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 cultivation of the plant to the production of finished clothing.

Overall, the process consists of nine main stages, beginning with the planting of bamboo in spring and ending with the production of garments. The bamboo is progressively transformed from solid plant material into fibres, which are the spun into yarn and woven into fabric.

Initially, bamboo plants are grown in spring and harvested in autumn when they are ready. The harvested bamboo is then cut into thin strips. These strips are subsequently crushed to produce a liquid pulp. The pulp undergoes a filtering process, during which the long fibres are separated from the remaining liquid.

In the next stage, the extracted fibres are softened by adding water and amine oxide. Once they have been sufficiently softened, they are spun to produce yarn. The yarn is then woven together to form bamboo fabric. Finally, this fabric is used to manufacture various clothing items, such as T-shirts and socks.

Thus, the production involves a series of mechanical and chemical processes that gradually convert harvested bamboo into usable textile material and, ultimately, finished garments

Task Achievement / Task Response — Band 7.5

The student has successfully addressed all parts of the task by providing a clear and comprehensive overview of the bamboo fabric manufacturing process. The response accurately outlines all nine stages shown in the diagram, beginning with planting in spring and culminating in the production of finished garments such as T-shirts and socks. Key features, such as the transition from solid plant material to liquid pulp and subsequent spinning and weaving phases, are reported logically and concisely. There are no notable omissions or misinterpretations of the visual data. The overview effectively captures the essence of the process without introducing extraneous or irrelevant information. The response fully satisfies the requirements of this criterion.

Coherence and Cohesion — Band 8.0

The response demonstrates a clear and logical organisation from beginning to end. Information is presented in a well-sequenced manner that mirrors the chronological steps of the diagram. The student makes effective use of cohesive devices to guide the reader smoothly through the process, such as 'Initially', 'subsequently', 'In the next stage', 'Once', and 'Finally'. Paragraphing is handled appropriately, dividing the introduction, overview, and specific process stages into distinct, readable blocks. Referencing throughout the text is clear, ensuring that pronouns and transitional phrases link ideas seamlessly without mechanical repetition or awkwardness.

Lexical Resource — Band 7.0

The student uses a sufficient and appropriate range of vocabulary relevant to an academic process description, such as 'cultivation', 'progressively', 'extracted fibres', and 'textile material'. Less common lexical items are employed with reasonable precision, including 'amine oxide', 'liquid pulp', and 'garments'. There is only one minor typographical slip in the second paragraph ('which are the spun into yarn', where 'the' should likely be 'then'), but this does not impede comprehension in any way. Word choice and collocations are natural and well-suited to the formal, objective tone required for Academic Task 1.

Grammatical Range and Accuracy — Band 7.5

The response exhibits a wide variety of sentence structures, successfully combining simple, compound, and complex forms. Grammatical control is strong throughout, with the vast majority of sentences being completely error-free. The passive voice is used appropriately and accurately to describe industrial and chemical processes (e.g., 'bamboo plants are grown', 'The harvested bamboo is then cut', 'the extracted fibres are softened'). Punctuation is accurate, and verb tenses are handled consistently and correctly in the present simple tense, which is standard for describing processes. The minor typo mentioned under lexical resource does not detract significantly from an otherwise excellent grammatical performance.
