[分析]　这是一个主从复合句，句子主干为These digital identities are a key part of... 。how引导宾语从句；known as avatars为动词-ed形式短语作定语。 [翻译]　这些数字身份被称作“虚拟形象”，是人们利用互联网进行交流和表达自己的关键部分。 2．When people started creating their own avatars，they discovered that they were going to have the power to create new identities that did not look or act like their real selves at all. [分析]　这是一个主从复合句，句子主干为they discovered... 。第一个that引导动词discovered后的宾语从句，第二个that引导identities后的定语从句；when引导时间状语从句。 [翻译]　当人们开始创设自己的虚拟形象时，他们发现自己将有能力创设新的身份，这种身份的外观和行为完全不像他们真实的自己。 3．Most people create avatars that have similar features to their personalities and that look more or less like them and act like them. [分析]　这是一个主从复合句，句子主干为Most people create avatars 。句中两个that均引导定语从句，修饰同一个先行词avatars。 [翻译]　大多数人创设的虚拟形象与他们的个性有着相似的特征，看起来或多或少像他们，在行为上也像他们。 4．They also experiment with things like different hairstyles—which says a lot，perhaps，about what they want to look like. [分析]　这是一个主从复合句，句子主干为They also experiment... 。which引导非限制性定语从句，破折号在本句相当于逗号；what引导宾语从句，作介词about的宾语。 [翻译]　人们还进行尝试，例如换不同的发型，这可能从很大程度上透露了他们希望自己看起来是什么样子。 Ⅱ.佳句仿写 1．[教材佳句]　However，nearly all avatars are tall，young and nice-looking，so people obviously make their avatars look better than they do in real life.(外貌描写；比较结构) [学后仿写]　除了个子高、年纪小之外，他还长得特别好看，五官比许多名人都要好。 学生用书第8页 Besides being tall and young ，he was exceptionally nice-looking，with features better than those of many celebrities. 2．[教材佳句]　The avatars in online worlds can talk，walk and fly around，meet people，go shopping and attend classes.(动作链描写) [学后仿写]　 虚拟人开始发光、闪烁，并转变成一个更强大的形态。 The avatar started to glow，shine，and then turn into a more powerful form． Ⅲ.课文开发(黑体部分和填空内容均为课表词汇或课文重要表达) Nowadays，information technology has changed the way we communicate.Through blogs，social media，and online games，people can 1.create their own avatars (创造自己的虚拟形象) and new personalities.Many users have more than one avatar to explore different sides of themselves.It's an exciting way to 2.experiment with things (尝试一些事情)you might not try in real life.Digital identity gives people the chance to 3.be viewed in a more positive light (用更积极的眼光看待自己).But it can also 4.cause a few concerns (引起一些担心).While a fancy online persona is appealing，it's important to stay sensible and remember who you are in the real world.Some people cheat by pretending to be someone they're not.This can lead to trust issues.There is a variety of apps and platforms offering 5.a selection of ready-made images (精选的现成图像) and avatars.Users can pick a type that they feel represents them，or create something entirely unique.Obviously，this flexibility allows creativity but also brings up questions and doubts.In the digital world，finding a balance between reality and virtual is key. ……………………………………………………………………………◎ ①say熟词生义 vt.表明(某人的性格或某物的特质)是……。say a lot about...充分表明了…… ②personality/ˌpɜːsə'næləti/n.个性，性格 ③2D(2-dimensional) adj.二维的 ④appear vi.出现，首次使用 ⑤role-playing computer games 角色扮演电脑游戏 ⑥a wide variety of...种类繁多的…… variety/və'raɪəti/n.多样化，变化 ⑦web chats 网络聊天 ⑧self n．(自己的)通常的行为方式，本来面目，惯常心态 one's real self 某人真实的自我 ⑨dress...in...给……穿…… ⑩the opposite sex异性 opposite adj.相反的；对立的 sex/seks/n.性别 sensible/'sensəbəl/adj.朴素实用的；明智的，合理的 good-looking adj.漂亮的，好看的 creativity/ˌkriːeɪ'tɪvəti/n.创造力；独创性 room for creativity 创造空间 blog/blɒɡ/n.博客；网络日志 vi.写博客 blog posts博文；博客帖子 blogger n．博客作者；博主 microblog n．微博 more or less 几乎，差不多；或多或少 obviously/'ɒbviəsli/adv.