英语翻译
The internet will open up new vistas (前景),create the global village -- you can make new friends all around the world.That,at least,is what it promised us.The difficulty is that it did not take the human mind into account.The reality is that we cannot keep relationships with more than a limited number of people.No matter how hard the internet tries to put you in communication,its best efforts will be defeated by your mind.
The problem is twofold (双重的).First,there is a limit on the number of people we can hold in mind and have a meaningful relationship with.That number is about 150 and is set by the size of our brain.Second,the quality of your relationships depends on the amount of time you invest (投入) in them.We invest a lot in a small number of people and then distribute what's left among as many others as we can.The problem is that if we invest little time in a person,our engagement with that person will decline (减弱) until eventually it dies into someone I once knew.
This is not,of course,to say that the internet doesn't serve a socially valuable function.Of course it does.But the question is not that it allows you to increase the size of your social circle to include the rest of the world,but that you can keep your relationships with your existing friends going even though you have to more to the other side of the world.
In one sense,that's a good thing.But it also has a disadvantage.If you continue to invest in your old friends even though you can no longer see then,then certainly you aren't using your time to make new friends where you now live.And I suspect that probably isn't the best use of your time.Meaningful relationships are about being able to communicate with each other,face to face.The internet will slow down the rate with which relationships end,but it won't stop that happening eventually.

因特网将开辟新的前景,创造出一个地球村——这意味着你可以在全世界的范围内交友.这至少是因特网向我们许下的承诺.但这难就难在它不能以人类的头脑去思考.事实是我们并不能和超过一定数量的人保持关系.无论因特网费了多大力气来让你们交流,它的努力却被你的个人想法击败.
这个问题是双重的.首先,我们能记住并且能保持良好关系的人是有限的.这个人数大约是150人并且这个数值要由我们的脑容量来决定.其次,你们人际关系的质量取决于你投入时间的多少.我们通常在一小部分人身上花费比较多的时间和精力,而将余下的时间和精力尽可能多的分给其他人.问题是,如果我们在一个人身上没有花费太多的时间和精力,我们和这个人的关系就会越来越淡薄直到这段友谊以“那是我曾经认识的人”而告终.
这当然不是说因特网对社会没有积极的作用,相反,它有很多（积极作用）.但问题不是它允许你增加你的交际圈范围,让你的人际关系扩展到世界的其他地方,而是让你可以同目前的朋友保持良好关系即使你在世界的另一边有更多朋友.
在某种意义上,这是件好事.但是它仍然有着不利的一面.如果你继续在老朋友身上投入时间和精力即使你永远也不可能再见到他们,那么你一定没有在你生活的新环境下去交朋友.我甚至怀疑,这很有可能不是明智的选择.有意义的关系应该让你们之间面对面地相互交流.因特网会让人们友谊结束的速度慢下来,可它终将不能阻止这件事（友谊结束）的发生.
