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 diagram illustrates the process of manufacturing fabric from bamboo. Overall, the task involves several stages beginning with planting and harvesting of bamboo plants and ending with bamboo being transformed into fibres which are spun and weaved to make fabric. To begin with, bamboo saplings are planted in the soil in the spring season. A few months are required for the plants to develop into bamboo, after which they are harvested in the autumn season. Following this, the harvested bamboo is put through a cutter and is sliced into strips which are further crushed to result in a liquid pulp. The liquid is then filtered through a strainer which allows the fibres to get separated from the pulp. The next step involves softening the fibres that have been separated from the pulp. This is done by adding water mixed with amine oxide. The smoothened fibres are then spun to make yarn. The threads are then woven to make various kinds of fabrics like shirts, socks etc.

Task Achievement / Task Response — Band 6.5

The response effectively covers all stages of the bamboo manufacturing process, from planting to the final product. You have successfully identified the main features and provided a clear, logical summary. To reach a higher band, ensure you include a more distinct 'overview' paragraph that highlights the cyclical or transformative nature of the process, rather than just listing the steps. While you mention the stages well, the report could be improved by explicitly grouping the mechanical and chemical phases to provide a more analytical perspective on the process as a whole.

Coherence and Cohesion — Band 6.0

The response is logically organized, with a clear progression from the beginning to the end of the process. You use cohesive devices such as 'To begin with', 'Following this', and 'The next step' to guide the reader through the stages. However, the text is presented as a single block paragraph. For a process description, it is highly recommended to use at least two paragraphs—perhaps separating the initial harvesting/mechanical stages from the chemical/finishing stages—to improve the visual and structural flow of the report.

Lexical Resource — Band 6.5

You demonstrate a good range of vocabulary appropriate for a process description, such as 'saplings', 'harvested', 'crushed', and 'amine oxide'. The terminology is accurate and relevant to the diagram provided. To improve, try to incorporate more varied verbs and precise nouns to avoid repetition. For instance, instead of using 'make' twice in the final sentence, you could use 'manufacture' or 'produce'. The vocabulary is sufficient for the task and allows for clear communication of the technical steps involved.

Grammatical Range and Accuracy — Band 6.5

The grammar is generally accurate, and you use a mix of simple and complex sentence structures effectively. There are no major errors that impede communication. You handle the passive voice well, which is essential for describing processes (e.g., 'is sliced', 'is then filtered'). To aim for a higher band, try to incorporate a wider variety of complex structures, such as relative clauses or participle phrases, to increase the sophistication of your writing. For example, instead of 'The liquid is then filtered', you could write 'The resulting liquid is then filtered, a process which allows the fibres to be separated'.
