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 depicts the process of manufacturing fabric from bamboo.

Overall, there are nine sequential steps involved in the process, starting with planting bamboo and ending with fabric production. It is not particularly labour-intensive, requiring minimal manual intervention and some basic technical equipment.

In the initial stages, bamboo plants are sown in spring and then harvested in autumn once they have matured. After harvesting, the stalks are mechanically cut into strips, which are subsequently crushed to form a liquid pulp, marking the end of the preparatory phase.

In the next sequence, the liquid pulp is filtered to separate the long fibres from the rest of the material. These extracted fibres are then softened using water and amine oxide, a chemical agent. Once softened, the material is spun into yarn, after which it is woven to produce fabric. Finally, the fabric is turned into garments, such as socks and T-shirts, completing the production cycle.

Task Achievement / Task Response — Band 7.5

The response successfully covers all the main stages of the bamboo fabric manufacturing process, from the initial planting of bamboo to the final production of garments. The overview effectively summarises the entire linear process by noting the total number of steps and the nature of the operations involved. Key features are clearly highlighted, such as sowing in spring, harvesting in autumn, mechanical cutting, crushing into liquid pulp, filtering long fibres, softening with chemical agents, spinning into yarn, and weaving. Comparisons or sequential links are appropriately established, such as marking the end of the preparatory phase and completing the production cycle. The information is accurately reported directly from the visual prompt without any significant omissions or misinterpretations.

Coherence and Cohesion — Band 7.5

The text is well-structured and demonstrates a clear logical progression from start to finish. The introduction succinctly outlines the scope of the diagram, while the second paragraph provides a sound overarching summary. Subsequent paragraphs are organised chronologically to reflect the manufacturing stages. Cohesive devices are used naturally and effectively to guide the reader through the sequence, utilising time markers and transitional phrases such as 'In the initial stages', 'After harvesting', 'subsequently', 'In the next sequence', and 'Finally'. Paragraphing is handled logically, separating the introduction, overview, preparation phase, and final manufacturing steps clearly and appropriately.

Lexical Resource — Band 6.5

The student employs a sufficient and flexible range of vocabulary appropriate for an academic task describing a manufacturing process. Less common and precise items related to the diagram are used effectively, including 'sequential', 'intervention', 'preparatory phase', 'amine oxide', and 'production cycle'. Word choices are generally accurate and appropriate for the context of a process diagram. While there are no major lexical errors, the vocabulary remains slightly standard in a few areas, demonstrating good control without reaching the pinnacle of rare and highly sophisticated idioms or collocations, which comfortably places it in the Band 7 range.

Grammatical Range and Accuracy — Band 7.5

The response demonstrates a strong command of grammatical structures, successfully blending simple and complex sentences. The writer makes effective use of participial phrases and subordinate clauses, such as 'starting with planting bamboo and ending with fabric production' and 'once they have matured'. The majority of sentences are entirely error-free, and control over tense and punctuation is robust throughout. Minor slips or awkwardness are absent, and complex structures are handled with good accuracy, allowing the communication to flow smoothly. The grammar fully supports the clear presentation of the sequential information.
