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 7.5)

The diagram illustrates the process of manufacturing fabric from bamboo, from the initial planting of bamboo plants to the production of finished clothing.

Overall, the process consists of nine main stages. The first six stages involve growing and processing bamboo to produce soft fibres, while the final three stages transform these fibres into yarn, fabric and eventually clothing.

Initially, bamboo plants are grown in spring and harvested in autumn. The harvested bamboo is then cut into small strips, which are subsequently crushed to produce a liquid pulp. Next, this pulp is filtered to separate the long fibres from the liquid. The extracted fibres are then softened by adding water and amine oxide.

In the next stage, the softened fibres are spun to produce yarn. The yarn is then woven to create fabric. Finally, this fabric is used to manufacture finished products, such as T-shirts and socks. Thus, the process moves from the cultivation of bamboo through several mechanical and chemical stages before the final textile products are produced.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The student successfully covers all parts of the task by clearly outlining the entire nine-step process of manufacturing fabric from bamboo. An effective overview is provided in the second paragraph, which captures the main divisions of the process: growing and processing into soft fibres, followed by transformation into yarn, fabric, and clothing. The progression of the stages is accurately reported, including details such as the cutting, crushing, filtering, and softening phases, and concludes appropriately with the final textile products like T-shirts and socks. All key information from the visual data is accurately represented without any significant omissions or misinterpretations.

Coherence and Cohesion — Band 7.5

The response is logically sequenced and easy to follow. Ideas flow smoothly from one stage of the manufacturing process to the next. Paragraphing is used appropriately and effectively, with a clear introduction, an overview paragraph, a body paragraph detailing the initial and intermediate steps, and a final paragraph covering the concluding stages. Cohesive devices such as 'Initially', 'The harvested bamboo is then', 'subsequently', 'Next', 'In the next stage', and 'Finally' are managed well to guide the reader through the sequence without mechanical repetition.

Lexical Resource — Band 7.0

The student demonstrates a sufficient and appropriate range of vocabulary for this task type. Appropriate process-related vocabulary is used accurately throughout, such as 'manufacturing', 'cultivation', 'liquid pulp', 'extract', 'softened fibres', 'spun', and 'woven'. Less common vocabulary items are integrated with good awareness of style and collocation, such as 'initial planting', 'subsequently crushed', and 'mechanical and chemical stages'. Word choices are precise, and there are no noticeable spelling or word-choice errors that impede communication.

Grammatical Range and Accuracy — Band 7.5

The writing exhibits a good variety of complex sentence structures, such as participial phrases ('from the initial planting...') and relative clauses, alongside accurate simple structures. The majority of sentences are error-free, and grammatical control is strong throughout. Passive voice constructions, which are essential for describing a manufacturing process, are handled correctly (e.g., 'bamboo plants are grown', 'is then cut', 'are then softened'). Punctuation is accurate, and minor slips are virtually absent.
