[分析]　这是一个并列复合句，连接词为and。前面分句是简单句。and后边分句是主从复合句，该分句 学生用书第23页 主干为you can never be 100 percent sure 。that引导名词性从句，who引导宾语从句，作介词about的宾语。 [翻译]　友谊建立在信任的基础上，通过线上交流，你永远不能百分之百地确信与你交谈的人是否以诚相待。 2．Because of this，going online can be particularly dangerous for people who are easily influenced or too trusting. [分析]　这是一个主从复合句，句子主干为going online can be particularly dangerous ，主语是动词-ing形式短语going online。who引导定语从句，修饰people。 [翻译]　因此，对于那些容易受影响或太过轻信的人来说，上网会尤其危险。 Ⅱ.佳句仿写 1．[教材佳句]　According to a parenting expert，Denise Daniels，communicating through a screen makes it more difficult for children to concentrate or show kindness to others.(应用文写作中转述观点；make复合结构＋it形式宾语结构) [佳句仿写]　根据一些研究，人们花在朋友身上的时间更少，因为他们在网上，这使得朋友在现实生活中更难联系。 According to some studies ，people spend less time with friends because they are online，which can make it more difficult for friends to connect in real life． 2．[教材佳句]　It is these skills that enable us to develop lifelong friendships.(强调句型强调主语) [佳句仿写]　研究表明，那些只在网上聊天的朋友往往不会保持亲密。 Studies show that it is the friends who only chat online that/who often do not stay close. 3．[教材佳句]　As Eileen Kennedy-Moore，an authority on the subject，points out，online friends“fill holes real-life friends can't”．(引用名人名言支持观点) [佳句仿写]　正如研究人员指出的那样，许多人在网上找到志同道合的朋友。 Many people，as researchers point out , find friends online who share their interests. 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) Many people say that the Internet is a great way to make friends，but some believe there is no replacement for face-to-face contact.Making friends 1.on the basis of online chats (在网上聊天基础上) can be particularly dangerous，especially for young people.Parents often worry about their children's online activities and 2.are concerned with who their kids are talking to (关心孩子在跟谁说话).They want them to 3.maintain healthy relationships (保持健康的关系)with people they meet in real life.Some studies show that too much time online can 4.make it more difficult for children to concentrate/focus on (使得孩子们更难集中精力于) schoolwork.In addition，there is content online that is not always suitable for children. However，many others believe the Internet 5.makes communication much more convenient (使得交流更为便捷) for people today.It is easier to stay in touch with friends from different places.You can 6.give a response to a message quickly (快速对一个信息作出回复).Many people point out the benefits of using social media.Some even say it offers a very thought-provoking argument for staying connected.It's also a creative way to express yourself.Most people enjoy the content they share and 7.find it rewarding (发现其内容有意义).In fact，a high percent of young people say they can't imagine life without it. 学生用书第24页 ……………………………………………………………………………◎ ①be no replacement for不能替代 replacement/rɪ'pleɪsmənt/n.替换，更换 replace/rɪ'pleɪs/vt.取代；接替 ②face-to-face contact 面对面的接触 contact/'kɒntækt/n.&vt.联络，联系 ③real-life adj.真实的，实际发生的，现实生活中的(仅用于名词前) ④hug/hʌɡ/n.& vt.拥抱；紧抱 ⑤parenting expert 育儿专家 parenting n．