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 successfully covers all stages of the bamboo manufacturing process, from planting to the final production of fabric. The overview is clear and effectively summarizes the transformation from raw material to finished product. The main features are highlighted logically, and the progression of the process is easy to follow. However, to reach a higher band, the response could benefit from more explicit comparisons or a more sophisticated synthesis of the stages, rather than simply listing them sequentially. The inclusion of specific examples like 'shirts, socks' is good, but ensuring the technical terminology is precise throughout would further enhance the clarity of the report.

Coherence and Cohesion — Band 7.0

The response is logically organized, with a clear introduction, an overview, and body paragraphs that follow the chronological order of the process. Cohesive devices such as 'To begin with', 'Following this', and 'The next step' are used effectively to guide the reader through the stages. Paragraphing is appropriate, separating the initial growth phase from the industrial processing phase. The flow of information is smooth, and referencing is clear throughout. To improve, the writer could experiment with a wider variety of cohesive links to avoid a slightly mechanical feel in the transition between sentences.

Lexical Resource — Band 6.0

The vocabulary is adequate for the task, with accurate use of process-related terms such as 'saplings', 'harvested', 'filtered', and 'woven'. The range is sufficient to describe the steps clearly. However, the lexical range is somewhat limited; using more precise academic vocabulary would elevate the response. For instance, instead of 'put through a cutter', terms like 'mechanically processed' or 'shredded' would be more appropriate. There are no significant spelling errors, and the word choice is generally precise enough to convey the intended meaning without ambiguity.

Grammatical Range and Accuracy — Band 6.5

The response demonstrates a good control of grammar, with a mix of simple and complex sentence structures. Most sentences are error-free, and the use of passive voice—which is essential for process descriptions—is handled well (e.g., 'bamboo saplings are planted', 'liquid is then filtered'). Punctuation is generally accurate. While the grammatical range is functional, the writer could incorporate more varied complex structures, such as relative clauses or participle phrases, to demonstrate greater flexibility. Overall, the grammar is reliable and does not impede communication.
