The Internet Harms① Friendships
While the Internet can bring people closer together, it can also harm friendships．[1]
[1]while引导让步状语从句，意为“尽管”。
Firstly, talking online is no replacement② for face-to-face③ contact④—images really cannot replace a real-life⑤ smile or hug⑥．According to⑦ a parenting expert⑧， Denise Daniels, communicating through a screen makes it more difficult for children to concentrate⑨ or show kindness to others[2]． As we know, important social skills are developed through direct⑩ contact with other people．It is these skills that enable us to develop lifelong friendships．[3]
[2]句中communicating through a screen是动词-ing形式作主语，it作形式宾语。
[3]本句是强调句，强调主语these skills。
Secondly ， the Internet can make people self-centred —not thinking of anyone or anything but 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．In addition ， a lot of the content posted on social media is shallow or trivial ．Posts about funny cat images do not necessarily help form meaningful relationships．
Thirdly, online relationships may not be what they appear to be．[4] 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 ．
［4］what引导表语从句。
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．
The Internet Helps Friendships
The Internet can help develop friendships in many ways．
Firstly, the Internet makes communication much more convenient ．You can stay in touch with friends no matter where you are or what you are doing．Using a smartphone, a tablet or a computer, you can be in contact at home and also when you are on the move ．[5]
[5]using a smartphone, a tablet or a computer为动词-ing形式作状语，when引导时间状语从句。
Secondly, the Internet has also made communication more fun．Traditional ways of communicating, like letters and phone calls, can be limiting and take time．However, you can share photos, videos, news stories and websites with your friends online．You can give a brief response to a message with an emoji or a picture．There are so many online tools you can use to be creative ！
Thirdly, online communication can actually bring people closer to each other．Nowadays, your friends are just a click away．Whenever someone needs help, 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-provokingB51 argument, as it points outB52 the benefits of online friendships．As Eileen Kennedy-Moore, an authorityB53 on the subject, points out, online friends “fill holes real-life friends can't”．
Finally, I believe the Internet brings people closer together and makes communication with friends more convenient and interesting[6]．
[6]I believe为主句，believe后面为省略了that的宾语从句。brings与makes是并列的谓语动词， more convenient and interesting是communication with friends的补足语。
互联网损害友谊
虽然互联网可以拉近人们之间的距离，但也会损害友谊。
首先，网上聊天并不能取代面对面的交流——虚拟形象真的无法取代现实生活中的微笑或拥抱。据育儿专家丹尼斯·丹尼尔斯说，通过屏幕进行交流，让孩子们更难集中注意力或对他人表示友好。正如我们所知，重要的社交技能是通过与他人的直接接触而形成的。正是这些技能使我们发展终生的友谊。
其次，互联网会使人们变得以自我为中心，只关注自己，不去想除自己以外的任何人和事。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”？有多少人关注我？——尽管我们知道“赞”或关注的数量无法与拥有长期而有益的友谊相比。此外，在社交媒体上发布的很多内容都是浅薄或琐碎的。发布有趣的猫的图片不一定有助于建立有意义的关系。
第三，网络关系可能不是它们看起来的那样。友谊是建立在信任之上的，但是在线交流时，你绝不可能百分之百地确定和你聊天的人是否以诚相待。因此，对于那些容易受到影响或轻信他人的人来说，上网尤其危险。
在我看来，朋友们应该更多地关注面对面的交流，少关注在线交流，这是保持健康关系的最好方法。
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。无论你在哪里，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，无论你在家里还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。传统的沟通方式，如信件和电话，限制条件较多，而且比较耗时。而通过互联网，你可以在线与朋友共享照片、视频、新闻故事和网站。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。正如本课题的专家艾琳·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，让与朋友的交流更加方便和有趣。
