2026年4月25日雅思写作真题
Some claim that aviation contributes significantly to environmental pollution and accounts for a greater share of fuel consumption, so air travel should be discouraged. Although aircraft consume fossil fuels and emit substantial amounts of greenhouse gases, I disagree that it should be restricted.
一些人认为，航空业对环境污染贡献显著，并占据了较大比例的燃料消耗，因此应当限制航空出行。尽管飞机消耗化石燃料并排放大量温室气体，我仍然不同意应当对其进行限制。
Admittedly, modern air travel consumes large amounts of aviation fuel and significantly increases environmental impacts. This is primarily because most commercial aircraft still rely on fossil-based jet fuels, which are not only finite but also highly carbon-intensive. During flights, the formation of contrails consisting of water vapor at high altitudes, where their warming effects are even more pronounced, can intensify atmospheric warming. Worse still, substantial quantities of carbon dioxide and nitrogen oxides emitted by aircraft not only exacerbate climate change but also greatly pollute the air that people breathe regularly. With global passenger demand rising steadily each year, the total volume of emissions from aviation continues to grow. If this trend remains unchecked, it will accelerate the depletion of limited energy resources and place immense pressure on already strained ecosystems, thereby undermining long-term environmental sustainability.
诚然，现代航空运输消耗大量航空燃料，并显著加剧环境影响。这主要是因为大多数商用飞机仍然依赖化石基喷气燃料，这类燃料不仅是有限资源，而且碳排放强度很高。在飞行过程中，高空中由水蒸气形成的凝结尾迹，其增温效应更为明显，会进一步加剧大气变暖。更糟糕的是，飞机排放的大量二氧化碳和氮氧化物不仅加剧气候变化，还严重污染人们日常呼吸的空气。随着全球航空客运需求逐年稳步上升，航空排放总量也在持续增长。如果这一趋势得不到遏制，将加速有限能源资源的消耗，并对本已承受巨大压力的生态系统施加沉重负担，从而破坏长期的环境可持续性。
However, imposing strict limits on air travel would not effectively eliminate pollution or reduce fuel consumption, but would instead generate far-reaching negative consequences. From a carbon emissions perspective, cars, rather than aircraft, are among the largest contributors to air pollution globally. They release large amounts of carbon dioxide and other harmful gases, which are major drivers of climate change and poor air quality. This impact is magnified by the sheer number of vehicles on the road, leading to traffic congestion that further exacerbates the problem. While air travel consumes significant amounts of fossil energy, it is less frequent for the average individual, and its per capita consumption is much lower than that of daily car use. From a socio-economic perspective, discouraging flights could have severe economic and social repercussions, particularly for the global tourism industry. Air travel plays a vital role in connecting people worldwide and facilitating business and tourism, despite planes consuming considerable amounts of energy per kilometer. For long-distance travel, there are few practical alternatives. A reduction in flights could harm industries reliant on tourism and international trade, resulting in job losses, economic downturns, and decreased living standards.
然而，对航空出行施加严格限制并不能有效消除污染或减少燃料消耗，反而会带来深远的负面影响。从碳排放的角度来看，汽车而非飞机，才是全球空气污染的主要来源之一。汽车排放大量二氧化碳及其他有害气体，这些都是气候变化和空气质量恶化的重要驱动因素。由于道路上车辆数量庞大，这一影响被进一步放大，并导致交通拥堵，从而加剧问题。尽管航空出行消耗大量化石能源，但对普通人而言其发生频率较低，人均能耗远低于日常汽车使用。从社会经济角度来看，限制航班可能带来严重的经济和社会影响，尤其是对全球旅游业而言。航空运输在连接全球人口、促进商业往来和旅游发展方面发挥着至关重要的作用，尽管飞机在单位距离上消耗大量能源。对于长途出行而言，几乎没有切实可行的替代方案。减少航班可能会损害依赖旅游和国际贸易的产业，导致失业、经济衰退以及生活水平下降。
In conclusion, although aviation undeniably intensifies environmental degradation through high fuel consumption and emissions, restricting it is neither effective nor practical. Compared with widespread car use, its overall impact is relatively limited, while its economic and social significance remains indispensable, making alternative solutions far more viable.
总而言之，尽管航空业确实通过高燃料消耗和排放加剧环境恶化，但对其进行限制既不有效，也不现实。与广泛的汽车使用相比，其总体影响相对有限，而其经济和社会重要性又不可替代，因此寻找其他解决方案更为可行。
