The process of producing power from coal can be depicted in the following diagram. The process consists of 10 distinct stages, starting from coal mining and concluding with the distribution of electricity to different areas.

To begin, coal is extracted from the mines and ground into a fine powder under expert supervision and with the use of machinery. This initial process ensures that the coal is in a suitable form for further utilization. The next stage involves the separation of solid waste and gas through a gasifier. This allows for the efficient extraction of useful gasses from the coal.

Once the separation is complete, the temperature of the gas is lowered in a nearby cooler. This cooled gas is then sent to a gas power plant, where it is utilized to generate electricity. At the same time, any remaining waste, known as heat waste, is effectively eliminated by the facility, ensuring minimal environmental impact.

Finally, at the conclusion of the process, the electricity generated is distributed to homes and businesses through a network of cables. This ensures that the power produced from coal reaches the intended recipients and fulfills their energy needs.

1. "producing power" -> "generating power"
   Explanation: "Generating power" is a more precise and formal phrase commonly used in technical contexts to describe the process of creating electricity from a particular energy source like coal.

2. "fine powder" -> "finely ground particles"
   Explanation: "Finely ground particles" provides a clearer and more descriptive term for the coal after it has been processed, emphasizing the small size of the particles.

3. "separation of solid waste and gas" -> "separation of solids and gases"
   Explanation: "Solids" and "gases" are more precise terms than "solid waste" and "gas" respectively, providing a clearer description of the components being separated.

4. "utilized to generate electricity" -> "employed in electricity generation"
   Explanation: "Employed in electricity generation" offers a more formal and sophisticated phrasing, enhancing the technical tone of the sentence.

5. "known as heat waste" -> "referred to as residual heat"
   Explanation: "Referred to as residual heat" provides a more technical and formal term for the waste heat produced during the process, maintaining consistency with the technical language used throughout the essay.

6. "distributed to homes and businesses" -> "dispersed to residential and commercial establishments"
   Explanation: "Dispersed to residential and commercial establishments" offers a more formal and varied phrasing, contributing to the diversity of vocabulary in the essay.

Band điểm Task Achivement ước lượng: 7

Band Score: 7.0

Explanation: The essay provides a clear overview of the process of producing electricity from coal, outlining 10 distinct stages. It covers all the key stages of the process, including coal mining, grinding, gas separation, gas cooling, electricity generation, and distribution. The essay also describes the purpose and outcome of each stage, highlighting the main features of the process.

How to improve: To improve, the essay could extend the discussion of some stages to provide more detailed descriptions or explanations where relevant. Additionally, ensuring that all information is relevant and directly contributes to the understanding of the process would enhance the overall clarity and coherence of the essay.

Band điểm Coherence & Cohesion ước lượng: 7

Band Score: 7.0

Explanation: The essay logically organizes the information and ideas, presenting a clear progression throughout the process of producing electricity from coal. Each stage is clearly delineated, starting from coal extraction to the distribution of electricity. The use of cohesive devices such as transitional phrases ("To begin," "Once," "Finally") aids in the logical flow of ideas. Additionally, there is a clear central topic within each paragraph, with each paragraph focusing on a specific stage of the process.

How to improve: While the essay effectively uses a range of cohesive devices to maintain coherence and cohesion, there could be a slight improvement in the variety and sophistication of these devices. Additionally, ensuring consistent and appropriate paragraphing throughout the essay would further enhance the organization and clarity of the response.

Band điểm Lexical Resource ước lượng: 7

Band Score: 7.0

Explanation: The essay demonstrates a sufficient range of vocabulary with some flexibility and precision. There is a clear attempt to use less common lexical items, such as "gasifier," "utilization," and "distribution," showing awareness of style and collocation. The vocabulary used effectively conveys the process of coal-powered electricity generation. Some minor errors in word choice and word formation are present, such as "utilization" instead of "use" and "distribution" instead of "distributing," but they do not significantly impede understanding.

How to improve: To improve, focus on using vocabulary with even greater precision and accuracy. Ensure consistency in word choice and pay attention to word forms to avoid minor errors. Additionally, aim to incorporate a wider variety of vocabulary to enhance lexical resource.

Band điểm Grammatical Range & Accuracy ước lượng: 7

Band Score: 7.0

Explanation: The essay demonstrates a good range of complex structures, such as compound and complex sentences, contributing to coherence and cohesion. There is evident control over grammar and punctuation, with the majority of sentences being error-free. Complex structures like "The process consists of 10 distinct stages, starting from coal mining and concluding with the distribution of electricity to different areas" showcase the writer’s ability to vary sentence structures effectively.

How to improve: To aim for a higher score, aim for even greater flexibility and accuracy in sentence structures. While the essay generally demonstrates good control of grammar and punctuation, occasional minor errors or inappropriacies are noticeable. Proofreading for such errors and refining sentence structures further can enhance the overall grammatical range and accuracy.

The diagram illustrates the process of electricity generation from coal, encompassing ten distinct stages, commencing with coal extraction and culminating in electricity distribution to various sectors.

Initially, coal is mined and pulverized into a fine powder under expert supervision and using specialized machinery, facilitating its subsequent utilization. Following this, solid waste and gas are separated via a gasifier, allowing for the efficient extraction of valuable gases from the coal.

Subsequently, the temperature of the gas is reduced in a nearby cooling system. This cooled gas is then conveyed to a gas power plant, where it is harnessed to generate electricity. Simultaneously, any residual waste, referred to as heat waste, is efficiently disposed of by the facility, ensuring minimal environmental repercussions.

Ultimately, the electricity generated is transmitted to residential and commercial areas via an extensive network of cables, ensuring the delivery of coal-derived power to its intended recipients, thereby meeting their energy requirements.
