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 illustrate the process of how a biofuel called ethanol is produced.

Overall, its cleared that process have 9 total steps. Starting from the Plant and tree grow through Energy from the sunlight plus carbon dioxide to finish with producing a carbon dioxide.

In the beginning, individual harvest the trees and convert into the minor pieces through pre -proecessing phase . After that, its completed the step of transformation into cellulosebform . From Cellulose its transmuted into sugar by processing with the lab equipements. Before its modify into Ethanol . Microbes added into sugar and modify it into Ethanol.

Ethanol is made at this step. From now onward, Ethanol is provding carbion dioxide to cars,and for trucks as well as also give carbon dioxide to airoplanes. The carbon dioxide again eveporate and provide energy to plant for growth. These steps will process again to produce the biofuel called ethanol.

Task Achievement / Task Response — Band 6.0

The response covers the main stages of the ethanol production process, from plant growth to the final use in vehicles. However, the description of the process is somewhat superficial and contains inaccuracies, such as stating that the process produces carbon dioxide as a final product rather than ethanol. While the main features are identified, the explanation of the cycle is slightly confused, particularly regarding the role of carbon dioxide. To improve, ensure that the technical steps are described with greater precision and that the relationship between the stages is clearly articulated to reflect the diagram accurately.

Coherence and Cohesion — Band 6.0

The essay is organised into paragraphs, which helps the reader follow the sequence of events. However, the use of cohesive devices is often mechanical or inaccurate, such as 'From now onward' and 'After that, its completed'. The referencing is sometimes unclear, for example, the use of 'its' to refer to the process or the stage. While there is a logical progression from the start to the end of the cycle, the flow between sentences is occasionally disjointed, which hinders the overall coherence of the report.

Lexical Resource — Band 5.5

The vocabulary is generally limited and repetitive. There are several instances of word-choice errors and non-standard collocations, such as 'minor pieces' instead of 'small pieces' or 'cellulosebform'. The term 'transmuted' is used incorrectly in this context. While the student attempts to use process-related vocabulary like 'harvest', 'convert', and 'microbes', the lack of precision and frequent spelling errors (e.g., 'proecessing', 'equipements', 'eveporate') limit the score. A wider range of precise, topic-specific vocabulary is needed to convey the information more effectively.

Grammatical Range and Accuracy — Band 5.5

The response relies on a mix of simple and some attempted complex structures, but there are frequent grammatical errors throughout. Common issues include subject-verb agreement ('process have', 'individual harvest'), incorrect verb forms ('its cleared', 'its completed'), and missing articles. Punctuation is also inconsistent, with irregular spacing around commas and periods. While the meaning is generally understandable, the high frequency of errors in basic sentence construction prevents the response from reaching a higher band. Focusing on subject-verb agreement and consistent verb tense usage would significantly improve the accuracy.
