IELTS Writing Task 1 question

 

The diagram below shows how a biofuel called ethanol is produced.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Student answer (Band 6.0)

The diagram illustrates the process of producing of ethanol biofuel.

It is clear that ethanol biofuel process consist of eight stages , beginning with plats and grow and ending with the production of ethanol .this process is a cycling process because the carbon dioxide include starting and outcome.

At the first stage , The plants and trees grown by an energy from sunlight and carbon dioxide then labours harvested the trees and transported by a tractor . Next pre processing machine processed those trees and plants as a cellulose . the celluloses are also processed in a lab with some cemichels after this processed it made as sugars then the last stages its a microbes added and the final outcome Ethanol.

After producing ethanol it use as fuel for running some engine of cars, lorries ,airplane . when the car,lorrie,airplane run by use the biofuel ethanol it create carbon dioxide as a outcome . the carbon dioxide mix with the air and then again the trees and plant as their energy source from nature , completing the cycle .

AI examiner evaluation

Task Achievement / Task Response — Band 6.0

You have successfully identified the main stages of the ethanol production process and noted the cyclical nature of the carbon dioxide. However, the response lacks a clear overview of the process as a whole. While you mention the stages, the description is somewhat fragmented, and the connection between the chemical processing and the final output could be more clearly articulated. To improve, ensure you provide a concise summary of the overall process in the introduction and group the stages more logically to highlight the transformation from raw material to fuel.

Coherence and Cohesion — Band 6.0

The response is organised into paragraphs, which helps the reader follow the progression of the cycle. However, the use of cohesive devices is somewhat mechanical and occasionally inaccurate, such as the phrase 'after this processed it made as sugars'. The referencing is sometimes unclear, making it difficult to track the flow of the process. To reach a higher band, focus on using a wider variety of linking words and ensure that each sentence flows naturally into the next, rather than relying on simple transitions like 'Next' or 'At the first stage'.

Lexical Resource — Band 6.0

Your vocabulary is generally adequate for the task, but there are several spelling errors (e.g., 'plats', 'cemichels') and word choice issues (e.g., 'labours harvested' instead of 'labourers harvest'). The range of vocabulary is limited, and you rely on basic terms to describe technical processes. To improve, try to incorporate more precise terminology related to industrial processes, such as 'fermentation', 'conversion', or 'by-product', and pay closer attention to spelling and word forms to ensure your writing appears more professional.

Grammatical Range and Accuracy — Band 5.5

There are frequent grammatical errors throughout the text, including issues with subject-verb agreement ('ethanol biofuel process consist'), article usage ('the last stages its a microbes'), and sentence structure. While the meaning is generally clear, these errors are persistent and distract the reader. You rely mostly on simple sentence structures; to improve, you should practice using more complex sentences with accurate subordination and relative clauses. Additionally, proofreading for basic errors like missing plurals or incorrect verb tenses will significantly improve the accuracy of your writing.
