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 5.5)

The diagram outlines the stages which involoves in production of a biofuel called ethanol. The first step is sowing the crop then provide it favourable conditions through which it take energy such as sunlight and cardon dioxide. After the first stage the process steadily continue and plants and trees grow and then it's turn of harvesting process. When the harvesting is successfuly completed the pre-processing begins which resulted in production of cellulose which then used to do processing in labortary. The labortary processing produced sugars which don't have microbes in it, so now the necessity is addition of microbes through which Ethanol is produced. Now Ethanol is made and ready to use to fulfil our biofuel demand. It can be used in many vehicles such as cars, trucks and aeroplanes. They all produce carbon dioxied which then used to give energy to plants and the process continoue in the cycle.

AI examiner evaluation

Task Achievement / Task Response — Band 5.5

The response covers the main stages of the ethanol production process, from crop growth to final usage. However, the description is somewhat simplistic and lacks a clear overview or summary of the key features as required by Task 1. The explanation of the cycle is a bit repetitive, and some technical details (such as the specific conversion of cellulose to sugar) are described in a very basic manner. To improve, you should aim to group the information more logically and provide a clearer summary of the overall process in the introduction or conclusion.

Coherence and Cohesion — Band 5.5

The response is organized chronologically, which helps the reader follow the process. However, the paragraphing is non-existent, as the entire response is written as a single block of text. Cohesive devices are used, such as 'The first step', 'After the first stage', and 'Now', but they are somewhat mechanical and repetitive. The flow between sentences is generally logical, but the lack of paragraph breaks makes the text feel dense and less professional. Using clear paragraphing to separate the stages of the process would significantly improve the structure.

Lexical Resource — Band 5.5

The vocabulary is adequate for the task but lacks the precision and variety expected at higher bands. There are several spelling errors, such as 'involoves', 'labortary', and 'carbon dioxied'. Additionally, some word choices are slightly unnatural, such as 'it's turn of harvesting process' and 'the necessity is addition of microbes'. To achieve a higher score, you should focus on using more precise technical terminology related to industrial processes and ensure accurate spelling of key terms.

Grammatical Range and Accuracy — Band 5.0

The response contains a mix of simple and complex sentence structures, but there are frequent grammatical errors that occasionally impede the flow. Examples include 'stages which involoves in production', 'through which it take energy', and 'the process steadily continue'. Subject-verb agreement and tense consistency are inconsistent throughout the text. While the meaning is generally clear, the frequency of these errors prevents the writing from reaching a higher band. Focusing on proofreading for basic subject-verb agreement and verb tense consistency would be very beneficial.
