[对应学生用书P85] Section Ⅰ Starting out & Understanding ideas [对应学生用书P85] CLICK FOR A FRIEND? How would you feel if moving to a new town meant① losing track of② your friends？[1]What if the only way of getting news from faraway friends was writing letters that took ages to be delivered? This was [2]how things worked not very long ago．Thanks to③ advances④ in technology，[3]how we make friends and communicate with them has changed significantly⑤. [1]本句为“What if...？”句式，意为“假若……怎么办？要是……会怎么样？”；其中that引导定语从句，修饰先行词letters。 [2]此处为how引导的表语从句，how在从句中作方式状语。 [3]此处为how引导的主语从句。 Nowadays, we can move around the world and still stay in touch with the people that we want to remain⑥ friends with.[4]Social media tools let us see what our friends are up to⑦ and maintain friendships. All you need is a wi-fi connection. [4]本句中and连接两个并列的非谓语动词see和maintain；其中what our friends are up to为what引导的宾语从句，what在从句中作宾语。 The digital⑧ age also enables⑨ us to find people who share our interests, such as collecting model cars or playing an unusual⑩ instrument⑪.[5]Whatever our hobbies, the Internet can connect us with ⑫ others who also enjoy doing them, even if they live on the other side of the world. [5]本句是主从复合句，其中Whatever our hobbies是“特殊疑问词＋-ever”引导的让步状语从句(省略了be动词)，主句中包含who引导的定语从句，修饰先行词others；even if 引导让步状语从句。 But when you “friend⑬” people online, does this mean that they really are your friends? It depends⑭. If people always exchange⑮ true personal information online, then yes, these friendships can be real and meaningful⑯.But we need to keep in mind⑰ that what we see on social media is often not the whole truth about a person. On social media sites, people tend to⑱ postB19 only positive updates that make them appear happy and friendly.But smiling photosB20 can hide real problems.Remember the saying：on the Internet, nobody knows you're a dog.A young person could be old；a woman could be a man；we could even be sharing our information with criminals㉑. But this doesn't mean that we should throw the baby out with the bathwater.[6]Although technology has changed the way we acquire friends, the meaning of friendship and our longing forB22 friends remain the same. As Aristotle said, no one would choose to live without friends, even if he had all other goods. [6]本句中although 引导让步状语从句，其中we acquire friends为省略了关系词that或in which的定语从句，修饰先行词the way。 ①mean v.产生……结果，意味着 mean doing sth 意味着做某事 ②lose track of 不了解……的情况，不了解……的动态 keep track of了解……的情况或动态 ③thanks to归功于……，多亏…… ④advance n.进步，进展vi.前进；进展 ⑤significantly adv.重大地，显著地 ⑥remain link-v.仍然是，保持不变 ⑦be up to 从事，忙于；胜任；该由……负责 ⑧digital adj.