D.They share the same contents.I work with Volunteers for Wildlife, a rescue and educationorganization at Bailey Arboretum in Locust Valley. Trying to help injured, displaced or sick creatures can be heartbreaking; survival is never certain. However, when it works, it is simply beautiful.I got a rescue call from a woman in Muttontown. She had found a young owl(猫头鹰) on the ground. When I arrived, I saw a 2-to 3-week-old owl. It had already been placed in a carrier for safety.I examined the chick(雏鸟) and it seemed fine. If I could locate the nest, I might have been able to put it back, but no luck. My next work was to construct a nest and anchor it in a tree.The homeowner was very helpful. A wire basket was found. I put some pine branches into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.Now all that was needed were the parents, but they were absent. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.A nervous night to be sure, but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded to the recordings. I drove over and saw the chick in thenest looking healthy and active. And it was accompanied in the nest by the greatest sight of all — LUNCH! The parents had done their duty and would probably continue to do so.24.What is unavoidable in the author’s rescue work according to paragraph 1A.Efforts made in vain.B.Getting injured in his work.C.Feeling uncertain about his future.D.Creatures forced out of their homes.25.Why was the author called to MuttontownA.To rescue a woman.B.To take care of a woman.C.To look at a baby owl.D.To cure a young owl.26.What made the chick calm downA.A new nest.B.Some food.C.A recording.D.Its parents.27.How would the author feel about the outcome of the event A.It’s unexpected.B.It’s beautiful.C.It’s humorous.D.It’s discouraging.You are given many opportunities in life to choose to be a victim or creator. When you choose to be a victim, the world is a cold and difficult place. “They” did things to you which caused all of your pain and suffering. “They” are wrong and bad, and life is terrible as long as “they” are around. Or you may blame yourself for all your problems, thus internalizing (内化) your victimization. The truth is, your life is likely to stay that way as long as you feel a need to blame yourself or others.Those who choose to be creators look at life quite differently. They know there are individuals who might like to control their lives, but they don’t let this get in the way. They know they have their weaknesses, yet they don’t blame themselves when they fail. Whatever happens, they have choice in the matter. They believe their dance with each sacred (神圣的) moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth.Victims and creators live in the same physical world and deal with many of the same physical realities, yet their experience of life is worlds apart. Victims relish (沉溺) in anger, guilt, and other emotions that cause others- -and even themselves--to feel likevictims, too. Creators consciously choose love, inspiration, and other qualities which inspire not only themselves, but all around them. Both victims and creators always have choice to determine the direction of their lives.In reality, all of us play the victim or the creator at various points in our lives. One person, on losing a job or a special relationship, may feel as if it is the end of the world and sink into terrible suffering for months, years, or even a lifetime. Another with the same experience may choose to first experience the grief, then accept the loss and soon move on to be a powerful creative force in his life.In every moment and every circumstance, you can choose to have filler, richer life by setting a clear intention to transform the victim within, and by inviting into your life the powerful creator that you are.28.What does the word “They” in paragraph 1 probably refer to A.People and things around you. B.Opportunities and problems. C.Creators and their choices. D.Victims and their sufferings. 29.According to Paragraph 2, creators ________.A.seem willing to experience failures in life B.possess the ability to predict future lifeC.handle ups and downs of life wisely D.have potential to createsomething new30.The examples mentioned in Paragraph 4 show that ________. A.different reactions to sufferings lead to different life paths. B.people need family support to deal with challengers in life. C.it takes creators quite a long time to get rid of their pains. D.one’s experiences determine his attitude toward life. 31.What is the author’s purpose in writing this passageA.To define victims and creators.B.To evaluate victims against creators.C.To explain the relationship between victims and creators. D.To suggest the transformation from victims to creators.Why do