x,则b=cos x,0<x<,则a+b=sin x+cos x=sin(x),∵0<x<,∴<x<,即当x=时,a+b取得最大值为,法2:设z=a+b,则b=﹣a+z,平移直线b=﹣a+z,由图象知当直线与图象在第一象限相切时,直线的截距最大,此时z最大,圆心到直线的距离d==1,得|z|=,则z=或z=﹣(舍),故a+b取得最大值为,故选:D.9.(5分)函数y=x3﹣2ax+a在(1,2)内有极小值,则实数a的取值范围是()A.(0,)B.(0,3)C.(,6)D.(0,6)【解答】解:对于函数y=x3﹣2ax+a,求导可得y′=3x2﹣2a,∵函数y=x3﹣2ax+a在(1,2)内有极小值,∴y′=3x2﹣2a=0,则其有一根在(1,2)内,a>0时,3x2﹣2a=0两根为±,若有一根在(1,2)内,则1<<2,即<a<6,a=0时,3x2﹣2a=0两根相等,均为0,f(x)在(1,2)内无极小值,a<0时,3x2﹣2a=0无根,f(x)在(1,2)内无极小值,综合可得,<a<6,故选:C.10.(5分)观察(x3)′=3x2,(x5)′=5x4,(sin x)′=cos x,由归纳推理得:若定义在R上的函数f(x)满足f(﹣x)=﹣f(x),记g(x)为f(x)的导函数,则g(﹣x)=()A.f(x)B.﹣f(x)C.g(x)D.﹣g(x)【解答】解:根据(x3)′=3x2、(x5)′=5x4、(sin x)′=cos x,发现原函数都是一个奇函数,它们的导数都是偶函数由此可得规律:一个奇函数的导数是偶函数.而定义在R上的函数f(x)满足f(﹣x)=﹣f(x),说明函数f(x)是一个奇函数因此,它的导数应该是一个偶函数,即g(﹣x)=g(x)故选:C.11.(5分)已知函数f(x)(x∈R)满足f(1)=1,且f(x)的导函数f′(x)≥,则f(x)<+的解集为()A.{x|x<1}B.{x|x>1}C.{x|x<﹣1}D.{x|x>﹣1}【解答】解:设g(x)=f(x)﹣﹣,则g'(x)=f'(x)﹣,∵f(x)的导函数f′(x)≥,∴g'(x))=f'(x)﹣0,即函数g(x)在定义域上单调递增,∵g(1)=f(1)﹣=0,∴当x<1时,g(x)<g(1)=0,∴不等式f(x)<+的解集为(﹣∞,1),故选:A.12.(5分)函数f(x)的导函数为f′(x),对任意的x∈R都有3f′(x)>f(x)成立,则()A.3f(3ln2)>2f(3ln3)B.3f(3ln2)与2f(3ln3)的大小不确定C.3f(3ln2)=2f(3ln3)D.3f(3ln2)<2f(3ln3)【解答】解:令h(x)=,则h′(x)=,因为对任意的x∈R都有3f′(x)>f(x)成立,所以3f′(3lnx)>f(3lnx),所以h′(x)>0,h(x)在(0,+∞)上单调递增,所以h(2)<h(3),即<,所以3f(3ln2)<2f(3ln3).故选:D.二、填空题(每题5分共20分)13.(5分)在凸多边形当中显然有F+V﹣E=1(其中F:面数,V:顶点数,E:边数)类比到空间凸多面体中有相应的结论为;F+V﹣E=2.【解答】解:根据凸多边形当中有:F+V﹣E=1,其中F:面数,V:顶点数,E:边数;类比到空间凸多面体中有相应的结论为;F+V﹣E=2;如四面体的顶点数V=4,面数F=4,边数E=6,则V+F﹣E=4+4﹣6=2.故答案为;F+V﹣E=2.14.(5分)若f(2)=3,f′(2)=﹣3,则=9.【解答】解:由洛必达法则可知:==3﹣2×f′(2)=9,故答案为:9.15.(5分)设f(x)是定义在R上的奇函数,当x>0时,f′(x)sin x+f(x)cos x>0且f()=1,则f(x)sin x≤1的整数解的集合为{﹣1,0,1}.【解答】解:设g(x)=f(x)sin x,则g′(x)=f′(x)sin x+f(x)cos x,∵当x>0时,f′(x)sin x+f(x)cos x>0∴当x>0时,g′(x)>0,∴当x>0时,g(x)单调递增,∵f(x)是定义在R上的奇函数,∴g(x)是偶函数,∵f()=1,∴g()=1,∵f(x)sin x≤1,∴|x|≤,∴f(x)sin x≤1的整数解的集合为{﹣1,0,1}.故答案为:{﹣1,0,1}.16.(5分)若(x2+)dx=+ln3,则a的值是3.【解答】解:(x2+)dx=(+lnx)|=a3+lna﹣﹣ln1=+ln3,∴a=3,故答案为:3.三、解答题(17题10分其它每题12分共70分)17.(10分)求下列函数的积分.(1)(x2+)dx;(2)dx.【解答】解:(1)(x2+)dx=(x3+)|=+=1,(2)dx表示以原点为圆心以2为半径的圆的面积的四分之一,故dx=π18.(12分)已知数列{a n}中a1=3,a n=.(1)求出a2,a3,a4的值;(2)利用(1)的结论归纳出它的通项公式,并用数学归纳法证明.【解答】解:(1)a2=,a3=,a4=,(2)猜测:a n=证明如下:1.当n=1时显然成立,2.设n=k时成立即a k=,则当n=k+1时有a k+1====,所以成立由1,2可知n∈一切自然数均成立,所以猜测正确.19.(12分)设函数f(x)=,M={x|f(x)<0},P={x|f′(x)>0},若M⊂P,则实数a的取值范围.【解答】解:a>1时,M={﹣a<x<﹣1};a<1时M={x|﹣1<x<﹣a};a=1时M=∅;;∴a<1时f′(x)>0恒成立,a≥1时f′(x)>0的解为空集;∵M⊂P;∴a的范围是(﹣∞,1).20.(12分)f(x)=lnx﹣ax+1.(1)求f(x)的单调增区间.(2)求出f(x)的极值.【解答】解:(1)f′(x)=﹣a(x>0)∴当a≤0时f′(x)>0恒成立,∴f(x)的增区间为(0,+∞),当a>0时,f′(x)>0的解为(0,),∴f(x)的增区间为(0,);(2)f′(x)=﹣a=0解得:x=,∴a>0时,x∈(,+∞)时,f′(x)<0,x∈(0,)时,f′(x)>0,∴x=是f(x)的极大值无极小值,当a≤0时,f′(x)>0恒成立,无极值.21.(12分)已知函数f(x)=x3﹣ax2﹣3x.(1)若a=4时,求f(x)在x∈[1,4]上的最大值和最小值;(2)若f(x)在x∈[2,+∞]上是增函数,求实数a的取值范围.【解答】解:(1)a=4时,f(x)=x3﹣4x2﹣3x,∴f′(x)=3x2﹣8x﹣3,∴函数在[1,3]上单调递减,[3,4]上单调递增,∴f(x)在x∈[1,4]上的最大值为f(1)=﹣6,最小值为f(3)=﹣18;(2)在x∈[2,+∞]上,f′(x)=3x2﹣2ax﹣3≥0,可得a≤在x∈[2,+∞]上恒成立,∴只要求的最小值即可,而y=.y′=恒大于零,∴y在R上为增函数,∴y min=,∴a≤.22.(12分)求由三条曲线:y=x2,y=x2,y=2 所围成的图形的面积.【解答】解:由三条曲线:y=x2,y=x2,y=2 所围成的图形的面积如图所示:故其面积S=2(﹣)dy=2(﹣1)dy=2(﹣1)•|=.。

