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 8.5)

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

Overall, there are nine main stages in the process, beginning with the planting of bamboo in spring and ending with the manufacture of fabric products such as clothes. The process involves both mechanical procedures, such as cutting, crushing, spinning and weaving, and chemical treatment, particularly when the fibres are softened.

Initially, bamboo plants are grown in spring and are harvested in autumn once they have matured. The harvested bamboo is then cut into thin strips, which are subsequently crushed to produce a liquid pulp. In the next stage, this pulp is passed through a filter, which separates the long fibres from the liquid.

Following filtration, the fibres are softened by adding water and amine oxide. Once they have become sufficiently soft, they are spun into yarn. This yarn is then woven to create bamboo fabric. Finally, the resulting material can be used to manufacture finished textile products, as illustrated by a T-shirt and a pair of socks.

In terms of the overall sequence, the first two stages are seasonal agricultural activities, whereas the remaining seven stages constitute the industrial processing of bamboo into usable fabric. Thus, the raw plant undergoes a series of physical and chemical transformations before becoming a finished textile product.

Task Achievement / Task Response — Band 8.0

The response is excellent. You have clearly identified all stages of the bamboo manufacturing process, from cultivation to the final product. The overview is well-crafted, effectively highlighting the distinction between the agricultural and industrial phases. You have successfully selected the main features and provided a logical summary without unnecessary detail. The comparison between mechanical and chemical processes adds depth to the report, demonstrating a high level of task fulfillment. All parts of the prompt are addressed comprehensively, and the information is presented in a clear, professional manner that is highly appropriate for an Academic Task 1 response.

Coherence and Cohesion — Band 8.5

The response is logically organized with a clear progression from the beginning to the end of the process. Paragraphing is used effectively to separate the introduction, the detailed process description, and the concluding summary. Cohesive devices such as 'Initially', 'In the next stage', 'Following filtration', and 'Thus' are used naturally and accurately to guide the reader through the sequence. The referencing is precise, and the flow of information is smooth throughout the text, making it very easy to follow the manufacturing stages.

Lexical Resource — Band 8.0

You demonstrate a wide and precise range of vocabulary suitable for describing a technical process. Terms such as 'cultivation', 'matured', 'subsequently', 'filtration', and 'transformations' are used accurately and in the correct context. The language is sophisticated and natural, showing a strong command of collocations. There are no errors in word choice, and the vocabulary is varied enough to avoid repetition, which contributes to the professional tone of the report.

Grammatical Range and Accuracy — Band 8.5

The writing displays a high level of grammatical control. You have used a variety of complex sentence structures, including passive voice constructions ('are grown', 'are harvested', 'is passed', 'are softened'), which are essential for describing processes. Punctuation is accurate, and there are no noticeable grammatical errors. The majority of your sentences are error-free, and the control over tense and aspect is consistent throughout the description. The structure is both flexible and accurate.
