可岩羊“纹丝不动” 事实与心理预期出现了落差能够引发读者的预测激发读者的好奇心从人物心理状态来看岩羊“纹丝不动” 他步步靠近时经历了一个先“引起了他足够的好奇” 再“有些迟疑”“他的心有点缩紧——太奇怪了!真是匪夷所思!” 接着“惊呆了” 知道岩羊不动的原因“心疼极了”“心情很沉重” 最后“下山的时候他的心情多少有些缓了过来”的心理历程和情感变化过程从主旨来看他步步靠近机敏的岩羊却不动是因为岩羊已经老态垂死这引发了人们对于生命的思考揭示了文章的主旨综合以上分析整理作答即可【答案】(4)①“他”割下这只老岩羊的首级体现了“他”对老岩羊的充分尊重对生命尊严的尊重②从文中“心疼”“不忍心”“祈祷”“将老岩羊头面朝东方”等细节可知“他”对老岩羊这种垂垂老矣、艰难等死的状态心生悲悯之情③从后面“彻悟”可知从老岩羊的垂老艰难活着到肉体回归自然引发对生命的感悟生命是一个过程最终会走向尽头但即使走向尽头也要有尊严从而深化了热爱生命、关爱生命、尊重生命的主题【解析】(4)回答本题要结合上下文内容及思想主旨进行分析面对“已经痴呆的老岩羊它根本意识不到人的走近双眼蒙满了眵目糊牙也掉尽那一对毡房穹顶般的犄角尖已经深深地长进后臀皮肉里了”时他心疼极了而后又想“难道没有哪只狼来成全你么”“生命总该有个尽头” 在这样的想法之下他才割了老岩羊的首级并“将长进后臀皮肉里的犄角尖拔出面朝东方搁置好羊头依然保持着它曾经的尊严” 由此可见他割下老岩羊的首级是因为极度心疼他悲悯老岩羊的遭遇想让它有尊严地死去他的做法是对生命的尊重割下老岩羊的首级后“他看见天空中开始有秃鹫盘旋还有几只乌鸦和喜鹊捷足先登落在大圆石上开始争食老岩羊的肉” 如果不是他割下老岩羊的首级老岩羊会在其他动物的嘴下毫无尊严地死去他从眼前的景象和自己的行为中有了新的思考无论多么强大的生命最终都会走向死亡回归到自然当中去这就是生命的过程可即便是死亡也应该有尊严所以他的这一行为深化了热爱生命、关爱生命、尊重生命的主题综合以上分析整理作答即可8.(1)下列对材料相关内容的理解和分析不正确的一项是()8.(2)下列对材料相关内容的概括和分析不正确的一项是()8.(3)我国应该如何更好地发挥中医药的价值?请结合材料概括说明A.

【解析】此题主要考查导数的几何意义及三角形面积公式,属于基础题,先求出曲线f(x)=e x lnx 在x =1处的切线方程,再其求与坐标轴的交点即可求得三角形面积;解:f ′(x)=e xlnx +e x x,则f ′(1)=e ,f(1)=0,∴曲线f(x)=e x lnx 在x =1处的切线方程为y =e(x −1),令x=0,得y=−e,令y=0,得x=1,∴切线与坐标轴围成的三角形面积为S=12×e×1=e2.故选B.8.【答案】B;【解析】解:函数的导数为f′(x)=2x+3,所以函数在A(1,4)处的切线斜率k=f′(1)=2+3=5.故选:B.求曲线在点处得切线的斜率,就是求曲线在该点处得导数值.该题考查了导数的几何意义.导数的几何意义是指函数y=f(x)在点x0处的导数是曲线y= f(x)在点P(x0,y0)处的切线的斜率.它把函数的导数与曲线的切线联系在一起,使导数成为函数知识与解析几何知识交汇的一个重要载体.9.【答案】BCD;【解析】此题主要考查极值的概念,导数的几何意义,利用导数研究函数的单调性,利用单调性求解不等式,属于中档题.由题意结合知识点,逐个选项分析即可.解:选项A,若f′(x0)=0,x0不一定是函数f(x)的极值点,例如函数f(x)=x3,f′(0)=0,但x=0不是极值点,故错误;选项B,函数y=f(x)的切线与函数可以有两个公共点,例如函数f(x)=x3−3x,在x=1处的切线为y=−2与函数还有一个公共点为(−2,−2),故正确;选项C,因为函数y=f(x)在x=1处的切线方程为2x−y=0,所以f′(1)=2,故正确. 选项D,令g(x)=f(x)−x−1,因为函数f(x)的导数f′(x)<1,则g′(x)=f′(x)−1<0,所以函数g(x)=f(x)−x−1在R上单调递减,又g(1)=f(1)−2=0,由不等式f(x) > x+1得g(x) > 0=g(1),得x 1,所以不等式f(x) > x+1的解集是(−∞,1),故正确.故选BCD.10.