The graph below shows the production levels of the main kinds of fuel in the UK between 1981 and 2000.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph illustrates the production levels of three main types of fuel—coal, natural gas, and petroleum—in the UK over a 19-year period, from 1981 to 2000. Overall, the most notable feature of the graph is the stark contrast between the trends of coal and natural gas. While coal production experienced a significant decline, natural gas production surged dramatically, especially in the latter part of the period. petroleum, on the other hand, remained relatively stable throughout, with only minor fluctuations.
In 1981, petroleum was the dominant fuel source, with production levels reaching approximately 90 million tonnes (MT). This was closely followed by coal, which accounted for around 80 MT, while natural gas was significantly lower, producing just under 40 MT. Over the next two decades, petroleum maintained its position as the leading fuel source, despite experiencing some fluctuations. By 2000, its production had risen slightly to about 100 MT, following a dip to 90 MT during the late 1980s. coal, however, showed a different trajectory. From 1981 onwards, coal production initially remained stable but then began to decline sharply after 1984, plummeting to approximately 60 MT by 1987. Although there was a brief recovery to 70 MT in 1990, the downward trend resumed, and by 2000, coal production had fallen to just under 35 MT, marking it as the least produced fuel by the end of the period. In contrast, natural gas experienced a remarkable surge in production. It remained stable at around 40 MT until 1990, after which its production began to rise sharply. By the year 2000, natural gas production had surpassed both coal and petroleum, reaching over 100 MT, making it the most produced fuel in the UK at that time.
In conclusion, the production levels of the three main fuels in the UK witnessed divergent trends between 1981 and 2000, with natural gas becoming increasingly dominant, while coal saw a significant decline and Petroleum maintained a relatively steady level.

Gợi ý nâng cấp từ vựng

"the stark contrast" -> "a marked contrast"
Explanation: The phrase "a marked contrast" is more precise and academically appropriate than "the stark contrast," which can sound overly dramatic and informal for academic writing.
"dramatically" -> "significantly"
Explanation: "Significantly" is more precise and less sensational than "dramatically," which can imply an emotional tone not suitable for formal academic writing.
"petroleum, on the other hand" -> "petroleum, in contrast"
Explanation: "In contrast" is a more formal and academically appropriate phrase than "on the other hand," which can sound informal and conversational.
"minor fluctuations" -> "modest fluctuations"
Explanation: "Modest" is a more precise and formal adjective than "minor," enhancing the academic tone of the description.
"was the dominant fuel source" -> "was the primary fuel source"
Explanation: "Primary" is a more precise term than "dominant," which can carry a connotation of superiority that may not be intended in an objective analysis.
"despite experiencing some fluctuations" -> "despite exhibiting fluctuations"
Explanation: "Exhibiting" is more formal and precise than "experiencing," which is somewhat vague and informal for this context.
"plummeting to approximately 60 MT" -> "declining to approximately 60 MT"
Explanation: "Declining" is a more neutral term than "plummeting," which can imply a sudden and drastic drop, which may not accurately reflect the trend in the data.
"brief recovery" -> "temporary resurgence"
Explanation: "Temporary resurgence" is a more formal and precise term than "brief recovery," which is somewhat vague and informal.
"the downward trend resumed" -> "the downward trend continued"
Explanation: "Continued" is a more neutral term than "resumed," which implies a restart of a previous action, which may not be the case here.
"making it the least produced fuel" -> "rendering it the least produced fuel"
Explanation: "Rendering" is a more formal verb than "making," which is somewhat colloquial for academic writing.
"remarkable surge" -> "significant increase"
Explanation: "Significant increase" is a more neutral and formal expression than "remarkable surge," which can be seen as overly dramatic for an academic analysis.
"over 100 MT" -> "in excess of 100 MT"
Explanation: "In excess of" is a more formal expression than "over," which is somewhat informal and less precise in this context.

These changes aim to refine the vocabulary and tone of the essay to better align with academic standards, enhancing precision, formality, and clarity.

Band điểm Task Achivement ước lượng: 7

Band Score: 7.0
Explanation: The essay provides a clear overview of the main trends in the graph. It accurately identifies the key features of the graph, including the significant decline in coal production, the dramatic surge in natural gas production, and the relatively stable production of petroleum. The essay also makes appropriate comparisons between the trends of the three fuels.
How to improve: The essay could be improved by providing more specific details about the trends, such as the rate of decline in coal production or the rate of increase in natural gas production. The essay could also be improved by providing more detailed comparisons between the trends of the three fuels. For example, the essay could state that natural gas production surpassed coal production in the early 1990s and that by 2000, natural gas production was more than double that of coal.

Band điểm Coherence & Cohesion ước lượng: 7

Band Score: 7.0
Explanation: The essay logically organizes information and ideas, demonstrating clear progression throughout the response. It effectively presents a central topic in each paragraph, with a clear introduction, body, and conclusion. The use of cohesive devices is appropriate, although there are instances of minor repetition and some areas where the cohesion could be improved. For example, the transition between the discussion of coal and natural gas could be smoother. Overall, the essay meets the criteria for Band 7, but there are areas that could be enhanced for a higher score.
How to improve: To elevate the score to Band 8 or 9, the writer should focus on refining the use of cohesive devices to ensure they enhance the flow of ideas without drawing attention to themselves. Additionally, improving the logical connections between paragraphs and ensuring that each paragraph transitions seamlessly into the next would strengthen the overall coherence. Finally, ensuring that paragraphing is not only appropriate but also strategically enhances the argument can further improve the essay’s structure.

Band điểm Lexical Resource ước lượng: 7

Band Score: 7.0
Explanation: The essay demonstrates a sufficient range of vocabulary that allows for flexibility and precision in conveying the main features of the graph. The use of terms such as "surged," "plummeting," and "dominant" indicates an awareness of less common lexical items. However, there are occasional inaccuracies in word choice and collocation, such as "the least produced fuel" which could be more clearly stated as "the fuel with the lowest production levels." Additionally, there are minor errors in capitalization, such as "coal" and "petroleum" not being consistently capitalized when referenced. Overall, the vocabulary is adequate for the task but lacks the sophistication and precision required for a higher band score.

How to improve: To enhance the lexical resource score, the writer could focus on expanding their vocabulary further by incorporating more sophisticated and varied expressions. Additionally, ensuring consistent capitalization and refining word choices to avoid inaccuracies will improve clarity. Practicing the use of collocations and idiomatic expressions can also contribute to a more natural and fluent use of language.

Band điểm Grammatical Range & Accuracy ước lượng: 7

Band Score: 7.0
Explanation: The essay demonstrates a variety of complex structures and produces frequent error-free sentences, indicating good control of grammar and punctuation. However, there are a few grammatical errors and instances of awkward phrasing, such as the inconsistent capitalization of "coal" and "petroleum" and minor punctuation issues. These errors do not significantly impede communication but prevent the essay from achieving a higher band score.
How to improve: To enhance the grammatical range and accuracy, the writer should focus on refining sentence structures and ensuring consistent capitalization. Additionally, proofreading for minor errors and practicing more complex sentence forms could help achieve a higher level of accuracy and flexibility in grammar usage.