some men settle down to form families with the mothers of their children, and others don’t Biology plays a role. Work published by Lee Gettler of the University of Notre Dame, in Indiana, clarifies how testosterone, the principal male hormone (荷尔蒙), operates.Previous studies suggest that high levels of testosterone are bad for family life. Fathers with lower testosterone levels provide more child care while high-testosterone males are less likely to stick around. Dr. Gettler has shown something further. This is that a man’s adult testosterone level seems correlated with whether his father was present during his teenage years.His data come from a survey begun in the Philippines in 1983. This monitored the health and nutrition of 966 men enrolled as babies. It also collected extensive information on whether the fathers of these men were around and providing parental care in the households. It further documented whether participants got married, had children and whether they participated in child care. Crucially, it also measured their testosterone levels at the ages of 21, 26 and 30.Overall, Dr. Gettler and his colleagues found that on becoming fathers, men had lower testosterone levels if their own fathers had been involved in their care during their teenage years. It has two possible explanations. One is that it is directly genetic (基因的). The other is that teenage experience actually modulates (调节) testosterone levels. This explanation, which Dr. Gettler favors, could lead to high-testosterone men abandoning their sons, who thus become high-testosterone in their turn.He also found some of those in the survey whose fathers were absent during their adolescence, and who ended up with high levels of the hormone, did become caring fathers. Why this pattern should exist is an unanswered question. But a zoologist looking at these data might take it as an example of developmental plasticity (可塑性), in which the same genes produce different, butappropriate, outcomes in different circumstances.Dr. Gettler’s discovery throws a useful light on the problem of fatherless families,and how to try to end it.32.What is Gettler’s study mainly aboutA.Family life. B.Fathers’ roles.C.Adult testosterone. D.Child care.33.What can be learnt about Dr. Gettler’s studyA.It was conducted among babies.B.The finding is far from satisfactory.C.The data used were relatively reliable.D.It monitored the nutrition of participants.34.Why is the zoologist mentioned in the passageA.To suggest a follow-up study.B.To contradict Gettler’s ideas.C.To point out the study limitations.D.To give a possible explanation.35.Which of the following is a suitable title for the textA.Like Father, Like SonB.Caring Father, Happy SonC.Good Father, Good SonD.Love Me, Love My SonTechnology is here to stay. 36 . However, they are often unsure onhow to help children use technology responsibly and keep a balance between online and offline time. Here are some tips. Have a device contractHaving a device usage contract allows parents and children to work through what responsible technology usage looks like in your family and ensure that everyone is aware. 37 . Kids are more likely to make sense of the reasons you have for restriction.38Although this tip seems like common sense, it is often difficult due to the demand of work and the expectation of being constantly connected. By ensuring you build offline time into your own day and communicate that with your children, they will see the value and benefits. Whether you are reading a book or just taking a walk, letting your children be aware of your offline actions will encourage them to do the same!Encourage non-tech activitiesOne great way to keep kids off their screens is to ensure that they have other activities to fill their time. 39 . These activities are also great ways to help children to develop their social skills and confidence.Tech-free family timeOnce a week, pencil-in a “tech-free family time” in your schedule. Itcan be a meal or trip. To help increase the success of outings, try designing special activities, i. e., going to the beach to build a sand castle that looks the same as a photo you have found online. 40 A.Model good technology useB.Communicate with childrenC.A little extra planning goes a long wayD.The contract is helpful to the settlement of conflicts E.Parents are seeing more technology in their homes and jobs F.Also, drafting the contract together promotes understanding G.This can come in a variety of forms: soccer, fencing and more 三、完形填空My first caregiving experience involved driving 180 miles every day to see my grandmother who was terminally ill. I was certainly 41 as the weeks turned into months, but the desire to 42 my grandmother in her last days was overwhelming (无法抗拒的).