【答案】AB;【解析】解:由题意,可知若函数y =f(x)具有“T 性质”,则存在两点, 使得函数在这两点处的导数值的乘积为−1, 对于A ,(xe x )′=1−x e x,满足条件;对于B ,(cosx +1)′=−sinx ,满足条件;对于C ,(1x 3)′=−3x 4<0恒成立,负数乘以负数不可能得到−1,不满足条件;对于D ,(ln2log 2x)′=ln2.1xln2=1x >0恒成立,正数乘以正数不可能得到−1,不满足条件. 故选:AB.分别求出四个选项中函数的导函数,看是否满足存在两点,使得函数在这两点处的导数值的乘积为−1即可.此题主要考查导数的几何意义及应用,考查化归与转化思想,关键是熟记基本初等函数的导函数,是中档题.11.【答案】ABD; 【解析】此题主要考查导数的运算和几何意义以及基本不等式求最值,属于中档题. 由题意和导数的运算结合基本不等式,逐个选项验证正误即可. 解:已知f(x)=x +√2x,当x >0时,f(x)=x +√2x⩾2√24,当x <0时,f(x)=x +√2x⩽−2√24,故选项A 、B 不正确;设直线l 与函数f(x)的图象相切于点(x 0,x 02+√2x 0),函数f(x)的导函数为f ′(x)=1−√2x 2=x 2−√2x 2,则直线l 的方程为y −x 02+√2x 0=x 02−√2x 02(x −x 0),即y =x 02−√2x 02x +2√2x 0,直线l 与g(x)=x 的交点为M(2x 0,2x 0),与x =0的交点为N(0,2√2x 0), 所以|MN|2=4x 02+(2x 0−2√2x 0)2=8x 02+8x 02−8√2⩾16−8√2,当且仅当x 02=1时取等号,故选项C 正确; f ′(x)=1−√2x 2=x 2−√2x 2⩽1,可知切线斜率可为负值,即倾斜角可以为钝角,故选项D 不正确.故选ABD.12.【答案】AC;【解析】此题主要考查导数的几何意义和二次方程的实根的分布,考查运算能力,属于中档题.求出导数,由题意可得2x2−2x+a=3有两个不相等的正根,由此列出不等式组即可得到a 的取值范围,进而可得a的可能取值.解:f(x)=23x3−x2+ax−1的导数为f′(x)=2x2−2x+a,由题意可得2x2−2x+a=3有两个不相等的正根,则{Δ=28−8a>0a−32>0,解得3<a<72,故选:AC.13.【答案】BCD;【解析】解:函数f(x)=x−ln|x|x的定义域为{ x|x≠0},f(−x)+f(x)=1−ln|−x|−x +1−ln|x|x=2≠0,所以f(x)不为奇函数,故A错误;由f(x)=1,可得ln|x|x=0,解得x=±1,故y=f(x)−1有两个零点,故B正确;由f(−x)+f(−2x)+f(x)+f(2x)=[f(−x)+f(x)]+[f(−2x)+f(2x)]=2+2=4,则函数y=f(x)+f(2x)的图象关于点(0,2)对称,故C正确;当x>0时,f(x)=1−lnxx ,f′(x)=−1−lnxx2,设过原点与f(x)相切的切点为(m,n),则切线的方程为y−n=lnm−1m2(x−m),即y−1+lnmm =lnm−1m2(x−m),代入(0,0),可得1+m=2lnm,设g(m)=2lnm−1−m,g′(m)=2m−1,当0<m<2时,g(m)递增,m>2时,g(m)递减,则g(m)的最大值为g(2)=2ln2−3<0,所以x>0时,不存在过原点的切线;当x<0时,f(x)=1−ln(−x)x ,f′(x)=−1−ln(−x)x2,设过原点与f(x)相切的切点为(s,t)(s<0),则切线的方程为y−t=ln(−s)−1s2(x−s),即y−1+ln(−s)s =ln(−s)−1s2(x−s),代入(0,0),可得1+s=2ln(−s),设g(s)=2ln(−s)−1−s,g′(m)=2s−1<0,所以g(s)递减,则g(s)只有一个零点,所以x<0时,只存在一条过原点的切线.综上可得存在一条过原点的切线,故D正确.故选:BCD.由函数的奇偶性和零点、对称性、导数的几何意义,可得结论.此题主要考查导数的运用:求切线的方程,考查方程思想和运算能力、推理能力,属于中档题.14.【答案】x−y+ln2−2=0;【解析】由直线的倾斜角求得直线的斜率,求出原函数的导函数,由导函数值为1求解切点坐标,再由直线方程的点斜式得答案.此题主要考查利用导数研究过曲线上某点处的切线方程,熟记基本初等函数的导函数是关键,是基础题.