英语六级作文碳排放Carbon Emissions: A Looming Shadow on Our Future The issue of carbon emissions has transitioned from a whispered concern in scientific circles to a deafening roar across the globe. It's no longer a matter of 'if' but 'when' wewill face the music of our carbon-intensive ways. The evidence is irrefutable: rising sea levels, extreme weather events, and melting glaciers all point to a planet on the brink. We've been living on borrowed time, and the bill is coming due. (living on borrowed time - enjoying a period of success that is not likely to last) The crux of the problem lies in our insatiable appetite for fossil fuels. Coal, oil, and gas, the triumvirate powering our modern lives, are also theprimary culprits behind the escalating carbon dioxide levels in our atmosphere. This invisible gas acts like a blanket, trapping heat and causing the planet to warm at an alarming rate. The consequences are far-reaching, impacting not justthe environment but also our economies, societies, and ultimately, our very existence. (the crux of the problem - the most important part of a problem) The responsibility to curb carbon emissions falls on everyone's shoulders. Governments need to enact stricter environmental regulations and incentivize the transition to cleaner energy sources. Businesses must embrace sustainable practices, investingin green technologies and reducing their carbon footprint. Individuals, too, havea critical role to play. By making conscious choices in our daily lives – fromthe cars we drive to the food we eat – we can collectively make a difference.It's time to break free from the shackles of convenience and embrace a more sustainable way of life. (break free from the shackles of - to escape from something that restricts you) The transition to a low-carbon future won't be easy. It requires a fundamental shift in our thinking, our habits, and our priorities.It's about moving beyond short-term gains and embracing a long-term vision for a healthier planet. It's about understanding that the cost of inaction far outweighs the cost of action. (the cost of inaction - the negative results of not doing something) But amidst the challenges, there's a glimmer of hope. Innovative technologies like renewable energy, carbon capture and storage, and electric vehicles offer promising solutions. A growing global movement is demanding action on climate change, with people from all walks of life joining the fight for asustainable future. (from all walks of life - from every kind of social or economic position) The time for complacency is over. We stand at a crossroads, facing a choice that will determine the fate of generations to come. Let us choose wisely, let us choose action, and let us leave behind a legacy of a healthy planet, not a barren wasteland. Let's turn the tide on carbon emissions and write a new chapter in our planet's history, one where sustainability and harmony with nature prevail. (turn the tide - to cause a situation to change in the opposite direction)。

2023年高考英语外刊时文精读精练(14)Climate change and coral reefs气候变化与珊瑚礁主题语境:人与自然主题语境内容:自然生态【外刊原文】(斜体单词为超纲词汇,认识即可;下划线单词为课标词汇,需熟记。
)Human beings have been altering habitats—sometimes deliberately andsometimes accidentall y—at least since the end of the last Ice Age. Now, though, that change is happening on a grand scale. Global warming is a growing factor. Fortunately, the human wisdom that is destroying nature can also be brought to bear on trying to save it.Some interventions to save ecosystems are hard to imagine andsucceed. Consider a project to reintroducesomething similar to a mammoth(猛犸象)to Siberiaby gene-editing Asian elephants. Their feeding habits could restore the grassland habitat that was around before mammoths died out, increasing the sunlight reflected into space and helping keep carbon compounds(碳化合物)trapped in the soil. But other projects have a bigger chance of making an impact quickly. As we report, one example involves coral reefs.These are the rainforests of the ocean. They exist on vast scales: half a trillion corals line the Pacific from Indonesia to French Polynesia, roughly the same as the number of trees that fill the Amazon. They are equally important harbor of biodiversity. Rainforests cover18% of the land’s surface and offer a home to more than half its vertebrate(脊椎动物的)species. Reefs occupy0.1% of the oceans and host a quarter of marine(海洋的)species.And corals are useful to people, too. Without the protection which reefs afford from crashing waves, low-lying islands such as the Maldives would have flooded long ago, and a billion people would lose food or income. One team of economists has estimated that coral’s global ecosystem services are worth up to $10trn a year. reefs are, however, under threat from rising sea temperatures. Heat causesthe algae(海藻) with which corals co-exist, and on which they depend for food and colour, to generate toxins(毒素)that lead to those algae’s expulsion(排出). This is known as “bleaching(白化)”, and can cause a coral’s death. As temperatures