It is because there are cash crops,and the countries need the money to service their debts.Notice that servicing a debt does not mean paying it off.It means just paying the interest .Western banks make vast profits from third world debt.We buy clothes that are manufactured in sweat shops by virtual slaves in poor parts of the world.We create mountains of waste.We demand cheap food,mindless of the fact that it is totally devoid of taste and is produced using chemicals that poison the land.We insist on our right to drive our own car wherever we want to go.The evil of the consumption culture is the way it makes us oblivious to the impact of our own behavior.Our main problem is not t hat we don’t know what to do about it.It is mustering the desire to do it.Questions 56—60Complete the following sentences with information given in the passage,using a maximum of four words for each sentence.56. At the beginning of the passage,the author states that there are ______ kinds of economy and he will talk about the one related to the majority of people.57. According to the passage,______ serve as the foundation of the whole economic system.58. Economists believe that the economy struggles to keep people feel like they are always ______.59. The reason poor countries like Ecuador and Kenya export their crops is to get money to ______.60. The aim of this passage is to make people recognize the ______ and thus be free to make their own choices in the consumption culture.Section B (10 marks)Questions 61-65 are based on the following passage.For more than a mile,the desert in southern Peru has a curious ruler-straight and tacksharp design made by rocks .The wandering mule paths that cross it only emphasize its precision.Throughout hundreds of square miles of arid plateau,other such markings around,most of them concentrated between the towns of Nazca and Palpa.Known as the Nazca Lines,they form a geometric mélange of quardrangles,triangles,and trapezoids .The markings also form spirals and flowers,narrow lines that extend more than five miles,and a desert zoo of giant creatures -birds ,reptiles ,whales,a monkey,and a spider-all made by stones whose patterns can only be seen from the air.Because some of the figures resemble the ones that decorate Nazca pottery,archaeologists attribute the lines to the Nazcas,a coastal people whose culture rose,flourished,and declined between 100 BC and AD 700.Making the patterns must have been extremely time-consuming.The Nazcas must havecleared millions of rocks to expose the lighter ground beneath them,piled the rocks in rows,and created designs that,in this nearly rainless region,can last thousands of years.But why did they construct them? Nobody really knows.There have been many guesses.Some say that they were prehistoric roads,or farms.Others say they were signals or offerings to celestial beings.It has also been suggested that they constitute a giant astronomical calendar,an almanac for farmers who wished to predict the return of water to valley streams.One study did ascertain that some of the lines point to solstice positions of the sun and moon in ancient times,as well as to the rising and setting points on the horizon of some of the bright stars.But none of the theories have proven to be correct.And so the mystery remains,including the most tantalizing question of all:why did the Nazcas create immense designs that they themselves could never see ,designs that people nowadays can only see from the air?One person who worked to find out the answer was Maria Reiche.For over forty years she photographed and charted “las lineas”,striving to complete a map of the hundreds of designs and figures of this area,which is some thirty miles long and threaded by the Pan American highway.This determined German -born mathematician slept on a camp cot behind her car on the rocky,grassless Peruvian “pampa”,and even when she was elderly,got up before daylight to conduct her research.She scorned the suggestion that the markings may have been airfields for outer -space visitors to earth during prehistoric times.“Once you remove the stones,the ground is quite soft,” she said.