(下定义) [学后仿写]　文化庆祝活动通常是指庆祝某一特定民族或地方的传统的活动。 A cultural celebration usually refers to an event where the traditions of a particular people or place are celebrated. 2．[教材佳句]　For example，the Oscar-winning film Babel is based on the concept of “Six Degrees of Separation”.

Good interpersonal connections can relieve psychological pressure and promote mental health. But for bad interpersonal connections，it is easy to let people have psychological barriers. 2．Why did Milgram and Columbia University both label their experiments “small-world”？(Creative Thinking创造性思维) Because they chose a random sample of people and asked them to send packages to a stranger who only knew his name，job and general location. ……………………………………………………………………………◎ ①in fact 事实上，实际上 ②refer to参考，查阅；提到，提及；指的是 ③theory/'θɪəri/n.学说，理论 ④chain/tʃeɪn/n.一连串，一系列；链子，链条 a chain of一系列，一连串(人或事) ⑤no more than只是；仅仅；不超过 not more than不超过；至多；不比……更…… ⑥network/'netwɜːk/n.人际关系网，联络网；网络，网状系统 ⑦impression/ɪm'preʃən/n.印象，感想 impress vt.& vi.使钦佩； 给……留下深刻的好印象 impressive adj.给人印象深刻的，令人钦佩的 ⑧in the 1950s为“in the＋年代的复数”，表示“在……世纪……年代”。 ⑨mathematically adv.算术地，数学上地 ⑩sociologist/ˌsəʊsi'ɒlədʒist/n.社会学家 random/'rændəm/adj.随机的，随意的 at random随便地；任意地 randomly adv.随机地；任意地 in the middle of在……中间 location n．地点，位置；外景拍摄地 locate vt.找出……的准确位置 be located in 位于；坐落于 personally adv.就个人而言；亲自 person n．人 in person 亲自 personal adj.个人的，私人的 deliver vt.& vi.传送，递送 delivery n．递送；传达 amazingly adv.令人惊讶地；惊奇地 amaze vt.使惊奇，使惊愕 amazed adj.惊奇的，惊讶的 amazing adj.令人大为惊奇的 amazement n．惊诧，惊奇 release/rɪ'liːs/vt.& n．发表，发布；释放 bimonthly/baɪ'mʌnθli/adj.两月一次的；一月两次的 phrase/freɪz/n.成语，习语；警句 recreate vt.再创造；再现 confirm vt.& vi.证实，证明 analyse vt.分析(等于analyze) analysis n．分析，分析结果 ◎…………………………………………………………………………… HOW CLOSELY CONNECTED ARE WE？ Research shows the average person only has regular communication with between seven and fifteen people，and that most of our communication is in fact① with five to ten people who are closest to us.[1]However，perhaps we are closer to the rest of the world than we think.“Six Degrees of Separation”refers to② the theory③ that any person on Earth can be connected to any other person through a chain④ of no more than⑤ five other people. [1]本句为主从复合句。句中“the average person...people”为省略了引导词that的宾语从句；and后的that也引导宾语从句；who引导定语从句，修饰先行词five to ten people。 The concept was first talked about as long ago as the 1920s.The Hungarian author Frigyes Karinthy published a book called Everything Is Different in 1929，in which he introduced the idea of friendship networks⑥ and his ideas influenced many of our early impressions⑦ of social networks.[2] [2]本句为主从复合句。“called Everything Is Different”为动词-ed形式短语作后置定语；in which引导非限制性定语从句，修饰先行词a book。 