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 5.0)

The information I am getting from this diagram is how a biofuel called ethanol is produced. Here we are starting our production from planting and growing the trees after they are fulling grown the harvesting person will harvest the trees and take them to the pre processing place where they will pre process the trees using machines and get the cellulose which they will send to the processing places where they will the experiments with chemicals so that they can get the sugars in which later the microbes will add and the ethanol gas will produced and in further time if will give to the transport industries for cars, trucks, and even planes out of these all the carbon dioxide gas will produced and they will go to the cycle to the first step where the plants and trees are growing the energy in which sunlight and carbon dioxide were including.

Task Achievement / Task Response — Band 5.0

The response covers the main stages of the process, from planting to the final use of ethanol. However, the report lacks a clear overview or summary of the process as a whole, which is a requirement for Task 1. The description is overly narrative and informal, focusing on the 'person' harvesting rather than the objective process. While the main features are identified, the lack of a formal structure and the inclusion of unnecessary personal commentary ('The information I am getting from this diagram') prevents a higher score. To improve, focus on describing the technical stages objectively without referring to yourself or the diagram itself.

Coherence and Cohesion — Band 5.0

The response is written as a single, long paragraph, which makes it difficult to follow. There is a lack of logical paragraphing to separate the different stages of the process. Cohesive devices are either missing or used in a very repetitive and mechanical way, such as the constant use of 'and' to link clauses. There is no clear progression of ideas; the text reads more like a stream of consciousness than a structured report. To improve, use clear paragraphing to group stages (e.g., preparation, processing, and final output) and use a wider variety of linking words like 'subsequently', 'following this', and 'thereafter'.

Lexical Resource — Band 5.0

The vocabulary is quite limited and repetitive. Phrases like 'the harvesting person', 'the processing places', and 'the experiments' are imprecise and do not reflect the technical nature of the diagram. There is a reliance on basic, everyday language rather than academic terminology appropriate for a process description. For example, 'get the sugars' is too informal; 'extract the sugars' would be more accurate. The range of vocabulary is insufficient to convey the process with precision. To improve, focus on using specific technical verbs and nouns related to industrial processes, such as 'convert', 'fermentation', 'distillation', and 'raw materials'.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors that occasionally impede clarity. There are issues with verb tense consistency, such as 'ethanol gas will produced' (passive voice error) and 'if will give to' (incorrect pronoun and modal usage). Sentence structures are largely simple or poorly constructed compound sentences. There is a lack of complex sentence structures, and punctuation is almost entirely absent, which makes the text difficult to read. To improve, focus on mastering the passive voice, which is essential for describing processes, and ensure that subjects and verbs agree correctly throughout your sentences.
