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 flowchart illustrates the sequential multi-stage process of manufacturing commercial textile fabric from raw bamboo plants.

Overall, the production line comprises nine distinct stages, which can be broadly categorized into initial agricultural cultivation, chemical processing, and final textile manufacturing. The entire cycle spans from seasonal outdoor planting to the creation of finished consumer clothing items.

In the opening stages, bamboo is planted during the spring and harvested later in the autumn. The harvested stalks are then mechanically cut into thin strips before being crushed to produce a liquid pulp. This pulpy mixture is subsequently passed through a specialized funnel filter to separate the long, usable fibers from the remaining liquid.

The isolated fibers are then softened using a processed combination of water and amine oxide chemical solution. Following this softening phase, these refined fibers are spun tightly to form durable yarn, which is then woven into structured sheets of fabric. In the final stage, this raw fabric is manufactured into commercial clothing items, such as t-shirts and socks.

Task Achievement / Task Response — Band 7.5

The response effectively summarizes the process of manufacturing fabric from bamboo. You have clearly identified the main stages, from cultivation to the final product, and provided a logical overview. The inclusion of specific details, such as the mechanical cutting and the chemical softening process, demonstrates a strong grasp of the information provided in the diagram. The response is well-structured and covers all key features of the process without unnecessary detail, meeting the requirements for a high band score.

Coherence and Cohesion — Band 7.5

The essay is logically organized, with a clear progression from the initial agricultural phase to the final manufacturing stage. Paragraphing is used effectively to separate the overview from the detailed process description. Cohesive devices such as 'subsequently', 'following this', and 'in the final stage' are used naturally to guide the reader through the sequence of events. The flow of information is smooth, and the relationship between the different stages of the process is clearly articulated.

Lexical Resource — Band 7.5

You have used a range of precise vocabulary appropriate for a process description, such as 'sequential', 'cultivation', 'specialized', and 'durable'. The terminology is accurate and contributes to a professional tone. There are no significant errors in word choice or collocation, and the vocabulary is sufficiently varied to describe the technical aspects of the bamboo manufacturing process effectively.

Grammatical Range and Accuracy — Band 8.0

The writing exhibits a high level of grammatical control. You have successfully employed a mix of simple and complex sentence structures, such as the use of participial phrases ('Following this softening phase...') and relative clauses. The punctuation is accurate, and there are no noticeable grammatical errors. The majority of sentences are error-free, demonstrating a strong command of English syntax and morphology.
