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 method used to produce fabric from bamboo.

Overall, the linear process consists of 9 main stages. The production commences with planting bamboo plants at specific times of the year and concludes with fabric being used to produce a range of clothing.

At the initial stage, planting of bamboo plants take place in spring season. After that the planted bamboos are harvested in autumn. In the subsequent stage, the harvested bamboo is cut and transformed into strips. Afterwards, liquid pulp is extracted by crushing the strips. The liquid pulp undergoes filtration where long fibers are separated from the liquid.

Following filtration, water and amine oxide are added in order to make the fibers soft. Once this stage is completed, the fiber undergoes spinning to build yarn. In the penultimate stage, the yarn is woven to transform into fabric. Finally, a variety of clothing products are produced from the fabric.

AI examiner evaluation

Task Achievement / Task Response — Band 7.0

The response successfully identifies the main features of the bamboo manufacturing process. You have clearly outlined the nine stages from planting to the final product. The overview is concise and provides a good summary of the linear nature of the process. However, to reach a higher band, you could improve by making more explicit comparisons or highlighting the transformation of the raw material more dynamically. For instance, noting the shift from a natural state to a chemical-treated state would add depth. Overall, you have addressed all parts of the task effectively and provided a clear, logical summary of the provided diagram.

Coherence and Cohesion — Band 7.0

The response is logically organized, with a clear progression from the initial planting stage to the final clothing production. You have used a range of cohesive devices such as 'After that', 'In the subsequent stage', 'Afterwards', and 'Following filtration' to guide the reader through the process. The paragraphing is appropriate, separating the introduction/overview from the detailed process description. The flow is smooth and easy to follow, and the use of referencing is generally clear. There is no evidence of mechanical or repetitive usage, which demonstrates a good level of control over the structure of the report.

Lexical Resource — Band 7.0

You have used a sufficient range of vocabulary to describe the process accurately, including terms like 'extracted', 'filtration', 'penultimate', and 'transformed'. The language is precise enough to convey the technical nature of the diagram. While the vocabulary is functional and appropriate for the task, it lacks the 'less common' or more sophisticated lexical items that would push the score into the 8.0 range. There are no significant errors in word choice or collocation, and the vocabulary used is consistently natural and fits the context of a process description well.

Grammatical Range and Accuracy — Band 7.0

The response demonstrates a good control of grammar. You have used a mix of simple and complex sentence structures, such as 'Once this stage is completed, the fiber undergoes spinning to build yarn.' There are a few minor errors, such as 'planting of bamboo plants take place' (should be 'takes place') and 'in spring season' (should be 'in the spring season'). However, these errors are infrequent and do not impede communication. The majority of your sentences are error-free, and your control over punctuation and tense consistency is generally strong throughout the report.
