1. 必修五Unit 1 JOHN SNOW DEFEATS “KING CHOLERA”约翰斯诺击败“霍乱王” John Snow was a famous doctor in London - so expert, indeed, that he attended Queen Victoria as her personal physician.约翰斯诺是伦敦一位著名的医生他的确医术精湛，因而成为照料维多利亚女王的私人医生。But he became inspired when he thought about helping ordinary people exposed to cholera.但他一想到要帮助那些得了霍乱的普通百姓时，他就感到很振奋。This was the deadly disease of its day.霍乱在当时是最致命的疾病，Neither its cause nor its cure was understood.人们既不知道它的病源，也不了解它的治疗方法。So many thousands of terrified people died every time there was an outbreak.每次霍乱暴发时，就有大批惊恐的老百姓死去。John Snow wanted to face the challenge and solve this problem.约翰斯诺想面对这个挑战，解决这个问题。He knew that cholera would never be controlled until its cause was found.他知道，在找到病源之前，霍乱疫情是无法控制的。He became interested in two theories that possibly explained how cholera killed people.斯诺对霍乱致人死地的两种推测都很感兴趣。The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims.一种看法是霍乱病毒在空气中繁殖着，像一股危险的气体到处漂浮，直到找到病毒的受害者为止。The second suggested that people absorbed this disease into their bodies with their meals.第二种看法是人们在吃饭的时候把这种病毒引入体内的。From the stomach the disease quickly attacked the body and soon the affected person died.病从胃里发作而迅速殃及全身，患者就会很快地死去。John Snow suspected that the second theory was correct but he needed evidence.斯诺推测第二种说法是正确的，但他需要证据。So when another outbreak hit London in 1854, he was ready to begin his enquiry.因此，在1854年伦敦再次暴发霍乱的时候，约翰斯诺着手准备对此进行调研。As the disease spread quickly through poor neighbourhoods, he began to gather information.当霍乱在贫民区迅速蔓延的时候，约翰斯诺就开始收集资料。In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days.他发现特别在两条街道上霍乱流行的很严重，在10天之内就死去了500多人。He was determined to find out why.他决心要查明其原因。First he marked on a map the exact places where all the dead people had lived.首先，他在一张地图上标明了所有死者住过的地方。This gave him a valuable clue about the cause of the disease.这提供了一条说明霍乱起因的很有价值的线索。Many of the deaths were near the water pump in Broad Street (especially numbers 16, 37, 38 and 40).许多死者是住在宽街的水泵附近（特别是这条街上16、37、38、40号）。He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street) had had no deaths.他发现有些住宅（如宽街上20号和21号以及剑桥街上的8号和9号）却无人死亡。He had not foreseen this, so he made further investigations.他以前没预料到这种情况，所以他决定深入调查。He discovered that these people worked in the pub at 7 Cambridge Street.他发现，这些人都在剑桥街7号的酒馆里打工，They had been given free beer and so had not drunk the water from the pump.而酒馆为他们免费提供啤酒喝，因此他们没有喝从宽街水泵抽上来的水。It seemed that the water was to blame.看来水是罪魁祸首。Next, John Snow looked into the source of the water for these two streets.接下来，约翰斯诺调查了这两条街的水源情况。He found that it came from the river polluted by the dirty water from London.他发现，水是从河里来的，而河水被伦敦排出的脏水污染了。He immediately told the astonished people in Broad Street to remove the handle from the pump so that it could not be used.他马上叫宽街上惊慌失措的老百姓拆掉水泵的把手。这样，水泵就用不成了。Soon afterwards the disease slowed down.不久，疫情就开始得到缓解。He had shown that cholera was spread by germs and not in a cloud of gas.他证明了霍乱是由病菌而不是由气体传播的。In another part of London, he found supporting evidence from two other deaths that were linked to the Broad Street outbreak.在伦敦的另一个地区，他从两个与宽街暴发的霍乱有关联的死亡病例中发现了有力的证据。A woman, who had moved away from Broad Street, liked the water from the pump so much that she had it delivered to her house every day.有一位妇女是从宽街搬过来的，她特别喜欢那里的水，每天都要派人从水泵打水运到家里来。Both she and her daughter died of cholera after drinking the water.