问题     Some people believe that air travel should be restricted because it causes serious pollution and uses up the world’s fuel resources. To what extent do you agree or disagree?
选项
答案 Aeroplanes are becoming the top choice of transportation for more and more people, as they are by far the fastest way to travel between cities and countries. While some people claim air travel should be limited because of its massive emissions of carbon dioxide and relatively high fuel consumption, I personally think that they are oversimplifying the situation. Admittedly, air travel produces greenhouse gases and is fuel-consuming, but one fact that needs to be highlighted is that the main source of the world’s emissions is private cars rather than aeroplanes. Further, alternative energies are being explored and some have already come into being. It is imaginable that in the near future planes will be powered by cleaner energy. Besides, industrial pollution is still the number one source of pollution, so it is unfair and unreasonable to blame all these on air travel or even put restrictions on it. Rather, air travel plays an irreplaceable role in our daily lives and world economy. The most obvious merit of travelling by air is its speed, which means geographical limitations are not a problem any more. Every hour of every day, millions of business and leisure travellers alike are taking advantage of aeronautical technology to hurtle safely through the air in a metal tube. People are therefore granted the chance to be able to attend a meeting in a different city or visit an old friend living far away and make it home the very next day or even the same day if needs be. Thus, the convenience and efficiency of life has been improved dramatically, and we are actually leading a lifestyle that used to be completely impossible. On a larger scale, the system of air travel, more importantly, supports the global economy by connecting business across the world. Companies today have many offices overseas, countries import and export goods between each other on a daily basis. Without aeroplanes, none of this would be easy, or perhaps even exist. So overall, I am optimistic about the future of air travel and firmly believe that, as one of the most important parts of the world’s transportation infrastructure, it should be invested in and developed even more.