Aplaying basketball is an easy way for teens to have fun while buring a few calories.I usually get bored of sitting on the sofa all day playing video games or watching television. You can play alone. But Playing with teammates is more attractive for me. Besides, when I possess the ball I have the feeling of being the best and no onecould stop me.I also believe out of all these sports basketball is the best sport to watch on television. When wacthing it, I can take the moves I see the professional perform and add them to my style of play. I take many of my moves from professional basketball players and make them my own. There are a variety of tricks the players perform during games, which make the games much more enjoyable to watch.My favorite player is Kobe Bryant. He is an all-round athlete and is still going strong at 30 years old. He is a big role model to many kids who enjoy playing this sport. He knows how to play both sides of the game offense and defense. I want to play like him as I continue to get better and better every time I play basketball. Basketball is a great way to get your mind off things and is also a great wayto express yourself. It is a sport that can exercise your whole body. I want to play more and more of it.实用文档21.

That is why most people around the world love music. Music is so good that they just can't live without it. They listen to music as soon as they get up in the morning,and sleep only if they listen to music. So ,take a look at the signs below to know whether you're a true music lover or not.You and your earphones are inseparable(形影不离的).You're always seen with your earphones on. Once you take your earphones away from your ears, you will feel very bored, so you decide to put them back on your ears again. If you leave them at home, you will go home to get them.You sometimesforget that you're in a public place.You forget that you can't sing loudly in public places, but when you realize that, it's too late. A lot of people come to watch you. They enjoy your favorite song that you're singing at the top of your voice.Car drives and trips are impossible without music.A trip or ride without music seems like 100 hours longer for you, and you imagine how much you'd get bored! When you park your car , and your favorite song comes up, you'll wait till it ends.You make full use of your time to sing in the bathroom.I'm sure most of you out there are bathroom singers.It's like you are on thestage as soon as you enter the bathroom, which sometimes causes some accidents. You know why! You love to sing. But sadly, you aren't born with a good voice. In order to make other people not laugh at your bad voice, you sing in the bathroom.

He loves junk mails. Thanks to a mailman and the Internet, he went into the sea of books.Advertisements were the only reading materials for the boy . Flores loves reading so much that he walked to his mailman in a Salt Lake City suburb on Friday to askif he could have any junk mail.The strange question attracted the mailman, Ron Lynch, to ask why. Lynch recorded Flores' special answers on his Facebook page.“ Today I saw a boy reading ads, and then he asked me if I had any extra mail he could read,” Lynch wrote. “He told me his biggest dream is to have books to read. I told him the library and bookshops had many books for readers, but he said his family couldn't afford them.”Lynch then asked his Facebook friends if they could donate some books to Flores. Facebook friends responded quickly. Lynch thought the Facebook post might bring in 50 to 60 books. But his request went viral(病毒性的). People from around the world,including the U.K, Australia and India, have sent books. Hundreds of books have been sent or mailed to the boy's door so far, with hundreds more likely on their way,and he's amazed at the generosity(慷慨)。