她和她的女儿喝了这种水，都得了霍乱而死去。With this extra evidence John Snow was able to announce with certainty that polluted water carried the virus.有了这个特别的证据，约翰斯诺就能够肯定地宣布，这种被污染了的水携带着病菌。To prevent this from happening again, John Snow suggested that the source of all the water supplies be examined.为了防止这种情况的再度发生，约翰斯诺建议所有水源都要经过检测。The water companies were instructed not to expose people to polluted water any more.自来水公司也接到指令，不能再让人们接触被污染的水了。Finally King Cholera was defeated.最终，“霍乱王”被击败了。2. 必修五Unit 1 COPERNICUS REVOLUTIONRRY THEORY哥白尼的革命性理论Nicolaus Copernicus was frightened and his mind was confused.尼古拉哥白尼被吓得心烦意乱的。Although he had tried to ignore them, all his mathematical calculations led to the same conclusion: that the earth was not the centre of the solar system.虽然他曾经试着不去理睬那些数字，然而他所有的数学计算都得出了一个相同的结论：地球不是太阳系的中心。Only if you put the sun there did the movements of the other planets in the sky make sense.只有当你把太阳放在中心位置上，天空中其他行星的运动才能说得清楚。Yet he could not tell anyone about his theory as the powerful Christian Church would have punished him for even suggesting such an idea.他的这个理论可不能告诉任何人，因为即使他只暗示有这种想法，他都会受到强大的基督教会势力的惩罚。They believed God had made the world and for that reason the earth was special and must be the centre of the solar system.教会认为世界是上帝创造的，正因为如此，地球就具有特殊的意义，它必定要成为太阳系的中心。The problem arose because astronomers had noticed that some planets in the sky seemed to stop, move backward and then go forward in a loop.这样，问题就来了，因为天文学家以前发现过，天上有些行星停顿下来，往后移动，然后再成环状向前移动，Others appeared brighter at times and less bright at others.而其他行星看上去有时亮些，有时又不怎么亮。This was very strange if the earth was the centre of the solar system and all planets went round it.如果地球是太阳系的中心，而所有行星环绕着地球转的话，那么这种现象就很奇怪了。Copernicus had thought long and hard about these problems and tried to find an answer.哥白尼对这些问题曾经苦苦思索过很久，试图找出问题的答案。He had collected observations of the stars and used all his mathematical knowledge to explain them.他曾经收集过观察星球的数据，并且利用他的全部数学知识来解释这些数据。But only his new theory could do that.但是只有他的新理论才能作出解释。So between 1510 and 1514 he worked on it, gradually improving his theory until he felt it was complete.于是，他在1510至1514年期间从事这项研究，逐步修改他的理论，直到他感到完善时为止。In 1514 he showed it privately to his friends.1514年，他把他的新理论私下里给他的朋友们看。The changes he made to the old theory were revolutionary.他对旧理论的修改是具有革命性的。He placed a fixed sun at the centre of the solar system with the planets going round it and only the moon still going round the earth.他把太阳固定在太阳系的中心位置上，而行星则围绕着太阳转，只有月球仍然绕着地球转。He also suggested that the earth was spinning as it went round the sun and this explained changes in the movement of the planets and in the brightness of the stars.他还提出地球在围绕太阳转的同时，它本身还自转，这样就说明了行星运动的变化情况以及星球亮度问题。His friends were enthusiastic and encouraged him to publish his ideas, but Copernicus was cautious.他的朋友都热情地鼓励他把他的想法公之于世，而他却小心谨慎，He did not want to be attacked by the Christian Church, so he only published it as he lay dying in 1543.他不想遭到基督教会的攻击，所以他直到1543年临终之前才公布了这一观点。Certainly he was right to be careful.当然，他小心谨慎是对的。The Christian Church rejected his theory, saying it was against Gods idea and people who supported it would be attacked.基督教会拒绝接受他的理论，说这种理论违背了上帝的旨意，而支持这种理论的人都会受到打击。Yet Copernicus theory is now the basis on which all our ideas of the universe are built.然而哥白尼的理论却是我们宇宙观赖以建立的基础。