Suggested structure for writing Supporting Paragraph 1 (Advantages/Disadvantages) • Sentence 1- Topic sentence (Advantage 1 or Disadvantage 1) • Sentence 2-3- Explain how this is an advantage/disadvantage • Sentence 4- Example • Sentence 5-Link

Answer 1

Ответ:

While one of the major benefits of biofuels is their renewability, one of their greatest drawbacks is water use. Biofuels might have seemed like a win-win solution to the problem of non-renewable energy at first, however, this impression can’t have lasted for long, and then, people must have started to realise how much water, which is a scarce non-renewable resource, is required to produce them. Indeed, since biofuels are mostly plant-based, we need crops to make them, and all these crops need to be irrigated. For example, just to produce 50 million gallons of ethanol, 150–200 million gallons of water are used, and people consume about 14 billion gallons of ethanol every year. In my opinion, people should manage the production process wisely and figure out how to use as little water as possible.

Объяснение:

Надо написать параграф об одном недостатке или достоинстве биотоплива, придерживаясь структуры из задания.

Структура:

• Предложение 1: Topic sentence (предложение, задающее тему, в котором говорится о достоинстве/недостатке, которое вы будете описывать дальше)
• Предложения 2-3: Объяснить, почему это является достоинством/недостатком
• Предложение 4: Пример
• Предложение 5: Link (вывод + привязка к topic sentence)

Еще надо использовать past modals, в том числе must have, can't have, might have (в тексте подчеркнуты)

Перевод:

В то время как одно из главных преимуществ биотоплива - это возобновляемость, одно из главных его недостатков - это использование воды. Изначально биотопливо могло казаться выигрышным решением проблемы невозобновляемой энергии, однако это впечатление не могло быть долгим, и потом люди, должно быть, стали осознавать, как много воды, которая является скудным невозобновляемым ресурсом, требуется, чтобы его произвести. Действительно, так как биотопливо, в основном, основывается на растениях, чтобы его сделать, нам нужны посевы, а посевы нужно орошать. Например, просто чтобы произвести 50 миллионов галлонов этанола, используется 150-200 миллионов галлонов воды, а люди потребляют около 14 миллиардов галлонов этанола в год. По моему мнению, люди должны мудро управлять процессом производства и придумать, как использовать как можно меньше воды.

Answer 2

Biofuels have gained significant attention as a potential alternative to conventional fossil fuels. One of the advantages of biofuels is their renewable nature. Unlike fossil fuels, which are finite resources, biofuels are derived from organic materials such as crops, algae, and waste, which can be continuously replenished through sustainable farming practices. This not only reduces our dependence on fossil fuels but also helps mitigate the environmental impact associated with their extraction and combustion.

Another advantage of biofuels is their potential to reduce greenhouse gas emissions. When biofuels are burned, they release carbon dioxide, but the amount released is roughly equivalent to the amount absorbed by the plants during their growth. This creates a carbon-neutral cycle, making biofuels a more environmentally friendly option compared to fossil fuels, which release carbon dioxide that has been trapped for millions of years.

Furthermore, the use of biofuels can contribute to rural development and job creation. Biofuel production requires a significant amount of raw materials, which can be sourced locally, providing economic opportunities for farmers and rural communities. Moreover, biofuel production facilities can create jobs in manufacturing, distribution, and research and development, thereby boosting local economies.

However, there are also disadvantages associated with biofuels. One major concern is the potential impact on food security. As biofuels are often derived from crops such as corn, soybeans, and sugarcane, there is a risk of diverting these resources away from food production. This can lead to higher food prices and limited availability, particularly in regions heavily reliant on these crops for sustenance.

Additionally, the production of biofuels requires large amounts of land, water, and energy. This can lead to deforestation, habitat destruction, and competition for resources, which may have unintended negative consequences for biodiversity and ecosystems.

In conclusion, biofuels offer several advantages such as their renewable nature, potential to reduce greenhouse gas emissions, and contribution to rural development. However, they also come with disadvantages, including the potential impact on food security and environmental concerns associated with their production. It is crucial to carefully consider and address these issues to ensure the sustainable and responsible use of biofuels in the future.
