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 manufacturing of a fabric from bamboo.

Overall, the process begins with the sowing of bamboo plants and ends with the production of dresses for daily use.

In the initial stage, farmers sow the bamboo plants in the season of spring and wait for the autumn season. In the autumn season, farmers harvest the trees through manual labor. Next, they are transferred to a cutting machine, which cuts them into strips.

In the subsequent stage, strips of bamboo are crushed so that the liquid pulp can be extracted from them. Then, the pulp is passed through a filter to separate the long fibers from liquid pulp. In addition, long fibers are softened by mixing water and amine oxide in them.

At the final stage, soft fibers are spun to make yarn. Yarn is then transferred into fabric by the process of weaving. Finally, the useful products such as shirts, socks, and other items are made.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

The response successfully covers all stages of the bamboo manufacturing process, from the initial sowing to the final product. You have identified the main features and presented them in a logical sequence. However, to reach a higher band, the response would benefit from a more analytical approach. For instance, rather than just listing the steps, you could highlight the transformation of the raw material into a chemical-based pulp, which is a key technical aspect of the diagram. The overview is clear, but could be slightly more detailed regarding the nature of the process (e.g., mentioning that it involves both mechanical and chemical stages). Overall, the task is addressed well.

Coherence and Cohesion — Band 7.0

The response is logically organized, with clear paragraphing that follows the chronological stages of the process. You use a variety of cohesive devices such as 'In the initial stage', 'Next', 'In the subsequent stage', and 'At the final stage' to guide the reader through the text. The progression of ideas is smooth and easy to follow. To improve further, ensure that the transition between sentences is not overly mechanical; varying the structure of your linking phrases would make the flow feel more natural and sophisticated.

Lexical Resource — Band 6.5

You have used a sufficient range of vocabulary to describe the process, including terms like 'manual labor', 'liquid pulp', 'amine oxide', and 'weaving'. The word choice is generally accurate and appropriate for a technical description. There are no significant spelling errors. To achieve a higher band, try to incorporate more precise collocations or less common technical vocabulary related to manufacturing processes, such as 'extraction', 'chemical treatment', or 'spinning process', to demonstrate a more flexible and sophisticated command of the language.

Grammatical Range and Accuracy — Band 7.0

The response demonstrates a good control of grammar with a mix of simple and complex sentence structures. Most sentences are error-free, and the punctuation is used correctly. For example, the use of passive voice in 'strips of bamboo are crushed' and 'pulp is passed through a filter' is appropriate for a process description. There are no major grammatical errors that impede communication. To improve, you could experiment with more complex sentence structures, such as using participle clauses (e.g., 'Having been crushed, the bamboo strips are then filtered...') to increase the variety and sophistication of your writing.