显而易见地，明显地 obvious adj.明显的，显然的  experiment/ɪk'sperɪmənt/vi.&vt.做实验，进行试验n.实验 hairstyle/'heəstaɪl/n.发型，发式 nowadays/'naʊədeɪz/adv.现今，现时 selection/sɪ'lekʃən/n.供选择的同类物品；选择 a wide selection of...多种多样的……可供选择 ready-made adj.已做好的，现成的 type in将(文字等)输入，键入type/taɪp/vt.&vi.打；打字n.类型，种类 attend classes上课 concern/kən'sɜːn/n.担忧，忧虑vt.与……有关；使担心 risk n．会带来风险的事物 cheat/tʃiːt/vt.欺骗；欺诈 view/vjuː/vt.看，把……视为 view...in a positive light从积极的角度来看待…… light熟词生义 n．见解，角度，眼光 look forward to(高兴地)盼望，期待(to为介词) ◎…………………………………………………………………………… AVATARS The avatar you choose says① a lot about you.The article will help you understand your choice of avatars better. When you are online，you can be anyone or anything.You can create your own image and a new personality②.These digital identities，known as avatars，are a key part of how people use the Internet to communicate and express themselves. The first simple 2D③ avatars appeared④ in role-playing computer games⑤ in the 1980s.Yet，very few people knew that future avatars would have such a wide variety of⑥ forms and uses.By the late 1990s，they had been used in web chats⑦.[1] [1]该句中使用了过去完成时的被动语态。此处they指代前文提到的avatars，与use是动宾关系，故用被动语态。根据时间状语By the late 1990s可知，本句谓语应用过去完成时。 学生用书第9页 When people started creating their own avatars，they discovered that they were going to have the power to create new identities that did not look or act like their real selves⑧ at all.They could dress their avatars in⑨ fancy clothes，or they could try being someone of the opposite sex⑩，and call themselves “Andy” instead of “Anna”！ When Internet users realised that their avatars would be seen [2] by many people，not just their friends，they started having more than one avatar：a sensible one for work；a friendly，good-looking one for meeting people；and a silly one for having fun.Avatars let you express yourself and give you lots of room for creativity. [2]此处使用了过去将来时的被动语态。see与their avatars之间为动宾关系，故用被动语态；根据realised可知，see表示的动作发生在过去，故用过去将来时。 Of course，the avatar you choose says a lot about your personality.If your blog avatar is a picture of a cute cat，your message is “I like relaxing and having fun”．Well-known cartoon characters or laughing monkeys say “I'm a really funny person”．Most people create avatars that have similar features to their personalities and that look more or less like them and act like them.However，nearly all avatars are tall，young and nice-looking，so people obviously make their avatars look better than they do in real life[3].They also experiment with things like different hairstyles—which says a lot，perhaps，about what they want to look like. [3]此处they do是比较句型后的替代省略结构，相当于they look/appear，即“看起来的样子”。 Nowadays，avatars are everywhere.In most web chats，people choose an avatar from a selection of ready-made images，or create their own images.You can also use avatars that move around and talk when you type in your message[4].The avatars in online worlds can talk，walk and fly around，meet people，go shopping and attend classes. [4]本句为主从复合句。“when you type in your message”为when引导的时间状语从句。“that move around and talk”是that引导的定语从句，修饰先行词avatars。 学生用书第10页 The use of avatars has also caused a few concerns.Some users worry that they are spending so much time in virtual worlds that they are becoming afraid of meeting people in the real world [5].The use of several avatars can also be a risk，as people can use avatars to cheat others online.However，other users view avatars in a more positive light.They look forward toa time when their avatar will act like a real person and travel around bigger，more exciting virtual worlds [6]. [5]“that they are spending...real world”为that引导的宾语从句，作动词worry的宾语；在宾语从句中包含“so...that...”