数字的，数码的 the digital age 数码时代 ⑨enable v.使可能，使发生 ⑩unusual adj.异常的，不平常的 ⑪instrument n.乐器 ⑫connect sb with...把某人同……联系起来 ⑬friend v.[熟词生义] (社交网站上)加……为好友 ⑭It depends.视情况而定。 ⑮exchange vt.交流；交换 ⑯meaningful adj.有意义的 ⑰keep...in mind 将……记在心中 ⑱tend to do sth 易于做某事 tend v.易于做某事，往往会发生某事 ⑲post v.公布；发布 ⑳smiling photos 面带微笑的照片 ㉑criminal n.罪犯 ㉒longing for...渴望…… longing n.渴望；热望 [文化采风] 1．On the Internet, nobody knows you're a dog.(在互联网上，没人知道你是一条狗。)这是一句互联网上的常用语，因作为The New Yorker(《纽约客》)1993年7月5日刊登的一则漫画的标题而流行。 2．throw the baby out with the bathwater(不分良莠一起抛弃)是一句俗语，指在泼洗澡水的时候连孩子一起泼掉了，喻指在摒弃不重要的东西的同时，将重要的东西也抛弃了。 一键交友？ 如果搬家到一个新的城镇意味着与你的朋友失去联系，那么你会有什么样的感受呢？如果写信是从远方的朋友那里获得消息的唯一途径，且信要很久才能送达又会怎么样呢？这是不久前朋友之间交流的方式。多亏了科技的进步，我们交友以及与他们交流的方式已经发生了巨大的变化。 现在，我们可以搬到世界各地，并仍与我们想维持朋友关系的人保持联系。社交媒体工具让我们了解朋友的最新状态，让我们维系友谊。你需要的只是连上无线网络。 数字时代还让我们可以找到兴趣相投的人，比如收集汽车模型或演奏某种罕见乐器。无论我们的爱好是什么，互联网总能把我们与那些喜爱做同样事情的人联系起来，即使那些人生活在世界的另一端。 但当你在网络上加他人为好友时，这是否意味着他们真的是你的朋友了呢？ 视情况而定。 如果人们总是在网上交换个人的真实信息，那么是的，这样的友谊可能是真实且有意义的。但我们需要记住，我们在社交媒体上看到的往往不是一个人的全部真相。 在社交媒体网站上，人们往往只会将正面的最新信息展现出来，让他们看起来快乐、友好。但是，微笑的照片可以掩盖真正的问题。记住这句话：在互联网上，没有人知道你是一条狗。年轻人可能实际年龄很大；女人可能是男人；我们甚至可能正在与罪犯分享自己的信息。 但这并不意味着我们要不分良莠一起抛弃。虽然科技改变了我们获得朋友的方式，但友谊的意义和我们对朋友的渴望仍然是一样的。正如亚里士多德所说的那样，没有人会选择没有朋友的生活，即使他拥有一切。 [对应学生用书P87] Ⅰ.重点词汇 核心单词 1．forever adv.永远 2．familiar adj.熟悉的 3．adventure n.历险(经历)，奇遇 4．click v.点击(鼠标) 5．deliver v.递送，传送 6．maintain v.保持，维持 7．digital adj.数字的，数码的 8．site n.网站 9．update n.最新消息 10．saying n.格言，谚语，警句 11．acquire v.获得，得到 12．goods n.商品 13．illustrate v.(举例)说明，阐明 14．diagram n.图解，示意图 拓展词汇 1．prefer v.更喜欢→preference n.偏爱；爱好 2．advance n.进步；进展→advanced adj.先进的，高级的 3．significantly adv.重大地；显著地→significant adj.重大的，显著的→significance n.重要；有意义 4．enable v.使可能；使发生→able adj.能够的；有能力的；有才干的→unable adj.不能的，不会的；无能力的 5．unusual adj.异常的；不平常的→usual adj.通常的→usually adv.通常地 6．tend v.易于做某事，往往会发生某事→tendency n.倾向，趋势 7．prove v.证明，证实→proof n.证明，证实，证据 Ⅱ.重点短语 1．lose track of 不了解……的情况，不了解……的动态 2．thanks to 归功于……，多亏了…… 3．move around the world 周游世界 4．stay in touch with 同……保持联系 5．be up to忙于某事 6．connect...with．..把……和……联系起来 7．keep in mind 记住 8．throw the baby out with the bathwater不分良莠一起抛弃 Ⅲ.重点句型 1．What if...？假若……怎么办？/要是……将会怎么样？ What if (如果……会怎么样)the only way of getting news from faraway friends was writing letters that took ages to be delivered? 2．whatever引导让步状语从句 Whatever our hobbies(不管我们有什么样的爱好), the Internet can connect us with others who also enjoy doing them, even if they live on the other side of the world. 3．what引导主语从句 But we need to keep in mind that what we see on social media(我们在社交媒体上看到的) is often not the whole truth about a person.
