河北省邯郸市涉县第一中学2013--2014学年高三3月月考试卷(语文)

河北省邯郸市涉县第一中学2013--2014学年高三3月月考语文试卷本试卷分第Ⅰ卷(阅读题)和第Ⅱ卷(表达题)两部分。

满分150分。

考试用时150分钟。

第Ⅰ卷阅读题甲必考题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1—3题。

《公羊传》和《谷梁传》的史学价值由于孔子在文化史上的崇高地位和《春秋》的重要性,当《春秋》流传以后即吸引着许多学者对它研究、评论。

在儒家内部,既有着重从记载史事上加以补充、发展的《左传》,又有着重从解释《春秋》的文辞和“史义”上加以发挥的《公羊传》和《谷梁传》。

《公羊传》和《谷梁传》解释《春秋》的用辞和书法,体现出一种准确、凝炼的文风。

例如,《公羊传》僖公十六年,对经文“陨石于宋五。

是月,六鷁退飞,过宋都”,作了细致的说明。

《谷梁传》庄公七年,对经文“夏四月辛卯,昔,恒星不见”,同样有细致的解释,反映了中国史学史上的好传统。

在史实记载上,二传远不及《左传》丰富,但也具有重要的史料价值。

《公羊传》宣公六年,记载晋厉公骄佚暴虐的种种行为,以及“赵穿缘民众不悦,起弑灵公,然后迎赵盾而入”的曲折经过;《谷梁传》僖公九年所谓葵丘之会的盟辞,“毋壅泉,毋讫籴,毋易树子,毋以妾为妻,毋使妇人与国事”,这些都是反映春秋时期社会情况的宝贵史料。

其他可与《左传》相补充的史实还有不少。

二传对于史学发展的意义,更重要的是体现在对历史思想产生的影响上。

《谷梁传》主张“著以传著,疑以传疑”,指出历史家应遵从忠实记载史实的原则,并能够将这一原则贯彻到自己的著作之中。

如谴责宋襄公拘守成说,“失民”,“以其不教民战,则是弃其师也”等等,体现了上述忠实于历史的原则。

《公羊传》的历史思想比《谷梁传》更为丰富,其影响也更深远。

在汉代,公羊学大显于世。

魏晋以后虽经一千多年的消沉,至鸦片战争前后却重新复兴,而且风靡一时,成为近代维新运动的思想武器,并且是十九世纪、二十世纪之交中国思想界接受西方进化论的思想基础。

The new shoes were the name-brandof another player, Robert Ryann, who was for his amazing work in the community.Travis’s hands ; his heart stopped. It wasn't that the Ryann shoesweren’t nice, but what would his friends think ?They were the wrong shoes and Travis would be by the other players. Whenhe looked up into his dad' s eyes, however, Travis decided he not tell him."'Thanks, Dad. I was really hoping for shoes," Travis said as he pulled the shoesout of the box.Next morning his dad drove him to school. When they in front of his destination, Travis slowly opened the car door.

