With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals! This is what you see on Valentine’s Day, a day named after Valentine who was a priest in the third century Rome. When the emperor (皇帝) decided that single men could bee better soldiers than those with wives, he didn’t allow marriage.But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor sentenced him to death. While in prison, it is said that Valentine fell in love with the daughter of his prison guard. Before his death, he wrote her a letter, which he signed “From your Valentine”, an expression that is still in use today. Valentine died for what he believed in and so he was made a Saint (圣徒), as well as being one of history’s most romantic characters.Nowadays, Valentine’s Day is also popular among Chinese young people. Some students are planning to make Valentine’s cards for parents, teachers and friends. Others want to hold parties at which they will exchange small gifts and eat heart-shaped cakes. The idea is to have fun and encourage people to share in the spirit of St. Valentine.61. Why did the emperor in Rome not allow marriage in his country?A. Because there were few women in his country at that time.B. Because he thought men without wives could be better soldiers.C. Because there wasn’t enough food for so many people.D.

The last of the three hundred gold medals has been awarded and the flags of the winners have been raised for the last time.The final event is the closing ceremony. This occasion is always sad and happy at the same time. It is a sad occasion because the tremendous excitement is over, and it will not happen again for four years. Those who have made friends will have to say goodbye, perhaps for ever. It is also a happy occasion because the petition is over and the athletes can really show their friendship for one another.The closing ceremony is rather like the opening. But now the Olympic flame goes out and the Olympic flag, with its five rings, is lowered. The person who closes the Games calls upon the youth of the world to meet again in four years’ time. The scoreboard lights up with the name of the city for the next Games and the band starts to play. Then the celebration starts.All the athletes try to be at the closing ceremony. They have forgotten all their fears and worries. It does not matter whether they have done well or not. All the teams walk round the stadium together. Everybody is laughing and joking. The band plays and people start to dance.After that, everybody in the Village clears up and gets ready to leave. Everyone is hunting for souvenirs. People exchange track suits, hats, running vests and badges. There is a last chance to take photographs and get addresses of new friends. Then each team starts its journey home.68.

There is one extra heading which you do not need.72._____________Stress es from mental or emotional activity and physical activity. It is unique and personal to each of us. You need stress in your life. Without stress, life would be dull and unexciting. Stress adds flavour, challenge, and opportunity to life. Too much stress, however, can seriously affect your physical and mental peace. A major challenge in this stress-filled world of today is to make the stress in your life work for you instead of against you.73. ____________When you are nervous, angry, or upset, release the pressure through exercise or physicalactivities. Running, walking, playing tennis, or working in your garden are just some of the activities you might try. Physical exercise will relieve that “uptight” fe eling, relax you, and turn the frowns (皱眉) into smiles. Remember, your body and your mind work together.74.____________You are special. Get enough rest and eat well. If a problem is beyond your control and cannot be changed at the moment, don’t fight the situation. If you are irritable (急躁的) and tense from lack of sleep or if you are not eating correctly, you will have less ability to deal with stressful situations. If stress repeatedly keeps you from sleeping, you need a break from your daily routine to just relax and have fun, or you should ask your doctor for help. Be good to yourself.75.____________One way to keep from getting aboard, sad, and lonely is to go where it’s all happening. Sitting alone can make you feel disappointed. Instead of feeling sorry for yourself, get involved. Offer your services in neighbourhood or volunteer organizations. Help yourself by helping other people. Get involved in the world and the people around you, and you’ll find they will be attracted to you. You will be on your way to make new friends and enjoy new activities.76.____________The best way of avoiding stress is to relax. Unfortunately, many people try to relaxat the same pace that they lead the rest of their lives. For a while, forget your worries about time, productivity, and “doing right”. You will find satisfaction in just being, without struggling hard. Find activities that give you pleasure and that are good for your mental and physical well-being. Read a good book or listen to beautiful music to create a sense of peace. Forget about always winning. Focus on relaxation, enjoyment, and health.第Ⅱ卷（24%）IV.