养育，抚养，教养 good/poor parenting 教养有方/无方 ⑥concentrate/'kɒnsəntreɪt/vi.专注，专心；集中注意力 ⑦show kindness to sb 对某人表示善意 ⑧social skills社交技能 ⑨develop lifelong friendship发展终生的友谊 lifelong/'laɪflɒ/adj.终身的 ⑩but 熟词生义 prep.除了 be concerned with关心…… follower n．(微博上某人的)关注者；拥护者；效仿者 the number of...……的数量“the number of＋可数名词的复数形式”意为“……的数目”，作主语时，谓语动词用单数形式。 compare to...与……相比(to为介词) compare vt.比较，对比 long-term adj.长期的，长远的，长期有效的 rewarding/rɪ'wɔːdɪ/adj.有益的；有意义的 in addition除此之外 content/'kɒntent/n.内容 social media 社交媒体 shallow/'ʃæləʊ/adj.肤浅的，浅薄的 trivial/'trɪviəl/adj.没有什么价值的；微不足道的 not necessarily不一定 be built on the basis of...建立在……的基础上　 basis/'beɪsɪs/n.基础；基点 be 100 percent sure that...百分之百地确信…… percent/pə'sent/n.百分比；百分数 be honest about...对……诚实 go online上网 particularly adv.尤其，特别 trusting/'trʌstɪ/adj.轻信的，轻易信赖别人的 in one's opinion在某人看来(相当于in one's view) opinion/ə'pɪnjən/n.意见；看法；主张 focus on 关注focus /'fəʊkəs/vi.&vt.集中(注意力)n.焦点 way to do sth做某事的方法(＝way of doing sth) maintain /meɪn'teɪn/vt.保持；维持 ◎…………………………………………………………………………… The Internet Harms Friendships While the Internet can bring people closer together [1]，it can also harm friendships. Firstly，talking online [2] is no replacement for① face-to-face contact②—images really cannot replace a real-life③ smile or hug④.According to a parenting expert⑤，Denise Daniels，communicating through a screen makes it more difficult for children to concentrate⑥ or show kindness to⑦ others [3].As we know [4]，important social skills⑧ are developed through direct contact with other people.It is these skills that enable us to develop lifelong friendships⑨.[5] [1]While引导让步状语从句，While意为“尽管；虽然”。 [2]动词-ing形式短语作主语，谓语动词用单数形式。 [3]communicating through a screen为动词-ing形式短语作主语。makes it...to others属于“make it＋形容词/名词＋ for sb to do sth”结构，it为形式宾语，动词不定式短语to concentrate or show kindness to others是真正的宾语。 [4]As引导非限制性定语从句，As指代整个主句的内容。As we know意为“众所周知”。 [5]本句为强调句，强调主语these skills。 Secondly，the Internet can make people self-centred—not thinking of anyone or anything but⑩ themselves.For example，instead of having proper conversations with their friends，some people are only concerned with their online popularity—How many “likes” did I get？How many followers do I have？—though we know that the number of “likes” or followers cannot compare to having long-term and rewarding friendships [6].In addition，a lot of 学生用书第25页 the content posted on social media [7] is shallow or trivial.Posts about funny cat images do not necessarily help form meaningful relationships. [6]该句的主干是“some people are only concerned with their online popularity”。破折号之间的两个疑问句是对前面内容的解释和说明。though we know...rewarding friendships是though引导的让步状语从句，其中含有一个that引导的宾语从句，作动词know的宾语。 [7]动词-ed形式短语作后置定语，修饰名词content。 Thirdly，online relationships may not be what they appear to be [8].Friendships are built on the basis of trust，and with online communication you can never be 100 percent sure that the people you are chatting to are being honest about who they are.Because of this，going online can be particularly dangerous for people who are easily influenced or too trusting. [8]what在此处引导表语从句，what在从句中作表语。 