陕西省府谷县麻镇中学2014-2015学年高一上学期期末考试语文试题第Ⅰ卷阅读题（共70分）评卷人得分一、现代科技文阅读（6—9小题，12分，每小题3分）阅读下面的文字，完成6～9题。

从乐器的角度看，声音好当然是第一位的。

但关键是，怎样的琵琶声音才算好呢？这就像问上等巧克力的味道，实在是个用语言和文字难以表述的问题。

不过办法总是有的，直接、正面的回答不上，可以用间接、侧面的，最现成而著名的答案是白居易在其名篇《琵琶行》中的那句“大珠小珠落玉盘”。

然而，即便是专业琵琶界，有谁真听到过珍珠落在玉盘里的声音呢？再说，就算有人真听到过，多半也会失望的，因为“珠落玉盘”所发出的压根就不是“乐音”。

那么为什么一千多年，人们不但认可而且还无数次地引用这句话呢？我想它至少说出了琵琶在发音上的三个要点：颗粒状的发音形态；弹拨乐器而具有某些打击乐器的发音效果；声音上要具备珠和玉的美学品质。

我国历把“珠”和“玉”视为“珍宝”，或者说它们是中国人“美的理想”。

在大自然中，很少有接近球形正圆体的天成之物，而“珠”能接近正圆体，这恐怕是珠能引起美感的原因之一，所谓“物以稀为贵”。

也正因为如此，所以越接近正圆体的珠就越珍贵，称为“走盘珠”，其可贵即在浑圆与饱满。

而“玉”则致密、细腻，是一种“温润而有光泽的美石”，握在手里还有一种沉甸甸的分量感，这里“温”“润”“泽”都带有三点水，这使人联想起悦耳的“乐音”有“水灵灵”的特性。

其实珠也是一种美石——珍珠贝的“结石”，它与玉都有一种光彩，这光彩粗看并不“耀眼”、“逼人”，但细察则“绚烂之极”，即所谓东方人的含蓄之美。

说“在声音上要具备珠与玉的美学品质”，具体地也是笨拙地说，就是声音要具有圆润、饱满、指高音区的发音明亮；“堂”，指低音区的发音洪亮；“松”，指按弹时发音灵敏，余音强而长；“脆”，指发音清脆；“爆”，指发音坚实而有分量。