In the 1950s⑧，an attempt was made by two scientists to prove the theory mathematically⑨；but after twenty years，they still had not had any success.In 1967，an American sociologist⑩ called Stanley Milgram tried using a new method to test the theory，which he called the “small-world problem”．He chose a random sample of people in the middle of America and asked them to send packages to a stranger in the state of Massachusetts.The people sending the packages only knew the name，job and general location of the stranger.Milgram told them to send the package to a person they knew personally who they thought might know the target stranger.Once the 学生用书第8页 parcel had been received by this person，he/she would send the parcel onto a contact of theirs until the parcel could be personally delivered to the correct person.Amazingly，it only took between five and seven people to get the parcels delivered，and once released [3]，the results were published in the bimonthly magazine Psychology Today.It was this research that inspired the phrase “Six Degrees of Separation”．[4] [3]句中it作形式主语，动词不定式短语“to get the parcels delivered”作真正的主语；once released为状语从句的省略形式。 [4]本句为强调句。其结构为“It is/was＋被强调部分＋that/who...”。 In the last few decades，the theory and the phrase have appeared again.Its name was used as the title of a play and then a film.Then，more films and TV programmes based on the concept were made and broadcast.For example，the Oscar-winning film Babel is based on the concept of “Six Degrees of Separation”．The lives of all the characters were closely connected，although they did not know each other and lived thousands of miles apart.The television series Lost also explored the idea of “Six Degrees of Separation”，as almost all the characters had randomly met each other，or had met someone the other characters knew，before they were all in the same plane crash.In the mid-1990s，two college students in the United States invented a game.The idea of the game was to link any actor to Kevin Bacon，a famous American actor and musician，through no more than six links.Soon the game was being played in universities across the United States. In 2001，Columbia University tried to recreate Milgram's experiment on the Internet.This became known as the “Columbia Small-world Project”．The experiment involved 24，163 email chains with 18 target people in 13 different countries.[5]The results confirmed that the average number of links in the chain was six. [5]句中“with 18 target people in 13 different countries”为“with＋宾语＋宾语补足语”的复合结构。 Most recently，an experiment in 2011 at the University of Milan analysed the relationship between 721 million social media users and found that 92 percent were connected by only four stages，or five degrees of separation. So，think about it for a minute：How might you be connected to the driver of the bus you regularly take or the person who delivers your parcels？ 