You play as the “mother” of afrog who lives alone and enjoys traveling. You need to prepare food and tools for his trips. The frog will send you postcards while he is away.The game’s popularity may have something to do with how lonely people are these days, according to the Xinhua News Agency. Many players have said that the lonely frog is just like them. But playing with the frog helps them forget their loneliness for a short time.Loneliness seems to be a common problem today. According to the Guardian, a British daily, about 40 percent of American adults say they’re lonely. And in the UK, about one in five people in the country are “always or often lonely”, the Telegraph reported.This might be why the UK governm ent announced the country’s very first “Minister of Loneliness” (孤独大臣) in January. The minister’s job is to find ways to help UK citizens feel less lonely. The minister’s office will provide more money for activities that connect people together.This loneliness problem may be partly because of social media. When we see pictures of friends having fun or posting pictures on WeChat or Microblog, we may compare their “perfect” lives with our own and feel sad and lonely.But we should remember that no one is bo rn to be lonely. As UK poet John Donne once wrote, “No man is an island. Every man is a piece of the land, a part of the main.” Here are some tips to get rid of loneliness:Sing your favorite songs.Connect with a friend.Do something creative, such as drawing a picture.Imagine some place you’d like to visit, like a fun gathering or a sporting event.1.What do players do while playing Travel Frog?A.Build houses for their frogs. B.Write postcards to their frogs.C.Choose places for their frogs to travel. D.Prepare food and tools for their frogs’ trips.2.According to the passage, why is the game so popular?A.Because the frog is lovely. B.Because it can be played on mobile phones.C.Because it makes people feel less lonely. D.Because people have more spare time now.3.To deal with the problem of loneliness, the UK government .A.designed the game Travel Frog B.named the “Minister of Loneliness”C.held parties for people to get together D.stopped people’s use of social media4.What can we learn from the last paragraph?A.Everyone is connected with others. B.We should not compare ourselves to others.C.It’s not fun to feel lonely. D.We should be away from social media.B14、Japanese children are so happy because they have three festivals each year. Besides Boy's Day, they also have Girl's Day and the 7-5-3 Festival.May 5th is Japanese Children's Day. But since the festival is mainly celebrated by boys, it is usually called Boy's Day. On Boy's Day, children don't have to go to school. Each family with a boy hangs up huge carp-shaped flags. The flags are usually with three colors: black (standing for the father), red (standing for the mother) and blue (standing for the son ). Japanese parents believe that the flags will bring their boys good luck and give them courage and power.Girl's Day is a girls' festival on March 3rd. It is also called the Doll's Festival because on that day, families get a set of dolls at home for their daughters. It is celebrated because the parents want their children to be strong and healthy.The 7-5-3 Festival is for children aged three, five and seven. Japanese people think that these three ages are the luckiest ones in one's life. On that day, these children get special candies wrapped (包裹) in beautiful bags.

You, too? I thought I was the only one." Have you ever said this to someone? If so, you may have ended up becoming friends with this person.It seems that similarity often helps from friendships. The Greek philosopher (哲学家) Aristotle once said, "Some define (下定义) it (friendship) as a matter of similarity; they say that we love those who are like ourselves."Now, there is some science behind this idea. Scientists from University of California said friends have similar brains, Scientific America reported.The scientists invited 42 university students to take part in an experiment. Each student watched the same set of videos, which included a comedy, a debate (讨论) and a soccer match. At the same time, scientists scanned(扫描) their brains and recorded their brain activity.Similar parts of their brains became active while watching the videos, especially parts that are connected with motivation (动力), learning and memory. According to their scans, friends who watched the same videos parts reacted in similar ways. However, people who weren't friends has different reactions to the same video parts.Having close friends whose brain react like ours may be useful because it makes one's own value, opinions, and interests stronger, lead scientist Carolyn Parkinson told Business Insider.But brain similarity is not the only thing that can result in friendship. Scientists from the University of Leipzig, Germany, found that friendship is also based on how physically close you are to someone. They did an experiment with first-year college students who met in class for the first time. Is this experiment, students who sat in neighboring seats were more likely to become friends.1.What does "this idea " in Paragraph 3 refer to ?A.Many friendships start with small chats B.Friends try to develop similarities between themselves.C.People with similarities may become friends D.We like those who like us first.2.What did the scans of the students' brain show?A.They had watched the same video partsB.Friends had similar reactions to the same video partsC.Watching videos improves one's memoryD.It's good to have friends who react similarly3.According to the story, what else may help build friendship?A.Being fun and helpful B.Studying at the same collegeC.Having similar appearance D.Being physically closeE17、On September 13th, I woke up in the best mood.