We lived on a farm and, in the winter especially, we were quitecut off from the outside world. As soon as I left school, I packed my bags andmoved to the capital. However, I soon discovered that city life has its problemstoo.One big disadvantage is money---it costs so much to go out, not to mention basicslike food and housing. Another disadvantage is pollution. I suffer fromasthma(哮喘), and at times the air is so bad that I am afraid to go outside.Then there is the problem of travelling round. Although I have a car, I seldomuse it because of the traffic jams. One choice is to go by bicycle, but thatcan be quite dangerous.Of course there are advantages. First, there is so much to do in the city,whatever your tastes in culture or entertainment. Besides, there are wonderfuljobs and greater chances of moving to a more important job or position. Finally,if you like shopping, the variety of goods is very surprising---and, what ismore, shops are often only a short walk away.Is life better then, in the city? Perhaps it is, when you are in your teens(十几岁) or twenties. However, as you get older, and especially if you have smallchildren, the peace of the countryside may seem preferable. I certainly hopeto move back there soon.36.What was the writer always thinking about when he was a child?A. Staying on the farmB. Moving to the countrysideC. Leaving home for the cityD. Running away from the school37.Which of the following is true about the writer?A. He is very old now.B. He is in good health.C. He prefers driving a car.D. He lives in the city now.38.In the passage, the writer tries to _______.A. express his opinions about way of lifeB. describe his life in the countrysideC. show an interest in the outside worldD. persuade the reader to live in the city39.How is the passage mainly developed?A. By inferringB. By comparingC. By listing examplesD. By giving explanationsThe director brings out the best of the characters in the movie ToyStory. The movie portrays the emotions of the toys. How beautifullythe and so on have turned up in this movie!40.According to the text, the film Forrest Gump is aimed at improving the viewers’ _____.A. teamworkB. self-confidenceC. ImaginationD. friendship41.How much do they have to pay if eight-year-old Jason goes to see the film Dumbo with his parents?A. $ 10.B. $ 20.C. $ 30.D. $ 45.42.Who are the main target audience of the movies mentioned in the text?A. Parents.B. Teachers.C. Children.D. Clerks.43.What emotions have appeared in the film Toy Story EXCEPT__________?A. friendshipB. loveC. leadershipD. GenerosityA new generation addiction is quickly spreading all over the world. Weboholism (网瘾), a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.Ten years ago, no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users. Such behavior has seriously affected teenagers and college students. They are likely to log(写日志) on computers and spend long hours at different websites.They become hooked (着迷) on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this ad diction influences their grades and success at school. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life. They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.Because of the change in their behavior, they begin to isolate themselvesfrom society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real live friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect all the world.44.The main idea of the passage is about__________.A. the cause of weboholismB. the advantage of weboholismC. the popularity of weboholismD. the effect of weboholism45.We can infer from the passage that_______.A. weboholism has the greatest effect on teenagersB. students can hardly balance real and virtual lifeC. people are addicted to games on the InternetD. virtual life is more vivid and attractive than real life.46.Which of the following is NOT true of weboholism?A. It contributes to the development of the web.B. The chat room language may change social culture.C. The problem will be getting more and more serious later.D. People addicted to the web often become inactive in real life.Speaking from my past experience, it is very difficult to find good friends that you can trust but once you have found them, they are worth keeping forever! Therefore, I think friendship is the most important relationship that anybody could have.The qualities I look for in a friend are a good sense of humor but sensitivity when it matters. Also that friend would have to be strong-minded and highly spirited. I think that these qualities are the key qualities to look for in a good friend.Even the strongest friends can still have arguments, although usually about more serious topics, rather than the usual teenage childish arguments. Some matters can seriously affect a friendship. If one of your friends started experimenting with harmful and dangerous drugs, what would you do ? A good friend would try to help as much as possible, whereas a bad example of a friend would simply shrug(耸肩) and turn a blind eye.Not only the bad things affect friendship ---- good activities do too. Such as bonding with one another, not just by going out on a night with them but by spending quality time with them and talking to each other, which indicates a good ability to communicate. This is a key aspect of a good friendship. Good friends do not always have to be in the same age group as you. I have a good friend and she is 47 years old and I am 16.Unfortunately, some people lose contact with their friends as they grow older, which is a sad way to lose a good friend.I think friendship is one of the most important things in life because if you have no friends you will have no happiness.47.According to the author, true friendship _______.A. is easy to getB. deepens with timeC. needs managementD. affects one’s happiness48.Paragraph 3 is mainly about______.A. why drugs are bad for teenagersB. problems that will test friendshipC. ways that help avoid argumentsD. whether a friend is trustworthy49.According to the author, which matters least in friendship?A. Age.B. Sensitivity.C. Sense of humor.D. Communication ability.50.Which of the following saying can match the author’s view on friendship?A. Old friends and old wines are best.B. A friend without faults will never be found.C. A life without a friend is a life without the sun.D. a friend to everybody is a friend to nobody.51.Sometime in February, my teacher told us about the city speech contest, its topic was “People who have overcome difficulties in their lives”. I thought of my grandma would be my perfect topic. Then I carefully prepared for contest.A couple of weeks later, after the first round I was choosing to be one of the seven finalists! The final was held soon. I was the sixth to presenting the speech. How a relief when I finished it! After the last person finished, the judge made their final decisions and announced that I have won first prize. The audience were going wildly clapping and cheering! I was extremely happy. It was such exciting a moment that I will always remember it.52.假定你是李华,正在一所英国学校学习暑假课程,遇到一些困难,希望得到学校辅导中心(Learning Center)的帮助。

