原文呈现

The Internet：a world without frontiers①

The Internet has the power to connect people across the world to a single shared community.Billions②of people in different parts of the world have joined it already，and obviously many more will follow.Even in the countryside，the Internet enables people to reach beyond their villages and get in touch with the outside world.We can achieve almost anything online—with access③to the Internet come some truly life­changing advantages.

One of the greatest advantages of the Internet lies in the quick and easy access to a huge amount of information.To a certain extent，the world's knowledge is all at our fingertips.With the click④of a mouse or the touch of a button⑤，it is possible to find out almost anything we care to know，from recipes to travel packages，from military affairs⑥ to learning resources.In the time it takes to find one book in the library，we can use a search engine to bring up⑦ millions of results.No wonder the Internet has now become the first place that the majority⑧ of people turn to for information. [1]

[1] No wonder...是It is no wonder 的省略形式，表示“难怪……；……不足为奇。”

The Internet has also made our lives unbelievably convenient，with all sorts of goods⑨ and services provided by electronic commerce⑩，more commonly known as e­commerce.You can have food delivered⑪ to you using food delivery apps and sites⑫.[2] Gone are the days of searching shop after shop for the perfect pair of boots—you can compare styles and prices quickly and easily in the comfort of your living room. [3] Why wait hopelessly for a taxi in the cold rain？It is now simple and fast to order one with a taxi app.Sit back⑬ and relax indoors for a few warm minutes until the driver arrives.When you wish to go on holiday，you can make all your travel arrangements just in front of the computer.Forgot to carry cash⑭？There is no need to worry―you can pay for almost everything on your smartphone. [4]

[2] have food delivered 运用了“have sth.done”结构，表示“使/让某事被做”。

[3] 句中gone are the days...使用了倒装结构，意为“……的日子一去不复返了”。

[4] There is no need to do...表示“没有必要做某事”。

Above all else⑮，the Internet helps us establish⑯ and maintain social ties.With all sorts of communication software⑰，physical distance no longer gets in the way.No matter where we are，we are able to keep in contact with loved ones，find long­lost friends and discover whole new communities who share our hobbies. [5]An instant⑱ message，a group chat，a video call，a comment⑲ on an update―there are endless ways to share our views or let someone know we care about them.

[5] No matter where we are 为让步状语从句，表示“无论我们在何处……”。

However，while the Internet brings many valuable advantages，being connected has its problems.[6] As with any great invention，we must be aware⑳ of these problems and be careful to use the Internet properly and responsibly.Only in this way can the Internet be a place of discovery，wonder and inspiration for everyone. [7]It is truly a world without frontiers.

[6] 此处while引导让步状语从句，表示“虽然，尽管”。

[7] Only in this way can...此处为部分倒装句。

译文参考

互联网：一个没有边界的世界

互联网能够将世界各地的人们连接到一个共享的社区。世界各地的数十亿人已经加入，而且显而易见会有更多的人加入。即使是在农村，互联网也能让人们接触到乡村之外的世界，与外界取得联系。在网上我们几乎什么都能做到，接入互联网带来了一些实实在在改变我们生活的好处。

互联网的最大优点之一是可以方便快捷地获取大量信息。在某种程度上，我们能随时了解全世界的知识。我们只要点击一下鼠标或按一下按钮，我们几乎可以查明我们想知道的任何事情，从食谱到旅行包，从军事事务到学习资源。在图书馆找一本书所花的时间里，我们可以用搜索引擎找到数百万条的结果。难怪互联网现在已经成为大多数人查找信息的首选途径。

互联网也给我们的生活带来了难以想象的便利，更通常地被称为e­commerce的电子商务提供了各种商品和服务。你可以使用送餐应用程序和网站让食物送到你身边。一家店一家店寻找那双最合适的靴子的日子一去不复返了，人们可以舒舒服服地待在客厅里轻松快捷地比较款式和价格。为什么在寒冷的雨中绝望地等出租车？现在，在打车软件上叫一辆出租车很简单。然后舒服地坐在室内放松几分钟，直到司机到来。当你想去度假时，你可以在电脑前就作好所有的旅行安排。忘了带现金？没有必要担心——你可以用智能手机支付几乎所有的费用。

最重要的是，互联网帮助我们建立和保持社会关系。有了各种通信软件，现实距离不再是阻碍。无论我们在哪里，我们都能与所爱的人保持联系，找到失散已久的朋友，并发现与我们有共同爱好的全新群体。一个即时消息、一个群聊、一个视频电话、一个更新的评论——有无数的方式来分享我们的观点或让别人知道我们关心他们。

然而，尽管互联网带来了许多宝贵的优势，网络连接也有它的问题。就像任何伟大的发明一样，我们必须意识到这些问题，并恰当地、负责任地谨慎使用互联网。只有这样，互联网才可以成为一个让每个人有所发现、获得惊奇和灵感的地方。这是一个真正没有边界的世界。