I got ready, danced in my room to my favorite music while I picked out my clothes, made my lunch, and was on my way to school. I arrived at 9: 50 a. m. Little did I know, in the next 20 minutes, my life would change forever. As I got out of my classroom, there he was, holding the gun.Although everything happened so fast, in a matter of about 4 minutes, I remember it clearly. I remember every face I saw, and I remember every sound I heard. I remember the fear and the panic of the unknown. And lastly, I remember running. Running for my life. I ran down the stairs, out of the school’s front doors, and down the street to the primary school. I remember looking down at my feet. As I looked down I thought to myself, “ How am I running so fast?”I finally made it to a safe classroom, and 20 other students and I settled in for lockdown. We stayed close to one another and cried. It felt as though the tears going down our faces would never stop. We passed our phones around to text our loved ones that we were safe and that there was a school shooter, shots were fired, and 4 students were injured thus far.The lockdown lasted about 30 minutes, even though it felt like forever.

Amazing, but true. The sheep is15percent human and 85 percent sheep. The breakthrough(突破)makes it possible to use animal organs in human bodies in the future. Professor Esmail Zanjani of University of Nevada, US, has spent seven years And over $9 million on the work. Zanjani took stem cells(干细跑) from the human body and put them into the sheep while it was still in its mother’s body. The stem cells made other cells that grew into organs. Zanjani believe that in the future such sheep might be used to help humans. Two months later a human-sheep is born, it has a liver(肝脏), heart, ling(肺) and brain that are part-human. These organs could be used to help people in need of them. There are different opinions about his work, however. Some say that scie ntists don’t have the right to create new creature(生物). Using animal organ might bring animal viruses(病毒) into human bodies. Others are afraid that the work might change sheep. But Professor Anjani has said that this is impossible.1.According to the passage, we know that the first human-sheep looks like________.A.a sheep B.a goatC.a cat D.an elephant2.The appearance(出现) of