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 process diagram illustrates the stages involved in manufacturing process of fabric from bamboo plants.

Overall, it follows a sequence of nine stages. It starts with planting bamboo plants and ends with producing shirts and socks. It undergoes a number of processes, namely planting, harvesting, cutting, crushing, filtering, softening, spinning and weaving.

The process initiates with planting bamboo plants in the spring season. When autumn season arrives, the fully-grown bamboo plants are harvested by farmers. Later, bamboo sticks go through sharp-edged circular machine that cuts it into strips and separates the sticks and flower part.

Then, crushed strips produce liquid pulp which is filtered through a funnel in order to separate long fibres from the liquid solution. To soften the long fibre strips, water and amine oxide is added. After the fibres are softened, they are spinned into round yarn balls. Finally, the yarn is weaved into different patterns to make fabric pieces such as shirts and and socks.

AI examiner evaluation

Task Achievement / Task Response: Band 7.0

The response successfully addresses all parts of the task by providing a clear overview of the nine-stage process of manufacturing bamboo fabric, from planting to finished clothing items such as shirts and socks. The main features are appropriately selected and reported, and the progression of the steps is clearly traced from the top row down to the bottom row. The response shows a clear overview as requested by the task rubrics, noting the starting and ending points. To reach a higher level, the response could integrate more detailed comparisons or deeper elaboration on specific mechanical or chemical transformations occurring across the intermediate stages, such as the exact function of the amine oxide.

Coherence and Cohesion: Band 7.0

The text demonstrates a clear logical organisation and progression throughout the nine distinct steps of the diagram. The writer makes effective use of sequential cohesive devices such as "Overall", "It starts with", "The process initiates with", "Later", "Then", and "Finally" to guide the reader smoothly through the manufacturing stages. Paragraphing is used appropriately to separate the introduction, the overview, and the sequential body details. Referencing is generally clear, though minor improvements in linking the transition between sentences could make the cohesion even more fluid, avoiding a slightly mechanical feel in places.

Lexical Resource: Band 6.5

The response employs an adequate and largely accurate range of vocabulary suited to a process diagram, using terms such as "manufacturing", "harvested", "crushed strips", "liquid pulp", "filtered", and "spun yarn". There are some successful attempts to use less common lexical items related to the diagram, like "amine oxide" and "long fibres". However, there are minor lexical inaccuracies and word-form errors, such as "spinned" (should be spun) and "weaved" (should be woven), as well as a minor repetition of "bamboo plants". These occasional slips show solid control while keeping the communication clear and natural.

Grammatical Range and Accuracy: Band 6.5

The writing demonstrates a functional mix of simple and complex sentence structures, including subordinate clauses and temporal markers like "When autumn season arrives". The verb tenses are consistently and correctly maintained in the present simple passive to describe the manufacturing process. There are some minor grammatical errors and awkward phrasing, such as "manufacturing process of fabric" missing an article, and a minor typo with a repeated conjunction ("shirts and and socks"). However, these errors are relatively infrequent, do not impede communication, and the punctuation remains generally sound throughout.
