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 6.5)

The illustration demonstrates the manufacturing process of fabric using bamboo.

Overall, the bamboo fabric runs through nine steps to get ready. The procedure involves using fully grown bamboo plants, processing harvested parts of a plant and ending up fabricating clothes and socks.

The bamboo plants are fully grown during the spring season. As fall season appears, these plants get harvested by a worker in order to cut them into strips by a cutter during the third step. These strips get crushed in order to make liquid pulp. During the fifth step, a filter is used to drain water from the pulp and separates long fibres from liquid.

In the sixth step, these fibers undergo a softening process where water and amine oxide will be added to the fibres to make them soft. Next this mixture needs to get spin to make yarn followed by winding together to make fabric. Finally, the fabric reaches consumers in the form of clothes.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

The response successfully covers all stages of the bamboo manufacturing process, from the initial growth phase to the final product. You have identified the main features and provided a clear, logical summary of the nine steps. However, the response could be improved by providing a more analytical overview. Instead of simply stating there are nine steps, you could highlight the transformation from raw organic material to a chemical-based synthetic fibre. While all parts of the task are addressed, the description of the chemical process (step 6) is slightly simplified, and more precise terminology regarding the industrial nature of the process would elevate the response.

Coherence and Cohesion — Band 7.0

The response is logically organized, following the chronological order of the diagram. You use transition words such as 'As', 'During', 'In the sixth step', and 'Finally' to guide the reader through the process. Paragraphing is used effectively to separate the introduction/overview from the detailed steps. However, some cohesive devices feel slightly mechanical, and the connection between sentences could be smoother. For instance, the transition between the harvesting and the crushing stage could be more fluid. Overall, the progression of ideas is clear and easy to follow throughout the text.

Lexical Resource — Band 6.0

You demonstrate an adequate range of vocabulary for the task, using terms like 'manufacturing process', 'harvested', 'liquid pulp', and 'softening process'. There are some minor inaccuracies in word choice, such as 'runs through nine steps to get ready' and 'get spin', which should be 'be spun'. While you successfully describe the technical stages, the vocabulary is somewhat basic. To reach a higher band, try to incorporate more precise technical collocations related to manufacturing, such as 'raw material', 'chemical treatment', or 'industrial production'. The current vocabulary is sufficient to convey the meaning clearly but lacks sophistication.

Grammatical Range and Accuracy — Band 6.0

The response contains a mix of simple and complex sentence structures. You demonstrate control over basic grammar, but there are several recurring errors. For example, 'these plants get harvested' is slightly informal; 'are harvested' would be more appropriate for an academic report. There are also errors in verb forms, such as 'needs to get spin' instead of 'needs to be spun'. Additionally, some articles are missing or misused, such as 'by a worker' (which is fine) but 'by a cutter' (which sounds like a person rather than a machine). While these errors do not impede communication, they limit the score.