the first human-sheep means_________.A.sheep will be cleverer and stronger in the futureB.sheep are as important as human in the futureC.sheep will take the place of humans in the futureD.animal organs may be used in human bodies3.Some people think it’s not good to use animal organs because they’re afraid that _____A.humans will change into animalsB.There will be fewer and fewer animals in the futureC.the organs may bring animal viruses into human bodiesD.many animals will be dead after they give their organs to humans4.. Zanjani put some stem cell from the human body and put them into the sheep while it was still in its mother’s body. He “____________” .A.created a new stem cell B.created a new creatureC.created a new organ D.created a new food5.According to the passage, “__________” is not true.A.The world’s first human-sheep is 15% percent human and 85% sheepB.The world’s first human-sheep has many organs that are part-humanC.Zanjani created the world’s first human-sheep to make the sheep grows fasterD.The world’s first human-sheep is a sheep with the body of a sheep and half-human organs.Ⅴ.书面表达19、书面表达假如你们学校正在开展研究性学习(exploring learning strategies),请你根据下表提供的信息,写一篇短文,让更多的学生了解你校开展研究性学习的一些情况。

={x x ≥4或x ≤0}∩{x x >4或x ≤-2}={x x >4或x ≤-2}.由题意可知阴影部分对于的集合为∁U A ∩B ∩A ∪B ,所以∁U A ∩B ={x -2<x ≤4 ,∁U A ∩B ∩A ∪B ={x -2<x ≤0或x =4}.故选:D .2.C【详解】因为复数z 满足:z 2-2z +2=0,即(z -1)2=-1,故z =1+i 或z =1-i ,因为复数z 所对应的点在第四象限,故复数z =1-i ,所以z 2=-2i. 故选:C .3.C故a +2b 2=a 2+4b 2+4a ⋅b =29,而又已知a ⋅b =-24,且a =b ,所以a 2+4a 2-96=29,解得a =5.故选:C4.A【详解】以抛物线的顶点为坐标原点建立平面直角坐标系如下图所示,设F p2,0,则抛物线上一点的坐标为p 2+40,30,代入抛物线方程y 2=2px p >0 得302=2p p 2+40 ,解得p =10,p 2=5,所以光源到反射镜的顶点的距离为5cm.故选:A5.C【详解】因为函数f x =a -1 x x -b +1 为R 上的奇函数,且递减,所以a -1≠0且f -1 =-f 1 ,即-a -1 -b =-a -1 2-b ,所以-b =2-b ,解得b =1,经检验符合题意,故f x =a -1 x x =a -1 x2,x ≥0-a -1 x 2,x <0因为函数f x =a -1 x x 在R 上为减函数,所以a -1<0,所以a <1.故选:C .6.A【详解】对于∀x 0∈R ,设a n =f nx 0 n ∈N ∗,则a 1=f 1x 0 =f x 0 =3x 0+2,且a n +1=3a n +2,所以a n +1+1=3a n +3=3a n +1 ,所以a n +1 是以3x 0+3为首项,公比为3的等比数列.a n +1=f nx 0 +1=3x 0+3 3n -1=3n x 0+3n ,即f nx 0 =3n x 0+3n -1.所以f nx =3n x +3n -1,故选:A .7.A【详解】设AB =AF 2 =m ,AF 1 =AF 2 +2a =m +2a ,BF 1 =BF 2 -2a =2m -2a ,BF 12+BA 2=AF 1 2,BF 1 2+BF 2 2=F 1F 2 2,2m -2a 2+m 2=m +2a 2①,2m -2a 2+4m 2=4c 2②,由①可得m =3a ,代入②式化简得:13a 2=c 2,∴12a 2=b 2,∴ba=23,所以双曲线的渐近线方程为y =±bax =±23x .