(1)解 因为f (x )是R 上的奇函数,故f (0)=0,即-1+b 2+a =0,解得b =1, 从而有f (x )=-2x +12x +1+a .又由f (1)=-f (-1)知-2+14+a =--12+11+a,解得a =2.∴f(x)=12⎝⎛⎭⎪⎫1-2x2x+1. ∴a=2,b=1.(2)证明设x1<x2,f(x1)-f(x2)=1-2x12(2x1+1)-1-2x22(2x2+1)=(1-2x1)(1+2x2)-(1-2x2)(1+2x1)2(2x1+1)(2x2+1)=2x2-2x1(2x1+1)(2x2+1).∵x1<x2,则2x2-2x1>0,∴f(x1)>f(x2).故f(x)是R上的减函数.(3)解由(2)知f(x)在R上为减函数,又因为f(x)是奇函数,从而不等式f(t2-2t)+f(2t2-k)<0等价于f(t2-2t)<-f(2t2-k)=f(-2t2+k).因为f(x)是R上的减函数,由上式推得t2-2t>-2t2+k. 即对一切t∈R有3t2-2t-k>0恒成立,从而Δ=4+12k<0,解得k<-1 3.18.解(1)由题意得a(sin A-sin B)+b sin B=c sin C,由正弦定理,得a(a-b)+b2=c2,即a2+b2-c2=ab,由余弦定理,得cos C=a2+b2-c22ab=12,结合0<C<π,得C=π3.(2)由a2+b2=6(a+b)-18,得(a-3)2+(b-3)2=0,从而得a=b=3,所以△ABC的面积S=12×32×sinπ3=934.19.解(1)可判定点(2,-6)在曲线y=f(x)上.∵f′(x)=(x3+x-16)′=3x2+1.∴f′(x)在点(2,-6)处的切线的斜率为k=f′(2)=13.∴切线的方程为y-(-6)=13(x-2),即13x-y-32=0.(2)设切点为(x0,y0),则直线l的斜率为f′(x0)=3x20+1,∴直线l的方程为y=(3x20+1)(x-x0)+x30+x0-16.又∵直线l 过点(0,0),∴0=(3x 20+1)(-x 0)+x 30+x 0-16,整理得x 30=-8,∴x 0=-2, ∴y 0=(-2)3+(-2)-16=-26, k =3×(-2)2+1=13.∴直线l 的方程为y =13x ,切点坐标为(-2,-26). (3)∵切线与直线y =-x4+3垂直, ∴切线的斜率k =4.设切点的坐标为(x 0,y 0),则f ′(x 0)=3x 20+1=4, ∴x 0=±1,∴⎩⎨⎧ x 0=1,y 0=-14或⎩⎨⎧x 0=-1,y 0=-18.所以切线方程为y -(-14)=4(x -1)或y -(-18)=4(x +1). 即4x -y -18=0或4x -y -14=0.20.解 (1)因f (x )=ax 3+bx +c ,故f ′(x )=3ax 2+b , 由于f (x )在点x =2处取得极值c -16, 故有⎩⎨⎧ f ′(2)=0,f (2)=c -16,即⎩⎨⎧12a +b =0,8a +2b +c =c -16.化简得⎩⎨⎧ 12a +b =0,4a +b =-8,解得⎩⎨⎧a =1,b =-12. (2)由(1)知f (x )=x 3-12x +c ,f ′(x )=3x 2-12.令f ′(x )=0,得x =-2或2,当x ∈(-∞,-2)时,f ′(x )>0,故f (x )在(-∞,-2)上为 增函数;当x ∈(-2,2)时,f ′(x )<0,故f (x )在(-2,2)上为减函数; 当x ∈(2,+∞)时,f ′(x )>0,故f (x )在(2,+∞)上为增函数.由此可知f (x )在x =-2处取得极大值f (-2)=16+c ,f (x )在x =2处取得极小值f (2)=c -16.由题设条件知,16+c =28,解得c =12,此时f (-3)=9+c =21,f (3)=-9+c =3,f (2)=c -16=-4,因此f (x )在[-3,3]上的最小值为f (2)=-4.21.解 (1)由|m +n |=3,得m 2+n 2+2m ·n =3,即1+1+2⎝ ⎛⎭⎪⎫cos 3A 2cos A 2+sin 3A 2sin A 2=3, ∴cos A =12.∵0<A <π,∴A=π3.(2)∵|AC→|+|AB →|=3|BC →|,∴sin B +sin C =3sin A , ∴sin B +sin ⎝ ⎛⎭⎪⎫2π3-B =3×32, 即32sin B +12cos B =32,∴sin ⎝ ⎛⎭⎪⎫B +π6=32.∵0<B <2π3,∴π6<B +π6<5π6, ∴B +π6=π3或2π3,故B =π6或π2. 当B =π6时,C =π2;当B =π2时,C =π6.故△ABC 是直角三角形.。