continue to rise, research groups around the world are coming up with plansof action. Their ideas include identifying naturally heat-resistant(耐热的)corals and moving themaround the world; crossbreeding(杂交)such corals to create strains that are yet-more heat-resistant; employing genetic editing to add heat resistance artificially; transplantingheat-resistant symbiotic(共生的)algae; and even repairing with the bacteria and other micro-organismswith which corals co-exist—to see if that will help.The assisted evolution of corals does not meet with universal enthusiasm. Without carbon reduction and decline in coral-killing pollution, even resistant corals will not survive the century. Some doubt whetherhumans will get its act together in time to make much difference. Few of these techniques are ready for action in the wild. Some, such as gene editing, are so controversial that it is doubtful they will be approved any time soon. scale is also an issue.But there are grounds for optimism. Carbon targets are being set and ocean pollution is being dealt with. Countries that share responsibilities for reefs are starting to act together. Scientific methods can also be found. Natural currents can be used to facilitate mass breeding. Sites of the greatest ecological and economical importance can be identified to maximise benefits.This mix of natural activity and human intervention could serve as a blueprint (蓝图)for other ecosystems. Those who think that all habitats should be kept original may not approve. But when entire ecosystems are facing destruction, the cost of doing nothing is too great to bear. For coral reefs, at least, if any are to survive at all, it will be those that humans have re-engineered to handle the future.【课标词汇精讲】1.alter (通常指轻微地)改动,修改;改变,(使)变化We've had to alter some of our plans.我们不得不对一些计划作出改动。

低碳环保作文800字高中英语Low-carbon and Environmental Protection。
In recent years, the issue of environmental protection has become increasingly prominent. As a responsible citizen, it is our duty to take actions to reduce carbon emissions and protect the environment. In this essay, I would like to discuss the importance of low-carbon living and propose some practical measures to achieve it.Firstly, low-carbon living is crucial for the sustainable development of our planet. With the rapid industrialization and urbanization, carbon emissions have reached an alarming level. The excessive release of greenhouse gases, such as carbon dioxide, is causing global warming and climate change. It is high time that we realize the urgency of reducing carbon emissions and adopting a low-carbon lifestyle.To achieve low-carbon living, we can start by conserving energy. Energy consumption is one of the major contributors to carbon emissions. We should make a conscious effort to turn off lights and electrical appliances when they are not in use, and replace traditional incandescent bulbs with energy-efficient LED lights. Furthermore, we should choose energy-saving appliances and use them efficiently. For example, we can set our air conditioners to a moderate temperature and avoid unnecessary use of heating or cooling devices.In addition to conserving energy, we should also promote green transportation. The transportation sector is a significant source of carbon emissions. Instead of relying heavily on private cars, we can choose to walk, cycle, or take public transportation whenever possible. Carpooling and ride-sharing are also effective ways to reduce carbon emissions. By adopting these measures, we not only reduce carbon emissions but also improve air quality and alleviate traffic congestion.Furthermore, we should pay attention to our daily consumption habits. The production and transportation of goods consume a large amount of energy and generate substantial carbon emissions. To reduce our carbon footprint, we should opt for productswith low carbon emissions and support eco-friendly companies. We can also reduce waste by practicing the 3Rs: reduce, reuse, and recycle. By reducing our consumption of single-use items and reusing or recycling materials, we can significantly reduce carbon emissions and protect the environment.Apart from individual actions, government policies and international cooperation are essential in achieving low-carbon living. Governments should implement stricter regulations on carbon emissions and promote the development of renewable energy sources. International cooperation is also crucial in addressing climate change. Countries should work together to reduce carbon emissions and support developing nations in their efforts to adopt low-carbon technologies.In conclusion, low-carbon living is of great importance for the sustainable development of our planet. By conserving energy, promoting green transportation, and adopting eco-friendly consumption habits, we can reduce carbon emissions and protect the environment. It is our collective responsibility to take actions and work towards a low-carbon future. Let us strive for a greener and more sustainable world.。