结构，此结构中的that引导结果状语从句。 [6]“when their...worlds”为when引导的定语从句，修饰先行词a time。 ……………………………………………………………………………◎ 虚拟形象 你选择的虚拟形象能透露出你的很多信息。这篇文章将帮助你更好地理解关于虚拟形象的选择。 当你上网时，你可以是任何人或任何事物。你可以创设自己的形象，并且拥有新的个性。这些数字身份被称作“虚拟形象”，是人们利用互联网进行交流和表达自己的关键部分。 简单的二维虚拟形象最早出现在20世纪80年代的角色扮演电脑游戏中。然而，很少有人知道未来的虚拟形象会有如此广泛的形式和用途。到20世纪90年代末，虚拟形象就已经用于网络聊天中了。 当人们开始创设自己的虚拟形象时，他们发现自己将有能力创设新的身份，这种身份的外观和行为完全不像他们真实的自己。他们可以给自己的虚拟形象穿上精致的衣服，或者尝试换个性别，并给自己取名为“安迪”，而不是“安娜”！当互联网用户意识到很多人会看到他们的虚拟形象，而不仅仅是他们的朋友时，他们开始使用不止一个虚拟形象：一个朴素实用的虚拟形象用于工作；一个友好的、漂亮的虚拟形象用于交友；一个傻乎乎的虚拟形象用于取乐。虚拟形象让你可以表达自己，还给你很多创造空间。 当然，你所选择的虚拟形象会在很大程度上显露你的个性。如果你的博客头像是一只可爱的猫，你传递的信息是“我喜欢放松和玩乐”。著名的卡通角色或大笑的猴子表示“我是个很有趣的人”。大多数人创设的虚拟形象与他们的个性有着相似的特征，看起来或多或少像他们，在行为上也像他们。然而，几乎所有的虚拟形象都个头高挑、年轻、面容姣好，所以人们显然想让他们的虚拟形象看起来比现实生活中更好。人们还进行尝试，例如换不同的发型，这可能从很大程度上透露了他们希望自己看起来是什么样子。 现在，虚拟形象无处不在。在大多数网络聊天中，人们都是从现成的图片中选择一个作为虚拟形象，或者创建自己的图片。你还可以使用在输入信息时能够活动或说话的虚拟形象。网络世界中的虚拟形象可以交谈、行走、四处飞行，还可以结识他人、购物和上课。 学生用书第11页 虚拟形象的使用也引起了一些担忧。一些用户担心他们在虚拟世界中花费了太多时间，以至于变得害怕在现实世界中与人见面。使用多个虚拟形象也可能会带来风险，因为有人可能会在网上使用虚拟形象来欺骗他人。然而，其他用户则从更为积极的角度看待虚拟形象。他们期待着有朝一日，自己的虚拟形象会像真人一样去环游更广阔、更精彩的虚拟世界。 Ⅰ.阅读单词——识记 1．different racial types 　　　　 不同的人种 2．personal identity 个人身份 3．virtual reality 虚拟现实 4．sensible advice 明智的建议 5．start a blog 开始写博客 6．change her hairstyle 改变她的发型 Ⅱ.核心单词——练通 1．create an energetic image 　 塑造一个充满活力的形象 2．sex discrimination 性别歧视 3．cheat in the exam 考试作弊 4．scientific experiments 科学实验 5．make a selection 做出选择 6．.be concerned about 对……感到担忧 Ⅲ.拓展词汇——用活 1．trick the public欺骗公众 →a tricky decision 棘手的决定 2．add more variety 增加更多的变化 →various types 各种类型 →vary in size大小各不同 3．create opportunities 创造机会 →show creativity 展示创造力 →creative thinking 创造性思维 4．identify a problem 识别问题 →identity cards身份证 5．obviously different 显然不同 →an obvious mistake 明显的错误 6．cause a few concerns 引起一些担忧 →everyone concerned 所有有关人员 Ⅳ.重点短语——再现 第一组　汉译英 1．a variety of 　　　　 各种各样的 2．not...at all 一点也不 3．more or less 几乎，差不多；或多或少 4．look forward to (高兴地)盼望，期待 5．by the late 1990s 到二十世纪九十年代末为止 第二组　英译汉 6．attend classes　　　　　　 上课 7．type in 将(文字等)输入，键入 8．view...in a positive light 从积极的角度来看待…… 9．a selection of ready-made images 精选的现成图像 10．give you lots of room for creativity 给你很大的创新空间 Ⅴ.典型句式——默背 1．These digital identities，known as avatars (被称作“虚拟形象”。动词-ed形式短语作定语)，are a key part of how people use the Internet to communicate and express themselves. 2．Some users worry that they are spending so much time (花费那么多时间)in virtual worlds that they are becoming afraid of meeting people (以至于变得害怕见人) in the real world. 3．They also experiment with things like different hairstyles—which says a lot，perhaps，about what they want to look like (他们想要看起来像什么。what引导宾语从句). 4．Most people create avatars that have similar features to their personalities and that look more or less like them (看起来或多或少像他们。定语从句)and act like them. 学生用书第12页 Ⅰ.核心词汇练全 trick vt.欺骗，诱骗，哄骗 (tricky adj.难对付的；狡猾的，诡计多端的) (1)trick sb into doing sth　 诱骗/哄骗某人做某事 trick sb out of sth 骗走某人某物，诈骗某人某物 (2)trick n. 诡计，花招，骗局；技巧，诀窍 play a trick/tricks on sb 捉弄某人，对某人恶作剧 do the trick 奏效　　 (1) Some people are good at tricking (trick) others into giving them personal information online.