1＝﹣10+2k ，c k ＝c k +1+2＝﹣8．又S 2k +1＝﹣50，故2（c 1+c 2+⋯+c k ）+c k +1＝﹣50，即c 1+c 2+⋯+c k ＝﹣20， 由等差数列前n 项和公式有k(−10+2k−8)2=−20，化简得k 2﹣9k +20＝0，解得k ＝5或k ＝4． 故答案为：5或4．16．若对任意的x 1，x 2∈[1，π2]，x 1＜x 2，x 2sinx

所以A =π3，则a 2＝b 2+c 2﹣2bc cos A ＝b 2+c 2﹣bc ，由①知，a 2＝c 2+bc ，代入可得，b ＝2c ，所以a =√3c ， 即sinA =√3sinC ；选①③作条件，②当结论，由③得：a=√3c，因为a2＝c2+bc，所以3c2＝c2+bc，则b＝2c，所以cosA=b2+c2−a22bc=12，0＜A＜π，所以A=π3，由③知，sinA=√3sinC，所以sinC=sinA√3=12，所以C=π6，所以B=π2，所以，b+bcosA=2c+c=3c=√3×√3c=√3a=√3asinB；选②③作条件，①当结论，由②得：sinB+sinBcosA=√3sinAsinB，而sin B＞0，所以1+cosA=√3sinA，即√3sinA−cosA=1，根据辅助角公式可得，sin(A−π6)=12，所以，A=π3，由③，sinA=√3sinC，所以sinC=sinA3=12，得：C=π6，所以B=π2，所以sinA=√3sinC，sin B＝2sin C，则a=√3c，b＝2c，即：a2﹣c2＝bc．18．（12分）已知函数f(x)=(1x+1)ln(1+x)．（1）求曲线y＝f（x）在点（1，f（1））处的切线方程；（2）求函数f（x）的单调增区间．解：（1）因为f(x)=(1x+1)ln(1+x)，定义域为（﹣1，0）∪（0，+∞），所以f′(x)=−1x2ln(1+x)+(1x+1)11+x=x−ln(x+1)x2，又f′（1）＝1﹣ln2，f（1）＝2ln2，所以切线方程为y＝（1﹣ln2）（x﹣1）+2ln2，即y＝（1﹣ln2）x+3ln2﹣1．（2）函数f（x）定义域为（﹣1，0）∪（0，+∞），f′(x)=x−ln(x+1)x2，设g（x）＝x﹣ln（x+1），x∈（﹣1，0）∪（0，+∞），所以g′(x)=1−1x+1=xx+1，当x∈（﹣1，0）时，g′（x）＜0，函数单调递减，当x∈（0，+∞）时，g′（x）＞0，函数单调递递增，所以g （x ）min ＞g （0）＝0，所以g （x ）＝x ﹣ln （x +1）＞0恒成立， 所以f ′(x)=x−ln(x+1)x 2＞0在（﹣1，0）∪（0，+∞）上恒成立， 所以函数f （x ）在（﹣1，0）和（0，+∞）上单调递增， 所以函数f （x

