访问其他国家越来越方便和便宜。请问利弊如何？

这是一篇利弊类大作文，是许久没考过的国际间旅行的话题。题目不算难，讨论利弊前，要先从题目的关键词中寻找线索，这题的关键词包括 easier and more affordable——强调了频率增加，visit other countries——强调国际间的访问，在利弊分析时应该从这两个关键词所涉及的不同层面予以讨论。

我们先来看好处。

首先，能够促进相关行业和经济发展、增加就业机会。国际间旅行更方便和便宜，会促进人们更多的出行，一方面，更多的出行意味着在航空、酒店、景点等地方会产生更多的消费，能够促进了国际旅游行业发展和目的地的经济发展。另一方面，行业发展会带来大量新的工作岗位，能够促进就业。

其次，不同国家间的访问能够促进文化交流。各个国家的学者能够更方便访问其他国家，这将有助于促进国际间的文化交流沟通、减少文化隔阂。而对于旅行者个人来说，也能切身体会不同国家的世俗风情，而不是仅仅通过文字或报道来了解。

再来看坏处，明显的莫过于对环境的负面影响。现在国际间旅行的主要手段依然是飞机和船，更高的使用频次意味着相关交通工具产生的污染也会更加严重，这对于环境是不利的。

Today, it is true that international tourism has become increasingly commonplace thanks to the reduced travel cost. While its benefits are championed by the populace, I will say its negative side deserves equal attention as well.  

While the boom of global journeys is applauded in terms of its leisure aspect, I would focus more on its relevance to other facets of society. One of the merits can be seen from the economic perspective: the surging trend of travelling abroad is a key boost to various industries, whether these be the airline, international tourism, or hospitality industry; apart from consumptions from tourists, it also creates millions of job opportunities. When it comes to cultural level, the convenience of journeying to different countries also acts as a catalyst for cultural exchange, given that more and more students and scholars can afford to study abroad.

However, the aforementioned benefits are not justified enough to represent the entire picture – while focusing on the blessings of popularization of journeying abroad, let’s not be oblivious to its repercussions for the environment. Based on this, the discussion can then move on to handle conundrums as to how to tackle increasingly serious air pollution and exhaustion of fossil fuel resources, both of which are inextricably bound up with the surge in transcontinental flights or cruises. Not to be left behind is the construction of infrastructure like airports, which is gradually encroaching on natural habitats.

From what has been discussed, it is my conclusion therefore, while more people journeying abroad is socioeconomically positive, its repercussion for the ecosystem deserve equal consideration.