解:直线的倾斜角为45°,则直线的斜率为tan45°=1,由y=lnx−2x +1,得y′=1x+2x2,由y′=1x +2x2=1,解得x=−1(舍去)或x=2.∴切点坐标为(2,ln2),则直线l的方程为y−ln2=1×(x−2),即x−y+ln2−2=0.故答案为:x−y+ln2−2=0.15.【答案】y=−x或y=−14x或y=2x;【解析】求出函数的导数,结合直线关系即可得到结论.这道题主要考查函数的切线的求解,根据函数导数的几何意义是解决本题的关键.注意要进行分类讨论.解:函数的导数为f ′(x)=3x 2−6x +2, 设切点为(a,b),则k =f ′(a)=3a 2−6a +2,b =a 3−3a 2+2a , 则切线的方程y −b =(3a 2−6a +2)(x −a), 即y =(3a 2−6a +2)x −2a 3+9a 2−4a , ∵直线l 过点(0,0), ∴−2a 3+9a 2−4a =0, 即2a 3−9a 2+4a =0, 则a(a −4)(2a −1)=0, 解得a =0或a =4或a =12,当a =1时,对应的直线方程为y =−x , 当a =12时,对应的直线方程为y =−14x , 当a =0时,对应的直线方程为y =2x , 故答案为:y =−x 或y =−14x 或y =2x16.【答案】(0,4-2√3) ; 【解析】此题主要考查函数的零点与方程的根之间的关系,函数的导数求解切线方程,考查数形结合以及计算能力,是难题.画f(x)={1−2x ,x ⩾012x 2+2x,x <0,的图象,结合直线g(x)=k(x −2)过定点(2,0),函数g(x)的图象与f(x)=12x 2+2x ,x <0的图象相切时,函数f(x),g(x)的图象恰有两个交点.设切点为P(x 0,y 0),由f ˈ(x)=x +2,x <0,求出切线的斜率,利用函数的图象的交点个数与函数的零点个数,推出k 的范围即可.解:依题意,画出f(x)={1−2x,x⩾012x2+2x,x<0的图象如图:因为直线g(x)=k(x−2)过定点(2,0),由图象可知,当函数g(x)的图象与f(x)=12x2+2x,x<0的图象相切时,函数f(x),g(x)的图象恰有两个交点.下面利用导数法求该切线的斜率.设切点为P(x0,y0),由fˈ(x)=x+2,x<0,则k=f′(x0)=x0+2=12x02+2x0x0-2,解得x0=2+2√3(舍去)或x0=2-2√3,则k=4−2√3,要使方程f(x)=g(x)恰有三个实数解,则函数f(x),g(x)的图象恰有三个交点,结合图象可的实数k的取值范围为(0,4-2√3),故答案为(0,4-2√3).17.【答案】23;【解析】解:由f(x)=√4x+1,得f′(x)=2(4x+1)−1 2,所以函数f(x)在x=2处切线的斜率k=f′(2)=23.故答案为:23.对f(x)求导,根据导数的几何意义,得到f(x)在x=2处的切线斜率.此题主要考查了利用导数研究函数的切线方程和导数的几何意义,属基础题.18.【答案】32;【解析】解:S=t+2√t,∴S′=1+√t,∴它在4秒末的瞬时速度为1+√4=32,故答案为:32.物理中的瞬时速度常用导数来求,故求出S的导数,代入4求值.该题考查变化的快慢与变化率,解答本题关键是理解导数的物理意义,由此转化为求导数的问题.19.【答案】解:(1)∵f′(x)=(x3+x−16)′=3x2+1,∴在点(2,−6)处的切线的斜率k=f′(2)=3×22+1=13,∴切线的方程为y=13x−32.(2)设切点为(x0,y0),则直线l的斜率为f′(x0)=3x02+1,∴直线l的方程为y=(3x02+1)(x−x0)+x03+x0−16.又∵直线l过点(0,0),∴0=(3x02+1)(−x0)+x03+x0−16,整理,得x03=−8,∴x0=−2,∴y0=(−2)3+(−2)−16=−26,直线l的斜率k=3×(−2)2+1=13,∴直线l的方程为y=13x,切点坐标为(−2,−26).;【解析】(1)先求出函数的导函数,再求出函数在(2,−6)处的导数即斜率,易求切线方程.(2)设切点为(x0,y0),则直线l的斜率为f′(x0)=3x02+1,从而求得直线l的方程,有条件直线1过原点可求解切点坐标,进而可得直线1的方程.此题主要考查直线的点斜式方程,属基础题型,较为简单.20.