故选:A8.B【详解】由2m 2-22sin x +π4⋅m +sin2x ≤0,得m 2-sin x +cos x ⋅m +sin x ⋅cos x ≤0,即m -sin x m -cos x ≤0,由几何意义可知,函数y =m 的图像在函数y =sin x ,y =cos x 的图像之间,如下图所示,-22≤m ≤22,要使b -a 达到最大,仅需要m =-22或m =22,此时b -a =π4--3π4=π.故选:B .9.BD【详解】由f (x )+g (x )=2x 得f (-x )+g (-x )=2-x ,由于函数f (x )和g (x )分别为奇函数和偶函数,所以-f (x )+g (x )=2-x,因此f x =2x -2-x 2,g x =2x +2-x 2,对于A , f (x )-g (x )=-2-x ,故A 错误,对于B ,由于函数y =2x 在(-∞,+∞)单调递增,y =2-x在(-∞,+∞)单调递减,所以f x =2x -2-x 2在(-∞,+∞)单调递增,故B 正确,对于C ,fx =2x ln2+2-x ln22=2x +2-xln22≥22x ×2-x ln22=ln2,当且仅当x =0时取等号,而ln2<1,所以C 错误,对于D ,g x =2x +2-x 2≥22x ×2-x2=1,当且仅当x =0时取等号,所以D 正确,故选:BD 10.ACD【详解】对于A ,极差为4-0=4,中位数为1+22=32,所以极差与中位数之积为4×32=6,A 对;对于B ,根据方差的性质可知,数据4x 1-1,4x 2-1,⋯,4x n -1的方差是42×5=80,B 错;对于C ,由方差s 2=1n x 1-x 2+x 2-x 2+⋯x n -x 2 =0,可得x 1=x 2=⋯=x n =x,即此组数据众数唯一,C 对;对于D ,∵x 1+x 2+⋯+x n n =x 0,∴x 1+x 2+⋯+x n =nx 0,∴x 0+x 1+x 2+⋯+x n n +1=x 0+nx 0n +1=x 0,D 对.故选:ACD11.BCD【详解】对于A ,因为f x +1 是奇函数,所以f -x +1 =-f x +1 ,故A 错误;因为f x +1 是奇函数,所以y =f x 的图象关于点1,0 对称,即有f x =-f 2-x ,所以g 2-x =1-2-x f 2-x =x -1 f 2-x =(1-x )f (x )=g x ,所以y =g x 的图象关于直线x =1对称,函数g x 在x ∈1,+∞ 上单调递增,所以g x 在x ∈-∞,1 上单调递减,故B 正确;因为a <2-b <1,所以g 1 <g 2-b <g a ,即g 1 <g b <g a ,故C 正确;因为g a >g a +1 ,且a <a +1,由函数y =g x 的图象关于直线x =1对称,得a +a +12<1,解得a <12,故C 正确.故选:BCD .12.ABD【详解】取圆台的轴截面ABCD ,设AD 、BC 的中点分别为O 1、O 2,连接O 1O 2,分别过点A 、D 在平面ABCD 内作AE ⊥BC ,DF ⊥BC ,垂足分别为点E 、F ,由题意可知,O 1O 2与圆台的底面垂直,易知四边形ABCD 为等腰梯形,且AB =CD =3,AD =2,BC =4,在△ABE 和△DCF 中,AB =DC ,∠ABE =∠DCF ,∠AEB =∠DFC =90°,所以,△ABE ≌△DCF ,所以,BE =CF ,因为AD ⎳BC ,AE ⊥BC ,DF ⊥BC ,则四边形ADFE 为矩形,且EF =CD =2,同理可证四边形AEO 2O 1为矩形,则O 1O 2=AE ,且AE ⎳O 1O 2,所以,AE 与圆台的底面垂直,则圆台的母线与底面所成的角为∠ABE ,所以,BE =CF =AB -EF 2=4-22=1,则AE =AB 2-BE 2=32-1=22,所以,tan ∠ABE =AEBE=22,A 对;对于B 选项,圆台的全面积为π×12+π×22+π×1+2 ×3=14π,B 对;对于C 选项,易知圆台的外接球球心在梯形ABCD 内,且CE =BC -BE =4-1=3,由勾股定理可得AC =AE 2+CE 2=8+9=17,且sin ∠ABE =AE AB=223,所以,圆台的外接球直径为2R =AC sin ∠ABE =17223=3344,则R =3348,B 错;对于C 选项,将圆台沿着轴截面ABCD 切开,将圆台的侧面的一半展开如下图所示:延长BA 、DC 交于点M ,在圆台的轴截面等腰梯形ABCD 中,AB ⎳CD 且AB =12CD ,易知A 、D 分别为BM 、CM 的中点,所以,AM =DM =AB =3,设∠AMD =θ,则AD =3θ=π,则θ=π3,在△ACM 中,AM =3,CM =6,∠AMD =π3,由余弦定理可得AC =AM 2+CM 2-2AM ⋅CM cos π332+62-2×3×6×12=33,因此,从点A 经过圆台的表面到点C 的最短距离为33,D 对.故选:ABD .三、填空题:共4小题,每小题5分,满分20分.13.0.5114. 13π(cm )15. 416. 