IELTS Writing Task 1 question

The diagram below shows how fabric is manufactured from bamboo.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

Student answer (Band 6.0)

The diagram illustrates the stages involved in manufacturing fabric from bamboo.

Overall, the process begins with the harvesting of bamboo plants and involves several mechanical and chemical stages before the material is transformed into ready-made garments.

First, bamboo plants are harvested in autumn and cut into strips using a sharp blade. The strips are then crushed to produce liquid pulp, which is subsequently filtered to separate the long fibres from the liquid. Next, the fibres are soaked in a mixture of water and amine oxide in order to soften them.

Once softened, the fibres are spun to produce yarn. This yarn is then converted into sheets, which are subsequently woven. Finally, the woven material is transformed into ready-made clothes, completing the process.

AI examiner evaluation

Task Achievement / Task Response — Band 5.5

The response covers all key stages of the manufacturing process from planting bamboo to producing finished garments. The overview effectively summarises the main steps and the transformation involved. However, a significant constraint affects this criterion: the length requirement of at least 150 words is not met, as the student's text contains only 122 words. Consequently, the development is slightly curtailed, pulling the score down to a 5.5 in accordance with the task achievement descriptors for under-length responses.

Coherence and Cohesion — Band 6.5

The text displays a clear logical organisation and progression throughout. The writer successfully structures the process into distinct paragraphs covering the beginning, middle, and final stages. Cohesive devices such as 'First', 'The strips are then', 'subsequently', and 'Once softened' are used appropriately and naturally to guide the reader through the sequence. Paragraphing is handled well, ensuring that the flow of information mirrors the linear progression of the diagram. Referencing is also clear and precise.

Lexical Resource — Band 6.0

The vocabulary used is adequate and relevant for describing a manufacturing process, featuring appropriate terms such as 'harvested', 'crushed', 'filtered', 'softened', and 'woven'. The student attempts some less common and topic-specific vocabulary items like 'amine oxide', 'liquid pulp', and 'ready-made garments' with good control. Word choice and collocations are generally natural, and there are no notable spelling or lexical errors that impede communication. A slightly wider variety of synonyms for sequence transitions would elevate the score further.

Grammatical Range and Accuracy — Band 6.5

The response demonstrates a good control of grammatical structures, successfully combining simple and complex sentences. Examples include passive constructions ('bamboo plants are harvested', 'are soaked in a mixture') which are highly appropriate for process descriptions, as well as participial phrases ('Once softened, the fibres are spun'). Punctuation is accurate, and the majority of sentences are grammatically sound and error-free. The structural range is sufficient to meet the requirements of a band 7.