【答案】解:(1)由y=ax2(a>0)得y′=2ax(a>0),则曲线在点A处的切线斜率为2am1,曲线在点A处的切线方程为y−am12=2am1(x−m1),曲线在点A处的切线过点P(1,−3),故am12−2am1−3=0①,同理可得曲线y=ax2(a>0)在点B处的切线方程为y−am22=2am2(x−m2),∴am12−2am1−3=0②,①−②得m1+m2=2,m2−m1=4,∵m2−m1=4,∴m1=−1,m2=3,将m1=−1代入①,可得a=1,故抛物线方程为x2=y;(2)由题意知直线l的斜率存在,设直线l的方程为y=kx+b,与抛物线C的交点为M(x1,x12),N(x2,x22),联立得{y=kx+bx2=y,得x2−kx−b=0,∴x1+x2=k,x1.x2=−b,∴k OM.k ON=x12x1.x22x2=x1x2=−2,可得b=2,∴直线l经过点(0,2),∴SΔ=12×|OP|×|x1−x2|=2√3,∴|x1−x2|=2√3,∴k2=4,∴k=±2,经检验k=±2,b=2符合题意,∴直线l的方程为y=2x+2或y=2x−2.;【解析】此题主要考查了直线与抛物线涉及到利用导数求曲线的切线方程、抛物线的几何性质、直线方程的求法等知识,综合性较强.(1)利用导数,可以求出曲线在点A,B处的切线斜率为2am1,2am2,从而求出切线方程,得到关于m1,m2的关系式,可以求出m的值,从而求出切线方程;(2)设直线l的方程为y=kx+b,与抛物线C的交点为M(x1,x12),N(x2,x22),联立得{y=kx+bx2=y,得x1+x2=k,x1.x2=−b,求出b=2,根据题意列方程求出k的值,从而求出直线方程.21.【答案】(本题满分为12分)解:(1)f′(x)=lnx+ax+1,由题意知,曲线y=f(x)在点(1,f(1))处的切线斜率为2,则f'(1)=2,所以a+1=2,解得a=1.…(4分)(2)令ˈ(x)=f(x)−g(x)=(x+1)lnx−x 2e x,x∈(1,2),则ˈ(1)=−1e <0,ˈ(2)=3ln2−4e2>0,所以h(1)h(2)<0,所以函数h(x)在(1,2)内一定有零点,…(8分)可得ˈ′(x)=lnx+x+1x −2x−x2e x(e x)2=lnx+1x+1−−(x−1)2+1e x>1−1e>0,∴h(x)在(1,2)上单调递增,所以函数h(x)在(1,2)内有且只有一个零点,即方程f(x)=g(x)在(1,2)内有且只有一个实根.…(12分);【解析】(1)求得f(x)的导数,可得x=1处切线的斜率,由两直线平行的条件:斜率相等,解方程即可得到所求值.(2)令ˈ(x)=f(x)−g(x)=(x+1)lnx−x2e x ,x∈(1,2),由ˈ(1)=−1e<0,ˈ(2)=3ln2−4e2>0,可得函数ˈ(x)在(1,2)内一定有零点,进而证明ˈ′(x)>0,可得ˈ(x)在(1,2)上单调递增,即可得证.此题主要考查导数的运用:求切线的斜率,考查两直线平行的条件:斜率相等,考查函数的零点判定定理,正确求导是解答该题的关键,属于中档题.22.【答案】解:(I )由题意得,f(x)=ae x +1aex+b ,则f ′(x)=ae x −1ae x,因为在点(2,f (2))的切线方程为y=32x ,所以{(f(2)=3f ′(2)=32), 即{(ae 2+1ae 2+b =3ae 2−1ae 2=32),解得{(a =2e 2b =12)…(6分)(Ⅱ)设t=e x (t ≥1),则原函数化为:y =at +1at +b , 所以y ′=a −1at 2=a 2t 2−1at 2,令y ′=0,解得t=±1a ,(1)当a ≥1时,则y ′>0在[1,+∞)上成立, 所以函数y =at +1at +b 在[1,+∞)上是增函数, 则当t=1(x=0)时,函数f (x )取到最小值是a +1a +b ; (2)当0<a <1时,y =at +1at +b ≥2+b ,当且仅当at=1(t=e x =1a >1,则x=-lna )时,取等号, 此时函数f (x )取到最小值是b+2,综上可得,当a ≥1时,函数f (x )的最小值是a +1a +b ; 当0<a <1时,函数f (x )的最小值是b+2.…(12分); 【解析】(Ⅰ)由求导公式和法则求出f ′(x),根据导数的几何意义和条件列出方程组,求出a 、b 的值;