学生用书第9页 ……………………………………………………………………………◎ 我们之间的联系有多紧密？ 研究表明，普通人只与7至15个人经常保持联系，而且其中大部分的交流实际上只发生在5到10个和我们最亲近的人身上。不过，也许我们与世界上其他人的联系比想象中的更紧密。“六度分隔”理论说的是地球上任何人都可通过不超过另外五个人的联结，与一个陌生人联系起来。 这个概念早在20世纪20年代就被提出。匈牙利作家弗里吉斯·考林蒂在1929年出版了《一切皆不同》一书，书中介绍了朋友关系网的概念，许多早期关于社交网络的构想都受到了他的思想的影响。 20世纪50年代，两位科学家试图用数学方法证明该理论，但20年过去了，他们仍未成功。1967年，美国社会学家斯坦利·米尔格兰姆试图用新的方法来验证这一理论，他称之为“小世界问题”。他在美国中部随机挑选了一部分人作为样本，让他们给马萨诸塞州的一位陌生人寄包裹。这些寄送包裹的人只知道这位陌生人的姓名、工作和大致的位置。米尔格兰姆告诉这些人先把包裹寄给认为有可能认识目标收件人的熟人。一旦此人收到包裹，他或她就会将包裹再发给认识的人，直到该包裹被送到目标收件人手中。令人惊讶的是，只需要5至7个人就能把包裹送到。研究结果一经公布，便被发表在双月刊《今日心理学》上。正是这项研究启发了“六度分隔”这一说法。 在过去的几十年里，这一理论和说法又再次出现。它的名字被用作戏剧标题和电影名称。随后，更多基于这一理论的影视节目相继被拍摄、播出。例如，奥斯卡获奖影片《通天塔》就是基于“六度分隔”这一概念。影片中所有人物彼此不认识、相隔千里，但他们的生活都是紧密相连的。电视连续剧《迷失》也探讨了“六度分隔”的理论，剧中失事飞机上几乎所有人物此前都曾偶遇，或曾遇见其他人物认识的人。20世纪90年代中期，美国两名大学生发明了一款游戏。这款游戏的玩法是用不超过六个联结将任意一个演员与美国著名演员、音乐家凯文·贝肯联系起来。这款游戏很快在美国的大学里流行起来。 2001年，哥伦比亚大学尝试在互联网上重现米尔格兰姆的实验，该实验被称为“哥伦比亚小世界项目”。这项实验涉及24 163个电子邮件链接，覆盖了来自13个不同国家的18个目标人物。实验结果证实，联络串上的连接平均数量是6个。 最新的是2011年米兰大学的一项实验，该实验分析了7.21亿社交媒体用户之间的关系，发现92%的用户只需通过四个阶段(即五度分隔)，就可建立联系。 所以，思考一下这个问题：你与你经常乘坐的公交车司机或给你送包裹的人可能存在怎样的联系？ ◎阅读单词——识记 1．a bicycle chain　　　　　 自行车链条 2．a network of friends 朋友网 3．a memorable phrase 易记的警句 4．a famous sociologist 著名社会学家 ◎核心单词——练通 1．a bimonthly magazine 一本双月刊杂志 2. release a prisoner 释放囚犯 3．the theory and practice of language teaching 语言教学理论与实践 ◎拓展单词——用活 1．intervention n．干涉，干预 →intervene vi.干扰；介入 2．disagreement n．意见不合，分歧，争论 →disagree vi. 不同意 3．encouragement n．鼓励，鼓舞；起激励作用的事物 →encourage vt.鼓励；怂恿；激励；支持 4．envy n．羡慕，忌妒vt. 羡慕，妒忌 →envious adj.羡慕的；忌妒的 5．disturb vt.干扰，打扰，使中断 →disturbing adj.令人不安的，引起烦恼的 →disturbed adj.烦恼的；心神不安的 →disturbance n．干扰；骚动；妨碍 6．apologise vi.道歉，谢罪 →apology n．道歉，谢罪 7．theory n．学说，理论 →theoretical adj. 理论上的 学生用书第10页 8．impression n．印象，感想 →impress vt.使钦佩；给……留下深刻的好印象 →impressive adj.令人敬佩的 9．random adj.随机的，随意的 →randomly adv.随机地，任意地 1．规律：动词后跟-ive变成形容词 impress vt.使钦佩；给……留下深刻的好印象＋-ive→impressive adj.令人敬佩的 例如：creative adj.有创造力的 attractive adj.吸引人的 2．规律：动词后跟-ment变成名词 disagree vi.不同意＋-ment→disagreement n．意见不合，分歧，争论 例如：encouragement n．鼓励，鼓舞；起激励作用的事物 appointment n．预约，约定；任命 ◎重点短语——再现 第一组　汉译英 1．事实上，实际上　　　　　　　 in fact 2．闲逛；挂出 hang out 3．与……相处融洽；……进展顺利 get on well with... 4．处理；涉及 deal with 5．代替；而不是…… instead of 6．根据；以……为基础；建立在……基础上 be based on 第二组　英译汉 7．come up　　　　　　 发生；升起；发芽；被提出 8．sort out 挑选出；分类 9．go over to 朝……走去 10．refer to 参考，查阅；提到，提及；指的是 11．a chain of 一系列，一连串(人或事) 12．no more than 只是；仅仅；不超过 13．the number of... ……的数目 ◎典型句式——默背 1．句型公式　状语从句的省略 教材原句　...and once released(一经公布)，the results were published in the bimonthly magazine Psychology Today. 2．句型公式　强调句型 教材原句　It was this research that(正是这项研究) inspired the phrase “Six Degrees of Separation”． 3．句型公式　with复合结构 教材原句　The experiment involved 24，163 email chains with 18 target people in 13 different countries(覆盖了来自13个不同国家的18个目标人物).