3-1或6313.0.51【详解】记事件A 1为“钥匙掉在宿舍里”,A 2为“钥匙掉在教室里”,A 3为“钥匙掉在宿舍里”,事件B 为“找到钥匙”,由全概率公式得P (B )=P (A 1)P B A 1 +P (A 2)P B A 2 +P (A 3)P B A 3 =0.5×0.8+0.3×0.3+0.2×0.1=0.5114.13π(cm )【详解】根据题意,从圆柱底部M 点绕圆柱体的侧面旋转4圈到达顶部的N 点,沿MN 将侧面展开后,最短路程,如图所示,其中矩形的高等于圆柱的高5πcm ,矩形的宽等于圆柱的底面圆的周长的4倍,即4×2π×32=12πcm ,所以蜗牛爬行的最短路径为MN =(5π)2+(12π)2=13π(cm ).故答案为:13π(cm ).15.4【详解】设地震强度为x ,则地震级别为f (x )=lg x ,由题意可令lg x =8.9,lg t =8.3,则lg x -lg t =8.9-8.3=0.6,由于lg2≈0.3,故lg x -lg t =2lg2=lg4,∴lg x t =lg4,xt=4,即日本1923年地震强度是8.3级的4倍,故答案为:416.3-1或63【详解】不妨设椭圆方程为x 2a 2+y 2b2=1(a >b >0),因为△OAB 是以半焦距为边长的正三角形,根据椭圆的对称性,可知AB 平行于x 轴或AB 平行于y 轴;当AB 平行于x 轴时,A ,B 关于y 轴对称,不妨设点A 在第一象限,所以∠AOx =60°,OA =c ,所以A c 2,3c 2 ,所以c 24a 2+3c 24b2=1,即c 2(a 2-c 2)+3a 2c 2=4a 2(a 2-c 2),所以c 4-8a 2c 2+4a 4=0,即e 4-8e 2+4=0,解得e 2=4-23或e 2=4+23(因为0<e <1,故舍去),所以e =3-1;当AB 平行于y 轴时,A ,B 关于x 轴对称,所以∠AOx =30°,OA =c ,不妨设点A 在第一象限,所以A 3c 2,c 2 ,所以3c 24a 2+c 24b2=1,即3c 2(a 2-c 2)+a 2c 2=4a 2(a 2-c 2),即3c 4-8a 2c 2+4a 4=0,所以3e 4-8e 2+4=0,而0<e <1,解得e 2=23或e 2=2(舍去),故e =63,所以椭圆的离心率为3-1或63,故答案为:3-1或63四.解答题(共6小题)17.【详解】(1)由a n +13a n =1+1n ,得a n +1n +1=3×a n n,------------2分又a 11=1,∴a n n 是以1为首项,3为公比的等比数列,------3分∴an n=3n -1,a n =n ×3n -1,即数列a n 的通项公式为a n =n ×3n

所成角的正弦值为2613-------12分19.【详解】(1)因为抛物线C 的焦点F 到准线l 的距离为2,所以p =2,----------2分根据建系方案的不同,抛物线的标准方程有四种可能,分别是y 2=4x ,y 2=-4x ,x 2=4y ,x 2=-4y .------------------4分(2)在平面直角坐标系中,抛物线的位置并不影响FP AB的取值,因此不妨取抛物线的方程为y 2=4x ,此时焦点F 1,0 ,根据题意,直线AB 的斜率存在且不为0,因此设直线AB 的方程为x =my +1,---5分与抛物线y 2=4x 联立,得关于y 的一元二次方程y 2-4my -4=0,-----------6分则Δ=16m 2+16>0,设A x 1,y 1 、B x 2,y 2 ,则y 1+y 2=4m ,y 1y 2=-4,y 1-y 2 =16m 2+16,-----------7分x 1+x 2=m y 1+y 2 +2=4m 2+2,-----------------------8分则AB =1+m 2y 1-y 2 =41+m 2 ,--------------------9分线段AB 的中点坐标为2m 2+1,2m ,中垂线方程为y -2m =-m x -2m 2-1 ,令y =0,解得x =3+2m 2,即中垂线与x 轴交于P 3+2m 2,0 ,---------10分所以FP =2+2m 2,------------------------11分则FP AB=12.-------------------------------12分20.【详解】(1)由题意得BQ =20m ,QC =10m ,∠B =∠C =π4,∵∠MQN =π2,∠BAC =π2,四边形内角和等于2π,所以∠AMQ +∠ANQ =π,又∠AMQ +∠BMQ =π,∠ANQ +∠CNQ =π,--------------------1分∴∠CNQ +∠BMQ =π,sin ∠CNQ =sin ∠BMQ ,-------------------------2分在△BMQ 中,由正弦定理得MQ sin B =BQ sin ∠BMQ,-------------------------3分在△CQN 中,由正弦定理得NQ sin C =CQ sin ∠CNQ,--------------------4分∴MQ NQ =BQ QC=2,证毕;-------------------------5分(2)由题意得AB =AC =152m ,故S △ABC =12AB ⋅AC =225m 2,-----------6分∵∠MQN =π2,∠NQC =θ,∴∠BQM =π2-θ,∴∠C =π4,∴∠QNC =3π4-θ,-------------7分设QN =xm ,则QM =2xm ,在△CQN 中,由正弦定理得NQ sin