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 process of manufacturing fabric from bamboo. At a glance, it is observed that it is a lengthy process.

Overall, it is a lengthy process consisting of several stages, beginning with the planting of bamboo in spring and ending with the production of fabric. The process involves harvesting, cutting, crushing, filtering and treating the bamboo fibres before they are spin into yarn and woven into fabric.

The process starts with bamboo being planted in the spring season. It is then allowed to grow until autumn, when it is harvested. After harvesting, the bamboo is cut into small strips. These strips are subsequently crushed to produce a liquid pulp.

In the next stage, the liquid pulp is filtered in order to separate the long fibres from the liquid. The extracted fibres are then treated with amine oxide and water, which makes them softer and suitable for further processing. After this, the softened fibres are spun into yarn. Finally, the yarn is woven to produce the finished fabric.

AI examiner evaluation

Task Achievement / Task Response — Band 7.0

The response effectively covers all stages of the bamboo manufacturing process, from planting to the final fabric production. You have successfully identified the main features and provided a clear, logical summary. The overview is concise and accurately reflects the nature of the process. To reach a higher band, ensure that you explicitly mention the key inputs or environmental conditions if they are highlighted in the diagram, such as the specific chemicals or the duration of growth. Overall, the information is well-selected and the response is fully developed, meeting the requirements of the task.

Coherence and Cohesion — Band 7.5

The response is logically organized, with a clear progression from the initial planting stage to the final weaving process. Paragraphing is used effectively to separate the introduction and overview from the detailed process steps. You have used cohesive devices such as 'In the next stage', 'After this', and 'Finally' to guide the reader through the sequence. The flow of information is smooth and easy to follow. The use of referencing is accurate, and the structure of the essay is coherent throughout.

Lexical Resource — Band 6.5

You have used a sufficient range of vocabulary to describe the process accurately, such as 'harvesting', 'crushing', 'filtered', and 'woven'. The terminology is appropriate for a technical process description. While the vocabulary is functional and precise, incorporating a few more sophisticated collocations or synonyms for 'lengthy process' or 'liquid pulp' would enhance the lexical variety. There are no significant errors in word choice or spelling, and the language used is natural and fits the context of an academic report.

Grammatical Range and Accuracy — Band 7.0

The response demonstrates a good command of grammatical structures. You have successfully used passive voice constructions, which are essential for describing processes (e.g., 'bamboo is cut', 'pulp is filtered', 'fibres are treated'). There is a mix of simple and complex sentence structures, and the majority of sentences are error-free. One minor error was noted: 'before they are spin into yarn' should be 'before they are spun into yarn'. Aside from this, the control of grammar and punctuation is strong and does not impede communication.
