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 5.5)

The diagram illustrates the manufacturing process of fabric from bamboo.

Overall, there are nine different stages, starting by planting bamboo plants and ending with final stage of wearing cloths.

The process begins with planting bamboo plants during the Spring. When bamboo plants reach their maturity, they are harvested manually during the Autumn. Later, a machine cuts the bamboo plants into strips, which are crushed to make liquid pulp. Then, crushed strips go through a filter so that long fibers can be separated from the liquid.

In the next step, the long fibres need to be softened. Water and amine oxide are used for that. Subsequently, the soften fibres are turned into yarn by spinning. The yarn is then woven into fabric. In the final stage, the fabric is used to make various items of clothing.

Task Achievement / Task Response — Band 5.0

The response covers all stages of the manufacturing process, from harvesting to the final product. However, the response is under the 150-word minimum length requirement, which negatively impacts the score. While the main features are identified, the description lacks the depth and detail required to fully develop the response. For instance, the transition between the chemical processing and the final weaving could be expanded with more descriptive language regarding the transformation of the material. To improve, ensure you meet the word count by providing more detailed descriptions of the processes shown in the diagram, such as elaborating on the specific chemical or mechanical changes at each stage.

Coherence and Cohesion — Band 5.5

The response is logically organized, following the chronological order of the manufacturing process. The use of cohesive devices such as 'The process begins with', 'Later', 'Then', and 'In the next step' helps guide the reader through the stages. However, the paragraphing is limited; the response would benefit from a clearer separation between the initial harvesting stages and the subsequent chemical/manufacturing stages. While the progression is clear, the overall structure is somewhat mechanical, and the limited length prevents the use of more sophisticated linking phrases that would elevate the flow of the text.

Lexical Resource — Band 5.5

The vocabulary used is adequate for the task, with terms like 'maturity', 'harvested', 'crushed', and 'amine oxide' being used correctly. However, the range is somewhat limited and repetitive. There is a reliance on simple verbs and basic sentence structures. To reach a higher band, you should aim to incorporate more precise technical vocabulary related to industrial processes, such as 'extraction', 'conversion', or 'synthetic', and avoid repeating words like 'plants' or 'fibres' too frequently. The current range is sufficient for the task but lacks the flexibility and precision required for higher scores.

Grammatical Range and Accuracy — Band 5.5

The response demonstrates a mix of simple and complex sentence structures. Most sentences are grammatically accurate, and errors are rare and do not impede communication. For example, 'When bamboo plants reach their maturity, they are harvested manually' is a well-constructed complex sentence. However, the range of structures is limited; the response relies heavily on simple declarative sentences. To improve, try to incorporate a wider variety of complex grammatical structures, such as passive voice constructions (which are particularly useful for process descriptions) and relative clauses, to demonstrate greater control over sentence variety.
