(0,1) 16. 2三、解答题17. 解 设等差数列{a n }的公差为d . 因为a 3+a 7=a 4+a 6=-4,a 3a 7=-12,所以a 3,a 7是方程x 2+4x -12=0的两根.因为d >0,所以a 3<a 7.解方程,得⎩⎪⎨⎪⎧ a 3=-6,a 7=2.由a 7=a 3+4d ,得d =2. 所以a n =a 3+(n -3)d =-6+2(n -3)=2n -12.18. (1)解 f ′(x )=1+2ax +b x . 解得⎩⎪⎨⎪⎧ a =-1,b =3.(2)证明 因为f (x )的定义域为(0,+∞),由(1)知f (x )=x -x 2+3ln x . 设g (x )=f (x )-(2x -2)=2-x -x 2+3ln x ,则g ′(x )=-1-2x +3x =-x -x +x .当0<x <1时,g ′(x )>0,当x >1时,g ′(x )<0.所以g (x )在(0,1)上是增加的,在(1,+∞)上是减少的.而g (1)=0,故当x >0时,g (x )≤0,即f (x )≤2x -2.19. (1)证明:∵a n +S n =n , ① ∴a n +1+S n +1=n +1. ②②-①得a n +1-a n +a n +1=1,∴2a n +1=a n +1,∴2(a n +1-1)=a n -1,∴a n +1-1a n -1=12,∴{a n -1}是等比数列.首项c 1=a 1-1,又a 1+a 1=1,∴a 1=12,∴c 1=-12,公比q =12. 又c n =a n -1,∴{c n }是以-12为首项,公比为12的等比数列.(2)由(1)可知c n =⎝ ⎛⎭⎪⎫-12·⎝ ⎛⎭⎪⎫12n -1=-⎝ ⎛⎭⎪⎫12n, ∴a n =c n +1=1-⎝ ⎛⎭⎪⎫12n.20. 解 (1)设等差数列{a n }的首项为a 1,公差为d .因为a 3=7,a 5+a 7=26,所以⎩⎪⎨⎪⎧ a 1+2d =7,2a 1+10d =26, 解得⎩⎪⎨⎪⎧ a 1=3,d =2.所以a n =3+2(n -1)=2n +1, S n =3n +n n -2×2=n 2+2n .(2)由(1)知a n =2n +1,所以b n =1a 2n -1=1n +2-1=14·1n n +=14·⎝ ⎛⎭⎪⎫1n -1n +1,所以T n =14·(1-12+12-13+…+1n -1n +1)=14·(1-1n +1)=nn +,即数列{b n }的前n 项和T n =nn +.21. 解析: (1)f ′(x )=x 2-2ax +a 2-1, ∵x =1是f (x )的极值点,∴f ′(1)=0,即a 2-2a =0,解得a =0或2.(2)∵(1,f (1))在x +y -3=0上.∴f (1)=2,∵(1,2)在y =f (x )的图像上,∴2=13-a +a 2-1+b ,又f ′(1)=-1,∴1-2a +a 2-1=-1, ∴a 2-2a +1=0,解得a =1,b =83,∴f (x )=13x 3-x 2+83,f ′(x )=x 2-2x ,由f ′(x )=0可知x =0和x =2是f (x )的极值点.∵f (0)=83,f (2)=43,f (-2)=-4,f (4)=8,∴f (x )在区间[-2,4]上的最大值为8.22. 解:(1)∵f ′(x )=1-ln xx 2-1, 令f ′(x )=0,得x 2=1-ln x .显然x =1是上面方程的解.令g (x )=x 2+ln x -1,x ∈(0,+∞), 则g ′(x )=2x +1x >0,∴函数g (x )在(0,+∞)上单调递增. ∴x =1是方程f ′(x )=0的唯一解. ∵当0<x <1时,f ′(x )=1-ln xx 2-1>0; 当x >1时,f ′(x )<0.∴函数f (x )在(0,1)上单调递增,在(1,+∞)上单调递减.(2)由(1)知函数f (x )在(0,1)上单调递增,在(1,+∞)上单调递减. 故①当0<2m ≤1,即0<m ≤12时,f (x )在[m,2m ]上单调递增.∴f (x )max =f (2m )=ln 2m2m -2m .②当m ≥1时,f (x )在[m,2m ]上单调递减,∴f (x )max =f (m )=ln m m -m . ③当m <1<2m ,即12<m <1时,f (x )max =f (1)=-1.。

AMy house is made out of wood, glass and stone. It is also made out of software.If you come to visit, you may be surprised when you come in. Someone will give you an electronic PIN (个人身份号码)to wear. This PIN tells the house who and where you are. The house uses this information to give you what you need. When it’s dark outside, the PIN turns on the lights nearest you, and then turns them off as you walk away from them. Music moves with you too. If the house knows your favorite music, it plays it. The music seems to be everywhere, but in fact ,other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.Of course, you are also able to tell the house if you want something. There is a home control console (控制台), a small machine that turns things on and off around you.The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you my car keys, you can use my car. The car works for you because you have the keys. My house works for you because you wear the PIN or hold the console.I believe that ten years from now, most new homes will have the systems that I’ve put in my house. Maybe the systems will be even bigger and be tter than the ones I’ve put in today. I like to try new ideas. I know that some of my ideas will work better than others. But I hope that one day I will stop thinking of these systems as new, and instead ask myself, “How