但由于这五条标准由已久，可见它们是针对“丝弦琵琶”而言的，因为“钢弦琵琶”只是20世纪60年代以40多年的事。

﹣4）2=64，故答案为：x2+（y﹣4）2=64．13．（5分）曲线y=x（3lnx+1）在点（1，1）处的切线方程为y=4x﹣3．【解答】解：求导函数，可得y′=3lnx+4，当x=1时，y′=4，∴曲线y=x（3lnx+1）在点（1，1）处的切线方程为y﹣1=4（x﹣1），即y=4x﹣3．故答案为：y=4x﹣3．14．（5分）直线tx+y+3=0与圆x2+y2=4相交于A、B两点，若，则实数t的范围．【解答】解：∵直线tx+y+3=0与圆x2+y2=4交于相异两点A、B，∴O点到直线tx+y+3=0的距离d＜2，又∵，由平行四边形可知，夹角为钝角的邻边所对的对角线比夹角为锐角的邻边所对的对角线短，∴和的夹角为锐角．圆心到直线的距离大于，综合可知＜d＜2，解得：故答案为：15．（5分）圆和圆相内切，若a，b∈R，且ab≠0，则的最小值为9．【解答】解：圆的圆心为C1（﹣2a，0），半径r1=2．圆的圆心为C2（0，b），半径r2=2．∵圆C1与圆C2相内切，∴|C1C2|=|r2﹣r1|=1，即=1，化简得4a2+b2=1．因此，=（4a2+b2）（）=5+（），∵≥=4，∴≥5+4=9，可得：当且仅当时，即a2=且b2=时，的最小值等于9故答案为：9三、解答题（共6小题，满分75分）16．（12分）下列函数的导数．（1）y=；（2）y=（x+1）（x+2）（x+3）．【解答】解：（1）y′=（）′==，（2）y=（x+1）（x+2）（x+3）=x3+6x2+11x+6，∴y′=3x2+12x+11x．17．（12分）已知椭圆C：+=1（a＞b＞0）的焦距为4，且过点P（，），求椭圆C的方程．【解答】解：因为焦距为4，即c=2，所以a2﹣b2=c2=4．又因为椭圆C过点P（，），所以+=1，解得a=2，b=2，从而椭圆C的方程为+=1．18．（15分）已知函数f（x）=e x（ax+b）﹣x2﹣4x，曲线y=f（x）在点（0，f（0））处切线方程为y=4x+4．（Ⅰ）求a，b的值；（Ⅱ）讨论f（x）的单调性，并求f（x）的极大值．【解答】解：（Ⅰ）∵f（x）=e x（ax+b）﹣x2﹣4x，∴f′（x）=e x（ax+a+b）﹣2x﹣4，∵曲线y=f（x）在点（0，f（0））处切线方程为y=4x+4∴f（0）=4，f′（0）=4∴b=4，a+b=8∴a=4，b=4；（Ⅱ）由（Ⅰ）知，f（x）=4e x（x+1）﹣x2﹣4x，f′（x）=4e x（x+2）﹣2x﹣4=4（x+2）（e x﹣），令f′（x）=0，得x=﹣ln2或x=﹣2∴x∈（﹣∞，﹣2）或（﹣ln2，+∞）时，f′（x）＞0；x∈（﹣2，﹣ln2）时，f′（x）＜0∴f（x）的单调增区间是（﹣∞，﹣2），（﹣ln2，+∞），单调减区间是（﹣2，﹣ln2）当x=﹣2时，函数f（x）取得极大值，极大值为f（﹣2）=4（1﹣e﹣2）．19．（12分）求过定点P（0，1）且与抛物线y2=2x只有一个公共点的直线方程．【解答】解：①设直线l的斜率等于k，则当k=0时，直线l的方程为y=1，满足直线与抛物线y2=2x仅有一个公共点，当k≠0时，直线l是抛物线的切线，设直线l的方程为y=kx+1，代入抛物线的方程可得：k2x2+（2k﹣2）x+1=0，根据判别式等于0，求得k=，故切线方程为y=x+1．②当斜率不存在时，直线方程为x=0，经过检验可得此时直线也与抛物线y2=2x相切．故所求的直线方程为：y=1，或x=0，或x﹣2y+2=0．20．（12分）已知圆C：（x﹣a）2+（y﹣2）2=4（a＞0）及直线l：x﹣y+3=0．当直线l被圆C截得的弦长为时，求（Ⅰ）a的值；（Ⅱ）求过点（3，5）并与圆C相切的切线方程．【解答】解：（Ⅰ）依题意可得圆心C（a，2），半径r=2，则圆心到直线l：x﹣y+3=0的距离，由勾股定理可知，代入化简得|a+1|=2，解得a=1或a=﹣3，又a＞0，所以a=1；（Ⅱ）由（1）知圆C：（x﹣1）2+（y﹣2）2=4，圆心坐标为（1，2），圆的半径r=2由（3，5）到圆心的距离为=＞r=2，得到（3，5）在圆外，∴①当切线方程的斜率存在时，设方程为y﹣5=k（x﹣3）由圆心到切线的距离d==r=2，化简得：12k=5，可解得，∴切线方程为5x﹣12y+45=0；②当过（3，5）斜率不存在直线方程为x=3与圆相切．由①②可知切线方程为5x﹣12y+45=0或x=3．21．（12分）双曲线与椭圆+=1有相同焦点，且经过点（，4），求其方程．【解答】解：椭圆的焦点为（0，±3），c=3，…（3分）设双曲线方程为，…（6分）∵过点（，4），则，…（9分）得a2=4或36，而a2＜9，∴a2=4，…（11分）双曲线方程为．…（12分）赠送—高中数学知识点【1.3.1】单调性与最大（小）值（1）函数的单调性②在公共定义域内，两个增函数的和是增函数，两个减函数的和是减函数，增函数减去一个减函数为增函数，减函数减去一个增函数为减函数．③对于复合函数[()]y

