有人认为要了解其他国家出国旅行是有必要的，另一些人认为所有的信息都可以通过电视和网络获得，所以没必要在出国旅行了，双边讨论？

这是一道双边类大作文。题目给出的双方观点是对立的，因此在文章结构上，双方观点都要进行讨论，并选择支持一方或者两方都反对。在审题时，各位考鸭一定要注意题目中的限定“to learn about other countries”，也就是说不论讨论出国旅游还是从网上了解信息，都是要围绕着这个目的来进行讨论。下面月半鸭就带大家一起来具体分析下这两个方法。

我们先来看通过电视和网络了解其他国家的利弊。

这个方式好处有两个，一是网上有大量的关于其他国家描述的信息，不论是旅行者的游记还是专业纪录片，而且其中还包含许多专业的见解和背景介绍，这些都有助于我们去了解一个国家。二是通过这个方式能够节约时间、金钱去了解更多的国家和地区。相比出国旅游的实际开销，网络和电视的成本基本可以忽略不计，同时也节省在路途上奔波的时间。

但这个方式的坏处也很明显，而且这也恰恰是出国旅游是有必要的理由。

一是通过网络和电视了解一个国家，所带给人的观感是不完整的。当你去实地旅游所能体验到的视觉和听觉，和通过网络了解到的是完全不同的。同时，去国外旅游还能品尝当地美食、参与当地的节日活动、与当地人交谈沟通，这些通过网络和电视无法体验到的，也有助于我们去深入了解这个国家

二是网络信息虽然丰富，但是很多都是二手信息，带有发布者的主观判断和筛选。而亲身去国外旅游，有助于你更直接的了解这个国家并做出自己的独立判断。

It is quite common these days for people to travel internationally to improve understanding of other countries.  However, some people argue that there will be no need to get to foreign countries considering all the information is widely available on TV or Internet.  

Admittedly, knowledge gained from on TV and Internet features a wider range than that gained from travelling.  Abundant information can be available from a variety of sources ranging from documentaries and other tourism programs produced by professional broadcast companies to travel stories, adventures and images from avid travelers.  In comparison，what people experience is probably incomplete and partial, sometimes lopsided.  Besides, by watching TV and browsing through pages online people can form a general conception of a country with the least effort in terms of time and expense.  

In spite of that, I believe that traveling still has much of a role to play in people’s life where online information can never reach a comparable level.  Traveling physically, which involves all the senses, allows people to have a more firsthand experience and in-depth insight of the local scenery and cultural heritage.  For example, apart from having a general idea of a country, people can engage themselves in all sorts of activities such as basking at the beach, interacting with the locals in-person, strolling the streets of a historic city or having a taste of the local cuisine.

In conclusion, I think the importance of traveling around cannot be denied.  It is no secret, even less highfaluting talk; traveling abroad has much more to offer which are beyond the reach of simply sitting in front of the screen.