will I live without them?”21.What does the passage mainly discuss?A. How to develop a new system.B. The function of the PIN.C. Easy life in the future.D. A home for the future.22.What’s the purpose when the writer wrote the fourth paragraph?A. To explain more easily what the functions of thePIN and the console are.B. To let readers know how special his house is.C. To explain the importance of the PIN and theconsole.D. To let readers know why his ideas are new.23.What is the writer most likely to be according to the passage?A. A famous doctor.B. An IT expert.C. An idealistD.An experienced teacher.BIf you want to be a volunteer, you have to answer the following typical questions. Do you want to work with people, animals or machines? Do you want to work indoors or outdoors, directly serve people in need or serve people behind the scenes? Every year, thousands of people in the west offer volunteer service. V olunteering greatly strengthens the community because it helps the old, the young, the weak, the sick, and the disabled and the injured to solve problems.V olunteers usually help in many different ways. They may give people advice, offer friendship to the young, drive the elderly to church (if up to the driving age), advise kids against drugs, work as assistants in schools or nursing homes, raise funds, plant trees, help out in local libraries and do many other things. V olunteering can be a few hours a week or a few hours a month. Anybody who wants to serve people in need can become a volunteer.In fact, the art of volunteering is a process of both giving and receiving. V olunteering allows volunteers to meet new people, make new friends and mix with people from all walks of life. V olunteering is an excellent way to experiment and try out new techniques and skills, discover your individual talents and explore career choice. Being a volunteer will take you on a wonderful journey and help you learn more than what you can get from books.24. As a volunteer, only when you grow old enough can you _______.A. plant trees on hillsB. drive the elderly to churchC. give advice to othersD. help out in local libraries25. How is the second paragraph mainly developed?A. By listing examples.B. By comparing.C. By giving explanations.D. By discussing.26. It can be inferred from the passage that to be a volunteer, _______.A. you can do experimentsB. you must be very strongC. you need to work very longD. you can get something valuable27. What’s the best title of the passage?A. How to Hunt for JobsB. V olunteer Service in the WestC. How to Make FriendsD. How to Work with AnimalsCThomas Edison was one of ten said to be the greatest genius of his age. There are only a few men in all of the history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a geni us. “There is no such thing as genius,” Edison said. He said that what people called genius was mostly hard work.But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to learn what could usefully be done with them.Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure.Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someoneasked him what ideas he had about life. “Work,” he answered. “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.28.