In my opinion，friends should focus more on face-to-face communication，and less on online communication.This is the best way to maintain healthy relationships. ……………………………………………………………………………◎ 互联网对友谊有害 虽然互联网可以让人们更亲近，但它也会损害友谊。 首先，网上聊天不能代替面对面的接触——图片确实无法代替现实生活中的微笑或拥抱。根据育儿专家丹尼斯·丹尼尔斯的说法，通过屏幕交流会使儿童更难集中注意力或对他人表示善意。众所周知，重要的社交技能是通过直接与他人接触培养的。正是这些技能使我们能够发展终生的友谊。 其次，互联网使人们以自我为中心，即不去想除自己之外的任何人或任何事。例如，一些人不再和朋友好好地交谈了，他们只关心自己网上的人气——我得了多少个“赞”？多少人关注了我？——尽管我们知道有多少个“赞”或关注者无法与拥有长期和有益的友谊相比。此外，很多发布在社交媒体上的内容都很肤浅或琐碎。(在网上)发布搞笑猫咪的图片并不一定会帮助建立有意义的关系。 第三，网络关系可能并不是它们看起来的样子。友谊建立在信任的基础上，通过线上交流，你永远不能百分之百地确信与你交谈的人是否以诚相待。因此，对于那些容易受影响或太过轻信的人来说，上网会尤其危险。 在我看来，朋友们应该多关注面对面的交流，少进行线上交流。这是保持健康关系的最佳方式。 学生用书第26页 ……………………………………………………………………………◎ ①in many ways 在很多方面 ②stay in touch with...与……保持联系 ③smartphone /'smɑːtfəʊn/n.智能手机　 ④tablet/'tæblɪt/n.平板电脑；药片；碑，牌 ⑤be in contact 接触；联络 ⑥on the move 在行进中，在移动中 ⑦limiting/'lɪmɪtɪ/adj.局限的，限制性的 ⑧brief/briːf/adj.简洁的，简明的 ⑨a response to...对……的回应 response/rɪ'spɒns/n.反应；回答，答复 ⑩emoji/ɪ'məʊdʒi/n.表情符号 creative /kri'eɪtɪv/adj.创造性的 click/klɪk/n.(对计算机鼠标的)点击，单击 immediately adv.立即，马上，即刻 provide useful suggestions提供有用的建议 care for照顾，照料(病、老、幼者等)；深深地爱，非常喜欢 thought-provoking adj.发人深省的，令人深思的 point out指出 benefit/'benɪfɪt/n.益处，好处 beneficial /ˌbenɪfɪʃl/adj.有利的，有裨益的，有用的 authority/ɔː'θɒrəti/n.权威人士；专家 ◎…………………………………………………………………………… The Internet Helps Friendships The Internet can help develop friendships in many ways①. Firstly，the Internet makes communication much more convenient.You can stay in touch with② friends no matter where you are or what you are doing[1].Using a smartphone③，a tablet ④ or a computer[2]，you can be in contact⑤ at home and also when you are on the move⑥. [1]or为并列连词，连接两个“no matter＋特殊疑问词”引导的让步状语从句，what you are doing前省略了no matter。 [2]动词-ing形式短语作状语。 Secondly，the Internet has also made communication more fun.Traditional ways of communicating，like letters and phone calls，can be limiting⑦ and take time.However，you can share photos，videos，news stories and websites with your friends online.You can give a brief⑧ response to⑨ a message with an emoji⑩ or a picture.There are so many online tools you can use to be creative [3]! [3]you can use to be creative是省略了关系词that/which的定语从句，修饰先行词tools。 Thirdly，online communication can actually bring people closer to each other.Nowadays，your friends are just a click away.Whenever someone needs help[4]，friends from all over the world can immediately provide useful suggestions or information.This makes friends feel loved and cared for.To me，this is a very thought-provoking argument，as it points out the benefits of online friendships [5].As Eileen Kennedy-Moore，an authority on the subject，points out，online friends“fill holes real-life friends can't”．[6] [4]Whenever引导让步状语从句，相当于No matter when。 [5]此处为as引导的原因状语从句，as意为“因为，由于”。 [6]As在此引导非限制性定语从句，意为“正如”。real-life friends can't为省略了关系词的定语从句，修饰先行词holes，can't后省略了动词fill。 Finally，I believe the Internet brings people closer together and makes communication with friends more convenient and interesting. 学生用书第27页 ……………………………………………………………………………◎ 互联网对友谊有益 互联网在很多方面都有助于友谊发展。 首先，互联网使交流更加便捷。你无论在哪里或者在做什么，都可以和朋友保持联系。通过使用智能手机、平板电脑或电脑，你可以是在家里也可以是在外面都能与他人联络。 其次，互联网也使交流变得更加有趣了。传统的沟通方式，如信件和电话，有局限且费时。但是(通过互联网)，你可以在线与朋友共享照片、视频、新闻报道和网站。你可以用一个表情符号或一张图片简短地回复信息。你可以使用这么多的在线工具，让交流变得有创意！ 第三，在线交流实际上可以让人们彼此更亲近。现在，只要点一下鼠标，就能找到你的朋友。无论何时有人需要帮助，来自世界各地的朋友可以立即提供有用的建议或信息。这能让朋友们感到被爱和被关心。对我来说，这是一个非常发人深省的论点，因为它指出了线上友谊的好处。正如这一方面的权威艾琳·肯尼迪·摩尔所指出的，网络朋友“填补了现实生活中朋友无法填补的空白”。 最后，我相信互联网能使人们更紧密地联系在一起，让朋友间的交流更加方便和有趣。 Ⅰ.阅读单词——识记 1．an authority on food 食品方面的权威人士 2．thought-provoking questions 发人深省的问题 3．use emojis in messages 在消息中使用表情符号 4．e-reader tablets 电子阅读器平板电脑 5．smartphone apps 智能手机应用程序 6．trivial matters 琐事 7．a shallow understanding of a language 对语言的浅薄理解 8．give someone a hug 给某人一个拥抱 Ⅱ.核心单词——练通 1．creative thinking 创造性思维 2．the main focus 主要焦点 3．a brief description 简洁的描述 4．a popular opinion 普遍看法 5．table of contents 目录 6．a rewarding experience 有益的经历 7．a concerned parent 一位忧心忡忡的家长 8．win an argument 赢得争论 9．replace an old habit 改掉旧习惯 Ⅲ.拓展词汇——用活 1．a harmless animal 无害的动物 →harmful habits有害的习惯 →do harm to对……有害 2．have an argument with sb与某人争吵 →argue over money issues为金钱问题争吵 3．concentrate his mind on the task 他集中注意力在任务上 →make a concentrated effort集中努力 →lack of concentration 注意力不集中 4．additional information 额外信息 →make an addition to 增加 →add value to 为……增值 5．theoretical basis 理论基础 →basic skills 基本技能 →be based on hard work基于努力工作 6．have limited access 拥有有限的访问权 →within limits 在限度内 →several limiting conditions一些限制条件 Ⅳ.重点短语——再现 第一组　汉译英 1．just a click away 　　　　　 只需点击一次(就可得到或使用) 2．compare to... 与……相比 3．in addition 除此之外 4．on the basis of... 在……基础上 5．be honest about 对……诚实 6．focus on 关注 7．be concerned with 关心…… 学生用书第28页 第二组　英译汉 8．become obsessed with　　 变得着迷于…… 9．on the move 在行进中；在移动中 10．give a brief response to... 简短回应 11．care for 照顾，照料 12．point out 指出 13．stay in touch with 与……保持联系 14．be in contact　 接触；联络 Ⅴ.典型句式——默背 1．While the Internet can bring people closer together (虽然互联网可以让人们更亲近。while引导让步状语从句)，it can also harm friendships. 2．According to a parenting expert，Denise Daniels，communicating through a screen makes it more difficult for children to concentrate or show kindness to others (使儿童更难集中注意力或对他人表示善意。make＋it＋形容词/名词＋for sb to do sth). 3．It is these skills that (正是这些技能。强调句型)enable us to develop lifelong friendships. 4．You can stay in touch with friends no matter where you are or what you are doing (无论你在哪里或者在做什么。“no matter＋疑问词”引导的让步状语从句).　 Ⅰ.核心词汇练全 harm vt.& n．伤害，损害(harmful adj.有害的，导致损害的harmless adj.无害的；无恶意的) do...harm/do harm to... 对……有害　　　 There is no harm in doing sth 做某事无害处；不妨做某事 be harmful to... 对……有害处　　 (1)Some computer viruses can be harmful (harm) to your system and steal your personal information.
