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 pictorial diagram illustrates the process of manufacturing fabric products from bamboo. Overall, there are 9 steps in this procedure; the first is the cultivation of bamboo plants, and the final step is the production of bamboo fabric products.

The first 6 steps can be grouped as producing and processing bamboo to make fibres. It starts with planting bamboo plants in spring and later on harvesting them in the autumn season. After the harvesting is completed, the plants are split into small strips, which are then crushed into a liquid pulp. This pulp is passed through a filter that separates the long fibres from the liquid. Finally, these fibres are softened by adding water and amine oxide. The chemical treatment stage is crucial for transforming raw plant material into a pliable fibre.

In the remaining steps, the softened fibres are wrapped in a spinning motion to form a ball of yarn. Then this yarn is used to make fabric by a technique called weaving. Ultimately, the fabric that is made through this technique is used to make clothes such as socks and shirts in the final step.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The response effectively covers all stages of the bamboo manufacturing process. You have successfully identified the main features and provided a clear overview of the nine-step procedure. The division of the process into two logical phases—producing fibres and manufacturing products—is a strong analytical approach that helps the reader follow the sequence. All parts of the prompt are addressed, and the information is accurate based on the provided diagram. To reach a higher band, ensure that you explicitly highlight the most significant comparisons or trends, such as the transition from raw material to chemical processing, which you have done well here.

Coherence and Cohesion — Band 7.5

The response is logically organized with a clear progression from the introduction to the final product. Paragraphing is used effectively to separate the two main phases of production. Cohesive devices such as 'The first 6 steps', 'In the remaining steps', and 'Ultimately' are used appropriately to guide the reader through the process. The flow of information is smooth, and referencing is clear throughout the text. The structure is coherent, and the relationship between the steps is easy to follow, meeting the requirements for a high band score in this criterion.

Lexical Resource — Band 7.0

You have used a good range of vocabulary appropriate for a process description, such as 'cultivation', 'pliable', 'chemical treatment', and 'spinning motion'. The terminology is precise and relevant to the context of manufacturing. There are no significant errors in word choice or spelling. While the vocabulary is accurate and functional, incorporating a few more sophisticated collocations or less common lexical items related to industrial processes could elevate the response further. Overall, the range is sufficient and used with good control.

Grammatical Range and Accuracy — Band 7.5

The writing demonstrates a good command of grammatical structures. You have successfully used a mix of simple and complex sentences, such as 'This pulp is passed through a filter that separates the long fibres from the liquid.' Punctuation is accurate, and the sentence construction is generally error-free. The use of passive voice, which is essential for process descriptions, is handled correctly throughout. There are no major grammatical errors that impede communication, and the control over complex structures is consistent, which is characteristic of a high-level response.
