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 producing bamboo fabric, beginning with the cultivation of bamboo and ending with the manufacture of clothing.

Overall, the process consists of nine main stages, starting with the planting and harvesting of bamboo and finishing with the weaving of yarn into fabric. Broadly, the process involves growing the bamboo, extracting and treating its fibres, and finally converting these fibres into textile material.

Initially, bamboo is planted in spring and harvested in autumn. The harvested plants are then cut into strips, which are subsequently crushed to produce pulp. This pulp is passed through a filter in order to separate the long fibres from the liquid. Once the fibres have been extracted, they are softened by adding water and amine oxide, making them suitable for further processing.

In the final stages, the softened fibres are spun to produce yarn. The yarn is then woven to create bamboo fabric, which is ultimately used to manufacture clothing items such as shirts and socks. Thus, through a series of mechanical and chemical processes, bamboo is transformed from a natural plant into finished textile products.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The response successfully covers all parts of the task by providing a clear and comprehensive summary of the bamboo fabric manufacturing process. In the introduction, the candidate outlines the overall scope of the diagram, moving from cultivation to clothing production. The overview effectively captures the main stages, noting that the process involves growing, treating fibres, and converting them into textiles. Key steps such as harvesting in autumn, crushing to produce pulp, filtering long fibres, and spinning yarn are reported accurately and logically. The information is well selected, and appropriate comparisons or sequential links are made throughout the text, fully satisfying the requirements for Task Achievement at a high level.

Coherence and Cohesion — Band 7.5

The text is logically organised with a clear progression from the beginning to the end of the manufacturing process. The response begins with a general introduction and an overview paragraph, followed by detailed body paragraphs that trace the sequential steps. Cohesive devices are used naturally and effectively, such as 'beginning with', 'subsequently', 'Once', and 'In the final stages'. Paragraphing is managed appropriately, separating the introductory and overview elements from the detailed sequential stages, ensuring the reader can follow the complex linear process with ease and without any confusion regarding referencing or cohesion.

Lexical Resource — Band 7.5

The candidate demonstrates a wide and appropriate vocabulary suited to a process diagram. Terms related to manufacturing and processing such as 'cultivation', 'subsequently', 'extracted', 'softened', and 'amine oxide' are deployed with precision. Less common lexical items are used naturally to describe technical steps, for instance, 'crushed to produce pulp' and 'woven to create bamboo fabric'. Word choice and collocations are generally accurate throughout the response, with only rare, minor slips, reflecting a flexible and sophisticated control of vocabulary that fully supports the clarity of the report.

Grammatical Range and Accuracy — Band 7.5

A wide variety of complex grammatical structures is employed accurately throughout the response. The candidate successfully integrates participial phrases and subordinate clauses, as seen in structures like 'beginning with the cultivation of bamboo' and 'Once the fibres have been extracted, they are softened by adding water'. The majority of sentences are error-free, and control over tense, voice, and punctuation is strong. Passive voice structures, which are essential for describing processes, are handled with excellent precision across the entire text, demonstrating a high degree of grammatical command and flexibility.
