The Internet: a world without frontiers
互联网：无疆世界
◆ 内容分析
　　【What】本板块的话题是“网络是无疆世界”，旨在引导学生辩证看待互联网的利弊。文章介绍了互联网的强大功能：它把全世界连接成一个共享社区；它给人类生活带来种种好处，比如它能够快捷地提供人们所需的海量信息；其电子商务提供的各种商品和服务给我们带来了生活上的便利；它还能帮助人们建立和保持社交联系。但与此同时，互联网也存在一些问题，我们应注意合理使用。
　　【Why】文章在介绍互联网给人类生活带来的种种便利的同时，也指出了其存在的一些问题，由此可以引发学生的辩证思考，培养他们的批判性思维能力，使他们能正确使用互联网，成为负责任的互联网用户。
　　【How】文章的语篇类型为议论文，结构清晰、逻辑缜密。首段即表明论点，二、三、四段作为全文主体，分别列举了互联网给人类生活带来便利的三个方面；第五段是总结段，它指出尽管互联网有着巨大的优势，却也存在着一些问题，建议人们应正确、负责任地使用网络。
本文写作的最大特点是全文每一段都有一句主题句来引领，文章结尾句与标题相呼应，起到了画龙点睛的作用。文中多次运用举例、比较等写作方法，使论证更具体化。文章中使用了 one of the greatest advantages、also、above all else、however 等作为衔接手段，有助于学生迅速定位关键信息，把握文章结构。

How do you understand the title “The Internet: a world without frontiers” after you read the article
In my opinion, this title can be understood from the following three aspects. Firstly, “The Internet has the power to connect people across the world to a single shared community.” On the Internet, there is no boundary between countries, and there is no boundary between countryside villages and modern cities.
boundary| ba ndri|边界；界限；分界线
People in different parts of the world can have access to the Internet.
Secondly, the life-changing advantages brought about to us by the Internet are without frontiers—we can enjoy its benefits together.
Thirdly, the Internet is truly a world without frontiers only if we use it properly and responsibly to make it a place of discovery, wonder and inspiration for everyone.

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.
Why wait hopelessly for a taxi in the cold rain It is now simple and fast to order one with a taxi app. Sit back and relax indoors for a few warm minutes until the driver arrives.

(3) Write a paragraph to compare the life before and after smartphones were invented based on the table above.
Learn this: When giving your opinion, you can make a “before-and-after” comparison. By showing the reader what the situation was like in the past and what it is like now, you can make your argument more convincing and more likely to be accepted by the reader.
Early mobile phones were not as functional as they are now and were used for basic communication needs: telephoning and messaging. Mobile Internet was not available then, so people depended on their computers or laptops to surf the Internet.
functional| f k nl| 实用的
Since the invention of the smartphone, mobile access to the Internet has helped users with more than just basic needs. They could now do most daily tasks on a device that fits into their pockets, for example, instant video calls, online shopping, watching videos, reading the latest news reports, and searching for information anywhere and at any time.