His theory replaced the Christian idea of gravity, which said things fell to earth because God created the earth as the centre of the universe.他的理论还改变了基督教对地心引力的看法，他们认为物体往地球上掉落是因为上帝创造了地球，而地球正是宇宙的中心。Copernicus showed this was obviously wrong.哥白尼表明这是明显错误的。Now people can see that there is a direct link between his theory and the work of Isaac Newton, Albert Einstein and Stephen Hawking.如今人们可以看到，他的这些想法与艾萨克牛顿、阿尔伯特爱因斯坦以及斯蒂芬霍金等人的研究都有着直接的联系。3. 必修五Unit 2 PUZZLES IN GEOGRAPHY 地理之谜 People may wonder why different words are used to describe these four countries: England, Wales, Scotland and Northern Ireland.人们也许觉得奇怪，为什么用来描述英格兰、威尔士、苏格兰和北爱尔兰这四个国家的词语不太一样。You can clarify this question if you study British history.但如果你学过英国历史，就能弄清楚这个问题。First there was England. Wales was linked to it in the thirteenth century.首先是英格兰。威尔士于13世纪同英格兰联合了起来。Now when people refer to England you find Wales included as well.如今只要有人提起英格兰，你就会发现威尔士总是包括在内的。Next England and Wales were joined to Scotland in the seventeenth century and the name was changed to Great Britain.接着，英格兰、威尔士同苏格兰于17世纪联合了起来，名字就改成了“大不列颠”。Happily this was accomplished without conflict when King James of Scotland became King of England and Wales as well.令人庆幸的是，当苏格兰的詹姆斯国王成为英格兰和威尔士的国王时，这三个国家和平地实现了联合。Finally the English government tried in the early twentieth century to form the United Kingdom by getting Ireland connected in the same peaceful way.最后，英国政府打算于20世纪初把爱尔兰也同另外三个国家和平联合起来以形成联合王国。However, the southern part of Ireland was unwilling and broke away to form its own government.然而，爱尔兰的南部却不愿意而分离出去了，并建立了自己的政府。So only Northern Ireland joined with England, Wales and Scotland to become the United Kingdom and this was shown to the world in a new flag called the Union Jack.因此只有北爱尔兰同英格兰、威尔士、苏格兰联合起来，而组成了联合王国，这一点从新的联合王国国旗上就可以看得出来。To their credit the four countries do work together in some areas (eg, the currency and international relations), but they still have very different institutions.值得赞扬的是，虽然这四个国家的确在一些方面共同合作，例如在货币和国际关系方面；但是它们在制度上仍然存在很大的区别。For example, Northern Ireland, England and Scotland have different educational and legal systems as well as different football teams for competitions like the World Cup!例如，北爱尔兰、英格兰和苏格兰在教育体制和立法体制上都存在着差异。在参加像世界杯之类的比赛时，它们有着各自的足球队。England is the largest of the four countries, and for convenience it is divided roughly into three zones.在这四个国家中，英格兰是最大的。为了方便起见，它大致可以划分为三个地区。The zone nearest France is called the South of England, the middle zone is called the Midlands and the one nearest to Scotland is known as the North.最靠近法国的那个地区叫做英格兰南部，中部地区叫做英格兰中部，最靠近苏格兰的那个地区叫做英格兰北部。You find most of the population settled in the south, but most of the industrial cities in the Midlands and the North of England.你可以看到英国的大部分人口聚居在南部，而多数大工业城市都位于中部和北部。Although, nationwide, these cities are not as large as those in China, they have world-famous football teams and some of them even have two!尽管，英国任何一个城市都不像中国的城市那样大，但是他们都有着自己的享有威名的足球队，有的城市甚至还有两个队。It is a pity that the industrial cities built in the nineteenth century do not attract visitors.很遗憾，这些建于19世纪的工业城市对游客并没有吸引力。For historical architecture you have to go to older but smaller towns built by the Romans.要找历史性建筑你得去更古老的、比较小些的由古罗马人建造的城镇。There you will find out more about British history and culture.在那儿你才可能找到更多的有关英国历史和文化的东西。