(0,1) 16. 2三、解答题17. 解 设等差数列{a n }的公差为d . 因为a 3+a 7=a 4+a 6=-4,a 3a 7=-12,所以a 3,a 7是方程x 2+4x -12=0的两根.因为d >0,所以a 3<a 7.解方程,得Error!由a 7=a 3+4d ,得d =2. 所以an =a 3+(n -3)d =-6+2(n -3)=2n -12.18. (1)解 f ′(x )=1+2ax +. 解得Error!b x (2)证明 因为f (x )的定义域为(0,+∞),由(1)知f (x )=x -x 2+3ln x . 设g (x )=f (x )-(2x -2)=2-x -x 2+3ln x ,则g ′(x )=-1-2x +=-.3x x -1 2x +3 x 当0<x <1时,g ′(x )>0,当x >1时,g ′(x )<0.所以g (x )在(0,1)上是增加的,在(1,+∞)上是减少的.而g (1)=0,故当x >0时,g (x )≤0,即f (x )≤2x -2.19. (1)证明:∵a n +S n =n , ① ∴a n +1+S n +1=n +1. ② ②-①得a n +1-a n +a n +1=1,∴2a n +1=a n +1,∴2(a n +1-1)=a n -1,∴=,∴{a n -1}是等比数列.首项c 1=a 1-1,又a 1+a 1=1, a n +1-1a n -112∴a 1=,∴c 1=-,公比q =. 又c n =a n -1,121212∴{c n }是以-为首项,公比为的等比数列.1212(2)由(1)可知c n =·n -1=-n, ∴a n =c n +1=1-n .(-12)(12)(12)(12)20. 解 (1)设等差数列{a n }的首项为a 1,公差为d .因为a 3=7,a 5+a 7=26,所以Error! 解得Error!所以a n =3+2(n -1)=2n +1, S n =3n +×2=n 2+2n .n n -1 2(2)由(1)知a n =2n +1,所以b n ===·=·, 1a 2n -11 2n +1 2-1141n n +1 14(1n -1n +1)所以T n =·(1-+-+…+-)=·(1-)=,141212131n 1n +1141n +1n4 n +1 即数列{b n }的前n 项和T n =.n4 n +1 21. 解析: (1)f ′(x )=x 2-2ax +a 2-1, ∵x =1是f (x )的极值点,∴f ′(1)=0,即a 2-2a =0,解得a =0或2.(2)∵(1,f (1))在x +y -3=0上.∴f (1)=2,∵(1,2)在y =f (x )的图像上,∴2=-a +a 2-1+b ,13又f ′(1)=-1,∴1-2a +a 2-1=-1, ∴a 2-2a +1=0,解得a =1,b =,83∴f (x )=x 3-x 2+,f ′(x )=x 2-2x ,1383由f ′(x )=0可知x =0和x =2是f (x )的极值点.∵f (0)=,f (2)=,f (-2)=-4,f (4)=8,8343∴f (x )在区间[-2,4]上的最大值为8.22. 解:(1)∵f ′(x )=-1, 令f ′(x )=0,得x 2=1-ln x .1-ln xx 2显然x =1是上面方程的解.令g (x )=x 2+ln x -1,x ∈(0,+∞), 则g ′(x )=2x +>0,1x ∴函数g (x )在(0,+∞)上单调递增. ∴x =1是方程f ′(x )=0的唯一解. ∵当0<x <1时,f ′(x )=-1>0; 当x >1时,f ′(x )<0.1-ln xx 2∴函数f (x )在(0,1)上单调递增,在(1,+∞)上单调递减.(2)由(1)知函数f (x )在(0,1)上单调递增,在(1,+∞)上单调递减. 故①当0<2m ≤1,即0<m ≤时,f (x )在[m,2m ]上单调递增.12∴f (x )max =f (2m )=-2m .ln 2m2m ②当m ≥1时,f (x )在[m,2m ]上单调递减,∴f (x )max =f (m )=-m . ③当m <1<2m ,即<m <1时,f (x )max =f (1)=-1.lnm m 12。

But the only thing that wasn’t very fun about it was that he could catch many fish while I couldn’t catch anything. I usually got pretty upset and kept asking him why. He always answered, “Son, if you want to catch a fish, you have to think like a fish”, I remember being even more upset then because, “I’m not a fish!” I didn’t know how to think like a fish. Besides, I reasoned, how could what I think influence what a fish does?As I got a little older I began to understand what my dad really meant. So, I read some books on fish. And I even joined the local fishing club and started attending the monthly meetings. I learned that a fish is a cold-blooded animal and therefore is very sensitive to water temperature. That is why fish prefer shallow water to deep water because the former is warmer. Besides, water is usually warmer in direct sunlight than in the shade. Yet, fish don’t have any eyelids(眼皮) and the sun huts their eyes… The more I understood fish, the more I became effective at finding and catching them..When I grew up and entered the business world, I remember hearing my first boss say, “We all need to think like salespeople.” But it didn’t completely make sense. My dad never once said, “If you want to catch a fish you need to think like a fisherman.” What he said was, “You need to think like a fish.” Years later, with great efforts to promote long-term services to people much older and richer than me, I gradually learned what we all need is to think more like customers. It is not an easy job. I will show you how in the following chapters.24. Why was the author upset in fishing trips when he was nine?A. He could not catch a fish.B. His father was not patient with him.C. His father did not teach him fishing.D. He could not influence a fish as his father did.25. What did the author’s father really mean?A. To read about fish.B. To learn fishing by oneself.C. To understand what fish think.D. To study fishing in many ways.26. According to the author, fish are most likely to be found _________.A. in deep water on sunny daysB. in deep water on cloudy daysC. in shallow water under sunlightD. in shallow water under waterside trees.27. After entering the business world, the author found _________.A. it easy to think like a customerB. his father’s fishing advice inspiringC. his first boss’s sales ideas reasonableD. it difficult to sell services to poor people28. This passage most likely comes from _________.A. a fishing guideB. a popular sales bookC. a novel on childhoodD. a millionaire’s biographyCNight after night, she