原文呈现

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”。

Firstly②，talking online is no replacement③ for face­to­face④ contact—images really cannot replace a real­life⑤ smile or hug.According to a parenting⑥ expert Denise Daniels，communicating through a screen makes it more difficult for children to concentrate⑦ or show kindness to others.[2] As we know，important social skills are developed through direct contact⑧ with other people.It is these skills that enable⑨ us to develop lifelong⑩ friendships.[3]

[2]句中用动名词作主语；it作形式宾语。

[3]本句是强调句，强调主语these skills。

Secondly⑪，the Internet can make people self­centred⑫—not thinking of anyone or anything but themselves.For example⑬，instead of⑭ having proper conversations with their friends，some people are only concerned with⑮ their online popularity⑯—How many “likes” did I get? How many followers⑰ do I have？—though we know that the number of “likes” or followers cannot compare to having long­term⑱ and rewarding⑲ friendships.In addition⑳，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 face­to­face communication，and less on online communication.This is the best way to maintain healthy relationships.

译文参考

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接触，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，让孩子们更难集中精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能够发展终生的友谊。

其次，互联网会使人们变得以自我为中心，只关注自己，不关注其他人和事。例如，一些人不再和朋友进行真正的交谈了，他们只关心自己网上的人气——我得了多少个“赞”？我有多少追随者？——尽管我们知道“赞”或追随者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。关于有趣的猫形象的帖子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有没有诚实地告诉你他们是谁。因此，对于那些容易受到影响或过于信任的人来说，上网可能特别危险。

在我看来，朋友们应该更多地关注面对面的交流，更少地关注在线交流。这是保持健康关系的最好方法。
