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 7.0)

The diagram illustrates the process of manufacturing fabric from bamboo from the initial planting of bamboo plants to the production of finished bamboo products.

Overall, there are nine stages that begins with growing and harvesting bamboo and ends with weaving the processed fibres into fabric. The manufacturing stages involve cutting and crushing the bamboo, separating and softening its fibres, and finally turning them into yarn.

First, bamboo plants are grown in spring and harvested in autumn when they are ready. The harvested bamboo is then cut into thin strips using a machine. These strips are subsequently crushed to produce a liquid pulp. Next, the pulp is filtered so that the long fibres are separated from the liquid.

In the following stage, the fibres are softened by adding water and amine oxide. Once they have been softened, they are spun into yarn. The yarn is then woven to produce bamboo fabric. Finally, this fabric is used to make various finished products, such as clothing and socks.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The student covers all parts of the prompt well, accurately summarising the main features of the bamboo fabric manufacturing process. The response successfully highlights the transition from raw agricultural material through chemical processing into spun yarn, woven fabric, and final products like clothing and socks. The overview provided in the second paragraph effectively outlines the principal stages of the nine-step process. All essential data points from the diagram are reported in a logical sequence without any significant omissions or misinterpretations. Ideas are well-developed and grounded directly in the visual source material, demonstrating a clear understanding of the task requirements and meeting the criteria for a high band.

Coherence and Cohesion — Band 7.5

The response is logically organized with a clear progression from the introduction through the manufacturing stages to the final products. Paragraphing is used appropriately to separate the introduction, overview, and specific procedural steps. Cohesive devices such as 'First', 'Subsequently', 'Next', and 'In the following stage' are employed effectively to guide the reader through the linear and branching flow of the diagram. Referencing is clear throughout, and the overarching structure of the text ensures that information flows smoothly without any noticeable disruptions or mechanical sounding transitions.

Lexical Resource — Band 6.5

The student demonstrates a sufficient and appropriate range of vocabulary relevant to a process diagram, using terms such as 'manufacturing', 'processed fibres', 'liquid pulp', and 'amine oxide' correctly. Less common lexical items are attempted with good awareness of collocation and style, as seen in phrases like 'initial planting', 'readily harvested', and 'finished products'. Word choice is generally precise, and spelling is accurate throughout. While the vocabulary is not exceptionally sophisticated or rare enough to merit a top-tier band 9, it is flexible and fully adequate for handling the task with clarity and precision.

Grammatical Range and Accuracy — Band 7.0

A good variety of complex and simple sentence structures is used throughout the response. The student successfully employs passive voice structures typical of process descriptions, such as 'bamboo plants are grown', 'is cut into thin strips', and 'are softened by adding water'. The majority of sentences are error-free, and punctuation is handled well. There are occasional minor awkwardnesses, such as the subject-verb agreement slip in 'there are nine stages that begins' (should be 'begin'), but these are isolated slips that do not impede communication. Overall control of grammar is solid.