“I’m afraid the spacemen would have gotten stuck.”Although Maria Reiche was not able to find the answer ,she crusaded to preserve the patterns so that others following her might have a chance to do so.Questions 61 to 65Answer the following questions with the information given in the passage in a maximum of fifteen words for each question.61. Why do people name the patterns the Nazca Lines?62. Are there any definite reasons for the construction of Nazca Lines? If not,what does the author offer?63. Could those who built the Nazca Lines see the patterns? If not,how can people now see them?64. Did Maria Reiche believe the Nazca Lines have something to do with outer-space visitors? What was her reason?65. What’s Reiche’s contribution about the mystery of the Nazca Lines even though she had not solved it hers elf?Section C (10 marks)Questions 66 to 70 are based on the following passage.In the past ,most cities usually were the natural outgrowth of villages and towns that happened to prosper.Rome started out as a small village,as did Athens,Paris,London and New York.Of course,there were exceptions to this general rule.In ancient times,Alexandria in Egypt,and Saint Petersburg,were both planned cities.But for the most part,cities throughout history were not the products of deliberate thought.Today the reverse is true .Many nations,alarmed by the urban sprawl that has been gobbling up farmland and open countryside ,and appalled by the staggering urban problems in the central cities,have begun building new cities that are specifically designed to meet modern needs.Britain has long been a pioneer in planning new cities .As the first nation to become industrialized and urbanized,it faced traffic,slums and pollution long before anyone else.In 1898 an Englishman,Sir Ebenezer Howard,published a book called To-morrow:a Peaceful Path to Real Reform,in which he advocated a new form of urban growth and organization:the “garden city”.Such a city combined the beauty of nature-trees,grass,sunshine and fresh air -with all the advantages of city living,including an abundance of jobs,social and cultural centres and good shopping facilities .The garden city was to be fairly small int size and the inhabitants would have easy access to the countryside,while at the same time they would be close to their work.In 1899 Howard organized the Garden City Association and in 1903 and 1920 he built the first and the second garden city ,Letchworth and Welwyn Garden City .These projects encountered many difficulties and failed to arouse widespread enthusiasm.Nevertheless,both Welwyn and Letchworth survived and grew,and in later years-particularly after World War II -British planners looked at them with renewed interest.The war had given the British a painful lesson in the weakness of modern,heavily populated cities.Cities were not the places of refuge they had once been.One the contrary,the invention of the aeroplane had made them the most vulnerable targets for attack.Aerial warfare made it clear that people were far safer outside the great urban centres.It was better not to concentrate so much of the population and industrial resources in a few large cities,but to spread them out into many smaller towns and cities .Fast ,modern transportation methods made such dispersalpossible.Furthermore,these new towns-modeled on Howard’s garden cities-could also drain off the surplus population of the large cities,relieving the overcrowded conditions,housing shortages,slums and traffic jams that plagued them.Questions 66 to 68 Mark each statement as either true (T)or false (F)according to the passage.Questions 69—70 Translate the following sentences of the passage into Chinese .Remember to write the answers on the answer sheet.66. In the past,most cities were not planned and they just grew up spontaneously.正确错误67. Garden cities built by Howard never aroused widespread enthusiasm.正确错误68. It can be inferred that the author believes the construction of big cities is a mistake.正确错误69. Many nations,alarmed by the urban sprawl that has been gobbling up farmland and open countryside,and appalled by the staggering urban problems in the central cities,have begun building new cities that are specifically designed to meet modern needs.70. Furthermore,these new towns-modeled on Howard’s garden cities-could also drain off the surplus population of the large cities,relieving the overcrowded conditions,housing shortages,alums and traffic jams that plagued them.Section D (10 marks)Questions 71—75 are based on the following passage.Sport is ubiquitous.Sky TV has at least thirteen sports channels.Throughout the world there is a proliferation of newspapers and magazines