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 by which etganol is produced from the plants and how it is subsequently used as a biofuel.

Overall the production of ethanol is a cyclical process consisting of several stages,beginning with the growth and harvesting of plant and ending with the use of ethanol as a fuel.according to the diagram importantly, the carbon dioxide released when ethanol is burned and absorbed by growing plants and making the process as continious cycle.

initially plant and tree grow using by sunlight and observing carbon dioxide from the atmosphere.once they are fully grow they are harvested and sent for pre-processing.During this stage the plant material is preparted and converted to cellulose. then start processing to produce sugar.

Next, new microbes added to sugar which cause them to ferment and produce into ethanol fuel. and this ethanol used as a fuel for various transport such as car, truck and aeroplane

finally, the transport produce carbondioxide and it is absorbed by by plants during growth and it is recycle backrd to the beginning of the process to continue ethanol production.

AI examiner evaluation

Task Achievement / Task Response: Band 7.0

The response successfully covers all parts of the task by outlining the main stages of how ethanol is produced and highlighting the circular nature of the process, including the release and reabsorption of carbon dioxide. The overview is clearly stated at the beginning, noting that the production is a cyclical process. Key features such as harvesting, pre-processing into cellulose, processing into sugars, fermentation via microbes, and final consumption by transport vehicles are all reported correctly based on the visual data. The response meets the requirements of a Band 7 because it presents a clear overall picture and addresses all parts of the prompt, though the extension of ideas could be slightly more polished to reach the higher bands.

Coherence and Cohesion: Band 6.5

The text demonstrates a coherent overall arrangement with a logical progression from the initial growth of plants to the final recycling of carbon dioxide. Paragraphing is used to separate different stages of the process, which helps readability. Cohesive devices such as 'initially', 'next', and 'finally' are employed to guide the reader through the sequence of events. However, cohesion sometimes feels slightly mechanical, and referencing between sentences could be smoother to achieve a higher band. For instance, transitional phrases are basic and would benefit from greater variety and flexibility.

Lexical Resource: Band 5.5

The student uses an adequate range of vocabulary for the task, successfully attempting less common terms such as 'cyclical process', 'ferment', and 'absorption' (though spelling errors affect some of these). There are noticeable lexical errors, such as the misspelling 'etganol', 'continious' instead of continuous, and 'preparted'. Word choice is sometimes imprecise, such as 'new microbes added to sugar which cause them to ferment and produce into ethanol fuel'. These errors place the response firmly in the middle band, as the vocabulary is minimally adequate for communication but contains frequent spelling and word-form inaccuracies.

Grammatical Range and Accuracy: Band 5.0

The response contains a mix of simple and complex sentence forms, but control over grammar and punctuation is inconsistent. There are frequent errors in articles ('the plants', 'using by sunlight'), verb forms ('once they are fully grow', 'this ethanol used as'), prepositions ('absorbed by by plants'), and punctuation, including missing capital letters at the beginning of sentences. These errors reflect a limited control over complex structures and place the grammar at a lower band level. While communication is not entirely obscured, the density of grammatical errors noticeably impedes the fluency of the reading experience.
