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 6.5)

The flow diagram illustrates the sequential manufacturing process of producing clothing fabric from bamboo plants. The production is a process consisting of nine steps, beginning with the agricultural cultivation of the raw material in specific seasons and culminating in the creation of finished textile products. The process combines both mechanical actions and chemical treatments to transform the raw plant into usable cloth.In the initial stage, bamboo is planted during the spring. After a period of growth, the mature stalks are harvested in the autumn. Following the harvest, the bamboo stalks are cut into thin strips. These strips are then mechanically crushed to break down the structure and form a liquid pulp. Following this, the softened fibers are spun into tightly wound balls of yarn. In the penultimate step, this yarn is woven together to create a cohesive sheet of fabric. Finally, the woven fabric is tailored into commercial clothing items, such as t-shirts and socks.

AI examiner evaluation

Task Achievement / Task Response: Band 6.0

The student provides a clear overview and successfully summarises the main stages of the manufacturing process from bamboo to fabric and clothing. The response covers the entire sequence from planting and harvesting to crushing, filtering, spinning, weaving, and final clothing production. However, the student misses a couple of intermediary steps shown in the diagram, specifically step 5 (filtering to separate long fibres from liquid) and step 6 (softening fibres with water and amine oxide), jumping directly from crushing to spinning. Despite this omission, the key features and overall progression are adequately reported and supported by the visual data.

Coherence and Cohesion: Band 6.5

The response is logically organized with a clear overall progression that mirrors the stages in the diagram. Cohesive devices are used effectively to guide the reader through the sequence, such as 'In the initial stage', 'After a period of growth', 'Following this', and 'Finally'. Paragraphing is handled appropriately, with an introductory overview followed by a body paragraph detailing the sequential steps. Referencing is generally clear and appropriate, though the transition between sentences could be slightly more refined to achieve a higher band descriptor.

Lexical Resource: Band 6.0

The vocabulary used is generally adequate and appropriate for an Academic Task 1 response, featuring topic-specific terms such as 'cultivation', 'mature stalks', 'mechanically crushed', 'liquid pulp', and 'penultimate step'. There are attempts to use less common vocabulary, and word choices are mostly accurate. However, the range is somewhat limited, and minor inaccuracies or unnatural collocations occasionally appear, which prevents the response from reaching a higher band score.

Grammatical Range and Accuracy: Band 6.5

The student demonstrates a good mix of simple and complex sentence structures, incorporating participial phrases and subordinate clauses effectively (e.g., 'The production is a process consisting of nine steps, beginning with...'). Grammar and punctuation are generally well controlled. While there are a few minor slips or repetitive structures, the majority of sentences are error-free, and grammatical errors do not impede communication at any point.
