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 pictorial illustrate the production of biofuel called ethonol in the environment.
Overall, It has 8 step to produce ethanol,starting with the plants and ending with the usage of ethanol in various type of vehicle.It is a circular process because carbon dioxide release from vehicle gose into air again. Furthermore, it is consumed by plants and trees.
Initially, plants and trees absrob the energy from sunlight and carbon dioxide.After that, fully grown plants are harvested and they are caried out by a truck.hereafter, the plants put into the machine for pre-processing and cellulose is produced. in the next stage, this cellulose

Task Achievement / Task Response — Band 4.0
The response fails to meet the minimum word count requirement of 150 words, as it is significantly under-length at 101 words. Consequently, the description of the process is incomplete, stopping abruptly after the cellulose production stage. While the introduction and overview attempt to identify the main features, the failure to complete the description means the task is only partially addressed. To improve, you must ensure you describe all stages of the process shown in the diagram and provide a more comprehensive summary of the key features to meet the length requirement.
Coherence and Cohesion — Band 5.0
The response shows some attempt at logical organization, using an introduction and an overview paragraph. However, the abrupt ending prevents a coherent flow of information. Cohesive devices are used, such as 'Initially' and 'After that', but the overall structure is severely compromised by the incomplete nature of the text. Paragraphing is attempted, but the final paragraph is cut off mid-sentence, which disrupts the progression of the report. To improve, focus on completing the full sequence of the process and ensuring that each stage is linked clearly to the next.
Lexical Resource — Band 5.0
The vocabulary is generally adequate for the task, with terms like 'biofuel', 'cellulose', and 'pre-processing' used correctly. However, there are several spelling errors, such as 'pictorial' (instead of 'diagram'), 'ethonol' (ethanol), 'absrob' (absorb), and 'caried' (carried). These errors are noticeable and detract from the quality of the writing. To reach a higher band, you should focus on accurate spelling and attempt to use a wider range of vocabulary to describe the mechanical and biological stages of the process more precisely.
Grammatical Range and Accuracy — Band 5.0
The response contains a mix of simple and some complex sentence structures, but there are frequent grammatical errors. Examples include 'The pictorial illustrate' (subject-verb agreement), 'It has 8 step' (pluralization), and 'carbon dioxide release from vehicle gose' (tense and spelling). Punctuation is also inconsistent, with missing spaces after periods. While the meaning is generally clear, these persistent errors in basic grammar and mechanics limit the score. Focusing on subject-verb agreement and consistent tense usage will help improve your accuracy.
