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 flow chart illustrates the step-by-step process of producing fabric from bamboo, starting with cultivation and ending with finished clothing items.

Overall, the process comprises nine distinct stages, categorized into three main phases: agricultural cultivation, chemical processing into raw fiber, and mechanical textile manufacturing.

The initial phase begins in the spring with the planting of bamboo crops. By autumn, the mature bamboo is harvested and subsequently cut into strips using a circular saw. These strips are then crushed to create a liquid pulp mixture.

In the mid-processing phase, the mixture undergoes filtration using a funnel to separate the long bamboo fibers from the excess liquid. Following separation, these extracted fibers are treated with a mixture of water and amine oxide, which serves to soften them into a workable material.

In the final phase, the softened fibers are spun into yarn. This yarn is then woven to produce textile fabric sheets, which are ultimately used to manufacture finished clothing products such as t-shirts and socks.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The response effectively covers all stages of the bamboo manufacturing process, from cultivation to the final product. You have successfully identified the main features and grouped them into logical phases, which provides a clear overview of the process. The summary is accurate and follows the sequence of the diagram well. To reach a higher band, you could incorporate more specific comparisons or highlight the transformation of the material more explicitly, such as noting the transition from a solid state to a liquid pulp and back to a solid fiber. Overall, the response is well-structured and addresses the prompt comprehensively.

Coherence and Cohesion — Band 7.5

The response is logically organized, with a clear introduction, a well-defined overview, and distinct paragraphs for each phase of the process. The use of cohesive devices such as 'The initial phase', 'In the mid-processing phase', and 'In the final phase' creates a smooth flow of information. The progression from one step to the next is easy to follow, and the paragraphing is used appropriately to separate the different stages of production. The text is coherent throughout, and the referencing is clear, making the information easy to digest.

Lexical Resource — Band 7.0

You have used a good range of vocabulary appropriate for a process description, such as 'cultivation', 'subsequently', 'extracted', and 'workable material'. The terminology is precise and fits the context of the diagram well. There are no significant errors in word choice or collocation. To move toward a higher band, you could integrate slightly more sophisticated or technical vocabulary related to industrial manufacturing, such as 'chemical synthesis' or 'textile fabrication', to demonstrate a wider and more flexible range of lexical items.

Grammatical Range and Accuracy — Band 7.5

The response demonstrates a good command of complex sentence structures, such as the use of participial phrases ('starting with cultivation', 'following separation') and relative clauses. The grammar is highly accurate, with no noticeable errors in tense or syntax. The majority of sentences are error-free, and the punctuation is used correctly to support the clarity of the text. The variety of structures used is sufficient to convey the process clearly and professionally, meeting the requirements for a high band score.