C =CQ sin ∠CNQ,即x sin π4=10sin 3π4-θ ,解得x =10sin π4sin 3π4-θ =52sin 3π4-θ ①,-------8分由三角形面积公式得S △CNQ =12CQ ⋅QN sin ∠CQN =5x sin θ,S △BMQ =12BQ ⋅QM sin ∠BQM =20x sin π2-θ =20x cos θ,--------------------9分故S △CNQ +S △BMQ =5x sin θ+20x cos θ=12S △ABC =2252,∴x =452sin θ+4cos θ②,--------10分由①②得52sin 3π4-θ =452sin θ+4cos θ ,化简得sin θ+4cos θsin θ+cos θ=92,-----------11分分子分母同除以cos θ得tan θ+4tan θ+1=92,解得tan θ=-17---------12分21.【详解】(1)X 的取值可能为1,2,3,4,5,6.--------1分P (X =1)=P (X =6)=12 5=132,P (X =2)=P (X =5)=C 15×12×12 4=532,P (X =3)=P (X =4)=C 25×12 2×12 3=516.------------------2分因为Y =|20-5X |,所以Y 的取值可能为0,5,10,15.P (Y =0)=P (X =4)=516,P (Y =5)=P (X =3)+P (X =5)=1532,P (Y =10)=P (X =2)+P (X =6)=316,P (Y =15)=P (X =1)=132.----------3分Y 的分布列为Y051015P 5161532316132E (Y )=0×516+5×1532+10×316+15×132=7516≈4.7,----------------------4分则顾客玩一次游戏,立减金额的均值约为4.7元,又该商品成本价是10元,所以该商品的最低定价约为15元.----------------------------5分(2)由(1)得P (X =3)=516.进行79次试验,设小球落入3号球槽的个数为ξ,则ξ~B 79,516.----------6分P (ξ=k )P (ξ=k -1)=1+(79+1)×516-k k 1-516 =1+25-k 11k 16.------8分当k <25时,P (ξ=k )P (ξ=k -1)>1,即P (ξ=k )>P (ξ=k -1);------------9分当k =25时,P (ξ=k )P (ξ=k -1)=1,即P (ξ=k )=P (ξ=k -1);-----------10分当k >25时,P (ξ=k )P (ξ=k -1)<1,即P (ξ=k )<P (ξ=k -1).------------------11分所以当k =25时,P (ξ=25)=P (ξ=24),此时这两项概率均为最大值.故3号球槽中落入24或25个小球的概率最大.--------------------------12分22.【详解】(1)由题意可知,f x 的定义域为0,+∞ ,f x =-ln x +2ax .令f x =0,可得2a =ln x x ,-------------1分令ℎx =ln x x x >0 ,ℎ x =1-ln x x2,令ℎ x =0得x =e ,----------2分当0<x <e 时,ℎ x >0,当x >e 时,ℎ x <0,可知ℎx 在0,e 上单调递增,在e ,+∞ 上单调递减,--------3分所以ℎx max =ℎe =1e,又当0<x <1时,ℎx <0,当x >1时,ℎx >0,根据以上信息,作出ℎx 的大致图象,-----------4分则由题意可知y =2a 与函数ℎx 的图象有两个不同的交点,∴2a ∈0,1e ,∴a ∈0,12e.-----------------5分(2)当a =1时,f x =-x ln x +x 2+x ,由2k x -2 +f x <g x 得2k x -2 <x ln x +x ,因为x >2,所以2k <x ln x +x x -2.----------------------------------6分设F x =x ln x +x x -2x >2 ,则F x =x -4-2ln x x -22,------------7分令m x =x -4-2ln x x >2 ,则m x =1-2x>0,所以m x 在2,+∞ 上单调递增,------------------------------------8分又m 8 =4-2ln8<4-2ln e 2=0,m 10 =6-2ln10>6-2ln e 3=0,所以m x 在8,10 上有唯一的零点x 0,即x 0-4-2ln x 0=0,--------------9分当2<x <x 0时,m x <0,即F x <0,当x >x 0时,m x >0,即F x >0,所以F x min =F x 0 =x 0ln x 0+x 0x 0-2=x 01+x 0-42 x 0-2=x 02,---------------------10分所以2k <x 02,又x 0∈8,10 ,所以x 02∈4,5 ,-------------11分又k ∈N *,所以k 的最大值为2.----------------12分。