totally dedicated to sport.Sports personalities have become cultural icons ,worshipped like movie -stars and sought after by sponsors and advertisers alike.Where sport was once for fun and amateurs,it is now the stuff of serious investment.Of course,sport has always mattered.But the point is that in the past sport knew its place.Now it invades areas of life where previously it had no presence:fashion,showbiz,business.It is a worldwide obsession.What is it that makes sport so enjoyable for so many? First,we seriously believe that sport is something we can all do,however badly or however well.Tens of thousands set off on the London and New York Marathons.Amateur footballmatches take place all over the world every weekend.Sport is a democratic activity.Second,sports stars are self-made people.Sport is dominated by athletes from ordinary backgrounds.This is why it is a classic means by which those from the poorest backgrounds can seek fame and fortune.Third,we enjoy watching sport because we like to see the supreme skill of those who act like gladiators in the modern arena.There is the excitement of not knowing who is going to win.No rock concert,no movie,no play can offer that kind of spontaneous uncertainty.This gut -wrenching experience can be shared with a crowd of fifty round a widescreen TV in a pub,or a thronging mass of 100,000 live in a stadium.The rise of sport has been accompanied by the growing prominence of sports stars.They have become public figures,hence in great demand for TV commercials.The rise of the sports star is mirrored by the rise of sports companies such as Nike and Adidas.“Sport probably does more to unify nations than any politician has ever been capable of”.So said Nelson Mandela.The only truly global occasions are the Olympics and World Cup,watched by thousands of millions across the world.These great sporting events bring together players and athletes from different races like no other.Not only that,but sport provides just about the only example of global democracy where the rich do not dominate on the contrary,Brazilians have long been supreme at football,the Kenyans at middle-distance running,and black Americans at boxing.However,there are signs of disquiet in this vast,global industry.The sheer volume of sport is reaching the bursting point for all but the most besotted fan.Overpaid tennis players and golfers fly endlessly in personal jets from one meaningless tournament to the next.Sport risks kelling itself through greed and over-exposure.The danger is that we will all become satiated and ultimately disillusioned.Questions 71 to 75Complete the summary below with information from the passage ,using no more thanthree words for each blank.Sport is now enjoying popularity all over the world.Besides the entertaining quality,it has turned into a kind of (71)______.Furthermore,the worldwide obsession to it leads to its (72)______ in many fields .There are three points which can shed a light on its unique charm:it being a democratic activity,athletes from ordinary backgrounds,and audience enjoying (73 )______ that they can’t get from other kinds of entertain ments .More importantly,sport is playing a significant role in (74)______ and offering global democracy.However,this global industry will probably be confronted with audiences’ (75)______ due to its over-exposure.Part V Translation (10 marks)Translate the following sentences into English by using the word or words given in brackets.Remember to write your answers on the answer sheet.76. 请大家在座位上坐好,系紧安全带,待飞机停稳后从紧急出口离开。

c03-NOIP2013初赛答案解析
一、单选题(15*1.5)1、A,一个字节有8个bit,32位整型变量占用4个字节,故选A。
2、A,二进制11.01转为十进制,(11.01)2 = 1*2+1+0*0.5+1*0.25 = (3.25)10 。
3、B,老和尚给小和尚讲的故事里边有故事本身,递归是函数内部调用函数本身,故选B,递归。
4、D,香农信息论鼻祖。
5、A,一定是满二叉树时拥有2个字节点的节点数最多,最下一层会有2013-1023=990个节点,于是倒数第二层会有990/2=495个节点有2个字节点,从第1层到倒数第三层共有1023-2^9=511个节点,且这些节点都是用2个子节点的节点,所以共有495+511=1006个,选A。
6、B,要使图不联通,只要其中某一个节点不连通即可,所有顶点度最少是3,所以最少需要删除3条边,选B。
7、D,此题最开始一眼扫到的时候脑子进水,跟学生将选B,O(n),实际上不是,计算F1需要1次,计算F2需要一次,计算Fn需要计算F(n-1)的次数加上F(n-2)的次数,所以其实就是计算Fn次,于是答案选择D,至于这个Fn到底是多大,数学上可以计算,它等于O(((1+sqrt(5))/2)^n).8、B,这个必须是B,没有什么好说的,中序遍历保证左边都是小于根的,右边都是大于根的,所以可以保证是一个有序序列。
9、D,A项6和17对11取余都是6发生冲突,B项10的平方和17的平方对11取余都是1发生冲突,C项6的两倍和17的两倍对11取余都是1发生冲突,D 项分别为1,2,3,4,不冲突。
10、D,IPV6地址是128位的。
谢谢网友指正!11、C,二分为6个和6个的顶点,此时边最多,有36条边。
12、B,我的学生几乎全选A去了,因为之前讲题只介绍过ASCII码,但是看到统一二字也应该想到Uni...前缀啊。
13、D,64位非零浮点数强制转换成32位浮点数,两个数会有大小上的细微差别,但不会发生符号变化,因为有专门的符号位。