came to pull the covers up around me and make me feel comfortable in bed, even long after my childhood years. Following her longstanding custom, she would lean down and push my long hair out of the way, then kiss my forehead.I don’t remember when it first started annoying me — her hands pushing my hair that way. But it did annoy me, for they felt work-worn and rough against my young skin. Finally, one night, I shouted out at her, “Don’t do that anymore —your hands are too rough!” She didn’t sayanything in reply. But never again did my mother close out my day with that familiar expression of her love.Time after time, with the passing years, my thoughts returned to that night. By then I missed my mother’s hands, missed her goodnight kiss on my forehead. Sometimes the incident seemed very close, sometimes far away. But always it remained in the back of my mind.Well, the years have passed, and I’m not a little girl anymore. Mom is in her mid-seventies, and those hands I once thought to be so rough are still doing things for me and my family. She’s been our doctor, reaching into a first aid kit for the remedy to calm a young girl’s stomach or soothe the boy’s injured knee. She cooks the best fried chicken in the world... gets stains out of blue jeans like I never could...Now, my own children are grown and gone. Mom no longer has Dad, and on special occasions, I find myself drawn next door to spend the night with her. So it was late on Thanksgiving Eve, as I slept in the bedroom of my youth, a familiar hand hesitantly ran across my face to brush the hair from my forehead. Then a kiss, ever so gently, touched my brow.In my memory, for the thousandth time, I recalled the night my young voice complained, “Don’t do that anymore —your hands are too rough!” Catching Mom’s hand in hand, I blurted out how sorry I was for that night. I thought she’d remember, as I did. But Mom didn’t know what I was talking about. She had forgotten — and forgiven — long ago.That night, I fell asleep with a new appreciation for my gentle mother and her caring hands. And the guilt that I had carried around for so long was nowhere to be found.29.

Without it we wouldn’t have been able to put a man on the moon, explore the ocean’s depths or eat microwave sausages(香肠). Computers have revolutionized our lives and they have the power to educate and pass on knowledge. But sometimes this power can create more problems than it solves.Every doctor has had to try their best to calm down patients who’ve come into their surgery waving an Internet print-out, convinced that they have some rare incurable disease, say, throat can cer. The truth is usually far more ordinary, though: they don’t have throat cancer, and it’s just that their throats are swollen. Being a graduate of the Internet “school” of medicine does not guarantee accurate self-health-checks.One day Mrs. Almond came to my hospital after feeling uncomfortable at work. While I took her blood sample (样本)and tried to find out what was wrong, she said calmly, “I know what’s wrong; I’ve got throat cancer. I know there’s nothing you doctors can do about it and I’ve just got to wait until the day comes.”As a matter of routine I ordered a chest X-ray. I looked at it and the blood results an hour later. Something wasn’t right.“Did your local doctor do an X-ray?” I asked. “Oh, I haven’t been to the doctor for years,” she replied. “I read about it on a website and the symptoms fitted, so I knew that’s what I had.”However, some of her symptoms, like the severe cough and weight loss, didn’t fit with it—but she’d just ignored this.I looked at the X-ray again, and more tests confi rmed it wasn’t the cancer but tuberculosis (肺结核)—something that most certainly did need treating, and could be deadly. She was lucky we caught it when we did.Mrs. Almond went pale when I explained she would have to be on treatment for the next six months to ensure that she was fully recovered. It was certainly a lesson for her. “I’m so embarrassed,” she said, shaking her head, as I explained that all the people she had come into close contact with would have to be found out and tested. She listed up to about 20, and then I went to my office to type up my notes. Unexpectedly, the computer was not working, so I had to wait until someone from the IT department came to fix it. Typical. Maybe I should have a microwave sausage while I waited?33.
