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 6.5)

The diagram illustrates how fabric is produced from bamboo that involves various distinct stages.

Overall, the process consists of nine steps, beginning with growing the bamboo and ending with the creation of clothing items such as t-shirts and socks. The bamboo undergoes several stages of physical and chemical processing before being spun and woven into fabric.

To start with, first stage is growing bamboo plants during the spring weather. Later, these plants are harvested in the autumn season, after which bamboos are stalked down into pieces using a saw. These strips, then subsequently crushed to produce liquid pulp. This pulp is then filtered as a result separating long fibres from liquid. Afterwards the fibres are softened using water and amine oxide, marking the transition from a raw plant material to a workable textile fibre.

Once softened, the fibres are spun into yarns, which is subsequently woven to fabrics. In the final stage, the fabric is used to produce various clothing items, such as t-shirts and socks, completing the transformation from plant to the finished product.

Task Achievement / Task Response: Band 6.5

The student successfully addresses all parts of the task by outlining the main features of the bamboo fabric manufacturing process. An appropriate overview is provided in the second paragraph, capturing the total number of steps and the overall transformation from raw plant material to finished garments. All nine steps are accurately reported and sequenced logically, following the visual data from planting and harvesting through to spinning, weaving, and final clothing production. Comparisons and transitions between physical and chemical processing are handled well. The response meets the criteria for Band 7, as all parts of the prompt are covered clearly with relevant details supported by the diagram.

Coherence and Cohesion: Band 6.5

The response demonstrates clear logical organisation and progression throughout. The writing is structured into appropriate paragraphs: an introduction, an overview, and body paragraphs detailing the sequential steps. Cohesive devices such as 'To start with', 'Later', 'after which', 'subsequently', and 'Once softened' are used effectively to guide the reader through the linear and branching stages of the process. Reference words like 'these plants' and 'this pulp' maintain clear continuity. While cohesion is generally well-managed, some transitions feel slightly mechanical, placing this response comfortably at a Band 7 level.

Lexical Resource: Band 6.5

The student uses a sufficient range of vocabulary appropriate for an academic process description, incorporating domain-specific terms such as 'liquid pulp', 'amine oxide', 'textile fibre', and 'woven'. Less common items and collocations are attempted with reasonable success, such as 'physical and chemical processing' and 'workable textile fibre'. However, there are minor lexical inaccuracies, such as 'bamboos are stalked down' (where 'stalked down' is unnatural and likely meant 'cut') and missing articles or prepositions like 'first stage is growing' and 'woven to fabrics'. Despite these slips, the vocabulary is adequate to convey the intended meaning clearly, aligning with Band 6.5 or 7.0; given the precision in technical terms, a Band 7 is justified.

Grammatical Range and Accuracy: Band 5.5

The student demonstrates a mix of simple and complex sentence structures, including relative clauses and participial phrases (e.g., 'marking the transition from a raw plant material to a workable textile fibre'). There are several grammatical errors and awkward phrasings present, such as 'fabric is produced from bamboo that involves' (agreement/modifier issue), 'first stage is growing' (missing article), 'These strips, then subsequently crushed' (missing auxiliary verb 'are'), and 'woven to fabrics' (incorrect preposition). Although these errors occur, they do not impede communication. The control over grammar is characteristic of a Band 6.