天津一中2013—2014学年高三数学一月考试卷(理科)一、选择题:(共40分,每小题5分,每小题给出的四个选项中,只有一项符合题目要求) 1.有关下列命题的说法正确的是A.命题“若x 2=1,则x=1”的否命题为:若“x 2=1则x ≠1” B.“1x =-”是“2560x x --=”的必要不充分条件C.命题“∃x ∈R,使得x 2+x+1<0”的否定是:“∀x ∈R,均有x 2+x+1<0” D.命题“若x=y,则sinx=siny ”的逆否命题为真命题 【答案】D【解析】若x 2=1,则x=1”的否命题为21x ≠,则1x ≠,即A 错误。

若2560x x --=,则6x =或1x =-,所以“1x =-”是“2560x x --=”的充分不必要条件,所以B 错误。

∃x ∈R,使得x 2+x+1<0的否定是∀x ∈R,均有210x x ++≥,所以C 错误。

命题若x=y,则sinx=siny 正确,所以若x=y,则sinx=siny 的逆否命题也正确,所以选D.2.定义在R 上的偶函数f(x),当x ∈[0,+∞)时,f(x)是增函数,则f(-2),f(π),f(-3)的大小关系是 A.f(π)>f(-3)>f(-2) B.f(π)>f(-2)>f(-3)C.f(π)<f(-3)<f(-2)D.f(π)<f(-2)<f(-3) 【答案】A【解析】因为函数是偶函数,所以(2)(2),(3)(3)f f f f -=-=,又函数在[0,)+∞上是增函数,所以由(2)(3)()f f f π<<,即(2)(3)()f f f π-<-<,选A.3.函数f(x)=sin2x-4sin 3xcosx(x ∈R)的最小正周期为 A.8π B.4π C.2π D.π【答案】C【解析】221()sin 22sin 2sin sin 2(12sin )sin 2cos 2sin 42f x x x x x x x x x =-=-==,所以函数的周期为2242T πππω===,选C. 4.设函数sin()3y x π=+(x ∈R),则f(x)A.在区间[-π,2π-]上是减函数 B.在区间27[,]36ππ上是增函数 C.在区间[8π,4π]上是增函数 D.在区间5[,]36ππ上是减函数 【答案】B 【解析】当2736x ππ≤≤时,2733363x πππππ+≤+≤+,即332x πππ≤+≤,此时函数sin()3y x π=+单调递减,所以sin()3y x π=+在区间27[,]36ππ上是增函数,选B. 5.在∆ABC 中,A,B,C 为内角,且sin cos sin cos A A B B =,则∆ABC 是 A.等腰三角形 B.直角三角形C.等腰直角三角形D.等腰或直角三角形【答案】D【解析】由s i n c o s s i n c A A B B =得sin 2sin 2sin(2)A B B π==-,所以22A B =或22A B π=-,即A B =或2A B π+=,所以三角形为等腰或直角三角形,选D.6.,,x y z 均为正实数,且22log x x =-,22log y y -=-,22log z z -=,则 A. x y z << B.z x y << C.z y x << D.y x z<<【答案】A【解析】因为,,x y z 均为正实数,所以22log 1x x =->,即2log 1x <-,所以102x <<。