The greatest historical treasure of all is London with its museums, art collections, theatres, parks and buildings.最具历史意义的宝地是伦敦。那儿有博物馆，有艺术珍品、剧院、公园和各种建筑物。It is the centre of national government and its administration.它是全国的政治中心。It has the oldest port built by the Romans in the first century AD, the oldest building begun by the Anglo-Saxons in the 1060s and the oldest castle constructed by later Norman rulers in 1066.它有公元一世纪由罗马人建造的最古老的港口，有由盎格鲁撒克逊人始建于11世纪60年代的最古老的建筑，还有公元1066年由后来的诺曼人统治者建造的最古老的城堡。There have been four sets of invaders of England.曾经有四批侵略者到过英国。The first invaders, the Romans, left their towns and roads.最早的入侵者是古罗马人，他们留下了他们的城镇和道路。The second, the Anglo-Saxons, left their language and their government.接着是盎格鲁撒克逊人，留下了他们的语言和政体。The third, the Vikings, influenced the vocabulary and place-names of the North of England, and the fourth, the Normans, left castles and introduced new words for food.第三是斯堪的纳维亚人，他们对词汇和北部的地名造成了一定影响；第四是诺曼人，他们留下了城堡和新的食物名称的词语。If you look around the British countryside you will find evidence of all these invaders.如果你到英国乡间去看看，你就会找到所有这些入侵者的痕迹。You must keep your eyes open if you are going to make your trip to the United Kingdom enjoyable and worthwhile. 如果想使你的英国之旅不虚此行又有意义，你就必须留心观察。4. 必修五Unit 2 SIGHTSEEING IN LONDON伦敦观光记 Worried about the time available, Zhang Pingyu had made a list of the sites she wanted to see in London.由于担心时间不够，张萍玉早就把她想要在伦敦参观的地点列了一张单子。Her first delight was going to the Tower. It was built long ago by the Norman invaders of AD 1066.她最先想参观的地方是伦敦塔，它是很久以前由入侵的诺曼人在公元1066年修建的。Fancy!This solid stone, square tower had remained standing for one thousand years. 真是太棒了！这个坚实的用石头砌的方形塔已经在那儿屹立一千年了。Although the buildings had expanded around it, it remained part of a royal palace and prison combined.尽管在塔的四周扩建了一些建筑，但它仍然是皇宫和监狱联合体的一个组成部分。To her great surprise, Zhang Pingyu found the Queens jewels guarded by special royal soldiers who, on special occasions, still wore the four-hundred-year-old uniform of the time of Queen Elizabeth I.让张萍玉很惊讶的是，她发现女王的珠宝由皇家的特别卫士守护着，而这些卫士在一些特殊的日子仍然穿着400年前伊丽莎白一世女王时代的制服。There followed St Pauls Cathedral built after the terrible fire of London in 1666.接着参观的是圣保罗大教堂，它是公元1666年伦敦大火以后建造的，It looked splendid when first built!刚建成的时候，它看起来真是金碧辉煌。Westminster Abbey, too, was very interesting.伦敦威斯敏斯特大教堂也是很有意思的地方，It contained statues in memory of dead poets and writers, such as Shakespeare.里面珍藏着一些已故诗人和作家的雕像，例如莎士比亚的雕像。Then just as she came out of the abbey, Pingyu heard the famous sound of the clock, Big Ben, ringing out the hour.正当萍玉从大教堂往外走的时候，她听到了著名的大本钟在整点敲响的钟声。She finished the day by looking at the outside of Buckingham Palace, the Queens house in London.她参观了女王伦敦住所白金汉宫的外景，以此结束了一天的观光。Oh, she had so much to tell her friends!啊，她要同朋友们讲的实在太多了！ The second day the girl visited Greenwich and saw its old ships and famous clock that sets the world time.第二天，萍玉姑娘参观了格林尼治天文台，看到了古老的轮船和那座著名的为世界定时的时钟。What interested her most was the longitude line.她最感兴趣的是那条通过天文台的经线。It is an imaginary line dividing the eastern and western halves of the world and is very useful for navigation.这是一条假想的线，它把世界分成东西两半球，从而有利于航海。It passes through Greenwich, so Pingyu had a photo taken standing on either side of the line.这条线穿过格林尼治，萍玉就跨着这条线拍了一张照片。The last day she visited Karl Marxs statue in Highgate Cemetery.最后一天，她参观了伦敦海洛特公墓里的卡尔马克思的雕像。