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.

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 are 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 product. You have identified the main features and provided a clear overview in the introduction. The progression is logical, following the diagram chronologically. To reach a higher band, ensure that you explicitly highlight the key comparisons or significant transformations, such as the transition from a solid state to a liquid pulp. While the description is accurate, adding a bit more detail regarding the chemical or mechanical nature of the steps (e.g., the specific role of the strainer) would further enhance the development of your ideas.

Coherence and Cohesion — Band 7.0

The response is well-organized with a clear logical flow. You have used appropriate cohesive devices such as 'To begin with', 'Following this', and 'The next step' to guide the reader through the process. Paragraphing is used effectively to separate the initial agricultural stages from the industrial processing stages. The progression of ideas is smooth, and referencing is clear throughout the text. To improve, you could vary your cohesive devices slightly more to avoid a somewhat mechanical feel, but the current structure is already very effective for a process description.

Lexical Resource — Band 6.5

You have used a sufficient range of vocabulary to describe the process, including terms like 'saplings', 'harvested', 'crushed', and 'amine oxide'. The language is generally precise and appropriate for an academic report. There are no significant spelling or word-choice errors. To achieve a higher score, try to incorporate more sophisticated collocations or less common technical terms related to manufacturing processes, such as 'raw material', 'chemical treatment', or 'synthetic fibres', which would demonstrate a more flexible and precise control of vocabulary.

Grammatical Range and Accuracy — Band 7.0

The response demonstrates a good control of grammatical structures. You have successfully used a mix of simple and complex sentences, such as 'The liquid is then filtered through a strainer which allows the fibres to get separated from the pulp.' The majority of your sentences are error-free, and the punctuation is accurate. There is a minor awkwardness in the phrase 'after which are they are harvested', which should be 'after which they are harvested'. Overall, your control of grammar is strong, and the occasional minor slip does not impede communication.
