻麻的大小印章,却是（丙）。
最讨厌的是清朝的皇帝，动辄(zhé）于御题之外加盖什么“御览之宝”的大章,好像非如此不足以表示其占有欲的满足.最迂（yū）阔的是一些藏书印，如“子孙益之守勿失"、“子孙永以为好"、“子子孙孙永无鬻”之类,我们只能说其情可悯，其愚不可及。
明清以前，文人雅士篆刻之风大行,流落于市面的所谓闲章常有奇趣，或摘取诗句，或引用典实，或直写胸意.有时候还可于无意中遇到石质特佳的印章，近似旧坑田黄之类。
先君嗜金石篆刻，积有铜器铭文、碑石拓片很多,印章亦不少,丧乱中我仅携出数方,除“饱蠹楼藏书印”之外尽属附章.有一块长方形寿山石，刻诗一联“鹭拳沙岸雪，□□□□□”，不知是谁的句子，也不知何人所镌（juàn），我觉得对仗工,意境雅；书法是阳文玉筋小篆，尤为佳妙，我喜欢它文字凸起有棱、圆融秀丽之貌。