It seemed strange that the man who had developed communism should have lived and died in London.这似乎是一件怪事：这位发展了共产主义的人竟然在伦敦生活过，并且在伦敦去世。Not only that, but he had worked in the famous reading room of the Library of the British Museum.不仅如此，他还在大英博物馆著名的图书阅览室里工作过。Sadly the library had moved from its original place into another building and the old reading room was gone.遗憾的是，这个图书馆已经从原来的地方搬到另一座大楼里去了，而原来的阅览室也没有了。But she was thrilled by so many wonderful treasures from different cultures displayed in the museum.但是她感到最为震惊的却是博物馆里展出的那么多来自不同文化的奇妙宝物。When she saw many visitors enjoying looking at the beautiful old Chinese pots and other objects on show, she felt very proud of her country.当萍玉看到那么多参观者用欣赏的目光注视着古老漂亮的中国陶瓷和其他展品时，心里充满了对祖国的自豪感。The next day Pingyu was leaving London for Windsor Castle.再过一天，萍玉就要离开伦敦去温莎城堡了。Perhaps I will see the Queen? she wondered as she fell asleep.她边睡觉边想：“也许我能见到女王呢？”5. 必修五Unit 3 FIRST IMPRESSIONS第一印象Spacemall: liqiang299AGreatAdventureSpaceStation.com太空邮件：liqiang299AGreatAdventureSpaceSation.com 15/11/3008 (Earthtime)(地球时间) Dear Mum and Dad, I still cannot believe that I am taking up this prize that I won last year.亲爱的爸爸妈妈：我现在仍然无法相信我是在接受去年获得的这个奖励。I have to remind myself constantly that I am really in AD 3008.我得不断提醒自己，我真的已经进入到公元3008年了。Worried about the journey, I was unsettled for the first few days. As a result, I suffered from “Time lag”.因为担心这次旅行，头几天我心里总是不踏实，结果我得了时间滞后症。This is similar to the “jet lag” you get from flying, but it seems you keep getting flashbacks from your previous time period.这就与你乘坐飞机会产生时差反应相似，所不同的是，在你的脑子里似乎会不断闪现以前的时光。So I was very nervous and uncertain at first.因此，我一开始就感到神经过敏和心神不定。However, my friend and guide, Wang Ping, was very understanding and gave me some green tablets which helped a lot.但是我的朋友兼导游王平很细心体贴，给了我几粒绿色药片，倒是挺起作用的。Well-known for their expertise, his parents company, called Future Tours, transported me safely into the future in a time capsule.他父母的公司叫做“未来之旅”，以其技术高超而闻名。他们把我装在一个时间舱里，平安地把我送入了未来。I can still remember the moment when the space stewardess called us all to the capsule and we climbed in through a small opening.我仍旧记得我们被太空服务员一起叫到时间舱，爬上去进入一个小门。The seats were comfortable and after a calming drink, we felt sleepy and closed our eyes.座位是很舒适的，喝了点镇静剂后，我们的眼睛就闭上了，感到昏昏欲睡似的。The capsule began swinging gently sideways as we lay relaxed and dreaming.时间舱在轻轻左右摇晃，我们放松地躺在那里做梦。A few minutes later, the journey was completed and we had arrived.几分钟以后，旅程结束，我们就到了。I was still on the earth but one thousand years in the future. What would I find?我仍然在地球上，但是进入到了未来的一千年。我们会看到什么呢？ At first my new surroundings were difficult to tolerate.一开始新的环境让我很难忍受。The air seemed thin, as though its combination of gases had little oxygen left.空气似乎很稀薄，好像在混合的气体中剩下的氧气很少。Hit by a lack of fresh air, my head ached.由于缺乏新鲜空气，我感到头痛。Just as I tried to make the necessary adjustment to this new situation, Wang Ping appeared.正当我想努力调整适应新环境时，王平出现了。Put on this mask, he advised. Itll make you feel much better.他告诉我，“把这个面罩戴上。它会使你感觉好得多。” He handed it to me and immediately hurried me through to a small room nearby for a rest.他把面罩递给我，敦促我马上走进附近的一个小房间，叫我休息。I felt better in no time.我立刻就感到舒服些了。Soon I was back on my feet again and following him to collect a hovering carriage driven by computer.很快，我就又一次恢复过来了，跟着他去领取了一台由电脑驱动的气垫车。These carriages float above the ground and by bending or pressing down in your seat, you can move swiftly.