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 outlines the stages of ethanol is produced by passing different stages.

Overall, this process contain 7 major steps. plants and trees grow is the first step for production and small step of the process is adding of microbes.

To begin with first stage for production is, firstly, to grow the plants and trees energy is required which they get from sunlight and carbon dioxide. After growing harvesting is done by farmers. The harvested material undergoes pre-processing machines and breakdown the particles in small components. The pre-processed materials are converted into cellulose.

To continue with second stage of production is, the cellulose goes through a processing facility where it is converted into sugar molecules. After this, mircobes ferment the sugars to produce ethnol. The produced ethanol is used for transportation such as cars, trucks and planes. These vehicles releases carbon dioxide back into the atmosphere which restart the cycle.

AI examiner evaluation

Task Achievement / Task Response: Band 6.0

The student successfully covers all the main steps in the circular biofuel production process, from the growth of plants and trees using sunlight and carbon dioxide to pre-processing, cellulose conversion, processing into sugars, fermentation by microbes, and the final production and consumption of ethanol which releases carbon dioxide back into the atmosphere. An overview is attempted at the beginning by stating the process contains major steps, though the reporting could be slightly more polished. Key features such as the cyclical nature involving carbon dioxide emissions from transport are accurately reported, meeting the basic requirements of Task 1 effectively.

Coherence and Cohesion: Band 6.0

The response is arranged into four paragraphs, providing a coherent overall structure that follows the stages of the diagram sequentially. Cohesive devices are used to signal progression, such as 'To begin with', 'After growing', and 'To continue with second stage', though some transitional phrases feel slightly mechanical or awkward (e.g., 'To continue with second stage of production is'). Paragraphing is utilised adequately to separate the introduction, overview, and body details, and referencing is mostly clear throughout the text.

Lexical Resource: Band 6.0

The vocabulary used is adequate for the task, incorporating appropriate process-related terms such as 'harvesting', 'pre-processing', 'cellulose', 'processing facility', 'sugar molecules', and 'ferment'. However, there are notable word-choice and spelling errors, such as 'ethnol' instead of ethanol, 'mircobes' instead of microbes, and awkward phrasing like 'passing different stages'. Less common vocabulary is attempted with limited success and some inaccuracies, placing the response firmly in the band 6 category.

Grammatical Range and Accuracy: Band 5.0

The student attempts a mix of simple and complex sentence forms, but grammatical control is inconsistent. There are several structural errors and awkward formulations, such as 'The diagram outlines the stages of ethanol is produced by passing different stages' and 'To begin with first stage for production is, firstly, to grow...'. Punctuation is also erratic, including a stray floating letter 'n' on its own line. While communication is not severely impeded, the frequency of grammatical and mechanical errors prevents the score from reaching band 6.