history．The first and earliest paper cutting was found in China 1，500years ago．But this traditional art is at risk of disappearing now．Luckily，Voyo Woo，a Chinese immigrant（移民）in America，is trying to bring this art back to life．One Saturday in 2014，Ms Woo held a paper cutting show at a shopping center near Washington．She got much fun and peace doing it．She hoped more people would enjoy it．Ms Woo began to study the art of paper cutting as a 14﹣year﹣old girl in her hometown in China．She said all the students at school had to learn paper cutting．But she had a deep love for it．So her teacher spent more time teaching her after class．Later，she won the second prize in a national painting and artcompetition．Ms Woo went to America after she finished college in 2008．Soon after that，she took part in an activity to promote（宣传）Chinese paper cutting．And then she was invited to show the art in many important activities．"It is important to promote this art to Americans or anyone who is interested in it．Maybe it will make this art more popular．"Woo said．From the art of paper cutting，people can know about Chinese cultural values，history and stories of people's life．Ms Woo uses the art as a tool to show Chinese culture to people who know little about it．Chinese art is not only for Chinese，but also for people all over the world．46．What did Ms Woo do in 2014？A．ShHe wonthe second prize in a national painting and art competition．B．She was invited to many activities to show paper cutting．C．She held a paper cutting show at a shopping center near Washington．D．She took part in an

happened when the telegraph（电报）was the fastest method of long﹣distance communication．One day，a young man went to an interview for a job as a Morse code operator（莫尔斯电码报务员）．Answering the ad in the newspaper，he went to the office address．When he arrived，he walked into a large，busy office filled with noise，including the sound of the telegraph．An office worker asked him to wait until he was called to go into the inner office．Seven other people were already in the waiting area for the interview．The young man sat down and waited with them．After a few minutes，the young man stood up，crossed the room to the door of the inner office，and walked right in．Naturally the other people wondered what was going on．They were sure that the young man made a mistake and would be refused．A few minutes later，however，the boss came out of the inner office with the young man and said to the other people，"Gentlemen，thank you very much for coming，but the young man has got the job．"The other people were surprised，and one of them said，"Wait a minute．I don't understand．He was the last to come in，and we never even got a chance to be interviewed．Yet he got the job．That's not fair!" The boss said，"I'm sorry，but all the time you've been sitting here，the telegraph has been sending out the following message in Mores code：‘If you understand this message，then come right in．The job is yours．'None of you heard it or understood it．This young man did．The job is this．"49．The young man got the information about the job from．A．the telegraph B．the newspaper C．an office worker D．a

office．53．（6分）The eagle has the longest life of its group．It can reach up to70years．But to reach this age，the eagle must make a hard andpainful decision．When an eagle reaches near 40，its short sharp beak becomesbent（弯曲的）．Its long and once flexible（灵活的）talonscan no longer catch animals or birds for food．And its old andheavy wings with thick feathers on its body make it difficult to fly．Then，the eagle has only two choices：to die or to go through apainful time of change which needs five months．When the eagle feels weak and is about to die，it goes to aplace far away on the top of a mountain and sits on a nest．For a new life，the eagle knocks its beak against a rock until it pulls its beak out．After pulling it out，the eagle waits for a new beak to grow．And then it pulls out its talons and old feathers．It takes the eagle five months to complete its change and get a new life．We can call it its rebirth．So it can live for 30more years．Like the ea gle，we human beings sometimes need to make some change to get out of our difficulty．In miserable condition，we have to change our ways of life．The changing may be very painful．But sometimes we have to throw off our old habits，memories and traditions．We can't go on with all our past burdens（重负）．53．Which of the following is TRUE according to the passage？A．When an eagle reaches near 40，its short sharp beak is still straight．B．For a new life，the eagle knocks its talons against a rock．C．If the eagle doesn't change itself，it will have a new life．D．The writer's idea is that we can't go on with all our past burdens．54．The underlined

have never heard about．And they can also see other cultures of the town from the windows of the buses．Besides，passengers'luggage（行李）is also interesting．It is common to see a happy dog's head getting out of somebody's bag or a lovely chicken"speaking cheerfully"under somebody's arm．Once on a bus in Peru，a farmer even tied a sheep to the top of the bus．It was quite surprising．In all，taking the bus