这些气垫车是在地面上方漂浮着的，只要在座位上把操纵杆打弯或压下，你就可以迅速地移动。Wang Ping fastened my safety belt and showed me how to use it.王平系紧了我的安全带，教我怎样使用它。Soon I could fly as fast as him.不久，我就可以飞得跟王平一样快了。However, I lost sight of Wang Ping when we reached what looked like a large market because of too many carriages flying by in all directions.可是，当我们到达一个看上去像大市场的地方时，由于太多车子朝四面八方飞奔，我看不见王平了。He was swept up into the centre of them.他被卷入到这群车队里去了。Just at that moment I had a time lag flashback and saw the area again as it had been in the year AD 2008.就在这个时候我得到一次“时间滞后”的闪回，这样我就再次看到了似乎是公元2008年的那个地区。I realized that I had been transported into the future of what was still my hometown!我这才懂得我被送到了未来，但却仍然在自己的家乡。Then I caught sight of Wang Ping again and flew after him.就在这个时候，我又见到了王平，于是又跟在他后面飞去。Arriving at a strange-looking house, he showed me into a large, bright clean room.到了一幢看上去很奇怪的房子里，他把我带到一个明亮而洁净的大房间。It had a green wall, a brown floor and soft lighting.墙是绿色的，地板是棕色的，灯光很柔和。Suddenly the wall moved - it was made of trees!突然墙壁移动了原来是树形成的！I found later that their leaves provided the room with much-needed oxygen.后来我才发现，就是这些树的叶子为这栋房屋提供了最急需的氧气。Then Wang Ping flashed a switch on a computer screen, and a table and some chairs rose from under the floor as if by magic.然后王平在电脑屏幕上的开关上闪了一下，于是一张桌子和几把椅子就像变魔术那样从地板下面升了起来。Why not sit down and eat a little? he said. “怎么不坐下来吃些东西呢？”他说道，You may find this difficult as it is your first time travel trip. “你第一次作这样的时间旅行，可能会感到有些困难。Just relax, since there is nothing planned on the timetable today.你可以好好休息一下。今天没有任何出行计划。Tomorrow youll be ready for some visits.明天你还要准备参观几个地方。” Having said this, he spread some food on the table, and produced a bed from the floor.说完这些，他把食物摆在桌子上，又从地板下取出一张床来。After he left, I had a brief meal and a hot bath.他离开后，我简单吃了饭，洗了个热水澡。Exhausted, I slid into bed and fell fast asleep.实在累坏了，我溜上床很快就睡着了。More news later from以后再谈吧！ your loving son,你的儿子Li Qiang李强6. 必修五Unit 3 I HAVE SEEN AMAZING THINGS我看到了奇妙的东西My first visit was to a space station considered the most modern in space.我首先参观的是一个太空站，这个站被认为是太空中最现代化的地方。Described as an enormous round plate, it spins slowly in space to imitate the pull of the earths gravity.太空站像一个巨大的圆盘，在太空中缓缓的旋转，以仿照出地球重心的引力。Inside was an exhibition of the most up-to-date inventions of the 31 st century.太空站里展出了31世纪一些最前沿的发明。A guide (G) showed us around along a moveable path.有个导游带领我们站在一条移动的运送带上，到各处参观。G: Good morning to all our visitors from 2008.导游：从2008年来访的朋友们，早上好！First were going to examine one of the latest forms of communication among our space citizens.首先，我们要查看一种我们太空居民使用的最新的通讯方式。No more typists working on a typewriter or computer!再也不需要打字员在打字机或电脑上工作了！No more postage or postcodes!再也不需要邮费和邮政编码了！Messages can now be sent using a thought pad.现在用一种“思想仪”就可以传递信息。You place the metal band over your head, clear your mind, press the sending button, think your message and the next instant its sent.你把金属带放在头上，整理思路，按下发送键，集中精神想着你要发送的信息，片刻功夫信息就发送出去了。Its stored on the thought pad of the receiver.这个信息会储存在接受者的“思想仪”里。Its quick, efficient and environmentally friendly.它快捷有效，而且环保。The only limitation is if the user does not think his or her message clearly, an unclear message may be sent.唯一的缺点是，如果使用者不能想清楚要传递的信息，发送出去的信息可能是模糊不清的。But we cannot blame the tools for the faults of the user, can