=2+4(1−8n−12)1−8+16(1−8n−12)1−8=20(8n−12−1)7+2，当n ＝1时，S 1＝2，符合上式，故S n ={6(8n2−1)7，n 为偶数20(8n−12−1)7+2，n 为奇数．21．（12分）为传承和发扬淄博陶瓷，某陶瓷公司计划加大研发力度．为确定下一年度投资计划，需了解年研发资金x i （亿元）与年销售额y i （亿元）的关系．该公司对历史数据进行对比分析，建立了两个函数模型：①y ＝α+βx 2，②y ＝e λx +t ，其中α，β，λ，t 均为常数，e 为自然对数的底数．现该公司收集了近12年的年研发资金x i 和年销售额y i 的数据，i ＝1，2，⋯，12，并对这些数据作了初步处理，得到了散点图及一些统计量的值．令u i =x i 2(i =1，2，⋯，12)，v i ＝lny i （i ＝1，2，⋯，12），经计算得如下数据：（1）设{u i }和{y i }的相关系数为r 1，{x i }和{v i }的相关系数为r 2，请从相关系数的角度，选择一个拟合程度更好的模型；（2）根据（1）的选择及表中数据，建立y 关于x 的回归方程（计算过程中保留到0.001，最后结果精确到0.01）；（3）为进一步了解人们对新款式瓷器喜爱程度（分为“比较喜欢”和“不太喜欢”）是否跟年龄（分为“小于30岁”和“不小于30岁”）有关，公司从该地区随机抽取600人进行调查，调查数据如表：根据小概率α＝0.001的独立性检验，分析该地区对新款式瓷器喜爱程度是否与年龄有关． 附：①相关系数r =∑(x i −x)(y −y)ni=1√∑(x i −x)2∑ n i=1(y i −y)2i=1，回归直线y =a +bx 中斜率和截距的最小二乘估计公式分别为：b =∑x i y i −nxy ni=1∑x i 2−x2ni=1=∑(x i−x)(y i −y)ni=1∑n i=1(x i −x)2，a =y −b x ；②χ2=n(ad−bc)2(a+b)(c+d)(a+c)(b+d)，n ＝a +b +c +d ；③参考数据：308＝4×77．解：（1）r 1=∑(u i −u)(y −y)12i=1√∑(u i −u)2i=1∑(y i −y)2i=1=3125000×200=2150025000=4350=0.86，r 2=∑(x i −x)(v i −v)12i=1√∑(x i −x)2i=1∑(v i −v)2i=1=14√770×0.308=1477×0.2=1011≈0.91，则|r1|＜|r2|，因此从相关系数的角度，模型y＝eλx+t的拟合程度更好．（2）先建立v关于x的线性回归方程，由y＝eλx+t，得lny＝t+λx，即v＝t+λx，由于λ=∑(x i−x)(v i−v)12i=1∑(x i−x)212i=1=14770≈0.018，t=v−λx=4.20−0.018×20=3.84，所以v关于x的线性回归方程为v=0.02x+3.84，所以lny=0.02x+3.84，则y=e0.02x+3.84．（3）零假设为H0：对新款式瓷器喜爱程度与年龄无关，χ2=(200×150−100×150)2350×250×300×300≈0.029＜10.828，根据小概率α＝0.001独立性检验，没有充分证据推断H0不成立，即H0成立，该地区对新款式瓷器喜爱程度与年龄无关．22．（12分）已知函数f（x）＝x2（lnx﹣a），a为实数．（1）求函数f（x）的单调区间；（2）若函数f（x）在x＝e处取得极值，f′（x）是函数f（x）的导函数，且f′（x1）＝f′（x2），x1＜x2，证明：2＜x1+x2＜e．解：（1）函数f（x）＝x2（lnx﹣a）的定义域为（0，+∞），f′（x）＝2x（lnx﹣a）+x＝x（2lnx﹣2a+1），令f′（x）＝0，所以lnx=2a−12，得x=e2a−12，当x∈(0，e 2a−12)，f′（x）＜0，当x∈(e 2a−12，+∞)，f′（x）＞0，所以函数f（x）递减区间为(0，e 2a−12)，递增区间为(e2a−12，+∞)．（2）证明：因为函数f（x）在x＝e处取得极值，所以x=e 2a−12=e，得a=32，所以f(x)=x2(lnx−32)，f′（x）＝x（2lnx﹣2）＝2x（lnx﹣1），令g（x）＝2x（lnx﹣1），g′（x）＝2lnx，因为当x＝1时，g′（x）＝0，所以当x∈（0，1），g′（x）＜0，当x∈（1，+∞），g′（x）＞0，所以函数g（x）在（0，1）单调递减，在（1，+∞）单调递增，又当x∈（0，e）时，g（x）＝2x（lnx﹣1）＜0，当x∈（e，+∞）时，g（x）＝2x（lnx﹣1）＞0，所以0＜x1＜1＜x2＜e．①先证x1+x2＞2，需证x2＞2﹣x1，因为x2＞1，2﹣x1＞1，下面证明g（x1）＝g（x2）＞g（2﹣x1），设t（x）＝g（2﹣x）﹣g（x），x∈（0，1），则f′（x）＝﹣g′（2﹣x）﹣g′（x），t′（x）＝﹣2ln（2﹣x）﹣2lnx＝﹣2ln[（2﹣x）x]＞0，所以t（x）在（0，1）上为增函数，所以t（x）＜t（1）＝g（1）﹣g（1）＝0，所以t（x1）＝g（2﹣x1）﹣g（x1）＜0，则g（2﹣x1）＜g（x1）＝g（x2），又因为g（x）在（1，+∞）单调递增，所以2﹣x1＜x2，即得x1+x2＞2，②下面证明：x1+x2＜e，因为x1∈（0，1），g（x1）＝2x1（lnx1﹣1）＜﹣2x1，当x∈（1，e）时，设h（x）＝g（x）﹣（2x﹣2e）＝2xlnx﹣4x+2e，因为在（1，e）上h′（x）＝2lnx﹣2＜0，所以h（x）在（1，e）上单调递减，所以h（x）＞h（e）＝2e﹣4e+2e＝0，所以h（x2）＞0，g（x2）＞2x2﹣2e，因为g（x1）＝g（x2），所以2x2﹣2e＜g（x2）＝g（x1）＜﹣2x1，即x1+x2＜e，所以2＜x1+x2＜e．。
